Everything flows and nothing abides; everything gives way and nothing stays fixed... Cool things become warm, the warm grows cool; the moist dries, the parched becomes moist... It is in changing that things find repose.
Man is on earth as in an egg.
Men who wish to know about the world must learn about it in its particular details.
Stupidity is better kept a secret than displayed.
The only thing constant is change
Dogs bark at a person whom they do not know.
