“In France at least, the history of science and thought gives pride of place sciences, sciences of the necessary, all close to philosophy: one can observe in their history the almost uninterrupted emergence of truth and pure reason. The other disciplines, however - those, for example, that concern living beings, languages, or economic facts - are considered too tinged with empirical thought, too exposed to the vagaries of chance or imagery to age old traditions and external events, for it to be supposed that their history could be anything other irregular. At most, they are expected to provide evidence of a state of mind, an intellectual fashion, a mixture of archaism and bold conjecture, of intuition and blindness. But what if empirical knowledge, at a given time and in a given culture, did possess a well defined regularity.”

De Abaitua interview (1998)
Context: There are books that have devastated continents, destroyed thousands. What war hasn’t been a war of fiction? All the religious wars certainly, or the fiction of communism versus the fiction of capitalism – ideas, fictions, shit that people make. They have made a vast impression on the real world. It is the real world. Are thoughts not real? I believe it was Wittgenstein who said a thought is a real event in space and time. I don’t quite agree about the space and time bit, Ludwig, but certainly a real event. It’s only science that cannot consider thought as a real event, and science is not reality. It’s a map of reality, and not a very good one. It’s good, it’s useful, but it has its limits. We have to realise that the map has its edges. One thing that is past the edge is any personal experience. That is why magic is a broader map to me, it includes science. It’s the kind of map we need if we are to survive psychologically in the age that is to come, whatever that is. We need a bigger map because the old one is based on an old universe where not many of us live anymore. We have to understand what we are dealing with here because it is dangerous. It kills people. Art kills.
