The Energies of Men (Psychology Revivals)
First published in 1932, the original blurb states: "This is a simplified condensation of the author’s two volumes, An Outline of Psychology and An Outline of Abnormal Psychology, which together give a comprehensive survey of the principles and findings of modern psychology.

It concentrates on the dynamics of the human organism and aims to give the student that minimum acquaintance with psychology without which he is not fitted to be a citizen of the modern world." Today it can be read and enjoyed in its historical context.
