Chapter 10, Footnote #02
When the effect or tendency of a motive is to determine a man to forbear to act, it may seem improper to make use of the term motive: since motive, properly speaking, means that which disposes an object to move. We must however use that improper term, or a term which, though proper enough, is scarce in use, the word determinative. By way of justification, or at least apology, for the popular usage in this behalf, it may be observed that even forbearance to act, or the negation of motion (that is, of bodily motion) supposes an act done when such forbearance is voluntary. It supposes, to wit, an act of the will, which is as much a positive act. as much motion, as any other act of the thinking substance.
