Who Would Not Treat a Person as a Means · Philosopher · 1724 – 1804

Who was Kant?
Kant was born at Königsberg in East Prussia in 1724, the fourth child of a harness-maker, and brought up in a strict Pietist household. He never left the region in his life. He worked as a private tutor for nine years before returning to the university, lectured for fifteen years as an unsalaried instructor paid by the students who attended, and only became professor of logic and metaphysics in 1770 at the age of forty-six. For eleven years after that he published almost nothing, and then produced the Critique of Pure Reason in 1781, at fifty-seven, followed by the Groundwork of the Metaphysics of Morals in 1785, the Critique of Practical Reason in 1788 and the Critique of Judgement in 1790. His moral philosophy rests on a single idea: that a rational being has dignity rather than price, and may never be treated merely as a means to somebody else's end. From this he derives the categorical imperative and a series of conclusions, some of which his admirers find difficult. He held that punishment may never be inflicted merely to produce a good result, because that uses the criminal as an instrument, and that it must therefore be inflicted because a crime was committed and in proportion to it. In the Metaphysics of Morals of 1797 he attacked Cesare Beccaria by name for arguing against capital punishment, and gave the island example: if a civil society dissolved itself by agreement, the last murderer in prison ought first to be executed, so that everyone should understand what their deeds deserve. He wrote Religion within the Boundaries of Mere Reason in 1793 and was ordered by Friedrich Wilhelm II to stop publishing on religion; he complied while the king lived and resumed when he died. He was famously regular in his habits, never married, and died at Königsberg in 1804.
