I think about my editor when I write. She's a good friend, too.

And although I have seen nothing but black crows in my life, it doesn't mean that there's no such thing as a white crow. Both for a philosopher and for a scientist it can be important not to reject the possibility of finding a white crow.

I believe there is something of the divine mystery in everything that exists. We can see it sparkle in a sunflower or a poppy. We sense more of the unfathomable mystery in a butterfly that flutters from a twig--or in a goldfish swimming in a bowl. But we are closest to God in our own soul. Only there can we become one with the greatest mystery of life. In truth, at very rare moments we can experience that we ourselves are that divine mystery.
