Taking his cues from Thoreau, Stevens, and Ammons, from Wittgenstein, Barthes and Eco, from Bruno Latour and Michel Serres, from the philosophers Rorty, Hacking, and Dennett, and from the biologists Ernst Mayr and Stephen Jay Gould, author Dana Phillips emphasizes an eclectic but pragmatic approach to a variety of topics. His subject matter includes the doctrine of social construction; the question of what it means to be interdisciplinary; the disparity between scientific and literary versions of realism; the difficulty of resolving the tension between facts and values, or more broadly, between nature and culture; the American obsession with personal experience; and the intellectual challenges posed by natural history. Those challenges range from the near-impossibility of defining ecological concepts with precision to the complications that arise when a birder tries to identify chickadees in poor light on a winter's afternoon in the Poconos.
