Disch's book is certainly designed to provoke, as you can tell from the quotes on the inside cover, nearly all of which contain the word 'provocative' amongst their fulsome praise. You'll also find lots of critics of this book with their eyes bulging out, because Disch has had the temerity to run down their favourite author (such as Heinlein) or suggest the awful truth, that most SF is designed to be read by 12 year olds. But as Disch points out, he has insider knowledge of the science fiction field, and has met nearly all of the SF greats of the 20th Century. Reading this book is like a witty and cynical relative at a wedding giving you the real low down on all the guest's foibles. It is delicious fun. Disch has a sharp tongue and no time for ideologists, religious zealots, charlatans, frauds, the gullible or the self-righteous. In a mordantly funny, and incredibly well written series of essays, he deconstructs the history of Science Fiction, tearing down sacred cows, or pointing out the ones that should have been put out to pasture long ago. The book is about how science fiction has been the vehicle for various movements in modern culture, from feminism and cults to imperialism and fame. He saves his choicest venom for hack writers who start SF religions, and also for Ursula Le Guin, for attempting to rewrite SF history in the image of feminism (a charge for which exhibit A is the Norton Anthology of Science Fiction, a tour d'horizon of the field in which the Big Three, Asimov, Heinlein and Clarke, are not represented). In many ways, The Dreams Our Stuff is Made of is a worthy successor to Kingsley Amis' amusing, but now somewhat dated polemic of the field, New Maps of Hell. As with Amis, you probably won't agree with everything Disch says, and he has a definite tendency to overgeneralise at times. However, his sardonic style of writing, his command of his subject matter, and the sheer gusto of his language will carry you from page one to the end on a tide of fascinating diatribe.
