Before leaving this idealistic movement in Germany, and elsewhere as influenced largely by German philosophy, one other name deserves mention. This name is that of Lotze, who combined elements from many previous thinkers with those derived from his own studies and thoughts,--the conceptions of mechanism as applied to physical existences and to psychical life, with the search for some monistic Principle that shall satisfy the æsthetical and ethical, as well as the scientific demands of the human mind. This variety of interests and of culture led to the result of his making important contributions to psychology, logic, metaphysics, and æsthetics. If we find his system of thinking--as I think we must--lacking in certain important elements of consistency and obscured in places by doubts as to his real meaning, this does not prevent us from assigning to Lotze a position which, for versatility of interests, genial quality of reflection and criticism, suggestiveness of thought and charm of style, is second to no other in the history of nineteenth century philosophical development. In France and in England the first quarter of the last century was far from being productive of great thinkers or great thoughts in the sphere of philosophy. De Biran (1766-1824), in several important respects the forerunner of modern psychology, after revolting from his earlier complacent acceptance of the vagaries of Condillac and Cabanis, made the discovery that the "immediate consciousness of self-activity is the primitive and fundamental principle of human cognition." Meantime it was only a little group of Academicians who were being introduced, in a somewhat superficial way, to the thoughts of the Scottish and the German idealistic Schools by Royer-Collard, Jouffroy, Cousin, and others. A more independent and characteristic movement was that inaugurated by Auguste Comte (1798-1857), who, having felt the marked influence of Saint-Simon when he was only a boy of twenty, in a letter to his friend Valat, in the year 1824, declares: "I shall devote my whole life and all my powers to the founding of positive philosophy." In spite of the impossibility of harmonizing with this point of view the vague and mystical elements which characterize the later thought of Comte, or with its carrying into effect the not altogether intelligent recognition of the synthetic activity of the mind (_tout se réduit toujours à lier_) and certain hints as to "first principles;" and in spite of the small positive contribution to philosophy which Comtism could claim to have made; it has in a way represented the value of two ideas. These are (1) the necessity for philosophy of studying the actual historical forces which have been at work and which are displayed in the facts of history; and (2) the determination not to go by mere unsupported speculation beyond experience in order to discover knowable Reality. There is, however, a kind of subtle irony in the fact that the word "Positivism"
