Single Idea 21457

[filed under theme 1. Philosophy / E. Nature of Metaphysics / 3. Metaphysical Systems ]

Full Idea

The legislation of human reason (philosophy) has two objects, nature and freedom, and thus contains the natural law as well as the moral law, initially in two separate systems, but ultimately in a single philosophical system.

Gist of Idea

Reason has two separate objects, morality and freedom, and nature, which ultimately unite

Source

Immanuel Kant (Critique of Pure Reason [1781], B868/A840)

Book Ref

Kant,Immanuel: 'Critique of Pure Reason', ed/tr. Guyer,P /Wood,A W [CUO 1998], p.695

A Reaction

Pure reason is for nature, and practical reason (which has priority) is for freedom and morality. There is a streak of religiosity in Kant which makes him give morality and normativity priority over truth and science.
