<br/><br/> "Almost everyone agrees that the study of emotion is one of the most confused (and still open) chapters in the history of psychology. By one estimate, more than 90 definitions of 'emotion' were proposed over the course of the 20th century. If there is little consensus on the meaning of the term, it is no wonder that there is much disagreement among contemporary theoreticians concerning the best way to conceptualize emotion and interpret its role in life....How, then, can emotion be studied and understood?" (AMERICAN SCIENTIST) The author proposes a Darwinesque theory of emotion, stressing that emotion is evolutionary.
