I know nothing except the fact of my ignorance.
He who knows does not speak; He who speaks does not know.
As we acquire more knowledge, things do not become more comprehensible, but more mysterious.
All that we know is nothing, we are merely crammed wastepaper baskets, unless we are in touch with that which laughs at all our knowing.
D. H. Lawrence
All I know about method is that when I am not working I sometimes think I know something, but when I am working, it is quite clear I know nothing.
