If there was some central theme beneath the (more Irish than Greek) stew of intuitions about the nature of human existence – and of fiction – it is perhaps in the alternative title, whose rejection I still sometimes regret: The Godgame. I did intend Conchis to exhibit a series of masks representing human notions of God, from the supernatural to the jargon-ridden scientific, that is, a series of human illusions about something that does not exist in fact, absolute knowledge and absolute power. The destruction of such illusions seems to me still an eminently humanist aim; and I wish there were some super-Conchis who could put the Arabs and the Israelis, or the Ulster Catholics and Protestants, through the same heuristic mill as Nicholas.
