You finished the readings. You worked through the arguments. You sat down and wrote what felt like a solid essay, only to get it back with a grade that didn’t reflect the effort you put in. Sound familiar?
Most philosophy students who lose points aren’t losing them because they don’t understand the material. They’re losing them because of specific, repeatable writing mistakes that are completely fixable once you know what to look for.
Let’s go through them one by one.
Mistake 1: Explaining a Philosopher’s View Instead of Engaging With It
This is probably the most widespread issue in undergraduate philosophy essays. A student reads Kant’s categorical imperative, writes a careful paragraph explaining what Kant said and what he meant, and then moves on.
Explaining a view tells your reader what a philosopher argued. Engaging with a view means doing something with that argument: evaluating whether it holds up, identifying a weakness in the reasoning, or connecting it to another position.
A good rule of thumb: for every philosopher’s view you introduce, you should have at least as much critical engagement as explanation. If your paragraph is 80% exposition and 20% analysis, flip the ratio. Philosophy instructors are mostly reading for evaluation, not summary.
Mistake 2: Straw-Manning the Opposing View
One of the most damaging moves in a philosophy essay is to misrepresent a position you’re arguing against — whether on purpose or by accident. When you set up a weaker version of an argument just to knock it down, it’s called straw-manning, and philosophy professors spot it immediately.
The real job is the opposite: find the strongest possible version of the view you’re challenging, and engage with that. If you can take down the best form of the argument, your own position becomes genuinely persuasive. If you can only defeat a weakened caricature of it, your argument hasn’t actually done much work.
In fact, demonstrating that you understand why a position is attractive, even one you disagree with, is one of the clearest signs of strong philosophical thinking.
Mistake 3: Using Key Terms Without Defining Them
Philosophy is built on precision. Words like “truth,” “freedom,” “justice,” “consciousness,” and “good” don’t have single, agreed-upon meanings, and in philosophy, that’s the whole point. Different philosophers mean different things by these terms, and your essay needs to be clear about which meaning you’re working with.
If you write “freedom is necessary for moral responsibility” without defining what you mean by freedom, you haven’t really said anything yet. Compatibilists and libertarians disagree on exactly this point. Your instructor wants to know which framework you’re operating in and why.
Watch out for these in your own writing:
| Undefined term | What needs clarifying |
| “truth” | Correspondence, coherence, pragmatic, or deflationary? |
| “good” | Intrinsic, instrumental, hedonic, or virtue-based? |
| “free will” | Libertarian, compatibilist, or hard determinist? |
| “knowledge” | Justified true belief, reliabilist, or something else? |
| “consciousness” | Phenomenal, access, or self-consciousness? |
Define your terms early, stick to those definitions, and your argument will hold together much more cleanly.
Mistake 4: Arguing Too Much at Once
A common philosophy essay mistake, and one that’s almost never mentioned, is trying to prove too many things in a single paper. Students attempt to cover an entire debate, address every objection, and arrive at a sweeping conclusion, all within a few pages.
The result is an essay that touches on everything and develops nothing.
Strong philosophy essays make a small point very well. One clear argument, supported carefully, with objections addressed, is worth far more than five underdeveloped claims strung together. If your thesis requires three sentences to explain, it’s probably trying to do too much. Narrow it down until it fits one precise, arguable sentence.
Mistake 5: Skipping Steps in Your Reasoning
Philosophy is one of the few disciplines where showing your work is just as important as the conclusion you reach. If you jump from a premise to a conclusion without walking the reader through the logical steps in between, your argument hasn’t actually been made — you’ve just asserted a connection.
Here’s what that looks like in practice:
Skipped reasoning: “Since humans are rational beings, they must be treated as ends in themselves.”
Developed reasoning: “Kant argues that rational capacity is what gives a being moral worth. Since humans are rational, they possess that capacity. It follows, on Kant’s account, that humans cannot be treated merely as instruments — to do so would be to disregard the very feature that grounds their moral status.”
The second version shows the logical chain. Every step is visible. That’s what philosophy writing requires.
Mistake 6: Writing an Introduction That Doesn’t Set Up an Argument
A common philosophy essay introduction goes something like this: “Free will is one of the most debated topics in the history of philosophy. Many philosophers have held different views on this subject. This essay will examine arguments for and against compatibilism.”
That’s not an introduction — it’s an agenda. It tells the reader what’s coming, but says nothing about what position the essay will defend or why.
A strong philosophy introduction briefly sets the context, identifies the specific question being addressed, and ends with a clear thesis — a statement of what the essay is going to argue. Even one precise sentence at the end of your intro (“This essay argues that compatibilism fails because it conflates freedom from coercion with genuine metaphysical freedom”) transforms the whole paper. Your reader knows where they’re going, and you know what you have to prove.
Mistake 7: Ignoring Objections Entirely
Philosophy is fundamentally a dialogue. Any serious argument has responses, counterexamples, and objections attached to it. A paper that doesn’t acknowledge them looks one-sided to an instructor, even when the core argument is strong.
The good news is that you don’t have to solve every objection. You just have to show that you’re aware of the strongest ones, engage with them honestly, and either refute them or acknowledge what they reveal about the limits of your argument.
Students sometimes avoid counterarguments because they worry that it will weaken their position. The opposite is true. An essay that anticipates objections and addresses them is a much more persuasive piece of work than one that proceeds as if no disagreement exists.
Mistake 8: Forgetting That Philosophy Has Its Own Writing Conventions
Philosophy has specific expectations that differ from those of other humanities disciplines. First person is widely accepted — saying “I will argue that” is standard practice in philosophy papers and often preferred over impersonal constructions. Citation styles vary (Chicago and MLA are both common), but the key is consistency. And unlike in psychology, philosophy essays rarely rely on empirical sources — your primary evidence is the logical structure of the argument itself.
If you’re writing across multiple disciplines and find that some assignments feel more natural than others, that’s often because the writing conventions are genuinely different. When in doubt about your department’s specific expectations around citation format, first-person usage, or length of exposition, check your unit guide or ask your professor directly. Small misalignments with convention, repeated across a paper, add up.

FAQ
Can I use “I” in a philosophy essay?
Yes, and in most cases you should. Philosophy writing actively encourages first-person statements like “I will argue that” or “I take this objection to be decisive.” It signals confidence in your position and clarity about what you’re claiming. This is one area where philosophy differs noticeably from psychology or science writing.
How do I evaluate a philosophical argument without just listing pros and cons?
After presenting both sides, take a position. Which argument is logically stronger, and why? Identify the specific point where the weaker argument breaks down — a false premise, a hidden assumption, a logical gap — and explain why that matters. Your evaluation needs a verdict, not just a balance sheet.
How long should the exposition section of my essay be?
As short as it needs to be to make your critical engagement intelligible. A common guideline is no more than a third of your total word count on exposition. If you’re spending more than that explaining a view, you probably have less room left than you need for the analysis.
Do I need to cite sources in a philosophy essay?
Yes, for any specific claim, quote, or idea drawn from a text. The citation format varies by institution — Chicago and MLA are both common in philosophy. Your primary sources (the philosophical texts themselves) matter most; secondary literature supports your interpretations but should not replace your own argument.
My essay feels too short once I cut the padding. What do I do?
Go deeper, not wider. Develop one of your existing arguments further: add a concrete example, address an objection you glossed over, or push your analysis one step further than you currently have. In philosophy writing, depth of reasoning almost always matters more than breadth of coverage.
