Ekman leverages his research on facial expressions to explore human emotion in Emotions Revealed: Recognizing Faces and Feelings to Improve Communication and Emotional Life. At the most basic level, the book serves as a guide to perceiving and understanding emotions in oneself and others. More thought-provoking, though, are Ekman’s insights into emotion as a driver of behavior and his conjectures as to the evolutionary bases for emotion. For the motivated reader, references to academic research are provided.
