In this paper I discuss the notion of old times’ sake, one which is hardly discussed by moral philosophers, and claim that it serves as a moral reason for us to act on behalf of the people we used to cherish: former friends, colleagues, neighbors, or spouses. While our relationship with them has ended, the building-blocks of our identity will continue to bear their fingerprints, and they will ever be an important part of our biography. Acting for old times’ sake (...) reflects both our caring about them, and our caring about our own past, biography, and accumulated identity. Why the relationship has ceased will of course affect our attitude towards them. Although old times’ sake might not always be a decisive factor, it still serves as a moral reason for action. (shrink)
