Actually I wrote it before he did, while trying to simulate him. It was great confirmation of my simulation skills when his book was published, exactly because there is some uncanny overlap. In the beggining of my book I talk about this a bit, it was one of three coincidences which gave me full retrospective confidence in the project. I can simulate Dennett, the question that remains unanswered so far is, can I install that ability into other minds through words?
