For when is death not within our selves? And as Heracleitus says: “Living and dead are the same, and so are awake and asleep, young and old. The former when shifted are the latter, and again the latter when shifted are the former."

A man's character is his fate.

All is flux; nothing stays still.

Man is most nearly himself when he achieves the seriousness of a child at play.

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.

The nature of things is in the habit of concealing itself.

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