Papers of John Adams, volume 19
Truth, sir, is born of the clash of ideas. Mr. Turgot could not have been confronted by a more worthy opponent; both devoted to liberty and to the happiness of men, you reach toward the same goal by different means, and you have both illuminated the way.
It is Mr. de Valnais2 who brought me your book, and my customary sojourn at Versailles for the Assembly of Notables does not permit me to thank him in person. Please accept my sentiments of gratitude for your remembrance and your gift and the sincere expression of the esteem and the attachment with which I have the honor to be, sir, your most humble and most obedient servant
My mother and wife wish me to convey all their respects to you.
