THE PRIMITIVE EMOTIONS IN RELATION TO THE FAMILY
[Sidenote: Psycho-analysis and the study of the Unconscious]
The progress that has recently been made in our understanding of the importance and nature of the psychological problems connected with family life is to a very considerable extent due to the work of a single school of psychologists--the so-called psycho-analytic school, which owes its origin to Prof. Sigmund Freud of Vienna. The success that has attended the efforts of this school has arisen principally from the fact that the psycho-analysts have not confined their researches to the conscious contents of the mind directly discoverable by introspection, but have sought also to investigate the subconscious or unconscious factors which enter into human conduct and mentation[3].
To assume the existence of unconscious mental processes has seemed to some to involve an open contradiction in terms; but at the present day there are few if any psychologists who think that a satisfactory science of the mind can be erected on the basis of the study of consciousness only. Even before Psychology had definitely acquired the status of an independent science, thinkers like Leibnitz, Schopenhauer, Fechner, Helmholtz, Hartmann, Nietzsche, had realised that a complete account of the nature and origin of the phenomena of consciousness required the postulation of some force outside consciousness, or at any rate outside the main stream of consciousness, which yet appeared to react upon and co-operate with consciousness, and which could be interpreted and understood in terms of conscious process.
This result of more or less _a priori_ speculation subsequently received striking _a posteriori_ confirmation from the work of a large number of those engaged in different branches of psychological investigation; including psycho-pathologists like Charcot, Janet, Morton Prince, students of Psychical Research like F. W. H. Myers, Gurney, Hodgson and experimental psychologists like Müller and Schumann, Knight-Dunlap and Ach. The extensive data contributed from these sources seemed to afford convincing proof that processes such as we are ordinarily inclined to regard as being invariably accompanied by consciousness, can occur, at any rate under certain circumstances, without the knowledge or conscious co-operation of the person by whom they are accomplished. The penetrating insight, the fearless logical consistency, combined with the exceptional ability of detecting widespread but hidden identities and similarities which have distinguished the work of Freud enabled him to show that, far from being operative only under certain special or rare conditions, the unconscious mental forces of the human mind are continually active during waking life and even during sleep, and exercise a profound influence on the whole course of consciousness and conduct. As the result of the far reaching investigations of Freud and of his followers, it would seem indeed that we shall probably have to look to the Unconscious for an understanding of the ultimate nature of all the deepest and most powerful motive forces of the mind.
