Those unmindful when they hear, for all they make of their intelligence, may be regarded as the walking dead.

War is the father and king of all: some he has made gods, and some men; some slaves and some free.

One must know that war is common, justice is strife, and everything happens according to strife and necessity.

And some men are as ignorant of what they do when awake as they are forgetful of what they do when asleep.

Everything changes but change itself. Everything flows and nothing remains the same... You cannot step twice into the same river, for other waters and yet others go flowing ever on.

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 father of all things.
