Existence of God

The existence of God is a subject of debate in the philosophy of religion and popular culture.[1]

A wide variety of arguments for and against the existence of God can be categorized as metaphysical, logical, empirical, or subjective. In philosophical terms, the question of the existence of God involves the disciplines of epistemology (the nature and scope of knowledge) and ontology (study of the nature of being, existence, or reality) and the theory of value (since some definitions of God include "perfection").

The Western tradition of philosophical discussion of the existence of God began with Plato and Aristotle, who made arguments that would now be categorized as cosmological. Other arguments for the existence of God have been proposed by St. Anselm, who formulated the first ontological argument; Ibn Rushd (Averroes) and Thomas Aquinas, who presented their own versions of the cosmological argument (the kalam argument and the first way, respectively); René Descartes, who said that the existence of a benevolent God is logically necessary for the evidence of the senses to be meaningful. John Calvin argued for a sensus divinitatis, which gives each human a knowledge of God's existence.

Philosophers who have provided arguments against the existence of God include Immanuel Kant, David Hume, Friedrich Nietzsche and Bertrand Russell. In modern culture, the question of God's existence has been discussed by scientists such as Stephen Hawking, Francis Collins, Lawrence M. Krauss, Richard Dawkins, Carl Sagan,[2] Neil deGrasse Tyson, John Lennox and Sam Harris, as well as philosophers including Richard Swinburne, Alvin Plantinga, William Lane Craig, Rebecca Goldstein, A. C. Grayling, Daniel Dennett, Edward Feser and David Bentley Hart.

Scientists follow the scientific method, within which theories must be verifiable by physical experiment. The majority of prominent conceptions of God explicitly or effectively posit a being which is not testable either by proof or disproof. On these bases, the question regarding the existence of God, one for which evidence cannot be tested, may lie outside the purview of modern science by definition. The Catholic Church maintains that knowledge of the existence of God is the "natural light of human reason".[3] Fideists maintain that belief in the existence of God may not be amenable to demonstration or refutation, but rests on faith alone.

Atheists view arguments for the existence of God as insufficient, mistaken or weighing less in comparison to arguments against whereas some religions, such as Buddhism, are not concerned with the existence of gods at all and yet other religions, such as Jainism, reject the possibility of a creator deity.

Positions

Positions on the existence of God can be divided along numerous axes, producing a variety of orthogonal classifications. Theism and atheism are positions of belief (or lack of it), while gnosticism and agnosticism are positions of knowledge (or the lack of it). Ignosticism concerns belief regarding God's conceptual coherence. Apatheism concerns belief regarding the practical importance of whether God exists.

For the purposes of discussion, Richard Dawkins described seven "milestones" on his spectrum of theistic probability:[4]

  1. Strong theist. 100% probability of God. In the words of C.G. Jung: "I do not believe, I know."
  2. De facto theist. Very high probability but short of 100%. "I don't know for certain, but I strongly believe in God and live my life on the assumption that he is there."
  3. Leaning towards theism. Higher than 50% but not very high. "I am very uncertain, but I am inclined to believe in God."
  4. Completely impartial. Exactly 50%. "God's existence and non-existence are exactly equiprobable."
  5. Leaning towards atheism. Lower than 50% but not very low. "I do not know whether God exists but I'm inclined to be skeptical."
  6. De facto atheist. Very low probability, but short of zero. "I don't know for certain but I think God is very improbable, and I live my life on the assumption that he is not there."
  7. Strong atheist. "I know there is no God, with the same conviction as Jung knows there is one."

Theism

The Catholic Church, following the teachings of Paul the Apostle, Thomas Aquinas, and the First Vatican Council, affirms that God's existence "can be known with certainty from the created world by the natural light of human reason".[5]

Traditional religious definition of God: personal, omnipotent, benevolent, transcendent

In classical theism, God is characterized as the metaphysically ultimate being (the first, timeless, absolutely simple and sovereign being, who is devoid of any anthropomorphic qualities), in distinction to other conceptions such as theistic personalism, open theism, and process theism. Classical theists do not believe that God can be completely defined. They believe it would contradict the transcendent nature of God for mere humans to define him. Robert Barron explains by analogy that it seems impossible for a two-dimensional object to conceive of three-dimensional humans.[6]

In modern Western societies, the concepts of God typically entail a monotheistic, supreme, ultimate, and personal being, as found in the Christian, Islamic and Jewish traditions. In monotheistic religions outside the Abrahamic traditions, the existence of God is discussed in similar terms. In these traditions, God is also identified as the author (either directly or by inspiration) of certain texts, or that certain texts describe specific historical events caused by the God in question or communications from God (whether in direct speech or via dreams or omens). Some traditions also believe that God is the entity which is currently answering prayers for intervention or information or opinions.

Ibn rushd
Ibn Rushd a 12th-century Islamic scholar

Many Islamic scholars have used philosophical and rational arguments to prove the existence of God. For example, Ibn Rushd, a 12th-century Islamic scholar, philosopher, and physician, states there are only two arguments worthy of adherence, both of which are found in what he calls the "Precious Book" (The Qur'an). Rushd cites “providence” and “invention” in using the Qur'an's parables to claim the existence of God. Rushd argues that the Earth's weather patterns are conditioned to support human life; thus, if the planet is so finely-tuned to maintain life, then it suggests a fine tuner - God. The Sun and the Moon are not just random objects floating in the Milky Way, rather they serve us day and night, and the way nature works and how life is formed, humankind benefits from it. Rushd essentially comes to a conclusion that there has to be a higher being who has made everything perfectly to serve the needs of human beings.[7][8][9][10]

Moses ben Maimon, widely known as Maimonides, was a Jewish scholar who tried to logically prove the existence of God. Maimonides offered proofs for the existence of God, but he did not begin with defining God first, like many others do. Rather, he used the description of the earth and the universe to prove the existence of God. He talked about the Heavenly bodies and how they are committed to eternal motion. Maimonides argued that because every physical object is finite, it can only contain a finite amount of power. If everything in the universe, which includes all the planets and the stars, is finite, then there has to be an infinite power to push forth the motion of everything in the universe. Narrowing down to an infinite being, the only thing that can explain the motion is an infinite being (meaning God) which is neither a body nor a force in the body. Maimonides believed that this argument gives us a ground to believe that God is, not an idea of what God is. He believed that God cannot be understood or be compared.[11]

Non-personal definitions of God

In pantheism, God and the universe are considered to be the same thing. In this view, the natural sciences are essentially studying the nature of God. This definition of God creates the philosophical problem that a universe with God and one without God are the same, other than the words used to describe it.

Deism and panentheism assert that there is a God distinct from, or which extends beyond (either in time or in space or in some other way) the universe. These positions deny that God intervenes in the operation of the universe, including communicating with humans personally. The notion that God never intervenes or communicates with the universe, or may have evolved into the universe, makes it difficult, if not by definition impossible, to distinguish between a universe with God and one without.

Debate about how theism should be argued

In Christian faith, theologians and philosophers make a distinction between: (a) preambles of faith and (b) articles of faith. The preambles include alleged truths contained in revelation which are nevertheless demonstrable by reason, e.g., the immortality of the soul, the existence of God. The articles of faith, on the other hand, contain truths that cannot be proven or reached by reason alone and presuppose the truths of the preambles, e.g., the Holy Trinity, is not demonstrable and presupposes the existence of God.

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 said 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".[12] In this Paul alludes to the proofs for a creator, later enunciated by St. Thomas[13] and others, but that had also been explored by the Greek philosophers.

Another apologetical school of thought, including 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 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 do not 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. They attempt to prove the existence of God by means of appeal to the transcendental necessity of the belief—indirectly (by appeal to the 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.

Alvin Plantinga presents an argument for the existence of God using modal logic.[14] Others have said that the 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 Jehovah, Zeus, Ra, Krishna, or any gods of any religion exist, and if so, which gods? On the other hand, many theists equate all monotheistic or henotheistic "most perfect Beings", no matter what name is assigned to them/him, as the one monotheistic God (one example would be understanding the Muslim Allah, Christian Yhwh, and Chinese Shangdi as different names for the same Being). Most of these arguments do not resolve the issue of which of these figures is more likely to exist. These arguments fail to make the distinction between immanent gods and a Transcendent God.

Some Christians note that the Christian faith teaches "salvation is by faith",[15] and that faith is reliance upon the faithfulness of God. 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. Søren 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.

Atheism

The atheistic conclusion is that the arguments and evidence both indicate there is insufficient reason to believe that any gods exist, and that personal subjective religious experiences say something about the human experience rather than the nature of reality itself; therefore, one has no reason to believe that a god exists.

Positive atheism

Positive atheism (also called "strong atheism" and "hard atheism") is a form of atheism that asserts that no deities exist.[16][17][18] The strong atheist explicitly asserts the non-existence of gods. Strong atheists further assert that the existence of gods is logically impossible, stating that the combination of attributes which God may be asserted to have (omnipotence, omniscience, omnipresence, transcendence, omnibenevolence) are logically contradictory, incomprehensible, or absurd, and therefore the existence of such a god is a priori false. Metaphysical naturalism is a common worldview associated with strong atheism.

Negative atheism

Negative atheism (also called "weak atheism" and "soft atheism") is any type of atheism other than positive, wherein a person does not believe in the existence of any deities, but does not explicitly assert there to be none.[16][17][18]

Agnosticism

Agnosticism is the view that the truth value of certain claims—especially claims about the existence of any deity, but also other religious and metaphysical claims—is unknown or unknowable.[19] Agnosticism does not define one's belief or disbelief in gods; agnostics may still identify themselves as theists or atheists.[20]

Strong agnosticism

Strong agnosticism is the belief that it is impossible for humans to know whether or not any deities exist.

Weak agnosticism

Weak agnosticism is the belief that the existence or nonexistence of deities is unknown but not necessarily unknowable.

Agnostic theism

Agnostic theism is the philosophical view that encompasses both theism and agnosticism. An agnostic theist believes in the existence of a god or God, but regards the basis of this proposition as unknown or inherently unknowable. Agnostic theists may also insist on ignorance regarding the properties of the gods they believe in.[21]

Agnostic atheism

Agnostic atheism is a philosophical position that encompasses both atheism and agnosticism. Agnostic atheists are atheistic because they do not hold a belief in the existence of any deity and agnostic because they claim that the existence of a deity is either unknowable in principle or currently unknown in fact.

The theologian Robert Flint explains:

If a man have failed to find any good reason for believing that there is a God, it is perfectly natural and rational that he should not believe that there is a God; and if so, he is an atheist, although he assume no superhuman knowledge, but merely the ordinary human power of judging of evidence. If he go farther, and, after an investigation into the nature and reach of human knowledge, ending in the conclusion that the existence of God is incapable of proof, cease to believe in it on the ground that he cannot know it to be true, he is an agnostic and also an atheist, an agnostic-atheist—an atheist because an agnostic."[22]

Apatheism

An apatheist is someone who is not interested in accepting or denying any claims that gods exist or do not exist. An apatheist lives as if there are no gods and explains natural phenomena without reference to any deities. The existence of gods is not rejected, but may be designated unnecessary or useless; gods neither provide purpose to life, nor influence everyday life, according to this view.[23]

Ignosticism

The ignostic (or igtheist) usually concludes that the question of God's existence or nonexistence is usually not worth discussing because concepts like "God" are usually not sufficiently clearly defined. Ignosticism or igtheism is the theological position that every other theological position (including agnosticism and atheism) assumes too much about the concept of God and many other theological concepts. It can be defined as encompassing two related views about the existence of God. The view that a coherent definition of God must be presented before the question of the existence of God can be meaningfully discussed. Furthermore, if that definition is unfalsifiable, the ignostic takes the theological noncognitivist position that the question of the existence of God (per that definition) is meaningless. In this case, the concept of God is not considered meaningless; the term "God" is considered meaningless. The second view is synonymous with theological noncognitivism, and skips the step of first asking "What is meant by 'God'?" before proclaiming the original question "Does God exist?" as meaningless.

Some philosophers have seen ignosticism as a variation of agnosticism or atheism,[24] while others have considered it to be distinct. An ignostic maintains that he cannot even say whether he is a theist or an atheist until a sufficient definition of theism is put forth.

The term "ignosticism" was coined in the 1960s by Sherwin Wine, a rabbi and a founding figure of Humanistic Judaism. The term "igtheism" was coined by the secular humanist Paul Kurtz in his 1992 book The New Skepticism.[25]

Philosophical issues

The problem of the supernatural

One problem posed by the question of the existence of 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. Thus in Aristotelian philosophy, God is viewed as part of the explanatory structure needed to support scientific conclusions and any powers God possesses are—strictly speaking—of the natural order that is derived from God's place as originator of nature (see also Monadology).

In Karl Popper's philosophy of science, belief in a supernatural God is outside the natural domain of scientific investigation because all scientific hypotheses must be falsifiable in the natural world. The non-overlapping magisteria view proposed by Stephen Jay Gould also holds that the existence (or otherwise) of God is irrelevant to and beyond the domain of science.

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 can not have a truth value, and are deemed to be without meaning, because such statements do not have any clear verification criteria. As the Christian biologist Scott C. Todd put it "Even if all the data pointed to an intelligent designer, such a hypothesis is excluded from science because it is not naturalistic."[26] This argument limits the domain of science to the empirically observable and limits the domain of God to the unprovable.

Nature of relevant proofs and arguments

John Polkinghorne suggests that the nearest analogy to the existence of God in physics is the ideas of quantum mechanics which are seemingly paradoxical but make sense of a great deal of disparate data.[27]

Alvin Plantinga compares the question of the existence of God to the question of the existence of other minds, claiming both are notoriously impossible to "prove" against a determined skeptic.[28]

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.[29] 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.[30]

Philosophers, such as Wittgenstein, take a view that is considered anti-realist and oppose philosophical arguments related to God's existence. For instance, Charles Taylor contends that the real is whatever will not go away. If we cannot reduce talk about God to anything else, or replace it, or prove it false, then perhaps God is as real as anything else.[31]

In George Berkeley's A Treatise Concerning the Principles of Human Knowledge of 1710, he argued that a "naked thought" cannot exist, and that a perception is a thought; therefore only minds can be proven to exist, since all else is merely an idea conveyed by a perception. From this Berkeley argued that the universe is based upon observation and is non-objective. However, he noted that the universe includes "ideas" not perceptible to humankind, and that there must, therefore, exist an omniscient superobserver, which perceives such things. Berkeley considered this proof of the existence of the Christian god.

C.S. Lewis, in Mere Christianity and elsewhere, raised the argument from desire. He posed that all natural desires have a natural object. One thirsts, and there exists water to quench this thirst; One hungers, and there exists food to satisfy this hunger. He then argued that the human desire for perfect justice, perfect peace, perfect happiness, and other intangibles strongly implies the existence of such things, though they seem unobtainable on earth. He further posed that the unquenchable desires of this life strongly imply that we are intended for a different life, necessarily governed by a God who can provide the desired intangibles.[32]

Outside of Western thought

Existence in absolute truth is central to Vedanta epistemology. Traditional sense perception based approaches were 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.[33] 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.[34] 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.[35]

Arguments for the existence of God

Empirical arguments

Argument from beauty

One form of the argument from beauty is that the elegance of the laws of physics, which have been empirically discovered, or the elegant laws of mathematics, which are abstract but which have empirically proven to be useful, is evidence of a creator deity who has arranged these things to be beautiful and not ugly.

Argument from consciousness

The argument from consciousness claims that human consciousness cannot be explained by the physical mechanisms of the human body and brain, therefore, asserting that there must be non-physical aspects to human consciousness. This is held as indirect evidence of God, given that notions about souls and the afterlife in Christianity and Islam would be consistent with such a claim. Critics point out that non-physical aspects of consciousness could exist in a universe without any gods; for example, some religions that believe in reincarnation are compatible with atheism, monotheism, and polytheism.

The notion of the soul was created before modern understanding of neural networks and the physiology of the brain. Decades of experimentation lead cognitive science to consider thought and emotion as physical processes although the experience of consciousness still remains poorly understood. The hard problem of consciousness remains as to whether different people subjectively experience the world in the same way — for example, that the color blue looks the same inside the minds of different people, though this is a philosophical problem with both physical and non-physical explanations.

Aquinas' Five Ways

In article 3, question 2, first part of his Summa Theologica, Thomas Aquinas developed his five arguments for God's existence. These arguments are grounded in an Aristotelian ontology and make use of the infinite regression argument.[36][37] Aquinas did not intend to fully prove the existence of God as he is orthodoxly conceived (with all of his traditional attributes), but proposed his Five Ways as a first stage, which he built upon later in his work.[38] Aquinas' Five Ways argued from the unmoved mover, first cause, necessary being, argument from degree, and the teleological argument.

  • The unmoved mover argument asserts that, from our experience of motion in the universe (motion being the transition from potentiality to actuality) we can see that there must have been an initial mover. Aquinas argued that whatever is in motion must be put in motion by another thing, so there must be an unmoved mover.[36]
  • Aquinas' argument from first cause started with the premise that it is impossible for a being to cause itself (because it would have to exist before it caused itself) and that it is impossible for there to be an infinite chain of causes, which would result in infinite regress. Therefore, there must be a first cause, itself uncaused.[36]
  • The argument from necessary being asserts that all beings are contingent, meaning that it is possible for them not to exist. Aquinas argued that if everything can possibly not exist, there must have been a time when nothing existed; as things exist now, there must exist a being with necessary existence, regarded as God.[36]
  • Aquinas argued from degree, considering the occurrence of degrees of goodness. He believed that things which are called good, must be called good in relation to a standard of good—a maximum. There must be a maximum goodness that which causes all goodness.[36]
  • The teleological argument asserts the view that things without intelligence are ordered towards a purpose. Aquinas argued that unintelligent objects cannot be ordered unless they are done so by an intelligent being, which means that there must be an intelligent being to move objects to their ends: God.[36]

Dialectical argument

Philosopher Georg Hegel signed a publishing contract in 1831 for his final book, Lectures on the Proofs of the Existence of God (1831). Sadly, Hegel died that year, before completing his first draft of that work. What we know about this planned work we find in the pages of his Lectures on the Philosophy of Religion (1818-1831). There we find that Hegel proposed a dialectical reworking of the three classical proofs of the existence of God, namely: (1) the cosmological argument; (2) the teleological argument; and (3) the ontological argument. Hegel recognized that Immanuel Kant's Critique of Pure Reason had sharply criticized the three classical proofs, and as a veteran critic of Kantian epistemology, Hegel chose to show where Kant, Schleiermacher and Jacobi had been mistaken in their negative positions over the three classical proofs. Thus, Hegel went about reworking these classical arguments by using his own dialectical logic.

Rational warrant

Philosopher Stephen Toulmin is notable for his work in the history of ideas[39] that features the (rational) warrant: a statement that connects the premises to a conclusion.

Joseph Hinman applied Toulmin's approach in his argument for the existence of God, particularly in his book The Trace of God: A Rational Warrant for Belief.[40] Instead of attempting to prove the existence of God, Hinman argues you can "demonstrate the rationally-warranted nature of belief".[41]

Hinman uses a wide range of studies, including ones by Robert Wuthnow, Andrew Greeley, Mathes and Kathleen Nobel to establish that mystical experiences are life-transformative in a way that is significant, positive and lasting.[42] He draws on additional work to add several additional major points to his argument. First, the people who have these experiences not only do not exhibit traditional signs of mental illness but, often, are in better mental and physical health than the general population due to the experience.[43] Second, the experiences work. In other words, they provide a framework for navigating life that is useful and effective.[44] All of the evidence of the positive effects of the experience upon people's lives he, adapting a term from Derrida, terms "the trace of God": the footprints left behind that point to the impact.

Finally, he discusses how both religious experience and belief in God is, and has always been, normative among humans:[45] people do not need to prove the existence of God. If there is no need to prove, Hinman argues, and the Trace of God (for instance, the impact of mystical experiences on them), belief in God is rationally warranted.

Deductive arguments

Ontological argument

The ontological argument has been formulated by philosophers including St. Anselm and René Descartes. The argument proposes that God's existence is self-evident. The logic, depending on the formulation, reads roughly as follows:[46]

Whatever is contained in a clear and distinct idea of a thing must be predicated of that thing; but a clear and distinct idea of an absolutely perfect Being contains the idea of actual existence; therefore since we have the idea of an absolutely perfect Being such a Being must really exist.[46]

Thomas Aquinas criticized the argument for proposing a definition of God which, if God is transcendent, should be impossible for humans.[47] Immanuel Kant criticized the proof from a logical standpoint: he stated that the term "God" really signifies two different terms: both idea of God, and God. Kant concluded that the proof is equivocation, based on the ambiguity of the word God.[48] Kant also challenged the argument's assumption that existence is a predicate (of perfection) because it does not add anything to the essence of a being. If existence is not a predicate, then it is not necessarily true that the greatest possible being exists.[49] A common rebuttal to Kant's critique is that, although "existence" does add something to both the concept and the reality of God, the concept would be vastly different if its referent is an unreal Being. Another response to Kant is attributed to Alvin Plantinga who explains that even if one were to grant Kant that "existence" is not a real predicate, "Necessary Existence", which is the correct formulation of an understanding of God, is a real predicate, thus according to Plantinga Kant's argument is refuted.[50]

Inductive arguments

Inductive arguments argue their conclusions through inductive reasoning.

  • Another class of philosophers asserts that the proofs for the existence of God present a fairly large probability though not absolute certainty. A number of obscure points, they say, always remain; an act of faith is required to dismiss these difficulties. This view is maintained, among others, by the Scottish statesman Arthur Balfour in his book The Foundations of Belief (1895). The opinions set forth in this work were adopted in France by Ferdinand Brunetière, the editor of the Revue des deux Mondes. Many orthodox Protestants express themselves in the same manner, as, for instance, Dr. E. Dennert, President of the Kepler Society, in his work Ist Gott tot?[51]

Other arguments

  • The hypothesis of well design proposes that certain features of the universe and of living things are the product of an intelligent cause.[52] Its proponents are mainly Christians.[53]
  • Argument from belief in God being properly basic as presented by Alvin Plantinga.[54]
  • Argument from the confluence of proper function and reliability and the evolutionary argument against naturalism, concluding that naturalism is incapable of providing humans with the cognitive apparatus necessary for their knowledge to have positive epistemic status.[55]
  • Argument from Personal Identity.[56]
  • Argument from the "divine attributes of scientific law".[57]

Subjective arguments

Arguments from historical events or personages

Arguments from testimony

Arguments from testimony rely on the testimony or experience of 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.[63]

  • The witness argument gives credibility to personal witnesses, contemporary and throughout the ages. A variation of this is the argument from miracles (also referred to as "the priest stories") which relies on testimony of supernatural events to establish the existence of God.
  • The majority argument argues that the theism of people throughout most of recorded history and in many different places provides prima facie demonstration of God's existence.
  • The sincere seeker's argument, espoused by Muslim Sufis of the Tasawwuf tradition, posits that every individual who follows a formulaic path towards guidance, arrives at the same destination of conviction in the existence of God and specifically in the monotheistic tenets and laws of Islam. This apparent natural law for guidance and belief could only be consistent if the formula and supplication were being answered by the same Divine entity being addressed, as claimed in Islamic revelations. This was formally organized by Imam Abu Hamid Al-Ghazali in such notable works as "Deliverance from Error" and "The Alchemy of Happiness," in Arabic "Kimiya-yi sa'ādat". The path includes following the golden rule of no harm to others and treating others with compassion, silence or minimal speech, seclusion, daily fasting or minimalist diet of water and basic nourishment, honest wages, and daily supplication towards "the Creator of the Universe" for guidance.[58][59]
  • The Argument from a proper basis argues that belief in God is "properly basic"; that it is similar to statements like "I see a chair" or "I feel pain". Such beliefs are non-falsifiable and, thus, neither provable nor disprovable; they concern perceptual beliefs or indisputable mental states.
  • In Germany, the School of Friedrich Heinrich Jacobi taught that human reason is able to perceive the suprasensible. Jacobi distinguished three faculties: sense, reason, and understanding. Just as sense has immediate perception of the material so has reason immediate perception of the immaterial, while the understanding brings these perceptions to a person's consciousness and unites them to one another.[64] God's existence, then, cannot be proven (Jacobi, like Immanuel Kant, rejected the absolute value of the principle of causality), it must be felt by the mind.
  • The same theory was advocated in Germany by Friedrich Schleiermacher, who assumed an inner religious sense by means of which people feel religious truths. According to Schleiermacher, religion consists solely in this inner perception, and dogmatic doctrines are inessential.[65]
  • Brahma Kumaris religion was established in 1936, when God was said to enter the body of diamond merchant Lekhraj Kripalani (1876–1969) in Hyderabad, Sindh and started to speak through him.[66][67]

Hindu arguments

The school of Vedanta argues that one of the proofs of the existence of God is the law of karma. In a commentary to Brahma Sutras (III, 2, 38, and 41), Adi Sankara argues that the original karmic actions themselves cannot bring about the proper results at some future time; neither can super sensuous, non-intelligent qualities like adrsta by themselves mediate the appropriate, justly deserved pleasure and pain. The fruits, according to him must be administered through the action of a conscious agent, namely, a supreme being (Ishvara).[68] The Nyaya school make similar arguments.

Arguments against the existence of God

Each of the arguments below aims to show that a particular set of gods does not exist—by demonstrating them to be inherently meaningless, contradictory, or at odds with known scientific or historical facts—or that there is insufficient proof to say that they do exist.

Empirical arguments

The following empirical arguments rely on observations or experimentation to yield their conclusions.

  • The argument from inconsistent revelations contests the existence of the deity called God as described in scriptures—such as the Hindu Vedas, the Jewish Tanakh, the Christian Bible, the Muslim Qur'an, the Book of Mormon or the Baha'i Aqdas—by identifying apparent contradictions between different scriptures, within a single scripture, or between scripture and known facts.
  • The problem of evil contests the existence of a god who is both omnipotent and omnibenevolent by arguing that such a god should not permit the existence of evil or suffering. The theist responses are called theodicies.
  • The destiny of the unevangelized, by which persons who have never even heard of a particular revelation might be harshly punished for not following its dictates.
  • The argument from poor design contests the idea that God created life on the basis that lifeforms, including humans, seem to exhibit poor design.
  • The argument from nonbelief contests the existence of an omnipotent God who wants humans to believe in him by arguing that such a god would do a better job of gathering believers.
  • The argument from parsimony (using Occam's razor) contends that since natural (non-supernatural) theories adequately explain the development of religion and belief in gods,[69] the actual existence of such supernatural agents is superfluous and may be dismissed unless otherwise proven to be required to explain the phenomenon.
  • The analogy of Russell's teapot argues that the burden of proof for the existence of God lies with the theist rather than the atheist; it can be considered an extension of Occam's Razor.

Deductive arguments

The following arguments deduce, mostly through self-contradiction, the existence of a God as "the Creator".

  • Stephen Hawking and co-author Leonard Mlodinow state in their book The Grand Design that it is reasonable to ask who or what created the universe, but if the answer is God, then the question has merely been deflected to that of who created God. Both authors claim that it is possible to answer these questions purely within the realm of science, and without invoking any divine beings.[70] Christian mathematicians and scientists, most notably Leonhard Euler, Bernard d'Espagnat[71] and John Lennox,[72] disagree with that kind of skeptical argument.
  • A counter-argument against God as the Creator takes the assumption of the Cosmological argument ("the chicken or the egg"), that things cannot exist without creators, and applies it to God, setting up an infinite regress.
  • Dawkins' Ultimate Boeing 747 gambit analogizes the above. Some theists argue that evolution is akin to a hurricane assembling a Boeing 747 — that the universe (or life) is too complex not to have been designed by someone, who theists call God. Dawkin's counter-argument is that such a God would himself be complex — the "Ultimate" Boeing 747 — and therefore require a designer.
  • Theological noncognitivism is the argument that religious language – specifically, words such as "God" – are not cognitively meaningful and that irreducible definitions of God are circular.

Some arguments focus on the existence of specific conceptions of God as being omniscient, omnipotent, and morally perfect.

  • The omnipotence paradox suggests that the concept of an omnipotent entity is logically contradictory by considering questions such as "Can God create a rock so big that He cannot move it?" or "If God is all powerful, could God create a being more powerful than Himself?"
  • Similarly, the omniscience paradox argues that God cannot be omniscient because he would not know how to create something unknown to himself.
  • Another argument points to the contradiction of omniscience and omnipotence arguing that God is bound to follow whatever God foreknows himself doing.
  • Argument from free will contends that omniscience and the free will of humanity are incompatible and that any conception of God that incorporates both properties is therefore inherently contradictory: if God is omniscient, then God already knows humanity's future, contradicting the claim of free will.
  • The anthropic argument states that if God is omniscient, omnipotent, and morally perfect, he would have created other morally perfect beings instead of imperfect ones, such as humans.
  • The problem of hell is the idea that eternal damnation contradicts God's omnibenevolence and omnipresence.

Inductive arguments

Inductive arguments argue their conclusions through inductive reasoning.

  • The atheist-existential argument for the non-existence of a perfect sentient being states that if existence precedes essence, it follows from the meaning of the term sentient that a sentient being cannot be complete or perfect. It is touched upon by Jean-Paul Sartre in Being and Nothingness. Sartre's phrasing is that God would be a pour-soi [a being-for-itself; a consciousness] who is also an en-soi [a being-in-itself; a thing]: which is a contradiction in terms. The argument is echoed thus in Salman Rushdie's novel Grimus: "That which is complete is also dead."
  • The "no reason" argument tries to show that an omnipotent and omniscient being would not have any reason to act in any way, specifically by creating the universe, because it would have no needs, wants, or desires since these very concepts are subjectively human. Since the universe exists, there is a contradiction, and therefore, an omnipotent god cannot exist. This argument is expounded upon by Scott Adams in the book God's Debris, which puts forward a form of Pandeism as its fundamental theological model. A similar argument is put forward in Ludwig von Mises's "Human Action". He referred to it as the "praxeological argument" and claimed that a perfect being would have long ago satisfied all its wants and desires and would no longer be able to take action in the present without proving that it had been unable to achieve its wants faster—showing it imperfect.
  • The "historical induction" argument concludes that since most theistic religions throughout history (e.g. ancient Egyptian religion, ancient Greek religion) and their gods ultimately come to be regarded as untrue or incorrect, all theistic religions, including contemporary ones, are therefore most likely untrue/incorrect by induction. H. L. Mencken wrote a short piece about the topic entitled "Memorial Service" in 1922.[73] It is implied as part of Stephen F. Roberts' popular quotation:

    I contend that we are both atheists. I just believe in one fewer god than you do. When you understand why you dismiss all the other possible gods, you will understand why I dismiss yours.

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.

  • The witness argument gives credibility to personal witnesses, contemporary and from the past, who disbelieve or strongly doubt the existence of God.
  • The conflicted religions argument notes that many religions give differing accounts as to what God is and what God wants; since all the contradictory accounts cannot be correct, many if not all religions must be incorrect.
  • The disappointment argument claims that if, when asked for, there is no visible help from God, there is no reason to believe that there is a God.

Hindu arguments

Atheistic Hindu doctrines cite various arguments for rejecting a creator God or Ishvara. The Sāṁkhyapravacana Sūtra of the Samkhya school states that there is no philosophical place for a creator God in this system. It is also argued in this text that the existence of Ishvara (God) cannot be proved and hence cannot be admitted to exist.[74] Classical Samkhya argues against the existence of God on metaphysical grounds. For instance, it argues that an unchanging God cannot be the source of an ever-changing world. It says God is a necessary metaphysical assumption demanded by circumstances.[75] The Sutras of Samkhya endeavor to prove that the idea of God is inconceivable and self-contradictory, and some commentaries speak plainly on this subject. The Sankhya- tattva-kaumudi, commenting on Karika 57, argues that a perfect God can have no need to create a world, and if God's motive is kindness, Samkhya questions whether it is reasonable to call into existence beings who while non-existent had no suffering. Samkhya postulates that a benevolent deity ought to create only happy creatures, not an imperfect world like the real world.[76]

Charvaka, originally known as Lokāyata, a heterodox Hindu philosophy states that there is "no God, no samsara (rebirth), no karma, no duty, no fruits of merit, no sin."[77] Proponents of the school of Mimamsa, which is based on rituals and orthopraxy, decided that the evidence allegedly proving the existence of God is insufficient. They argue that there is no need to postulate a maker for the world, just as there is no need for an author to compose the Vedas or a god to validate the rituals.[78] Mimamsa argues that the gods named in the Vedas have no existence apart from the mantras that speak their names. In that regard, the power of the mantras is what is seen as the power of gods.[79]

Psychological aspects

Several authors have offered psychological or sociological explanations for belief in the existence of God.

Psychologists observe that the majority of humans often ask existential questions such as "why we are here" and whether life has purpose. Some psychologists have posited that religious beliefs may recruit cognitive mechanisms in order to satisfy these questions. 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 parental figure, the obsessional nature of ritual, and the hypnotic state a community can induce as contributing factors to the psychology of religion.

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. Boyer suggests that, because of evolutionary pressures, humans err on the side of attributing agency where there isn't any. In Boyer's view, belief in supernatural entities spreads and becomes culturally fixed because of their memorability. The concept of "minimally counterintuitive" 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) leave a lasting impression that spreads through word-of-mouth.

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 produces the concept of the supernatural. Tremlin contends that an agency detection device (ADD) and a theory of mind module (ToMM) lead humans to suspect an agent behind every event. Natural events for which there is no obvious agent may be attributed to God (c.f. Act of God).

Agnosticism

Agnosticism is the view that the existence of God, of the divine or the supernatural is unknown or unknowable.The English biologist Thomas Henry Huxley coined the word agnostic in 1869, and said "It simply means that a man shall not say he knows or believes that which he has no scientific grounds for professing to know or believe."

Earlier thinkers, however, had written works that promoted agnostic points of view, such as Sanjaya Belatthaputta, a 5th-century BCE Indian philosopher who expressed agnosticism about any afterlife; and Protagoras, a 5th-century BCE Greek philosopher who expressed agnosticism about the existence of "the gods". The Nasadiya Sukta in the Rigveda is agnostic about the origin of the universe.According to the philosopher William L. Rowe, "agnosticism is the view that human reason is incapable of providing sufficient rational grounds to justify either the belief that God exists or the belief that God does not exist".Agnosticism is the doctrine or tenet of agnostics with regard to the existence of anything beyond and behind material phenomena or to knowledge of a First Cause or God, and is not a religion.

Apatheism

Apatheism (; a portmanteau of apathy and theism) is the attitude of apathy towards the existence or non-existence of god(s). It is more of an attitude rather than a belief, claim, or belief system.An apatheist is someone who is not interested in accepting or rejecting any claims that gods exist or do not exist. The existence of god(s) is not rejected, but may be designated irrelevant.Scientist and philosopher Ian von Hegner has argued that apatheism is an alternative to positions such as theism, atheism, and agnosticism, with implications that have been overlooked in modern philosophical discussions. Philosopher Trevor Hedberg has called apatheism "uncharted territory in the philosophy of religion."

Argument from a proper basis

The argument from a proper basis is an ontological argument for the existence of God related to fideism. Alvin Plantinga argued that belief in God is a properly basic belief, and so no basis for belief in God is necessary.

Argument from beauty

The argument from beauty (also the aesthetic argument) is an argument for the existence of a realm of immaterial ideas or, most commonly, for the existence of God.

Plato argued there is a transcendent plane of abstract ideas, or universals, which are more perfect than real-world examples of those ideas. Later philosophers connected this plane to the idea of goodness, beauty, and then the Christian God.

Various observers have also argued that the experience of beauty is evidence of the existence of a universal God. Depending on the observer, this might include artificially beautiful things like music or art, natural beauty like landscapes or astronomical bodies, or the elegance of abstract ideas like the laws of mathematics or physics.

The best-known defender of the aesthetic argument is Richard Swinburne.

Argument from consciousness

The argument from consciousness is an argument for the existence of God based on consciousness. The best-known defender of the argument from consciousness is J. P. Moreland.

Argument from degree

The argument from degrees or the degrees of perfection argument is an argument for the existence of God first proposed by mediaeval Roman Catholic theologian Thomas Aquinas as one of the five ways to philosophically argue in favour of God's existence in his Summa Theologica. It is based on ontological and theological notions of perfection. Contemporary Thomist scholars are often in disagreement on the metaphysical justification for this proof.. According to Edward Feser, the metaphysics involved in the argument has more to do with Aristotle than Plato; hence, while the argument presupposes realism about universals and abstract objects, it would be more accurate to say Aquinas is thinking of Aristotelian realism and not Platonic realism per se.

Argument from inconsistent revelations

The argument from inconsistent revelations, also known as the avoiding the wrong hell problem, is an argument against the existence of God. It asserts that it is unlikely that God exists because many theologians and faithful adherents have produced conflicting and mutually exclusive revelations. The argument states that since a person not privy to revelation must either accept it or reject it based solely upon the authority of its proponent, and there is no way for a mere mortal to resolve these conflicting claims by investigation, it is prudent to reserve one's judgment.

It is also argued that it is difficult to accept the existence of any one God without personal revelation. Most arguments for the existence of God are not specific to any one religion and could be applied to many religions with near equal validity. When faced with these competing claims in the absence of a personal revelation, it is argued that it is difficult to decide amongst them, to the extent that acceptance of any one religion requires a rejection of the others. Further, were a personal revelation to be granted to a nonbeliever, the same problem of confusion would develop in each new person the believer shares the revelation with.

Argument from love

The Argument from love is an argument for the existence of God. The best-known defender of the argument is Roger Scruton.

Argument from morality

The argument from morality is an argument for the existence of God. Arguments from morality tend to be based on moral normativity or moral order. Arguments from moral normativity observe some aspect of morality and argue that God is the best or only explanation for this, concluding that God must exist. Arguments from moral order are based on the asserted need for moral order to exist in the universe. They claim that, for this moral order to exist, God must exist to support it. The argument from morality is noteworthy in that one cannot evaluate the soundness of the argument without attending to almost every important philosophical issue in meta-ethics.

German philosopher Immanuel Kant devised an argument from morality based on practical reason. Kant argued that the goal of humanity is to achieve perfect happiness and virtue (the summum bonum) and believed that an afterlife must exist in order for this to be possible, and that God must exist to provide this. In his book Mere Christianity, C. S. Lewis argued that "conscience reveals to us a moral law whose source cannot be found in the natural world, thus pointing to a supernatural Lawgiver." Lewis argued that accepting the validity of human reason as a given must include accepting the validity of practical reason, which could not be valid without reference to a higher cosmic moral order which could not exist without a God to create and/or establish it. A related argument is from conscience; John Henry Newman argued that the conscience supports the claim that objective moral truths exist because it drives people to act morally even when it is not in their own interest. Newman argued that, because the conscience suggests the existence of objective moral truths, God must exist to give authority to these truths.

Contemporary defenders of the argument from morality are Graham Ward, Alister McGrath and William Lane Craig.

Argument from religious experience

The argument from religious experience is an argument for the existence of God. It holds that the best explanation for religious experiences is that they constitute genuine experience or perception of a divine reality. Various reasons have been offered for and against accepting this contention.

Contemporary defenders of the argument are Alister Hardy and Dinesh D'Souza.

Atheist's Wager

The Atheist's Wager, popularised by the philosopher Michael Martin and published in his 1990 book Atheism: A Philosophical Justification, is an atheistic response to Pascal's Wager regarding the existence of God.

One version of the Atheist's Wager suggests that since a kind and loving god would reward good deeds – and that if no gods exist, good deeds would still leave a positive legacy – one should live a good life without religion. Another formulation suggests that a god may reward honest disbelief and punish a dishonest belief in the divine.

Cosmological argument

In natural theology and philosophy, a cosmological argument is an argument in which the existence of a unique being, generally seen as some kind of god, is deduced or inferred from facts or alleged facts concerning causation, change, motion, contingency, or finitude in respect of the universe as a whole or processes within it. It is traditionally known as an argument from universal causation, an argument from first cause, or the causal argument, and is more precisely a cosmogonical argument (about the origin). Whichever term is employed, there are three basic variants of the argument, each with subtle yet important distinctions: the arguments from in causa (causality), in esse (essentiality), and in fieri (becoming).

The basic premises of all of these are the concept of causality. The conclusion of these arguments is first cause, subsequently deemed to be God. The history of this argument goes back to Aristotle or earlier, was developed in Neoplatonism and early Christianity and later in medieval Islamic theology during the 9th to 12th centuries, and re-introduced to medieval Christian theology in the 13th century by Thomas Aquinas. The cosmological argument is closely related to the principle of sufficient reason as addressed by Gottfried Leibniz and Samuel Clarke, itself a modern exposition of the claim that "nothing comes from nothing" attributed to Parmenides.

Contemporary defenders of cosmological arguments include William Lane Craig, Robert Koons, Alexander Pruss, and William L. Rowe.

God

In monotheistic thought, God is conceived of as the supreme being, creator deity, and principal object of faith. The conceptions of God, as described by theologians, commonly include the attributes of omniscience (all-knowing), omnipotence (all-powerful), omnipresence (all-present), and as having an eternal and necessary existence. Depending on one's kind of theism, these attributes are used either in way of analogy, or in a literal sense as distinct properties. God is most often held to be incorporeal (immaterial). Incorporeality and corporeality of God are related to conceptions of transcendence (being outside nature) and immanence (being in nature) of God, with positions of synthesis such as the "immanent transcendence". Psychoanalyst Carl Jung equated religious ideas of God with transcendental aspects of consciousness in his interpretation.Some religions describe God without reference to gender, while others or their translations use sex-specific terminology. Judaism attributes only a grammatical gender to God, using terms such as "Him" or "Father" for convenience.God has been conceived as either personal or impersonal. In theism, God is the creator and sustainer of the universe, while in deism, God is the creator, but not the sustainer, of the universe. In pantheism, God is the universe itself. In atheism, there is an absence of belief in God. In agnosticism, the existence of God is deemed unknown or unknowable. God has also been conceived as the source of all moral obligation, and the "greatest conceivable existent". Many notable philosophers have developed arguments for and against the existence of God.Monotheists refer to their gods using names prescribed by their respective religions, with some of these names referring to certain cultural ideas about their god's identity and attributes. In the ancient Egyptian era of Atenism, possibly the earliest recorded monotheistic religion, this deity was called Aten, premised on being the one "true" Supreme Being and creator of the universe. In the Hebrew Bible and Judaism, Elohim, Adonai, YHWH (Hebrew: יהוה‎) and other names are used as the names of God. Yahweh and Jehovah, possible vocalizations of YHWH, are used in Christianity. In the Christian doctrine of the Trinity, God, coexisting in three "persons", is called the Father, the Son, and the Holy Spirit. In Islam, the name Allah is used, while Muslims also have a multitude of titular names for God. In Hinduism, Brahman is often considered a monistic concept of God. In Chinese religion, Shangdi is conceived as the progenitor (first ancestor) of the universe, intrinsic to it and constantly bringing order to it. Other religions have names for the concept, for instance, Baha in the Bahá'í Faith, Waheguru in Sikhism, Sang Hyang Widhi Wasa in Balinese Hinduism, and Ahura Mazda in Zoroastrianism.The many different conceptions of God, and competing claims as to God's characteristics, aims, and actions, have led to the development of ideas of omnitheism, pandeism, or a perennial philosophy, which postulates that there is one underlying theological truth, of which all religions express a partial understanding, and as to which "the devout in the various great world religions are in fact worshipping that one God, but through different, overlapping concepts".

Kalam cosmological argument

The Kalām cosmological argument is a modern formulation of the cosmological argument for the existence of God; named for the kalam (medieval Islamic scholasticism), it was popularized by William Lane Craig in his The Kalām Cosmological Argument (1979).

The argument is a variant of the unmoved mover in Aristotelianism; it is named for medieval Islamic scholasticism because Craig, arguing against the possibility of the existence of actual infinities, traced the idea to 11th-century philosopher Al-Ghazali.

Since Craig's original publication, the Kalam cosmological argument has elicited public debate between Craig and Graham Oppy, Adolf Grünbaum, J. L. Mackie and Quentin Smith, and has been used in Christian apologetics.

According to Michael Martin, the cosmological arguments presented by Craig, Bruce Reichenbach, and Richard Swinburne are "among the most sophisticated and well argued in contemporary theological philosophy", while also noting that, in reference to Craig's argument specifically, "there may have been trillions of personal agents involved in the creation".The Kalam argument's underpinning is the impossibility of an actual infinite, which is what distinguishes it from other cosmological arguments such as that of Thomas Aquinas, which rests on the impossibility of an essentially ordered infinite regress, and that of Leibniz and Clark, which uses the Principle of Sufficient Reason.

Natural-law argument

Natural-law argument for the existence of God was especially popular in the eighteenth century as a result of the influence of Sir Isaac Newton. As Bertrand Russell pointed out much later, many of the things we consider to be laws of nature, in fact, are human conventions. Indeed, Albert Einstein has shown that Newton's law of universal gravitation was such a convention, and though elegant and useful, one that did not describe the universe precisely. Most true laws are rather trivial, such as mathematical laws, laws of probability, and so forth, and much less impressive than those that were envisioned by Newton and his followers. Russell wrote:

"If you say, as more orthodox theologians do, that in all the laws which God issues he had a reason for giving those laws rather than others -- the reason, of course, being to create the best universe, although you would never think it to look at it -- if there was a reason for the laws which God gave, then God himself was subject to law, and therefore you do not get any advantage by introducing God as an intermediary. You really have a law outside and anterior to the divine edicts, and God does not serve your purpose, because he is not the ultimate law-giver. In short, this whole argument from natural law no longer has anything like the strength that it used to have."The argument of natural laws as a basis for God was changed by Christian figures such as Thomas Aquinas, in order to fit biblical scripture and establish a Judeo-Christian teleological law.

Nyayakusumanjali

Nyayakusumanjali ( A Handful of Flowers of Logic) is a treatise in Sanskrit composed by 10th century CE Indian logician and philosopher Udayana. The work has been described as codification of the Hindu proof for the existence of God. It has been noted that this treatise is the most elaborate and the most fundamental work of the Nyaya-Vaiseshika school on the Isvara doctrine.

Ontological argument

An ontological argument is a philosophical argument for the existence of God that uses ontology. Many arguments fall under the category of the ontological, and they tend to involve arguments about the state of being or existing. More specifically, ontological arguments tend to start with a priori theory about the organization of the universe. If that organizational structure is true, the argument will provide reasons why God must exist.

The first ontological argument in the Western Christian tradition was proposed by Anselm of Canterbury in his 1078 work Proslogion. Anselm defined God as "that than which nothing greater can be thought", and argued that this being must exist in the mind, even in the mind of the person who denies the existence of God. He suggested that, if the greatest possible being exists in the mind, it must also exist in reality. If it exists only in the mind, then an even greater being must be possible—one which exists both in the mind and in reality. Therefore, this greatest possible being must exist in reality. Seventeenth-century French philosopher René Descartes deployed a similar argument. Descartes published several variations of his argument, each of which centred on the idea that God's existence is immediately inferable from a "clear and distinct" idea of a supremely perfect being. In the early eighteenth century, Gottfried Leibniz augmented Descartes' ideas in an attempt to prove that a "supremely perfect" being is a coherent concept. A more recent ontological argument came from Kurt Gödel, who proposed a formal argument for God's existence. Norman Malcolm revived the ontological argument in 1960 when he located a second, stronger ontological argument in Anselm's work; Alvin Plantinga challenged this argument and proposed an alternative, based on modal logic. Attempts have also been made to validate Anselm's proof using an automated theorem prover. Other arguments have been categorised as ontological, including those made by Islamic philosophers Mulla Sadra and Allama Tabatabai.

Since its proposal, few philosophical ideas have generated as much interest and discussion as the ontological argument. Nearly all of the great minds of Western philosophy have found the argument worthy of their attention, and a number of criticisms and objections have been mounted. The first critic of the ontological argument was Anselm's contemporary, Gaunilo of Marmoutiers. He used the analogy of a perfect island, suggesting that the ontological argument could be used to prove the existence of anything. This was the first of many parodies, all of which attempted to show that the argument has absurd consequences. Later, Thomas Aquinas rejected the argument on the basis that humans cannot know God's nature. Also, David Hume offered an empirical objection, criticising its lack of evidential reasoning and rejecting the idea that anything can exist necessarily. Immanuel Kant's critique was based on what he saw as the false premise that existence is a predicate. He argued that "existing" adds nothing (including perfection) to the essence of a being, and thus a "supremely perfect" being can be conceived not to exist. Finally, philosophers including C. D. Broad dismissed the coherence of a maximally great being, proposing that some attributes of greatness are incompatible with others, rendering "maximally great being" incoherent.

Contemporary defenders of the ontological argument include Alvin Plantinga, William Alston and David Bentley Hart.

Teleological argument

The teleological or physico-theological argument, also known as the argument from design, or intelligent design argument is an argument for the existence of God or, more generally, for an intelligent creator based on perceived evidence of deliberate design in the natural world.The earliest recorded versions of this argument are associated with Socrates in ancient Greece, although it has been argued that he was taking up an older argument. Plato, his student, and Aristotle, Plato's student, developed complex approaches to the proposal that the cosmos has an intelligent cause, but it was the Stoics who, under their influence, "developed the battery of creationist arguments broadly known under the label 'The Argument from Design'".Abrahamic religions have used the teleological argument in many ways, and has a long association with them. In the Middle Ages, Islamic theologians such as Al-Ghazali used the argument, although it was rejected as unnecessary by Quranic literalists, and as unconvincing by many Islamic philosophers. Later, the teleological argument was accepted by Saint Thomas Aquinas and included as the fifth of his "Five Ways" of proving the existence of God. In early modern England clergymen such as William Turner and John Ray were well-known proponents. In the early 18th century, William Derham published his Physico-Theology, which gave his "demonstration of the being and attributes of God from his works of creation". Later, William Paley, in his 1802 Natural Theology or Evidences of the Existence and Attributes of the Deity published a prominent presentation of the design argument with his version of the watchmaker analogy and the first use of the phrase "argument from design".From its beginning, there have been numerous criticisms of the different versions of the teleological argument, and responses to its challenge to the claims against non-teleological natural science. Especially important were the general logical arguments made by David Hume in his Dialogues Concerning Natural Religion, published 1779, and the explanation of biological complexity given in Charles Darwin's Origin of Species, published in 1859. Since the 1960s, Paley's arguments, including the words "intelligent design", have been influential in the development of a creation science movement, especially the form known as the intelligent design movement, which not only uses the teleological argument to argue against the modern scientific understanding of evolution, but also makes the claim that supposed flaws in evolutionary science justify removing it from the educational curriculum.Also starting already in classical Greece, two approaches to the teleological argument developed, distinguished by their understanding of whether the natural order was literally created or not. The non-creationist approach starts most clearly with Aristotle, although many thinkers, such as the Neoplatonists, believed it was already intended by Plato. This approach is not creationist in a simple sense, because while it agrees that a cosmic intelligence is responsible for the natural order, it rejects the proposal that this requires a "creator" to physically make and maintain this order. The Neoplatonists did not find the teleological argument convincing, and in this they were followed by medieval philosophers such as Al-Farabi and Avicenna. Later, Averroes and Thomas Aquinas considered the argument acceptable, but not necessarily the best argument.

Contemporary defenders of the teleological argument are Antony Flew, Richard Swinburne and John Lennox.

Transcendental argument for the existence of God

The Transcendental Argument for the Existence of God (TAG) is the argument that attempts to prove the existence of God by arguing that logic, morals, and science ultimately presuppose a supreme being and that God must therefore be the source of logic and morals.A version was formulated by Immanuel Kant in his 1763 work The Only Possible Argument in Support of a Demonstration of the Existence of God, and most contemporary formulations of the transcendental argument have been developed within the framework of Christian presuppositional apologetics.
