Here’s the single most important thing to understand before you write a single sentence: a philosophy essay is not a report of your opinions, and it is not a descriptive summary of what a philosopher said. It is an argument.
As Jim Pryor’s widely used writing guidelines explain, “Your paper must offer an argument. It can’t consist in the mere report of your opinions, nor in a mere report of the opinions of the philosophers we discuss. You have to defend the claims you make.” [1] You need reasons for everything you assert. You need to present those reasons clearly enough that a reader who disagrees with you can follow your logic.
This means philosophy essays share more DNA with a courtroom argument than with a creative writing assignment. You’re presenting a case, building evidence, and anticipating the opposition’s best counterarguments.
What Your Marker Is Actually Grading
- How well you understand the philosophical issue
- How good your own arguments are
- How clear and well-organized your writing is
You won’t lose marks for having a controversial conclusion. You will lose marks for not arguing clearly.
The Four-Part Structure
Every solid philosophy essay follows a recognizable structure. While the exact proportions vary by topic and word limit, the core moves are consistent across virtually all university philosophy departments.
1. Introduction (roughly 10% of word count)
Your introduction has three essential jobs. It needs to:
- Introduce the problem — Explain what philosophical issue the essay addresses and why it’s worth discussing
- State your thesis clearly — “In this essay, I will argue that…” not “I think that…” or vague hedging
- Provide a roadmap — Tell the reader exactly what sections follow and what you’ll do in each one
Peter Lipton from Cambridge’s Department of History and Philosophy of Science puts it bluntly: “Replace sentences like ‘Throughout the centuries, the greatest minds have pondered the intractable problem of free will’ with ‘In this essay, I will show that free will is impossible.'” [2] The Cambridge guide adds that your introduction should give the reader “a clear map of the essay.”
2. Exposition and Body (roughly 60-70%)
This is the main body of your essay. But unlike a research paper, a philosophy essay’s body isn’t just “the body.” It has distinct sub-sections, each with a clear purpose.
What goes in the exposition section:
- A fair, accurate account of the position or philosopher you’re discussing
- The key arguments they make, reconstructed in your own words
- No straw-man versions. As Cambridge’s guide instructs, you should always “take the position in its strongest form”
What goes in your argumentation section:
- Your own premises leading to your conclusion
- Clear definitions of key terms
- Concrete examples that illustrate your reasoning
The University of Melbourne’s philosophy essay guide emphasizes that your essay must perform two functions: exposition and critical discussion. [3] These “can, but need not always, correspond to physically or structurally distinct sections.” However, for clarity — especially in shorter undergraduate essays — keeping them distinct is the safest strategy.
3. Objections and Replies (roughly 15-20%)
This is where most students lose marks. They jump straight to defending their own thesis without ever engaging the strongest possible objection.
The principle of charity, explained
The principle of charity is one of the most important (and hardest) rules in philosophical writing. It means:
- Never attack a weak version of an opponent’s argument
- Always reconstruct their position in its strongest, most defensible form
- Only then try to refute it
Cambridge’s writing guide puts it this way: “If you can’t see anything the view you’re criticizing has going for it, maybe that’s because you haven’t yet fully understood why its proponents are attracted to it. Try harder.” [2]
Jim Pryor’s guidelines expand on this: “Don’t treat the philosopher as stupid. If the view seems obviously crazy, think hard about whether he really does say what you think he says.”
4. Conclusion
Your conclusion has three jobs:
- Restate your thesis in past tense (“In this essay, I argued that…”)
- Summarize the main steps of your argument
- Note the significance — why does your conclusion matter?
Crucially, your conclusion must not introduce any new information. Cambridge’s guide states that the conclusion “should remind the reader how the different moves in the body of the essay fit together to form a coherent argument.” [2]
Discipline-Specific Examples
Ethics Essay Example
Topic: “Is artificial contraception morally permissible?”
Structure:
- Introduction: State the ethical framework you’re working within (e.g., natural law theory vs. consequentialism)
- Exposition: Explain the natural law argument against contraception (e.g., the Catholic tradition’s reasoning)
- Your argument: Present a consequentialist objection — if the consequences of contraception are neutral or beneficial, the natural law argument fails
- Objections: “But what about the intrinsic meaning of the bodily act?” (Acknowledge and respond)
- Conclusion: Summarize your reasoning
Philosophy of Mind Essay Example
Topic: “Can machines think?”
Structure:
- Introduction: Frame the Turing Test question — “What counts as thinking?”
- Exposition: Explain the functionalist position (thought is defined by function, not substance)
- Your argument: Present Searle’s Chinese Room as a counter-argument, then respond with a refinement of functionalism
- Objections: “But consciousness isn’t just computation.” (Engage the hard problem directly)
- Conclusion: What your discussion reveals about the limits of current AI theory
Common Mistakes (And How to Avoid Them)
Mistake 1: Writing a descriptive essay instead of an argumentative one
Your marker knows the readings. They’re not asking you to summarize Hume. They’re asking whether you can evaluate his argument and present your own response.
Fix: Every paragraph should advance a claim, not just report what a philosopher said. After describing a position, always add your own reasoning.
Mistake 2: Attacking a straw-man version
If your opponent’s argument seems too weak to refute, you probably didn’t understand it well enough. Weak arguments aren’t interesting enough to write about.
Fix: Always reconstruct the opposing position in its strongest form before criticizing it. Ask yourself: “What would a smart, thoughtful advocate of this position say?”
Mistake 3: Ignoring word limits
The University of Melbourne guide notes that “essays which are basically first draft rush-jobs done the night before they are due” tend to be weak, and that essays going well over the limit are “often due to unstructured waffle or padding.” [3]
Fix: Plan your sections before you write. Allocate word counts to each section. Cut anything that doesn’t directly serve your central argument.
Mistake 4: Obscure writing
Cambridge’s department warns: “Obscurity is not a sign of profundity. Some profound thought may well be difficult to follow, but that doesn’t mean that one can achieve profundity merely through producing obscure, difficult-to-read writing.” [2]
Fix: Use simple, straightforward prose. Write clearly enough that a third-grade audience could understand your argument (as Jim Pryor recommends). If you wouldn’t say it in conversation, don’t write it. [1]
Planning Your Essay: The Outline Strategy
Philosophy departments are almost unanimous on one point: you cannot write a good philosophy essay without a detailed outline first.
Jim Pryor estimates that “making an outline is at least 80% of the work of writing a good philosophy paper.” [1] The University of Melbourne agrees: “Poor essay structure is one of the most common weaknesses in student philosophy essays.”
What We Recommend
Here’s what I’d tell every student who asks how to write a philosophy essay:
- Start with the question, not the answer. Spend time understanding the problem your essay topic addresses before forming your thesis.
- Make the structure obvious. Use signpost words (“I will now argue,” “This objection fails because,” “My second premise is”) so your reader never gets lost.
- Engage the strongest objection. If your thesis is defensible, there will be a smart, serious objection to it. Find that objection. Address it. Your essay grade depends on it.
- Write for clarity, not impressiveness. If your prose sounds like a third-grade reading level, you’re on the right track.
- Revise at least three times. Read your draft out loud. Show it to a friend. If they can’t answer in one sentence what your main argument is, your argument is buried.
