 Moral “learning” is, thus, less a matter of ingesting and digesting moral principles to apply to circumstances—there were no inviolable principles for Jefferson, as morality was a matter of sensing the right thing to do in circumstances—but of placing faith in the capacity of one’s moral sense to “decide” the right course of action without the corruptive influence of reason or peer pressure (TJ to Martha Jefferson, 11 Dec. 1783, TJ to Peter Carr, 19 Aug. 1785 and 10 Aug. 1787).
