Summing up: The organic bases of the creative imagination, if there are any specially its own, remain to be determined. For in all that has been said we have been concerned only with some conditions of the general working of the mind--assimilation as well as invention. The eccentricities of inventors studied carefully and in a detailed manner would finally, perhaps, be most instructive material, because it would allow us to penetrate into their inmost individuality. Thus, the physiology of the imagination quickly becomes pathology. I shall not dwell on this, having purposely eliminated the morbid side of our subject. It will, however, be necessary to return thereto, touching upon it in another part of this essay. III There remains a problem, so obscure and enigmatic that I scarcely venture to approach it, in the analogy that most languages--the spontaneous expression of a common thought--establish between physiologic and psychic creation. Is it only a superficial likeness, a hasty judgment, a metaphor, or does it rest on some positive basis? Generally, the various manifestations of mental activity have as their precursor an unconscious form from which they arise. The sensitiveness belonging to living substance, known by the names heliotropism, chemotropism, etc., is like a sketch of sensation and of the reactions following it; organic memory is the basis and the obliterated form of conscious memory. Reflexes introduce voluntary activity; appetitions and hidden tendencies are the forerunners of effective psychology. Instinct, on several sides, is like an unconscious and specific trial of reason. Has the creative power of the human mind also analogous antecedents, a physiological equivalent? One metaphysician, Froschammer, who has elevated the creative imagination to the rank of primary world-principle, asserts this positively. For him there is an objective or cosmic imagination working in nature, producing the innumerable varieties of vegetable and animal forms; transformed into subjective imagination it becomes in the human brain the source of a new form of creation. "The very same principle causes the living forms to appear--a sort of objective image--and the subjective images, a kind of living form."[27] However ingenious and attractive this philosophical theory may be, it is evidently of no positive value for psychology.
