ABSTRACT
As it seems to be the intention of the founder of the Terry Lectures to enable representatives of science, as well as of philosophy and other spheres of human knowledge, to contribute to the discussion of the eternal problem of religion, and since Yale University has bestowed upon me the great honour of delivering the Terry Lectures for 1937, I assume that it will be my task to show what psychology, or rather that special branch of medical psychology which I represent, has to do with or to say about religion. Since religion is incontestably one of the earliest and most universal expressions of the human mind, it is obvious that any psychology which touches upon the psychological structure of human personality cannot avoid taking note of the fact that religion is not only a sociological and historical phenomenon, but also something of considerable personal concern to a great number of individuals.
