The waking have one common world, but the sleeping turn aside each into a world of his own

No man ever steps in the same river twice, for it's not the same river and he's not the same man.

Stupidity is better kept a secret than displayed.

Everything changes but change itself. Everything flows and nothing remains the same... You cannot step twice into the same river, for other waters and yet others go flowing ever on.

War is the father of all things.

For when is death not within our selves? And as Heracleitus says: “Living and dead are the same, and so are awake and asleep, young and old. The former when shifted are the latter, and again the latter when shifted are the former."

It is better to hide ignorance, but it is hard to do this when we relax over wine.
