This book, or rather the course of lectures on which it is based, is the author's reaction to what he calls the 'serious menace' which the New Psychology holds for religion. By the New Psychology, he understands (1) Behaviourism, and (2) Psycho-analysis 'represented mainly by Freud, Jung, and their disciples'. After Freud and Jung, the most important representatives of this school would appear to be Adler, Tansley, and Beatrice Hinkle. There is fortunately also 'the saner school of psychology', which includes McDougall and Drever, while Dr. William Brown, although practising psycho-analysis, appears to be mostly on the side of the angels.
