Greek philosophers were among the first to contemplate how the world outside of us is represented inside of us. Henley's HERGENHAHN'S AN INTRODUCTION TO THE HISTORY OF PSYCHOLOGY, 9th Edition, examines the philosophical questions about the influence of nature and nurture -- experience and environment -- and the nature and existence of the human mind and brain. It explains that most of the "big questions" that still concern psychologists today are manifestations of themes that have recurred for hundreds or even thousands of years. Engage with the history of psychology through full-color photographs, learning tools and fascinating biographical material on key figures in psychology.
