In this paper I trace the arc of Kant’s critical stance on the belief in God, beginning with the Critique of Pure Reason (1781) and culminating in the final chapter of the Metaphysics of Morals (1797). I argue that toward the end of his life, Kant changed his views on two important topics. First, despite his stinging criticism of it in the Critique of Pure Reason, by the time of the Metaphysics of Morals, Kant seems to endorse the physico-theological argument. (...) Second, some time around the publication of the Metaphysics of Morals, Kant seems to move away from the argument for the practical postulates. (shrink)

Immanuel Kant’s well known and thoroughly discussed criticism of the cosmological argument, hereafter ‘CA’, is that it presupposes or depends upon the cogency of the ontological argument, hereafter ‘OA’. Call this criticism ‘the Dependency Thesis’. It is fair to say that the received view on the matter is that Kant failed to establish the Dependency Thesis.1 In what follows, I argue that the received view is mistaken. I begin by rehearsing the standard objection to what is typically taken to be (...) Kant’s primary argument for the Dependency Thesis. I defend Kant by presenting a different argument for his thesis. This argument is not vulnerable to the standard objection, and there is good reason to think that Kant had such an argument in mind. (shrink)

The essay collection "Kant on Proofs for God's Existence" provides a highly needed, comprehensive analysis of the radical turns of Kant's views on proofs for God's existence.— In the "Theory of Heavens" (1755), Kant intends to harmonize the Newtonian laws of motion with a physico-theological argument for the existence of God. But only a few years later, in the "Ground of Proof" essay (1763), Kant defends an ontological ('possibility' or 'modal') argument on the basis of its logical exactitude while he (...) praises the physico-theological argument for its beauty and appeal to the common sense. In the first "Critique" (1781/7), Kant replaces traditional constitutive ontological, cosmological, and physico-theological proofs with his own regulative theoretical and moral-practical religious arguments. He continues to defend a moral argument in the second "Critique" (1788). But in the third "Critique" (1790), Kant reintroduces a physico-theological besides an ethicotheological argument in order to unify the critical system of philosophy. Kant develops further moral arguments and arguments from evil in the "Theodicy" essay (1791) and the "Religion" (1793/4), and still searches for the right kind of proof for God's existence in the "Opus postumum" (1796–1804).—Part one of this volume is dedicated to an analysis of Kant's proofs for God's existence in their historical order that explains which proofs Kant favors or rejects in various periods of his thought. Part two contains a systematic classification of main kinds of proof for God's existence in Kant that outlines the argumentative structure of particular kinds of proof and discusses Kant's potential reasons for their variations and modifications. The essay collection speaks to Kant specialists, philosophers, and theologians, but introduces the topic to non-academic readers also. -/- Contributers: Uygar Abaci (Pennsylvania State University), Craig Bacon (University of South Carolina), Andrew Chignell (Princeton University), Eckart Förster (Humboldt University, Johns Hopkins University), Ina Goy (Beijing Normal University) Paul Guyer (Brown University), Graham Oppy (Monash University), Lara Ostaric (Temple University), Stephen Palmquist (Independent Scholar), Lawrence Pasternack (Oklahoma State University), Konstantin Pollok (University of Mainz), Oliver Sensen (University of Tulane), Allen Wood (Bloomington University, Stanford University).

A consequence relation \ is monotonic iff for premise sets \ and conclusion \, if \, \, then \; and non-monotonic if this fails in some instance. More plainly, a consequence relation is monotonic when whatever is entailed by a premise set remains entailed by any of its supersets. From the High Middle Ages through the Early Modern period, consequence in theology is assumed to be monotonic. Concomitantly, to the degree the argument formulated by Anselm at Proslogion 2–4 is taken (...) up by later commentators, it is accepted or rejected in accordance with a monotonic notion of consequence. Examining Anselm’s use of parallelism in the Proslogion, I show Anselm embeds his famous argument in Proslogion 2–4 in a non-monotonic context. The results here presented challenge some deeply ingrained ideas governing the historiography of the long twelfth century, particularly concerning how the theology of the later eleventh through the twelfth century relates to the scholasticism of the thirteenth.
