Once we view morals not as innate instincts but as learnt traditions, their relation to what we ordinarily call feelings, emotions or sentiments raises various interesting questions. For instance, although learnt, morals do not necessarily always operate as explicit rules, but may manifest themselves, as do true instincts, as vague disinclinations to, or distastes for, certain kinds of action. Often they tell us how to choose among, or to avoid, inborn instinctual drives.
