There is nothing permanent except change.

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

There is nothing permanent except change. Nothing is permanent except change. The only constant is change. Change is the only constant. Change alone is unchanging.

Time is a game played beautifully by children.

All things are in flux; the flux is subject to a unifying measure or rational principle. This principle (logos, the hidden harmony behind all change) bound opposites together in a unified tension, which is like that of a lyre, where a stable harmonious sound emerges from the tension of the opposing forces that arise from the bow bound together by the string.

Stupidity is better kept a secret than displayed.

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