One of the central debates in contemporary Kant scholarship concerns whether Kant endorses a “conceptualist” account of the nature of sensory experience. Understanding the debate is crucial for getting a full grasp of Kant's theory of mind, cognition, perception, and epistemology. This paper situates the debate in the context of Kant's broader theory of cognition and surveys some of the major arguments for conceptualist and non-conceptualist interpretations of his critical philosophy.

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)

One of Kant’s categories—a priori concepts the possession and applicability of which are necessary conditions of possible experience—is a concept of necessity. But it is unclear why the concept of necessity, as Kant defines it, should be a category thus understood. My aim is to offer a reading of Kant that fills this lacuna: the category of necessity is required to make necessity as it features in the world of experience understandable: a concept that the understanding can grasp and employ (...) in cognition of objects. Kant’s view has potential wider significance for accounts of the function of necessity judgments. (shrink)

Kant makes a striking reference to Spinoza in the 1788 Critique of Practical Reason. This chapter begins by investigating whether Kant directly concerned himself with Spinoza, focusing on Omri Boehm's recent affirmative argument. Kant thinks the objective principle yields radical metaphysical conclusions only in conjunction with further claims about specific conditioning relations. Kant's privileging of Spinozism among realist views seems generally detached from Spinoza's actual thought. The chapter deals with points of convergence or near‐convergence between Kant and Spinoza. It identifies (...) two philosophically interesting points on which Spinoza's and Kant's views come surprisingly close: their arguments for the limitations of our sensory knowledge and their arguments for the timelessness of the mind. Spinoza's official argument for the timelessness of the mind appeals to his doctrines of the body's eternal essence, the parallel between bodies and ideas, and the identity of the human mind with God's idea of the human body.
