TO THOMAS LAW, ESQ./POPLAR FOREST, June 13, 1814.: "DEAR SIR,-The copy of your Second Thoughts on Instinctive Impulses, with the letter accompanying it, was received just as I was setting out on a journey to this place, two or three days distant from Monticello. I brought it with me and read it With great satisfaction, and With the more as it contained exactly my own creed on the foundation of morality in man. It is really curious that on a question so fundamental, such a variety of opinions should have prevailed among men, and those, too, of the most exemplary virtue and first order of understanding. It shows how necessary was the care of the Creator in making the moral principle so much a part of our constitution as that no errors of reasoning or of speculation might lead us astray from its observance in practice."
