Philosophy PhD Writing Sample and Statement Guide
Philosophy PhD writing sample limits at 6 departments, from 4,500 words to 30 pages, a short statement of purpose example, and two AI rules in full.
Philosophy PhD Writing Sample and Statement Guide
A philosophy PhD application asks for a long argued paper and a short statement. Rutgers wants a writing sample of 4,500 to 7,500 words and a statement of roughly 300-500 words. Berkeley caps the sample at 20 pages; Harvard accepts 12 to 30.
Most of your revision time belongs to one paper, cut to fit each department. Below are six departments' rules side by side, a procedure for turning one paper into each version, and a constructed short statement. When your statement is drafted, a free Quick Review against the scholar-voice rubric reads it for your own reading of the field and the decisions behind your work.
Every department page quoted below was checked on October 30, 2026. Several pages state no admission year; the table says which. Recheck each page before you submit.

The rules you are writing inside: six departments
| Department | Statement(s) | Writing sample | GRE |
|---|---|---|---|
| Rutgers (September 2027 entry; deadline January 4, 2027) | Personal statement "of roughly 300-500 words" | 4,500 to 7,500 words ("ideally") | "Submission of GRE scores is now required." |
| Pittsburgh (2026-27 admissions season) | Statement of purpose with "career objectives and reasons for wanting to undertake graduate study in Philosophy at the University of Pittsburgh" | "an essay of about 20 to 25 pages"; apply page: name "clearly indicated on the first page" | "optional for the 2026-27 admissions season" |
| Harvard (Griffin GSAS) (no year stated) | Personal statement: "Required" | 12 to 30 pages; 8.5 × 11 inch, 1-inch margins, double-spaced, 12-point | General GRE: "Required" |
| UC Berkeley (no year stated) | Statement of purpose and personal history statement | "no more than 20 pages"; "A good target length … is 15-20 (double-spaced) pages" | None listed |
| Purdue (no year stated) | Academic statement of purpose, "only 1-2 pages", and personal history statement | Best philosophy paper; another field allowed if you have none | "GRE Scores (Optional)" |
| Yale (GSAS) (deadline January 2; no year stated) | Not specified on this page | "A writing sample is required by this program." | "GRE is optional." |
Read across the rows:
- Rutgers measures in words; every other stated limit is in pages. A 7,500-word paper fits Berkeley's 20 pages only at 375 words a page (our arithmetic: 7,500 ÷ 20). Measure your own rate before you assume.
- GRE rules split three ways: required, optional, or not listed (see the table). Do not copy one department's answer onto another.
- Two departments want a second essay. Berkeley and Purdue ask for a personal history statement next to the statement of purpose. Harvard's page lists only a personal statement, so check the application form for what that one document must cover.
- Rutgers publishes its odds. Its FAQ says: "We admit roughly 2-3% of approximately 400 applications submitted each year." That is a share of applications at one department, not a field-wide rate.
What each document has to prove
The departments describe the sample in demanding terms. Harvard: "The sample must address a substantial philosophical problem, whether it is an evaluation or presentation of an argument, or a serious attempt to interpret a difficult text." Berkeley: "it should go beyond mere exposition or superficial analysis of a philosophical text or problem." Purdue: "it should contain some insight of your own (as opposed to merely summarizing something somebody has written)."
The statements are routing documents. Purdue says: "In our admissions process, we prioritize applicants whose research background and interests fit well with those of our faculty." Pitt: "You should do your best to explain why the program is a good fit for you and why you are a good fit for the program." Berkeley asks you to declare a concentration there: applicants for Ancient Philosophy or History and Philosophy of Science "should indicate this in their statement of purpose".
Our view: treat the sample as the main exhibit and spend most of your revision time on it. The basis is the departments' own numbers: at Rutgers the sample is 9 to 25 times the length of the statement (our arithmetic: 4,500 ÷ 500 and 7,500 ÷ 300). No department publishes how it weights the two documents, so that weighting is unknown.
The countercase: at a fit-first department like Purdue, the statement does real selection work by the department's own account. If your list is full of such departments, the faculty paragraph deserves the same care as the paper.
None of the six pages uses the terms "area of specialization" or "AOS". Say what you want to work on as problems and figures, which is how Purdue phrases its question: "What topics/research areas, historical figures, specific puzzles or questions have you most enjoyed studying".
Choosing the paper
- Pick your best argued paper, not your most on-topic one. Purdue says: "The paper need not represent your primary interests in philosophy. For instance, you might think you are mainly interested in philosophy of mind, and yet you might still submit a paper on a topic in ethics if it is your best work to date."
- It must argue. If the paper mainly reports what an author says, it fails Berkeley's "beyond mere exposition" test and Purdue's "insight of your own" test. Add or sharpen your own objection and reply before you polish anything else.
- Use a philosophy paper if you have one, and revise it. Purdue allows another field only "If you do not have an eligible piece of writing from a philosophy course". For revision limits across fields, see our grad school writing sample guide.
If your sample and statement point at different areas, our guide to whether a literature writing sample must match the SOP works through the same problem in another humanities field.
Cutting one paper into each department's version
Run this procedure once, on your real paper:
- Format it to Harvard's specification: 8.5 × 11 inch page, 1-inch margins, double-spaced, a common 12-point font such as Times New Roman. That is the only fully stated page format among the six.
- Record two numbers: the word count and the page count in that format. Divide words by pages. That is your words per page.
- Convert each limit into words using your own rate, then cut to the smallest version you need.
- Cut whole moves, not sentences. Remove a second objection, a long survey of the literature, or a historical aside. Keep the thesis, the main argument, the strongest objection and your reply.
Constructed example: one 7,200-word paper, four limits
Constructed example, written by us, not a real applicant's paper. Context (invented): a 7,200-word paper on moral luck that runs 26 pages in Harvard's format, so about 277 words a page (our arithmetic on invented numbers).
| Department | Limit | What the invented paper needs |
|---|---|---|
| Rutgers | 4,500 to 7,500 words | Fits at 7,200 words. No cut |
| Harvard | 12 to 30 pages | Fits at 26 pages. No cut |
| Pittsburgh | about 20 to 25 pages | Cut about one page, roughly 280 words |
| Berkeley | no more than 20 pages | Cut about 1,660 words, to about 5,540 (20 × 277) |
For the Berkeley version, the invented applicant drops a 900-word section answering a second objection and cuts a 1,500-word literature survey to 700 words, removing 1,700 words in all. The thesis and the reply to the strongest objection stay intact. If your paper is already under 20 pages, keep one version for everyone.
What the short statement must contain
Build it from the departments' own questions. Purdue's cover what the others ask:
- Your interests as problems. Name two or three questions and the figures or debates they come from.
- Why a PhD, and what after. Purdue: "Why are you seeking a PhD in philosophy? What are your goals or plans post-PhD?" Pitt wants "career objectives".
- Why this department. Purdue: "it is especially useful if you mention specific faculty you would like to work with". For how naming works under different admission models, see should you name a professor in your SOP.
- Declarations the department needs. Berkeley's Ancient Philosophy and HPS concentrations must be stated in the statement of purpose.
- One sentence connecting the sample. If the sample is in a different area, say so in a clause and say what it shows about how you argue.
How much theory to put in the statement is its own question; see talking about theory in a statement of purpose.
Constructed example: a 368-word philosophy statement
Constructed example, written by us, not a real applicant statement. Context (invented): an applicant whose interests are philosophy of mind and epistemology, sending a sample in ethics. Faculty names are placeholders.
I want to work on two connected questions in philosophy of mind and epistemology. First, can introspection give us knowledge of our own beliefs, or only of our judgments about them? Second, if self-knowledge is partly constituted by the act of judging, what happens to that account when the judgment is mistaken?
I came to the first question through a seminar on self-knowledge, where I wrote a paper arguing that the transparency method explains knowledge of what we believe but not of how strongly we believe it. I came to the second through an independent study on delusion, where I read case reports alongside work on doxastic agency and became convinced that these are cases in which judgment and belief come apart.
My writing sample is in ethics, not mind. It argues that the problem of resultant moral luck does not show that our practice of blame is incoherent, because blame tracks the agent's relation to the outcome, not only her will. I chose it because it is my most fully argued paper: it states a thesis, answers the two strongest objections to it, and defends one reply at length. The same method, finding where an intuitive principle overreaches and restricting it, is the one I want to apply to self-knowledge.
[Department] is the right place for this work for three reasons. [Professor A]'s work on the epistemology of introspection is the most direct engagement I have found with my first question. [Professor B]'s work on belief and agency would shape how I approach the second. The department's reading group in philosophy of psychiatry would give me a place to test the empirical claims my second question depends on.
My undergraduate record includes one weak semester in my second year, when I was working twenty hours a week; my grades in philosophy since then are on the transcript.
After the PhD I intend to teach and do research in philosophy. I have worked as a writing tutor for two years and want teaching to be part of my graduate training. I am applying because I want five years to turn two questions into one argued position, and I want to do it among people already working on them.
That statement is 368 words inside the quote (our count), inside Rutgers's 300-500. For a department that allows 1–2 pages, expand the second paragraph with one more paper, add a sentence per named faculty member on what in their published work you would build on, and state a concentration where the department asks for one.
Program rules on AI and outside help
Of the six department pages in the table, only Rutgers's states a rule on AI. It reads, in full:
"Apart from copy editing for spelling and grammar, applicants must refrain from using AI (artificial intelligence) in the writing of their personal statement or writing sample. We may screen for use of AI as part of our review of applications."
The rule covers both the personal statement and the writing sample. Outside the table, UChicago's Division of the Arts & Humanities, which takes applications for its philosophy PhD, states a division-wide rule on its How to Apply page: "The use of generative AI in the production of application materials is considered plagiarism, and therefore, it should not be used."
The other five pages in the table say nothing on AI; that is not the same as a permission. If a school publishes no AI rule, the certification inside the application is what you sign, so read it there.
Before you upload the sample and statement
- Your sample states a thesis on the first page and argues for it.
- Each version meets that department's limit, measured in its own unit: words at Rutgers, pages elsewhere.
- The Harvard version uses Harvard's page format; the Pitt version has your name on the first page.
- Your statement names problems, not a list of fields.
- If the sample is outside your main area, one clause says so and says what it shows.
- Each department's version names faculty with a reason, and declares a concentration where Berkeley asks.
- The statement is within the length each department gives: about 300-500 words at Rutgers, 1–2 pages at Purdue.
- You have read each department's AI rule and the certification in each application.
Questions about philosophy PhD writing samples and statements
How long should a philosophy PhD writing sample be?
It depends on the department: 4,500 to 7,500 words at Rutgers, about 20 to 25 pages at Pitt, 12 to 30 pages at Harvard, and no more than 20 pages at Berkeley. Convert each into your own words-per-page rate before you cut.
Does the writing sample have to be in my intended area?
Not at Purdue, which says so in writing. The other five pages do not address it. Choose your best argued paper and explain the connection in one sentence of the statement.
Do philosophy PhD programs require the GRE?
Some do. Rutgers and Harvard require it, Pitt, Purdue and Yale list it as optional, and Berkeley's list of materials does not include it.
For writing-sample lengths across other fields, see our writing sample length by field guide. If your best paper is years old, read how to build a writing sample after years away from study. History departments weigh the sample differently; the history PhD statement of purpose guide quotes Columbia, Berkeley and Princeton.
Philosophy of religion applicants applying to religion departments should read the religious studies PhD statement of purpose guide on field declarations and language plans.
