The Main Problem.

The subject to be treated by me on this occasion may perhaps seem to some people almost presumptuous. For psychology is not without severe critics. I can hear one of these saying that, before it takes upon itself to teach others, it would do well to put its own house in order. Is it not, by general admission, passing through a “crisis”? Have not half-a-dozen theories arisen, each of which claims to be the “new” psychology, whereby all the older views are now to be finally superseded?
