Jean-Paul Sartre

French philosopher and writer Jean-Paul Sartre (1905–1980) explored freedom, responsibility, and existence across fiction, drama, criticism, and phenomenology. Nausea gives philosophical unease a concrete narrative form as Antoine Roquentin encounters objects stripped of familiar purpose. Being and Nothingness develops the conflicts of consciousness, bad faith, and relations with others at systematic scale. Sketch for a Theory of the Emotions asks how emotion reorganizes a situation rather than merely happening inside a passive mind. What Is Literature? turns from ontology to the ethical relation among writer, reader, history, and committed action, while Colonialism and Neocolonialism collects interventions whose political urgency also requires historical scrutiny. Nausea offers the strongest narrative entrance; What Is Literature? clarifies his account of writing, and Being and Nothingness demands close conceptual attention.
