The conscious transference of habits. When habits are consciously acquired, they may be consciously transferred with modifications to situations slightly different from those in which they were first learned. Merely mechanical habits are a hindrance in any save the most mechanical work. An alert and conscious method of learning, which means the development of habits as methods of control, will enable the individual to modify habits acquired in slightly different circumstances to new situations where the major conditions remain the same. To be merely habitual is to be at best an efficient machine, utterly unable to do anything except to run along certain grooves, to respond like an animal trained to certain tricks. It means, moreover, a loss of richness in experience. When a profession becomes routinated it becomes meaningless; a mere making of the wheels go round. The spirit of alert and conscious inquiry must be maintained if life is not to become a mere repeated monotony.

An alert and conscious adjustment of habits to a changing environment constitutes intelligence. The technique of this adjustment is the technique of thinking or of reflective behavior, which we shall examine in more detail in the following chapter.

Emotion. All human action, whether on the plane of instinct, habit, or reflection, is, to a lesser or greater degree, accompanied by emotion. While there is considerable controversy among psychologists as to the precise nature of emotion, and the precise conditions of its causation, its general features and significance are fairly clear. Emotion may be most generally defined as an awareness or consciousness on the part of the individual of his experiences, both those in which he is the actor and those in which he is being passively acted upon. This awareness or consciousness is not detached intellectual perception, but is accompanied by, as it is by some held to be merely the consciousness of, certain specific bodily disturbances. Thus the emotions of fear and grief are not cold and abstract perceptions of situations that belong in the classes dangerous or deplorable, respectively. The awareness of these situations by the individual is intimately and invariably connected with certain outward bodily manifestations and certain inner organic disturbances. Fear, rage, pity, and the like are not unimpassioned judgments, but highly charged physical changes. So close, indeed, is the connection between specific bodily conditions and the subjective or inner consciousness that we call emotion, that James and Lange simultaneously came to the conclusion that emotions are nothing more nor less than the blending of the complex organic changes that occur in any given emotional state. Thus James:

What kind of an emotion of fear would be left if the feeling neither of quickened heart-beats nor of shallow breathing, neither of trembling lips nor of weakened limbs, neither of goose-flesh nor of visceral stirrings, were present, it is impossible for me to think. Can anyone fancy the state of rage, and picture no ebullition in the chest, no flushing of the face, no dilation of the nostrils, no clenching of the teeth, no impulse to vigorous action, but in their stead limp muscles, calm breathing, and a placid face? The present writer, for one, certainly cannot. The rage is as completely evaporated as the sensations of its so-called manifestations, and the only thing that can possibly be supposed to take its place is some cold blooded and dispassionate judicial sentence, confined entirely to the intellectual realm, to the effect that a certain person or persons merit chastisement for their sins. In like manner of grief; what would it be without its tears, its sobs, its suffocation of the heart, its pang in the breast-bone? A feelingless cognition that certain circumstances are deplorable, and nothing more.[1]

[Footnote 1: James: Psychology, vol. II, p. 452.]

Indeed, so completely did James think the emotions were explicable as the inner feeling of the complex organic sensations which go to make up each of them that he did not think it misleading to say "we feel sorry because we cry, angry because we strike, afraid because we tremble; we do not cry, strike, or tremble because we are sorry, angry, or fearful, as the case may be."

Whether or not emotions are completely to be explained as the inner or subjective aspect of the complex of organic disturbances which accompany fear, rage, and the like, and which are caused immediately by the perception of the appropriate objects of these emotions, it is certainly true that emotional awareness and bodily disturbances are very closely connected.[1]

[Footnote 1: Recent experiments by Dr. Cannon at Harvard have shown the specific bodily disturbances which accompany anger, fear, etc. In particular, Dr. Cannon, and others, have noted that in the emotional conditions of fear and anger the glands, located near the kidneys, discharge a fluid into the blood stream, which fluid stimulates the heart to activity, constricts the blood vessels of the internal organs, causes the liver to pour out into the blood its stores of sugar, and affects in one way or another all the organs of the body. The general effect is to put the body into a state of preparedness for the activities connected with the emotion, whether flight in the case of fear, attack as in the case of anger. This has led Professor Woodworth to define emotion as, at least in part, "the way the body feels when it is prepared for a certain reaction." See the latter's Dynamic Psychology, pp. 51-59.]

Various attempts have been made to classify the emotions which are, in ordinary experience, infinitely subtle and complex. The subtlety and variety of emotion James explains as the result of the subtle and imperceptible differences in the complex of sensations which occur in any given situation. In general, it has been recognized that the emotions are very closely connected with the primary tendencies of man. McDougall, for example, says that each of the great primary impulses is accompanied by an emotion. Indeed, McDougall considers, as earlier noted, that the emotion is the affective or conscious aspect of an instinct which, at the same time, has a perceptual and impulsive aspect; that, in the case of fear, the perceptual aspect is the instinctive mechanism for recognizing objects of danger, the impulsive aspect is the tendency toward flight, and the affective aspect is the inner feeling or awareness of fear. Thus, for McDougall, the tender emotion is the emotional aspect of the instinct of pity, anger of the instinct of pugnacity, which is, as an impulse, the tendency to strike and destroy.

As a matter of fact, as McDougall himself admits, emotions are seldom experienced in unmixed forms, and it is very difficult to reduce the infinite variety of emotional experiences to any primary forms. One may well agree with James that "subdivisions [in the psychological demarcation of the emotions] are to a great extent either fictitious or unimportant, and ... pretenses to accuracy, a sham." In general, one may say that emotions are closely connected with the native tendencies of human beings and are aroused by both their fulfillment, their conflict, and their frustration. The variety of emotions results from the fact that no single one of our instincts is stimulated at a time, and that the peculiar specific quality of each emotional experience is due to the specific point of conflict, fulfillment, or frustration in each particular case. It may be further noted that those emotions are, in general, pleasantly toned which accompany the fulfillment or the approach to the fulfillment of a native disposition; and those are unpleasantly toned which accompany their frustration or conflict. The depth and intensity of the emotional disturbance seem to depend on the degree and extent to which strong instinctive or habitual impulses have become involved. For as habits of action may be acquired, so also may emotions become associated habitually with them. The emotional disturbances connected with the fulfillment, frustration, and conflict of habits may be just as intense as those connected with similar phenomena in the case of instincts.
