In this chapter, I will offer a first and preliminary outline of Kant's accounts of reason and metaphysics and introduce various themes that will be developed further in later chapters. 1
Kant's Conception of ReasonReason, for Kant, is primarily a mental capacity, or 'faculty of the soul' (Seelenvermögen) (5:177)that is, an ability of thinking beings to be in mental states of different kinds. 2 More specifically, reason is a cognitive faculty (Erkenntnisvermögen) that allows one to have 'objective representations': mental states aimed either at truly representing things or at actively bringing things about (in the widest possible sense of 'things'). Human beings have various cognitive capacities, distinguished by the kinds of representations to which they give rise (or, more generally, by the cognitive functions they perform): sensibility, understanding, imagination, power of judgment, reason (and more). Kant has different ways of classifying these capacities depending on which of their features he is interested in. 3 With respect to reason, Kant employs two such classifications: on the one hand, cognitive capacities can be classified as resulting either in a priori or in empirical cognition (e.g. A835-6/ B863-4); on the other hand, they can be distinguished according to whether they represent things intuitively (in human beings this is the case with sensible From Reason to Metaphysics
