Abstract
The idea of cooperation has been recently used with regard to human–animal relations to justify the application of an associative theory of justice to animals. In this paper, I discuss some of these proposals and seek to provide a reformulation of the idea of cooperation suitable to human–animal relations. The standard idea of cooperation, indeed, presupposes mental capacities that probably cannot be found in animals. I try to disentangle the idea of cooperation from other cognate notions and distinguish it from exploitation, use, and relationship. The upshot is a minimal taxonomy of human–animal relations that covers most possibilities, from the worst type of relation to that which is most favourable to animals’ welfare. In this taxonomy, cooperation is a form of relation where animals are used to produce a valuable good in a way that is compatible with their ethological features and without being harmed.
