This paper offers a sustained philosophical meditation on contrasting interpretations of the emotion of shame within four academic discourses--social psychology, psychological anthropology, educational psychology and Aristotelian scholarship--in order to elicit their implications for moral education. It turns out that within each of these discourses there is a mainstream interpretation which emphasises shame's expendability or moral ugliness (and where shame is typically described as guilt's ugly sister), but also a heterodox interpretation which seeks to retrieve and defend shame. As the heterodox interpretation seems to offer a more realistic picture of shame's role in moral education, the provenance of the mainstream interpretation merits scrutiny. I argue that social scientific studies of the concept of shame, based on its supposed phenomenology, incorporate biases in favour of excessive, rather than medial, forms of the emotion. I suggest ways forward for more balanced analyses of the nature, moral justification and educative role of shame.
