This chapter discusses Kant's 1763 "possibility proof" for the existence of God. I first provide a reconstruction of the proof in its two stages, and then revisit my earlier argument according to which the being the proof delivers threatens to be a Spinozistic-panentheistic God—a being whose properties include the entire spatio-temporal universe—rather than the traditional, ontologically distinct God of biblical monotheism. I go on to evaluate some recent alternative readings that have sought to avoid this result by arguing that the (...) relevant facts about real modality can be ultimately grounded in God’s powers or thoughts – or that Kant just leaves the grounding relations mysterious. I argue that the textual and philosophical costs of each of these alternative readings are formidable. The chapter concludes with a discussion of the fate of the proof in the critical period. Some commentators think that it disappears altogether, or that it is downgraded such that it produces a mere regulative idea of God as the most real being. I suggest that the proof survives but that the mode of assent it licenses towards its conclusion changes from knowledge to a certain kind of Belief (Glaube). (shrink)

Kant’s postulate of possibility states that possible is whatever agrees with the formal conditions of experience. As has often been noted, this is a definition of real possibility. However, little attention has been paid to the relation of Kantian real possibility to the German philosophical tradition before him. I discuss three kinds of possibility present in this tradition – internal, external, and (Crusian) real possibility – and argue that Kant endorses internal and external possibility. Furthermore, I show, specifically with respect (...) to the concept of state (Zustand), that the three traditional conceptions are reminiscent of three conceptions of real possibility that Kant implicitly distinguishes. Lastly, I argue that, according to Kant, we need experience to prove real possibility (at least as regards the three conceptions of the real possibility of states) because otherwise we could not know whether the formal conditions of experience obtain.

Andrew Chignell and Omri Boehm have recently argued that Kant’s pre-Critical proof for the existence of God entails a Spinozistic conception of God and hence substance monism. The basis for this reading is the assumption common in the literature that God grounds possibilities by exemplifying them. In this article I take issue with this assumption and argue for an alternative Leibnizian reading, according to which possibilities are grounded in essences united in God’s mind (later also described as Platonic ideas intuited (...) by God). I show that this view about the distinction between God’s cognition of essences as the ground of possibility and the actual world is not only explicitly stated by Kant, but is also consistent with his metaphysical picture of teleology in nature and causality during the pre-Critical period. Finally, I suggest that the distinction between the conceptual order of essences embodied in the idea of God and the order of the objects of experience plays a role in the transition into the Critical system, where it is transformed into the distinction between the intelligible and the sensible worlds.

This paper provides a novel reconstruction of Kant’s argument for transcendental idealism in the Transcendental Aesthetic. This reconstruction relies on two main contentions: first, that Kant accepts the then-ubiquitous view that all cognition is either from grounds or consequences, a view he props up by drawing a distinction between logical and real grounds; second, that Kant, like most of his contemporaries, holds that our representations are the most immediate grounds of our cognition. By stressing these elements, the most threatening objection (...) to Kant’s argument can be avoided, namely, the claim that Kant ignores the possibility that our representations of space and time are subjective in origin, but objective as regards their applicability. My reconstruction shows that this so-called neglected alternative objection is based on a conceptual confusion about the nature of a priori cognition. (shrink)

This thesis was on how God is related to the truth-values of propositions on possible worlds - specifically, those propositions that do not seem to be about Him and constitute His ideas for what to create. It opened with a survey of some historical positions with special emphasis on Aquinas, Leibniz, Spinoza and Kant. Next, some criticisms were given for these so-called deity theories with the most space given to Brian Leftow’s critiques. The second chapter detailed Brian Leftow’s theological modality. (...) In it, secular modality is excogitated in an instant from eternity when God gets a set of creaturely natures in one imaginative act. His preferences that are based on His nature then determine the modality of what God thinks up. A number of objections were raised for the Leftowian project and the last chapter attempted to supplement an older deity theory with some insights from Leftow in order to avoid his initial criticisms.
