Writing a novel is one of those modern rites of passage, I think, that lead us from an innocent world of contentment, drunkenness, and good humor, to a state of chronic edginess and the perpetual scanning of bank statements.

I accepted that a new kind of hate had emerged, silent and disciplined, a racism tempered by loyalty cards and PIN numbers. Shopping was now the model for all human behaviour, drained of emotion and anger.

It was an excess of fantasy that killed the old United States, the whole Mickey Mouse and Marilyn thing, the most brilliant technologies devoted to trivia like instant cameras and space spectaculars that should have stayed in the pages of Science Fiction . . . some of the last Presidents of the U.S.A. seemed to have been recruited straight from Disneyland.

Their violence (the jungle wars of the '70s), and all violence for that matter, reflects the neutral exploration of sensation that is taking place, within sex as elsewhere and the sense that the perversions are valuable precisely because they provide a readily accessible anthology of exploratory techniques.

Civilised life, you know, is based on a huge number of illusions in which we all collaborate willingly. The trouble is we forget after a while that they are illusions and we are deeply shocked when reality is torn down around us.

I take for granted that for the imaginative writer, the exercise of the imagination is part of the basic process of coping with reality, just as actors need to act all the time to make up for some deficiency in their sense of themselves.

Hell is out of fashion - institutional hells at any rate. The populated infernos of the 20th century are more private affairs, the gaps between the bars are the sutures of one's own skull. A valid hell is one from which there is a possibility of redemption, even if this is never achieved, the dungeons of an architecture of grace whose spires point to some kind of heaven. The institutional hells of the present century are reached with one-way tickets, marked Nagasaki and Buchenwald, worlds of terminal horror even more final than the grave.
