Essays in existentialism

Jean-Paul Sartre
≈ From memory

Existence precedes essence: humans are radically free beings who must create their own meaning through action in a universe that offers no inherent purpose.

Find the book

In one sentence

Human beings are not born with a predefined purpose or "nature"; instead, we appear on the scene, exist, and only afterward define who we are through the continuous series of choices we make.

Why read this (and who it's for)

This book is the foundational manifesto for a life of radical responsibility. It solves the paralysis of "finding yourself" by arguing that there is no "self" to find—only a self to create. It is for anyone who feels overwhelmed by the weight of choice, anyone seeking to understand the source of human anxiety, and anyone who wants a rigorous philosophical framework for personal agency and moral responsibility. After reading, you will be able to identify "Bad Faith" in your own excuses and recognize your own agency in every situation you deem "impossible."

The big idea

Sartre argues against the traditional Western philosophical tradition that assumes humans have an "essence"—a blueprint, a soul, or a biological destiny—that determines who they are. For a letter opener, the "essence" (to cut paper) precedes its physical existence. For a human being, however, the process is reversed: we exist first, we encounter the world, and only through our actions do we acquire a definition.

This leads to the terrifying and liberating conclusion of Radice Freedom. Because there is no God to conceive of us and no "Human Nature" to dictate our behavior, we are "condemned to be free." We are entirely responsible for what we do, what we choose not to do, and what we allow ourselves to become. Every action is a vote for what a human being ought to be.

The logic follows that if there is no pre-determined meaning, then meaning is not something we discover (like a hidden treasure); it is something we project (like a building). This makes the individual the sole architect of their values. While this creates "Anguish" (the realization of our total responsibility), it is the only way to live authentically.

Key ideas

Existence precedes essence

What it is — The core ontological claim that humans appear in the world without a prior blueprint. We are the only beings who can define ourselves through our actions. Why it matters — It destroys the excuse of "that's just the way I am." You are not your personality, your past, or your genes; you are the sum of your choices. In the book — Sartre contrasts the manufacture of a tool (which has a purpose before it is made) with the birth of a human (who has no purpose until they act).

Facticity vs. Transcendence

What it is — "Facticity" is the brute facts of your life (your birthplace, your body, your past). "Transcendence" is your conscious ability to project yourself beyond those facts. Why it matters — You are never just your facts (e.g., "I am a waiter"), but you are also not purely a spirit (e.g., "I am a free soul"). You are the tension between the two. In the book — Sartre explains that while you cannot choose your parents, you do choose what those parents mean to you and how you respond to them.

Bad Faith (Mauvaise Foi)

What it is — The act of lying to oneself to escape the overwhelming weight of freedom. It is pretending you are an object (a thing) with no choice, rather than a free consciousness. Why it matters — It is the root of most human excuses: "I had no choice," "That's just my job," or "I'm just a naturally angry person." In the book — The famous example of the waiter who plays at being a waiter—moving with too much precision, being too "waiter-like"—to convince himself he is a waiter by nature, rather than a free man performing a role.

The Look (Le Regard)

What it is — The moment you realize you are being watched by another person, you become aware of yourself as an "object" in their world. Why it matters — Our identity is often shaped by how others perceive us. The "Look" turns us into a thing to be judged, which is the source of shame. In the book — Sartre describes a man sitting alone in a cafe who realizes someone is watching him. Suddenly, he is no longer a subject experiencing the world; he is an object in someone else's experience.

Anguish (Angoisse)

What it is — The vertigo of freedom. It is the realization that nothing—not even your past—forces you to act in a certain way. Why it matters — Anguish is not a pathology; it is the honest recognition of your own power. To live without anguish is to live in a state of self-deception. In the book — Sartre describes the feeling of standing on a cliff and realizing not just that you might fall, but that you could throw yourself off. That "could" is the source of anguish.

Frameworks & tools

The Anatomy of Bad Faith

Use this to identify when you are hiding from your own freedom.

  1. Identify the "Given": Note the situation where you say, "I have no choice." (e.g., "I have to work this job I hate.")
  2. Identify the "Role": Determine what "character" you are playing to justify the situation. (e.g., "I'm just a loyal employee.")
  3. Analyze the Transcendence: Ask: "In what ways am I actually choosing to stay in this role?" (e.g., "I am choosing not to look for a new job because I fear the unknown.")
  4. Reclaim the Choice: Acknowledge that while the fact of the job is fixed, the meaning you give to it is your responsibility.

A checklist to ensure you are living authentically rather than in "Bad Faith."

Memorable examples & stories

The Waiter in the Cafe

Sartre describes a waiter whose movements are slightly too stylized, whose personality is too "waiter-ish." He is performing a role to escape the burden of being a free human. Lesson: We often perform roles to pretend we aren't responsible for our own lives.

The Man on the Cliff

The man looks down and feels a sense of vertigo. He realizes that his body is capable of throwing itself off the edge. Lesson: Freedom is not just about what we do; it is the terrifying realization of what we could do.

The Object vs. The Subject

Sartre describes how we experience the world as "subjects" (the ones doing the looking) until someone else looks at us, turning us into "objects" (the things being looked at). Lesson: Our self-consciousness is often a reaction to the gaze of others.

Key quotes

"Existence precedes essence." The fundamental rule of existentialism: you are born as a blank slate and define yourself through action.

"Man is condemned to be free; because once he is thrown into the world, he is responsible for everything he does." Freedom is not a gift; it is an inescapable burden of responsibility.

"I am my own project." (Paraphrased) You are not a finished product; you are a continuous process of becoming.

Common pitfalls

Connects to

If you remember only three things

Internalize it

Q: What is "Bad Faith" (Mauvaise Foi)? A: The act of deceiving oneself into believing one lacks freedom by pretending to be an object (a thing) with a fixed nature.

Q: What is the difference between Facticity and Transcendence? A: Facticity is the brute facts of your life (past, body, etc.); Transcendence is your conscious ability to project yourself beyond those facts.

Q: Why does Sartre say we are "condemned" to be free? A: Because we did not create ourselves, yet we are entirely responsible for every action we take once we are in the world.

Q: What is "The Look" (Le Regard)? A: The moment we become aware of ourselves as an object in the world of another person's perception.

Fidelity note

This summary is grounded in Sartre's core ontological and ethical arguments as presented in Existentialism is a Humanism and Being and Nothingness (the latter of which contains the foundational theories for the "Essays"). I am highly confident in the definitions of Bad Faith, Facticity, and Existence preceding Essence. I have paraphrased the "Waiter" and "Cliff" examples as they are standard pedagogical tools used to explain his complex phenomenological concepts. Readers should verify the specific nuances of "The Look" in Being and Nothingness for a deeper technical dive.
