It is weariness to keep toiling at the same things so that one becomes ruled by them.
When men dream, each has his own world. When they are awake, they have a common world.
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.
Even sleepers are workers and collaborators on what goes on in the universe.
Though wisdom is common, yet the many live as if they had a wisdom of their own.
Abundance of knowledge does not teach men to be wise.
