This book explores Kant's views on the concept of God and on the attempt to demonstrate God's existence as a means of understanding Kant's work as a whole and of achieving a proper appreciation of the contents of Kant's moral faith.

Kant's sustained reflections on God have received considerable scholarly attention over the years and rightly so. His provocative criticisms of the three traditional theoretical proofs of the existence of God, and his own positive proof for belief in God's existence on moral grounds, have fully deserved the clarification and analysis that has occurred in these discussions. What I want to focus on, however, is the extent to which Kant's position contains resources sufficient to answer a line of questioning about the (...) existence of God that has recently been called the problem of the ‘hiddenness of God’ in contemporary discussions in philosophy of religion. If God exists roughly as the Judeo-Christian philosophical tradition conceives of him, it is puzzling, at least prima facie, why he does not make his existence overwhelmingly obvious to one and all, but rather is hidden from us. For if God is omnipotent, as the tradition maintains, it seems that he would have the power to reveal himself to us and, for that matter, with sufficient clarity that we would be left with no doubt about the matter. And if, as the tradition maintains further, it is important to God that we accept his existence and reject false idols who would pretend to divine status, it would seem that he has a significant reason to reveal himself to us. In short, given that God can make his existence obvious to all, and that doing so would fulfil an important purpose, why does he remain hidden from us? (shrink)

One of the characteristic features of contemporary logic is that it incorporates the Frege‐Russell thesis according to which verbs for being are multiply ambiguous. This thesis was not accepted before the nineteenth century. In Aristotle existence could not serve alone as a predicate term. However, it could be a part of the force of the predicate term, depending on the context. For Kant existence could not even be a part of the force of the predicate term. Hence, after Kant, existence (...) was left homeless. It found a home in the algebra of logic in which the operators corresponding to universal and particular judgments were treated as duals, and universal judgments were taken to be relative to some universe of discourse. Because of the duality, existential quantifier expressions came to express existence. The orphaned notion of existence thus found a new home in the existential quantifier. (shrink)

This book is a unique contribution to the philosophy of religion. It offers a comprehensive discussion of one of the most famous arguments for the existence of God: the ontological argument. The author provides and analyses a critical taxonomy of those versions of the argument that have been advanced in recent philosophical literature, as well as of those historically important versions found in the work of St Anselm, Descartes, Leibniz, Hegel and others. A central thesis of the book is that (...) ontological arguments have no value in the debate between theists and atheists. There is a detailed review of the literature on the topic (separated from the main body of the text) and a very substantial bibliography, making this volume an indispensable resource for philosophers of religion and others interested in religious studies.

Mathematician and philosopher Hermann Weyl had our subject dead to rights.

This is the second edition of an important introduction to Leibniz's philosophy of logic and language first published in 1972. It takes issue with several traditional interpretations of Leibniz (by Russell amongst others) while revealing how Leibniz's thought is related to issues of great interest in current logical theory. For this new edition, the author has added new chapters on infinitesimals and conditionals as well as taking account of reviews of the first edition.

In the transcendental aesthetic of the Critique of Pure Reason, Kant claims that space and time are neither things in themselves nor properties of things in themselves but mere subjective forms of our sensible experience. Call this the Subjectivity Thesis. The striking conclusion follows an analysis of the representations of space and time. Kant argues that the two representations function as a priori conditions of experience, and are singular "intuitions" rather than general concepts. He also contends that the representations underwrite (...) some non-trivial a priori cognition of the objects of sensible experience. The Subjectivity Thesis is then presented as an immediate consequence: Space represents no property at all of any things in themselves nor any relation of them to each other. . . . For neither absolute nor relative determinations can be intuited prior to the existence of the things to which they pertain, thus [neither] can be intuited a priori. Time is not something which exists of itself, or which inheres in things as an objective determination. . . . [Were it] a determination or order inhering in things themselves, it could not precede the objects as their condition, and be known and intuited a priori by means of synthetic propositions. Kant's argument for the Subjectivity Thesis seems to have the following structure: * No absolute or relational features of things in themselves can be cognized a priori. (shrink)

Kant's speculative theistic proof rests on a distinction between “logical” and “real” modality that he developed very early in the pre-critical period. The only way to explain facts about real possibility, according to Kant, is to appeal to the properties of a unique, necessary, and “most real” being. Here I reconstruct the proof in its historical context, focusing on the role played by the theory of modality both in motivating the argument (in the pre-critical period) and, ultimately, in undoing it (...) as a source of knowledge of God's existence (in the critical period). Along the way I examine Kant's version of the now-popular “actualist” thesis that facts about what is possible must be explained by facts about what is actual. I conclude by discussing why the critical Kant claims both that there are rational grounds for accepting the conclusion of his theistic proof, and that such acceptance can not count as knowledge. This is important, I argue, because the same considerations ultimately motivate his prohibition on knowledge of things-in-themselves generally. -/- . (shrink)

Legendary since his own time as a universal genius, Gottfried Wilhelm Leibniz (1646-1716) contributed significantly to almost every branch of learning. One of the creators of modern mathematics, and probably the most sophisticated logician between the Middle Ages and Frege, as well as a pioneer of ecumenical theology, he also wrote extensively on such diverse subjects as history, geology, and physics. But the part of his work that is most studied today is probably his writings in metaphysics, which have been (...) the focus of particularly lively philosophical discussion in the last twenty years or so. The writings contain one of the great classic systems of modern philosophy, but the system must be pieced together from a vast and miscellaneous array of manuscripts, letters, articles, and books, in a way that makes especially strenuous demands on scholarship. This book presents an in-depth interpretation of three important parts of Leibniz's metaphysics, thoroughly grounded in the texts as well as in philosophical analysis and critique. The three areas discussed are the metaphysical part of Leibniz's philosophy of logic, his essentially theological treatment of the central issues of ontology, and his theory of substance (the famous theory of monads).

In one of his precritical works, Kant defends, as “the only possible” way of demonstrating the existence of God, an argument from the nature of possibility. Whereas Leibniz had argued that possibilities must be thought by God in order to obtain the ontological standing that they need, Kant argued that at least the most fundamental possibilities must be exemplified in God. Here Kant’s argument is critically examined in comparison with its Leibnizian predecessor, and it is suggested that an argument combining (...) the strengths of both of them has much to be said for it.

Volumes I and II provided a completely new translation of the philosophical works of Descartes, based on the best available Latin and French texts. Volume III contains 207 of Descartes' letters, over half of which have previously not been translated into English. It incorporates, in its entirety, Anthony Kenny's celebrated translation of selected philosophical letters, first published in 1970. In conjunction with Volumes I and II it is designed to meet the widespread demand for a comprehensive, authoritative and accurate edition (...) of Descartes' philosophical writings in clear and readable modern English.

This book offers a critical account of the fundamental elements of Leibniz's philosophy, as they manifest themselves in his metaphysics and philosophy of language. Emphasis is placed upon his hitherto neglected doctrine of nominalism, which states that only concrete individuals exist and that there are no such things as abstract entities – no numbers, geometrical figures or other mathematical objects, nor any abstractions such as space, time, heat, light, justice, goodness, or beauty. Using this doctrine as a basis, the book (...) considers the core of Leibniz's metaphysics and philosophy of language, including the well‐known principles of Contradiction, Sufficient Reason, Continuity and Individuation, and the concepts of Possible World, Individual Substance, Truth, and Necessity.

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.
