Dr. Jenner’s Experiment

  “March 28th, 1797, I inoculated this girl and carefully rubbed the variolous matter into two slight incisions made upon the left arm. A little inflammation appeared in the usual manner around the parts where the matter was inserted, but so early as the fifth day it vanished entirely without producing any effect on the system.” —Edward Jenner (1749–1823). “The Three Original Publications on Vaccination Against Smallpox.” Portrait of Edward Jenner, painted by James Northcote in either 1803 or 1823

Seneca, Moral Letter 17, “On Philosophy and Riches”

 

“Nay, your plan should be this: be a philosopher now, whether you have anything or not, – for if you have anything, how do you know that you have not too much already? – but if you have nothing, seek understanding first, before anything else. . . 


. . . I shall borrow from Epicurus: ‘The acquisition of riches has been for many men, not an end, but a change, of troubles.’” (Seneca, Moral Letter 17, “On Philosophy and Riches”)
