Yes, Sid Fields, one of the characters that well stay with through the pages of this book, is a psychology major. He plans to earn a degree in that subject as perhaps many who are reading this book intend to do. Less than a century ago neither Sid, nor for you for that matter, could have majored in psychology. At that time psychology was not a separate field of study. It was part of philosophy. People who studied psychology were still called philosophers. But what is psychology in our day and age? What do psychologists do? Like most people, Sid isn't quite sure. Sure, he's heard that psychology is 'the study of the mind' whatever that means. The truth is that it doesn't mean much at all.
