The Existence of God

Other essays.

The existence and attributes of God are evident from the creation itself, even though sinful human beings suppress and distort their natural knowledge of God.

The existence of God is foundational to the study of theology. The Bible does not seek to prove God’s existence, but rather takes it for granted. Scripture expresses a strong doctrine of natural revelation: the existence and attributes of God are evident from the creation itself, even though sinful human beings suppress and distort their natural knowledge of God. The dominant question in the Old and New Testaments is not whether God is, but rather who God is. Philosophers both Christian and non-Christian have offered a wide range of arguments for God’s existence, and the discipline of natural theology (what can be known or proven about God from nature alone) is flourishing today. Some philosophers, however, have proposed that belief in God is rationally justified even without theistic arguments or evidences. Meanwhile, professing atheists have offered arguments against God’s existence; the most popular is the argument from evil, which contends that the existence and extent of evil in the world gives us good reason not to believe in God. In response, Christian thinkers have developed various theodicies, which seek to explain why God is morally justified in permitting the evils we observe.

If theology is the study of God and his works, then the existence of God is as foundational to theology as the existence of rocks is to geology. Two basic questions have been raised regarding belief in God’s existence: (1) Is it true ? (2) Is it rationally justified (and if so, on what grounds)? The second is distinct from the first because a belief can be true without being rationally justified (e.g., someone might irrationally believe that he’ll die on a Thursday, a belief that turns out by chance to be true). Philosophers have grappled with both questions for millennia. In this essay, we will consider what the Bible says in answer to these questions, before sampling the answers of some influential Christian thinkers.

Scripture and the Existence of God

The Bible opens not with a proof of God’s existence, but with a pronouncement of God’s works: “In the beginning God created the heavens and the earth.” This foundational assertion of Scripture assumes that the reader not only knows already that God exists, but also has a basic grasp of who this God is. Throughout the Old Testament, belief in a creator God is treated as normal and natural for all human beings, even though the pagan nations have fallen into confusions about the true identity of this God. Psalm 19 vividly expresses a doctrine of natural revelation: the entire created universe ‘declares’ and ‘proclaims’ the glorious works of God. Proverbs tells us that “the fear of the Lord” is the starting point for knowledge and wisdom (Prov. 1:7; 9:10; cf. Psa. 111:10). Denying God’s existence is therefore intellectually and morally perverse (Psa. 14:1; 53:1). Indeed, the dominant concern throughout the Old Testament is not whether God is, but who God is. Is Yahweh the one true God or not (Deut. 4:35; 1Kgs. 18:21, 37, 39; Jer. 10:10)? The worldview that provides the foil for Hebrew monotheism is pagan polytheism rather than secular atheism.

This stance on the existence of God continues into the New Testament, which builds on the foundation of the uncompromising monotheism of the Old. In his epistle to the Romans, the apostle Paul insists that God’s “eternal power and divine nature” are clearly perceived from the created order itself. Objectively speaking, there can be no rational basis for doubt about the existence of a transcendent personal creator, and thus there can be no excuse for unbelief (Rom. 1:20). Endued with a natural knowledge of our creator we owe God our honor and thanks, and our failure to do so serves as the primary basis for the manifestation of God’s wrath and judgment. The apostle’s robust doctrine of natural revelation has raised the question of whether anyone can truly be an atheist. The answer will depend, first, on how “atheist” is defined, and second, on what precisely Paul means when he speaks of people “knowing” God. If the idea is that all men retain some genuine knowledge of God, despite their sinful suppression of natural revelation, it’s hard to maintain that anyone could completely lack any cognitive awareness of God’s existence. But if “atheist” is defined as someone who denies the existence of God or professes not to believe in God, Romans 1 not only allows for the existence of atheists – it effectively predicts it. Atheism might then be understood as a form of culpable self-deception.

Paul’s convictions about natural revelation are put to work in his preaching to Gentile audiences in Lystra and Athens (Acts 14:15–17; 17:22–31). Paul assumes not only that his hearers know certain things about God from the created order but also that they have sinfully suppressed and distorted these revealed truths, turning instead to idolatrous worship of the creation (cf. Rom. 1:22–25). Even so, his appeals to general revelation are never offered in isolation from special revelation: the Old Testament Scriptures, the person of Jesus Christ, and the testimony of Christ’s apostles.

Elsewhere in the New Testament, the question of the existence of God is almost never explicitly raised, but rather serves as a foundational presupposition, an unquestionable background assumption. One exception would be the writer to the Hebrews, who remarks that “whoever would draw near to God must believe that he exists and that he rewards those who seek him” (11:6). In general, the New Testament is concerned less with philosophical questions about the existence of God than with practical questions about how sinners can have a saving relationship with the God whose existence is obvious. As in the Old Testament, the pressing question is never whether God is, but who God is. Is Jesus Christ the revelation of God in human flesh or not? That’s the crux of the issue.

Arguments for the Existence of God

Consider again the two questions mentioned at the outset. (1) Is belief in God true ? (2) Is it rationally justified ? One appealing way to answer both questions affirmatively is to offer a theistic argument that seeks to infer God’s existence from other things we know, observe, or take for granted. A cogent theistic argument, one assumes, would not only demonstrate the truth of God’s existence but also provide rational justification for believing it. There is a vast literature on theistic arguments, so only a sampling of highlights can be given here.

The first generation of Christian apologists felt little need to argue for God’s existence for the same reason one finds no such arguments in the New Testament: the main challenges to Christian theism came not from atheism, but from non-Christian theism (Judaism) and pagan polytheism. Not until the medieval period do we find formal arguments for the existence of God offered, and even then the arguments do not function primarily as refutations of atheism but as philosophical meditations on the nature of God and the relationship between faith and reason.

One of the most famous and controversial is the ontological argument of St. Anselm (1033–1109) according to which God’s existence can be deduced merely from the definition of God, such that atheism leads inevitably to self-contradiction. One distinctive of the argument is that it relies on pure reason alone with no dependence on empirical premises. Various versions of the ontological argument have been developed and defended, and opinion is sharply divided even among Christian philosophers over whether there are, or even could be, any sound versions.

Cosmological arguments seek to demonstrate that that the existence of the universe, or some phenomenon within the universe, demands a causal explanation originating in a necessary first cause beyond the universe. St. Thomas Aquinas (1225–1274) famously offered “Five Ways” of demonstrating God’s existence, each of which can be understood as kind of cosmological argument. For example, one of the Five Ways argues that any motion (change) has to be explained by some mover (cause).  If that mover itself exhibits motion, there must be a prior mover to explain it, and because there cannot be an infinite regress of moved movers, there must be an original unmoved mover : an eternal, immutable, and self-existent first cause. Other notable defenders of cosmological arguments include G. W. Leibniz (1646–1716) and Samuel Clarke (1675–1729), and more recently Richard Swinburne and William Lane Craig.

Teleological arguments , which along with cosmological arguments can be traced back to the ancient Greeks, contend that God is the best explanation for apparent design or order in the universe. Simply put, design requires a designer, and thus the appearance of design in the natural world is evidence of a supernatural designer. William Paley (1743–1805) is best known for his argument from analogy which compares functional arrangements in natural organisms to those in human artifacts such as pocket watches. While design arguments suffered a setback with the rise of the Darwinian theory of evolution, which purports to explain the apparent design of organisms in terms of undirected adaptive processes, the so-called Intelligent Design Movement has reinvigorated teleological arguments with insights from contemporary cosmology and molecular biology while exposing serious shortcomings in naturalistic Darwinian explanations.

In the twentieth century, the moral argument gained considerable popularity, not least due to its deployment by C. S. Lewis (1898–1963) in his bestseller Mere Christianity . The argument typically aims to show that only a theistic worldview can account for objective moral laws and values. As with the other theistic arguments there are many different versions of the moral argument, trading on various aspects of our moral intuitions and assumptions. Since such arguments are typically premised on moral realism —the view that there are objective moral truths that cannot be reduced to mere human preferences or conventions—extra work is often required to defend such arguments in a culture where moral sensibilities have been eroded by subjectivism, relativism, and nihilism.

Cornelius Van Til (1895–1987) gained some notoriety for his forceful criticisms of the “traditional method” of Christian apologetics which capitulated to “autonomous human reason.” Van Til held that any respectable theistic argument ought to disclose the undeniability of the triune God revealed in Scripture, not merely a First Cause or Intelligent Designer. He therefore advocated an alternative approach, centered on a transcendental argument for the existence of God, whereby the Christian seeks to show that human reason, far from being autonomous and self-sufficient, presupposes the God of Christianity, the “All-Conditioner” who created, sustains, and directs all things according to the counsel of his will. As Van Til put it, we should argue “from the impossibility of the contrary”: if we deny the God of the Bible, we jettison the very grounds for assuming that our minds have the capacity for rational thought and for reliable knowledge of the world.

Since the renaissance of Christian philosophy in the second half of the twentieth century, there has been renewed interest and enthusiasm for the project of developing and defending theistic arguments. New and improved versions of the classical arguments have been offered, while developments in contemporary analytic philosophy have opened up new avenues for natural theology. In his 1986 lecture, “Two Dozen (or so) Theistic Arguments,” Alvin Plantinga sketched out an entire A to Z of arguments for God, most of which had never been previously explored. Plantinga’s suggestions have since been expanded into a book-length treatment by other philosophers. The discipline of Christian natural theology is thriving as never before.

Basic Belief in the Existence of God

Still, are any of these arguments actually needed? Does confidence about God’s existence have to be funded by philosophical proofs? Since the Enlightenment, it has often been held that belief in God is rationally justified only if it can be supported by philosophical proofs or scientific evidences. While Romans 1:18–21 has sometimes been taken as a mandate for theistic arguments, Paul’s language in that passage suggests that our knowledge of God from natural revelation is far more immediate, intuitive, and universally accessible.

In the opening chapters of his Institutes of the Christian Religion , John Calvin (1509–1564) considers what can be known of God apart from special revelation and asserts that a natural knowledge has been universally implanted in mankind by the Creator: “There is within the human mind, and indeed by natural instinct, an awareness of divinity” ( Institutes , I.3.1). Calvin speaks of a sensus divinitatis , “a sense of deity,” possessed by every single person in virtue of being created in God’s image. This internal awareness of the Creator “can never be effaced,” even though sinful men “struggle furiously” to escape it. Our implanted natural knowledge of God can be likened in some respects to our natural knowledge of the moral law through the God-given faculty of conscience (Rom. 2:14-15). We know instinctively that it’s wrong to lie and steal; no philosophical argument is needed to prove such things. Similarly, we know instinctively that there is a God who made us and to whom we owe honor and thanks.

In the 1980s, a number of Protestant philosophers led by Alvin Plantinga, Nicholas Wolterstorff, and William Alston developed a sophisticated defense of Calvin’s notion of the sensus divinitatis . Dubbed the “Reformed epistemologists,” they argued that theistic beliefs can be (and normally should be) properly basic : rationally justified even without empirical evidences or philosophical proofs. On this view, believing that God exists is comparable to believing that the world of our experience really exists; it’s entirely rational, even if we can’t philosophically demonstrate it. Indeed, it would be quite dysfunctional to believe otherwise.

Arguments Against the Existence of God

Even granting that there is a universal natural knowledge of God, there are unquestionably people who deny God’s existence and offer arguments in their defense. Some have attempted to exposed contradictions within the concept of God (e.g., between omniscience and divine freedom) thereby likening God to a “square circle” whose existence is logically impossible. At most such arguments only rule out certain conceptions of God, conceptions that are often at odds with the biblical view of God in any case.

A less ambitious approach is to place the burden of proof on the theist: in the absence of good arguments for God’s existence, one ought to adopt the “default” position of atheism (or at least agnosticism). This stance is hard to maintain given the many impressive theistic arguments championed by Christian philosophers today, not to mention the Reformed epistemologists’ argument that belief in God is properly basic.

The most popular atheistic argument is undoubtedly the argument from evil. The strong version of the argument maintains that the existence of evil is logically incompatible with the existence of an all-good, all-powerful God. The more modest version contends that particularly horrifying and seemingly gratuitous instances of evil, such as the Holocaust, provide strong evidence against God’s existence. The problem of evil has invited various theodicies : attempts to explain how God can be morally justified in permitting the evils we encounter in the world. While such explanations can be useful, they aren’t strictly necessary for rebutting the argument from evil. It is enough to point out that given the complexities of the world and the considerable limitations of human knowledge, we are in no position to conclude that God couldn’t have morally justifying reasons for allowing the evils we observe. Indeed, if we already have grounds for believing in God, we can reasonably conclude that God must have such reasons, whether or not we can discern them.

Unit 2: Metaphysics

Aquinas’s Five Proofs for the Existence of God

St. Mary's Press

The Summa Theologica is a famous work written by Saint Thomas Aquinas between AD 1265 and 1274. It is divided into three main parts and covers all of the core theological teachings of Aquinas’s time. One of the questions the Summa Theologica is well known for addressing is the question of the existence of God. Aquinas responds to this question by offering the following five proofs:

1. The Argument from Motion: Our senses can perceive motion by seeing that things act on one another. Whatever moves is moved by something else. Consequently, there must be a First Mover that creates this chain reaction of motions. This is God. God sets all things in motion and gives them their potential.

2. The Argument from Efficient Cause: Because nothing can cause itself, everything must have a cause or something that creates an effect on another thing. Without a first cause, there would be no others. Therefore, the First Cause is God.

3. The Argument from Necessary Being: Because objects in the world come into existence and pass out of it, it is possible for those objects to exist or not exist at any particular time. However, nothing can come from nothing. This means something must exist at all times. This is God.

4. The Argument from Gradation: There are different degrees of goodness in different things. Following the “Great Chain of Being,” which states there is a gradual increase in complexity, created objects move from unformed inorganic matter to biologically complex organisms. Therefore, there must be a being of the highest form of good. This perfect being is God.

5. The Argument from Design: All things have an order or arrangement that leads them to a particular goal. Because the order of the universe cannot be the result of chance, design and purpose must be at work. This implies divine intelligence on the part of the designer. This is God.

Moral Arguments for the Existence of God

Moral arguments for God’s existence form a diverse family of arguments that reason from some feature of morality or the moral life to the existence of God, usually understood as a morally good creator of the universe. Moral arguments are both important and interesting. They are interesting because evaluating their soundness requires attention to practically every important philosophical issue dealt with in metaethics. They are important because of their prominence in popular apologetic arguments for religious belief. Evidence for this can be found in the amazing popularity of C. S. Lewis’s Mere Christianity (1952), which is almost certainly the best-selling book of apologetics in the twentieth century, and which begins with a moral argument for God’s existence. Many ordinary people regard religion as in some way providing a basis or foundation for morality. This fact might seem to favor religious arguments for morality rather than moral arguments for religious belief, but if someone believes that morality is in some way “objective” or “real,” and that this moral reality requires explanation, moral arguments for God’s reality naturally suggest themselves. The apparent connection between morality and religion appears to many people to support the claim that moral truths require a religious foundation, or can best be explained by God’s existence, or some qualities or actions of God.

After some general comments about theistic arguments and a brief history of moral arguments, this essay will discuss several different forms of the moral argument. A major distinction is that between moral arguments that are theoretical in nature and practical or pragmatic arguments. The former are best thought of as arguments that begin with alleged moral facts and argue that God is necessary to explain those facts, or at least that God provides a better explanation of them than secular accounts can offer. The latter typically begin with claims about some good or end that morality requires and argue that this end is not attainable unless God exists. Whether this distinction is hard and fast will be one of the questions to be discussed, as some argue that practical arguments by themselves cannot be the basis of rational belief. To meet such concerns practical arguments may have to include a theoretical dimension as well.

1. The Goals of Theistic Arguments

Before attempting to explain and assess moral arguments for the existence of God, it would be helpful to have some perspective on the goals of arguments for God’s existence. (We shall generically term arguments for God’s existence “theistic arguments.”) Of course views about this are diverse, but most contemporary proponents of such arguments do not see theistic arguments as attempted “proofs,” in the sense that they are supposed to provide valid arguments with premises that no reasonable person could deny. Such a standard of achievement would clearly be setting the bar for success very high, and proponents of theistic arguments rightly note that philosophical arguments for interesting conclusions in any field outside of formal logic hardly ever reach such a standard.

More reasonable questions to ask about theistic arguments would seem to be the following: Are there valid arguments for the conclusion that God exists that have premises that are known or reasonably believed by some people? Are the premises of such arguments more reasonable than their denials, at least for some reasonable people? Arguments that meet these standards could have value in making belief in God reasonable for some people, or even giving some people knowledge of God’s existence, even if it turns out that some of the premises of the arguments can be reasonably denied by other people, and thus that the arguments fail as proofs.

A major issue that cannot be settled here concerns the question of where the burden of proof lies with respect to theistic arguments. Many secular philosophers follow Antony Flew (1976) in holding that there is a “presumption of atheism.” On this view, believing in God is like believing in the Loch Ness Monster or leprechauns, something that reasonable people do not do without sufficient evidence. If such evidence is lacking, the proper stance is atheism rather than agnosticism.

This “presumption of atheism” has been challenged in a number of ways. Alvin Plantinga (2000) has argued that reasonable belief in God does not have to be based on propositional evidence, but can be “properly basic.” On this view, reasonable belief in God can be the outcome of a basic faculty (called the sensus divinitatis by theologian John Calvin) and thus needs no support from arguments at all. In response some would argue that even if theistic belief is not grounded in propositional evidence, it still might require non-propositional evidence (such as experience), so it is not clear that Plantinga’s view by itself removes the burden of proof challenge.

A second way to challenge the presumption of atheism is to question an implicit assumption made by those who defend such a presumption, which is that belief in God is epistemologically more risky than unbelief. The assumption might be defended in the following way: One might think that theists and atheists share a belief in many entities: atoms, middle-sized physical objects, animals, and stars, for example. Someone, however, who believes in leprechauns or sea monsters in addition to these commonly accepted objects thereby incurs a burden of proof. Such a person believes in “one additional thing” and thus seems to incur additional epistemological risk. One might think that belief in God is relevantly like belief in a leprechaun or sea monster, and thus that the theist also bears an additional burden of proof. Without good evidence in favor of belief in God the safe option is to refrain from belief.

However, the theist may hold that this account does not accurately represent the situation. Instead, the theist may argue that the debate between atheism and theism is not simply an argument about whether “one more thing” exists in the world. In fact, God is not to be understood as an entity in the world at all; any such entity would by definition not be God. The debate is rather a debate about the character of the universe. The theist believes that every object in the natural world exists because God creates and conserves that object; every finite thing has the character of being dependent on God. The atheist denies this and affirms that the basic entities in the natural world have the character of existing “on their own.”

If this is the right way to think about the debate, then it is not obvious that atheism is safer than theism. The debate is not about the existence of one object, but the character of the universe as a whole. Both parties are making claims about the character of everything in the natural world, and both claims seem risky. This point is especially important in dealing with moral arguments for theism, since one of the questions raised by such arguments is the adequacy of a naturalistic worldview in explaining morality. Such accounts need to explain without watering the categories of morality down or otherwise domesticating them and thereby depriving them of their most interesting features. Evidentialists may properly ask about the evidence for theism, but it also seems proper to ask about the evidence for atheism if the atheist is committed to a rival metaphysic such as naturalism.

Something that resembles a moral argument for God’s existence, or at least an argument from value, can be found in the fourth of Thomas Aquinas’s “Five Ways” (Aquinas 1265–1274, I, 1, 3). Aquinas there begins with the claim that among beings who possess such qualities as “good, true, and noble” there are gradations. Presumably he means that some things that are good are better than other good things; perhaps some noble people are nobler than others who are noble. In effect Aquinas is claiming that when we “grade” things in this way we are, at least implicitly, comparing them to some absolute standard. Aquinas believes this standard cannot be merely “ideal” or “hypothetical,” and thus this gradation is only possible if there is some being which has this quality to a “maximum” extent: “so that there is something which is truest, something best, something noblest and, consequently, something which is uttermost being; for those things that are greatest in truth are greatest in being, as it is written in Metaph. Ii.” Aquinas goes on to affirm that this being which provides the standard is also the cause or explanation of the existence of these qualities, and such a cause must be God. Obviously, this argument draws deeply on Platonic and Aristotelian assumptions that are no longer widely held by philosophers. For the argument to be plausible today, such assumptions would have to be defended, or else the argument reformulated in a way that frees it from its original metaphysical home.

Probably the most influential versions of the moral argument for belief in God can be traced to Kant (1788 [1956]), who famously argued that the theoretical arguments for God’s existence were unsuccessful, but presented a rational argument for belief in God as a “postulate of practical reason.” Kant held that a rational, moral being must necessarily will “the highest good,” which consists of a world in which people are both morally good and happy, and in which moral virtue is the condition for happiness. The latter condition implies that this end must be sought solely by moral action. However, Kant held that a person cannot rationally will such an end without believing that moral actions can successfully achieve such an end, and this requires a belief that the causal structure of nature is conducive to the achievement of this end by moral means. This is equivalent to belief in God, a moral being who is ultimately responsible for the character of the natural world. Kant’s arguments will be discussed later in this article.

Kant-inspired arguments were prominent in the nineteenth century, and continued to be important right up to the middle of the twentieth century. Such arguments can be found, for example, in W. R. Sorley (1918), Hastings Rashdall (1920), and A. E. Taylor (1945/1930). Although Henry Sidgwick was not himself a proponent of a moral argument for God’s existence, some have argued that his thought presents the materials for such an argument (see Walls and Baggett 2011). In the nineteenth century John Henry Newman (1870) also made good use of a moral argument in his case for belief in God, developing what could be called an argument from conscience.

Besides those luminaries from the history of the moral argument, several other figures made contributions of various sorts to the discussion, including Arthur Balfour (1915), Andrew Seth Pringle-Pattison (1920), Clement Webb (2012), W. G. de Burgh (1938), W. R. Matthews (1921), Austin Farrer (2012), and H. P. Owen (1965). A chronicle of much of this history was published by Walls and Baggett (2019). Recovering such history is a helpful antidote to the ahistorical character of much contemporary analytic philosophy.

In recent philosophy there has been a revival of divine command metaethical theories, which has in turn led to new versions of the moral argument found in such thinkers as Robert Adams (1987), John Hare (1996), and C. Stephen Evans (2010). Work on divine command theory, both in favor and against, has experienced a recent resurgence of interest. This work has encompassed both motivations for and formulations of divine command theory, as well as extensive discussion of both old and new objections to it.

However, it is important to see that there are versions of the moral argument for God’s existence that are completely independent of such a divine command theory, and this possibility can be seen in arguments developed by Angus Ritchie (2012) and Mark Linville (2009). Perhaps the most extensive and developed account of a moral argument for God’s existence in recent philosophy is found in David Baggett and Jerry L. Walls (2016). This book examines a comprehensive cumulative form of moral argument and extensively explores underlying issues. It goes without saying that these renewed arguments have engendered new criticisms as well. Theoretical moral arguments for God’s existence can be understood as variations on the following template:

  • There are objective moral facts.
  • God provides the best explanation of the existence of objective moral facts.
  • Therefore, (probably) God exists.

As we shall see, there are a variety of features of morality that can be appealed to in the first steps of the arguments, as well as a variety of ways in which God might be thought to provide an explanation of those features in the second steps. The use of the somewhat vague phrase “objective moral facts” is intended to allow for this variety in Premise 1. The similarly vague notion of God providing the best explanation of such facts allows for the variety of ways moral features may depend on God—divine commands one salient option among them. Both types of premises are obviously open to challenge. For example, the first premise of such an argument can be challenged by popular metaethical views that see morality as “subjective,” or “expressive,” rather than something that consists of objective facts. Moral skeptics and “error theorists” also challenge the first premise. The second premise can be challenged on the basis of rival explanations of the features of morality, explanations that do not require God. Arguments about the second premise then may require comparison between theistic explanations of morality and these rival views, with an attentive eye on the relevant evidence in need of explanation.

It is easy to see then that the proponent of a moral argument has a complex task: She must defend the reality and objectivity of the feature of morality appealed to, but also defend the claim that this feature can be best explained by God. The second part of the task may require not only demonstrating the strengths of a theistic explanation, but pointing out weaknesses in rival secular explanations as well. Both parts of the task are essential, but it is worth noting that the two components cannot be accomplished simultaneously. The theist must defend the reality of morality against subjectivists, constructivists, and “moral nihilists.” Assuming that this task has been carried out, the theist must then try to show that morality thus understood requires or at least is most plausibly understood by a theistic explanation.

It is interesting to observe, however, that with respect to both parts of the task, the theist may enlist non-theists as allies. The theist may well make common cause with ethical naturalists as well as ethical non-naturalists in defending moral realism against “projective” theories such as expressivism. However, the theist may also enlist the support of error theorists such as J. L. Mackie (1977), and moral nihilists such as Friedrich Nietzsche (1887) in arguing that God is necessary for objective morality. Nietzsche, for example, explicitly holds that God does not exist, but also claims that God’s non-existence undermines the reality of traditional western morality. The fact that theists can enlist such unlikely allies does not mean the moral argument for God’s existence is sound, but it does suggest that the argument is not obviously question-begging, since both premises are sometimes accepted by (different) non-believers.

One easily understandable version of a theistic moral argument relies on an analogy between human laws promulgated by nation-states and moral laws. Sovereign states enact laws that make certain acts forbidden or required. If I am a U. S. citizen, and I earn more than a small amount of money I am obligated to file an income tax return each year. I am also forbidden, because of the laws that hold in the United States, to discriminate in hiring on the basis of sex, age, or race. Many people believe that there are moral laws that bind individuals in the same way that political laws do. I am obligated by a moral principle not to lie to others, and I am similarly obligated to keep promises that I have made. (Both legal and moral laws may be understood as holding prima facie , so that in some situations a person must violate one law in order to obey a more important one.)

We know how human laws come into existence. They are enacted by legislatures (or absolute monarchs in some countries) who have the authority to pass such laws. How then should the existence of moral laws be explained? It seems plausible to many to hold that they must be similarly grounded in some appropriate authority, and the or best candidate to fulfill this role is God. Some philosophers have dismissed an argument of this type as “crude,” presumably because its force is so obvious that no special philosophical training is necessary to understand it and see its appeal. The fact that one can understand the argument without much in the way of philosophical skill is not necessarily a defect, however. If one supposes that there is a God, and that God wants humans to know him and relate to him, one would expect God to make his reality known to humans in very obvious ways (See Evans 2010). After all, critics of theistic belief, such as J. L. Schellenberg (1993), have argued that the fact that God’s reality is not obvious to those who would like to believe in God is a grave problem. If an awareness of moral obligations is in fact an awareness of God’s commands or divine laws, then the ordinary person who is aware of moral obligations does have a kind of awareness of God. Of course such a person might be aware of God’s laws without realizing that they are God’s laws; she might be aware of God’s commands without being aware of them under that description. The religious apologist might view such a person as already having a kind of de re awareness of God, because a moral obligation is simply an expression of God’s will (or God’s command or motivation, preference or desire).

How can such an awareness be converted into full-fledged belief in God? One way of doing this would be to help the person gain the skills needed to recognize moral laws as what they are, as divine commands or divine laws. If moral laws are experienced, then moral experience could be viewed as a kind of religious experience or at least a proto-religious experience. Perhaps someone who has experience of God in this way does not need a moral argument (or any kind of argument) to have a reasonable belief in God. This may be one instance of the kind of case that Alvin Plantinga (2000) and the “Reformed epistemologists” have in mind when they claim that belief in God can be “properly basic.” It is worth noting then that there could be such a thing as knowledge of God that is rooted in moral experience without that knowledge being the result of a moral argument .

Even if that is the case, however, a moral argument could still play a valuable role. Such an argument might be one way of helping an individual understand that moral obligations are in fact divine commands or laws. Even if it were true that some ordinary people might know that God exists without argument, an argument could be helpful in defending the claim that this is the case. A person might conceivably need an argument for the second-level claim that the person knows God without argument.

In any case a divine command metaethical theory provides the material for such an argument. The revival of divine command theories (DCT) of moral obligation is due mainly to the work of Philip Quinn (1979/1978) and Robert Adams (1999). Adams’ version of a DCT has been particularly influential and is well-suited for the defense of the claim that moral knowledge can provide knowledge of God. Adams’ version of a DCT is an account of moral obligations and it must be distinguished from more general “voluntarist” views of ethics that try to treat other moral properties (such as the good) as dependent on God’s will. As explained below, by limiting the theory to obligations, Adams avoids the standard “ Euthyphro ” objection, which claims that divine command views reduce ethics to arbitrariness.

Adams’ account of moral obligations as divine commands rests on a more general social theory of obligations. There are of course many types of obligations: legal obligations, financial obligations, obligations of etiquette, and obligations that hold in virtue of belonging to some club or association, to name just a few. Clearly these obligations are distinct from moral obligations, since in some cases moral obligations can conflict with these other kinds. What is distinctive about obligations in general? They are not reducible simply to normative claims about what a person has a good reason to do.

J. S. Mill (1874, 164–165) argued that we can explain normative principles without making any reference to God. He contends that the “feeling of obligation” stems from “something that the internal conscience bears witness to in its own nature,” and thus the moral law, unlike human laws, “does not originate in the will of a legislator or legislature external to the mind.” Doubtless Mill had in mind here such normative logical principles as “it is wrong to believe both p and not-p at the same time.” Mill argues that such normative principles hold without any requirement for an “authority” to be their ground, and he thinks this is plausible for the case of moral principles as well. Mill’s view is plausible at least for some normative principles, though some theists have argued that metaphysical naturalists have difficulty in explaining any kind of normativity (see Devine 1989, 88–89). However, even if Mill is correct about normativity in general, it does not follow that his view is correct for moral obligations, which have a special character. An obligation has a special kind of force; we should care about complying with it, and violations of obligations appropriately incur blame (Adams 1999, 235). If I make a logical mistake, I may feel silly or stupid or embarrassed, but I have no reason to feel guilty, unless the mistake reflects some carelessness on my part that itself constitutes a violation of a moral obligation. Adams argues that “facts of obligation are constituted by broadly social requirements.” (ibid, 233) For example, the social role of parenting is partly constituted by the obligations one assumes by becoming a parent, and the social role of citizen is partly constituted by the obligations to obey the laws of the country in which one is a citizen.

All obligations are then constituted by social requirements, according to Adams. However, not all obligations constituted by social requirements are moral obligations. What social relation could be the basis of moral obligations? Adams argues that not just any human social relation will possess the requisite authority: “A morally valid obligation obviously will not be constituted by just any demand sponsored by a system of social relationships that one in fact values. Some such demands have no moral force, and some social systems are downright evil.” (ibid, 242) If a good and loving God exists and has created all humans, then the social relation humans have to God has the right features to explain moral obligations. For if moral obligations stem from God’s requirements, they will be objective, but they will also be motivating, since a relation to God would clearly be a great good that humans would have reason to value. Since a proper relation to God is arguably more important than any other social relation, we can also understand why moral obligations trump other kinds of obligations. On this view we can also explain why moral obligations have a transcendent character, which is important because “a genuinely moral conception of obligation must have resources for moral criticism of social systems and their demands.” (ibid, 242–243)

Notice that the DCT Adams defends in his later work is ontological rather than semantic: it is a claim that moral obligations are in fact identical with divine commands, not a claim that “moral obligations” has the same meaning as “divine commands.” On his account, applying the work of direct reference theorists like Hilary Putnam and Saul Kripke to the arena of ethics, the meaning of “moral obligation” is fixed by the role this concept plays in our language. That role includes such facts as these: Moral obligations must be motivating and objective. They also must provide a basis for critical evaluation of other types of obligations, and they must be such that someone who violates a moral obligation is appropriately subject to blame. Adams argues that it is divine commands that best satisfy these desiderata. God’s existence thus provides the best explanation of moral obligations. If moral obligations are identical with divine commands (or perhaps if they are grounded in or caused to exist by divine commands) an argument for God’s existence from such obligations can easily be constructed:

  • There are objective moral obligations.
  • If there are objective moral obligations, there is a God who explains these obligations.
  • There is a God.

This argument is stated in a deductive form, but it can easily be reworded as a probabilistic “argument to the best explanation,” as follows:

  • God provides the best explanation of the existence of moral obligations.
  • Probably, God exists.

Obviously, those who do not find a DCT convincing will not think this argument from moral obligation has force. However, Adams anticipates and gives a forceful answer to one common criticism of a DCT. It is often argued that a DCT must fail because of a dilemma parallel to one derived from Plato’s Euthyphro . The dilemma for a DCT can be derived from the following question: Assuming that God commands what is right, does he command what is right because it is right (assuming that “right” here means “morally required” and not just “morally permissible.”)? If the proponent of a DCT answers affirmatively, then it appears the quality of rightness must hold antecedently to and thus independently of God’s commands. If, however, the proponent denies that God commands what is right because it is right, then God’s commands appear arbitrary. Adams’ version of a DCT evades this dilemma by invoking the good/right distinction and holding that God is essentially good and that his commands are necessarily aimed at the good. This allows Adams to claim that God’s commands make actions obligatory (or forbidden), while denying that the commands are arbitrary in any problematic sense.

Although Adams’ version of a DCT successfully meets this “ Euthyphro ” objection, there are other powerful criticisms that have been mounted against this metaethical theory in the literature. These objections can be found in the writings of Wes Morriston (2009, 2016), Erik Wielenberg (2005, especially part 3, 2014, and chapter 2, 2020), Oppy (2014, especially ch. 3), and Nicholas Wolterstorff (2007), among others. Besides arbitrariness, objections raised against DCT include autonomy objections, a variety of epistemic objections, a psychopathy objection, supervenience objections, prior obligations objection, and other Euthyphro objections, which include grounding, vacuity, and counterpossible objections.

Wielenberg explicitly defends as an alternative to divine command metaethics a view he calls “godless normative realism.” This is essentially the view that moral truths are basic or fundamental in character, not derived from natural facts or any more fundamental metaphysical facts. It thus seems similar to the view often called “ethical non-naturalism.” This view certainly provides a significant alternative to divine command metaethics. However, it is worth noting that some of the criticisms that metaphysical naturalists have against theistic metaethics may apply to Wielenberg’s view as well. Specifically, philosophers such as J. L. Mackie (1977) find non-natural ethical qualities of any kind “queer” since they are so unlike the realities discovered by science. The “brute moral facts” posited by Wielenberg as necessary truths seem vulnerable to this same criticism. In fact, the criticism may be sharper against Wielenberg’s view than against theistic views, since ethical truths may appear less odd in a universe that is ultimately grounded in a person. Responses to the objections of Wielenberg, Morriston, and others have also been given (see Evans 2013, Baggett and Walls, 2011, 2016, Flannagan, 2017, 2021a, 2021, Pruss, 2009, Davis and Franks, 2015). Clearly the version of a moral argument for God’s existence that rests on divine command theory will only be judged powerful by those who find a DCT plausible, and that will certainly be a minority of philosophers. (Although it is worth noting that no single metaethical theory seems to enjoy widespread support among philosophers, so a DCT is not alone in being a minority view.) Nevertheless, those who do find a DCT powerful will also see moral obligations as providing strong evidence for God’s reality.

A variety of arguments have been developed that God is necessary to explain human awareness of moral truth (or moral knowledge, if one believes that this moral awareness amounts to knowledge). Richard Swinburne (2004, 218), for example, argues that there is no “great probability that moral awareness will occur in a Godless universe.” On Swinburne’s view, moral truths are either necessary truths or contingent truths that are grounded in necessary truths. For example, it is obviously contingent that “It is wrong to drop an atomic bomb on Hiroshima,” since it is contingent that there exists a city such as Hiroshima. But one might hold that this proposition is true (assuming it is) because of some other truth such as “It is wrong intentionally to kill innocent humans” which does hold universally and is necessarily true. Swinburne does not think that an argument to God’s existence from moral facts as such is powerful, increasing the likelihood of theism only a little. However, the fact that we humans are aware of moral facts is itself surprising and calls for an explanation.

It may be true that creatures who belong to groups that behave altruistically will have some survival advantage over groups that lack such a trait. However, moral beliefs are not required in order to produce such behavior, since it is clear that “there are many species of animals that are naturally inclined to help others of their species, and yet do not have moral beliefs.” (Swinburne 2004, 217) If God exists, he has “significant reason to bring about conscious beings with moral awareness,” since his intended purpose for humans includes making it possible for them freely to choose good over evil, since this will make it possible for them to develop a relation to God. Swinburne does not think that this argument provides very strong evidence for God’s existence by itself, but rather that it provides some inductive support for belief in God. It is one of several phenomena which seem more probable in a theistic universe than in a godless universe. As we consider more and more such phenomena, it will be increasingly improbable that “they will all occur.” (ibid, 218) All of these inductive arguments together may then provide substantial support for theistic belief, even if no one of them by itself would be sufficient for rational belief by demonstrating that theism is likely true.

Swinburne’s version of the argument is quite brief and undeveloped, but some claims that could be used to support a more developed version of the argument (one that will be described below) can be found in a well-known and much cited article by Sharon Street (2006). Street’s argument, as the title implies, is in no way intended to support a moral argument for theism. To the contrary, her purpose is to defend anti-realist metaethical theories against realist theories that view moral truth as “stance-independent” of human attitudes and emotions. Street presents the moral realist with a dilemma posed by the question as to how our human evaluative beliefs are related to human evolution. It is clear, she believes, that evolution has strongly shaped our evaluative attitudes. The question concerns how those attitudes are related to the objective evaluative truths accepted by the realist. If the realist holds that there is no relation between such truths and our evaluative attitudes, then this implies that “most of our evaluative judgments are off track due to the distorting influence of Darwinian processes.” The other alternative for the realist is to claim that there is a relationship, and thus that is not an accident or miracle that our evaluative beliefs track the objective truths. However, this view, Street claims, is scientifically implausible. Street argues therefore that an evolutionary story about how we came to make the moral judgments we make undermines confidence in the objective truth of those judgments. Street’s argument is of course controversial and thinkers such as Erik Wielenberg (2014) have argued against evolutionary debunking arguments. Still, many regard such arguments as problematic for those who want to defend moral realism, particularly when developed as a “global” argument (Kahane, 2010).

Street’s argument has also been challenged by such critics as Russ Shafer-Landau (2012). However, her argument, and similar arguments, have been acknowledged by some moral realists, such as David Enoch (2011) and Erik Wielenberg (2014) to pose a significant problem for their view. Enoch, for example, even though he offers a response to Street’s argument, evidently has some worries about the strength of his reply. Wielenberg, to avoid the criticism that in a non-theistic universe it would be extremely lucky if evolution selected for belief in objectively true moral values, proposes that the natural laws that produce this result may be metaphysically necessary, and thus there is no element of luck. However, many philosophers will see this view of natural laws as paying a heavy price to avoid theism. It might appear that Street is arguing straightforwardly that evolutionary theory makes it improbable that humans would have objective moral knowledge. However, it is not evolution by itself that predicts the improbability of objective moral knowledge, but the conjunction of evolution and metaphysical naturalism. A good deal of the force of Street’s argument stems from the assumption that naturalism is true, and therefore that the evolutionary process is one that is unguided. Since it is not evolution by itself that poses a challenge to moral realism but the conjunction of evolution and metaphysical naturalism, then rejecting naturalism provides one way for the moral realist to solve the problem. It does appear that in a naturalistic universe we would expect a process of Darwinian evolution to select for a propensity for moral judgments that track survival and not objective moral truths. Mark Linville (2009, 391–446) has developed a detailed argument for the claim that it is difficult for metaphysical naturalists to develop a plausible evolutionary story as to how our moral judgments could have epistemological warrant. However, if we suppose that the evolutionary process has been guided by God, who has as one of his goals the creation of morally significant human creatures capable of enjoying a relation with God, then it would not seem at all accidental or even unlikely that God would ensure that humans have value beliefs that are largely correct.

Some philosophers believe that the randomness of Darwinian natural selection rules out the possibility of any kind of divine guidance being exercised through such a process. Some thinkers, including both some atheists and some proponents of what is called “creation science,” believe that evolution and God are rivals, mutually exclusive hypotheses about the origins of the natural world. What can be explained scientifically needs no religious explanation. However, this is far from obviously true; in fact, if theism is true it is clearly false. From a theistic perspective to think that God and science provide competing explanations fails to grasp the relationship between God and the natural world by conceiving of God as one more cause within that natural world. If God exists at all, God is not an entity within the natural world, but the creator of that natural world, with all of its causal processes. If God exists, God is the reason why there is a natural world and the reason for the existence of the causal processes of the natural world. In principle, therefore, a natural explanation can never preclude a theistic explanation. Any argument that natural explanations preclude or are in tension with theistic explanations will in fact be theological in character, since they will be grounded in assumptions about the kind of world God would create.

But what about the randomness that is a crucial part of the Darwinian story? The atheist might claim that because evolutionary theory posits that the process by which plants and animals have evolved is one that involves random genetic mutations, it cannot be guided, and thus God cannot have used evolutionary means to achieve his ends. However, this argument fails. It depends on an equivocation in what is meant by “random.” When scientists claim that genetic mutations are random, they do not mean that they are uncaused, or even that they are unpredictable from the point of view of biochemistry, but only that the mutations do not happen in response to the adaptational needs of the organism. It is entirely possible for a natural process to include randomness in that sense, even if the whole natural order is itself created and sustained by God. The sense of “randomness” required for evolutionary theory does not imply that the evolutionary process must be unguided. A God who is responsible for the laws of nature and the initial conditions that shape the evolutionary process could certainly ensure that the process achieved certain ends.

Like the other moral arguments for God’s existence, the argument from moral knowledge can easily be stated in a propositional form, and I believe Swinburne is right to hold that the argument is best construed as a probabilistic argument that appeals to God as providing a better explanation of moral knowledge than is possible in a naturalistic universe.

  • Humans possess objective moral knowledge.
  • Probably, if God does not exist, humans would not possess objective moral knowledge.

There is a kind of argument from moral knowledge also implicit in Angus Ritchie’s book From Morality to Metaphysics: The Theistic Implications of our Ethical Commitments (2012). Ritchie presses a kind of dilemma on non-theistic accounts of morality. Subjectivist theories such as expressivism can certainly make sense of the fact that we make the ethical judgments we do, but they empty morality of its objective authority. Objectivist theories that take morality seriously, however, have difficulty explaining our capacity to make true moral judgments, unless the process by which humans came to hold these capacities is one that is controlled by a being such as God.

The moral argument from knowledge will not be convincing to anyone who is committed to any form of expressivism or other non-objective metaethical theory, and clearly many philosophers find such views attractive. And there will surely be many philosophers who will judge that if moral objectivism implies theism or requires theism to be plausible, this is a reductio of objectivist views. Furthermore, non-theistic moral philosophers, whether naturalists or non-naturalists, have stories to tell about how moral knowledge might be possible. Nevertheless, there are real questions about the plausibility of these stories, and thus, some of those convinced that moral realism is true may judge that moral knowledge provides some support for theistic belief.

Many philosophers find Immanuel Kant’s moral philosophy still offers a fruitful approach to ethics. Of the various forms of the “categorical imperative” that Kant offers, the formula that regards human beings as “ends in themselves” is especially attractive: “Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means, but always at the same time as an end” (Kant 1785 [1964], 96). Many contemporary moral philosophers influenced by Kant, such as Christine Korsgaard (1996), see Kant as offering a “constructivist” metaethical position. Constructivism is supposed to offer a “third way” between moral realism and subjectivist views of morality. Like subjectivists, constructivists want to see morality as a human creation. However, like moral realists constructivists want to see moral questions as having objective answers. Constructivism is an attempt to develop an objective morality that is free of the metaphysical commitments of moral realism.

It is, however, controversial whether Kant himself was a constructivist in this sense. One reason to question whether this is the right way to read Kant follows from the fact that Kant himself did not see morality as free from metaphysical commitments. For example, Kant thought that it would be impossible for someone who believed that mechanistic determinism was the literal truth about himself to believe that he was a moral agent, since morality requires an autonomy that is incompatible with determinism. To see myself as a creature who has the kind of value Kant calls “dignity” I must not see myself merely as a machine-like product of the physical environment. Hence Kant thought that it was crucial for morality that his Critical Philosophy had shown that the deterministic perspective on humans is simply part of the “phenomenal world” that is the object of scientific knowledge, not the “noumenal reality” that it would be if some kind of scientific realism were the true metaphysical view. When we do science we see ourselves as determined, but science tells us only how the world appears, not how it really is. Recognizing this fact suggests that when Kant posits that humans have this intrinsic value he calls dignity, he is not “constructing” the value humans have, but recognizing the value beings of a certain kind must have. Humans can only have this kind of value if they are a particular kind of creature. Whether Kant himself was a moral realist or not, there are certainly elements in his philosophy that push in a realist direction.

If the claim that human persons have a kind of intrinsic dignity or worth is a true objective principle and if it provides a key foundational principle of morality, it is well worth asking what kinds of metaphysical implications the claim might have. This is the question that Mark Linville (2009, 417–446) pursues in the second moral argument he develops. Linville begins by noting that one could hardly hold that “human persons have intrinsic dignity” could be true if human persons do not exist. Clearly, some metaphysical positions do include a denial of the existence of human persons, such as forms of Absolute Monism which hold that only one Absolute Reality exists. However, it also seems to be the case that some forms of Scientific Naturalism are committed to the denial of “ persons as substantive selves that essentially possess a first-person point of view” (See Dennett 2006, 107). Daniel Dennett, for example, holds that persons will not be part of the ultimately true scientific account of things. Dennett holds that to think of humans as persons is simply to adopt a certain “stance” toward them that he calls the “intentional stance,” but it is clear that the kind of picture of humans we get when we think of them in this way does not correspond with their intrinsic metaphysical properties. It is not clear how systems towards which we adopt an “intentional stance” could be truly autonomous and thus have the kind of value Kant believes human persons have.

The argument from human dignity could be put into propositional form as follows:

  • Human persons have a special kind of intrinsic value that we call dignity.
  • The only (or best) explanation of the fact that humans possess dignity is that they are created by a supremely good God in God’s own image.
  • Probably there is a supremely good God.

A naturalist may want to challenge premise (2) by finding some other strategy to explain human dignity. Michael Martin (2002), for example, has tried to suggest that moral judgments can be analyzed as the feelings of approval or disapproval of a perfectly impartial and informed observer. Linville (2009) objects that it is not clear how the feelings of such an observer could constitute the intrinsic worth of a person, since one would think that intrinsic properties would be non-relational and mind-independent. In any case, Linville notes that a “Euthyphro” problem lurks for such an ideal observer theory, since one would think that such an observer would judge a person to be intrinsically valuable because the person has intrinsic value.

Another strategy that is pursued by constructivists such as Korsgaard is to link the value ascribed to humans to the capacity for rational reflection. The idea is that insofar as I am committed to rational reflection, I must value myself as having this capacity, and consistently value others who have it as well. A similar strategy is found in Wielenberg’s form of ethical non-naturalism, since Wielenberg argues that it is necessarily true that any being with certain reflective capacities will have moral rights (Wielenberg, 2014, chapter 4). It is far from clear that human rationality provides an adequate ground for moral rights, however. Many people believe that young infants and people suffering from dementia still have this intrinsic dignity, but in both cases there is no capacity for rational reflection.

Some support for this criticism of the attempt to see reason as the basis of the value of humans can be found in Nicholas Wolterstorff’s recent work on justice (2007, especially Ch. 8). Wolterstorff in this work defends the claim that there are natural human rights, and that violating such rights is one way of acting unjustly towards a person. Why do humans have such rights? Wolterstorff says these rights are grounded in the basic worth or dignity that humans possess. When I seek to torture or kill an innocent human I am failing to respect this worth. If one asks why we should think humans possess such worth, Wolterstorff argues that the belief that humans have this quality was not only historically produced by Jewish and Christian conceptions of the human person, but even now cannot be defended apart from such a conception. In particular, he argues that attempts to argue that our worth stems from some excellence we possess such as reason will not explain the worth of infants or those with severe brain injuries or dementia.

Does a theistic worldview fare better in explaining the special value of human dignity? In a theistic universe God is himself seen as the supreme good. Indeed, theistic Platonists usually identify God with the Good. If God is himself a person, then this seems to be a commitment to the idea that personhood itself is something that must be intrinsically good. If human persons are made in God’s image, as both Judaism and Christianity affirm, then it would seem to follow that humans do have a kind of intrinsic value, just by way of being the kind of creatures they are.

This argument will of course be found unconvincing to many. Some will deny premise (1), either because they reject moral realism as a metaethical stance, or because they reject the normative claim that humans have any kind of special value or dignity. (Maybe they will even think that such a claim is a form of “speciesism.”). Others will find premise (2) suspect. They may be inclined to agree that human persons have a special dignity, but hold that the source of that dignity can be found in such human qualities as rationality. With respect to the status of infants and those suffering from dementia, the critic might bite the bullet and just accept the fact that human dignity does not extend to them, or else argue that the fact that infants and those suffering mental breakdown are part of a species whose members typically possess rationality merits them a special respect, even if they lack this quality as individuals. Others will find premise (2) doubtful because they find the theistic explanation of dignity unclear. Another alternative is to seek a Constructivist account of dignity, perhaps regarding the special status of humans as something we humans decide to extend to each other. Perhaps the strongest non-theistic alternative would be some form of ethical non-naturalism, in which one simply affirms that the claim that persons have a special dignity is an a priori truth requiring no explanation. In effect this is a decision for a non-theistic form of Platonism.

The proponent of the argument may well agree that claims about the special status of humans are true a priori , and thus also opt for some form of Platonism. However, the proponent of the argument will point out that some necessary truths can be explained by other necessary truths. The theist believes that these truths about the special status of humans tell us something about the kind of universe humans find themselves in. To say that humans are created by God is to say that personhood is not an ephemeral or accidental feature of the universe, because at bottom reality itself is personal (Mavrodes 1986).

As already noted, the most famous and perhaps most influential version of a moral argument for belief in God is found in Immanuel Kant (1788). Kant himself insisted that his argument was not a theoretical argument, but an argument grounded in practical reason. The conclusion of the argument is not “God exists” or “God probably exists” but “I (as a rational, moral agent) ought to believe that God exists.” We shall, however, see that there are some reasons to doubt that practical arguments can be neatly separated from theoretical arguments.

Kant’s version of the argument can be stated in different ways, but perhaps the following captures one plausible interpretation of the argument. Morality is grounded in pure practical reason, and the moral agent must act on the basis of maxims that can be rationally endorsed as universal principles. Moral actions are thus not determined by results or consequences but by the maxims on which they are based. However, all actions, including moral actions, necessarily aim at ends. Kant argues that the end that moral actions aim at is the “highest good,” which is a world in which both moral virtue and happiness are maximized, with happiness contingent on virtue. For Kant “ought implies can,” and so if I have an obligation to seek the highest good, then I must believe that it is possible to achieve such an end. However, I must seek the highest good only by acting in accordance with morality; no shortcuts to happiness are permissible. This seems to require that I believe that acting in accordance with morality will be causally efficacious in achieving the highest good. However, it is reasonable to believe that moral actions will be causally efficacious in this way only if the laws of causality are set up in such a way that these laws are conducive to the efficacy of moral action. Certainly both parts of the highest good seem difficult to achieve. We humans have weaknesses in our character that appear difficult if not impossible to overcome by our own efforts. Furthermore, as creatures we have subjective needs that must be satisfied if we are happy, but we have little empirical reason to think that these needs will be satisfied by moral actions even if we succeeded in becoming virtuous. If a person believes that the natural world is simply a non-moral machine with no moral purposiveness then that person would have no reason to believe that moral action could succeed because there is no a priori reason to think moral action will achieve the highest good and little empirical reason to believe this either. Kant thus concludes that a moral agent must “postulate” the existence of God as a rational presupposition of the moral life.

One problem with this argument is that many will deny that morality requires us to seek the highest good in Kant’s sense. Even if the Kantian highest good seems reasonable as an ideal, some will object that we have no obligation to achieve such a state, but merely to work towards realizing the closest approximation to such a state that is possible (See Adams 1987, 152). Without divine assistance, perhaps perfect virtue is unachievable, but in that case we cannot be obliged to realize such a state if there is no God. Perhaps we cannot hope that happiness will be properly proportioned to virtue in the actual world if God does not exist, but then our obligation can only be to realize as much happiness as can be attained through moral means. Kant would doubtless reject this criticism, since on his view the ends of morality are given directly to pure practical reason a priori , and we are not at liberty to adjust those ends on the basis of empirical beliefs. However, few contemporary philosophers would share Kant’s confident view of reason here, and thus to many the criticism has force. Even Kant admits at one point that full-fledged belief in God is not rationally necessary, since one could conceivably seek the highest good if one merely believes that God’s existence is possible (Kant, 1781–1787, 651).

Another way of interpreting Kant’s argument puts more stress on the connection between an individual’s desire for happiness and the obligation to do what is morally right. Morality requires me to sacrifice my personal happiness if that is necessary to do what is right. Yet it is a psychological fact that humans necessarily desire their own happiness. In such a state it looks as if human moral agents will be torn by what Henry Sidgwick called the “dualism of the practical reason” (1884, 401). Reason both requires humans to seek their own happiness and to sacrifice it. Sidgwick himself noted that only if there is a God can we hope that this dualism will be resolved, so that those who seek to act morally will in the long run also be acting so as to advance their own happiness and well-being. (Interestingly, Sidgwick himself does not endorse this argument, but he clearly sees this problem as part of the appeal of theism.) A contemporary argument similar to this one has been developed by C. Stephen Layman (2002).

The critic of this form of the Kantian argument may reply that Kantian morality sees duty as something that must be done regardless of the consequences, and thus a truly moral person cannot make his or her commitment to morality contingent on the achievement of happiness. From a Kantian point of view, this reply seems right; Kant unequivocally affirms that moral actions must be done for the sake of duty and not from any desire for personal reward. Nevertheless, especially for any philosopher willing to endorse any form of eudaimonism, seeing myself as inevitably sacrificing what I cannot help but desire for the sake of duty does seem problematic. As John Hare affirms, “If we are to endorse wholeheartedly the long-term shape of our lives, we have to see this shape as consistent with our happiness” (1996, 88).

The critic may reply to this by simply accepting the lamentable fact that there is something tragic or even absurd about the human condition. The world may not be the world we wish it was, but that does not give us any reason to believe it is different from what it is. If there is a tension between the demands of morality and self-interest, then this may simply be a brute fact that must be faced.

This reply raises an issue for all forms of practical or pragmatic arguments for belief. Many philosophers insist that rational belief must be grounded solely in theoretical evidence. The fact that it would be better for me to believe p does not in itself give me any reason to believe p. This criticism is aimed not merely at Kant, but at other practical moral arguments. For example, Robert Adams argues that if humans believe there is no moral order to the universe, then they will become demoralized in their pursuit of morality, which is morally undesirable (1987, 151). The atheist might concede that atheism is (somewhat) demoralizing, but deny that this provides any reason to believe there is a moral order to the universe. Similarly, Linda Zagzebski (1987) argues that morality will not be a rational enterprise unless good actions increase the amount of good in the world. However, given that moral actions often involve the sacrifice of happiness, there is no reason to believe moral action will increase the good unless there is a power transcendent of human activity working on the side of the good. Here the atheist may claim that moral action does increase the good because such actions always increase good character. However, even if that reply fails the atheist may again simply admit that there may be something tragic or absurd about the human condition, and the fact that we may wish things were different is not a reason to believe that they are. So the problem must be faced: Are practical arguments merely rationalized wish-fulfillment?

The theist might respond to this kind of worry in several ways. The first thing to be said is that the fact that a naturalistic view of the universe implies that the universe must be tragic or absurd, if correct, would itself be an important and interesting conclusion. However, apart from this, it makes a great deal of difference how one construes what we might call the background epistemic situation. If one believes that our theoretical evidence favors atheism, then it seems plausible to hold that one ought to maintain a naturalistic view, even if it is practically undesirable that the world have such a character. In that case a practical argument for religious belief could be judged a form of wish-fulfillment. However, this does not seem to be the way those who support such a practical argument see the situation. Kant affirms that the limits of reason established in The Critique of Pure Reason would silence all objections to morality and religion “in Socratic fashion, namely, by the clearest proof of the ignorance of the objectors.” (1781, 1787, 30. See also 530–531) In fact, the situation actually favors theism, since Kant holds that theoretical reason sees value in the concept of God as a regulative ideal, even though God’s existence cannot be theoretically affirmed as knowledge. If we appeal to God’s will to explain what happens in the natural order, we undermine both science and religion, since in that case we would no longer seek empirical evidence for causality and we would make God into a finite object in the natural world (1781, 1787, 562–563). However, as a regulative ideal, the concept of God is one that theoretical reason finds useful: “The assumption of a supreme intelligence, as the one and only cause of the universe, though in the idea alone, can therefore always benefit reason and can never injure it” (1781, 1787, 560). There is a sense in which theoretical reason itself inclines towards affirmation of God, because it must assume that reality is rationally knowable: “If one wishes to achieve systematic knowledge of the world, he ought to regard it as if it were created by a supreme reason.” (Kant 1786, 298) Although theoretical reason cannot affirm the existence of God, it finds it useful to think of the natural world as having the kinds of characteristics it would have if God did exist. Thus, if rational grounds for belief in God come from practical reason, theoretical reason will raise no objections.

For Kant the argument from practical reason for belief in God is not a form of wish-fulfillment because its ground is not an arbitrary desire or wish but “a real need associated with reason” (Kant, 1786, 296). Human beings are not purely theoretical spectators of the universe, but agents. It is not always rational or even possible to refrain from action, and yet action presupposes beliefs about the way things are (For a good interpretation and defense of this view of Kant on the relation between action and belief, see Wood 1970, 17–25). Thus, in some cases suspension of judgment is not possible. The critic may object that a person may act as if p were true without believing p. However, it is not clear that this advice to distinguish action on the basis of p and belief that p can always be followed. For one thing, it seems empirically the case that one way of acquiring belief that p is simply to begin to act as if p were true. Hence, to begin to act as if p were true is at least to embark upon a course of action that makes belief in p more likely. Second, there may well be a sense of “belief” in which “acting as if p were true” is sufficient to constitute belief. This is obviously the case on pragmatist accounts of belief. But even those who reject a general pragmatic account of belief may well find something like this appealing with respect to religious belief. Many religious believers hold that the best way to measure a person’s religious faith is in terms of the person’s actions. Thus, a person who is willing to act on the basis of a religious conception, especially if those actions are risky or costly, is truly a religious believer, even if that person is filled with doubt and anxiety. Such a person might well be construed as more truly a believer than a person who smugly “assents” to religious doctrines but is unwilling to act on them.

Perhaps the right way to think of practical moral arguments is not to see them as justifying belief without evidence, but as shifting the amount of evidence seen as necessary. This is the lesson some would draw from the phenomenon of “pragmatic encroachment” that has been much discussed in recent epistemology. Here is an example of pragmatic encroachment:

You: I am about to replace the ceiling fan in the kitchen. Spouse: Did you turn off the main electrical power to the house? You: Yes. Spouse: If you forgot you could electrocute yourself. You: I better go back and check. (See McBrayer 2014, Rizzieri 2013).

A plausible interpretation of this scenario is that ordinarily claims such as the one I made, based on memory, are justified, and count as knowledge. However, in this situation, the stakes are raised because my life is at risk, and my knowledge is lost because the pragmatic situation has “encroached” on the normal truth-oriented conditions for knowledge. Pragmatic encroachment is controversial and the idea of such encroachment is rejected by some epistemologists. However, defenders hold that it is reasonable to consider the pragmatic stakes in considering evidence for a belief that underlies significant action (see Fantl and McGrath 2007). If this is correct, then it seems reasonable to consider the pragmatic situation in determining how much evidence is sufficient to justify religious beliefs. In theory the adjustment could go in either direction, depending on what costs are associated with a mistake and on which side those costs lie.

In any case it is not clear that practical moral arguments can always be clearly distinguished from theoretical moral arguments. The reason this is so is that in many cases the practical situation described seems itself to be or involve a kind of evidence for the truth of the belief being justified. Take, for example, Kant’s classic argument. One thing Kant’s argument does is call to our attention that it would be enormously odd to believe that human beings are moral creatures subject to an objective moral law, but also to believe that the universe that humans inhabit is indifferent to morality. In other words, the existence of human persons understood as moral beings can itself be understood as a piece of evidence about the character of the universe humans find themselves in. Peter Byrne (2013, 1998) has criticized practical arguments on the grounds that they presuppose something like the following proposition: “The world is likely to be organized so as to meet our deepest human needs.” Byrne objects that this premise is likely to be false if there is no God and thus arguments that assume it appear circular. However, it is not clear that only those who already believe in God will find this premise attractive. The reason for this is that humans are themselves part of the natural universe, and it seems a desirable feature of a metaphysical view that it explain (rather than explain away) features of human existence that seem real and important.

It seems likely therefore that any appeal to a practical argument will include some theoretical component as well, even if that component is not always made explicit. Nevertheless, this does not mean that practical arguments do not have some important and distinctive features. For Kant it was important that religious beliefs stem from practical reason. For if religious belief were grounded solely in theoretical reason, then such belief would have to conform to “extrinsic and arbitrary legislation.” (Kant 1790, 131) Kant thinks such a religion would be one grounded in “fear and submission,” and thus it is good that religious belief is motivated mainly by a free moral act by which the “final end of our being” is presented to us. (1790, 159) For any practical argument makes religious belief existential; the issue is not merely what I believe to be true about the universe but how I shall live my life in that universe.

It seems clear that no version of the moral argument constitutes a “proof” of God’s existence. Each version contains premises that many reasonable thinkers reject. However, this does not mean the arguments have no force. One might think of each version of the argument as attempting to spell out the “cost” of rejecting the conclusion. Some philosophers will certainly be willing to pay the cost, and indeed have independent reasons for doing so. However, it would certainly be interesting and important if one became convinced that atheism required one to reject moral realism altogether, or to embrace an implausible account of how moral knowledge is acquired. For those who think that some version or versions of the arguments have force, the cumulative case for theistic belief may be raised by such arguments.

6.3 Cosmology and the Existence of God

Learning objectives.

By the end of this section, you will be able to:

  • Describe teleological and moral arguments for the existence of God.
  • Outline Hindu cosmology and arguments for and against the divine.
  • Explain Anselm’s ontological argument for the existence of God.
  • Articulate the distinction between the logical and evidential problems of evil.

Another major question in metaphysics relates to cosmology. Cosmology is the study of how reality is ordered. How can we account for the ordering, built upon many different elements such as causation, contingency, motion, and change, that we experience within our reality? The primary focus of cosmological arguments will be on proving a logically necessary first cause to explain the order observed. As discussed in earlier sections, for millennia, peoples have equated the idea of a first mover or cause with the divine that exists in another realm. This section will discuss a variety of arguments for the existence of God as well as how philosophers have reconciled God's existence with the presence of evil in the world.

Teleological Arguments for God

Teleological arguments examine the inherent design within reality and attempt to infer the existence of an entity responsible for the design observed. Teleological arguments consider the level of design found in living organisms, the order displayed on a cosmological scale, and even how the presence of order in general is significant.

Aquinas’s Design Argument

Thomas Aquinas’s Five Ways is known as a teleological argument for the existence of God from the presence of design in experience. Here is one possible formulation of Aquinas’s design argument:

  • Things that lack knowledge tend to act toward an end/goal.
  • It is obvious that it is not by chance.
  • Things that lack knowledge act toward an end by design.
  • If a thing is being directed toward an end, it requires direction by some being endowed with intelligence (e.g. the arrow being directed by the archer).
  • Therefore, some intelligent being exists that directs all natural things toward their end. This being is known as God.

Design Arguments in Biology

Though Aquinas died long ago, his arguments still live on in today’s discourse, exciting passionate argument. Such is the case with design arguments in biology. William Paley (1743–1805) proposed a teleological argument, sometimes called the design argument, that there exists so much intricate detail, design, and purpose in the world that we must suppose a creator. The sophistication and incredible detail we observe in nature could not have occurred by chance.

Paley employs an analogy between design as found within a watch and design as found within the universe to advance his position. Suppose you were walking down a beach and you happened to find a watch. Maybe you were feeling inquisitive, and you opened the watch (it was an old-fashioned pocket watch). You would see all the gears and coils and springs. Maybe you would wind up the watch and observe the design of the watch at work. Considering the way that all the mechanical parts worked together toward the end/goal of telling time, you would be reluctant to say that the watch was not created by a designer.

Now consider another object—say, the complexity of the inner workings of the human eye. If we can suppose a watchmaker for the watch (due to the design of the watch), we must be able to suppose a designer for the eye. For that matter, we must suppose a designer for all the things we observe in nature that exhibit order. Considering the complexity and grandeur of design found in the world around us, the designer must be a Divine designer. That is, there must be a God.

Often, the design argument is formulated as an induction:

  • In all things we have experienced that exhibit design, we have experienced a designer of that artifact.
  • The universe exhibits order and design.
  • Given #1, the universe must have a designer.
  • The designer of the universe is God.

Moral Arguments for God

Another type of argument for the existence of God is built upon metaethics and normative ethics. Consider subjective and objective values. Subjective values are those beliefs that guide and drive behaviors deemed permissible as determined by either an individual or an individual’s culture. Objective values govern morally permissible and desired outcomes that apply to all moral agents. Moral arguments for the existence of God depend upon the existence of objective values.

If there are objective values, then the question of “Whence do these values come?” must be raised. One possible answer used to explain the presence of objective values is that the basis of the values is found in God. Here is one premise/conclusion form of the argument:

  • If objective values exist, there must be a source for their objective validity.
  • The source of all value (including the validity held by objective values) is God.
  • Objective values do exist.
  • Therefore, God exists.

This argument, however, raises questions. Does moral permissibility (i.e., right and wrong) depend upon God? Are ethics an expression of the divine, or are ethics better understood separate from divine authority? To explore this topic further, students will find a helpful overview and updated references in the Stanford Encyclopedia article, " Moral Arguments for the Existence of God ."

Write Like a Philosopher

Watch “ God & Morality: Part 2 ” by Steven Darwall.

Darwall’s argument for the autonomy of ethics may be restated as follows:

  • God knows morality best (1:44).
  • God knows what is best for us (2:12).
  • God has authority over us (2:48).

How does Darwall refute the conclusion? What is the evidence offered, and at what point within the argument is the evidence introduced? What does his approach suggest about refutational strategies? Can you refute Darwall’s argument?

As you write, begin by defining the conclusion. Remember that in philosophy, conclusions are not resting points but mere starting points. Next, present the evidence, both stated and unstated, and explain how it supports the conclusion.

The Ontological Argument for God

An ontological argument for God was proposed by the Italian philosopher, monk, and Archbishop of Canterbury Anselm (1033–1109). Anselm lived in a time where belief in a deity was often assumed. He, as a person and as a prior of an abbey, had experienced and witnessed doubt. To assuage this doubt, Anselm endeavored to prove the existence of God in such an irrefutable way that even the staunchest of nonbelievers would be forced, by reason, to admit the existence of a God.

Anselm’s proof is a priori and does not appeal to empirical or sense data as its basis. Much like a proof in geometry, Anselm is working from a set of “givens” to a set of demonstrable concepts. Anselm begins by defining the most central term in his argument—God. For the purpose of this argument, Anselm suggests, let “God” = “a being than which nothing greater can be conceived.” He makes two key points:

  • When we speak of God (whether we are asserting God is or God is not), we are contemplating an entity who can be defined as “a being than which nothing greater can be conceived.”
  • When we speak of God (either as believer or nonbeliever), we have an intramental understanding of that concept—in other words, the idea is within our understanding.

Anselm continues by examining the difference between that which exists in the mind and that which exists both in the mind and outside of the mind. The question is: Is it greater to exist in the mind alone or in the mind and in reality (or outside of the mind)? Anselm asks you to consider the painter—for example, define which is greater: the reality of a painting as it exists in the mind of an artist or that same painting existing in the mind of that same artist and as a physical piece of art. Anselm contends that the painting, existing both within the mind of the artist and as a real piece of art, is greater than the mere intramental conception of the work.

At this point, a third key point is established:

Have you figured out where Anselm is going with this argument?

  • If God is a being than which nothing greater can be conceived (established in #1 above);
  • And since it is greater to exist in the mind and in reality than in the mind alone (established in #3 above);
  • Then God must exist both in the mind (established in #2 above) and in reality;
  • In short, God must be. God is not merely an intramental concept but an extra-mental reality as well.

Hindu Cosmology

One of the primary arguments for the existence of God as found within Hindu traditions is based on cosmological conditions necessary to explain the reality of karma. As explained in the introduction to philosophy chapter and earlier in this chapter, karma may be thought of as the causal law that links causes to effects. Assuming the doctrine of interdependence, karma asserts that if we act in such a way to cause harm to others, we increase the amount of negativity in nature. We therefore hurt ourself by harming others. As the self moves through rebirth ( samsara ), the karmic debt incurred is retained. Note that positive actions also are retained. The goal is liberation of the soul from the cycle of rebirth.

Maintenance of the Law of Karma

While one can understand karmic causality without an appeal to divinity, how the causal karmic chain is so well-ordered and capable of realizing just results is not as easily explainable without an appeal to divinity. One possible presentation of the argument for the existence of God from karma could therefore read as follows:

  • If karma is, there must be some force/entity that accounts for the appropriateness (justice) of the karmic debt or karmic reward earned.
  • The source responsible for the appropriateness (justice) of the debt or reward earned must be a conscious agent capable of lending order to all karmic interactions (past, present, and future).
  • Karmic appropriateness (justice) does exist.
  • Therefore, a conscious agent capable of lending order to all karmic interactions (past, present, and future) must exist.

Physical World as Manifestation of Divine Consciousness

The cosmology built upon the religious doctrines allows for an argument within Hindu thought that joins a version of the moral argument and the design argument. Unless a divine designer were assumed, the moral and cosmological fabric assumed within the perspective could not be asserted.

Hindu Arguments Against the Existence of God

One of the primary arguments against the existence of God is found in the Mīmāmsā tradition. This ancient school suggests that the Vedas were eternal but without authors. The cosmological and teleological evidence as examined above was deemed inconclusive. The focus of this tradition and its several subtraditions was on living properly.

Problem of Evil

The problem of evil poses a philosophical challenge to the traditional arguments (in particular the design argument) because it implies that the design of the cosmos and the designer of the cosmos are flawed. How can we assert the existence of a caring and benevolent God when there exists so much evil in the world? The glib answer to this question is to say that human moral agents, not God, are the cause of evil. Some philosophers reframe the problem of evil as the problem of suffering to place the stress of the question on the reality of suffering versus moral agency.

The Logical Problem of Evil

David Hume raised arguments not only against the traditional arguments for the existence of God but against most of the foundational ideas of philosophy. Hume, the great skeptic, starts by proposing that if God knows about the suffering and would stop it but cannot stop it, God is not omnipotent. If God is able to stop the suffering and would want to but does not know about it, then God is not omniscient. If God knows about the suffering and is able to stop it but does not wish to assuage the pain, God is not omnibenevolent. At the very least, Hume argues, the existence of evil does not justify a belief in a caring Creator.

The Evidential Problem of Evil

The evidential problem considers the reality of suffering and the probability that if an omnibenevolent divine being existed, then the divine being would not allow such extreme suffering. One of the most formidable presentations of the argument was formulated by William Rowe :

There exist instances of intense suffering which an omnipotent, omniscient being could have prevented without thereby losing some greater good or permitting some evil equally bad or worse. An omniscient, wholly good being would prevent the occurrence of any intense suffering it could, unless it could not do so without thereby losing some greater good or permitting some evil equally bad or worse. (Therefore) there does not exist an omnipotent, omniscient, wholly good being. (Rowe 1979, 336)

Western Theistic Responses to the Problem of Evil

Many theists (those who assert the existence of god/s) have argued against both the logical and evidential formulations of the problem of evil. One of the earliest Christian defenses was authored by Saint Augustine. Based upon a highly Neo-Platonic methodology and ontology, Augustine argued that as God was omnibenevolent (all good), God would not introduce evil into our existence. Evil, observed Augustine, was not real. It was a privation or negation of the good. Evil therefore did not argue against the reality or being of God but was a reflection for the necessity of God. Here we see the application of a set of working principles and the stressing of a priori resulting in what could be labeled ( prima facie ) a counterintuitive result.

An African Perspective on the Problem of Evil

In the above sections, the problem of evil was centered in a conception of a god as all-powerful, all-loving, and all-knowing. Evil, from this perspective, reflects a god doing evil (we might say reflecting the moral agency of a god) and thus results in the aforementioned problem—how could a “good” god do evil or perhaps allow evil to happen? The rich diversity of African thought helps us examine evil and agency from different starting points. What if, for example, the lifting of the agency (the doing of evil) was removed entirely from the supernatural? In much of Western thought, God was understood as the creator. Given the philosophical role and responsibilities that follow from the assignment of “the entity that made all things,” reconciling evil and creation and God as good becomes a problem. But if we were to remove the concept of God from the creator role, the agency of evil (and reconciling evil with the creator) is no longer present.

Within the Yoruba-African perspective, the agency of evil is not put upon human agency, as might be expected in the West, but upon “spiritual beings other than God” (Dasaolu and Oyelakun 2015). These multiple spiritual beings, known as “Ajogun,” are “scattered around the cosmos” and have specific types of wrongdoing associated specifically with each being (Dasaolu and Oyelakun 2015). Moving the framework (or cosmology) upon which goodness and evil is understood results in a significant philosophical shift. The meaning of evil, instead of being packed with religious or supernatural connotations, has a more down-to-earth sense. Evil is not so much sin as a destruction of life. It is not an offense against an eternal Creator, but an action conducted by one human moral agent that harms another human moral agent.

Unlike Augustine’s attempt to explain evil as the negation of good (as not real), the Yoruban metaphysics asserts the necessity of evil. Our ability to contrast good and evil are required logically so that we can make sense of both concepts.

Can God Be Proved Mathematically?

Some mathematicians have sought a logical proof for the existence of God. Here’s what they discovered

By Manon Bischoff

Who would have thought about God as an apt topic for an essay about mathematics? Don’t worry, the following discussion is still solidly grounded within an intelligible scientific framework. But the question of whether God can be proved mathematically is intriguing . In fact, over the centuries, several mathematicians have repeatedly tried to prove the existence of a divine being. They range from Blaise Pascal and René Descartes (in the 17th century) to Gottfried Wilhelm Leibniz (in the 18th century) to Kurt Gödel (in the 20th century), whose writings on the subject were published as recently as 1987. And probably the most amazing thing: in a preprint study first posted in 2013 an algorithmic proof wizard checked Gödel’s logical chain of reasoning—and found it to be undoubtedly correct. Has mathematics now finally disproved the claims of all atheists?

As you probably already suspect, it has not. Gödel was indeed able to prove that the existence of something , which he defined as divine, necessarily follows from certain assumptions. But whether these assumptions are justified can be called into doubt. For example, if I assume that all cats are tricolored and know that tricolored cats are almost always female, then I can conclude: almost all cats are female. Even if the logical reasoning is correct, this of course does not hold. For the very assumption that all cats are tricolored is false. If one makes statements about observable things in our environment, such as cats, one can verify them by scientific investigations. But if it is about the proof of a divine existence, the matter becomes a little more complicated.

While Leibniz, Descartes and Gödel relied on an ontological proof of God in which they deduced the existence of a divine being from the mere possibility of it by logical inference, Pascal (1623–1662) chose a slightly different approach: he analyzed the problem from the point of view of what might be considered today as game theory and developed the so-called Pascal’s wager.

To do this, he considered two possibilities. First, God exists. Second, God does not exist. Then he examined the consequences of believing or not believing in God after death. If there is a divine being, and one believes in it, one ends up in paradise; otherwise one goes to hell. If, on the other hand, there is no God, nothing else happens—regardless of whether you are religious or not. The best strategy, Pascal contends, is to believe in God. At best, you end up in paradise; in the worst scenario, nothing happens at all. If, on the other hand, you don’t believe, then in the worst case you could end up in hell.

Pascal’s thoughts are comprehensible—but they refer to scenarios from religious writings and do not represent a proof for the existence of a superior being. They only say that one should join the faith based on opportunism.

Ontological approaches dealing with the nature of being are more convincing, even if they will most likely not change the minds of atheists. Theologian and philosopher Anselm of Canterbury (1033–1109) put forward his ideas at the beginning of the last millennium. He described God as a being beyond whom nothing greater can be thought. But if God does not exist, then one can imagine something greater: namely, a being beyond which nothing greater can be contemplated. But like God, this being also exists and exhibits a property of ultimate greatness. This, of course, is absurd: nothing can be greater than the greatest thing that one can imagine. Accordingly, the assumption that God does not exist must be wrong.

It took a few centuries for this idea to be revisited—by none other than Descartes (1596–1650

) . Supposedly unaware of Anselm’s writings, he provided an almost identical argument for the divine existence of a perfect being. Leibniz (1646–1716) took up the work a few decades later and found fault with it: Descartes, he contended, had not shown that the “perfect properties” of certain entities, ranging from triangles to God, are compatible. Leibniz went on to argue that perfection could not be properly investigated. Therefore, it could never be disproved that perfect properties unite in one being. Thus, the possibility of a divine being must be real. So based on Anselm’s and Descartes’s arguments, it necessarily follows that God exists.

From a mathematical point of view, however, these thought experiments became really serious only through Gödel’s efforts. This is not too surprising: The scientist had already turned the subject on its head at the age of 25 by showing that mathematics always contains true statements that cannot be proved. In doing so, he made use of logic. This same logic also enabled him to prove the existence of God. Take a look at these 12 steps made up of a set of axioms (Ax), theorems (Th) and definitions (Df).

None

Formal proof by Kurt Gödel. Credit: Spektrum der Wissenschaft (detail)

At first glance, they seem cryptic, but one can go through them step by step to follow Gödel’s thinking. He starts with an axiom—an assumption, in other words: If φ has the property P and from φ always follows ψ, then ψ also has the property P. For simplicity, we can assume that P stands for “positive”. For example:, if a fruit is delicious, a positive property, then it is also fun to eat. Therefore, the fun of eating it is also a positive property.

The second axiom further sets a framework for P. If the opposite of something is positive, then that “something” must be negative. Thus, Gödel has divided a world into black and white: Either something is good or bad. For example, if health is good, then a disease must necessarily be bad.

With these two premises, Gödel can derive his first theorem: If φ is a positive property, then there is a possibility that an x with property φ exists. That is, it is possible for positive things to exist.

Now the mathematician turns for the first time to the definition of a divine being: x is divine if it possesses all positive properties φ. The second axiom ensures that a God defined in this way cannot have negative characteristics (otherwise one would create a contradiction).

The third axiom states that divinity is a positive characteristic. This point is not really arguable because divinity combines all positive characteristics.

The second theorem now becomes a bit more concrete: by combining the third axiom (divinity is positive) and the first theorem (there is the possibility that something positive exists), a being x could exist that is divine.

Gödel’s goal now is to show in the following steps that God must necessarily exist in the framework that has been laid out. For this purpose, he introduces in the second definition the “essence” φ of an object x, a characteristic property that determines all other characteristics. An illustrative example is “puppylike if something has this property, it is necessarily cute, fluffy and clumsy.

The fourth axiom doesn’t seem too exciting at first. It simply states that if something is positive, then it is always positive—no matter the time, situation or place. Being puppylike and tasting good, for example, are always positive, whether during the day or at night in Heidelberg, Germany, or Buenos Aires.

Gödel can now formulate the third theorem: if a being x is divine, then divinity is its essential property. This makes sense because if something is divine, it possesses all positive characteristics—and thus the properties of x are fixed.

The next step relates to the existence of a particular being. If somewhere at least one being y possesses the property φ, which is the essential property of x, then x also exists. That is, if anything is puppylike, then puppies must also exist.

According to the fifth axiom, existence is a positive property. I think most people would agree with that.

From this one can now conclude that God exists because this being possesses every positive property, and existence is positive.

As it turns out, Gödel’s logical inferences are all correct—even computers have been able to prove that. Nevertheless, these inferences have also drawn criticism. Besides the axioms, which of course can be questioned (why should a world be divisible into “good” and “evil”?), Gödel does not give more details about what a positive property is.

It’s true that by means of the definitions and axioms, one can describe the set P mathematically:

If a property belongs to the set, its negation is not included. The set is self-contained.

The fact that the essence of the set has only the characteristics of the set is itself an element of the set. The set always has the same elements—independent of the situation. In this case, the situation is the mathematical model in which the set is contained.

Existence is part of the set.

If φ is part of the set, then the property of having φ as the essence of the set is also contained in the set.

But all of this does not ensure that this set is unique. There could be multiple collections that satisfy the requirements. For example, as logicians have shown , it is possible to construct cases where, by Gödel’s definition, there are more than 700 divine entities that differ in essence.

This does not settle the final question of the existence of one (or more) divine beings. Whether mathematics is really the right way to answer this question is itself questionable—even if thinking about it is quite exciting.

Proof of the Existence of God

Profile image of Subhash Kak

This essay summarizes recent arguments in favor of the view that consciousness cannot be derived from material ground, which may be seen as proof of the existence of God.

proof of god's existence essay

Greg Janzen

According to the Judeo-Christian-Islamic theological tradition, or " classical theism, " disembodiment (or non-physicality) and psychologicality are two of God's necessary or essential attributes. This paper mounts a case for the thesis that these attributes are incompatible. More exactly, it provides compelling evidentiary support for the claim that, given the basic structure of consciousness, it is impossible for a psychological being to be disembodied (and vice versa). But if it is impossible for a psychological being to be disembodied (and vice versa), then, since psychologicality and disembodiment are both essential to God under classical theism, the God of classical theism does not – and cannot – exist.

With substance dualism and the existence of God, Swinburne (2004) and Moreland (2010) have argued for a very powerful explanatory mechanism that can readily explain several philosophical problems related to consciousness. However, their positions come with presuppositions and ontological commitments which many are not prepared to share. The aim of this paper is to improve on the Swinburne-Moreland argument from consciousness by developing an argument for the existence of God from consciousness without being committed to substance dualism. The argument proceeds by suggesting a solution to the exceptional-point-of-view problem, i.e., the question how it can be explained that there is a conscious being lucky enough to experience the point of view of a relatively tiny brain amidst a giant universe that is indifferent about which physical entities it brings about according to the laws of physics.

Faith and Philosophy

I provide an argument from consciousness for God’s existence. I first give a form of the argument which ultimately, I think is difficult to evaluate. As such I move on to provide what I take to be a stronger argument, where I claim that consciousness given our worldly laws of nature offers rather substantial evidence for God’s existence. It is this latter point the paper largely focuses on, both in setting it out and defending it from various objections.

Kirsten Birkett

Abstract. Consciousness studies are dogged with religious overtones, and many researchers fight hard against Christian ideas of soul or anything supernatural. This gives many studies on consciousness a particular relevance to religious belief. Many writers assume that, if consciousness can be explained physically, religious belief in a soul—and perhaps religious belief itself—must be false. Theorists of consciousness grapple with questions of materialism and reduction in trying to understand how the physical brain can produce the bizarre sensations that we call ourselves. In this essay I discuss the problems in trying to separate religion from science in such a “fuzzy” area as consciousness. I look at the question of what precisely theories of consciousness are trying to explain. I consider theories from David Chalmers, Daniel Dennett, and Roger Penrose as examples of different approaches. Although all of these are materialistically based, I argue that they do not necessarily demonstrate the nonexistence of a soul and also that religious belief does not necessarily require belief in a nonmaterial soul. I conclude with a discussion of why a physical/ materialist explanation of consciousness is desired and how religious bias is still a problem in this scientific/philosophical field.

Under the panoply that natural science and theology are not mutually exclusive, but opposite ends of a broad spectrum of human epistemology; what constitutes a pragmatic proof of God? The most primitive tool of epistemology, Myth and Superstition, which guided civilization for thousands of years, still exists to a surprising degree in modern cultures. The second tool, Logic and Reason can produce egregiously valid arguments both for and against the existence of God. The third tool of epistemology, empiricism, since Galileo has been the basis of modern experimental science; but the challenge of repeatability remains between objective and subjective modes of measurement and some experiments are deemed impossible to perform. The fourth tool, completing epistemology, transcendence, perhaps had secular origin in the noetic writings of ancient Greek philosopher Plato. It has always been possible to demonstrate the existence of God utilizing this fourth tool of epistemology, but because transcendence is generally subjective; it has not been acceptable by current definitions of pragmatic science or to nonbelievers unwilling/unable to achieve the required state-of-mind. Because of the lack of a rigorous model for a Physics of the Observer, and limitations imposed by the quantum uncertainty principle; the currently available tools of physical science have not allowed an objectively oriented empirical proof of God. This however, changes to an arguable degree with the addition of the 3 rd regime of Natural Science-Unified Field Mechanics (Classical-Quantum-UFM). The Perennial Philosophy promotes the idea that all world religions are based on a single universal truth that promotes spiritual union with God. Stated another way, the Perennial Philosophy says: If there is a God he has provided a way for Man to find him. In this work, we review logical and metaphysical methods of fulfilling this premise; but most saliently provide an empirical protocol that for the first time in history is able to demonstrate the existence of a Life Principle tantamount to the Spirit of God as a physically real noumenon, hidden until now behind the uncertainty principle. Although this represents a major step forward, there remains ineffable properties of the Spirit of God unknowable to a temporal mind; and the subtleties of a new physical UFM noetic action principle will remain engendered with concomitant bias of interpretation in what is demonstrated depending on whether one is inclined or disinclined to believe in the existence of God. Ultimately mystical experience provides the only proof of God.

Evidence of God's Existence

Updated 24 November 2023

Downloads 28

Category Religion

The various animals on land, creatures in waters, birds in the sky, the vast lands separated by huge water bodies, and the ability of man to control them creates an urge to comprehend how the world came to be. This paper aims to prove the existence of God as the Supreme Being. By applying relevant examples and utilizing the moral argument, the article will provide evidence to prove the existence of God.

Morality as a proof of God’s Existence

If it was true that God does not exist, then, there is no objectivity for the existence of moral duties and values. However, the presence of universal moral obligations and principles prove the presence of the Almighty. Currently, individuals from different backgrounds are expected to learn, maintain and uphold specific ethics such as being truthful, honest, just, incorrupt, generous, faithful, and obedient. Also, they have a duty of care to other people as well as the animals and the environment around them. Similar to the biblical teachings, these values and responsibilities support the notion that God does exist. Moreover, these values and obligations are universal and thus, practiced by individuals of different faiths. As such, moral values and duties are supporting features proving the existence of a supreme being “God.”

Argument against Morality as a Proof of God’s existence

From an atheist point of view, morality in itself cannot be sufficient evidence to prove that God exists. Since individuals strive to live a fulfilling life, people have come up with rules to ensure that everyone can live a good life. In consideration of the perception that stealing is wrong, by not engaging in robbery, an individual is not approving that God is seeing him, he is avoiding the potential consequences. Also, there exist some values which appear to be moral in one society and immoral in others, yet they believe in the same God. For example, the issue of homosexuality raises ethical questions. Some religions embrace the culture, yet others refute. Since the belief is that there is one Supreme Being, then, the morality argument is insufficient evidence. Moreover, people are believed to have an intuition on right and wrong. It is expected that everyone knows that it is wrong to torture young children. Thus, it is not a matter of God’s commandments and expectations, but it is all about protecting children.

Justification of Morality as a Proof of God’s Existence

In most societies, individuals are taught the fundamental lifestyle values based on religious expectations. Whether atheists, Buddhists, Christians, or Muslims, all have the same views regarding morality, thus, supporting the ideology of the existence of God. However, there exist orthodox religions which tend to put up with secular deeds such as homosexuality which is rejected other faiths. However, their basis of accommodating such practices is the belief that God is all-Loving and does not judge his creatures. Therefore, the differences in doctrine is not a rejection of the existence of God, but it reflects the different ideologies about the supreme being. Similarly, since it is everyone’s objective to have a better life, it is only through God’s teaching that vices such as theft, corruption, adultery, and telling of lies can be avoided.

In conclusion, morality can be used as evidence to prove God’s existence. What drives most individual into acting morally is the recognition of a Supreme Being. The teachings of God imply that equality and happiness can only be achieved by practicing ethical values and duties. Thus, by practicing morality, we acknowledge the existence of God.

Ontological Proof of God’s Existence Essay

The existence of Almighty has often been a matter of debate. Many scholars and philosophers have been trying to prove that God exists. There are several theories, modern and traditional, that tend to explain that God exists. However, none of the theories have enough evidence that supports their claims. From an ontological perspective, the theory tends to argue that people believe in the Almighty, who cannot be compared with anything else. From this premise, the Almighty must indeed be omnipresent. If that extraordinary being is God, then God must be in existence (Klass & Weisgrau, 1999).

However, this argument is based on abstract ideas. The greatest being the theory is talking about is theoretical. To claim that something exists because of people’s beliefs is erroneous. The same argument can indeed be advanced for any other thing besides God (Klass & Weisgrau, 1999). It is because other marvelous things that cannot be conceived can either be an object or not specifically God, as the argument claims.

Further, to argue that this magnificent thing exists is a presupposition. Critically, something that exists must be seen or felt. It must be proven that it is there unquestionably. Therefore, to describe the extraordinary thing (God) as existing, yet it cannot be proved is a presupposition or an assumption. Because this argument lacks tangible proof on its claims, it cannot be used to assert that God exists. The arguments presented do not imply that the Almighty is nonexistent (Klass & Weisgrau, 1999). Rather, the arguments advanced by the ontological view do not provide clear proof that God exists.

What arguments would you use to convince someone that God really does exist?

Would you cite the appearance of things in nature having been designed as evidence, or the fulfillment of Biblical prophecies in our modern age?

As this thread does not seem to get any other answer I will reiterate that you can’t convince somebody with arguments when that person has reached their conclusions by means not based on arguments. I believe you can see that clearly when you examine the evident weakness of all the attempts to demonstrate the existence of god , for instance the unmoved mover argument, the first cause argument, the argument from beauty, the argument from design, the ontological argument, the cosmological argument and so on. All this “demonstrations” are tautological at best, bordering the ridiculous at worst and have never convinced anyone that was not already convinced that god exists. So this I can tell you for sure: whatever great argument you come up with at the end of this thread, however convincing, no, compelling you think it is, you will not convince me with it. Because I know deep in my heart that god does not exist and the argument is false. But if you believe in god I am sure that this will not convince you of the non-existence of god, nor would any other properly worked out argument. I see no way out of this impasse.

I’d use the arguments that have convinced me, although it’s not going to be Yahweh that I’m arguing in favor of. I’d argue in favor of a deistic clockwork god. My best guess is that in reality such a god (which would not be considered a god by a lot of people, but that’s a definitional problem) is probably something that a physicist would call a black hole in another universe and a white hole in ours.

I’ve thought about this for a long time and my conclusion is that nothing short of something supernatural or miraculous will do. Everything else can be chalked up as coincidence or randomness or natural cause and effect. And in an era of 15-second attention spans, nobody is going to want to listen to some hour-long apologetics lecture.

You can’t use the Bible as evidence to convince someone of God’s existence, because without belief in God, the Bible is just another ancient text. There are hundreds, many speaking of gods. Why take the Bible more seriously than the Enuma Elish or Rig Veda unless you believe in God?

For me, what it would take is actual evidence. Not some third party’s mystical revelation, but testable evidence. When somebody comes up with that, it will be front-page news worldwide. Until then, I think you’re just going to have to leave people to their disbelief.

What Pardel-Lux said. Since there is no scientific proof of the existence of God, those of us who trust the scientific method, as opposed to religious dogma, will never be convinced of something that can’t be proven scientifically.

You can talk about miracles, prophets, and divine inspiration, but inevitably they can’t be proven to exist, and can often be explained by what we already know about the human body and mind, and by the physical world.

As far as “Then how was the Universe created?” goes, just because science can’t explain everything doesn’t mean it’s not knowable. We learn new things about the Universe every day.

And how do you know it is something supernatural or miraculous, as opposed to very advanced technology? I would believe something was caused by aliens, or human super-villain scientists inside a volcano, before I would believe it was caused by deities.

You can’t reason yourself (or anyone else) into a position that reason itself rebels against.

Which god are you referring to?

At some point there are things that violate physics and couldn’t be explained as advanced technology, or would be too much to explain as something done by humans or aliens. Sure, it would be subjective but at some point it couldn’t be explained as that.

Right. Or at least that they violate the laws of physics as they apply to our universe as it currently is. Whether or not some thing, some place, or some when that operates under different laws of physics could be considered a god of some sort is, as I mentioned, a matter of how one chooses to define the term.

To start with a mass of super heated quarks and gravity, throw in evolution, and then end up with a universe of unimaginable complexity that actually works as a cohesive system is nothing less than a totally fabulous feat of engineering! That’s my argument.

Can’t be explained yet. Nobody knows what we will learn in the future that may explain whatever phenomenon appears to defy physics today. Maybe today’s physics is wrong. Science can change. Science isn’t dogma (a principle or set of principles laid down by an authority as incontrovertibly true.) Science can be wrong and adapts to new validated information.

Neil deGrasse Tyson said it best. “The good thing about Science is that it’s true, whether or not you believe in it.” He also said “The Universe is under no obligation to make sense to you.”

I agree with you, but I think you should be careful here, as questions like this are something of a “gotcha” intended to show that atheists are (equally) biased or whatever, whether the op intended this or not.

So I would say I never believe empirical claims on the basis of arguments alone. I always need to see some evidence. Arguing things into existence has a long and embarrassing history of error.

At this point we’ll probably derail this thread if we go on much further so I will try not to sidetrack too much. But, if, say, the events of Revelation happened as written (such as, say, two prophets who show up who nobody can kill and can strike the Earth with as many plagues as they want by their mere command and order (“tomorrow, 200,000 people in Chicago will die of smallpox despite there being zero smallpox today!”), and anyone who tries to harm them is consumed by flames right away,) that would be pretty hard to explain scientifically.

Or, if the Rapture happened and literally 1,000,000,000 people in the Earth (Christians) vanished from all 191 nations in the blink of an eye with absolutely no explanation - hard to explain that scientifically either.

At a certain point, a miracle would not be able to be hand-waved away as “Aw shucks, it’s just un-explained science.”

I don’t expect either the Revelation or Rapture events to happen, but if they did, there’d be no scientific “out” - it would have to be accepted as something in violation of science.

According to 1 Kings 18:21-39 , you can prove that your god beats your neighbors’ god by praying to bring down fire to a proper sacrifice.

And just because we don’t know something, that doesn’t prove that any particular god exists.

Sounds like a riff on what Niels Bohr supposedly said when asked why he carried a good-luck charm: “They say it works even if you don’t believe in it.”

He also said Pluto is not a planet and he’s totally wrong about that. You should find more credible sources to quote.

Why would you want to do so anyway?

This topic has been hashed out for many hundreds of years, and the conclusion is that you can’t “argue something into existence” by verbal tricks or ‘armchair philosophy’.

I think my favorite is, “Imagine the most perfect thing. Well, God is better than that, ergo God” or something to that effect.

Maybe if He stopped hating amputees? That might be some evidence. All of His medical cures seem to be of the hidden, hard-to-prove variety for some reason (probably something like, “can’t undermine free will” or some other silly thing).

My standard response when someone says they are an athiest or otherwise “don’t believe in God” is:

A person saying they don’t believe in God is like a fish saying it doesn’t believe in water.

IOW believe, don’t believe, argue, don’t argue, have “faith,” don’t have faith-- it’s all the same and your take on the matter is 100% irrelevant because it doesn’t change reality.
