Men, in the common use of language, and in the expression of their common and generally received sentiments, affirm that an individual has any thing in his power when it can be controlled by volition. Their connexion of power does not arise from the connexion of volition with its cause, but from the conception of volition as itself a cause with its effects. Thus the hand of a malicious man when moved to strike, having for its antecedent a volition; and if withheld from striking, having for its antecedent likewise a volition; according to the common usage of language, he, as the subject of volition, has the power to strike or not to strike. Now as it is "improperly said that he cannot perform those external voluntary actions which depend on the will, it is in some respects more improperly said, that he is unable to exert the acts of the will themselves; because it is more evidently false, with respect to these, that he cannot if he will; for to say so is a downright contradiction; it is to say he _cannot_ will if he _does_ will: and, in this case, not only is it true that it is easy for a man to do the thing if he will, but the very willing is the doing." (ibid.) It is improper, according to this, to say that a man cannot do a thing, when nothing is wanting but an act of volition; for that is within our power, as far as it can be within our power, which is within the reach of our volition. It is still more improper to say that a man is unable to exert the acts of the will themselves, or unable to produce volitions. To say that a man has power to produce volitions, would imply that he has power to will volitions; but this would make one volition the cause of another, which is absurd. But, as it is absurd to represent the will as the cause of its own volitions, and of course to say that the man has ability to produce his volitions, it must be absurd likewise to represent the man as _unable_, in any particular case, to produce volitions, for this would imply that in other cases he is able. Nay, the very language is self-contradictory. If a man produce volitions, he must produce them by volitions; and if in any case he is affirmed to be unable to produce volitions; then this inability must arise from a want of connexion between the volition by which the required volition is aimed to be produced, and the required volition itself. So that to affirm that he is unable to will is equivalent to saying, that he cannot will _if he will_--a proposition which grants the very point it assumes to deny. "The very willing is the doing," which is required.
