War is the father and king of all: some he has made gods, and some men; some slaves and some free.
The people must fight on behalf of the law as though for the city wall.
The only thing constant is change
Everything flows and nothing abides. Everything gives way and nothing stays fixed.
Learning many things does not teach understanding
This world... ever was, and is, and shall be, ever-living Fire, in measures being kindled and in measures going out.
