Biography

Immanuel Kant (kahnt), perhaps the most influential philosopher in the Western world since Aristotle, was born in 1724 in the East Prussian city of Königsberg, which remained his lifelong home. After graduating from the university there in 1746 he was a tutor for about nine years. In 1755 he began to teach at the university. He never traveled far from the city, nor, from 1755 on, did his interest extend beyond the precincts of his academic retreat. The external events of his life were consequently few and limited in their physical scope. The course of his existence was inward, the action that he was involved in taking place in the abstract fields of logic and illuminated by the nondiurnal light of reason.

Immanuel Kant

(Library of Congress)

Kant’s first enterprises were scientific and mathematical, resulting in a theory of the nebular origin of the solar system that anticipated the hypothesis later developed by the astronomer Pierre-Simon de Laplace. His natural bent, however, inclined him toward work in pure philosophy, and it was in that realm that his greatest accomplishments were made. He began as an adherent of the rationalist school of Gottfried Wilhelm Leibniz and Christian Freiherr von Wolff, but by 1763 he had reversed his position and come under the influence of David Hume after his writings became known in Germany. Unable to synthesize from the works of his predecessors a metaphysics he thought suitable, Kant set out to construct a system of his own; it was his hope to develop a metaphysics that would establish a basis of truth for the discoveries of science and at the same time allow for a belief in God and immortality. To do this Kant discovered that he would first have to examine the cognitive faculties of human beings, which was the impetus for his Critique of Pure Reason, which he began in 1770 as a preparatory study for a new system of metaphysics. By the time he had completed the work eleven years later, there was no need for a further metaphysical study, for the Critique of Pure Reason was a metaphysics in itself and in it Kant had, at least to his own satisfaction, achieved his two ends: He had demonstrated a system that asserts human beings’ a priori knowledge in matters pertaining to science yet, at the same time, removes all matters of God and immortality from the sphere of scientific reasoning, placing them in the realm of faith.

Kant went on to extend these principles in two of his later works, but although he had demonstrated his theories to his own satisfaction, he had not done so to the satisfaction of all those who came after him. Since its first appearance, his Critique of Pure Reason has been subjected to the severest criticism. Nevertheless, the work’s influence, particularly on the writers and poets of the Romantic era, has been tremendous, and any approach to the study of philosophy must deal with Kant’s assertions in one way or another. In particular it is Kant’s “Copernican Revolution” in philosophy, which locates the source of knowledge in the perceiver and not in the thing perceived, that has been highly influential.
