“A wrongdoer is often a man who has left something undone, not always one who has done something.”

“Which is recorded of Socrates, that he was able both to abstain from, and to enjoy, those things which many are too weak to abstain from, and cannot enjoy without excess. But to be strong enough both to bear the one and to be sober in the other is the mark of a man who has a perfect and invincible soul.”

“In this flowing stream, then, on which there is no abiding, what is there of the things which hurry by on which a man would set a high price? It would be just as if a man should fall in love with one of the sparrows which fly by, but it has already passed out of sight.”

“No man is happy who does not think himself so.”

“A man should always have these two rules in readiness. First, to do only what the reason of your ruling and legislating faculties suggest for the service of man. Second, to change your opinion whenever anyone at hand sets you right and unsettles you in an opinion, but this change of opinion should come only because you are persuaded that something is just or to the public advantage, not because it appears pleasant or increases your reputation.”

“There is no man so blessed that some who stand by his deathbed won't hail the occasion with delight.”

“Some things are hurrying into existence and others are hurrying out of it and of that which is coming into existence, part is already extinguished. In this flowing stream then, on which there is no abiding, what is there of things which hurry on by on which a man would set a high price. It would be just as if a man should fall in love with one of the sparrows which fly by but has already passed out of sight.”
