That is good image, he said. Well, I shall tell you. My thesis is this: I want you to believe.
To believe what?
To believe in things that you cannot. Let me illustrate. I heard once of an American who so defined faith: 'that faculty which enables us to believe things which we know to be untrue.' For one, I follow that man. He meant that we shall have an open mind, and not let a little bit of truth check the rush of a big truth, like a small rock does a railway truck. We get the small truth first. Good! We keep him, and we value him; but all the same we must not let him think himself all the truth in the universe.
