I seem to be, to my surprise, a member of a large profession. There are some 20,000 psychologists in this country alone, nearly all of whom have become so in my adult lifetime. They are all prosperous. Most of them seem to be busily applying psychology to problems of life and personality. They seem to feel, many of them, that all we need to do is to consolidate our scientific gains. Their self-confidence astonishes me. For these gains seem to me puny, and scientific psychology seems to me ill-founded. At any time the whole psychological applecart might be upset. Let them beware
