Carlos Thiebaut and Antonio Gómez Ramos link a dialogue, through an alternate series of chapters, about the complex emotion of resentment within a socio-political context and within the framework of reflections about justice, harm, memory or forgiveness . As an affection, resentment has not enjoyed the favor of psychologists, let alone those who deal with morality. However, beyond the psychological field, resentment is an emotion that is related to the political and social spaces, in which it intervenes and is configured. Indeed, the peculiar structure of resentment-its relational and reflexive character, its practical, moral and political tone-demands a differentiated attention beyond moral psychology. Social conflict and class differences, the trauma of the Holocaust, the experience of totalitarianism of the twentieth century and the transitions from dictatorship to democracy will be the themes of reference with which the authors will analyze resentment. The reasons for the bitterness do not seek answers or solutions, but a recognition of the role that this condition plays in the victims, in this way, to better understand the possible ways and limits of the elaboration of the damage.
