A ressonância ética da negação em Sartre (considerações sobre liberdade, angústia evalores em L’être et le néant)

From the brief characterization of the figures of freedom, anguish and responsability, exposed in Jean Paul Sartre's L'être et le néant, this article aims to shed lights over the statement of the lack of foundation of the values adopted in our quotidian morality - that demans an explication of a certain ethical ressonance of the negation on the sartrean philosophy, as well the consequential human temptation to the existencial forgery, which manifests in its attempt to elide the anguish coming from the absolut freedom of the human reality.
