'If a manic J. G. Ballard and a depressive David Lodge got together, they might produce something like The Quantity Theory of Insanity. But Will Self's world is all his own'

Martin Amis

'This hilarious black satire seethes with wonderfully weird ideas and bizarre images, written with a delicate precision'

Literary Review

'Will Self's The Quantity Theory of Insanity is as disturbing as satire ought to be and these days seldom is. Also it is unashamedly funny as well as chilling, presented with an air of cunning repose'

Guardian

'Self savages any human institution or being that smacks of ponderosity. And he writes like a devil'

Mail on Sunday

'Very funny and very good, with that unmistakable sign of the genuine comic writer: absurdity unfurls logically from absurdity, but always as a mirror of what we are living in - and wish we didn't'

Doris Lessing
