The Early Stories of Philip K. Dick

In The Defenders, the Soviet and American survivors of a nuclear holocaust have created vast underground tunnels, so as to continue the war on the surface via remote control robots. When a robot from the surface is found not to be radioactive, a team of American scientists returns topside to investigate this anomaly. Expecting to see massive devastation, the scientists are unprepared for the shocking truth that awaits them.

Englishman Edward Prendick finds himself shipwrecked on the open ocean. When a passing ship takes him aboard and revives him, things are starting to look less gloomy for the young scientist. Yet little does he know things about to get much worse. He is taken to an abandoned island occupied only by Dr. Moreau, a disgraced English scientist for his unethical treatment of live creatures. Prendick finds that the Doctor has been up to old habits, using the island's animals to create animal-human hybrids.

UN forces have retreated to a moon base in the aftermath of early Soviet victories in a nuclear conflict. In response, the UN forces developed special robots, called "Claws", which feature spinning blades and rudimentary artificial intelligence. Six years later, the Soviet leadership asks for negotiations to end the war. A UN officer travels back to earth to discover that not only have the Claws learned to replicate themselves, they have also created a much deadlier cyborg that threatens humanity itself.

In "The Variable Man", Earth (The Terran System) is in a cold war with the older, corrupt Centaurian System, which suppresses Terra from exploring space and expanding its borders. When a devastating new weapon called Icarus is developed by Terra, everyone expects the odds to tip in Terra's favor. But the computers calculating these odds find an unknown variable that throws off the odds. A time traveler from 1913 known as Thomas Cole has arrived. Can this variable man from the past rescue mankind from a catastrophic future?

Trapped in a London laboratory during a worker uprising in 1924, ex-artillery officer and physics instructor Jeremy Tuft awakens 150 years later - in a neo-medieval society whose inhabitants have forgotten how to build or operate machinery. Not only have his fellow Londoners forgotten most of what humankind used to know, before civilization collapsed, but they don't particularly care to re-learn any of it. Though he is at first disconcerted by the failure of his own era's smug doctrine of Progress, Tuft eventually decides that post-civilized life is simpler, more peaceful.
