This agenda-setting collection argues for the importance of fieldwork for philosophy and provides reflections on methods for such ‘field philosophy’ from the interdisciplinary vantage point of the environmental humanities. Field philosophy has emerged from multiple sources –including approaches focused on public and participatory research –and others focused on ethology, multispecies studies, and the environmental humanities more broadly. These approaches have yet to enter the mainstream of the discipline, however, and ‘field philosophy’ remains an open and uncharted terrain for philosophical pursuits. This book brings together leading and emerging philosophers who have engaged in critical and constructive forms of fieldwork, for some over decades, and who, through these articles, demonstrate new possibilities and new experiments for philosophical practices. This collection will be of interest to scholars working across the disciplines of continental philosophy, environmental humanities, science and technology studies, animal studies, cultural anthropology, art, and more. The chapters in this book were originally published as a special issue of Parallax.
