There's a huge amount of work on Adam and Eve, from the ancient world to the present. Saint Augustine was obsessed with them.I don't know if it helps my research, but I get a big kick out of Mark Twain, who wrote "The Diaries of Adam and Eve." He wrote very funny stuff on them. I sometimes read things that are loosely related to what I'm thinking and writing about.

In short, it became possible - never easy, but possible - in the poet Auden's phrase to find the mortal world enough.

A comparably capacious embrace of beauty and pleasure - an embrace that somehow extends to death as well as life, to dissolution as well as creation - characterizes Montaigne's restless reflections on matter in motion, Cervantes's chronicle of his mad knight, Michelangelo's depiction of flayed skin, Leonardo's sketches of whirlpools, Caravaggio's loving attention to the dirty soles of Christ's feet.

I believe that it is a whole lifetime of work on Shakespeare's part that enabled him to do what he did. But the question is how you can explain this whole lifetime in such a way to make it accessible and available to us, to me.

Now a Protestant confronting a Catholic ghost is exactly Shakespeare's way of grappling with what was not simply a general social problem but one lived out in his own life.

But if Shakespeare himself is maybe about meaning and truth, I don't know, then he is certainly about pleasure and interest, we start with pleasure and interest, but maybe eventually it gets to meaning and truth.

When I was quite young I came across a collection of [Franz] Kafka stories and read "The Judgment." I was just floored by that story. I couldn't understand it. I still don't. I'm talking about something I read more than 50 years ago. That story left a little scar on me.
