A transformative vision for human-animal relations on personal, social, and environmental levels. The Three Ethologies offers a fresh, affirmative vision for rebuilding human-animal relations. Venturing beyond the usual scholarly and activist emphasis on restricting harm, Matthew Calarco develops a new philosophy for understanding animal behavior—a practice known as ethology—through three distinct but interrelated lenses: mental ethology, which rebuilds individual subjectivity; social ethology, which rethinks our communal relations; and environmental ethology, which reconfigures our relationship to the land we co-inhabit with our animal kin. Drawing on developments in philosophy, (eco)feminist theory, critical geography, Indigenous studies, and the environmental humanities, Calarco casts an inspiring vision of how ethological living can help us to reimagine our ideas about goodness, truth, and beauty.
