1784 December 27. (Marquis de Chastellux). "Let me describe to you a man, not yet forty, tall, and with a mild and pleasing countenance, but whose mind and understanding are ample substitutes for every exterior grace. An American, who without ever having quitted his own country, is at once a musician, skilled in drawing; a geometrician, an astronomer, a natural philosopher, legislator, and statesman. A senator of America, who sat for two years in that famous Congress which brought about the revolution...a governor of Virginia, who filled this difficult station during the invasions of Arnold, of Phillips, and of Cornwallis; a philosopher, in voluntary retirement, from the world, and public business, because he loves the world, inasmuch only as he can flatter himself with being useful to mankind...For no object had escaped Mr. Jefferson; and it seemed as if from his youth he had placed his mind, as he has done his house, on an elevated situation, from which he might contemplate the universe."

My Fellow Labourer in Congress, eight or nine years ago, upon many arduous Tryals, particularly in the draught of our Declaration of Independence and in the formation of our Code of Articles of War, and Laws for the Army.

1797 November 3. (John Adams to John Quincy Adams). "You can witness for me how loath I have been to give him up. It is with much reluctance that I am obliged to look upon him as a man whose mind is warped by prejudice and so blinded by ignorance as to be unfit for the office he holds.

1802-1805. (John Adams, Autobiography). "Mr. Jefferson had been now about a year a member of Congress, but had attended his duty in the House but a very small part of the time and when there had enver spoken in public: and during the whole time I sat with him in Congress, I never heard him utter three sentences together. The most of a spech he ever made in my hearing was a gross insult on religion, in one or two sentences, for which I gave him immediately the reprehension which he richly merited...Mr. Jefferson had the reputation of a masterly Pen..."

1824 November 12-14. (Frances Wright to Julia and Harriet Garnett). "...the greatest of American's surviving veterans. I found the venerable patriot and statesman much what I expected to see him, perhaps rather from the descriptions I had heard and read than from any portrait I had seen--all of which except one exquisite drawing of Stuart's in possession of the family, are decided caricatures. His face has nothing of that elaborate length and breadth of chin invariably attached to it in all the prints and paintings that have come under my observation but exhibits still in its decaying outline, and fallen and withered surface the forms of symmetry and deep impress of character and intellect..."
