STIMULI TO VOLUNTARY MOVEMENT
The Voluntary Motor Consciousness. The general analysis already found convenient for the reactive consciousness holds for the voluntary. We find that in all cases of intended bodily movement there is, first, a reason why we will the reaction; second, the actual decision or act of will; and third, the resulting movement. All the "reasons why," taken together, constitute stimuli to voluntary movement, and they may be considered first.
I. Interest in an Object. The most evident characteristic of intentional action is that something is intended, i. e., that a presentation of some kind is set before consciousness. The notion of an end foreseen, which we found absent in instinct and impulse, and undefined in ethical feeling, here becomes explicit. Psychology finds here, in common phraseology, one of its safest distinctions.
Yet it is easy to see that an object thus presented or apperceived must carry some interest in order to be pursued. I will to move my leg, either that I may walk--my present interest; or that I may relieve a strain--also my present interest. Some degree of present emotional interest, therefore, may be said to be the most general stimulus to volition.____________________
