Agnes Callard discusses her recent book, The Agency of Becoming, which gives an account of aspiration–an account of what it is and how it is possible to become a better person in some specific respect (e.g. parenting, tennis-playing, music-appreciating). Callard begins with a paradox that any account of aspiration seems to face: the reasons someone has to become better in some specific respect are ones that are not available to her from the outset – they are only graspable once she has become what she has aspired to be – so, how can someone even aspire to be better in the first place? Callard argues that this paradox can in fact be avoided. This involves recognizing that certain entrenched views in decision theory and moral psychology are mistaken. Callard then turns to the final part of her book, which explains how it is that someone can be morally responsible for changes in her character. Callard flips the usual picture of such change on its head, arguing that we need to see a person's earlier self as bound to her later self through aspiring. At the close of the interview, Callard discusses two ongoing projects, one which criticizes the received view of value, and a second which argues that Socrates's main contribution to philosophy is an adversarial account of epistemology. Agnes Callard is Associate Professor of Philosophy at the University of Chicago.
