 Locke, in fact, adds something of a meta-moral dimension to this epistemological point by suggesting that as rational beings it is our “proper Imployment” to contemplate morality. In Book IV of the Essay, where Locke concludes that morality is, like mathematics, a human science (and, properly-speaking, knowledge), Locke draws a teleological lesson—since we are clearly fitted with the capacity for discerning our moral duty, then that is what we ought to do: “I think I may conclude, that Morality is the proper Science and Business of Mankind in general.” (Essay, 4.12.11) Humans must, he argues, employ reason in the pursuit of that which “they are most adapted to, and follow the direction of Nature, where it seems to point us out the way” (Essay, 4.12.11). The fact that many people do not or cannot devote contemplative hours to their moral duties is something Locke will consider in his account of moral motivation, however, the key point here is that humans have a teleological makeup that allows for rational certainty with regard to divine moral law.
