For Aristotle a true friendship can only exist between free human beings, because true friendship is based on a shared understanding of the good. Yet today, some animal philosophers argue that friendships can exist between humans and animals, maybe not in Aristotle's sense of the word but in another way, that appreciates how animals are different from us humans, yet also share a certain commonality. Usually, these reflections on humananimal friendship concern human relations with domestic animals, notably pets. But can we befriend wild predators: those animals that by their very nature can be dangerous to us? In this paper, I examine what it might mean to befriend a wild animal, and whether it would be possible to be friends with wild wolves. I will argue that any friendly relation with wild animals will consists of a paradoxical combination of benevolent involvement and loving detachment. 1. Friendships between humans and animals Many people today are convinced that friendships between people and animals are possible. That thought is relatively new, especially in philosophy. According to Aristotle, true friendship can only exist between two free citizens, because according to him friendship consists of a conscious form of mutual benevolence. 1 Aristotle distinguishes three kinds of friendship: friendship is based on mutual benefit, or friendship is based on the pleasure that friends derive from being in each other's company, but in friendships of the third kind, true friendship, mutual benefit and enjoyment go together with a third factor, namely a mutual admiration for the moral qualities of the other. Real friends wish each other the best because they see the other for what they are. And since only humans have the ability to recognize moral virtues in one another, for Aristotle a true friendship can only exist between free people. Yet today, some animal philosophers argue that friendships do exist between humans and animals, maybe not in the true sense of the word but in a weaker version. 2 It is indeed difficult to deny 1 Friendship with a slave is impossible, according to Aristotle, insofar as he is a slave. 'Qua slave one cannot be friends with him; but qua man one can.' (Nicomachean Ethics, 1161 b5). 2 For example, see the article 'Animal Ethics Based on Friendship' by Barbro Fröding and Martin Peterson in the first issue of the Journal of Animal Ethics (Fröding and Peterson 2011). Fröding and Peterson believe that recognition of the mutual benefits that pets and their owners from each other is enough to base a friendship on.
