An examination of four decades of research and practice in humanistic psychology, this work highlights the lasting contributions of humanistic psychology to the science of psychology and to the pursuit of personal and spiritual development. It explores the passions and goals of the founders and their vital legacy for the 21st century. Humanistic Psychology began as a movement of creative individuals who sought to remake psychology in the image of a fully alive and aware human being. Humanistic psychology emphasizes liberation from personal and social oppression and the pursuit of higher levels of human potential. Humanistic psychologists criticize scientific psychology for their emphasis on the measurement, prediction, and control of behavior, and protest the exclusion of such basic aspects of humanness as consciousness, values, freedom, love, and spirit from psychological investigation. This book will be of interest to undergraduate and graduate students and faculty in psychology as well as professionals in the field.
