Originally published in 1929, McDougall examines the pertinent conflict between religion and science. His work exhibits the failure of scientists to explain human action mechanistically (the essence of modern materialism), establishes purposive action as a type of event radically different from all mechanistic events, and justifies the belief in teleological causation without which there can be neither religion nor morals. This title will be of interest to students of both the Humanities and Sciences, particularly those studying psychology and philosophy.
