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.

That there could be ontologically complex concrete particulars is self-evidently true. A reductio may however be formulated which contradicts this truth. In this paper I argue that all of the reasonable ways in which we might refute this reductio will require the existence of at least some tropes.

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

This work addresses and resolved Kant's first antinomy, and brings metaphysics in line with advances in he science of big bang cosmology, introduces a new philosophical argument for the existence of a Supreme Being, and is presented in three versions, with the first version quoting Kant's most relevant remarks with regard to what he calls a science of metaphysics, and an abbreviated version without any quotes, as well as a one page abstract diagram of the argument.

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)

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)

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.

The Modal Perfection Argument (MPA) for the existence of a Supreme Being is a new ontological argument that is rooted in the insights of Anselm, Leibniz and Gödel. Something is supreme if and only if nothing is possibly greater, and a perfection is a property that it is better to have than not. The premises of MPA are that supremity is a perfection, perfections entail only perfections, and the negation of a perfection is not a perfection. I (...) do three things in this paper. First, I prove that MPA is valid by constructing a formal deduction of it in second order modal logic. Second, I argue that its premises are true. Third, I defend the argument and the logic used against some likely objections. (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)

The traditional common consent argument for the existence of God has largely been abandoned—and rightly so. In this paper, I attempt to salvage the strongest version of the argument. Surprisingly,...

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)

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)

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)

The paper presents a new version of the "Cosmological Argument" – considered to be an ontological argument, since it exclusively uses ontological concepts and principles. It employs famous results of modern physics, and distinguishes between event-causation and agent-causation. Due to these features, the argument manages to avoid the objection of infinite regress. It remains true, however, that the conclusion of the argument is too unspecific to be unambiguously considered an argument for the existence of (...) God. (shrink)

In this paper, I present a polar concept argument for the existence of abstract objects. After recalling the fundamentals concerning the debate about the existence of abstracta, I present in a detailed way the argument for the existence of abstracta. I offer two different variations of the argument: one, deductive and the other, inductive. The argument rests primarily on the fact that our universe is well-balanced. This well-balanced property results from the fact that (...) all instantiable polar dualities are instantiated. Hence, the abstract pole of the abstract/concrete duality must also be exemplified. Lastly, I review several objections that can be raised against this latter argument. (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.

The topic of our analysis is the argument for the existence of substances given by Bernard Bolzano in Athanasia, where he essentially employs two ontological categories: substance and adherence. Bolzano considers the real and conditioned Inbegriff of all adherences, which are wirklich and nicht selbst bestehen. He claims that the formed collection is dependent on something external and non-adherential, which therefore is a substance. Bolzano’s argumentation turns out to be structurally similar to his argument for the (...) class='Hi'>existence of God from Lehrbuch der Religionswissenschaft, but in each of these reasonings, we find different plausible interpretations of the key concept “Inbegriff”. The latter argumentation refers to the mereological totality of existentially conditioned objects. We propose the explication of the Bolzanian Inbegriff of all adherences using two types of predication: we consider its extension as composed of certain intensional counterparts of adherences. In our approach, we use a fragment of the theory of abstract objects formulated by E. Zalta, describing two different relations between individuals and properties: extensional exemplification and intensional encoding. We put our reconstruction in a wider context of Bolzano’s ontology, formulating the needed axioms with two primitive predicates of second order... is an adherence,... is conditioned by something real as well as the conditionally introduced first order predicate constant \ for Inbegriff of all adherential ideas. Finally, we sketch a model for our theory. (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.

This paper evaluates Richard Swinburne’s modal argument for the existence of souls. After a brief presentation of the argument, wedescribe the main known objection to it, which is called the substitution objection (SO for short), and explain Swinburne’s response to that objection. With this as background, we formalize Swinburne’s argument in a quantified propositional modal language, modifying it so that it is logically valid and contains no tacit assumptions, and we explain why we find Swinburne’s response (...) to SO unsatisfactory. Next, we indicate that, even though SO is quite compelling, a weakening of one of the premises yields a valid argument for the same conclusion which is immune to SO. This version of the argument, however, is epistemically circular. (shrink)

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-caus. (shrink)

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.

In this paper, I describe the way in which I introduce arguments for the existence of God to undergraduate students in Introduction to Philosophy.

The third Meditation is typically understood to contain two a posteriori arguments for the existence of God. The author focuses on the second argument, where Descartes proves the existence of God partly in virtue of proving that Descartes cannot be the cause of himself. To establish this, Descartes argues that if he were the cause of himself, then he would endow himself with any conceivable perfection. The justification for this claim is that bringing about a substance is (...) more difficult than creating an attribute, so anything that can do the former can do the latter. While current explanations of this justification are either implausible or inadequate, the author argues that this principle derives support from a scholastic distinction between being-as-such and determinate being. With this distinction in view, we can make sense of Descartes's argument without appealing to ambiguous or inadequate notions. (shrink)

The paper deals with the "deuteros plous", literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s "Phaedo", the key passage being Phd. 99e4–100a3. The second voyage refers to what Plato’s Socrates calls his “flight into the logoi”. Elaborating on the subject, the author first (I) provides a non-standard interpretation of the passage in question, and then (II) outlines the philosophical problem that it seems to imply, and, finally, (III) tries to apply this philosophical problem to the "ultimate (...) final proof" of immortality and to draw an analogy with the ontological argument for the existence of God, as proposed by Descartes in his 5th "Meditation". The main points are as follows: (a) the “flight into the logoi” can have two different interpretations, a common one and an astonishing one, and (b) there is a structural analogy between Descartes’s ontological argument for the existence of God in his 5th "Meditation" and the "ultimate final proof" for the immortality of the soul in the "Phaedo".

the meditations on first philosophy presents us with an alleged proof for the existence of God that proceeds from the existence of an idea of an infinite being in the human mind—an idea of God—to the existence of God himself. Insofar as we have an idea of an infinite being, an idea with “infinite objective reality,” we can legitimately ask whence it came to us. The only possible cause of this idea, claims Descartes, is an infinite being, (...) namely, God. The occurrence of just this idea in the proof is essential. In fact, Descartes maintains that any such causal proof for God’s existence crucially relies on this idea: “it seems to me that all these proofs based on his effects are reducible to a single one; and also ..

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 existence. Viewing God as the internal moral lawgiver, empowering a community of believers, is Kant’s ultimate rationale for theistic belief. (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)

Scholastic hylomorphism conceives prime matter and substantial form as metaphysical parts of every physical substance. During the early modern period, both hylomorphic constituents faced significant criticism as scientists and philosophers sought to replace Aristotelianism with physical explanations for the workings of the universe. This paper focuses specifically on prime matter and delves into the arguments put forth by four 16th-century scholastic philosophers – Toledo, Fonseca, Góis, and Suárez – in their attempts to establish the existence of prime matter. Firstly, (...) I analyse a set of arguments rooted in substantial change, which emphasize the crucial role of a persistent, common substrate in the processes of generation and corruption. Secondly, I explore a set of ex-nihilo arguments and, thirdly, I examine a series of demonstrations based on the interplay between accidental and substantial change. Although these three sets of arguments converge on the necessity of a common substrate for substantial change to occur, they fall short of demonstrating that this substrate is both prime and shared by all natural entities. Fourthly, I turn to a set of arguments centred on the impossibility of infinite regress, designed to complement those related to natural change, and I assess additional arguments that do not primarily focus on substantial change. Lastly, I draw my conclusions on these argumentative strategies to demonstrate the existence of prime matter. (shrink)

The conclusion of Shutte's argument that the Christian God exists does not follow from his premises without additional dubious premises. Furthermore, the first premise of the argument, namely that human persons depend on other persons to develop as persons is an empirical premise that cries out for empirical support that Shutte fails to supply. Alternative schemes of personal development are available but he does not show that they are mistaken. Moreover, Shutte's scheme generates a puzzle about how personal (...) development is ever possible. Finally, the theory of human nature underlying his argument is unsupported. On the other hand, the substitution of more sinister theories of human nature in his scheme would result in the conclusion that the “first cause” of personal development is a being with some attributes that conflict with the attributes of the Christian God and would involve a complete revamping of his theory of personal growth.

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 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)
