Sartre's Existentialism Is a Humanism › The Weight of an Empty Sky

Imagine waking up tomorrow with a sudden, visceral realization: there is no cosmic plan for your life. No divine blueprint. No fate written in the stars. No human nature that determines what you must become. You are free. Radically, terrifyingly, exhilaratingly free. What do you do next? This is the question Jean-Paul Sartre forces upon us in his 1946 lecture *Existentialism Is a Humanism*. He delivered it to a packed room in Paris just months after the liberation of France. The lecture became one of the most influential philosophical texts of the twentieth century, because it made existentialism accessible, even though it introduced few new ideas to anyone willing to confront the consequences of genuine freedom. Sartre's message is simple to state and difficult to live: you are what you make of yourself, and you cannot blame anyone or anything else for who you become. There are no excuses. There is no escape from responsibility. This, Sartre insists, is not a counsel of despair but the only foundation for authentic human dignity.
