The Critique of Practical Reason: By Immanuel Kant (Timeless Classic Books)

In The Critique of Practical Reason, Kant proposes that morality presupposes a thing-in-itself, a moral personality underlying our empirical selves. He believes that it is possible to find absolute moral principles, and the fundamental and most famous of them are: always act so that you treat every individual, yourself included, as an end and never as a means only , and always act as if the principle of your action were to become a universal law of nature . The basic concept of morals for Kant is duty, which is obedience to law for its own sake. He rejects pleasure and happiness as the ends of human life, though he shows their relation to true morality. Belief in God, freedom and immortality, which he showed to be possible in his Critique of Pure Reason , are the presuppositions he considers to be necessary for a moral life.
