Sartre’s Existentialism: A Guide to Freedom and Responsibility
Existentialism is a Humanism can feel like a rustic relic, yet it holds a radical key to unlocking your life’s purpose.
Though Jean-Paul Sartre is often overshadowed by his contemporaries like Heidegger and Derrida in upper-level academia, his 1945 lecture “Existentialism is a Humanism” remains a vital entry point into moral philosophy. It serves as a primer for a timeless confrontation with the human condition. By breaking Sartre’s dense philosophy into five digestible concepts, we uncover a blueprint for radical living.
The bedrock of Sartre’s thought is the concept that “existence precedes essence.” Unlike a designed tool, such as a paperknife, which is built with a specific purpose in mind, humans are born without a preordained plan or divine mandate. We exist first, and through our agency, we construct our own definition. This atheistic premise forces us to accept that we are entirely responsible for what we become; we are not following a script, but writing the original draft.
This leads directly to a terrifying and exhilarating reality: freedom. Because we lack a built-in nature, we are “condemned to be free.” There is no way to avoid choice. Even the decision to do nothing is a choice that builds the essence of who you are. We cannot blame circumstances or destiny; the slate is blank, and we are forced to fill it.
However, absolute freedom carries the heavy burden of absolute responsibility. This isn’t just about doing your chores; it is the existential liability of owning every action. As Sartre notes, this weight is why many people recoil from true freedom. Acknowledging that you are the author of your reality—and that your inactions contribute to the state of the world—requires brutal honesty.
Carrying this responsibility naturally creates “Anguish.” Unlike anxiety, which is often a vague worry, anguish is the distinct realization that in choosing for yourself, you are setting a standard for all humanity. You are effectively saying, “This is how a human being should act.” This realization is the cost of being a fully integrated, three-dimensional person.
The most common reaction to this discomfort is “Bad Faith.” To escape the heavy burden of freedom, people often hide behind rigid roles, monikers, or excuses—like the “I’m a good person” defense. By treating themselves as fixed objects rather than free agents, they dehumanize themselves to avoid the pain of choice. Sartre warns that while this offers temporary relief, it is a rejection of the authentic self.
Sartre’s insights are not merely academic; they are a practical toolkit for digital-age decision-making. We live in an era of algorithmic determinism and social pressure that constantly tries to define us. To embrace Existentialism is to reject these pre-coded essences. It reminds us that nothing is written in stone until we act. By accepting the weight of our choices, we reclaim the power to define our own meaning in a chaotic world.
