In this essay, I argue for a new analysis of Porphyry’s argument for justice in On abstinence. I aim to show that (i) in addition to being an inner order of soul, justice is attributed to external actions and (ii) justice of actions consists in refraining from harming harmless living creatures, including animals and plants. The relevant harm, I argue, consists in taking the lives of living creatures and taking products from them by force or without care. I contend that Porphyry extends moral concern for others to all living creatures, but not merely on the basis of animal suffering. Finally, I argue that that the hierarchy of godlikeness in On abstinence does not support the subordination of moral concern for animals and plants to higher virtues of purity and theory.
