A primatologist and a humanist together explore the meaning of being a “human animal” Humanness is typically defined by our capacity for language and abstract thinking. Yet decades of research led by the primatologist Sue Savage-Rumbaugh has shown that chimpanzees and bonobos can acquire human language through signing and technology. Drawing on this research, Dialogues of the Human Ape brings Savage-Rumbaugh into conversation with the philosopher Laurent Dubreuil to explore the theoretical and practical dimensions of what being a “human animal” means. In their use of dialogue as the primary mode of philosophical and scientific inquiry, the authors transcend the rigidity of scientific and humanist discourses, offering a powerful model for the dissemination of speculative hypotheses and open-ended debates grounded in scientific research. Arguing that being human is an epigenetically driven process rather than a fixed characteristic rooted in genetics or culture, this book suggests that while humanness may not be possible in every species, it can emerge in certain supposedly nonhuman species. Moving beyond irrational critiques of ape consciousness that are motivated by arrogant, anthropocentric views, Dialogues on the Human Ape instead takes seriously the continuities between the ape mind and the human mind, addressing why language matters to consciousness, free will, and the formation of the “human animal” self.

“Is the tick a machine or a machine operator? Is it a mere object or a subject?” With these questions, the pioneering biophilosopher Jakob von Uexküll embarks on a remarkable exploration of the unique social and physical environments that individual animal species, as well as individuals within species, build and inhabit. This concept of the umwelt has become enormously important within posthumanist philosophy, influencing such figures as Heidegger, Merleau-Ponty, Deleuze and Guattari, and, most recently, Giorgio Agamben, who has called Uexküll “a high point of modern antihumanism.” A key document in the genealogy of posthumanist thought, A Foray into the Worlds of Animals and Humans advances Uexküll’s revolutionary belief that nonhuman perceptions must be accounted for in any biology worth its name; it also contains his arguments against natural selection as an adequate explanation for the present orientation of a species’ morphology and behavior. A Theory of Meaning extends his thinking on the umwelt, while also identifying an overarching and perceptible unity in nature. Those coming to Uexküll’s work for the first time will find that his concept of the umwelt holds new possibilities for the terms of animality, life, and the framework of biopolitics.

Reflecting upon the changing human condition, Palsson addresses various conflated zones of life at particular times and scales. Engaging with topical issues on the public agenda, from personal genomics to human-animal relations to the global environment, the book sets out a compelling case for meaningful change.

Collected essays by a leading philosopher situating the question of the animal in the broader context of a relational ontology There is a revolution under way in our thinking about animals and, indeed, life in general, particularly in the West. The very words man, animal, and life have turned into flimsy conceptual husks—impediments to thinking about the issues in which they are embroiled. David Wood was a founding member of the early 1970s Oxford Group of philosophers promoting animal rights; he also directed Ecology Action (UK). Thinking Plant Animal Human is the first collection of this major philosopher’s influential essays on “animals,” bringing together his many discussions of nonhuman life, including the classic “Thinking with Cats.” Exploring our connections with cats, goats, and sand crabs, Thinking Plant Animal Human introduces the idea of “kinnibalism” (the eating of mammals is eating our own kin), reflects on the idea of homo sapiens, and explores the place of animals both in art and in children’s stories. Finally, and with a special focus on trees, the book delves into remarkable contemporary efforts to rescue plants from philosophical neglect and to rethink and reevaluate their status. Repeatedly bubbling to the surface is the remarkable strangeness of other forms of life, a strangeness that extends to the human. Wood shows that the best way of resisting simplistic classification is to attend to our manifold relationships with other living beings. It is not anthropocentric to focus on such relationships; they cast light in complex ways on the living communities of which we are part, and exploring them recoils profoundly on our understanding of ourselves.

To care can feel good, or it can feel bad. It can do good, it can oppress. But what is care? A moral obligation? A burden? A joy? Is it only human? In Matters of Care, María Puig de la Bellacasa presents a powerful challenge to conventional notions of care, exploring its significance as an ethical and political obligation for thinking in the more than human worlds of technoscience and naturecultures. Matters of Care contests the view that care is something only humans do, and argues for extending to non-humans the consideration of agencies and communities that make the living web of care by considering how care circulates in the natural world. The first of the book’s two parts, “Knowledge Politics,” defines the motivations for expanding the ethico-political meanings of care, focusing on discussions in science and technology that engage with sociotechnical assemblages and objects as lively, politically charged “things.” The second part, “Speculative Ethics in Antiecological Times,” considers everyday ecologies of sustaining and perpetuating life for their potential to transform our entrenched relations to natural worlds as “resources.” From the ethics and politics of care to experiential research on care to feminist science and technology studies, Matters of Care is a singular contribution to an emerging interdisciplinary debate that expands agency beyond the human to ask how our understandings of care must shift if we broaden the world.

Gregory F. Tague’s An Ape Ethic and the Question of Personhood argues that great apes are moral individuals because they engage in a land ethic as ecosystem engineers to generate ecologically sustainable biomes for themselves and other species. Tague shows that we need to recognize apes as eco-engineers in order to save them and their habitats, and that in so doing, we will ultimately save earth’s biosphere. The book draws on extensive empirical research from the ecology and behavior of great apes and synthesizes past and current understanding of the similarities in cognition, social behavior, and culture found in apes. Importantly, this book proposes that differences between humans and apes provide the foundation for the call to recognize forest personhood in the great apes. While all ape species are alike in terms of cognition, intelligence, and behaviors, there is a vital contrast: unlike humans, great apes are efficient ecological engineers. Therefore, simian forest sovereignty is critical to conservation efforts in controlling global warming, and apes should be granted dominion over their tropical forests. Weaving together philosophy, biology, socioecology, and elements from eco-psychology, this book provides a glimmer of hope for future acknowledgment of the inherent ethic that ape species embody in their eco-centered existence on this planet.

Ambitious and elegant, this book builds a bridge between evolutionary theory and cultural psychology. Michael Tomasello is one of the very few people to have done systematic research on the cognitive capacities of both nonhuman primates and human children. The Cultural Origins of Human Cognition identifies what the differences are, and suggests where they might have come from. Tomasello argues that the roots of the human capacity for symbol-based culture, and the kind of psychological development that takes place within it, are based in a cluster of uniquely human cognitive capacities that emerge early in human ontogeny. These include capacities for sharing attention with other persons; for understanding that others have intentions of their own; and for imitating, not just what someone else does, but what someone else has intended to do. In his discussions of language, symbolic representation, and cognitive development, Tomasello describes with authority and ingenuity the "ratchet effect" of these capacities working over evolutionary and historical time to create the kind of cultural artifacts and settings within which each new generation of children develops. He also proposes a novel hypothesis, based on processes of social cognition and cultural evolution, about what makes the cognitive representations of humans different from those of other primates. Lucid, erudite, and passionate, The Cultural Origins of Human Cognition will be essential reading for developmental psychology, animal behavior, and cultural psychology.
