Man is a machine which reacts blindly to external forces and, this being so, he has no will, and very little control of himself, if any at all. What we have to study, therefore, is not psychology-for that applies only to a developed man-but mechanics. Man is not only a machine but a machine which works very much below the standard it would be capable of maintaining if it were working properly.
