"Superficial knowledge … is hurtful to those who possess true genius; for it necessarily draws them away from their main object, wastes their industry over details and subjects foreign to their needs and natural talent, and lastly does not serve, as they flatter themselves, to prove the breadth of their mind. In all ages there have been men of very moderate intelligence who knew much, and so on the contrary, men of the highest intelligence who knew very little. Ignorance is not lack of intelligence, nor knowledge a proof of genius."

“The falsest of all philosophies is that which, under the pretext of delivering men from the embarrassment of their passions, counsels idleness and the abandonment and neglect of themselves.”

“Reason and emotion counsel and supplement each other. Whoever heeds only the one, and puts aside the other, recklessly deprives himself of a portion of the aid granted us for the regulation of our conduct.”

“Great men in teaching weak men to reflect have set them on the road to error.”

“No one says in the morning: A day is soon past, let us wait for the night. On the contrary, in the evening we consider what we shall do the next day. We should be very sorry to spend even one day at the mercy of time and bores. … Who can be certain of spending an hour without being bored, if he takes no care to fill even that short period according to his pleasure. Yet what we cannot be certain of for an hour, we sometimes feel assured of for life, and say: “If death is the end of everything, why give ourselves so much trouble? We are extremely foolish to make such a pother about the future”—that is to say, we are extremely foolish not to entrust our destinies to chance, and to provide for the interval which lies between us and death.”

“It is unjust to exact that men shall do out of deference to our advice what they have no desire to do for themselves.”
