A man of knowledge lives by acting, not by thinking about acting.

We don't know all the answers. If we knew all the answers we'd be bored, wouldn't we? We keep looking, searching, trying to get more knowledge.

I'll come to you with gifts of knowledge, wisdom and truth.

To know what you know and what you do not know, that is true knowledge.

Knowledge is soon changed, then lost in the mist, an echo half-heard.
