See Article History Immanuel Kant, (born April 22, 1724, Königsberg, Prussia [now Kaliningrad, Russia]—died February 12, 1804, Königsberg), German philosopher whose comprehensive and systematic work in epistemology (the theory of knowledge), ethics, and aesthetics greatly influenced all subsequent philosophy, especially the various schools of Kantianism and idealism. Top Questions Why is Immanuel Kant important? Immanuel Kant was a German philosopher and one of the foremost thinkers of the Enlightenment. His comprehensive and systematic work in epistemology (the theory of knowledge), ethics, and aesthetics greatly influenced all subsequent philosophy, especially the various schools of Kantianism and idealism. What was Immanuel Kant’s childhood like? Immanuel Kant’s father, a saddler, was, according to Kant, descended from a Scottish immigrant, and his mother was remarkable for her character and natural intelligence. Both parents were devoted Pietists, and the influence of their pastor made it possible for Kant—the fourth of nine children but the eldest surviving child—to obtain an education. What did Immanuel Kant do for a living? Immanuel Kant worked as a family tutor for nine years before he finished university. He worked for 15 years as a Privatdozent, or lecturer, at the University of Königsberg until he was appointed to the chair of logic and metaphysics, a position in which he remained active until a few years before his death. What did Kant write? Kant’s most famous work, the Critique of Pure Reason, was published in 1781 and revised in 1787. It is a treatise which seeks to show the impossibility of one sort of metaphysics and to lay the foundations for another. His other books included the Critique of Practical Reason (1788) and the Critique of Judgment (1790). Kant was one of the foremost thinkers of the Enlightenment and arguably one of the greatest philosophers of all time. In him were subsumed new trends that had begun with the rationalism (stressing reason) of René Descartes and the empiricism (stressing experience) of Francis Bacon. He thus inaugurated a new era in the development of philosophical thought. Background and early years Top Questions: Immanuel KantQuestions and answers about German philosopher Immanuel Kant. Encyclopædia Britannica, Inc.See all videos for this article Kant lived in the remote province where he was born for his entire life. His father, a saddler, was, according to Kant, a descendant of a Scottish immigrant, although scholars have found no basis for this claim; his mother was remarkable for her character and natural intelligence. Both parents were devoted followers of the Pietist branch of the Lutheran church, which taught that religion belongs to the inner life expressed in simplicity and obedience to moral law. The influence of their pastor made it possible for Kant—the fourth of nine children but the eldest surviving child—to obtain an education. At the age of eight Kant entered the Pietist school that his pastor directed. This was a Latin school, and it was presumably during the eight and a half years he was there that Kant acquired his lifelong love for the Latin classics, especially for the naturalistic poet Lucretius. In 1740 he enrolled in the University of Königsberg as a theological student. But, although he attended courses in theology and even preached on a few occasions, he was principally attracted to mathematics and physics. Aided by a young professor who had studied Christian Wolff, a systematizer of rationalist philosophy, and who was also an enthusiast for the science of Sir Isaac Newton, Kant began reading the work of the English physicist and, in 1744, started his first book, Gedanken von der wahren Schätzung der lebendigen Kräfte (1746; Thoughts on the True Estimation of Living Forces), dealing with a problem concerning kinetic forces. Though by that time he had decided to pursue an academic career, the death of his father in 1746 and his failure to obtain the post of under-tutor in one of the schools attached to the university compelled him to withdraw and seek a means of supporting himself.
