Signs and Symptoms: Thomas Pynchon and the Contemporary World by Peter L. Cooper situates Pynchon's achievement within the philosophical, literary, and scientific currents of modern thought, emphasizing his place among American counterrealists. While earlier novelists grounded their work in the traditions of realism and naturalism--offering psychologically rounded characters, coherent narration, and cause-and-effect logic--Pynchon and his contemporaries, including Heller, Vonnegut, Barth, Burroughs, and Nabokov, resist such conventions. Their fiction portrays diminished, often cartoonish characters adrift in grotesque and absurd worlds shaped by entropy, conspiratorial forces, or unfathomable chance. These counterrealists deliberately frustrate narrative expectations, undermining traditional concepts of identity, causality, and meaning to reflect a twentieth-century reality that itself feels fragmented, unstable, and menacing. For Pynchon in particular, paranoia, conspiracy, and epistemological uncertainty become structural motifs, dramatizing the tension between too little structure--cosmic drift toward entropy--and too much structure--bureaucratic control and technological domination. Cooper argues that although Pynchon mocks humanity's compulsion to impose order through patterns and interpretive systems, he also acknowledges their necessity. His fiction stages this paradox through unreliable narrators, labyrinthine plots, proliferating symbols, and scientific metaphors that highlight the limits of perception and the inevitability of projection. In works such as *The Crying of Lot 49* and *Gravity's Rainbow*, characters struggle to interpret evidence, never knowing whether they uncover hidden systems or simply overlay their own delusions upon reality. This epistemological anxiety, shared across counterrealist fiction, links Pynchon to Borges's infinite regress of invented realities and Barth's metafictional games, yet Pynchon maintains a more urgent political and historical focus. By tracing the interplay of paranoia, grotesque absurdity, and entropic decline in Pynchon's oeuvre, Cooper illuminates the novelist's distinctive position at the crossroads of modern fiction, where satire, science, and philosophy converge to expose the precariousness of knowledge, identity, and control in the contemporary world.
