PSYCHOLOGY treats directly of Cognition, Feeling, and Volition, and indirectly of Intellect, Sensibility, and Will. Greater prominence is thus given to the phenomena of the soul, with their conditions and laws, than to the faculties implied by these phenomena. Though much light has, no doubt, been thrown upon Psychology by the investigations of Physiologists,—light which the Psychologist should heartily welcome,—yet to know any phenomenon, as it is in itself, we must study it as revealed in consciousness. This is especially true of the higher processes of thought. Thus, to understand the nature of the reasoning process, it will not suffice to examine the structure and functions of the nerves, the ganglia, the brain, and the organs of sense, but we must analyze the reasoning process itself as a known fact of conscious experience. The discussion of the Intuitions is introduced at an early stage, since they afford the fundamental principles for subsequent investigations. To defer the consideration of fundamental principles to the last pages, as is commonly done, would embarass all preceding discussions. What would be thought of a writer on Geometry, who should put his axioms on the last page of his book? The difficulty of discussing fundamental principles is no justification for such an arrangement, since any mind. mature enough to undertake the study of Psychology, is certainly prepared to understand a clear presentation of its first principles. |
