All is flux, nothing is stationary.
Hide our ignorance as we will, an evening of wine soon reveals it.
Whoever cannot seek the unforeseen sees nothing for the known way is an impasse.
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.
Wisdom consists in speaking and acting the truth.
The most beautiful ape is ugly when compared to a human. The wisest human will seem like an ape when compared to a god with respect to wisdom, beauty, and everything else.
