That the unity of the Self as an intelligent and moral being, that the Ego of self-consciousness was an ideal and a product of development, was what Herbart soon became convinced of. The unity of Self is even as given in mature experience an imperfect fact. It is a fact, that is, which does not come up to what it promised, and which requires to be supplemented, or philosophically justified. Here and everywhere the custom of life carries us over gaps which yawn deep to the eye of philosophic reflection: even though accident and illness force them not unfrequently even upon the blindest. To trace the process of unification towards this unity—to trace, if you like, even the formation of the concept of such unity, as a governing and guiding principle in life and conduct, comes to be the problem of the psychologist, in the largest sense of that problem. From Soul (_Seele_) to Mind or Spirit (_Geist_) is for Herbart, as for Hegel, the course of psychology(27). The growth and development of mind, the formation of a self, the realisation of a personality, is for both the theme which psychology has to expound. And Herbart, not less than Hegel, had to bear the censure that such a conception of mental reality as a growth would destroy personality(28). But with so much common in the general plan, the two thinkers differ profoundly in their special mode of carrying out the task. Or, rather, they turn their strength on different departments of the whole. Herbart’s great practical interest had been the theory of education: “paedagogic” is the subject of his first important writings. The inner history of ideas—the processes which are based on the interaction of elements in the individual soul—are what he specially traces. Hegel’s interests, on the contrary, are more towards the greater process, the unities of historical life, and the correlations of the powers of art, religion, and philosophy that work therein. He turns to the macrocosm, almost as naturally as Herbart does to the microcosm. Thus, even in Ethics, while Herbart gives a delicate analysis of the distinct aspects or elements in the Ethical idea,—the diverse headings under which the disinterested spectator within the breast measures with purely aesthetic eye his approach to unity and strength of purpose, Hegel seems to hurry away from the field of moral sense or conscience to throw himself on the social and political organisation of the moral life. The General Paedagogic of Herbart has its pendant in Hegel’s Philosophy of Law and of History.
