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" should have come to stand so largely for _negative_ conclusions, in the very spheres of philosophy, morals, and religion where _affirmative_ conclusions are so much desired and sought.
That philosophy in Great Britain was in a nearly complete condition of decadence during the first half or three quarters of the nineteenth century was the combined testimony of writers from such different points of view as Carlyle, Sir William Hamilton, and John Stuart Mill. And yet these very names are also witnesses to the fact that this decadence was not quite complete. In the first quarter of the century Coleridge, although he had failed, on account of weakness both of mind and of character, in his attempt to reconcile religion to the thought of his own age, on the basis of the Kantian distinction between reason and the intellect, had sowed certain seed-thoughts which became fertile in the soil of minds more vigorous, logical, and practical than his own. This was, perhaps, especially true in America, where inquirers after truth were seeking for something more satisfactory than the French skepticism of the revolutionary and following period. Carlyle's mocking sarcasm was also not without wholesome effect.
