Where there is no strife there is decay: 'The mixture which is not shaken decomposes.'

He who hears not me but the logos will say: All is one.

Man, like a light in the night, is kindled and put out.

Character is our destiny.

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

One must know that war is common, justice is strife, and everything happens according to strife and necessity.

You cannot step twice into the same river.
