THIS evening's talk is the first of a series to be given by Dr. Waterhouse, who is Lecturer in Psychology and the Philosophy of Religion at the Wesleyan College, Richmond. He is also a member of the Senate of London University. Tonight he will discuss the true definition of religion ; the inferences that can be drawn from its most primitive forms ; the question whether religion was one of the original natural instincts of mankind, and the fascinating differences between early religions and the magic-tradition common among all primitive peoples.
