“Confidence in others' honesty is no light testimony of one's own integrity.”

“I care not so much what I am in the opinion of others, as what I am in my own.”

“All we do is to look after the opinions and learning of others: we ought to make them our own.”

“There is indeed a certain sense of gratification when we do a good deed that gives us inward satisfaction, and a generous pride that accompanies a good conscience…These testimonies of a good conscience are pleasant; and such a natural pleasure is very beneficial to us; it is the only payment that can never fail. “On Repentance”

“To censure my own faults in some other person seems to me no more incongruous than to censure, as I often do, another's in myself. They must be denounced everywhere, and be allowed no place of sanctuary.”

“It is an absolute perfection and virtually divine to know how to enjoy our being rightfully. We seek other conditions because we do not understand the use of our own, and go outside of ourselves because we do not know what it is like inside. Yet there is no use our mounting on stilts, for on stilts we must still walk on our own legs. And on the loftiest throne in the world we are still sitting only on our own rump.”

“Would I fortify myself against the fear of death, it must be at the expense of Seneca: would I extract consolation for myself or my friend, I must borrow it from Cicero.  I might have found it in myself, had I been trained to make use of my own reason.  I do not like this relative and mendicant understanding; for though we could become learned by other men's learning, a man can never be wise but by his own wisdom.”
