The Critique of Practical Reason (German: Kritik der praktischen Vernunft) is the second of Immanuel Kant's three critiques, first published in 1788. It follows on from Kant's Critique of Pure Reason and deals with his moral philosophy.
The second Critique exercised a decisive influence over the subsequent development of the field of ethics and moral philosophy, beginning with Fichte's Doctrine of Science and becoming, during the 20th century, the principal reference point for deontological moral philosophy.
Famous quotes containing the word practical:
“Missionaries, whether of philosophy or religion, rarely make rapid way, unless their preachings fall in with the prepossessions of the multitude of shallow thinkers, or can be made to serve as a stalking-horse for the promotion of the practical aims of the still larger multitude, who do not profess to think much, but are quite certain they want a great deal.”
—Thomas Henry Huxley (182595)
