Kant has adopted in this work the method which he thinks most suitable, proceeding analytically from common knowledge to the determination of its ultimate principle, and again descending synthetically from the examination of this principle and its sources to the common knowledge in which we find it employed. The division will, therefore, be as follows: First Section. Transition from the common rational knowledge of morality to the philosophical. Second Section. Transition from popular moral philosophy to the metaphysic of morals. Third Section. Final step from the metaphysic of morals to the critique of the pure practical reason.
