In a series of lectures on German philosophy ‘since Kant’, the names of Fichte, Schelling, and Hegel and their critical reference to Kant are, of course, a must. No less a must, though, would seem to be Wilhelm von Humboldt, a philosopher and linguist who, together with Herder and Hamann, formed the alliterating triumvirate of a romanticist critique of Kant. The response, within the discipline, to transcendental philosophy from this side was, in contrast to the idealistic mainstream, long in the coming but, in the end, rich in consequences.
