I simply go with what works. And what works is the healthy skepticism embodied in the scientific method. Believe me, if the Bible had ever been shown to be a rich source of scientific answers and enlightenment, we would be mining it daily for cosmic discovery.

There is no science in this world like physics. Nothing comes close to the precision with which physics enables you to understand the world around you.

I can tell you that in my modern life I enjoy language. I enjoy words, their meaning, what they sound like to the ear, what they sound like to the listener. I strive to write the perfect sentence in all that I do, and when I write [the] perfect sentence I know it. If I had a second life I'd be a librettist for Broadway musicals.
