If there is something we cannot know, we must necessarily abandon it as an intellectual problem. For example, I do not know for what reason the universe has come into being, and shall never know. Therefore I must drop this question as a scientific or intellectual problem. But if an idea about it is offered to me—in dreams or in mythic traditions—I ought to take note of it. I even ought to build up a conception on the basis of such hints, even though it will forever remain a hypothesis which I know cannot be proved.
