Li a crítica da Ursula (tem link na wiki), toda a frase final é ótima:
He has done, in The Iron Dream, something as outrageous as what Borges talks about doing in "Pierre Menard" (the rewriting of Don Quixote, word for word, by a twentieth-century Frenchman): he has attempted a staggeringly bold act of forced, extreme distancing. And distancing, the pulling back from "reality" in order to see it better, is perhaps the essential gesture of SF. It is by distancing that SF achieves aesthetic joy, tragic tension, and moral cogency. It is the latter that Spinrad aims for, and achieves. We are forced, in so far as we can continue to read the book seriously, to think, not about Adolf Hitler and his historic crimes--Hitler is simply the distancing medium--but to think about ourselves: our moral assumptions, our ideas of heroism, our desires to, lead or to be led, our righteous wars. What Spinrad is trying to tell us is that it is happening here.
