, Science and Hypothesis1902 (Eng. 1905)
The philosophical status of scientific theory — conventionalism, geometry, and the limits of proof.
Syntopi.com's 102 Great Ideas and their indexed passages are faithful to the 1952 Great Books of the Western World canon — Homer through Freud. Every passage in the primary corpus comes from those authors. This page lists them in chronological order with bios, works, and free public-domain links where available, alongside the non-canonical 1990 expansion (Volumes 56–60, twentieth-century authors) as suggested further reading beyond the canon. Most 1990 works remain in copyright and are linked to publisher/library-side pointers rather than embedded.

The 1990 expansion · twentieth century
Einstein to Woolf
39 twentieth-century works Britannica added in the 1990 second edition (Volumes 56–60) — Einstein, Keynes, Weber, Lévi-Strauss, Joyce, Woolf, Kafka. Bibliography only; linked to public-domain editions where available, library finders otherwise.
In 1990, Britannica and Mortimer Adler published a second edition of the Great Books of the Western World, adding six volumes of twentieth-century writers — Volumes 56–60 — to extend the conversation past Freud. The additions broke into five themed volumes. Most of these works remain under copyright, which is why this site does not include their texts inline. The entries below name them instead, with free public-domain editions linked where they exist and library-finder pointers where they don't.

Sister projects · the wider public-domain web
Where else to find primary sources
Ten non-profit projects Syntopi.com leans on, learns from, or simply admires — Project Gutenberg, the Internet Archive, Perseus, Standard Ebooks, and others. Free, public-domain, and run by people who think the canon belongs to everybody.
Syntopi.com is one project in a long tradition of free public-domain text work. The list below is not exhaustive — it's the projects we use, point to most often, or admire enough to send readers their way. Several feed directly into our pipeline (Gutenberg, Internet Archive, Standard Ebooks); others cover ground the 1952 canon doesn't (Sacred Texts, Wikisource), or do something we can't (LibriVox's human-narrated audiobooks, Perseus's morphological lookup).
- Standard Ebooks — Volunteer-driven project that takes public-domain books and produces beautifully typeset EPUBs. The thinking-person's antidote to ugly Gutenberg formatting.
- Perseus Digital Library — Tufts' classical-text database. Greek and Latin works in the original language with parallel translations and morphological tools. The standard for serious classical study online.
- Project Gutenberg — The original free-ebook archive. 70,000+ public-domain works, the source many other projects (this one included) draw from.
- Internet Archive — The world's largest free digital library. Texts, audio, video, software. Syntopi.com pulls our author-voice recordings from here.
- Wikisource — Wikipedia's sister project for primary-source texts. Collaboratively transcribed and translated, with revision history and citations.
- LibriVox — Free audiobook recordings of public-domain works, narrated by volunteers worldwide. Complements our AI narration with human voices for the same texts.
- Public Domain Review — Curated essays and themed collections drawn from public-domain works. Strong editorial sensibility; the closest the open web has to a literary magazine of the canon's margins.
- HathiTrust Digital Library — Partnership of academic libraries. Roughly 17 million digitized volumes; access depends on copyright status and institutional affiliation, but the public-domain catalog alone is enormous.
- Online Library of Liberty — Liberty Fund's collection of classical-liberal and Western political-philosophy texts in HTML and EPUB. Strong on the political and economic thinkers in our corpus — Locke, Hume, Smith, Mill, the Federalists.
- Sacred Texts Archive — Primary religious texts across traditions — Vedic, Buddhist, Confucian, Zoroastrian, Norse, indigenous, and more. Covers material the 1952 canon largely doesn't.
