349 “First, every act of will must have an object. He that wills, must will something; and that which he wills is called the object of his volition. As a man cannot think without thinking of something, nor remember without remembering something, so neither can he will without willing something. Every act of will, therefore, must have an object; and the person who wills must have some conception, more or less distinct of what he wills.
“A second observation is, that the immediate object of will must be some action of our own.”
There are two assertions here which demand our attention; 1, that what is willed is an action of our own; 2, that to such will a conception, that is, an Idea, more or less distinct, of this action of ours, is indispensable.
He adduces some particulars, in illustration, which impart something more of precision to his meaning.
“A healthy child, some hours after its birth, feels the sensation of hunger, and, if applied to the breast, sucks and swallows its food very perfectly. We have no reason to think, that before it ever sucked, it has any conception of that complex operation, or how it is performed. It cannot, therefore, with propriety, be said that it wills to suck.” It appears, from this example, that the muscular actions, which are performed by Sensation, Dr. Reid distinguishes from those, which he calls voluntary; that he denominates voluntary, those only which are performed by Ideas. It also appears fully, from the example, that the Idea of the action willed, which he considers the foundation of volition, must, in all cases, be subsequent to the performance of the act by Sensation; in other 350 words, that the idea cannot exist but in consequence of the sensation.
What has yet been advanced, however, is not a full explanation of the subject. For, after it is admitted that the motion of the muscles is, in all cases, the immediate effect of the appropriate Idea, there is still one class which all men agree to call involuntary; another which many contend are voluntary. It now remains that we inquire wherein the difference consists.
There is one point which is established by the mere statement, and which goes a certain way towards the solution of the question. Since the action of the muscles follows upon the existence of the Idea, whatever calls up the Idea produces the action. The Question, then, may be resolved into these two: In what manner is the Idea called up in cases called involuntary? In what manner is it called up in those called voluntary?
In the cases called not voluntary, I doubt not, it will be easily admitted, that the Idea is raised in the way of ordinary association, by a preceding Sensation, or Idea. In the yawning which proceeds from the sight of another person yawning, the idea is called up by a Sensation. In the laughter which is excited either by ideas suggested to us from without, or ideas which spring up in our associated trains, the idea which is proximate to the muscular action is, of course, called up by an Idea.
There appears no circumstance by which the cases called voluntary are distinguished from the involuntary, except that in the voluntary there exists a Desire. Shedding tears at the hearing of a tragic story, we do not desire to weep: laughing at the recital 351 of a comic story, we do not desire to laugh.[62] But when we elevate the arm to ward off a blow, we desire to lift the arm; when we turn the head to look at some attractive object, we desire to move the head. I believe that no case of voluntary action can be mentioned, in which it would not be an appropriate expression, to call the action desired.
[62] These are emotional and not volitional manifestations. They are the natural signs, expression, or embodiment of a feeling, as feeling, and apart from the power to move the will, which is a separate fact.—B.
