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. If, however, the desire fails to find its immediate fruition, if it is frustrated, consciousness of it may become exceedingly intense. There is the constant thought of the object, a vivid feeling of tension, of a striving to attain the object. Desire may become an obsession, a torment filling the horizon, and the volition in which it finds its fruition stands forth as a marked relief. This condition of things may be brought about by the inhibition occasioned by the physical impossibility of attaining the object; but it may also be brought about by the struggle of incompatible desires among themselves. The man is drawn in different directions, he is subject to various tensions, and he becomes acutely conscious that he is impelled to move in several ways and is moving in none.
