The first key to greatness is to be in reality what we appear to be.

I know what I do not know.

Nobody knows anything, but I, knowing nothing, am the smartest man in the world.

I know that I am intelligent, because I know that I know nothing.

Be as you wish to seem.

The end of life is to be like unto God; and the soul following God, will be like unto Him; He being the beginning, middle, and end of all things.

This is...self-knowled ge-for a man to know what he knows, and what he does not know.
