After criticizing psychology as a science, the author of this work takes a number of discrete facts from it and from physiology in an effort to show that the study of mind can be scientific—that expansion of the simple reflex arc with various neuron combinations explains how the mind works. Examples from simple biologic forms demonstrate the increase in complexity of behavior, and the author uses neurologic principles in the manner of elementary textbooks of physiology. When the author studies higher mechanisms than the stepping reflex of the dog, he develops complicated explanations although still adhering to reflexology as his basic method. He illustrates his theory by means of diagrams designed to show the passage of the nervous
