Abstract
This book seeks to undermine the widespread and tenacious idea that animal rights philosophies, being axiologically individualistic, are antithetical to the environmentalist agenda, commonly viewed as underwritten by a holistic meta-ethical framework. To this end, Varner defends a form of biocentric individualism, according to which all living organisms have interests, ones that generate prima facie entitlements, but which can be overridden in appropriate circumstances. He defends a sentientist principle that the lives of organisms with conscious desires have priority over those who lack the capacity for such desires, and a anthropocentric principle that gives priority to certain types of inclusive interests that only human beings have. He then argues that these principles are not only consistent with, but lend considerable support to, the environmentalist agenda.
