 The real problem, however, is that Hutcheson just claims—hypothesizes—that we possess a unique, original moral sense. If asked why we have a moral sense, his reply is that God implanted it in us. Although in his critical phase Hume freely borrows many of Hutcheson’s arguments to criticize moral rationalism, his rejection of a God-given moral sense puts him on a radically different path from Hutcheson in his constructive phase. One way of understanding Hume’s project is to see it as an attempt to naturalize Hutcheson’s moral sense theory. He aims to provide a wholly naturalistic and economical explanation of how we come to experience the moral sentiments that also explains why we approve of the different virtues. In the course of explaining the moral sentiments, Hutcheson’s idea of an original moral sense disappears from Hume’s account of morality.
