abstract Contractarianism roots moral standing in an agreement among rational agents in the circumstances of justice. Critics have argued that the theory must exclude nonhuman animals from the protection of justice. I argue that contractarianism can consistently accommodate the notion that nonhuman animals are owed direct moral consideration. They can acquire their moral status indirectly, but their claims to justice can be as stringent as those among able‐bodied rational adult humans. Any remaining criticisms of contractarianism likely rest on a disputable (...) moral realism; contractarianism can underwrite the direct moral considerability of nonhuman animals by appealing to a projectivist quasi‐realism.

In this essay I describe how contractarianism might approach interspecies welfare conflicts. I start by discussing a contractarian account of the moral status of nonhuman animals. I argue that contractors can agree to norms that would acknowledge the “moral standing” of some animals. I then discuss how the norms emerging from contractarian agreement might constrain any comparison of welfare between humans and animals. Contractarian agreement is likely to express some partiality to humans in a way that discounts the welfare of (...) some or all animals. While the norms emerging from the contract might be silent or inconsistent in some tragic or catastrophic cases, in most ordinary conflicts of welfare, contractors will agree to norms that produce some determinate resolution. What the agreement says can evolve depending upon how the contractors or the circumstances change. I close with some remarks on contractarian indeterminacy. (shrink)
