This is a breezy volume, written in a free and easy American style, which is addressed purely to a lay audience, indeed, specifically to those suffering from neuroses. It is essentially written on psychoanalytical lines and aims at 'meeting the need for a simple, comprehensive presentation of the Freudian principles.' We must say that the authors have succeeded in their aim. Though the presentation is only very elementary, it is quite accurate so far as it goes. In the glossary appended, we note that repression is defined as 'Expulsion from consciousness of a pain-provoking mental process'. It should be pointed out that this act constitutes only a small part of repression, the greater part of which is occupied with preventing such processes from ever entering consciousness, so that no question of expulsion can arise.

In general, the book can be cordially recommended as being suitable for its purpose. There are few books which it would be better for a nervous invalid to read than this.
