The volume gathers Dick's early stories, including works like 'Beyond the Door,' 'The Defenders,' and 'Second Variety.' They explore paranoia, war, and autonomous machines.
Androids, simulacra, and empathy tests recur as ways to probe what actually makes someone human. The moral weight falls on empathy rather than biology.
