"Brett Buchanan's Onto-Ethologies, which takes on the crucial task of elucidating the philosophical import of some Uexküllian concepts and tracking their fate in the work of three major later philosophers, is … both welcome and long overdue." — Symposium"…this is a subtle book, a welcome engagement with a renewed focus on certain strands of biophilosophies of the twentieth century, with a particular focus on animals at a time when the so-called 'animal question' is moving through a whole ream of different disciplines." — Radical Philosophy"Most interesting, perhaps, is Buchanan's conscious attempt to bridge continental philosophy with the sciences … This book will likely prove exciting for those interested in the environmental thinking of Heidegger, Merleau-Ponty, and Deleuze." — Environmental Philosophy
