Sartre: Life and Main Philosophical Ideas

Biographical Background

Jean-Paul Sartre lived from 1905 to 1980. He was a French philosopher, novelist, playwright, and public intellectual. Educated in Paris, he became the best-known representative of existentialism. His lifelong intellectual and personal partner was Simone de Beauvoir. After World War II, Sartre became deeply involved in leftist politics and anti-colonial causes.

His major philosophical works include Being and Nothingness, Existentialism Is a Humanism, and Critique of Dialectical Reason. His literary works include Nausea and No Exit.

Philosophical Thought

Sartre's central claim is that existence precedes essence. Human beings are not created according to a fixed design. We first exist, and then define ourselves through choices and actions.

This means that human beings are condemned to be free. We cannot avoid choosing. Even refusing to choose is a choice. Circumstances may limit us, but they do not remove responsibility for how we respond.

Freedom produces anguish because no external authority can choose for us. When we choose, we also express an image of what we think a human being should be. Choice therefore carries responsibility beyond private preference.

Sartre analyzes bad faith as the attempt to flee freedom by treating oneself as a fixed thing. A waiter who over-identifies with his role, or a person who says "I cannot help it; this is just what I am," hides freedom behind facticity. Human existence is a tension between facticity and transcendence.

Being and Nothingness distinguishes being-in-itself and being-for-itself. The in-itself is the being of things: full and self-identical. The for-itself is consciousness, marked by negation and possibility.

Sartre's account of others is often conflictual. The look of the other objectifies me and makes me aware of myself as seen. "Hell is other people" expresses this danger of objectification, not a simple rejection of human relations.

Sartre's importance lies in making freedom, responsibility, anguish, self-deception, and self-creation central themes of twentieth-century philosophy and literature.
