Life is an interpretation of a series of facts, and that interpretation is really what life is about. So the division between non-fiction and fiction has a certain logic, but it's a very limited one. And by and large, it isn't helpful.

How does one say in the jargon of musicology that my sould was pulled out of me and thrown up in the air, to be tossed about by the music. How does one say that I breathed, that I existed, in harmony with the ups and downs of those notes. What kind of notes both elevate and cast down, exalt and crush?

The planet is populated by human beings, of which there are only two sexes, and the role of the writer is to explore otherness, other realities. So the idea of a man exploring what it's like to be a woman doesn't strike me as being that wild or crazy an idea.

Sometimes I got my majors mixed up. A number of my fellow religious-studies students - muddled agnostics who didn't know which way was up, who were in the thrall of reason, that fool's gold for the bright - reminded me of the three-toed sloth; and the three-toed sloth, such a beautiful example of the miracle of life, reminded me of God.

I must say a word about fear. It is life's only true opponent. Only fear can defeat life. It is a clever, treacherous adversary, how well I know. It has no decency, respects no law or convention, shows no mercy. It goes for your weakest spot, which it finds with unerring ease. It begins in your mind, always. One moment you are feeling calm, self-possessed, happy. Then fear, disguised in the garb of mild-mannered doubt, slips into your mind like a spy.

If you stumble over mere believability, what are you living for? Love is hard to believe, ask any lover. Life is hard to believe, ask any scientist. God is hard to believe, ask any believer. What is your problem with hard to believe? Reason is excellent for getting food, clothing and shelter. Reason is the very best tool kit. Nothing beats reason for keeping tigers away. But be excessively reasonable and you risk throwing out the universe with the bathwater

Why can't reason give greater answers? Why can we throw a question further than we can pull in an answer? Why such a vast net if there's so little fish to catch?
