In this absorbing book, renowned psychologist Robert J. Sternberg presents a psychological approach to human relationships that reveals how and why people fall in and out of love. Fascinating reading for anyone who wants to learn more about love, Cupid's Arrow draws on fields ranging from history to cognitive science to folklore, offering a comprehensive account of love in its many forms. Grounded in Sternberg's own 'triangular theory', the book explores the many varieties of love as different combinations of intimacy, passion, and commitment. Using this theory as a focal point, Cupid's Arrow delivers an interesting perspective on the experience of love during the lifetime of the individual as well as a rich history of the conceptions of love throughout the ages.
