This paper is a discussion of the ‘moralization’ of resentment in Adam Smith’s Theory of Moral Sentiments. By moralization, I do not refer to the complex process by which resentment is transformed by the machinations of sympathy, but a prior change in how the ‘raw material’ of the emotion itself is presented. In just over fifty pages, not only Smith’s attitude toward the passion of resentment, but also his very conception of the term, appears to shift dramatically. What is an (...) unpleasant, unsocial and relatively amoral passion of anger in general metamorphoses into a morally and psychologically rich account of a cognitively sharpened, normatively laden attitude, an attitude that contains both the judgment that the injury done to me was unjust and wrongful, and the demand that the offender acknowledge its wrongfulness. Two very different readings of ‘Smithean resentment’ are thus available from the text. Indeed, the notion of two distinct forms of resentment – an instinctive, amoral version and a rich, rationally appraising attitude – would bring Smith into line with an earlier account of resentment, found in Bishop Joseph Butler’s Fifteen Sermons Preached at Rolls Chapel, first published in 1726. Ultimately, I argue, the differences in their theories are to Smith’s credit. It is precisely because the ‘thin’ or generic retaliatory passion described in Part I can be reconciled with the rich, normative attitude in Part II, that Smith is able to accomplish his meta-ethical goal of grounding moral judgments in naturally occurring emotions.
