A collection of stories written in the 50s by one of the greats of SF. There I found all the great themes of SF: robots, androids, the universe after the War, the confrontation between animal society or a more "natural" and techno world, the existence of human capabilities sensory over-developed (in fact one discovers that the precog of "Minority Report" existed in the universe "Dickien" long before the writing of the novel in question). A very enjoyable read.
