Existentialism and Radical Choice
What is existentialist philosophy, and how do you use Sartre’s ideas in practice?
Jean-Paul Sartre’s existentialism holds that human beings have no fixed nature — "existence precedes essence" — and are therefore radically free to define themselves through their choices. The practical implication is that you cannot hide behind role, instinct, or circumstance: you are always already choosing, including when you tell yourself you have no choice. This is philosophical rather than clinical; its overlap with ACT and CBT is real but indirect.
Sartre argued that the anxiety of being human is the anxiety of freedom: there is no script, no essence, no pre-given nature that tells you what to do. You are what you do, and every inaction is itself a choice. That is either liberating or vertiginous depending on how you hold it — the existentialist practices below are about learning to hold it as liberation rather than paralysis. These are philosophical practices, not therapeutic protocols; the evidence is where the mechanism has psychological grounding, and honest about where it does not.
Practices
- Take seriously that you have no fixed nature
- Spot bad faith in yourself
- Take radical responsibility for your choices
- Choose authentically — from your own values, not from expectation
- Sit with the anxiety of freedom
- Define yourself by actions, not intentions
Take seriously that you have no fixed nature
Stop treating your personality, role, or past as a given — you are always in the process of defining yourself.
Spot bad faith in yourself
Notice when you are treating yourself as a thing determined by role, instinct, or expectation — and claim the choice.
Take radical responsibility for your choices
Own every choice completely — including its unintended consequences and the unchosen conditions within which you chose.
Choose authentically — from your own values, not from expectation
Make choices that reflect your actual values rather than the role others have assigned you.
Sit with the anxiety of freedom
When the weight of choice produces vertigo, use it as a signal — not a problem to escape.
Define yourself by actions, not intentions
You are not your intentions or your self-image — you are the accumulation of what you actually do.
