 According to Hutcheson’s metaethic, evaluations are specifically linked to the senses, in particular the internal senses. So, for instance, aesthetic goodness will be determined (in a sense to be discussed in  §1.3)  by the operation of the sense of imagination. Honorable actions will be determined by the operation of the sense of honor. Morally good actions will be determined by the operation of the moral sense, and so on. But one might wonder whether there is such a ready distinction between the internal senses. Given that we can form new ideas given their comparison, and derive pleasure from them, why believe that there is such a sharp distinction between, e.g., the sense of imagination and the moral sense? Put another way, what individuates these senses, sufficient to distinguish evaluative modes?
