Introduction

Originally published in 1906. How the mind of man can be strengthened, widened, and made a more efficient instrument through the application of modern scientific and physiological knowledge is a question of intense interest. It is now a universally accepted fact that the body is capable of improvement by the application of hygienic rules, and that thereby the life of man and his happiness are bettered. It is also proved by physiology that mental action is absolutely co-related with brain action, and it therefore does not admit of doubt that the mind may also be bettered through brain and bodily hygiene. This book includes chapters on the mind machinery in the brian; how the brain mechanism works in regard to mind; and te mental hygiene of bodily disease.
