"The old man has been long at the fair. He is acquainted with the jugglers at the booths. His curiosity has been satisfied. He no longer cares for the exceptional, the monstrous, the marvelous and deformed. He looks through and beyond the gilding, the glitter and gloss, not only of things, but of conduct, of manners, theories, religions and philosophies. He sees clearer. The light no longer shines in his eyes."

My deeply held belief is that if a god of anything like the traditional sort exists, our curiosity and intelligence are provided by such a god. We would be unappreciative of those gifts (as well as unable to take such a course of action) if we suppressed our passion to explore the universe and ourselves. On the other hand, if such a traditional god does not exist, our curiosity and our intelligence are the essential tools for managing our survival. In either case, the enterprise of knowledge is consistent with both science and religion, and is essential for the welfare of the human species.
