These theologians clearly perceived, that if volition is necessarily determined by motive, and if motive lies in the correlation of desire and object, then, in a being totally depraved, or a being of radically corrupt desires, there can be no ability to good deeds: the deed is as the volition, and the volition is as the strongest desire or the sense of the most agreeable. Hence these theologians refer the conversion of man exclusively to divine influence. The man cannot change his own heart, nor employ any means to that end; for this would imply a volition for which, according to the supposition, he has no ability. Now, at the same time, that this class represent men as unable to love and obey the truths of religion, they engage with great zeal in expounding these truths to their minds, and in urging upon them the duty of obedience. But what is the aim of this preaching? Perhaps one will reply, I know the man cannot determine himself to obedience, but in preaching to him, I am presenting motives which may influence him. But in denying his ability to do good, you deny the possibility of moving him by motives drawn from religious truth and obligation. His heart, by supposition, is not in correlation with truth and duty; the more, therefore, you preach truth and duty, the more intense is the sense of the disagreeable which you awaken. As when you present objects to a man's mind which are correlated to his feelings, the more clearly and frequently you present them, the more you advance towards the sense of the most agreeable or choice. So when you present objects which are not correlated to his feelings, the more clearly and frequently you present them, the more you must advance towards the sense of the most disagreeable, or positive refusal.
