“We find in them an ignorant and barbarous people, who have long united the most sordid avarice with the most detestable superstition and the most invincible hatred for every people by whom they are tolerated and enriched. Still, we ought not to burn them.”

“Perhaps there is nothing greater on earth than the sacrifice of youth and beauty, often of high birth, made by the gentle sex in order to work in hospitals for the relief of human misery, the sight of which is so revolting to our delicacy. Peoples separated from the Roman religion have imitated but imperfectly so generous a charity.”

“I am ignorant of how I was formed and how I was born. Through a quarter of my lifetime I was absolutely ignorant of the reasons for everything I saw and heard and felt, and was merely a parrot prompted by other parrots... When I sought to advance along that infinite course, I could neither find one single footpath or fully discover one single object, and from the upward leap I made to contemplate eternity I fell back into the abyss of my ignorance.”

“had no need of a guide to learn ignorance”
