Abstract

It is commonly assumed that Kant is indebted to Aristotle not to Plato. In this paper we argue, however, that the following four central topics in Kant's philosophy must be recognized as having Platonic roots. 1. The idea that metaphysics is a system of synthetic apriori judgements and the idea that such judgments require pure intuition. 2. The idea that geometrical objects have a certain purposiveness. 3. The notion of dialectic. 4. The notion of ideas and their role in the sphere of cognition and morality.
