Philosophical and Psychological Usages of the Terms Mind, Consciousness, and Soul

The term soul has generally been applied to the supposed spiritual essence of human personality which persists after death. As such it is connected with problems not soluble by ordinary empirical methods. Psychology as an empirical natural science has consequently ceased to use it as a familiar part of its terminology.

The term mind as meaning a durable psychic entity has also come to enjoy a highly precarious position. William James' defense [p. 47] of the 'Thought of the Moment' as the only thinker needed in psychology is the classic expression of the passing of the old-fashioned conception of the mind. Mind as a term applicable to the entirety of mental phenomena, but not to a stable entity, continues to serve a useful function.

If concrete psychological events could be explained more effectively than otherwise by the hypothesis of a soul or a permanent mind; no doubt these terms and their corresponding concepts would still be actively represented in our literature. But this is not generally thought to be the case.

Signs are not wanting that the term consciousness itself is likewise in dange[sic] of extinction or at least essential modification. As a class name valuable for designating a group of phenomena presenting peculiar problems, it will presumably long remain with us. This will no doubt prove true despite the difficulty of defining it and despite the efforts of certain metaphysicians to reduce consciousness to one among other relations sustained to one another by objects. But there is unquestionably a widespread movement on foot in which interest is centered in the results of conscious process, rather than in the processes themselves. This is peculiarly true in animal psychology; it is only less true in human psychology. In these cases interest is in what may for lack of a better term be called 'behavior'; and the analysis of consciousness is primarily justified by the light it throws on behavior, rather than vice versa.

If this movement should go forward, we should probably have a general science of behavior, recognizing two main sub-divisions, physiological and psychical.

In any event this is a period in which sharp distinctions of one science from another are commonly regarded as both impracticable and unprofitable. With the movement in psychology over toward biological and physiological conceptions, it may reasonably be expected that the word consciousness will take on more marked dynamic and functional characteristics, so that even if the term persists, it will undergo material alteration in its implications.
