This book on Medical Psychology is conceived to meet the needs of what appears to be a very important revolution that is rapidly coming about in medical education. In a previous work of mine, Foundations of Psychiatry, I undertook to outline the subject of a psychology sufficient to form a basis for the understanding of the neuroses and the psychoses. The object of the present book is a much broader one, and while I have drawn upon the material of my Foundations quite freely, especially in outlining the fundamental biological concepts which are strategically valuable for introducing and coming to an understanding of psychological questions, still it is no less than an attempt to formulate those principles which are at the basis of an understanding of the psychological factor which is necessarily present in all disease. A reading of the book will lead to an understanding of this very broad statement, and if the reader finds himself in agreement with me that disease, no matter of what part of the body or how caused, has in every instance a psychological aspect, then he will also, I am sure, feel in agreement with me that psychology should be an essential part of the medical curriculum on the same basis as physiology. This at any rate is the conviction of the author, and it is to meet this need that the present book is written. (PsycINFO Database Record (c) 2015 APA, all rights reserved)
