In the introduction the author puts forth the purpose of this book as follows:

Vegetative nervous system response patterns are inextricably associated with cerebrospinal response patterns, but when either system relaxes, the other tends to relax likewise. Accordingly the physiology and control of the emotions is opened to investigation and to practical application. The present volume will be devoted to exposition of this thesis and to examples in education and medicine.

The cerebrospinal response patterns which are of particular concern to the author are those which involve muscle. In the following chapters he defines emotions, notes the close connection between stimulus, some form of central integration, output, and most importantly, the feedback to the central nervous system (CNS) from the effector apparatus (viz, musculature). In this regard he sees impulses from the muscular system as having an important role in the maintenance of CNS activity
