Gary Varner is professor of philosophy at Texas A&M University. He wrote one of the first dissertations on environmental ethics, at the University of Wisconsin–Madison, and has since published two books and over 50 articles, book reviews, and encyclopedia entries on topics in environmental ethics and animal ethics. He is currently finishing a long-term project on animals and the moral philosophy of R.M. Hare. The first installment, Personhood, Ethics, and Animal Cognition: Situating Animals in Hare’s Two-Level Utilitarianism, was published by Oxford University Press in 2012. A second volume, tentatively titled Sustaining Animals: Envisioning Humane, Sustainable Communities, is in progress.
