Comment on style/language

In Valis, Philip K. Dick portrays himself as a successful science fiction writer, former drug abuser, and sufferer of a severe mental breakdown that causes him to project an alter ego whom he calls Horselover Fat. He claims that talking in the third person about Fat provides needed objectivity. Dick writes comfortably in the idiom of the 1970s, dealing with the exploding drug culture and political unrest of the era of Vietnam and Richard M. Nixon. He several times mentions singer Linda Ronstadt, who is then at the peak of her career.
