Although separated by the centuries, Anselm and Hegel represent two different developments of the ontological proof. This book guides the reader through an exploration of the perplexing ontological argument from a well-balanced analysis of the works of two significant, yet polar opposite thinkers, Anselm and Hegel.

The core idea of the ontological proof is to show that the concept of existence is somehow contained in the concept of God, and that therefore God’s existence can be logically derived—without any further assumptions about the external world—from the very idea, or definition, of God. Now, G.W. Leibniz has argued repeatedly that the traditional versions of the ontological proof are not fully conclusive, because they rest on the tacit assumption that the concept of God is possible, i.e. free from (...) contradiction. A complete proof will rather have to consist of two parts. First, a proof of premiseGod is possible. Second, a demonstration of the “remarkable proposition”If God is possible, then God exists. The present contribution investigates an interesting paper in which Leibniz tries to prove proposition. It will be argued that the underlying idea of God as a necessary being has to be interpreted with the help of a distinguished predicate letter ‘E’ as follows:\\). Proposition which Leibniz considered as “the best fruit of the entire logic” can then be formalized as follows:\) \rightarrow \, E)\). At first sight, Leibniz’s proof appears to be formally correct; but a closer examination reveals an ambiguity in his use of the modal notions. According to, the possibility of the necessary being has to be understood in the sense of something which possibly exists. However, in other places of his proof, Leibniz interprets the assumption that the necessary being is impossible in the diverging sense of something which involves a contradiction. Furthermore, Leibniz believes that an »impossible thing«, y, is such that contradictory propositions like \\) and \\) might both be true of y. It will be argued that the latter assumption is incompatible with Leibniz’s general views about logic and that the crucial proof is better reinterpreted as dealing with the necessity, possibility, and impossibility of concepts rather than of objects. In this case, the counterpart of turns out to be a theorem of Leibniz’s second order logic of concepts; but in order to obtain a full demonstration of the existence of God, the counterpart of, i.e. the self-consistency of the concept of a necessary being, remains to be proven.

In Ontological Aspects of Early Jewish Anthropology, Tyson L. Putthoff combines contemporary theory and sound exegesis to understand early Jewish beliefs about how the human self reacts ontologically in God s presence.".

This book re-examines Anselm's famous arguments for the existence of God in his Proslogion, and in his Reply. It demonstrates how he validly deduces from plausible premises that God so truly exists that He could not be thought not to exist. Most commentators, ancient and modern, wrongly located his argument in a passage which is not about God at all. It becomes evident that, consequently, much contemporary criticism is based on misreading and misunderstanding his text. It reconstructs his reasoning through (...) three distinct but logically connected stages. It shows that, even if Anselm's crucial premises are sceptically interpreted, his conclusions still follow. Properly understood, this argument is not vulnerable to the standard criticisms, including Gaunilo's 'Lost island' counter-example. (shrink)

Shortly after the appearance of the Critique of Pure Reason, Kant’s claim that the ontological proof of God’s existence contains all the probative force of the cosmological argument was discussed at great length by J. F. Flatt, J. F. v. Abel and J. A. Eberhard. These early criticisms do not seem to have received the attention they deserve, even though they are extremely relevant, cogent, and difficult to dispute. Regardless of whether their assumptions are accepted, these objections point out certain (...) obscurities and flaws in Kant’s argument, casting doubt, from a logical standpoint, on the success of the main Kantian criticism of the cosmological proof.

The Hegel Lectures Series Series Editor: Peter C. Hodgson Hegel's lectures have had as great a historical impact as the works he himself published. Important elements of his system are elaborated only in the lectures, especially those given in Berlin during the last decade of his life. The original editors conflated materials from different sources and dates, obscuring the development and logic of Hegel's thought. The Hegel Lectures series is based on a selection of extant and recently discovered transcripts and (...) manuscripts. Lectures from specific years are reconstructed so that the structure of Hegel's argument can be followed. Each volume presents an accurate new translation accompanied by an editorial introduction and annotations on the text, which make possible the identification of Hegel's many allusions and sources. Lectures on the Proofs of the Existence of God Hegel lectured on the proofs of the existence of God as a separate topic in 1829. He also discussed the proofs in the context of his lectures on the philosophy of religion (1821-31), where the different types of proofs were considered mostly in relation to specific religions. The text that he prepared for his lectures in 1829 was a fully formulated manuscript and appears to have been the first draft of a work that he intended to publish and for which he signed a contract shortly before his death in 1831. The 16 lectures include an introduction to the problem of the proofs and a detailed discussion of the cosmological proof. Philipp Marheineke published these lectures in 1832 as an appendix to the lectures on the philosophy of religion, together with an earlier manuscript fragment on the cosmological proof and the treatment of the teleological and ontological proofs as found in the 1831 philosophy of religion lectures. Hegel's 1829 lectures on the proofs are of particular importance because they represent what he actually wrote as distinct from auditors' transcriptions of oral lectures. Moreover, they come late in his career and offer his final and most seasoned thinking on a topic of obvious significance to him, that of the reality status of God and ways of knowing God. These materials show how Hegel conceived the connection between the cosmological, teleological, and ontological proofs. All of this material has been newly translated by Peter C. Hodgson from the German critical editions by Walter Jaeschke. This edition includes an editorial introduction, annotations on the text, and a glossary and bibliography. (shrink)

This paper argues that there is only one proof for God’s existence in Avicenna, and only one way for establishing the proof within his metaphysical system. This metaphysical proof is essentially derived from a priori notions, among which the notion of existence has the central role. Avicenna’s proof is structured in such a way that all its concepts are either derived from the meaning of ‘existence’ or are connected with this meaning. In this sense Avicenna’s proof sets out a scenario (...) of discursive a priori knowledge established purely on considerations of fundamental ontological meanings such as ‘existence’, ‘existent’, ‘thing’, ‘necessary’, ‘possible’, ‘impossible’, ‘one’ and ‘cause’.

The possibility of proving the existence of God has fascinated thinkers and believers throughout the centuries. For those like Richard Swinburne, such a project is both worthwhile and successful. For others, like D. Z. Phillips, it is wholly inappropriate. Most critics have simply taken sides at this point; but this book argues a way forward, showing that the disparity between Swinburne and Phillips goes deeper - questioning the fundamental nature of God, the meaning of religious language, and the proper task (...) of philosophy. The author argues that behind each thinker's work, and their attitudes towards proving the existence of God, lies fundamental trust. A positive discussion of relativism leads to a fresh analysis of the arguments for God's existence, particularly the ontological argument: Dr Messer shows that these are worthwhile - although not for the traditional reasons.

This is one of Barth's most important works - far more important than may appear at first sight.... Here we have not merely one great theologian taking the measure of another. That in itself would be interesting enough. But in addition to that we are here shown one great theologian clarifying and crystallizing, in conversation with another, his own ideas as to the nature of theology and of the theologian's task.

A resurgence of scholarly work on proof of God?s existence is noticeable over the past decade, with considerable emphasis on attempts to provide?analytic proof? based on the meanings and logic of various identity statements which constitute premises of the syllogisms of the?proof?. Most recently perhaps, Emmanuel Rutten?s?modal-epistemic proof? has drawn serious academic attention. Like other?analytic? and strictly logical proofs of God?s existence, Rutten?s proof has been found flawed. In this paper I discuss the possibility of an?ethics-based? identity proof of God?s (...) existence. Such a proof, the first version of which, I believe, has been offered, indirectly, by Nikolai Lossky, utilizes the form and structure of the analytic proof, but fundamentally rests on the perception of moral values we associate with God and Godliness. The nature of the proof shifts the focus of the very attempt to?prove? God?s existence from what I believe is an unreasonable standard, unattainable even in?proving? the existence of the more mundane world, towards a more functional, practical and attainable standard. The proof proposed initially by Lossky, and in a more systematic form here, I believe, shows the indubitable existence of God in the sense of his moral presence in the lives of the faithful, at least with the same degree of certainty as the presence or?existence? of anything else that can be epistemically proven in principle.

This paper argues that an examination of the ontology that underpins Descartes’s Fifth Meditation ontological proof of God’s existence will contribute to a better understanding of the nature and structure of the proof. Attention to the Cartesian meditator’s development of this ontology in earlier meditations also makes clear why this proof could not have been asserted before the Fifth Meditation. Finally, it is argued that Kant’s objections against the ontological proof have no force against Descartes’ particular version of the proof.

Two questions concerning Anselm of Canterbury’s theistic argument provided in Proslogion Ch. 2 are asked and answered: is the argument valid? under what conditions could it be sound? In order to answer the questions the argument is formalized as a first-order theory called AP2. The argument turns out to be valid, although it contains a hidden premise. The argument is also claimed not to be ontological one, but rather an a posteriori argument. One of the premises is found to be (...) false, so the argument is claimed not to be sound and to fail to prove its conclusion. (shrink)

"I began to ask myself whether there might be found a single argument which would require no other for its proof than itself alone, and would suffice to demonstrate that God truly exists." - St. Anselm.

In this book, Richard Campbell reformulates Anselm’s proof to show that factual evidence confirmed by modern cosmology validly implies that God exists. Anselm’s proof, which was never the “ontological argument” attributed to him, emerges as engaging with current philosophical issues concerning existence and scientific explanation.

We argue that Descartes’s theistic proofs in the ’Meditations’ are much simpler and straightforward than they are traditionally taken to be. In particular, we show how the causal argument of the "Third Meditation" depends on the intuitively innocent principle that nothing comes from nothing, and not on the more controversial principle that the objective reality of an idea must have a cause with at least as much formal reality. We also demonstrate that the so-called ontological "argument" of the "Fifth Meditation" (...) is best understood not as a formal proof but as an axiom, revealed as self-evident by analytic meditation.

Now it cannot be denied, I think, that this argument has the appearance of being sound, that is, both true in its premises and valid in its conclusion. But one surely ought to harbor suspicions concerning an argument which establishes the most momentous of all conclusions upon nothing more than a few propositions. In this paper I shall attempt to show that these suspicions are well-founded by pointing out that the above "proof" derives whatever force it has from an equivocation.

The ontological argument is one of the most intriguing lines of reasoning in Western thought. Leaving behind debates over the proper relation between science and religion, it makes a simple move from conceptual analysis to existence in order to prove the existence of god. The ontological argument will be reviewed against the background of the contemporary debate on thought experiments. Assuming that the ontological argument fails as a philosophical proof, I will argue that its move from concept to existence might (...) best be understood as a thought experiment of revealed theology (a theology based on revelation – unlike philosophical theology/natural theology). Viewed from this perspective it makes sense that Anselm of Canterbury offered his versions of the ontological argument in the form of a prayer, which, presupposing the existence of god, seems to run counter to a proof of god's existence.

When abstracted from the individual’s practical religious life, that is, from the experience of prayer, worship, and the like, mind’s awareness of God cannot be understood. Resorting mainly to Anselm, Augustine, Thomas Aquinas, and Descartes, Collingwood argues that the externality of the Platonic absolute is that of an absolute transcendent whereas the Christian God is not only conceived as the transcendent cause of all things, but also as the immanent spirit in them. By asserting the unity of the mind—regarded as identical with its acts—this interpretation is meant to serve both as a means towards self-knowledge, and as a starting point for a future conceptual unification of religion and philosophy.

Proofs of God in Early Modern Europe offers a fascinating window into early modern efforts to prove God’s existence. Assembled here are twenty-two key texts, many translated into English for the first time, which illustrate the variety of arguments that philosophers of the seventeenth and eighteenth centuries offered for God. These selections feature traditional proofs—such as various ontological, cosmological, and design arguments—but also introduce more exotic proofs, such as the argument from eternal truths, the argument from universal aseity, and the (...) argument ex consensu gentium. Drawn from the work of eighteen philosophers, this book includes both canonical figures (such as Descartes, Spinoza, Newton, Leibniz, Locke, and Berkeley) and noncanonical thinkers (such as Norris, Fontenelle, Voltaire, Wolff, Du Châtelet, and Maupertuis). -/- Lloyd Strickland provides fresh translations of all selections not originally written in English and updates the spelling and grammar of those that were. Each selection is prefaced by a lengthy headnote, giving a biographical account of its author, an analysis of the main argument(s), and important details about the historical context. Strickland’s introductory essay provides further context, focusing on the various reasons that led so many thinkers of early modernity to develop proofs of God’s existence. -/- Proofs of God is perfect for both students and scholars of early modern philosophy and philosophy of religion.

Brian Leftow offers a theist theory of necessity and possibility, and a new sort of argument for God's existence. He argues that necessities of logic and mathematics are determined by God's nature, but that it is events in God's mind - his imagination and choice - that account for necessary truths about concrete creatures.

I do not think that the existence of God can be proved or even that the main justification for the belief can be found in argument in the ordinary sense of that term, but I think two of the three which have, since Kant at least, been classified as the traditional arguments of natural theology have some force and are worthy of serious consideration. This consideration I shall now proceed to give. I cannot say this of the remaining one of (...) the arguments, the ‘ontological proof’, which I shall therefore not discuss here. (shrink)

In this article I show how Schelling elaborates the fundamental topic of the ontological proof, from the first phase of his philosophy on. I make clear how he keenly penetrates the formulation of Descartes, establishing that it is insufficient in order to demonstrate the existence of God. The fact is, Descartes says that it would be contradictory with the nature of the prefect being that he existed only accidentally; so that it can exist only necessarily. But it is different to (...) say that God can exist only necessarily, and to say that He, in fact, exists necessarily. From the first sentence, descends only that He exists necessarily if He exists, but this does not imply that He exists in fact. To arrive to the existence, the only possible way is through experience: the reason gives the concept, the experience gives the existence. On this difference is based the hendiadys between negative and positive philosophy, the nature of which I cleared up in the last part of the article. (shrink)

This work is a review of the book by Stephen T. Davis “God, Reason, and Theistic Proofs". The author discusses some methodological, logical and ontological advantages and disadvantages of this book as well as some features related to the translation of the book into Russian. The analysis is presented here not in chronological (chapter by chapter), but in a thematic order that enables the reader to get quickly acquainted with topics and problems considered in the book.

The series offers a publication forum for innovative works on all topics of analytic philosophy. The focus is on the disciplines of theoretical philosophy: metaphysics, ontology, epistemology, philosophy of language, logic. Furthermore, works that additionally include contributions to the history of philosophy are also welcome.

This chapter contains sections titled: Hegel's Discussion of the Proofs On “Proof” and “Existence” The Proofs, Religious Elevation, and the Communion of Spirit The Multiplicity of Proofs and the One God The Cosmological Proof The Teleological Proof The Ontological Proof The Dialectic of the Proofs and the Speculative Reversal Hegel's Proofs Today.

The proposition that the existence of God is demonstrable by rational argument is doubted by nearly all philosophical opinion today and is thought by most Christian theologians to be incompatible with Christian faith. This book argues that, on the contrary, there are reasons of faith why in principle the existence of God should be thought rationally demonstrable and that it is worthwhile revisiting the theology of Thomas Aquinas to see why this is so. The book further suggests that philosophical objections (...) to proofs of God's existence rely upon an attenuated and impoverished conception of reason which theologians of all monotheistic traditions might wish to reject. Denys Turner proposes that on a broader and deeper conception of it, human rationality is open to the 'sacramental shape' of creation as such and in its exercise of rational proof of God it in some way participates in that sacramentality of all things.

Kurt Gödel’s version of the Ontological Proof derives rather than assumes the crucial Possibility Claim: the claim that it is possible that something God-like exists. Gödel’s derivation starts off with a proof of the Possible Instantiation of the Positive: the principle that, if a property is positive, it is possible that there exists something that has that property. I argue that Gödel’s proof of this principle relies on some implausible axiological assumptions but it can be patched so that it only (...) relies on plausible principles. But Gödel’s derivation of the Possibility Claim also needs a substantial axiological assumption, which is still open to doubt. (shrink)

Can God be the efficient cause of himself (causa sui,)? It is well known that Descartes answers this question in the affirmative, but it is considerably less clear why. The main contention of the essay is that Descartes advances the causa sui doctrine because he came to think that the ontological proof of Meditation V required it. We argue these contentions through a close analysis of Descartes' initial articulation of causa sui in response to Caterus, followed by attention to the (...) reformulation of the doctrine in response to the logical objections posed by Arnauld. Our understanding of causa sui as a move made within the horizon of the ontological proof not only illuminates why Descartes would have defended a doctrine as conceptually problematic as causa sui, but also provides an alternative to Jean-Luc Marion's view that causa sui constitutes a third, distinct proof for the existence of God. /// Pode Deus ser a causa eficiente de si mesmo (causa sui,)? É bem sabido que Descartes responde aflrmativamente a esta questão, mas é consideravelmente menos claro porquê. O principal conteúdo do ensaio é que Descartes apresenta a doutrina da causa sui porque pensou que a prova ontológica da Meditação V precisava dela. Demonstramos estas afirmações através de uma análise rigorosa da articulação inicial de Descartes da causa sui em resposta a Caterus, seguida de uma atenção à reformulação da doutrina em resposta às objecções logicas apresentadas por Arnauld. A nossa compreensão da causa sui como proposta feita no horizonte da prova ontológica não ilumina apenas porque é que Descartes teria defendido uma doutrina conceptualmente tão problemática como a causa sui, mas também providencia uma alternativa ao ponto de vista de Jean-Luc Marion de que a causa sui constitui a terceira, prova distintapara a existência de Deus.

In recent years, the ontological argument and theistic metaphysics have been criticised by philosophers working in both the analytic and continental traditions. Responses to these criticisms have primarily come from philosophers who make use of the traditional, and problematic, concept of God. In this volume, Daniel A. Dombrowski defends the ontological argument against its contemporary critics, but he does so by using a neoclassical or process concept of God, thereby strengthening the case for a contemporary theistic metaphysics. Relying on the (...) thought of Charles Hartshorne, he builds on Hartshorne's crucial distinction between divine existence and divine actuality, which enables neoclassical defenders of the ontological argument to avoid the familiar criticism that the argument moves illegitimately from an abstract concept to concrete reality. His argument, thus, avoids the problems inherent in the traditional concept of God as static. (shrink)

Caramuels’ proof of non-existence of God is compared with Gödel’s proof of existence.

Anderson-like ontological proofs, studied in this paper, employ contingent identity, free principles of quantification of the 1st order variables and classical principles of quantification of the 2nd order variables. All these theories are strongly complete wrt. classes of modal structures containing families of world-varying objectual domains of the 1st order and constant conceptual domains of the 2nd order. In such structures, terms of the 1st order receive only rigid extensions, which are elements of the union of all 1st order domains. (...) Terms of the 2nd order receive extensions and intensions. Given a family of preselected world-varying objectual domains of the 2nd order, non-rigid extensions of the 2nd order terms belong always to a preselected domain connected with a given world. Rigid intensions of the 2nd order terms are chosen from among members of a conceptual domain of the 2nd order, which is the set of all functions from the set of worlds to the union of all 2nd order preselected domains such that values of these functions at a given world belong to a preselected domain connected with this world.

Kant’s objection to the ontological argument in the first Critique is thought to be contained within the claim that ‘existence is not a predicate’. This article maintains that this ‘digression’ on existence is not Kant’s main objection. Instead, Kant argues within the first eight paragraphs of this fourteen paragraph section that there is no meaningful predication – either logical or real – without a synthetic, existential judgment concerning the subject of predication. Thus, the very subject of predication of the proof (...) (God) is an empty concept and an indeterminate nominal definition (rather than a real possibility) that allows for neither meaningful predication nor the generation of a contradiction. I argue that this objection is significantly different than classical objections that are often identified with it and from Kant’s objection in 1763. I also argue that Kant’s target is not simply the Cartesian argument but is also his own pre-critical onto-theological argument. There is little evidence that Kant continues to accept the a priori onto-theological argument, and, in fact, he rejects its core claims in his discussion of the ontological argument and in the final paragraphs of the section on the Ideal of Reason.

In the fifth of his Meditations on First Philosophy, Descartes offers a version of the ontological proof for the existence of God. As Caterus argues in the First Objections, however, it seems that if this argument were valid, then so also would be any number of absurd arguments, for insofar as Descartes infers that God exists from the fact that existence belongs to His essence, we should also be able to infer that other objects---the fictitious existing lion, say---exist on similar (...) grounds. Descartes's lone defense against this objection is to distinguish true and immutable essences from fictitious ones , a distinction that, in its details, seems to imply a realistic view of essences. Such a view of essences, though, conflicts with Descartes's explicit rejection of Platonism in the Principles of Philosophy , among other places. ;In this dissertation, I offer an interpretation of the Fifth Meditation that resolves this problem by treating true and immutable natures as nothing more than ideas, and I argue that, by a careful reading of several crucial yet rarely noticed texts, we can bring Descartes's cryptic and confusing Fifth Meditation claims under an anti-Platonic rubric. As an upshot of this interpretation, I propose an unusual reading of Descartes's ontological proof, one that draws it much closer to the proof of the Third Meditation and one that, in the end, forces us to reevaluate Descartes's connection to three great figures in the tradition of the ontological proof.
