These actions are interesting to study in connexion with the will, but rather in the way of contrast than of similarity. 383 There is probably a deep community in the foundations of the two classes of movements; but, in their more obvious aspect, and for all psychological purposes, they are opposed. It is common to apply to the Reflex class the name “involuntary.”
Secondly. The movements in yawning, laughter, sobbing; the altered action of the heart, the bowels, the kidneys, the skin, in Fear,—are allied with sensations or feelings; but they are not correctly classed with the Will; in fact, some of them are performed through involuntary muscles. A different view must be taken of these effects. They are the inseparable physical accompaniments of feeling; the physical side or counterpart of the mental fact; in their absence the feeling itself would not exist. Fear would not be fear, if the emotional state were not attended with a series of physical effects, partly of movement, partly of altered secretions. These physical accompaniments supply the appearances known to all men as the expression of feeling; which although to a great degree made up of movements, is totally distinct from the voluntary promptings of the feelings. The smile that accompanies a pleasure tasted is one thing: the activity inspired to prolong the enjoyment is another thing. The two kinds of movement are frequently mingled; thus, in acute pains, the cries and contortions of feature are the embodiment of the feeling; the gestures and movements of the body, may be partly expression, but are also attempts to obtain relief. Expression in its purity is well seen in a shock of surprise; a state which being often entirely neutral as regards pleasure or pain, has no voluntary prompting whatsoever. Every feeling has a certain definite physical embodiment with much or with little outward display; this belongs to the feeling as such; it is a phenomenon of feeling or emotion, and not of volition.
Thirdly. The operation of Ideas, in such instances as involuntary imitation, contagious convulsions, the influence of the imagination,—is a genuine source of actions, but is yet to be distinguished from the Will. When the idea of a certain medicine produces the very same effect as the medicine actually applied, when a person yawning makes the beholder yawn, 384 or when, standing on the brink of a precipice, one is tempted to jump down,—there is no intervention of the will properly so called; on the contrary, there may be a conflict between the influence of the idea and the true volitional promptings. The characteristic feature of the voluntary activity is to follow pleasure and to retreat from pain; some of the tendencies growing out of an idea are in the direction of pain.
This, in many respects remarkable, phenomenon is better assigned to the Intellectual part of our nature, although it has consequences on our actions. When a sensation passes into an idea, it still retains, in a diminished form, many of its characteristic properties. The sensation of a savoury morsel in the mouth is accompanied with a gush of saliva; the corresponding idea in any way aroused, as when just commencing to eat, induces the very same flow, expressed by the phrase “the mouth watering.” The mode of interpreting the phenomenon is the announcement of a pregnant law of the mind (two-sided like the mind itself), that the idea is embodied in the same tracks as the sensation, although commonly in a weaker form. There is a standing mental determination, whereby all ideas tend to work themselves out into full actuality; a power that the will and other influences are constantly employed in checking. The sight of a person yawning gives the idea of the act; and the idea, unless counteracted, brings forth the reality. The sight of a precipice gives very forcibly the idea of something falling headlong down, and that idea possesses the mind of the spectator so strongly that but for a restraining volition, he would act it out in his own person.
By far the most interesting application of the law is to explain the workings of Sympathy, in the form of purely beneficent disinterested impulses. Allusion has already been made to the law, in this peculiar aspect, in a former [note] (Chap. XXIII. p. 302).
These three great classes of phenomena being withdrawn from the region of the Will, the remaining facts mentioned in the text can be viewed in a clearer light.
1. It is justly stated that the Will is an extensive and 385 laborious acquisition, pursued, especially at the commencement, in the midst of considerable difficulties.
2. In the mature will, the immediate antecedent of a voluntary act is an idea of the thing to be done. This is true, but not the precise, nor the whole truth.
3. The author’s mode of viewing the influence of Attention points to the really fundamental and typical fact of the Will. He says, Attention is merely another name for the engrossing effect of a pleasurable or a painful sensation. “Having a pleasurable or painful sensation, and attending to it, seem not to be two things, but one and the same thing.” That is to say, there is a power in pleasure as such, and in pain as such, to stimulate action or movement with reference to the pleasure or the pain. This is the nearest approach that is made in the text to a statement of the law of voluntary action.
The law has been differently expressed. Locke said, the will moves to the greatest uneasiness, which is no doubt the fact. Still, by a wider induction, we obtain a more comprehensive, as well as more accurate, generalization.
