Low class men desire wealth;middle class men both wealth and respect; but the noble, honour only; hence honour is the noble man's true wealth.

The only true wisdom is in knowing you know nothing.

Wisdom is a weapon to ward off destruction; It is an inner fortress which enemies cannot destroy.

Wisdom usually grows up on us like calluses when we are old, gnarled and bent.

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

When you want wisdom and insight as badly as you want to breathe, it is then you shall have it.
