31From John Adams to Benjamin Rush, 4 December 1805 (Adams Papers)
I am half inclined to be very angry with you for destroying the Anecdotes and documents you had collected for private Memoirs of the American Revolution. From the Memories of Individuals, the true Springs of Events and the real motives of Actions are to be made known to Posterity. The Period in the History of the World, the best understood, is that of Rome from the time of Marius to the Death...
32From John Adams to Benjamin Rush, 25 January 1806 (Adams Papers)
The new Edition of your medical Works, mentioned in your favour of the sixth of this month, have been committed to mr Shaw: my Nephew whom you know, and will be sent to me from Boston in due time. Many of those compositions I have read and shall read again with much pleasure, and shall make them as generally useful as I can among the Physicians in my Neighbourhood: but as I feel as few as I...
33From John Adams to Benjamin Rush, 26 March 1806 (Adams Papers)
Your favour of the fifteenth is received. In a cornfield, which I had manured with seaweed and Marsh mud, in a compost with other materials, I found, last fall, two plants of an uncommon Appearance which I Suspected to be the Kali: because—they resembled the descriptions of it which I had read in the Dictionary of natural History and in the Œconomical Dictionary, both of which quote Monsieur...
34From John Adams to Benjamin Rush, 22 June 1806 (Adams Papers)
Your Letter of the tenth, like all others from your pen, notwithstanding all your apologies, was a cordial to my Spirit. I must confess to you, that the data, upon which you reason from the Prophecies concerning the future amelioration of the condition of mankind, are too obscure and uncertain, to authorize us to build any System upon them for the conduct of Nations—It is well to understand as...
35From John Adams to Benjamin Rush, 23 July 1806 (Adams Papers)
I have two of your Letters to acknowledge, at once. The Treatise on the Spleen I have read, and been entertained by it, perhaps more than I should have been if I had been better acquainted with the sciences on which it depends. Your medical Speculations are to me as entertaining as Romances of which I am a great lover: but they are as much in request among the learned of your Profession: so...
36From John Adams to Benjamin Rush, 19 September 1806 (Adams Papers)
Thanks for your favour of Aug. 22d. My Experience is perfectly conformable to yours, respecting silent Men. Silence is most commonly design and Intrigue. In Franklin it was very remarkable, because he was naturally a great Talker. I have conversed with him frequently in his garrulous humours, and his Grandson, or Son, Billy has told me that he never knew a greater Talker than his Grandfather....
37From John Adams to Benjamin Rush, 11 November 1806 (Adams Papers)
When I recd your favour of the 24. Oct, I Soberly expected a grave dissertation on the Perfectibility of Man. Although I thank you for the political information you give me, which is amusing and although I doubt not your Physiological researches will result in something usefull to the publick, yet, as I have ever considered all Arts Sciences and Litterature as of small importance in comparison...
38From John Adams to Benjamin Rush, 22 December 1806 (Adams Papers)
I thank you for yours of the twenty fifth of November. I was in hopes you would have explained to me the System of human Perfectibility which was is claimed as the Invention of Dr Priestley. The System of the French Œconomists I took some Pains, more than five and twenty years ago, to understand; but could not find one Gentleman among the Statesmen, Phylosophers and Men of Letters, who...
39From John Adams to Benjamin Rush, 2 February 1807 (Adams Papers)
You make me very happy when you Say, that you agree with me upon the Subject of the Perfectibility of Man. Let every Man endeavor to amend and improve one and We Shall find ourselves in the right Road to all the Perfection We are capable of: but this rule Should by no means exclude our utmost exertions to amend and improve others, and in every Way and by all means in our Power to ameliorate...
40From John Adams to Benjamin Rush, 12 April 1807 (Adams Papers)
Your favour of the 3d is received; I am willing to allow you Philosophers your opinion of the universal gravitation of matter, if you will allow mine that there is in some souls a principle of absolute levity that buoys them irresistibly into the Clouds. Whether you call it etherial spirit or inflammable air it has an uncontroulable tendency to ascend & has no capacity to ascertain the height...
