Arguments for and against the existence of God have been proposed by philosophers, theologians, and others. In philosophical terminology, "existence-of-God" arguments concern schools of thought on the epistemology of the ontology of God.

The debate concerning the existence of God raises many philosophical issues. A basic problem is that there is no universally accepted definition of God. Some definitions of God's existence are so non-specific that it is certain that something exists that meets the definition; in stark contrast, there are suggestions that other definitions are self-contradictory.

A wide variety of arguments exist which can be categorized as metaphysical, logical, empirical, or subjective.

Although often regarded as a non-issue in much of western academia[1], the question of the existence of God is now subject to lively debate both in philosophy[2] and in popular culture.[3]

Philosophical issues

Definition of God's existence

Main articles: Definition, God, Deity, and Ontology

Today in the West, the term "God" typically refers to a monotheistic concept of a supreme being that is unlike any other being. Classical theism asserts that God possesses every possible perfection, including such qualities as omniscience, omnipotence, and perfect benevolence. Other philosophical approaches take a logically simple definition of God such as "the prime mover" or "the uncaused cause",[4] or "the ultimate creator"[5] or "a being than which nothing greater can be conceived"[6] from which the classical properties may be deduced.[7] By contrast Pantheists do not believe in a personal god. For example, Spinoza and his philosophical followers (such as Einstein) use the term 'God' in a particular philosophical sense, to mean (roughly) the essential substance/principles of nature.[8]

In monotheisms outside the Abrahamic traditions, the existence of God is discussed in similar terms. In the Advaita Vedanta school of Hinduism, reality is ultimately seen as a single, qualityless, changeless being called nirguna Brahman. Advaitin philosophy introduces the concept of saguna Brahman or Ishvara as a way of talking about Brahman to people. Ishvara, in turn, is ascribed such qualities as omniscience, omnipotence, and benevolence.[9]

Epistemology

Main articles: Epistemology and Sociology of knowledge

Epistemology is the branch of philosophy which studies the nature, origin, and scope of knowledge. One cannot be said to "know" something just because one believes it. Knowledge is, from an epistemological standpoint, distinguished from belief by justification.

Knowledge in the sense of "understanding of a fact or truth" can be divided in a posteriori knowledge, based on experience or deduction (see methodology), and a priori knowledge from introspection, axioms or self-evidence. Knowledge can also be described as a psychological state, since in a strict sense there can never be a posteriori knowledge proper (see relativism). Much of the disagreement about "proofs" of God's existence is due to different conceptions not only of the term "God" but also the terms "proof", "truth" and "knowledge". Religious belief from revelation or enlightenment (satori) falls in the second, a priori class of "knowledge".

Different conclusions as to the existence of God often rest on different criteria for deciding what methods are appropriate for deciding if something is true or not; some examples include

The problem of the supernatural

One problem posed by the question of the existence of a god is that traditional beliefs usually ascribe to God various supernatural powers. Supernatural beings may be able to conceal and reveal themselves for their own purposes, as for example in the tale of Baucis and Philemon. In addition, according to concepts of God, God is not part of the natural order, but the ultimate creator of nature and of the scientific laws.

Religious apologists offer the supernatural nature of God as one explanation of the inability of empirical methods to decide the question of God's existence. In Karl Popper's philosophy of science, the assertion of the existence of a supernatural God would be a non-falsifiable hypothesis, not in the domain of scientific investigation. The Non-overlapping Magisteria view proposed by Stephen Jay Gould also holds that the existence (or otherwise) of God is beyond the domain of science.

Proponents of intelligent design (I.D.) believe there is empirical evidence for Irreducible complexity pointing to the existence of an intelligent creator, though their claims are challenged by most of the scientific community. Some scientifically literate theists appear to have been impressed by the observation that certain natural laws and universal constants seem "fine-tuned" to favor the development of life (see Anthropic principle). However, reliance on phenomena which have not yet been resolved by natural explanations may be equated to the pejorative God of the gaps.

Logical positivists, such as Rudolf Carnap and A. J. Ayer viewed any talk of gods as literal nonsense. For the logical positivists and adherents of similar schools of thought, statements about religious or other transcendent experiences could not have a truth value, and were deemed to be without meaning.

Nature of relevant proofs/arguments

Since God (of the kind to which the proofs/arguments relate) is neither an entity in the universe nor a mathematical object it is not obvious what kinds of arguments/proofs are relevant to God's existence. Even if the concept of scientific proof were not problematic, the fact that there is no conclusive scientific proof of the existence, or non-existence, of God[10] mainly demonstrates that the existence of God is not a normal scientific question. John Polkinghorne suggests that the nearest analogy to the existence of God in physics are the ideas of quantum mechanics which are paradoxical but make sense of a great deal of disparate data.[11]

Alvin Plantinga compares the question of the existence of God to the question of the existence of other minds: both of which are notoriously impossible to "prove" against a determined skeptic.[12]

One approach, suggested by writers such as Stephen D. Unwin, is to treat (particular versions of) theism and naturalism as though they were two hypotheses in the Bayesian sense, to list certain data (or alleged data), about the world, and to suggest that the likelihoods of these data are significantly higher under one hypothesis than the other[13] Most of the arguments for, or against, the existence of God can be seen as pointing to particular aspects of the universe in this way. In almost all cases it is not seriously suggested by proponents of the arguments that they are irrefutable, merely that they make one worldview seem significantly more likely than the other. However, since an assessment of the weight of evidence depends on the prior probability that is assigned to each worldview, arguments that a theist finds convincing may seem thin to an atheist and vice-versa.[14]

Outside of western thought

Existence in absolute truth is central to Vedanta epistemology. Traditionally sense perception based approach was put into question as possibly misleading due to preconceived or superimposed ideas. But though all object-cognition can be doubted, the existence of the doubter remains a fact even in nastika traditions of mayavada schools following Adi Shankara.[15] The five eternal principles to be discussed under ontology, beginning with God or Isvara, the Ultimate Reality, cannot be established by the means of logic alone, and often require superior proof.[16] In Vaisnavism Vishnu, or his intimate ontological form of Krishna, is equated to personal absolute God of the Western traditions. Aspects of Krishna as svayam bhagavan in original Absolute Truth, sat chit ananda, are understood originating from three essential attributes of Krishna's form, i.e., "eternal existence" or sat, related to the brahman aspect; "knowledge" or chit, to the paramatman; and "bliss" or ananda in Sanskrit, to bhagavan.[17]

Arguments for the existence of God

Arguments from historical events or personages

Inductive arguments

Inductive arguments argue their conclusions through inductive reasoning.

Arguments from testimony

Arguments from testimony rely on the testimony or experience of certain witnesses, possibly embodying the propositions of a specific revealed religion. Swinburne argues that it is a principle of rationality that one should accept testimony unless there are strong reasons for not doing so.[22]

Arguments grounded in personal experience

Omega Point theory

Main article: Omega Point (Tipler)

According to physicist and mathematician Frank J. Tipler, the known laws of physics require that the universe end in the Omega Point[25], a cosmological singularity and state of infinite informational capacity, which Tipler claims is God.[26][27][28]

The eminent physicist, David Deutsch, has stated regarding Tipler's theory:[29]

I have mentioned several respects in which Tipler's 'God' differs from the God or gods that most religious people believe in. There are further differences, too. For instance, the people near the omega point could not, even if they wanted to, speak to us or communicate their wishes to us, or work miracles (today). They did not create the universe, and they did not invent the laws of physics – nor could they violate those laws if they wanted to. They may listen to prayers from the present day (perhaps by detecting very faint signals), but they cannot answer them. They are (and this we can infer from Popperian epistemology) opposed to religious faith, and have no wish to be worshipped. And so on. But Tipler ploughs on, and argues that most of the core features of the God of the Judaeo-Christian religions are also properties of the omega point. Most religious people will, I think, disagree with Tipler about what the core features of their religions are.

Arguments against belief in God

Each of the following arguments aims at showing either that a particular subset of gods do not exist (by showing them as inherently meaningless, contradictory, or at odds with known scientific or historical facts) or that there is insufficient reason to believe in them.

Empirical arguments

Empirical arguments depend on empirical data in order to prove their conclusions.

Deductive arguments

Deductive arguments attempt to prove their conclusions by deductive reasoning from true premises.

Inductive arguments

Inductive arguments argue their conclusions through inductive reasoning.

Subjective arguments

Similar to the subjective arguments for the existence of God, subjective arguments against the supernatural mainly rely on the testimony or experience of witnesses, or the propositions of a revealed religion in general.

Conclusions

Conclusions on the existence of God can be divided along numerous axes, producing a variety of orthogonal classifications. Theism and atheism relate to belief about the existence of gods, while gnosticism and agnosticism relates to belief about whether the existence of gods is (or can be) known. Ignosticism concerns belief regarding God's conceptual coherence.

Theism

The theistic conclusion is that the arguments indicate there is sufficient reason to believe that at least one god exists.

God exists and this can be demonstrated

The Catechism of the Catholic Church, following the Thomist tradition and the dogmatic definition of the First Vatican Council, affirms that it is a doctrine of the Catholic Church that God's existence has been rationally demonstrated. For the proofs of God's existence by Saint Thomas Aquinas see Quinquae viae. Many other Christian denominations share the view that God's existence can be demonstrated without recourse to claims of revelation.

On beliefs of Christian faith, theologians and philosophers make a distinction between:

  1. doctrines arising from special revelation that arise essentially from faith in divinely inspired revelations, including the life of Christ, but cannot be proved or even anticipated by reason alone, such as the doctrines of the Trinity or the Incarnation, and
  2. doctrines arising from general revelation, that is from reason alone drawing conclusions based on relatively obvious observations of the world and self.

The argument that the existence of God can be known to all, even prior to exposure to any divine revelation, predates Christianity. St. Paul made this argument when he insisted that pagans were without excuse because "since the creation of the world [God's] invisible nature, namely, his eternal power and deity, has been clearly perceived in the things that have been made".[33] In this Paul alludes to the proofs for a creator, later enunciated by St. Thomas[34] and others, but that had also been explored by the Greek philosophers.

Another apologetical school of thought, a sort of synthesis of various existing Dutch and American Reformed thinkers (such as, Abraham Kuyper, Benjamin Warfield, Herman Dooyeweerd), emerged in the late 1920s. This school was instituted by Cornelius Van Til, and came to be popularly called Presuppositional apologetics (though Van Til himself felt "transcendental" would be a more accurate title). The main distinction between this approach and the more classical evidentialist approach mentioned above is that the presuppositionalist denies any common ground between the believer and the non-believer, except that which the non-believer denies, namely, the assumption of the truth of the theistic worldview. In other words, presuppositionalists don't believe that the existence of God can be proven by appeal to raw, uninterpreted (or, "brute") facts, which have the same (theoretical) meaning to people with fundamentally different worldviews, because they deny that such a condition is even possible. They claim that the only possible proof for the existence of God is that the very same belief is the necessary condition to the intelligibility of all other human experience and action. In other words, they attempt to prove the existence of God by means of appeal to the alleged transcendental necessity of the belief -- indirectly (by appeal to the allegedly unavowed presuppositions of the non-believer's worldview) rather than directly (by appeal to some form of common factuality). In practice this school utilizes what have come to be known as transcendental arguments. In these arguments they claim to demonstrate that all human experience and action (even the condition of unbelief, itself) is a proof for the existence of God, because God's existence is the necessary condition of their intelligibility.

God exists, but this cannot be demonstrated or refuted

Others have suggested that the several logical and philosophical arguments for and against the existence of God miss the point. The word God has a meaning in human culture and history that does not correspond to the beings whose existence is supported by such arguments, assuming they are valid. The real question is not whether a "most perfect being" or an "uncaused first cause" exist; the real question is whether Yahweh or Vishnu or Zeus, or some other deity of attested human religion, exists, and if so, which deity. Most of these arguments do not resolve the issue of which of these figures is more likely to exist. Blaise Pascal suggested this objection in his Pensées when he wrote "The God of Abraham, God of Isaac, and God of Jacob — not the god of the philosophers!", see also Pascal's wager.

Some Christians note that the Christian faith teaches "salvation is by faith",[35] and that faith is reliance upon the faithfulness of God, which has little to do with the believer's ability to comprehend that in which he trusts.

The most extreme example of this position is called fideism, which holds that faith is simply the will to believe, and argues that if God's existence were rationally demonstrable, faith in its existence would become superfluous. Soren Kierkegaard argued that objective knowledge, such as 1+1=2, is unimportant to existence. If God could rationally be proven, his existence would be unimportant to humans. It is because God cannot rationally be proven that his existence is important to us. In The Justification of Knowledge, the Calvinist theologian Robert L. Reymond argues that believers should not attempt to prove the existence of God. Since he believes all such proofs are fundamentally unsound, believers should not place their confidence in them, much less resort to them in discussions with non-believers; rather, they should accept the content of revelation by faith. Reymond's position is similar to that of his mentor, Gordon Clark, which holds that all worldviews are based on certain unprovable first premises (or, axioms), and therefore are ultimately unprovable. The Christian theist therefore must simply choose to start with Christianity rather than anything else, by a "leap of faith." This position is also sometimes called presuppositional apologetics, but should not be confused with the Van Tillian variety discussed above.

An intermediate position is that of Alvin Plantinga who holds that a specific form of modal logic and an appeal to world-indexed properties render belief in the existence of God rational and justified, even though the existence of God cannot be proven in a mathematical sense. Plantinga equates knowledge of God's existence with kinds of knowledge that are rational but do not proceed through proof, such as sensory knowledge.[36]

Atheism

The atheistic conclusion is that the arguments indicate there is insufficient reason to believe that any gods exist.

Strong atheism

Strong atheism (or positive atheism) is the position that a god or gods do not exist. The strong atheist explicitly asserts the non-existence of gods.[37] Some strong atheists further assert that the existence of some or all gods is logically impossible, for example claiming that the combination of attributes which God may be asserted to have (for example: omnipotence, omniscience, omnipresence, transcendence, omnibenevolence) is logically contradictory, incomprehensible, or absurd, and therefore that the non-existence of such a god is a priori true.

Metaphysical naturalism is a common worldview associated with strong atheism.

Weak atheism

The term weak atheism (or negative atheism) is used in two main senses: (a) of those who do not assert strong atheism ("Gods do not exist") but rather the more minimal statement that for a variety of reasons (principally the lack of credible scientific evidence) there are no good reasons and no credible grounds for believing that gods exist ("I do not believe that gods exist" as opposed to "I believe that gods do not exist"); or (b) those who neither believe that a god or gods exists, nor believe that no gods exist. This is orthogonal to agnosticism which states that whether gods exist is either unknown or unknowable. It should be noted that there is some controversy about this use of the term.

Agnosticism

The term Agnostic is generally meant to describe a person who doesn't believe that the existence of God is an answerable question.

Psychological Issues

See also: Evolutionary psychology of religion

Several authors have offered psychological or sociological explanations for belief in the existence of God. We ask why we are here and whether life has purpose; we are anxious about being alone. Religious beliefs may recruit the cognitive mechanisms. William James emphasized the inner religious struggle between melancholy and happiness, and pointed to trance as a cognitive mechanism. Sigmund Freud stressed fear and pain, the need for a powerful parent to care for us, the obsessional nature of ritual, and the hypnotic state a community can induce.

Pascal Boyer's "Religion Explained," (2002) based in part on his anthropological field work, treats belief in God as the result of the brain's tendency towards agency detection, the idea that because of evolutionary pressures, we err on the side of attributing agency where there isn't any. In Boyer's view, belief in 'minimally counterintuitive' supernatural entities spread and became culturally fixed because of their memorability -- beings that differ from the ordinary in a small number of ways, such as being invisible, able to fly, or having access to strategic and otherwise secret information.

Scott Atran's "In Gods We Trust: The Evolutionary Landscape of Religion" (2002) makes a similar argument, and adds examination of the socially coordinating aspects of shared belief. In "Minds and Gods: The Cognitive Foundations of Religion," Todd Tremlin follows Boyer in arguing that universal human cognitive process naturally produce Gods. In particular, an agency detection device (ADD) and a theory of mind module (ToMM) lead us to expect an agent behind every event.
