In his "Fundamental Principles of the Metaphysics of Morals", Immanuel Kant outlined the structure of moral reasoning, but to reach this critical point in his philosophy he had to demonstrate how reasoning about ethics could emerge. While the "Critique of Pure Reason" offers the foundation for his theories of knowledge and reality and the manner in which we come to possess ideas about the world, Kant's "Critique of Practical Reason" shows how these mental processes are linked how the mind moves from a formal understanding of reasoning in general to moral reasoning in particular.
IMMANUEL KANT, born in K nigsberg, East Prussia (in what is now Kaliningrad, Russia), on April 22, 1724, was reared by parents who were members of the Lutheran sect known as Pietists. Though his upbringing was religious, Kant did not find himself subjected to a dogmatic or doctrinaire home environment. After completing his early education at the Collegium Fridericianum, he entered the University of K nigsberg in 1740 at the age of sixteen. Though it was originally thought that he would make the ministry his life's pursuit, Kant took the minimum number of required courses in theology and then dedicated himself to philosophy, mathematics, and physical science. During the years between 1746 and 1755 he worked as a private tutor in an effort to support himself through graduate work after the death of his parents left him without financial assistance. Receiving his doctorate in 1755, he taught at the University of K nigsberg for fifteen years until 1770 when he was finally promoted to Professor of Logic and Metaphysics. Kant held this position until his death on February 12, 1804. Among Kant's most important philosophical works are: The Critique of Pure Reason (1781), Prolegomena to Any Future Metaphysics (1783), Idea for a Universal History (1784), Fundamental Principles of the Metaphysic of Morals (1785), Metaphysical Foundations of Natural Science (1786), Critique of Practical Reason (1787), Critique of Judgment (1790), Religion within the Limits of Reason Alone (1793), Perpetual Peace (1795), Metaphysics of Ethics (1797), and Anthropology from a Pragmatic Point of View (1798).
