The problem of highness-lowness and schematism in Kantian philosophy

This thesis deals with the act that Kant calls schematism, the way of applying intellectual concepts to sensible appearances. Schematism has been generally criticized or deemed incomprehensible by thinkers, but it constitutes a vitally important aspect of the critical philosophy. In this study, I will attempt to show how schematism provides transitions between representations and establishes the relation between sensibility and understanding, also between understanding and reason. The relation is about how the understanding constructs the material of sensibility, and how the reason regulates the cognitions of the understanding. In this respect, I will also show that possible transitions between representations (discursive, determinative, reflexive and analogical) enable different ways of schematism. It will be shown that schematism grounds mathematics, and physiology (physics and metaphysics) based on temporality.
