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 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.

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.

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)

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

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)

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,...

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.

1. The relationship established between God and possibility on the one hand and the aspect of realization on the other is, in a way, an explication of the Aristotelian position. Though Professor Weiss does not proceed along strict Aristotelian lines--in view of the fact that he does not put forth the doctrine that realization has to precede possibility--he still holds an Aristotelian view in the sense that for him possibility has no self-sufficient, independent ontological status, but must find its supplement (...) and complement in reality--in this context, in God.

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)

Much of the discussion had focussed on the question of whether religious experiences are veridical, but then Richard M. Gale asked a more fundamental question: Are they even cognitive? An experience is cognitive if it takes an intentional accusative, such as “red cube” in “I see a red cube,” as opposed to the cognate accusative exemplified by the use of the word “waltz” in “I am dancing a waltz” which is synonymous with “I am dancing waltzily.” Cognitive experiences are objective (...) in the sense that they purport the existence of an object whose..

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 ..

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)

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)

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)

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 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)

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 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)

The neuroscientists Eugene d'Aquili and Andrew Newberg, in addition to defending an empirically fruitful model of mystical experiences, argue that such experiences constitute evidence for the existence of a transcendent reality, which they call "Absolute Unitary Being." D'Aquili and Newberg point out that mystical experiences carry with them a vivid sense of reality, and that they involve characteristic forms of brain activity, just like perceptions of objects in ordinary waking consciousness. Their argument for Absolute Unitary Being fails, however, (...) since the vivid sense of reality of an experience is not the sole criterion by which to judge its veridicality, since the object of mystical experiences cannot be confirmed by independent observers, and since there is no evidence for a mechanism by which mystics experience a transcendent reality.
