Can shame become a source of political strength? Faced with injustice, growing inequality and systemic violence, we cry out in shame. We feel ashamed of obscene wealth amid wider deprivation. We feel ashamed of humanity for its ruthless and relentless exploitation of the earth. We feel ashamed of the racism and sexism that permeate society and our everyday lives.This difficult emotion is not just sadness or a withdrawal into oneself, nor is it a paralysing sense of inadequacy. As Frédéric Gros argues in A Philosophy of Shame, it arises when our perception of reality rejects passivity and resignation and instead embraces imagination. Shame thus becomes the expression of an anger that is a powerful, transformative force -one that assumes a radical character.In dialogue with authors such as Primo Levi, Annie Ernaux, Virginie Despentes and James Baldwin, Gros explores a concept that is still little understood in its anthropological, moral, psychological and political depths. Shame is a revolutionary sentiment because it lies at the foundation of any path of subjective recognition, transformation and struggle.
