CHAPTER IINTRODUCTION Science. Before attempting to define psychology, it will be helpful to make some inquiry into the nature of science in general. Science is knowledge; it is what we know. But mere knowledge is not science. For a bit of knowledge to become a part of science, its relation to other bits of knowledge must be found. In botany, for example, bits of knowledge about plants do not make a science of botany. To have a science of... more...

RELIGION AND NEUROLOGY It is with no small amount of trepidation that I take my place behind this desk, and face this learned audience. To us Americans, the experience of receiving instruction from the living voice, as well as from the books, of European scholars, is very familiar. At my own University of Harvard, not a winter passes without its harvest, large or small, of lectures from Scottish, English, French, or German representatives of the... more...

INTRODUCTION Having read with much care the proof sheets of this book, I am prepared to say three things about it, and it gives me pleasure to say them here. THE BOOK IS WELL NAMED. "THE UNFOLDING LIFE." Turn which way we will, we see life unfolding all about us, and yet how faintly are its mysteries understood! And is it not the one thing above all others, which teachers, mothers, fathers and all of us, need to understand? It is well... more...

INTRODUCTION The medical profession is justly conservative. Human life should not be considered as the proper material for wild experiments. Conservatism, however, is too often a welcome excuse for lazy minds, loath to adapt themselves to fast changing conditions. Remember the scornful reception which first was accorded to Freud's discoveries in the domain of the unconscious. When after years of patient observations, he finally decided to... more...

CHAPTER IWHAT IS PSYCHOLOGY? Wise men study the sciences which deal with the origins and development of animal life, with the structure of the cells, with the effect of various diseases upon the tissues and fluids of the body; they study the causes of the reactions of the body cells to disease germs, and search for the origin and means of extermination of these enemies to health. They study the laws of physical well-being. They seek for the... more...

Sixth and seventh days, pleasure in moderately bright daylight (3, 4). Ninth and tenth days, sensitiveness greater at waking than soon afterward (3).

THE MIND AND ITS EDUCATION CHAPTER I THE MIND, OR CONSCIOUSNESS We are to study the mind and its education; but how? It is easy to understand how we may investigate the great world of material things about us; for we can see it, touch it, weigh it, or measure it. But how are we to discover the nature of the mind, or come to know the processes by which consciousness works? For mind is intangible; we cannot see it, feel it, taste it, or handle... more...

FORWARD The present book is a continuation from "Psychoanalysis and the Unconscious." The generality of readers had better just leave it alone. The generality of critics likewise. I really don't want to convince anybody. It is quite in opposition to my whole nature. I don't intend my books for the generality of readers. I count it a mistake of our mistaken democracy, that every man who can read print is allowed to believe that he can read all... more...

A DOMINIE IN DOUBT I. "Just give me your candid opinion of A Dominie's Log; I'd like to hear it." Macdonald looked up from digging into the bowl of his pipe with a dilapidated penknife. He is now head-master of Tarbonny Public School, a school I know well, for I taught in it for two years as an ex-pupil teacher. Six days ago he wrote asking me to come and spend a holiday with him, so I hastily packed my bag and made for Euston. This evening... more...
