Heraclitus

It is necessary to understand that war is common, strife is customary, and all things happen because of strife and necessity.

Sleeping people live in their own world; only those who are awake have a world in common.

If there were no sun, all the stars would not suffice to prevent its being night.

οὐκ ἐμοῦ, ἀλλὰ τοῦ λόγου ἀκούσαντας ὁμολογεῖν σο­φόν ἐστιν ἓν πάντα εἶναί

Everything flows and nothing abides; everything gives way and nothing stays fixed.

The road up and the road down is one and the same

One must realize that war is common, and justice strife, and that all things come to be through strife and are (so) ordained.

Men forget where the way leads and what they meet with every day seems strange to them.We should not act and speak like men asleep.

The immortals are mortal, the mortals immortal, each living in the other's death and dying in the other's life.

The bow (βιός) is called life (βίος) but its work is death.

إن الحمير لتفضل القش علي الذهب

To fight with desire is hard: whatever it wishes it buys at the price of a soul.

For souls it is death to become water, and for water death to become earth. Water comes into existence out of earth, and soul out of water.

It would not be better if things happened to people just as they wish.

You cannot step twice into the same river, for different and ever different waters flow down.
