Central to the work of Roberto Marchesini is a sustained critical engagement with the sciences of animal behavior. Drawing on veterinary, biological, and philosophical training, he critiques the legacy of Cartesianism that sees animals as machines at the same time as acknowledging the importance of biological knowledge and approaches for understanding animals. Further, he offers his own version of a zooanthropological and posthumanist method for the future of ethology as an interdisciplinary social science founded on shared existence, interaction, and understanding. (...) His reframing of questions around biological and cultural continuity in turn refigures received notions of identity, animality, and the origin of culture itself. (shrink)
