"You don't just write whatever comes into your head while you're sitting there in front of the typewriter. When I wrote UBIK, I got about twelve pages done and couldn't think of anything else, so l just wrote whatever came into my mind. I wrote it from my unconscious: I let the right hemisphere of my brain do all the thinking, and I was as surprised as anybody as to what came out. In France, of course, it's considered a great novel because it doesn't make any sense; in France, it's a roman de pataphysique. Ever since Alfred Jarry hit town, they've loved stuff that doesn't make any sense. Maybe it does make sense when you translate it into French. Maybe I'm a great writer in France because I've got good translators."
