The claws were bad enough in the first place--nasty, crawling little death-robots. But when they began to imitate their creators, it was time for the human race to make peace--if it could Philip K. Dick said of his story Second Variety My grand theme--who is human and who only appears as human?--emerges most fully. Unless we can individually and collectively be certain of the answer to this question, we face what is, in my view, the most serious problem possible. Without answering it adequately, we cannot even be certain of our own selves. Reviewing the story, critic Zack Handlen wrote, 'Second Variety' is grim, violent, and suspenseful. . . . While most of the twists are easy to spot once you discover the main plot--basically 'Are you or aren't you a machine'-- they still have an impact, and Dick makes his point quite clearly. Besides the title story, this collection also includes nine more classic Philip K. Dick tales: Piper in the Woods, Beyond the Door, The Crystal Crypt, The Defenders, The Gun, The Skull, The Eyes Have It, Mr. Spaceship, and the novella The Variable Man--260 pages of mind-bending prose from the master of weird science fiction.
