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.

The Intellective Space explores the nature and limits of thought. It celebrates the poetic virtues of language and the creative imperfections of our animal minds while pleading for a renewal of the humanities that is grounded in a study of the sciences.

According to Laurent Dubreuil, we humans both say more than we think and think more than we say. Dubreuil’s particular interest is the intellective space, a space where thought and knowledge are performed and shared. For Dubreuil, the term “cognition” refers to the minimal level of our mental operations. But he suggests that for humans there is an excess of cognition due to our extensive processing necessary for verbal language, brain dynamics, and social contexts. In articulating the intellective, Dubreuil includes “the productive undoing of cognition.”

Dubreuil grants that cognitive operations take place and that protocols of experimental psychology, new techniques of neuroimagery, and mathematical or computerized models provide access to a certain understanding of thought. But he argues that there is something in thinking that bypasses cognitive structures. Seeking to theorize with the sciences, the book’s first section develops the “intellective hypothesis” and points toward the potential journey of ideas going beyond cognition, after and before computation. The second part, “Animal Meditations,” pursues some of the consequences of this hypothesis with regard to the disparaged but enduring project of metaphysics, with its emphasis on categories such as reality, humanness, and the soul.
