One of Dion Fortune's first works - when she still wrote under her given name, Violet Firth - this book began life as a series of lectures on elementary psychology given at the Medico-Psychological Clinic in Brunswick Square, London, where she was a counsellor from 1914-1916. Prior to her employment there, Fortune had studied psychology and psychoanalysis at London University.

The text covers the major aspects of the life of the mind: consciousness, instincts, repression, symbolization, fantasies, dreams and hypnosis.

An invaluable introduction to Dion Fortune's foundational views on psychology, which does much to illuminate her later, more celebrated work in occult and esoteric circles.
