This article explores the concept of syngnōmē in Aristotle’s ethics, especially in relation to the concept of forgiveness. The aim of this article is to understand the space the concept of forgiveness takes and its relationship to the other elements in his ethical system, using syngnōmē as a clue for investigation. First, this article addresses how syngnōmē demonstrates the so-called Aristotelian particularism. Then this article discusses the concept of epieikeia, which is the excellence of the person who has syngnōmē. In particular, the problem of how to understand the fact that Aristotle’s discussion of the concept appears to contain two different elements is addressed. In the final section, some philosophical questions concerning understanding syngnōmē as forgiveness and sympathy are considered.
