Existentialism: you're not born with a purpose — you build one

Most of us assume we arrive with a built-in purpose, like a knife made to cut. Existentialism flips this. Jean-Paul Sartre's famous slogan is "existence precedes essence" — meaning we first exist, show up in the world, and only afterward define who we are through the choices we make. There's no cosmic blueprint handed out at birth; a human is the one thing whose nature isn't fixed in advance.

That freedom sounds liberating, but Sartre argued it comes with a weight he called anguish. If nothing outside you dictates your values, then you are fully responsible for them — you can't blame human nature, God, or society for who you become. He even claimed we are "condemned to be free": we didn't ask for this freedom, yet we can't escape it.

To dodge that responsibility, people slip into what Sartre named bad faith — pretending our choices are forced. The waiter who acts only as "a waiter," or someone who says "I had no choice," is hiding from their freedom behind a role or an excuse. Existentialism's challenge is to instead live authentically: to own your choices as genuinely yours.

This is why existentialists insist meaning is made, not found. The universe offers no ready-made answer to "why am I here?" — but that emptiness is also an invitation to author your own reply.
