If you live as if you know nothing you offer yourself the opportunity to learn everything.

I thought to myself: I am wiser than this man; neither of us probably knows anything that is really good, but he thinks he has knowledge, when he has not, while I, having no knowledge, do not think I have.

I’m convinced that there is nothing ​truly good.
Hell, sunshine can wilt a flower.

Human knowledge is but a ripple on the water's surface. To go deeper, we must accept the fact that we don't know everything

Knowledge is marvelous, but wisdom is even better.

Knowledge never grows old; it is eternally young.
