“A wise man sees as much as he ought, not as much as he can.”

“If it be well weighed, to say that a man lieth, is as much to say, as that he is brave towards God and a coward towards men.”

“Can anything be imagined so ridiculous, that this miserable and wretched creature [man], who is not so much as master of himself, but subject to the injuries of all things, should call himself master and emperor of the world, of which he has not power to know the least part, much less to command the whole?”

“Learned we may be with another man's learning: we can only be wise with wisdom of our own.”

“If the pupil proves to be of so perverse a disposition that he would rather listen to some idle tale than to the account of a glorious voyage or to a wise conversation, when he hears one; if he turns away from the drum-beat that awakens young ardour in his comrades, to listen to another tattoo that summons him to a display of juggling; if he does not fervently feel it to be pleasanter and sweeter to return from a wrestling-match, dusty but victorious, with the prize in his hand, than from a game of tennis or a ball, I can see no other remedy that for his tutor to strangle him before it is too late, if there are no witnesses.”

“I do not think that there is so much wretchedness in us as vanity; we are not so much wicked as daft; we are not so much full of evil as of inanity; we are not so much pitiful as despicable.”

“Let this variety of ideas be set before him; he will choose if he can; if not, he will remain in doubt. Only the fools are certain and assured. For if he embraces Xenophon's and Plato's opinions by his own reasoning, they will no longer be theirs, they will be his. He who follows another follows nothing. He finds nothing; indeed he seeks nothing. We are not under a king; let each one claim his own freedom [Seneca]. Let him know that he knows, at least. He must imbibe their ways of thinking, not learn their precepts. And let him boldly forget, if he wants, where he got them, but let him know how to make them his own. Truth and reason are common to everyone, and no more belong to the man who first spoke them than to the man who says them later. It is no more according to Plato than according to me, since he and I understand and see it the same way. The bees plunder the flowers here and there, but afterward they make of them honey, which is all theirs; it is no longer thyme or marjoram. Even so with the pieces borrowed from others; he will transform and blend them to make a work of his own, to wit, his judgment. His education, work, and study aim only at forming this.”
