Knowing many things doesn't teach insight.
All things flow, nothing abides. You cannot step into the same river twice, for the waters are continually flowing on. Nothing is permanent except change.
It is wise to agree that all things are one.
All is flux; nothing stays still.
No man ever steps in the same river twice, for it's not the same river and he's not the same man.
Hide our ignorance as we will, an evening of wine soon reveals it.
