“This is a remarkably rich book. I only wish that while studying philosophy in graduate school and in the years that followed I had the guidance and sophisticated learning that Professor King provides. With his assistance my understanding would have been much deeper and more comprehensive.” —Ewert Cousins, Fordham University, General Editor of World Spirituality: An Encyclopedic History of the Religious Quest “In bringing Jung’s typology to bear on the work of some of the most influential philosophers in the Western tradition, Professor King has accomplished a mighty task. In his own words, he demonstrates how philosophy ‘includes the soul of the philosopher’ and how it ‘involves the quest of the soul for salvation.’ To show how the religious impulse and the philosophical search for truth are interwoven in the lives of these men, as he does here so insightfully, is a prodigious accomplishment. Students of both philosophy and the psychology of Jung should be illuminated by this book.” —Cornelia Dimmitt, Jungian analyst “King has the interesting idea of applying Jung’s typology to the study of some philosophers. . . . He shows Locke to be so predominantly a Sensation type that he found difficulty in seeing any relation between discrete particulars, or allowing general ideas into his philosophical scheme. This is a fruitful and novel exploration of the ways philosophers think.” —Anthony Storr, FRCPPsych., Oxford, author of C. G. Jung. editor of The Essential Jung.
