All is flux, nothing stays still.
Nothing endures but change.
Although the logos is common to all, the many live as if they had private understanding.
Much learning does not teach a man to have intelligence.
Strife is the source and the master of all things.
The path up and down is one and the same.
Everything comes about by way of strife and necessity.
It is not possible to step twice into the same river.
Character is a man's guiding destiny.
