Personality is the study of who we are. It’s composed of many theories about how and why we behave as we do. Before we create our own theory of personality, it’s wise to see what others have said on the subject.
The theories are presented in semi-chronological order. But you’ll soon discover that ideas are not limited to one period of time. They pop up, are popular for a while, subside and vanish. But these same ideas will pop up again years, decades or centuries later.
After you’ve read about other views of personality, consider writing your own. It is really helpful to put your thinking into words. And quite challenging. Since I wouldn’t ask you to do something I wouldn’t do myself, I’ve included my theory of personality. Use it as a model of what to include but not necessarily what to believe.
