CHAPTER XI
IMPULSE, DESIRE, AND WILL
31. IMPULSE.—Commands and prohibitions address themselves to man as a voluntary agent. But it seems right to treat as willed by man much more than falls under the head of conscious and deliberate volition. We do not hesitate to make him responsible for vastly more; and yet common sense does not, when enlightened, regard men as responsible for what is recognized as falling wholly beyond the direct and indirect control of their wills.
Motions due to even the blindest of impulses are not to be confounded with those brought about by external compulsion. They may have the appearance of being vaguely purposive, although we would never attribute purpose to the creature making them. The infant that cries and struggles, when tormented by the intrusive pin, the worm writhing in the beak of a bird,—these act blindly, but it does not appear meaningless to say that they act. The impulse is from within.
Some impulses result in actions very nicely adjusted to definite ends. Such are winking, sneezing, swallowing. These reflexes may occur as the mechanical response to a given stimulus. They may occur without our being conscious of them and without our having willed them.
Yet such responses to stimuli are not necessarily unconscious and cut off from voluntary control. He who winks involuntarily when a hand is passed before his eyes may become conscious that he has done so, and may, if he chooses, even acquire some facility in controlling the reflex. One may resist the tendency to swallow when the throat is dry, may hold back a sneeze, or may keep rigid the hand that is pricked by a pin. That is to say, actions in their origin mechanical and independent of choice may be raised out of their low estate, made the objects of attention, and brought within the domain of deliberate choice.
Furthermore, many actions which, at the outset, claimed conscious attention and were deliberately willed may become so habitual that the doer lapses into unconsciousness or semi-unconsciousness of his deed. They take on the nature of acquired reflexes. The habit of acting appears to have been acquired by the mind and then turned over to the body, that the mind may be free to occupy itself with other activities. The man has become less the doer than the spectator of his acts; perhaps he is even less than that, he is the stage upon which the action makes its appearance, while the spectator is his neighbor. The complicated bodily movements called into play when one bites one's nails had to be learned. It requires no little ingenuity to accomplish the act when the nails are short. Yet one may come to the stage of perfection at which one bites one's nails when one is absorbed in thought about other things. And one may learn to slander one's neighbor almost as mechanically and unthinkingly as one swallows when the throat is dry.
When we speak of man's impulses, we are using a vague word. There are impulses which will never be anything more. There are impulses which may become something more. There are impulses which are no longer anything more. Impulses have their psychic aspect. At its lower limit, impulse may appear very mechanical; at its upper, one may hesitate to say that desire and will are wholly absent. It is not wise to regard impulse as lying wholly beyond the sphere of will.
32. DESIRE.—At its lower limit, desire is not distinguished by any sharp line from mere impulse. Is the infant that stretches out its hands toward a bright object conscious of a desire to possess it? Or does the motion made follow the visual sensation as the wail follows the wound made by the pin? At a certain stage of development the phenomena of desire become unmistakable. The idea of something to be attained, the notion of means to the attainment of an end, the consciousness of tension, may stand out clearly. The analysis of the psychologist, which finds in desire a consciousness of the present state of the self, an idea of a future state, and a feeling of tension towards the realization of the latter, may represent faithfully the elements present in desire in the higher stages of its development, but it would be difficult to find those elements clearly marked in desire which has just begun to differentiate itself from impulse. There may be a desire where there can scarcely be said to be a self as an object of consciousness; one may desire where there is no clear consciousness of a future state as distinct from a present one.
Moreover, the consciousness of desire may be faint and fugitive, as it may be intense and persistent. Desire is the step between the first consciousness of the object and the voluntary release of energy which works toward its attainment. This step may be passed over almost unnoticed. The thought of shifting my position when I feel uncomfortable may be followed by the act with no clear consciousness of a tension and its voluntary release. The mere thought, itself but faintly and momentarily in consciousness, appears to be followed at once by the act, and desire and will to be eliminated. It does not follow that they are actually eliminated; they may be present as fleeting shadows which fail to attract attention.
