Truth-telling, promises and the shape of a character

In this article I want to focus on a specific function that promises fulfil in our lives: their role as a way of shaping our character. To make my case, I will present an account of truth-telling based on Bernard Williams’ work on genealogy and on the virtues of truth. This account will highlight how our selves (or characters) are not static entities in time, that they are not immediately transparent to us. Nonetheless, we seem to have what I call a drive to be someone, to have a character. We need ways to ‘steady the mind’, that is, ways of shaping our selves to whom we are or want to be. The argument I will put forward is that promises are one of the resources we have for doing so. By making promises, we commit ourselves to acting in a certain way and by doing that we also shape our selves. The argument will help us to answer some philosophical challenges raised against promises, notably about their rationality and about their relationship with vows and resolutions. Additionally, it will impact our thinking about contract law. What emerges from this article is an account of an important role played by promises that has been often neglected by the literature.
