Abstract
Does the idea of justice make sense only in the human world? Can it make sense also in the world of non-human animals? Put another way, is there scope for justice in the animal world, or is it simply a “might is right” world? Starting from recent research of ethologists, philosophers, psychologists, and jurists, we will reflect on the hypothesis of the existence of an “animal justice” through the identification of three possible contexts of justice in the animal world (distributive justice, ludic fairness, retributive justice) and the analysis of a famous experiment on justice among monkeys. This research allows us to explore the axiological dimension of the hypothetical deontic world of non human animals.
