 Starting from the absence of God, the key theme of Nuptials, and the inevitability of absurdity, the key theme of The Myth of Sisyphus, Camus incorporates both of these into The Rebel, but alongside them he now stresses revolt. The act of rebellion assumes the status of a primary datum of human experience, like the Cartesian cogito taken by Sartre as his point of departure. Camus first expressed this directly under the inspiration of his encounter with Being and Nothingness. But in calling it “revolt” he takes it in a direction sharply different from Sartre, who built from the cogito an “essay in phenomenological ontology.” Ignoring completely the ontological dimension, Camus is now concerned with immediate issues of human social experience. Revolt, to be sure, still includes the rebellion against absurdity that Camus described in The Myth of Sisyphus, and once again he will speak of rebelling against our own mortality and the universe’s meaninglessness and incoherence. But The Rebel begins with the kind of revolt that rejects oppression and slavery, and protests against the world’s injustice.
