In writing a biography on the author, Brian Stableford placed several of Dick's short stories in a context that established their relationship to the author's personal hardships. "...it always seemed to him K. Dick that his career was a catalogue of undeserved disappointments and the record of his published work a travesty of his true ambitions." The personal problems which Dick struggled throughout his life provided fuel for several of the anxiety driven themes for his short stories. In Dick's early work, Stableford highlighted recurring themes in those most popular. These included paranoid suspicions; the dangerous hostility of "seemingly innocent entities"; and "the mechanization of the environment and the computerization of political decision-making". Stories in which androids and robots are a danger to the protagonist include "Autofac", "Colony", and "Vulcan's Hammer". However, "The Last of the Masters", Stableford contends, was an exception to Dick's common dystopic portrayals of technology, given Stableford's interpretation of Bors as an altruist, who was "benign" in its role.
