Ressentiment
Ressentiment is a philosophical and psychological term, usually translated as resentment or ressentiment, describing a persistent form of negative affect that arises when a person cannot act on their genuine impulses or achieve their goals. It entails inward hostility, envy, and a tendency to condemn or invert values rather than directly confronting the source of frustration.
The concept is most closely associated with Friedrich Nietzsche, who analyzes ressentiment in On the Genealogy
In Nietzschean and subsequent interpretive use, ressentiment is not merely anger but a long-term, value-creating sentiment
