Man, like a light in the night, is kindled and put out.
Presumption must be quenched even more than a fire.
Men that love wisdom must be acquainted with very many things indeed.
The awake share a common world, but the asleep turn aside into private worlds.
There is but one world common for those who are awake, but when men are asleep, each turns away into a world of his own.
And some men are as ignorant of what they do when awake as they are forgetful of what they do when asleep.
