Organism and Environment can best be described as a philosophical interpretation of recent developments in the life sciences. Using insights from postmodern philosophers, especially Gadamer, Winslow (philosophy, St, John's College) highlights the ontological prejudices behind discourses in evolutionary biology. He uncovers a particular assumption, that of the autonomous, individually existing subject at the heart of the familiar theory of adaptation by (vertical) genetic inheritance from parent to offspring. This "humanist" prejudice, or, to use Heidegger's term, "metaphysics of presence," is now giving way to an ecological ontology consisting of horizontal modes of genetic inheritance that render the humanist individual no longer feasible. This book is useful as an insightful application of hermeneutics, but it will also help those in the philosophy of biology reflect further on developments in their field…. Summing Up: Recommended. Graduate students, researchers, faculty.
