What Does "Existence Precedes Essence" Mean, and How Do You Teach It?

Quick answer"Existence precedes essence" is Sartre's claim that a human being first exists and only then defines themselves through action, unlike a manufactured object whose purpose is fixed before it is made. It does not deny bodily or social conditions. Teach it by contrasting a pair of scissors with a family's career plan, as Sartre and the Priority of Existence does in its first lesson.

Students meet the phrase in a textbook, nod, and then explain it as "you can become anything you want". That reading turns Sartre into a motivational poster and ignores everything he says about situation. Sartre and the Priority of Existence works through Existentialism Is a Humanism (lecture 1945, published 1946) with original paraphrases and four cases. You get a 32-page student book with four five-page sections, a concept page and two practice assessments, plus a 20-page teacher guide with timed 90-minute plans, expected answers for every task and a 100-point marking scheme. An editable Word edition is included.

The teaching problem

What the phrase actually claims

Start with the contrast Sartre himself uses in the lecture. A manufactured object is made according to a conception. Someone decides what a paper knife (in the unit, a pair of scissors) is for and how it should be built, and only then does the object exist. Its essence, meaning its purpose and defining nature, comes first. Sartre argues that human beings are different. In his atheistic account there is no creator whose plan fixes in advance what a human life is for. So a person exists first, meets the world, and defines themselves afterwards through what they actually do. Essence is not cancelled; it comes later and is never finished while the person is alive.

The second half of the claim is what students usually drop. Sartre does not say people have no bodies, no history or no social position. The unit's concept page calls these given conditions facticity, and the explanation is direct: the thesis concerns the absence of a predetermined purpose for a human life, not the denial of bodily properties or social conditions. Freedom here means having to take a position towards the possibilities your situation actually offers. A related term is the project, an orientation towards possibilities that only takes shape in action. That is why Sartre puts so much weight on decisions people live out rather than on how they describe themselves.

A worked example makes this concrete. Case M1 in the unit: scissors are designed for cutting, and a student's family wants her to enter a particular profession. A classmate says both cases are identical because the purpose is already fixed. Students turn Sartre's reply into two premises and a conclusion. Premise 1: an object made according to a prior conception has its purpose before it exists. Premise 2: no prior conception fixes what a human life is for. Conclusion: for humans, existence comes first and self-definition follows through action. The family's plan is a social demand, not a blueprint of her essence. It can still restrict her options, and that pressure deserves to be taken seriously.

A sequence that works

How to teach existence precedes essence in five steps

The steps follow the four sections of the student book and finish with a practice assessment that tests the common misreading.

  1. The manufactured object examplePages 3–7. Present the scissors and the family career plan without the worked answer. Students reconstruct the analogy, mark where Sartre would reject it and write the argument as two premises and a conclusion. Close on the debate question: does social pressure by itself refute Sartre's thesis?
  2. Self-projection and actionPages 8–12. Lea calls herself helpful but turns down three feasible opportunities without explanation. Omar wants to help but is caring for a relative. Neither takes part. Students build a matrix of intention, opportunity, decision and outcome to see why the same visible result does not mean the same responsibility.
  3. Choosing an image of humanityPages 13–17. A student copies an assignment and says it affects only her. Students trace the effects on assessment, trust and shared rules, then state Sartre's responsibility argument and an objection to its scope. Strong answers separate empirical consequences from Sartre's wider claim about all humanity.
  4. Humanism without a fixed essencePages 18–22. Students compare two readings: "Anyone can become anything if they want" and "People must take a position towards possibilities within their situation." They decide which fits Sartre better and write a corrected 100-word introduction for younger students, which shows quickly whether the distinction has landed.
  5. Practice assessmentSet Practice 1. A career guide tells students they are completely free and anyone who misses a goal chose wrongly, citing Sartre. A student points to money and family duties. Students reconstruct the claim, analyze it with existence, project and facticity, and judge it. Marking is out of 100.

Where it goes wrong

Misconceptions to plan for

These four misreadings come up in almost every class, and the unit has a case or task aimed at each one.

"Existence precedes essence means anyone can become anything." This confuses freedom with omnipotence. Sartre's point is that people must take a position towards the possibilities within their situation. The given conditions he calls facticity stay real. In the fourth section students compare this reading with the accurate one and explain what the first gets wrong.

"A family's career plan fixes her purpose just like a design fixes the purpose of scissors." Scissors have a manufacturing purpose. A family's expectations are a social demand, not a logical blueprint of who the person is. That does not make the pressure harmless: it can narrow real options, and the guide treats that as a fair point in the debate.

"If you fail to reach a goal, you chose wrongly." Sartre's claim does not mean every failure is self-inflicted. The teacher guide marks this as confusing responsibility with guaranteed success. Students separate intention, available action and outcome, and a strong answer can still ask whether Sartre gives enough weight to social conditions.

"A person is just whatever they say they are." Sartre puts the weight on lived decisions, not self-descriptions. Lea calls herself helpful but declines three opportunities she could have taken. Her description conflicts with what she does. Omar does not take part either, but his care work is itself a responsible action, so the two cases differ.

Primary text

Using Existentialism Is a Humanism alongside the unit

The unit uses original paraphrases, clearly labeled as such, rather than extracts from a published translation. That keeps the reading level manageable and avoids copyright problems, but it does not replace the primary text. The teacher guide lists the Yale edition and a historical English translation of the lecture as sources, and notes that close analysis of Sartre's own wording needs lawful access to an edition. A practical approach is to teach the first section from the student book, then give students the passage on the manufactured object from your own copy and ask them to check the paraphrase against it.

The comparison is useful in its own right. Students can look for what the paraphrase leaves out, where Sartre's wording is stronger or more hedged, and whether the scissors example changes anything compared with his paper knife. It is also worth showing them that the lecture was a defense of existentialism against accusations of despair and arbitrariness, which explains its tone. For a class working towards essays on existentialism, that short exercise in reading against a paraphrase is good practice for handling secondary summaries in general. It also shows you quickly who has understood the argument and who has only memorized the slogan.

Fair criticism

Teaching objections without straw men

Students enjoy attacking Sartre, and the most common attack is that he ignores poverty, illness or discrimination. That objection has force, and the unit takes it seriously: the fourth section ends on how responsibility can be understood without blaming disadvantaged people for every limitation. But the guide insists that fair criticism reconstructs the claim before naming its precise limitation. If a student argues against "you can become anything", they are arguing against a position Sartre does not hold. The unit's Lea and Omar case shows why: both fail to take part, yet only one of them is using a situation as an excuse, and students have to see that difference before their criticism lands.

A good routine is to require one sentence of reconstruction before every objection. The feedback pages help here. Instead of writing "reflect more" on a weak paragraph, you ask the student to write a countercase where their conclusion fails. Practice 2 gives them a clean target: a school assigns students permanently to career groups using a short personality test and claims it reveals each person's true essence. The expected answer separates the empirical validity of the test from its normative use, which is exactly the move the best critics of Sartre make.

Questions teachers ask

Frequently asked questions

Which courses does this topic and unit fit?

It suits Grades 11–12 philosophy, ethics and humanities electives that cover existentialism, freedom or personal identity. It roughly maps to A Level Philosophy (Years 12–13), Australian senior secondary philosophy courses (Years 11–12) and IB Diploma Philosophy. TeachLessons is not affiliated with or endorsed by the College Board, the IB, any exam board, ACARA or any state. The unit was originally developed for German upper-secondary courses, and the English edition is a full parallel version.

Who said "existence precedes essence"?

Jean-Paul Sartre, most famously in Existentialism Is a Humanism, a lecture given in Paris in 1945 and published in 1946. The formula sums up his atheistic existentialism: because there is no creator's plan for human nature, people exist first and define themselves through their actions. It is often quoted without that context, which is one reason students misread it.

What is the difference between essence and facticity?

Essence, in the unit's definition, is a fixed nature or defining conception, the kind of thing a design gives a pair of scissors. Facticity is the set of given conditions a person did not choose, such as body, family or social position. Sartre denies that humans have a prior essence, but he does not deny facticity. Freedom means responding to those conditions.

Does Sartre say social conditions do not matter?

No, and the unit is careful on this point. The explanation states that the thesis does not deny bodily properties or social conditions. What Sartre rejects is a predetermined purpose for a human life. Whether he gives social conditions enough weight is a fair question, and both the fourth section and the marking guidance treat it as a legitimate line of criticism.

How long does it take to teach?

The teacher guide plans four 90-minute core lessons, one per section, each with a minute-by-minute plan. Workshop and extension pages can take extra time. The jigsaw takes 45–60 minutes, and each practice assessment takes 90 minutes, or 135 for extended work. If you only want the core idea, the first section on its own covers the scissors example in one double lesson.

What files are included?

You get an instant digital download with a 32-page student book and a 20-page teacher guide as A4 PDFs, plus an editable Word text edition. The PDFs print on US Letter if you choose fit-to-page in the print dialog. The student book includes a concept page defining existence, essence, project and facticity, two practice assessments, a jigsaw, a portfolio page and a self-check.
