Waylan F. Vaughn. The psychology of Alfred Adler is taken as the basis for our study of normal personality. Analysis of the self-regarding sentiment indicates that the person with marked deficiencies is peculiarly susceptible to the will-to-power, by reason of the various kinds of inferiority that trouble [one]. Compensation will be worked out in detail to demonstrate how the accomplishment of certain purposes is rendered possible. The consciousness of inferiority arouses the mighty forces of the instinctive and emotional life and sets the conditions that favor the attainment of distinction in art, religion, learning, and other paths to power. The application of the theory to various social groups will be illustrated by an analysis of the motivation behind [various movements]. Studies of Arthur Schopenhauer and Abraham Lincoln will give an insight into the way the individual works out his compensation.
