"Reproof is a medicine like mercury or opium; if it be improperly administered it will do harm instead of good."

“There is no method more likely to cure passion and rashness, than the frequent and attentive consideration of one's own weaknesses: this will work into the mind an habitual sense of the need one has of being pardoned, and will bring down the swelling pride and obstinacy of heart, which are the cause of hasty passion.”

“Do not endeavour to shine in all companies. Leave room for your hearers to imagine something within you beyond all you have said. And remember, the more you are praised, the more you will be envied.”

“I considered, that history is the inexhaustible mine, out of which political knowledge is to be brought up.”

“If you happen into company where the talk runs into party, obscemty, scandal, folly, or vice of any kind, you had better pass for morose or unsocial, among people whose good opinion is not worth having, than shock your own conscience by joining in conversation which you must disapprove of.”

“If a great person has omitted rewarding your services, do not talk of it; perhaps he may not yet have had an opportunity, for they have always on hand expectants innumerable, and the clamorous are too generally gratified before the deserving; besides, it is the way to draw his displeasure upon you, which can do you no good, but make bad worse. If the services you did were voluntary, you ought not to expect any return, because you made a present of them unasked; and a free gift is not to be turned into a loan, to draw the person you have served into debt. If you have served a great person merely with a view to self-interest, perhaps he is aware of that, and rewards you accordingly: nor can you justly complain: he owes you nothing; it was not him you meant to serve.”

“If you would have a right to account of things from illiterate people, let them tell their story in their own way; if you put them upon talking according to logical rules, you will confound them.”
