 The argument from motivation depends upon Edwards' identification of willing or choosing with one's strongest inclination or preference. Since choosing just is a prevailing inclination, it is logically impossible to choose in the absence of a prevailing motive. If there is a prevailing motive, however, then the will is necessarily determined by it, for if the will were to choose contrary to a prevailing motive, the agent would have two opposed preponderant inclinations at the same time. All choices, therefore, are necessarily determined.
