Knowing and Not Knowing.

What one knows is always less than what one doesn't know. Therefore, one must place more importance on what one doesn't know than upon what one knows. But how can one place importance on what one doesn't know? First, and most tellingly, by being humble about what one knows. Second, by being skeptical about what anyone else claims to know. Third, by investing large amounts of one's time, energy, and resources into knowing more.
