Herbart, German philosopher, born at Oldenburg; Kant's successor at Königsberg, professor also at Göttingen twice over; founded his philosophy like Kant on the criticism of subjective experience, but arrived at different results, and arrayed itself against the whole post-Kantian philosophy of Germany; it is described by Schwegler "as an extension of the monadology of Leibnitz, full of ingenuity but devoid of inward fertility, or any germ of movement"; he failed to see, as Dr. Stirling points out, that "Philosophy is possible only on the supposition of a single principle that possesses within itself the capability of transition into all existent variety and varieties" (1776-1841).
