From the supposition made by Edwards, that "if activity of nature be the cause why a spirit acts," it has been concluded that he regarded the soul of man as the efficient cause of its volitions, and motive as merely the occasion on which they are put forth or exerted. But surely, those who have so understood the Inquiry, have done so very unadvisedly, and have but little reason to complain, as they are prone to do, that his opponents do not understand him. If Edwards makes mind the efficient cause of volition, what becomes of his famous argument against the self-determining power, by which he reduces it to the absurdity of an infinite series of volitions? "If the mind causes its volition," says he, "it can do so only by a preceding volition; and so on _ad infinitum_." Is not all this true, on the supposition that the mind is the efficient cause of volition? And if so, how can any reader of Edwards, who does not wish to make either his author or himself appear ridiculous, seriously contend that he holds mind to be the efficient, or producing cause of volition? There be pretended followers and blind admirers of President Edwards, who, knowing but little of his work themselves, are ever ready to defend him, whensoever attacked, even by those who have devoted years to the study of the Inquiry, by most ignorantly and flippantly declaring that they do not understand him. These pseudo-disciples will not listen to the charge, that Edwards makes the strongest motive the producing cause of volition; but whether this charge be true or not, we shall see in the following section. SECTION II. OF EDWARDS' USE OF THE TERM CAUSE. WE have already seen that Edwards must be understood as holding motive to be the cause of volition; but still we cannot make up the issue with him, until we have ascertained in what sense he employs the term _cause_. It has been contended, by high authority, that he did not regard motive as the efficient, or producing cause of volition, but only as the occasion or condition on which volition is produced. Hence, it becomes necessary to examine this point, and to settle the meaning of the author, in order that I may not be supposed to misrepresent him, and to dispute with him only about words. The above notion is based on the following passage:
