“There's a time and place for everything, and I believe it’s called 'fan fiction'.”

De Abaitua interview (1998)
Context: A god is the idea of a god. The idea of a god is a god. The idea of Glycon is Glycon, if I can enhance that idea with an anaconda and a speaking tube, fair enough. I am unlikely to start believing that this glove puppet created the universe. It’s a fiction, all gods are fiction. It’s just that I happen to think that fiction’s real. Or that it has its own reality, that is just as valid as ours. I happen to believe that most of the important things in the material world start out as fiction. That everything around us was once fiction – before there was the table there was the idea of a table, and the idea of a table before tables was fiction. This is the most important world, the world of fictional things. That’s the world where all this starts.
