Throughout his works, Thomas Pynchon uses various animal characters to narrate fables that are vital to postmodernism and ecocriticism. Thomas Pynchon’s Animal Tales: Fables for Ecocriticism examines case studies of animal representation in Pynchon’s texts, such as alligators in the sewer in V.; the alligator purse in Bleeding Edge; dolphins in the Miami Seaquarium in The Crying of Lot 49; dodoes, pigs, and octopuses in Gravity’s Rainbow; Bigfoot and Godzilla in Vineland and Inherent Vice; and preternatural dogs and mythical worms in Mason & Dixon and Against the Day. Through this exploration, Keita Hatooka illuminates how radically and imaginatively the legendary novelist depicts his empathy for nonhuman beings. Furthermore, by conducting a comparative study of Pynchon’s narratives and his contemporary documentarians and thinkers, Thomas Pynchon’s Animal Tales leads readers to draw great lessons from the fables, which stimulate our ecocritical thought for tomorrow.
