Checked 28 September 2026. From the official GATE 2027 XH4 and XH0 syllabi (IIT Madras), the GATE 2026 XH-C4 and XH-B1 syllabi (IIT Guwahati), the GATE 2027 brochure and the official papers and keys 2023–2026. The line-by-line comparison and the question mapping are ours.

GATE 2027 brings real changes for Philosophy. The code changes first: XH-C4 Philosophy becomes XH4, and the compulsory Reasoning and Comprehension part, XH-B1, becomes XH0. Then the content. Classical Indian Philosophy (Section 1) is the same apart from two small wording fixes. Contemporary Indian Philosophy (Section 2) is rewritten: M.N. Roy is gone, Daya Krishna is in, and almost every other thinker has a new topic list. Western ethics and political philosophy grow, with the Gettier problem, care ethics, professional, environmental and bioethics, Nozick, Judith Butler and Habermas added. Levinas, Code and Harding, and Gilligan and Noddings are dropped. This guide sets out every change against the 2026 text and then checks which of the 2023–2026 questions no longer fit.

Where other pages get this wrong

For GATE 2027 the application portal opened on 2 September 2026. Regular registration now closes on 5 October 2026 and the late-fee window on 12 October 2026. The 2027 codes are XH0 and XH4.

Commonly published instead: Pages written in August, including an earlier ProSyllabus notice for this paper, still say the portal opened on 27 August, give 27 September and 5 October as the closing dates, and use the old codes XH-B1 and XH-C4.

GATE 2027 notifications and important-dates pages (IIT Madras), checked 28 Sep 2026. The brochure, revised on 27 Sep 2026, gives the same closing dates.

The 2027 paper: new codes, same marks

The Humanities paper still has three parts. General Aptitude and Reasoning and Comprehension are common to every Humanities candidate. The optional section, Philosophy for you, is scored and ranked separately: the brochure promises a separate score and rank for each section, so a GATE Philosophy rank is a rank among Philosophy candidates only. About 570 of them appeared in 2026. Nothing about the marks changed between 2026 and 2027. Only the codes did.

Section 2, Contemporary Indian Philosophy: rewritten

This is the largest change. The 2026 list had ten thinkers. The 2027 list also has ten, but not the same ten: M.N. Roy (Radical Humanism and Materialism) is dropped and Daya Krishna, with his essay “Three Myths about Indian Philosophy”, is added. Of the other nine, Iqbal’s list is closest to 2026: reworded, with Man and Superman added. Several changes remove exactly what past papers asked. Ambedkar loses Annihilation of Caste and Neo-Buddhism, and gains the Basic Features of the Indian Constitution and Untouchability. Gandhi loses Trusteeship and gains the critique of modern civilisation in Hind Swaraj. Krishnamurti loses Education, and Aurobindo loses the Four Theories of Existence.

GATE 2026 XH-C4 and GATE 2027 XH4 syllabi, Section 2; the comparison is ours. Topic names are the syllabus wording, lightly shortened.

Section 3, Classical and Modern Western: ethics and politics grow

Metaphysics and Logic are unchanged in substance. Epistemology gains one line, “The Gettier Problem and major responses to it”. Ethics is rebuilt: it adds ethical anti-realism, care ethics, professional ethics, environmental ethics and bioethics, and it drops Sidgwick, the line on intuition in teleological and deontological theories, and the named trio emotivism, prescriptivism and descriptivism (cognitivism and non-cognitivism stay). Social and Political Philosophy absorbs the liberal and feminist political theory that used to sit in Section 4.

Part of Section 3Added in 2027Dropped from 2026
EpistemologyThe Gettier Problem and major responses to itNothing
EthicsEthical anti-realism; Care Ethics; Professional Ethics (corporate governance and social responsibility); Environmental Ethics (Leopold’s land ethic, Naess’s deep ecology, Singer on animal rights); Bioethics (autonomy, beneficence, non-maleficence, justice; doctor–patient relationship; euthanasia)Sidgwick; intuition in teleological and deontological theories; emotivism, prescriptivism and descriptivism by name
Social and PoliticalNew to the syllabus: civic virtue; Judith Butler. Moved in from Section 4: Rawls (veil of ignorance, principles of justice), Nozick’s libertarianism, Beauvoir (now under feminist political theory), Charles Taylor’s multiculturalism, the capability approachNothing
MetaphysicsWording onlyNothing
LogicNoneNothing

GATE 2026 XH-C4 and GATE 2027 XH4 syllabi, Section 3; the comparison is ours. Nussbaum’s name no longer appears; the capability approach does.

Section 4, Contemporary Western: some thinkers out, one in

Thinker or topic2027 status
HabermasAdded: communicative rationality
SartreTypes of Being added; “Humanism” dropped; freedom and bad faith kept
NietzscheIdea of the Overman added
RortyOnly the critique of representationalism is kept

Code and Harding (situated knowledge)Dropped
Gilligan and Noddings (care versus justice)Dropped from Section 4; care ethics is now a Section 3 heading
BeauvoirEthics of Ambiguity dropped; she is now under feminist political theory in Section 3
Rawls, Nozick, Taylor, NussbaumMoved to Section 3 (Nussbaum’s name dropped)
Frege, Logical Positivism, Moore, Russell, Wittgenstein, Ryle, Quine, Strawson, Husserl, Heidegger, Merleau-Ponty, James, DeweyUnchanged

GATE 2026 XH-C4 and GATE 2027 XH4 syllabi, Section 4; the comparison is ours.

Section 1, Classical Indian Philosophy, is the stable part of the paper. The only differences are a typo corrected (“marerislism” becomes materialism in the Cārvāka line) and “Dharma- Svadharma” shortened to “Svadharma”. Every school from Sānkhya to Śāktism keeps its list. That matters, because Section 1 averaged 19.5 of the 60 marks from 2023 to 2026 by our count, and 27 marks in 2026.

Past questions that no longer fit

We mapped all 156 Philosophy questions of the 2023–2026 papers onto the 2027 syllabus. Most still fit. Ten questions, worth 18 marks over the four years, test topics the 2027 syllabus drops by name. Five more (9 marks) sit on topics that moved from Section 4 to Section 3, which changes nothing for your preparation. A third group matters more than it looks: nine questions (17 marks) tested things neither syllabus names, such as Moore’s open-question argument or Mill’s harm principle, and that group has grown every year.

Marks out of 60, from the table above. Our classification of the official papers.

Two readings follow, both ours. First, do not throw away the dropped questions. They still train the skill the paper tests, reading a thinker’s claim closely, and some dropped topics sit next to kept ones (Ambedkar on democracy is still listed; Krishnamurti’s choiceless awareness is still listed). Second, do not treat the syllabus as a closed list. The 2026 paper set 10 marks on things neither syllabus names: Dignāga’s apoha, Mill’s harm principle, a text-to-school match, a concept match across Ryle, Hegel, Moore and Heidegger, and scepticism in Nāgārjuna, Śrīharṣa and Jayarāśi. The setters read the syllabus as the map of a field, not a fence.

New ground: topics with no past questions

The new lines have never been examined, so there is nothing to copy. Our suggestion is the depth of a standard undergraduate textbook chapter: what the position claims, the one or two standard objections, and the names attached to it. That is the level the paper already sets in one- and two-mark MCQs and MSQs.

New in 2027What a question can testSection
Gettier problemWhy justified true belief is not enough; the no-false-lemmas, defeasibility and reliabilist responses3 Epistemology
Care ethicsCare versus justice; relational self; who is associated with it3 Ethics
Environmental ethicsLeopold’s land ethic, Naess’s deep ecology, Singer’s equal consideration of interests3 Ethics
BioethicsThe four principles; informed consent; active versus passive euthanasia3 Ethics
Professional ethicsCorporate governance and social responsibility3 Ethics
Judith Butler; civic virtueGender as performative; republican civic virtue3 Social and Political
HabermasCommunicative versus instrumental rationality; ideal speech situation4
Daya KrishnaThe three myths: Indian philosophy as spiritual, as authority-bound, as system-bound2
Gandhi’s Hind SwarajCritique of railways, lawyers, doctors and modern civilisation2

Our reading of the 2027 syllabus lines. The “what a question can test” column is our suggestion, not an official weighting.

Reasoning and Comprehension: renamed, not rewritten

The compulsory 25-mark part keeps its content under the new code XH0, with four numbered parts: reading comprehension, expression, analytical reasoning and logical reasoning. In the 2023–2026 papers it was mostly analytical puzzles: an average of 14.75 of its 25 marks by our count, against 2.75 for reading comprehension. The booklet was the same for every Humanities section. Our separate XH0 guide goes through it question by question; it is linked at the foot of this page.

XH0 skillAverage marks 2023–2026 (of 25)
Analytical reasoning14.75
Expression4.5
Logical reasoning3.0
Reading comprehension2.75 (none in 2026)

Our classification of the official XH-B1 papers and keys, 2023–2026.

Practise it, don't just read it

Classical Indian Philosophy is unchanged and averaged 19.5 of 60 marks. Keep Sānkhya, Nyāya and Advaita sharp while you add the new Western and Contemporary Indian lines.

The ProSyllabus GATE Philosophy library has ten topic quizzes today: Aristotle’s Four Causes Fundamentals, Nyaya Means of Knowledge Fundamentals, Classical Indian Schools: Samkhya and Vedanta, Descartes and Rationalism, Kant’s Categorical Imperative, Rawls’ Original Position Advanced Challenge, and practice quizzes on Ethics, Logic, Social and Political Philosophy and Contemporary Western Philosophy. There is no Contemporary Indian quiz yet; for that section work from the official papers.

What is XH4 in GATE 2027?

XH4 is the new code for the Philosophy section of the GATE Humanities and Social Sciences paper. It was XH-C4 until GATE 2026. The compulsory Reasoning and Comprehension part is now XH0 (was XH-B1).

What changed in the GATE Philosophy syllabus for 2027?

Contemporary Indian Philosophy is rewritten: M.N. Roy is dropped, Daya Krishna is added and most thinkers have new topics. Western ethics adds anti-realism, care, professional, environmental and bioethics. Epistemology adds the Gettier problem. Social and political philosophy adds Rawls, Nozick, civic virtue, Beauvoir, Judith Butler, Taylor and the capability approach. Habermas is added; Levinas, Code and Harding, and Gilligan and Noddings are dropped. Classical Indian Philosophy is unchanged.

Is M.N. Roy in the GATE 2027 Philosophy syllabus?

No. M.N. Roy (Radical Humanism and Materialism) was in the 2026 syllabus and is not in the 2027 XH4 syllabus. Daya Krishna is the new name in Contemporary Indian Philosophy.

Is Annihilation of Caste still in the GATE Philosophy syllabus?

No. For 2027 the Ambedkar topics are the Basic Features of the Indian Constitution, Untouchability and Democracy. Annihilation of Caste, Neo-Buddhism, and Natural Rights and Law are no longer listed. The 2026 paper asked about Annihilation of Caste (Q62).

How many marks is the Philosophy section in GATE XH?

60 marks from 39 questions (18 one-mark and 21 two-mark). The paper also has Reasoning and Comprehension (25 marks) and General Aptitude (15 marks), for 100 marks in three hours.

Can I change my XH section after applying?

Changes of paper are allowed in the correction window, 14 to 21 October 2026. The section cannot be changed in the exam hall.

Where is the GATE 2027 Philosophy syllabus PDF?
