Jefferson, Thomas (1743-1826)

Letter to John Adams (March 14, 1820)

Monticello

1820

"When I meet with a proposition beyond finite comprehension, I abandon it as I do a weight which human strength cannot lift, and I think ignorance, in these cases, is truly the softest pillow on which I can lay my head."

Monticello, March 14, 1820. Dear Sir, A continuation of poor health makes me an irregular correspondent. I am, therefore, your debtor for the two letters of January 20th and February 21st. It was after you left Europe that Dugald Stewart, concerning whom you inquire, and Lord Dare, second son of the Marquis of Lansdowne, came to Paris. They brought me a letter from Lord Wycombe, whom you knew. I became immediately intimate with Stewart, calling mutually on each other and almost daily, during their stay at Paris, which was of some months. Lord Dare was a young man of imagination, with occasional flashes indicating deep penetration, but of much caprice, and little judgment. He has been long dead, and the family title is now, I believe, in the third son, who has shown in Parliament talents of a superior order. Stewart is a great man, and among the most honest living. I have heard nothing of his dying at top, as you suppose. Mr. Ticknor, however, can give you the best information on that subject, as he must have heard particularly of him when in Edinburgh, although I believe he did not see him. I have understood he was then in London superintending the publication of a new work. I consider him and Tracy as the ablest metaphysicians living; by which I mean investigators of the thinking faculty of man. Stewart seems to have given its natural history from facts and observations; Tracy its modes of action and deduction, which he calls Logic and Ideology; and Cabanis, in his Physique et Morale de l'Homme, has investigated anatomically, and most ingeniously, the particular organs in the human structure which may most probably exercise that faculty. And they ask why may not the mode of action called thought, have been given to a material organ of peculiar structure, as that of magnetism is to the needle, or of elasticity to the spring by a particular manipulation of the steel. They observe that on ignition of the needle or spring, their magnetism and elasticity cease. So on dissolution of the material organ by death, its action of thought may cease also, and that nobody supposes that the magnetism or elasticity retire to hold a substantive and distinct existence. These were qualities only of particular conformations of matter; change the conformation, and its qualities change also. Mr. Locke, you know, and other materialists, have charged with blasphemy the spiritualists who have denied the Creator the power of endowing certain forms of matter with the faculty of thought. These, however, are speculations and subtleties in which, for my own part, I have little indulged myself. When I meet with a proposition beyond finite comprehension, I abandon it as I do a weight which human strength cannot lift, and I think ignorance, in these cases, is truly the softest pillow on which I can lay my head. Were it necessary, however, to form an opinion, I confess I should, with Mr. Locke, prefer swallowing one incomprehensibility rather than two. It requires one effort only to admit the single incomprehensibility of matter endowed with thought, and two to believe, first that of an existence called spirit, of which we have neither evidence nor idea, and then secondly how that spirit, which has neither extension nor solidity, can put material organs into motion. These are things which you and I may perhaps know ere long. We have so lived as to fear neither horn of the dilemma. We have, willingly, done injury to no man; and have done for our country the good which has fallen in our way, so far as commensurate with the faculties given us. That we have not done more than we could, cannot be imputed to us as a crime before any tribunal. I look, therefore, to the crisis, as I am sure you also do, as one "qui summum nec metuit diem nec optat." In the meantime be our last as cordial as were our first affections.
