Abstract

Psychology is the science of the mind. It aims to find out all about the mind--the whole story--just as the other sciences aim to find out all about the subjects of which they treat--astronomy, of the stars; geology, of the earth; physiology, of the body. And when we wish to trace out the story of the mind, as psychology has done it, we find that there are certain general truths with which we should first acquaint ourselves; truths which the science has been a very long time finding out, but which we can now realize without a great deal of explanation.
