Writing a Persuasive Argument for Philosophy Assignments

Writing a Persuasive Argument for Philosophy Assignments — And Why Most Students Miss the Point

Writing a persuasive argument for philosophy assignments begins with a misunderstanding most students carry into their first philosophy course: the belief that philosophy is about what you think. It isn’t. It is about what you can rationally defend. The moment you mistake a philosophy paper for a personal opinion piece, you’ve already lost half the marks. Writing argumentative essays in other disciplines shares some of this logic, but philosophy pushes it to its absolute limit — here, the argument structure itself is the primary subject of evaluation.

The University of North Carolina Writing Center’s philosophy handout puts it plainly: philosophy is the practice of making and assessing arguments. An argument, in this technical sense, is a set of statements — called premises — that work together to support another statement, the conclusion. Your professor does not want to know what you believe about free will, consciousness, or justice. They want to see whether you can construct a logically valid argument for a position, defend its premises, and honestly engage with the strongest objections.

What Is a Philosophical Argument — Really?

A philosophical argument is not a fight. It is a structured set of claims in which premises support a conclusion. Every philosophical argument has the same anatomy: one or more premises (statements offered as evidence or reasons) and a conclusion (the claim the argument is trying to establish). The relationship between premises and conclusion is everything. If the conclusion follows necessarily from the premises — meaning you cannot accept the premises as true and reject the conclusion without contradiction — the argument is deductively valid. If the conclusion follows with high probability from the premises, the argument is inductively strong.

The Internet Encyclopedia of Philosophy, a peer-reviewed scholarly resource co-sponsored by the University of Tennessee at Martin, defines a valid deductive argument as one “whose logical structure or form is such that if the premises are true, the conclusion must be true.” A sound argument adds one more requirement: the premises must actually be true. Your philosophy assignment is evaluated on both dimensions.

Why Philosophy Writing Is Different from Every Other Academic Essay

In history, you synthesize evidence. In literature, you interpret texts. In science, you design experiments. In philosophy, you do none of these things primarily — you analyze the logical structure of claims. The George Washington University Writing Program’s philosophy guide captures this precisely: philosophers are less interested in exhaustive surveys of the latest scholarship and more interested in the logical relationships between claims. Your philosophy paper should focus on a narrow set of arguments and investigate their logical inter-relations — not produce a broad literature review.

The Most Common Mistake: Choosing a Thesis That Isn’t Philosophical

Before you write a word of your persuasive philosophy argument, your thesis has to do real philosophical work. Swarthmore College’s Philosophy Writing Guide is explicit: your thesis must be arguable. If you assert a thesis against which no rational person could reasonably argue, you need a new thesis.

A philosophical thesis is a specific, contestable claim about a philosophical problem. “Abortion is wrong” is a position, but it’s so broad you could write ten books on it and not cover the terrain. “Thomson’s Violinist argument fails to justify abortion rights because it conflates positive and negative rights” — that is a philosophical thesis. It’s specific, it’s arguable, it engages a named philosopher’s argument, and it can be fully developed and defended in a 2,500-word paper.

Quick diagnostic: if your thesis is a question, it’s a topic — not a thesis. If it’s an empirically verifiable fact, it’s not philosophical. If no rational person disputes it, it’s not arguable. A philosophical thesis must be a claim that a reasonable, intelligent person could reject — and your job is to give them reasons not to.

Deductive vs. Inductive Arguments in Philosophy: Which One Should You Use?

When you’re writing a persuasive argument for philosophy assignments, one of the first decisions you face — often without realizing it — is whether your argument is deductive or inductive. Most philosophy assignments expect deductive arguments by default, but knowing the distinction with precision changes how you write, how you evaluate objections, and how confident you can be in your conclusion.

What Is a Deductive Argument?

A deductive argument is one in which the truth of the premises is supposed to guarantee the truth of the conclusion. If the argument is valid and the premises are true, the conclusion simply cannot be false. This is the most powerful form of argument — but also the most demanding. A deductive argument is either valid or invalid; there is no middle ground.

The classic example is the syllogism: All humans are mortal. Socrates is human. Therefore, Socrates is mortal. This is valid because the structure guarantees the conclusion. In philosophy assignments, most ethical and metaphysical arguments are intended as deductive: given these principles and facts, this conclusion must follow.

What Is an Inductive Argument?

An inductive argument is one where the premises support the conclusion with a high degree of probability — but not with logical necessity. Even if all the premises are true, an inductive conclusion could still be false. Inductive arguments are evaluated as strong or weak, not valid or invalid. The Stanford Encyclopedia of Philosophy’s treatment of inductive logic provides the most rigorous account available of how probabilistic reasoning works.

Validity, Soundness, and Why Students Confuse Them

In everyday English, “valid” means something like “reasonable.” In philosophy, it has a precise technical meaning: a deductive argument is valid if and only if the conclusion necessarily follows from the premises, regardless of whether the premises are actually true. You can have a valid but unsound argument: the structure is correct, but at least one premise is false.

Premise 1: All cats are made of chocolate. Premise 2: My pet is a cat. Conclusion: My pet is made of chocolate.

This argument is valid — structurally correct — but not sound because Premise 1 is false. When your professor says “your argument is valid but unsound,” they mean: your logic is correct, but one or more of your premises needs better defense. These are two entirely different problems requiring two entirely different fixes.

Abductive Reasoning: The Third Kind of Argument

A third form appears frequently in philosophy of mind, ethics, and philosophy of science: abductive reasoning, also called “inference to the best explanation.” Abduction reasons from observed evidence to the hypothesis that best explains it. In philosophy assignments, abductive reasoning appears most often in arguments about consciousness, the existence of God, and the reliability of perception. When writing a persuasive argument that uses abduction, be explicit about why your explanation is the best one — and address at least one competing explanation that rivals yours.

How to Structure a Persuasive Philosophy Assignment From Thesis to Final Paragraph

The structure of a persuasive philosophy assignment is not optional scaffolding — it is part of the argument itself. A philosophy paper without clear structure fails to persuade, not because the ideas are bad but because the reader can’t follow the logical progression from premises to conclusion. Jim Pryor’s widely referenced philosophy writing guidelines from NYU puts it directly: your paper must offer an argument; it cannot consist of the mere report of your opinions.

The Introductory Paragraph: Short, Precise, Declared

Your introduction has one job: announce your thesis and briefly indicate how you will argue for it. No grand historical sweep, no “since the dawn of time.” State your topic, state your thesis, and indicate the structure of your argument — what philosophers call a roadmap. The roadmap uses first-person: “I will argue that X. First, I will demonstrate Y. Then I will show that Z. Finally, I will address the objection that W.”

Model introduction: “This paper argues that psychological continuity is a necessary but insufficient criterion for personal identity. I will first reconstruct Locke’s memory theory of personal identity. I will then argue that this theory fails because it cannot account for cases of memory loss and fission without generating contradictions. I will conclude that a more adequate account must supplement psychological continuity with a criterion of physical continuity.” That’s 60 words. Every sentence earns its place.

Defining Your Terms — Before You Argue, Not After

One of the distinctive features of philosophy writing is the explicit definition of key terms before use. This is not pedantic — it is essential. Swarthmore’s philosophy guide explains: clear definitions are crucial because it is impossible to assess an argument if its terms are vague or ambiguous. If your argument turns on “free will,” “consciousness,” “justice,” or “moral responsibility,” you must define what you mean by those terms in your context.

Avoid Equivocation: The Deadliest Fallacy in Philosophy Assignments

Equivocation — using a term in two different senses across an argument — is the most common structural flaw in undergraduate philosophy papers. Example: “Laws must be obeyed. Gravity is a law. Therefore, gravity must be obeyed.” The word “law” means a legal rule in the first premise and a physical regularity in the second. The argument is invalid precisely because of this term-shift. Commit to one definition per key term and hold it throughout.

The Body of the Paper: One Argument Per Paragraph

Each paragraph in your philosophy paper should develop a single point. The paragraph structure follows a tight pattern: state the point (topic sentence), develop it with explanation and example, connect it back to your thesis. Nothing else. The reader should be able to trace a clear path: premise 1 established in paragraph 2, premise 2 established in paragraph 3, counterargument acknowledged in paragraph 5, rebuttal in paragraph 6, conclusion in paragraph 7.

The Conclusion: No New Arguments, Just Synthesis

A philosophy conclusion does not introduce new material. It gathers the threads of your argument, restates your thesis in light of what you have demonstrated, and — crucially — acknowledges the limits of your argument. What remains unresolved? What objections did you not have space to address? Swarthmore’s guide notes that ending philosophy papers with questions is not wrong — if you have unanswerable questions after completing your argument, the conclusion is the place to acknowledge them.

How to Build Premises That Actually Support Your Philosophical Conclusion

The most critical skill in writing a persuasive argument for philosophy assignments is premise construction. Most undergraduate philosophy arguments fail not because the thesis is wrong, but because the premises don’t adequately support it. Either the premises are stated too vaguely to do logical work, or they smuggle in assumptions that haven’t been defended, or they don’t actually connect to the conclusion without additional steps the student never supplies.

What a Premise Has to Do

A premise is a claim that functions as a reason to accept the conclusion. It has three requirements. First, it must be clearly stated — not vague or ambiguous. Second, it must be independently defensible — either self-evidently true, supported by evidence, or itself the conclusion of a sub-argument. Third, it must logically connect to the conclusion — either alone or in combination with other premises. Missing any one of these three produces an argument that doesn’t work, even if the underlying idea is philosophically interesting.

Avoiding Hidden Premises

Hidden premises — assumptions required for your argument to work but never stated explicitly — are the silent killers of philosophy arguments. A hidden premise is one your reader must supply themselves to make your argument valid. The problem: if the reader has to supply it, they may supply a false or contestable version, and they’ll rightly object that you never justified it. Surface all your premises explicitly.

Example: A student argues, “Voluntary euthanasia should be legal, because individuals should be free to make their own decisions about their bodies.” The hidden premise is something like “legal policy should reflect individual autonomy without exception.” But that premise is highly contestable — most societies legally restrict certain self-directed behaviors without abandoning the autonomy principle. By leaving the premise hidden, the student has produced an argument that appears to work but actually doesn’t.

Using Primary Philosophical Sources to Support Premises

In philosophy assignments, the primary sources are philosophical texts themselves — not secondary summaries or Wikipedia. When you claim “Kant’s Categorical Imperative holds that we should act only according to maxims we could will to become universal laws,” you are drawing on Kant’s Groundwork for the Metaphysics of Morals (1785). Your premise is established by citing and accurately interpreting that text. Swarthmore’s writing guide is clear: philosophy papers should mostly make use of primary sources — the philosophical texts themselves — with secondary sources playing a supporting role.

The Four Most Common Premise Errors in Student Philosophy Arguments

• Vague premise: “People generally agree that suffering is bad.” Agree in what sense? Bad compared to what? Make it specific.
• Unsupported premise: “Consciousness is entirely a product of brain activity.” This is one of the most contested claims in philosophy of mind — state it as a premise you will defend, not a given.
• False dichotomy premise: “Either determinism is true or free will exists.” This ignores compatibilism, which holds that both are true simultaneously.
• Begging the question: “Abortion is wrong because it involves taking a human life.” This premise assumes the conclusion (that a fetus counts as a human life in the morally relevant sense) — which is exactly what the debate is about.

How to Handle Counterarguments in a Philosophy Assignment (Without Undermining Your Own Position)

Every student who has sat down to write a persuasive argument for philosophy assignments has felt the dread of the counterargument section. What if the objection is too strong? What if I can’t refute it? This is exactly backwards. A strong objection isn’t a threat to your argument — it’s evidence that you’ve chosen a genuinely interesting philosophical position.

The Principle of Charity: State the Objection at Its Strongest

The most important rule for handling counterarguments in philosophy: always state the objection in its strongest possible form. This is called the principle of charity. If you knock down a weakened or distorted version of an opposing view — what logicians call a straw man — your refutation proves nothing.

What does charity look like in practice? If you are defending utilitarian ethics against a rights-based objection, don’t caricature it. Instead: “The strongest Kantian objection to utilitarianism holds that aggregating welfare across individuals treats persons as mere means to aggregate ends, violating the categorical imperative. This objection has genuine force because it targets the deepest structural feature of consequentialist thinking rather than a peripheral implication.” State it that clearly. Then refute it that specifically.

How to Structure a Counterargument Section

What to Do When You Can’t Fully Refute an Objection

Sometimes an objection genuinely threatens your thesis. The right response isn’t to pretend it doesn’t — it’s to modify your thesis to accommodate it. This is not intellectual capitulation; it is philosophical progress. “This objection shows that my original claim was too broad. A more defensible version of the thesis is…” demonstrates exactly the kind of responsiveness to argument that philosophy as a discipline values.

Using Thought Experiments: The Philosopher’s Experimental Method

One of the most powerful and distinctive tools in writing a persuasive argument for philosophy assignments is the thought experiment. The UNC Writing Center explains: if scientists want to test a theory or principle, they design an experiment. In philosophy, we test ideas by constructing imaginary cases that allow us to focus on the specific issue or principle we are most interested in. Thought experiments are not illustrations — they are logical instruments designed to isolate principles and reveal their implications.

The Greatest Thought Experiments in Philosophy — And What They Teach

John Rawls’s Veil of Ignorance (Harvard University)

John Rawls — philosopher at Harvard University and author of A Theory of Justice (1971) — devised one of the most influential thought experiments in political philosophy. Imagine you are choosing the basic principles that will govern your society, but you do not know your own position within it — your class, gender, race, talents, or conception of the good. What principles would you choose? Rawls argued you would choose principles that prioritize the worst-off members of society, since you could end up being one of them. This thought experiment operationalizes fairness as an impartial procedure rather than a substantive claim.

Judith Jarvis Thomson’s Violinist (MIT)

Judith Jarvis Thomson — philosopher at MIT — published one of the most discussed thought experiments in applied ethics in her 1971 essay “A Defense of Abortion.” The scenario: you wake up connected to a famous unconscious violinist whose life depends on your kidneys for nine months. Does your right to bodily autonomy permit you to disconnect? Thomson used this to argue that even if a fetus has a right to life, this doesn’t automatically override a pregnant person’s bodily autonomy. What makes this experiment uniquely significant is its precision: it isolates the question of bodily autonomy from questions about fetal personhood.

The Trolley Problem (Philippa Foot and Judith Jarvis Thomson)

The Trolley Problem, originated by Philippa Foot at Oxford University and developed by Thomson, presents a runaway trolley heading toward five people. You can pull a lever to divert it onto a track with one person. Should you? Most people say yes. But in a variant, you can push a large man off a bridge to stop the trolley. Most people say no — despite the same arithmetic. The thought experiment reveals that our moral intuitions are not purely consequentialist: how harm is caused (as a means vs. a side effect) matters morally to most people.

Plato’s Allegory of the Cave

Plato described prisoners chained inside a cave, able to see only shadows on a wall cast by objects behind them. One prisoner is freed and drags himself into sunlight, experiencing real objects for the first time. When he returns to tell the others, they disbelieve him. This thought experiment is uniquely significant in epistemology and metaphysics because it distinguishes appearance from reality and asks what it means to “know” something at all.

How to Use Thought Experiments Effectively in Your Assignment

A thought experiment in a philosophy assignment must do three things. First, describe the scenario with sufficient detail that the reader understands the philosophical principle it is designed to isolate. Second, draw out the relevant intuition — explain what most people’s reaction to the case would be, and why that reaction is philosophically significant. Third, connect the intuition to your argument — show how the intuition supports or challenges the principle you are arguing for. A thought experiment that just sits in the paper without explicit connection to your thesis is decoration, not argument.

Logical Fallacies That Kill Philosophical Arguments — And How to Avoid Every One

Writing a persuasive argument for philosophy assignments is half about building your argument well and half about not making the moves that destroy it. Logical fallacies are argument errors — patterns of reasoning that appear valid but aren’t. In philosophy, they are not just rhetorical flaws; they are structural failures that invalidate your argument entirely.

Spotting and avoiding these fallacies requires reading your own argument from the perspective of a hostile but fair reader. For every move you make, ask: “Does this actually prove what I need it to prove?”

Key Entities in Philosophical Argumentation: Philosophers, Schools, and Institutions

When writing a persuasive argument for philosophy assignments, demonstrating that you know the key figures, institutions, and texts in your area of philosophy signals genuine engagement with the intellectual community you are writing into. Philosophy is a conversation spanning 2,500 years, and your assignment is a contribution to that ongoing dialogue.

Aristotle and the Origins of Formal Logic

Aristotle (384–322 BC) — student of Plato at the Academy in Athens and founder of his own school, the Lyceum — invented formal logic in his Prior Analytics. He identified the syllogism as the basic unit of deductive reasoning, establishing the structure that philosophy still uses 2,400 years later. When a philosophy professor grades your argument for logical validity, they are evaluating it against standards Aristotle first articulated. His Nicomachean Ethics remains the foundational text for virtue ethics, and his Politics provides the framework for natural law theory.

Immanuel Kant — The Categorical Imperative and Deontological Ethics

Immanuel Kant (1724–1804) — philosopher at the University of Königsberg — developed the most influential deontological ethical theory in Western philosophy. His Categorical Imperative — “act only according to that maxim whereby you can at the same time will that it should become a universal law” — provides one of the most rigorous ethical frameworks available. Kantian arguments have a distinctly deductive character: from the nature of rational agency, specific moral duties follow necessarily.

John Stuart Mill — Utilitarianism and Consequentialist Logic

John Stuart Mill (1806–1873) — British philosopher and economist — developed the most systematic consequentialist ethical theory. His Utilitarianism (1863) and On Liberty (1859) are among the most assigned primary texts in undergraduate philosophy courses in the United States and United Kingdom. Arguments that apply Mill’s framework move from empirical premises about consequences to moral conclusions about permissibility.

John Rawls at Harvard University

John Rawls (1921–2002) — philosopher at Harvard University — published A Theory of Justice in 1971, arguably the most important work of political philosophy produced in the twentieth century. His theory of justice as fairness — grounded in the Veil of Ignorance thought experiment and the difference principle — provides the most influential framework for philosophical arguments about inequality, social policy, and political obligation in both US and UK university courses.

The Stanford Encyclopedia of Philosophy (SEP) and the IEP

Two online resources are academically credible for undergraduate philosophy citation. The Internet Encyclopedia of Philosophy (IEP), co-sponsored by the University of Tennessee, is a peer-reviewed philosophy reference accepted in most US university courses. The Stanford Encyclopedia of Philosophy (SEP) — maintained by Stanford University’s Metaphysics Research Lab — is the gold standard for online philosophical reference worldwide. Both are free, regularly updated, and written by academic philosophers. Always prefer these over non-academic philosophy websites for background reading and citation.

Writing Style for Philosophy Assignments: Precision Over Complexity

The most common stylistic mistake students make when writing a persuasive argument for philosophy assignments is confusing complexity with rigor. Philosophical precision doesn’t mean using longer words or more abstract sentence structures — it means saying exactly what you mean, nothing more, nothing less. Jim Pryor’s NYU philosophy writing guidelines are direct: be concise but explain yourself fully.

Use Simple Language to Express Complex Ideas

Swarthmore’s philosophy writing guide advises: be precise in both argument and word choice; use simple language and syntax; avoid excessive academic jargon. A sentence like “The ontological instantiation of phenomenal qualia in physicalist frameworks remains contested” communicates less precisely than “We don’t fully understand how physical brain processes produce conscious experience.” In philosophy, the goal is maximum clarity — not impressive vocabulary.

The First-Person Rule in Philosophy Papers

Philosophy is one of the few academic disciplines where first-person writing in your thesis and roadmap is not just acceptable — it’s expected. Phrases like “I will argue that…” and “I will defend the view that…” signal intellectual accountability: you are owning the argument. What professors discourage is hedging first-person: “I feel that…” or “I believe…” — these suggest personal feeling rather than argued position. Write “This argument fails because…” rather than “I think this argument fails because.”

Tense Consistency: Always Use Present Tense for Philosophical Claims

Always use the present tense when describing a philosopher’s argument, even if they lived five centuries ago. Write “Descartes argues that the mind and body are distinct substances,” not “Descartes argued.” GWU’s philosophy writing guide explains: arguments are treated as timeless contributions to the philosophical conversation, not historical events. Kant’s Categorical Imperative is a live philosophical position that still demands engagement today.

Citation in Philosophy: Primary Sources First, Secondary Sources Second

Philosophy assignment citation follows a distinctive hierarchy. Primary sources — the actual philosophical texts you are analyzing — are your most important citations. Kant’s Groundwork, Mill’s Utilitarianism, Rawls’s A Theory of Justice — cite these directly when making claims about what these philosophers argue. Secondary sources — commentaries, encyclopedia entries — support your understanding but should not dominate your citations. Swarthmore’s philosophy guide is explicit: make sure secondary sources do not dominate your paper.

Scope Discipline: Do Less, But Do It Completely

The single most reliable piece of advice for improving philosophy assignment marks: narrow your scope dramatically and treat that narrower topic with full rigor. Most undergraduate philosophy papers fail because they chose a topic too large to treat in the assigned word count. Pryor’s guidelines note that it is always better to concentrate on one or two points and develop them in depth than to cram in too much — “one or two well-mapped paths are better than an impenetrable jungle.”

Advanced Persuasion Techniques and Essential Vocabulary for Philosophy Assignments

Scoring at the highest level on persuasive argument for philosophy assignments requires more than correct structure. It requires demonstrating command of the discipline’s precise vocabulary and engaging with the more sophisticated argumentative moves that distinguish upper-level philosophy writing.

Necessary vs. Sufficient Conditions

Being able to distinguish necessary from sufficient conditions dramatically improves the precision of philosophical arguments. A necessary condition is something required for a claim to be true — without it, the claim cannot hold. A sufficient condition is something that, when present, guarantees the claim is true. Example: Having a brain is a necessary condition for human consciousness (no brain, no consciousness). But having a brain is not sufficient — computers have something analogous to signal processing but (probably) are not conscious. Many undergraduate philosophy arguments can be repaired by correctly specifying whether a proposed condition is necessary, sufficient, or both.

The Method of Cases: Testing Principles Through Edge Cases

One of the most powerful advanced techniques in philosophy is testing ethical or metaphysical principles through edge cases — cases specifically designed to reveal where a principle breaks down or generates counterintuitive results. If you are defending a utilitarian principle, construct a case where applying it consistently produces a result most rational people would reject as monstrous. Then either bite the bullet (accept the result and argue it isn’t as counterintuitive as it seems) or modify the principle. This “method of cases” is particularly common in applied ethics assignments involving Thomson, Peter Singer (Princeton University), and debates about animal rights and medical ethics.

The Reductio ad Absurdum: Philosophy’s Most Elegant Weapon

Reductio ad absurdum — reduction to absurdity — is an argument strategy where you demonstrate that a position entails an absurd or contradictory conclusion, thereby refuting the position. The strategy: take your opponent’s position as a premise, follow its logical implications faithfully, and arrive at a conclusion that is self-contradictory or clearly false. Example: “Suppose moral relativism is true — that moral claims are true only relative to cultural norms. Then ‘slavery is wrong’ was false in 1850s American culture but true now. But slavery was wrong in 1850, even though the culture permitted it. Therefore moral relativism generates absurd conclusions and must be false.”

Different Types of Philosophy Assignments and How to Approach Each

Not every philosophy assignment asks for the same thing. When writing a persuasive argument for philosophy assignments, the first task is understanding which of the four core assignment types you’re dealing with. Each requires a different primary emphasis, though all share the same foundational requirement: rigorous argument.

Type 1: Exposition and Reconstruction

In exposition assignments, you reconstruct a philosopher’s argument as accurately and clearly as possible. Your goal is not to evaluate it but to show that you understand it well enough to explain it to someone unfamiliar with the text. The UNC Writing Center notes that reconstruction requires you to identify and explicitly state the premises and conclusion, even when the philosopher left some steps implicit. Charity is essential: always reconstruct the argument in its strongest possible form.

Type 2: Critical Evaluation

Evaluation assignments ask you to assess a philosophical argument — is it valid? Are its premises defensible? Does the conclusion follow? Your evaluation must be specific, not general. “Kant’s argument is flawed” is an assertion. “Kant’s argument in the Groundwork fails because his first formulation of the Categorical Imperative, applied to the maxim of lying, generates a contradiction: it would prohibit lying even to prevent a murder, which most rational agents would find deeply counterintuitive” — that is an evaluation.

Type 3: Original Argument

Original argument assignments ask you to defend your own position on a philosophical question. This is the most demanding type and the one this guide primarily addresses. You must formulate a thesis, construct supporting premises, anticipate objections, and provide rebuttals — all while maintaining logical rigor and engaging the relevant philosophical literature. The aim is not just to name the parts, but to identify how they work and where the weaknesses are.

Type 4: Comparative Analysis

Comparative assignments ask you to examine how two or more philosophers or traditions approach a shared question. This is not a side-by-side description — it requires you to identify the deeper philosophical commitments that produce the different conclusions, evaluate which position is more defensible, and construct an original argument for your assessment. Example: “Compare Kant’s and Mill’s approaches to lying. Which provides the more defensible account?” A high-scoring response identifies that the disagreement traces back to a fundamental difference in moral ontology, then defends which foundation is more defensible.
