Mailer famously labeled writing the spooky art. He was right. There's a lot of frontal lobe blather, a lot of pencil-sharpening and knuckle-cracking and drafting and chat, but the big decisions are made in the locked subconscious, decisions not just on the writing but on the conditions for writing: I resolve on the one story I've never told and lo! Here I sit, holed up in a house that means nothing to me, bone-certain no other places will do. Art, even the humble autobiographer's, invokes occult necessities.
