Heraclitus somewhere says that all things are in process and nothing stays still, and likening existing things to the stream of a river he says that you would not step twice into the same river.

War is the mother of everything.
Corpses are more fit to be thrown out than is dung.
You may travel far and wide but never will you find the boundaries of the soul.
