" Psychological despotism, whether enlightened or not, is gross misuse of psychology. The main purpose of psychology is to acquire insight into, and mastery of, oneself. Not for nothing were what we now call the behavioral sciences originally called the moral sciences and “Know thyself” their main precept. To use psychology to control, dominate, and manipulate others is self-destructive abuse of knowledge. It is also a particularly repugnant form of tyranny. "
