Abstract

In this article I show that Kant’s Critique of Pure Reason has as its principal aim to demonstrate that the age-old interests of reason in metaphysics are satisfied not through theoretical knowledge but through a practically-oriented system of reason based on critical principles. The central idea of the system is the highest good in the world conceived as a project to be realized by the human species in the course of history. The dogmatic efforts to attain knowledge of the unconditioned in its three forms as the ideas of the soul, the world and God, are replaced by the critical efforts to realize the highest good as supported by postulates of freedom, immortality and a supreme being required by morality. The concluding chapters of the Critique, mostly ignored by commentators, elaborate on the telos of the critical project. They show that Kant regards critical philosophy as bringing to completion the era of speculative philosophy that began in Greek antiquity and beginning a new epoch of practically-oriented reason that truly satisfies the metaphysical interests of reason
