But one has a repugnance to descending into this strange region. And religion, with its clear and lofty mood, can never have either taste for or relationship with considerations which so easily take an “occult” turn. Nor is its mysticism concerned with physiologies. But it is instructive and noteworthy that the old idealistic faith, “It is the mind that builds up the body for itself,” is becoming stronger again in all kinds of philosophies and physiologies of “the unconscious,” as a reaction from the onesidedness of the mechanistic theories, and that it draws its chief support from the dependence of nervous and other bodily processes upon the psychical, which is being continually brought into greater and greater prominence. The moderate and luminous views of the younger Fichte, who probably also first introduced the now current term “the unconscious,” must be at least briefly mentioned. According to him, the impulse towards the development of form which is inherent in everything living, and which [pg 353] builds up the organism from the germ to the complete whole, by forcing the chemical and physical processes into particular paths, is identical with the psychical itself. In instincts, the unconscious purposive actions of the lower animals in particular, he sees only a special mode of this at first unconscious psychical nature, which, building up organ after organ, makes use in doing so of all the physical laws and energies, and is at first wholly immersed in purely physiological processes. It is only after the body has been developed, and presents a relatively independent system capable of performing the necessary functions of daily life, that it rises beyond itself and gradually unfolds to conscious psychical life in increasing self-realisation. Edward von Hartmann has attempted to apply this principle of the unconscious as a principle of all cosmic existence. And wherever, among the younger generation of biologists, one has broken away from the fascinations of the mechanistic theory, he has usually turned to “psychical” co-operating factors.
