This is the text of my OBO entry on arguments for the existence of God.

This chapter argues that the outbreak of the Protestant Reformation undermined the Christian consensus that unaided human reason could prove God’s existence. As a consequence the issue of the provability of God in principle gained new prominence and had to be addressed in the first instance before entering the discussion of specific proofs of His existence. On the basis of the answers given to the preliminary question of the provability of God’s existence, the chapter discusses eighteenth-century reformulations (...) of a priori and a posteriori arguments for the existence of God, as well as new directions taken by natural theology in the late eighteenth century.

The efforts to prove God's existence in the history of thought have been one of the fundamental problems of philosophy and theology, and even the most important one. The evidences put furword to prove the existence of God constitute the center of philosophy of religion’s problems not only philosophy of religion, but also the disciplines such as theology-kalam and Islamic philosophy are also seriously concerned. When we look at the history of philosophy, it is clear that almost all (...) philosophers are interested in the evidence in favour of and against the existence of God. Especially in recent times, religious experience has often been regarded as evidence of the existence of God. Studies in the field of religious and mystical experience have put forward many arguments concerning the use of religious experience as evidence. However, this study has been limited to experience of sense and pure consciousness claims rather than examining all of these arguments. In this study firstly, the analogy between experience of sense and religious experience will be deal with, and then claims that conciousness can be emptied by a number of methods which are defended by mystics. In addition, it will be tried to defend the opinion that the mystical experiences which are the common point of the two approaches are valid. The main emphasis of the article will be that these arguments can be used as evidence for the existence of God.Summary: Religious experience - which has not been considered as one of the classical evidences regarding the existence of God before being popular by recent studies – is started to be called one of the arguments. The most important reason for not arguing religious experience among the evidences of God’s existence is that it is a personal experience and therefore contains subjective perspectives. However, many researchers, who refuse to accept the criticism raised against religious experience with restricting to subjectivity, emphasized the importance of religious experience by highlighting the objective aspects of such experiences. This emphasis was not only on its significance, but also on the fact that it had a cognitive feature and thus it could provide evidence for the existence of God. The argument of religious experience is generally defined as an effort for demonstrating to existence of God with reference to several feelings such as spiritual experiences of human in face of creator and sacred Being, encounter with God, uniting, and annihilating selfness in Him. The emergence of such efforts, especially after the XVIIIth century, indicates that the history of the evidence does not go back much earlier. However, even if notas evidence, it is possible to extend the traces of religious and mystical experience to the history of religions such as Buddhism and Hinduism. Considering a great amount of the previous literature focused on religious experience in the West, It is easily seen that such research is still new. The main purpose in addressing such a controversial issue is to make the argument on the religious experience more current and to show whether the religious experience would be able to use as evidence for the existence of God.First title of this study comprises many different claims such as Walter T. Stace’s The Argument from Unanimity Richard Swinburne’s The Principle of Credulity, William P. Alston’s Perceiving God, John Hick’s Experience-as. However, instead of briefly giving out very different claims, the study chooses to focus on two arguments which are less discussed and can be given in more detail. The first is the argument based on the analogy between the religious experience and the sense experience. The fundamental point of this argument is sense experience. With reference to the similarities between the sense experience and the religious experience, it can be argued that religious experience is also cognitive and may function as an evidence for the existence of God. In other words, being perceptual and noetic, namely cognitive, of sense experience is addressed as a similar side of religious experience. Whether it is imaginary or real, eventually, it is necessary for an experience to have an object and being experience of something. Therefore, the religious experience includes the perception of a Transcendent Being that is beyond and in excess of the individual who experiences. Perception of the sense experience will definitely be different from the perception of religious experience. Researchers who think that the five sense organs do not run the perception of Sacred Beings, identified broader and various meanings for the perception. Thereby, in this approach, where the semantic field of perception is expanded, it was contended that human beings were able to perceive the transcendent, eternal, and unlimited God, and this can be explained in the epistemological sense. In order to use religious experiences as an evidence for the existence of God, it is necessary to determine whether such experiences are caused by God rather than something else. This raises the issue of the validity of religious experience. The researchers in this area have propounded various criteria to identify whether religious experience is existed or not. Experiences, which do not meet the criteria, are not considered existed even if they claim to be religious experience.The second is the argument that discusses whether it is possible to suggest an evidence for the existence of God by utilizing pure consciousness events. In general, this argument claims that the consciousness gets clear, and thus, mystic or Sufi experiences the Divine One with pure consciousness by discharging consciousness from all sensual contents and removing it from secular desire and wishes. The argument, which claims the experience of Divine One is direct, therefore uninterpretable, and experienced by pure consciousness, believes clearing the consciousness of mystics from sensual qualities such as seeing, hearing, and tasting. It is stated that it is possible for mystics to empty their sensory images and get rid of them, and thus, their desires and wishes could be lost. Especially, the thinkers who are connected with the philosophy of perennialism and defend this approach, thought that people, who have distinct religion, culture, and beliefs in different parts of the world and in various time periods, had the same experience and considered such experiences were universal by suggesting that this similarity could be called as common essence.Even though the claim which offers that the events of pure consciousness are the same everywhere have been criticized in many respects, the advocates of this approach have argued that the experience has the common essence, but the interpretation is different. This relationship, which was tried to be established between experience and commentary, caused a lot of work for both the thinkers who put forward the claims of pure consciousness and the researchers who opposed it. However, examining the relationship between experience and interpretation requires serious studies in socio-psychological, cultural and religious fields. Therefore, in order not to exceed the limits of the article, the relationship between experience and interpretation is briefly mentioned.While discussing two arguments, the main claims of the arguments were addressed, and the criticisms directed to this argument were not discussed as much as possible. However, some fundamental criticisms have been mentioned shortly for a better understanding of the discussion. Since such western-oriented claims mostly were deployed in a western context, the study excluded the comparison of the claims across different cultures. (shrink)

RESUMO: O objetivo deste artigo é examinar o que entendemos ser uma prova original da existência de Deus na obra de Pierre Duhem. Cremos que a originalidade dessa prova consiste especialmente nas premissas usadas pelo filósofo. Quanto à forma, a mesma assemelha-se ao conhecido argumento do desígnio, mas a sua versão se caracteriza por buscar na história das teorias físicas a matéria da qual a existência de uma Providência é derivada. É a complexa evolução das teorias e, a despeito dela, (...) a sua espantosa progressividade em direção a estágios sempre mais perfeitos que servem de premissa para a via duhemiana de acesso a Deus. Tudo se passa como se houvesse uma suposta pré-ordenação divina do curso das teorias, uma finalidade intrínseca a ele. ABSTRACT: The aim of this paper is to examine what we believe to be an original proof of the existence of God in the work of Pierre Duhem. We think that the originality of this proof consists especially in the assumptions used by the French philosopher in his argumentation. Regarding the form, it resembles the well-known design argument, but his version is characterized by seeking in the history of physical theories the matter from which the existence of a Providence is derived. It is the complex evolution of theories and, despite it, its amazing progress towards ever more perfect theories that serves as the premise for Duhem's way of access to God. Everything goes as if it had been a divine preordainment and an intrinsic goal ruling the evolution of theories. (shrink)

Roughly speaking, Augustine claims that ‘Immutable Truth’ is superior to the human mind and, consequently a legitimate candidate for the role of God. Clearly there is such a thing as Immutable Truth. So either that is God, or there is something superior to Immutable Truth, and that superior thing is God. I spell out this argument, and offer some objections to it.

This essay discusses and criticizes Richard Swinburne's inductive argument for the existence of God. In his The Existence of God, Swinburne aims at showing that the existence of God is more probable than not. This is an argument taking into consideration the premises of all traditional arguments for the existence of God. Swinburne uses the phenomena and events that constitute the premises of these arguments as evidence in an attempt to show that his hypothesis (...) is more probably true than nor. Swinburne pursues this task by way of applying Bayes' theorem. The aim of this essay is normative - to judge the strength of Swinburne's argument for the existence of God. My primary objections towards Swinburne is that he professes a subjective concept of probability, that he relies too heavily on simplicity as a virtue of plausible and probable hypotheses and that his concept of God involves an incoherent picture of God's nature. I question not only the actual success of Swinburne's project but what his argument, if it had been successful, would have been able to establish. (shrink)

In an inductive argument data increase the probability of a hypothesis insofar as the hypothesis makes probable the data, the data are otherwise not likely to occur, and the hypothesis is simple. The cosmological argument from the existence of the universe, the teleological argument from its conformity to natural law, and other arguments from more detailed features of the universe each increase the probability that there is a God. I thus summarize in a simple form the main points (...) of my book The Existence of God. (shrink)

I offer a new deductive formulation of the Moral Argument for the existence of God which shows how one might argue for the conclusion that, if one affirms moral realism (traditionally understood as a metaethical view which acknowledges the existence of objective moral truths), one should affirm theism. The new formulation shows that these objective moral truths are either brute facts, or they are metaphysically grounded in an impersonal entity, a non-divine personal entity, or a divine personal entity (...) i.e., God. I illustrate how the alternatives to God can in principle be excluded based on the essential characteristics of those alternative hypotheses and of certain objective moral truths. I demonstrate that my deductive formulation is better than other formulations, and that it is helpful for future work on the Moral Argument. (shrink)

It is often thought that, although Spinoza develops a bold and distinctive conception of God (the unique substance, or Natura Naturans, in which all else inheres and which possesses infinitely many attributes, including extension), the arguments that he offers which purport to prove God’s existence contribute nothing new to natural theology. Rather, he is seen as just another participant in the seventeenth century revival of the ontological argument initiated by Descartes and taken up by Malebranche and Leibniz among (...) others. That this is the case is both puzzling and unfortunate. It is puzzling because although Spinoza does offer an ontological proof for the existence of God, he also offers three other non‐ontological proofs. It is unfortunate because these other non‐ontological proofs are both more convincing and more interesting than his ontological proof. In this paper, I offer reconstructions and assessments of all of Spinoza’s arguments and argue that Spinoza’s metaphysical rationalism and his commitment to something like a Principle of Sufficient Reason are the driving force behind Spinoza’s non‐ontological arguments.

I propose a new argument for the existence of God. God is defined as a conscious being that is the first cause of reality. In its simplified initial form, the argument has two premises: all possible truths are knowable, and it is impossible to know that the proposition that God does not exist is true. From and it follows that the proposition that God exists is necessarily true. After introducing the argument in its crude initial form and laying out (...) the core intuitions behind its premises, I point to two difficulties that this simplified version faces. I then go on to show how the argument can be revised to handle these difficulties. I defend the revised argument from various objections. (shrink)

After reviewing Kant’s well-known criticisms of the traditional proofs of God’s existence and his preferred moral argument, this paper presents a detailedanalysis of a densely-packed theistic argument in Religion within the Bounds of Bare Reason. Humanity’s ultimate moral destiny can be fulfilled only through organized religion, for only by participating in a religious community (or “church”) can we overcome the evil in human nature. Yet we cannot conceive how such a community can even be founded without presupposing God’s (...) class='Hi'>existence. Viewing God as the internal moral lawgiver, empowering a community of believers, is Kant’s ultimate rationale for theistic belief. (shrink)

According to the Nomological Argument, observed regularities in nature are best explained by an appeal to a supernatural being. A successful explanation must avoid two perils. Some explanations provide too little structure, predicting a universe without regularities. Others provide too much structure, thereby precluding an explanation of certain types of lawlike regularities featured in modern scientific theories. We argue that an explanation based in the creative, intentional action of a supernatural being avoids these two perils whereas leading competitors do not. (...) Although our argument falls short of a full defense, it does suggest that the Nomological Argument is worthy of philosophical attention. (shrink)

In a recent article, Emanuel Rutten has presented a novel argument for the existence of God, defined as a personal being that is the first cause of reality. An interesting feature of the argument, which caused quite a stir, is that it does not fall within any of the traditional categories of arguments for God’s existence. Rutten calls his argument a modal-epistemic one, which reflects the fact that the first premise of his argument states that all possible (...) truths are knowable. The main purpose of this article is a simple one: to point out that Rutten’s modal-epistemic argument is flawed. (shrink)

This essay tries to show that there exist several passages where Kierkegaard (and his pseudonyms) sketches an argument for the existence of God and immortality that is remarkably similar to Kant's so-called moral argument for the existence of God and immortality. In particular, Kierkegaard appears to follow Kant's moral argument both when it comes to the form and content of the argument as well as some of its terminology. The essay concludes that several passages in Kierkegaard overlap significantly (...) with Kant's moral argument, although Kierkegaard ultimately favors revealed faith over natural theology in general and Kant's moral faith in particular. Whereas Kant uses the moral argument to postulate the existence of God and immortality, Kierkegaard mainly uses it as a reductio ad absurdum of non-religious thinking. (shrink)

Some believe that evidence for the big bang is evidence for the existence of god. Who else, they ask, could have caused such a thing? In this paper, I evaluate the big bang argument, compare it with the traditional first-cause argument, and consider the relative plausibility of various natural explanations of the big bang.

In this article, I discuss Leibniz's interpretation of the cosmological argument for the existence of God. In particular, I consider whether Leibniz's position on this point was developed partly in reference to Spinoza's position. First, I analyze Leibniz's annotations from 1676 on Spinoza's Letter 12. The traditional cosmological argument, as found in Avicenna and Saint Thomas for example, relies on the Aristotelian assumption that an actual infinite is impossible and on the idea that there can be no effect without (...) a cause. From these premises, the argument concludes that God must be the uncaused first cause of all things. In Letter 12, Spinoza follows Chasdai Crescas and rejects this proof. Instead, he develops a variant of the cosmological argument which depicts God as the self-caused ground of all causes or things. In his annotations, Leibniz agrees with Spinoza about the inadequacy of the traditional argument, but remains ambiguous as to Spinoza's conception of God as a self-caused being. Next, I turn to Leibniz's comments from 1678 on Spinoza's Ethics. Here, Leibniz develops an original interpretation of the cosmological argument based entirely on the consideration of conceptual relations. Leibniz's argument depicts God as an uncaused being conceived through itself which is the condition of conceivability of all things. I argue that Leibniz developed this argument in deliberate opposition to Spinoza's conception of God as the self-caused ground of all causes or things. (shrink)

This book focuses on thinking about moral argument for the existence of God in modern philosophy, discussing the theories, the difficulties and the development of the views, which could be found in theistic proofs, especially of C. S. Lewis. As a result, the case for or against Christian faith should be evaluated in terms of the total system.

Aquinas’s name is practically synonymous with attempts at proving the existence of God. In this article I offer an interpretation and defense of a much neglected argument from Aquinas’s works, that of De Ente et Essentia Cap. IV. Therein Aquinas presents quite a youthful and in my view compelling argument for the existence of God. To begin with, I present an interpretation of the argument and on the basis of this interpretation I suggest that the argument has a (...) prima facie plausibility to it. Thereafter I consider several criticisms that are relevant to the argument, yet not compelling in my view. I conclude that the argument from the De Ente survives the criticisms leveled against it in this paper, in which case if one accepts the methodological framework that Aquinas adopts, then one ought to accept that Aquinas’s argument for God in the De Ente succeeds in what it sets out to do: to establish the existence of a single, immaterial, self-subsisting act of being, which we understand to be God.

Einstein argued in his latter years that the intelligibility of the world was in the nature of a miracle, and that in no way could one have expected a priori such a high degree of order; this is why he rejected the atheist, positivist standpoint, and believed in a Spinozist God. Einstein's argument, however, is essentially a form of the ?argument from design? for a personal God based on the existence of beautiful, mathematically simple laws of nature; that physical (...) order is a unique, improbable alternative compared to the infinite number of chaotic universes that might have existed. Einstein, in his early manhood, was a Humean, but in later years, as he moved toward Spinoza, from phenomenalism to noumenalism, he clearly rejected Hume's restriction of probable inferences to observed sequences. Darwin's arguments against biological design did not apply to Einstein's argument, because the laws of physics are not the outcome of any cumulative struggle for existence and natural selection. Perhaps the beautiful simplicity of basic physical laws helps account for the fact that relatively more physicists than biologists or psychologists hold to a theistic standpoint. Einstein's finite universe would have seriously weakened the argument that life, though infinitely improbable, would have been realized in an infinite world. But in any case, Einstein would have regarded ?emergence? theories of life as irrational. In accordance with the principle of identity of Emile Meyerson, the epistemologist whom he most respected, it would have followed that the occurrence of consciousness and intelligence was grounded in a God with those attributes, and that theism was consequently the basis for scientific knowledge.
