    Taught in schools: Lektury obowiązkowe – Polish national reading list (Poland), Turkish edebiyat curriculum (Turkey)

    Included in: Great Books of the Western World

  2. No. 2 on this list. Poetics

    Aristotle · c. 335 BCE

    Challenging3.4 hours

    The Poetics is required reading in virtually every university curriculum touching literature, classics, philosophy, rhetoric, or dramatic theory worldwide. It appears on syllabi across disciplines in every major educational system. No other single work in Western literary culture has maintained this breadth of curricular presence across two and a half millennia.

  3. No. 3 on this list. Symposium

    Plato · c. 385 BCE

    Moderate2.2 hours

    The Symposium is required reading in virtually every philosophy, classics, and great books curriculum worldwide. It appears on syllabi for philosophy of love, Platonic metaphysics, ancient literature, gender studies, and queer theory courses. Its influence has extended beyond the academy — the concept of 'Platonic love' and Aristophanes' myth of the divided self have entered everyday language. No significant Western education omits it.

  4. The Critique of Judgment is core curriculum in every philosophy department worldwide, foundational to the discipline of aesthetics, and required reading in the history of modern philosophy. While structured literary-syllabus data is unavailable in the database, its status as one of Kant's three Critiques—alongside the Critique of Pure Reason and Critique of Practical Reason—places it among the canonical texts of Western philosophy. It appears across thousands of university syllabi globally.

  5. Philosophical Investigations is required reading in virtually every anglophone philosophy department and appears on syllabi for philosophy of language, philosophy of mind, and analytic philosophy courses worldwide. Wikipedia carries a detailed article available in over 50 languages. It is consistently listed among the most important books of the 20th century across disciplinary surveys.

  6. The Summa Theologica is required reading in virtually every Catholic seminary and philosophy of religion program globally, and is foundational in scholastic philosophy curricula. Pope Leo XIII's encyclical Aeterni Patris (1879) formally designated it the basis for Catholic philosophical and theological education worldwide. It is among the most cited texts in Western intellectual history.

  7. Discipline and Punish is required reading in sociology, criminology, philosophy, cultural studies, history, and literary theory courses worldwide. It appears on thousands of university syllabi across disciplines, making it comparable in canonical weight to the most taught works of 20th-century thought. It is considered foundational for understanding modern social institutions across every field of the humanities and social sciences.

  8. Being and Time is required reading in virtually every philosophy curriculum worldwide and stands as one of the most taught works in continental philosophy. It appears on syllabi for philosophy, phenomenology, existentialism, cultural theory, and theology, and has been translated into dozens of languages. Few 20th-century philosophical texts achieve this breadth of curricular presence.

  9. Orientalism is required reading in postcolonial studies, comparative literature, cultural studies, history, and Middle Eastern studies curricula worldwide. It appears on thousands of university syllabi across disciplines and is considered foundational to the field of postcolonial criticism. No academic in the humanities can avoid engagement with Said's argument, making it one of the most canonical critical texts of the late 20th century.

  10. The Prince is required reading in political science, philosophy, history, and humanities curricula worldwide and is among the most widely assigned non-fiction texts in higher education. It appears on every syllabus for political philosophy and political theory, from introductory undergraduate courses to graduate seminars. Few texts of any era command this breadth of curricular presence.

  10. No. 20 on this list. On the Genealogy of Morality · Friedrich Nietzsche · 1887

    Friedrich Nietzsche opens by promising a history of morality and delivers something more unsettling: a prosecution. In three linked essays, he traces where our moral concepts actually came from — not from reason or God, but from power, debt, and pain. The first essay tracks how the word 'good' belonged originally to the aristocrat who named himself that way, then watches the slave revolt in morality invert the table of values entirely, creating 'evil' as a name for the strong. The second follows the concept of guilt back to the creditor-debtor relationship, where punishment began not as justice but as the pleasure of cruelty legitimized by contract. The third anatomizes the ascetic priest — the figure who turns suffering into meaning, who wins power over the powerful by teaching them to hate themselves. Nietzsche writes in long hypotactic periods that build to sudden one-line reversals, embedding Latin phrases and German coinages into arguments that span etymology, biology, and cultural history simultaneously. The tone is the provocation: he performs the very diagnosis he conducts, and readers who take his endorsements of aristocratic violence at face value have missed the argument. This is the book that taught Foucault to ask how systems of knowledge produce what they claim merely to describe. It demands and rewards slow, combative reading.

About this list

These 100 books are the highest-scoring eligible philosophy books currently in the catalogue. By literary regard, it opens with Republic, Poetics and Symposium. About 1,476 hours of reading in all. Difficulty runs from 57 to 76 out of 100 for the middle half of the list; the summit is Écrits at 94.

This list is ranked by literary regard, with a consistent order for equal scores. Membership follows authors and co-authors, not translators or editors. Catalogue coverage and the historical canon both limit what this list can represent, and genre labels are the catalogue’s own, gathered into broader kinds.

When we matched the Canons dataset to our catalogue in October 2026, our canonical-status scores rose with the number of school curricula, publisher series and lists in it that cite a work: the median score was 72 for books one such source cites, 84 at two, 88 at three, 92 at four and 93 at five or more. Prizes are left out of that count. Outside the state curricula, the dataset’s sources choose mostly from what has been translated into English or French, so it is a weaker check on other literatures.

Questions people actually ask

What are the best philosophy books?
By literary regard, which weighs canonical status, critical standing and influence, Republic, Poetics, Symposium, Critique of Judgment and Philosophical Investigations lead. ReadingRate ranks 100 such books, each with a difficulty score and a reading-time estimate.
Where should I start with philosophy books?
Start from difficulty, not from rank. The most approachable books on this list that still carry top literary regard are Enchiridion by Epictetus (about 22 min), A Theory of Justice by John Rawls and The Bhagavad Gita by Vyasa.
How hard are philosophy books to read?
Most of this list sits between 57 and 76 on ReadingRate's 100-point difficulty scale, where 40 to 55 is moderate. The summit is Écrits at 94. Every entry carries its own score, so a reader can pick a great book at a difficulty they will finish.
How is this list ranked?
On literary-regard data: how canonically established a work is, its critical standing, and its influence on later writing. It is not a readers’ poll, which is why recent bestsellers rarely appear. Membership follows authors and co-authors, not translators or editors. A list that is not a genre list keeps to literature (fiction, poetry, drama and philosophy), with philosophy taking no more than one slot in five while there is literature left to rank; every list holds at most three works by one author.
