Immanuel Kant

Lore & Background

Immanuel Kant was born into a Lutheran family in Königsberg, East Prussia. He was the fourth of nine children, six of whom reached adulthood. His early education was strict and disciplinary, emphasizing Latin and religious instruction. He enrolled at the University of Königsberg in 1740, studying under Martin Knutzen, who introduced him to Newtonian physics and dissuaded him from pre-established harmony and idealism. After his father's death in 1746, Kant worked as a private tutor before returning to Königsberg in 1754. He published his first philosophical work in 1749 and later obtained a license to lecture in 1755, teaching mathematics, physics, logic, and metaphysics.

Kant's early work included contributions to astronomy, such as the nebular hypothesis and the correct deduction that the Milky Way is a large disk of stars. He also wrote on earthquakes and the theory of winds. In 1770, he was appointed Full Professor of Logic and Metaphysics at the University of Königsberg. His inaugural dissertation introduced key themes of his mature philosophy, including the distinction between intellectual thought and sensible receptivity. Kant never married, though he considered it twice, and was known for his strictly ordered life, with neighbors reportedly setting their watches by his daily walks.

Reader's Guide

Kant's philosophy centers on the human subject and aims to secure knowledge and morality against skepticism and determinism. In the Critique of Pure Reason (1781/1787), he argues for transcendental idealism, holding that space and time are forms of intuition structuring all experience, and that we know only appearances, not things in themselves. He compared this to a Copernican Revolution, proposing that objects conform to the mind's forms and categories. Kant believed reason is the source of morality, expressed through the categorical imperative binding all rational agents. He also held that aesthetics arises from disinterested judgment, and that perpetual peace could be achieved through an international federation of republican states. His religious views, grounded in morality, remain a matter of dispute. Kant's systematic works have made him a central and enduring figure in modern Western philosophy, influencing debates across multiple disciplines.
