Dr. Paul E. Johnson, of Boston University, has long been widely and favorably known as an authority in the subject matter of this book, the psychology of religion. This he describes as a development of general psychology reaching in the direction of religious behavior to comprehend its meaning. Thus he examines psychologically such aspects of religious behavior as religious experience, conversion, prayer and worship, belief, religion and health, vocation and community. He has done this before in an earlier edition of this book, but the insights of the science of psychology have widened and deepened so rapidly in recent years that a revision and enlargement of his earlier basic book, so useful for many years, was demanded. In bringing his book up-to-date, Dr. Johnson shows that he is still a master in this field, not only keeping abreast of recent developments but also making important contributions of his own. Students of religion, lay and clerical, must make themselves familiar with this book.
