Transformations of the Concept of Reason

Abstract

This outline of the transformations of the concept of reason is based on the idea that this can be presented/illustrated by means of a historical sketch of the criticism of reason, because all essential differentiations in that concept can be understood as consequences of critical arguments. In Kant's work, the Critique of Speculative Reason reaches its first conclusion; it was followed by a Critique of Critical Reason by Hegel and his followers, and Schopenhauer established a new type of critical argument: the Critique of Functional Reason which dominates the radical criticism of reason in our time. This radical criticism is the great challenge for the philosophy of reason today.
