 One ought to resist the temptation to act viciously in circumstances when vice will not be detected. He tells Carr (19 Aug. 1785) to act always and in all circumstances as if everyone in the world were looking at him. Jefferson bids grandson Thomas Jefferson Randolph (24 Nov. 1808) to appeal to moral exemplars before acting, and he lists Small, Wythe, and Peyton Randolph. “I am certain that this mode of deciding on my conduct, tended more to correctness than any reasoning powers I possessed.” Thus, one can use the moral sense unerringly, or relatively so, if one disregards the intrusions of reason and assumes that all of one’s actions are under the scrutiny of cynosures—i.e., there will be no temptation to act from the pressure of peers. In another letter to Carr (10 Aug. 1787), Jefferson disadvises his nephew to attend lectures on moral philosophy and appeals counterfactually to a ham-handed creator. “He who made us would have been a pitiful bungler if he had made the rules of our moral conduct a matter of science.” Here and  elsewhere,[17]  Jefferson is explicit that reason is uninvolved in moral “judgments.”
