Cabot calls the "sin of impersonality" is a grievous sin when directed toward another person, but most of us could stand a good deal of ingrowing impersonality without any harm.
The fact that the human machine can run itself without a hitch in the majority of cases is witness to its inherent tendency toward health. People were living and living well through all the centuries before the science of psychology was formulated. But not with all people do things run so smoothly. There were demoniacs in Bible times and neurotics in the Middle Ages, as there are nervous invalids and half-well people to-day. Psychology has a real contribution to make, and in recent years its lessons have been put into language which the average man can understand.
Psychology is not merely interested in abstract terms with long names. It is no longer absorbed merely in states of consciousness taken separately and analyzed abstractly. The newer functional psychology is increasingly interested in the study of real persons, their purposes and interests, what they feel and value, and how they may learn to realize their highest aspirations. It is about ordinary people, as they think and act, in the kitchen, on the street cars, at the bargain-counter, people in crowds and alone, mothers and their babies, little children at play, young girls with their lovers, and all the rest of human life. It is the science of you, and
as such it can hardly help being interesting.
While psychology deals with such topics as the subconscious mind, the instincts, the laws of habit, and association of ideas and suggestion, it is after all not so much an academic as a practical question. These forces govern the thought you are thinking at this moment, the way you will feel a half-hour from now, the mood you will be in to-morrow, the friends you will make and the profession you will choose, besides having a large share in the health or ill-health of your body in the meantime.
Summary
Perhaps it would be well before going farther to summarize what we have been saying. Here in a nutshell is the kernel of the subject:
Disease may be caused by physical or by psychic forces. A "nervous" disorder is not a physical but a psychic disease. It is caused not by lack of energy but by misdirected energy; not by overwork or nerve-depletion, but by misconception, emotional conflict, repressed instincts, and buried memories. Seventy-five per cent. of all cases of ill-health are due to psychic causes, to disjointed thinking rather than to a disjointed spine. Wherefore, let us learn to think right.
In outline form, the trouble in a neurosis may be stated something like this:
Lack of adaptation to the social environment—caused by
Lack of harmony within the personality—caused by
Misdirected energy—caused by
Inappropriate emotions—caused by
Wrong ideas or ignorance.
