The fairest harmony springs from discord.
What is divine escapes men's notice because of their incredulity.
Everything flows, nothing stays still.
The awake share a common world, but the asleep turn aside into private worlds.
Heraclitus somewhere says that all things are in process and nothing stays still, and likening existing things to the stream of a river he says that you would not step twice into the same river.
It would not be better if things happened to men just as they wish.
