We can know only that we know nothing. And that is the highest degree of human wisdom.

The only true wisdom is in knowing you know nothing.

Once and for all, there are many things I choose not to know.-Wisdom sets limits even to knowledge.

Long is the night to him who is awake; long is a mile to him who is tired; long is life to the foolish who do not know the true law.

How blissful it is, for one who has nothing. Attainers-of-wisdom are people with nothing. See him suffering, one who has something, a person bound in mind with people.

The ignorant man is an ox. He grows in size, not in wisdom.
