Central to the social membership model of animal rights is the claim that relations with nonhuman animals should be reorganized such that domesticated animals are recognized as members of our shared societies. Though some elements of the membership model remain contested, the core of the membership model is that domesticated animals have a claim on, and a direct entitlement to, the benefits of cooperative relations. For many political theorists, however, distributive justice considerations apply only to a certain kind of cooperative (...) relationship. The community of justice recipients is thought to be limited by what Brian Berkey calls the Contribution/Capacity Basis of Entitlement. Accordingly, justice considerations apply to a scheme of cooperation and a conception of justice “entail[s] direct entitlements only for those who are contributors, or, alternatively, those who at least possess the capacities that are necessary to be capable of contributing to such a scheme”. This thesis – referred to as ‘contributionism’ – has typically been utilized to exclude nonhuman animals from justice considerations. The paper argues that contributionism is not fundamentally at odds with justice for domesticated animals, and conversely that contributionism remains a useful conceptual tool for explaining resource sharing with these nonhuman animals.
