"No one can speak well, unless he..." - Quote by Marcus Tullius Cicero

“It is the character of a brave and resolute man not to be ruffled by adversity and not to desert his post.”

“Friendship is not to be sought for its wages, but because its revenue consists entirely in the love which it implies.”

“The chief recommendation is modesty, then dutiful conduct toward parents, then affection for kindred.”

“When you admonish a wrongdoer, do so gently, that it may not lead to hostility.”

“When a person cannot deceive himself the chances are against his being able to deceive other people.”

“Curiosity is only vanity. Most frequently we wish not to know, but to talk. We would not take a sea voyage for the sole pleasure of seeing without hope of ever telling.”

“You can’t go on “seeing through” things forever. The whole point of seeing through something is to see something through it. To “see through” all things is the same as not to see.”

“A man who examines each subject from a philosophical standpoint cannot neglect them: he has to omit nothing, and state the truth about each topic.”

“My father's little library consisted chiefly of books in polemic divinity, most of which I read, and have since often regretted that, at a time when I had such a thirst for knowledge, more proper books had not fallen in my way since it was now resolved I should not be a clergyman.”
