Do not take a dick for a Silverberg, for example. Philip K. Dick was a tormented man, addicted to amphetamines, particularly marked by anguish and German philosophy (Kant, Hegel, Nietzsche). So there's rarely home: linear stories with heroes, ships exploding and beautiful love affairs. Dick sometimes recall Cioran is a being who protects the world by cynicism and the absurd. Where delusions about sheep or empathetic inability of humans in Blade Runner or fixing neurotic human in all his novels, on trivialities and leaks in the imagination (like dollhouses combined drug God came in the Centauri) ... It is with Dick that there is a mystical quest that the mine and he seems at the same time moving away from the pathetic. Many of his characters are anxious, cowards or totally crazy! Still, this remains a genius deconstructs the narrative, where it is the disjointed impressions, subjectivity perceived that outweigh story of an omnipotent narrator. Dick is perhaps closest in his writing a Carlos Fuentes that any SF writer ...
Yes, it is not easy to read Dick, but SF is not a kind of epic tales lingered for-es teens!
