 To nephew Peter Carr (19 Aug. 1785), Jefferson says that the god-given moral sense, innate and instinctual, is as much a part of a person’s nature as are the senses of hearing and seeing, or as is a leg or arm. Jefferson’s comparisons to hearing and sight invite depiction of the moral sense tied to a bodily organ, like the heart (TJ to Maria Cosway, 12 Oct. 1785). Like strength of limbs, it too is given to persons in a greater or lesser degree, and can be made better or worse through exercise or its neglect.
