This article discusses some aspects of animal ethics from an Aristotelian virtue ethics point of view. Because the notion of friendship (philia) is central to Aristotle’s ethical theory, the focus of the article is whether humans and animals can be friends. It is argued that new empirical findings in cognitive ethology indicate that animals actually do fulfill the Aristotelian condition for friendship based on mutual advantage. The practical ethical implications of these findings are discussed, and it is argued that eating (...) meat from free-living animals is more morally acceptable than eating cattle because hunters (unlike farmers) do not befriend their prey.
