A paper which succeeds in being erudite, yet lively, and which tells an amusing tale without digressing from its theme, deserves great admiration. Such is Professor George's discussion of Kant and liberalism. He first points out briefly that in fact Kant exercised small influence on liberal thought in the nineteenth century. The bulk of his paper is devoted to the question of whether Kant was a liberal at all and to justifying his unconventional negative answer. In the course of so doing he presents the diverting tale of the ingenuous young aristocrat who solicits Kant's opinion as to whether one's wife should be inoculated against the pox. But the diversion is pertinent. Kant's two answers to the question reveal two different ways in which the Kantian moral theory, sententiously expressed in the so-called “categorical imperative”, might be incompatible with liberal opinion.
