Abstract
Mentality and spirituality, the most distinctly human phenomena, have been ignored and forced underground ever since psychology was taken over by materialistic and behavioristic science. This article reviews the contemporary scientific status of mental and spiritual processes in the light of the new worldview of modern physics and other recent developments, including the overthrow of behavior by mentality, the development of humanistic neuroscience, current views concerning the relationship between religion and science, and vigorous work synthesizing religion and psychology. The main conclusion is that views and research in science, philosophy of science, theology, and psychology have converged to support an optimistic outlook for continued integration of mentality and spirituality in psychology.
