300th ANNIVERSARY OF THE BIRTH OF IMMANUEL KANT  

What can I know? What must I do? What may I hope? These are the three questions to which Immanuel Kant, a philosopher born in Königsberg, East Prussia in 1724, devoted his life. His answers are contained in the works Critique of Pure Reason (1781 and 1787), Critique of Practical Reason (1788), Critique of the Power of Judgment (1790), and Religion within the Bounds of Bare Reason (1793). Drawing parallels with the intellectual revolution in science led by Copernicus and later Newton, Immanuel Kant fathered a new philosophical movement, which he called critical philosophy. He founded the concept of transcendental idealism, arguing that we intuit the objects of existence according to our own sensibilities, and that we cannot know things in themselves. He also established the notion of absolute worth in morality, which he saw as a categorical requirement for human freedom. Through his teachings and writings, Kant left an indelible mark on philosophy. His ideas were not only taken up, but often adapted by the vast majority of thinkers in the 19^th and 20^th centuries.
