This sequel to The Road Less Traveled, composed from lectures that best-selling author and psychiatrist Peck has given since his last success, presents spiritual as well as psychological aspects of adult maturation. He explores growing up into forgiveness rather than blame; finding meaning in death; developing genuine self-esteem while dealing with problems of omnipotence, good and evil, and heroism; coping with addictions, which Peck terms the sacred disease; and finding a personal god. Peck criticizes psychiatry for ignoring the spiritual histories of patients and for misdiagnosing as a result.
