In her recent book Ética y emoción (Plaza y Valdés), Mar Cabezas poses a central question of metathetics: how to justify our moral judgments. The author seeks a criterion that allows us to justify to others why we judge that something is morally good or bad, a criterion that allows us to start discussing such issues and looking for rules that guide our practices. Mar Cabezas argues that, if such a criterion is to be truly universal and serve as a basis for translation between different moral languages, it must necessarily take into account the emotions. It is the emotions, according to the author, that allow us to grasp the relevance of moral damage and (to some extent) make us susceptible to receiving it. Without them we would not be moral beings.
