Pith's one-line read Wikipedia treats philosophers as reference hubs rather than foundational sources, and hidden network structure exposes unstated links among Presocratics.
desk verdict Solid application of reduced Google matrix to philosophers, but the Western-dominance and reference-hub claims rest on a biased sample and need re-analysis. read the letter →
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The carrying mechanism is the Google matrix $G = \alpha S + (1-\alpha)/N$ of a directed Wikipedia edition, with $\alpha = 0.85$, together with its PageRank eigenvector $P$ and the CheiRank eigenvector $P^*$ computed on the reversed link network. PageRank measures how much an article is pointed to by influential pages; CheiRank measures how much an article points toward influential pages. For the 21 Presocratics, the paper uses the reduced Google matrix $G_R = G_{rr} + G_{pr} + G_{qr}$, where $G_{rr}$ contains direct transitions among the selected nodes, $G_{pr}$ reproduces the already-known reduced PageRank distribution, and $G_{qr}$ collects transitions that travel through the rest of Wikipedia before returning to the selected set. The $G_{qr}$ component is the instrument that exposes hidden links, and the $\Theta$-score aggregates per-edition PageRank ranks into one cross-cultural list.
What would settle it
Rebuild the rankings from seed lists drawn independently for each language edition and check whether the all-Western top 38 of the $\Theta$-score survives; if it dissolves, that result is a selection artifact. Separately, recompute the $G_{qr}$ hidden links for the Presocratics using $\alpha = 0.5$ and using a later English Wikipedia snapshot; the Leucippus–Parmenides and Melissus–Xenophanes links should persist if they reflect stable structural relationships rather than one snapshot's particular hyperlink choices.
Extended reading notes
Core claim
The central claim is that Wikipedia's philosopher subnetwork is a landscape of influential reference points rather than a genealogy of foundational sources. In the PageRank–CheiRank plane, the 237 philosopher articles sit mostly above the diagonal, the region of nodes that receive many links from the rest of the encyclopedia while sending few links outward. Aristotle and Plato lead almost every edition, but each language inserts its own local figures, and the aggregated $\Theta$-score places only Western philosophers in the top 38 positions. Rankings from two specialized philosophical encyclopedias differ by Kendall distances of about 0.36 to 0.41 from the Wikipedia rankings, and the paper attributes this gap to Wikipedia encoding broad societal influence while specialized encyclopedias encode academic standing. For the 21 Presocratics in the English edition, the reduced Google matrix is split into direct transitions, a trivial PageRank term, and a hidden-transition part $G_{qr}$, and the largest elements of $G_{qr}$ identify relationships absent from the adjacency matrix, including one pair that later became a direct hyperlink after the snapshot date.
Load-bearing premise
The rankings assume that the 237 philosophers chosen from a French Wikipedia list, and then filtered to those with articles in all nine editions, fairly represent philosophical importance in each language; if that selection favors Western figures, the Western dominance and several cross-edition comparisons are artifacts of selection rather than properties of Wikipedia's knowledge network.
Editorial extensions
If this is right
- If the central claim holds, Wikipedia's philosophical knowledge is organized around thinkers as citation targets, not around doctrines as starting points.
- Language-specific top-ten lists imply that each Wikipedia edition encodes a distinct cultural memory of philosophy, with figures like Marx in Russian, Confucius in Chinese, and Avicenna in Arabic rising locally.
- The weak correlation with specialized encyclopedias means that societal influence and scholarly canon are genuinely different ranking principles, not noisy versions of one another.
- Reduced Google matrix analysis can surface candidate missing links in knowledge networks, as in the Melissus–Xenophanes and Leucippus–Parmenides cases in the English edition.
- The later appearance of a direct Pythagoras-to-Empedocles hyperlink suggests such hidden links can anticipate connections that editors subsequently add.
Reading between the lines
- One step beyond the paper: the Western-only top 38 should be tested against language-specific seed lists before being read as a fact about philosophical importance, because the all-nine-editions filter may itself select for Western canonization.
- The hidden links are network facts, not historical proofs; they become historical claims only when paired with external evidence such as the pseudo-Aristotelian treatise or teacher–student traditions.
- The same $G_{qr}$ pipeline could be applied to non-Western philosophical traditions or to scientists and artists, with the existing results providing a baseline for whether hidden links reproduce known intellectual lineages.
- A natural robustness test is to recompute $G_{qr}$ with a different damping factor or a later Wikipedia dump; stable hidden links would strengthen the case that they reflect structure rather than one snapshot's accidents.

A structured set of objections, weighed in public.
Referee Report
Summary. The paper analyzes Wikipedia's knowledge network by computing PageRank and CheiRank for 237 philosopher articles across nine language editions (Arabic, Chinese, English, French, German, Japanese, Portuguese, Russian, Spanish) using May 2017 snapshots, aggregates the rankings with a Theta-score, compares the results with the Stanford Encyclopedia of Philosophy and the Internet Encyclopedia of Philosophy, and applies the reduced Google matrix to a subnetwork of 21 Presocratic philosophers in the English edition to uncover hidden links. The main findings are that Aristotle and Plato occupy the top positions in most editions, that Western philosophers dominate the top of the combined ranking, that philosopher articles act more as reference hubs than as foundational seeds, and that hidden links such as [Melissus of Samos → Xenophanes] and [Leucippus → Parmenides] can be interpreted as intellectual relationships. The paper also reports an out-of-sample validation in which a predicted hidden link [Pythagoras → Empedocles] later became a direct hyperlink.
Significance. If the results hold, the paper provides a scalable method for quantifying cultural influence in Wikipedia across languages and demonstrates that the reduced Google matrix can reveal latent historical connections in a knowledge network. The strengths include the use of standard Google matrix methods, an explicit definition of the Theta-score, a clear presentation of the PageRank-CheiRank plane, and a concrete out-of-sample validation of one hidden link. The novelty lies in applying these techniques to philosophers and the Presocratic subnetwork, and the work connects network analysis with the history of philosophy. However, the significance is currently limited by concerns about sample selection and reproducibility, which need to be addressed before the conclusions can be fully accepted.
major comments (4)
- [Section 2 / Section 4 (Table 2)] The construction of the 237-philosopher sample from a single French Wikipedia list intersected with the requirement of dedicated articles in all nine editions introduces a selection bias that is not addressed. This filter enriches for figures already prominent in a Western/French encyclopedic tradition, so the claims that only Western philosophers occupy the first 38 Theta-score positions and that philosophers are "reference hubs" rather than "foundational seeds" may reflect sample construction rather than properties of the Wikipedia knowledge network. The paper should demonstrate robustness by using an independent source list or by testing the sensitivity of the Western-dominance and hub-versus-foundation conclusions to the inclusion criterion.
- [Declarations (Availability of data and material)] The data availability statement promises a DOI and a repository but provides no actual dataset, selection script, or reduced Google matrix code. Because the central results depend on the exact list of 237 philosophers and the 2017 Wikipedia dumps, the absence of these materials prevents independent replication and verification of the selection procedure. The paper should either provide the data and scripts or clearly state where they will be made available before publication.
- [Section 4 (The Presocratics in Wikipedia)] The interpretation of Gqr hidden links relies on an unvalidated assumption that a direct link present in one similar subnetwork but absent in another should appear as a short indirect path in the latter. The two supporting examples ([Leucippus → Parmenides] and [Pythagoras → Empedocles]) are anecdotal; the paper does not systematically test this assumption by comparing Gqr values across the nine editions or against a null model. Without such a test, the claim that hidden links correspond to intellectual relationships remains speculative. A systematic validation would strengthen the paper considerably.
- [Section 3, Eq. (1)] The analysis uses the standard damping factor alpha = 0.85, but no sensitivity test is reported. Since the reduced Google matrix decomposition and the rank positions may depend on alpha, the paper should show that the main conclusions (e.g., the top 10 lists and the dominant hidden links) are stable for other reasonable values of alpha, such as alpha = 0.5 or alpha = 0.9.
minor comments (5)
- [Table 2] Table 2 contains repeated rank numbers (e.g., two entries at rank 86 and two at rank 126) with no explicit tie-breaking rule; please state whether ties are allowed and how they affect the "first 38 positions" count.
- [Section 3, Eq. (7)] The text says the sum is performed over the N(N-1)/2 pairs of items, but the formula's normalization and the statement that each term equals 2 on disagreement imply a sum over unordered pairs; the description should be clarified to avoid confusion.
- [Section 4, first paragraph] The sentence "Aristotle ranks first, followed by Plato, with the exceptions of the Russian and Chinese editions" is imprecise; Aristotle is first in all editions, and it is Plato's second-place position that varies. Please rephrase for clarity.
- [Section 2] The SEP and IEP data were accessed in November 2019, while the Wikipedia snapshots are from May 2017; please state whether this temporal mismatch could affect the comparisons and whether the lists of philosophers were adjusted accordingly.
- [Figure 3] The legend for the Presocratic philosophers uses colored markers that may be difficult to distinguish in grayscale; consider using distinct symbols instead of colors alone.
Circularity Check
No significant circularity: the rankings and hidden links are computed directly from Wikipedia link structure via explicit formulas; the main substantive concern is sample representativeness, not circular derivation.
full rationale
The paper's load-bearing results are all computed from the Wikipedia adjacency matrices through explicit formulas: PageRank/CheiRank via Eq. (1), the Θ-score via Eq. (6), Kendall distances via Eq. (7), and the reduced Google matrix hidden-link weights via Eqs. (4)-(5). No parameter is fitted from the conclusion it is used to support; α=0.85 is the standard PageRank damping value, and the 21-Presocratic set is fixed before the Gqr calculation. The Θ-score is an explicit average of the nine edition ranks, and the paper itself notes that it naturally correlates with those rankings ('Of course'), so it is an aggregation rather than a prediction. The reduced Google matrix formalism is cited to refs. [27,28]; although one coauthor (Lages) appears on [28], the formalism is a mathematical identity with independent applications (including biological networks in [28]), and the paper's own out-of-sample check—the [Pythagoras→Empedocles] hidden link that later became a direct hyperlink—supports the method's ability to identify missing links. The main substantive weakness is sample representativeness: the 237 philosophers come from a French Wikipedia list and an all-nine-editions filter, so the Western-dominance observation in Section 4 may be partly an artifact of selection. That is a selection-bias/external-validity concern, not circular reasoning, because the rankings are not constructed to enforce that outcome. No derivation step reduces by construction to its own input.
Assumptions & free parameters
free parameters (1)
- Damping factor alpha =
0.85
assumptions (4)
- domain assumption The damping factor alpha = 0.85 is fixed as in refs [8,9].
- standard math PageRank and CheiRank steady states exist and are unique.
- standard math The decomposition GR = Grr + Gpr + Gqr separates direct, already-known, and hidden transitions.
- ad hoc to paper A missing direct link in one subnetwork should manifest as a short indirect path in another similar subnetwork.

We explore the influence and interconnectivity of philosophical thinkers within the Wikipedia knowledge network. Using a dataset of 237 articles dedicated to philosophers across nine different language editions (Arabic, Chinese, English, French, German, Japanese, Portuguese, Russian, and Spanish), we apply the PageRank and CheiRank algorithms to analyze their relative ranking and influence in each linguistic context. Furthermore, we compare our results with entries from the Stanford Encyclopedia of Philosophy and the Internet Encyclopedia of Philosophy, providing insight into the differences between general knowledge networks like Wikipedia and specialized philosophical databases. A key focus of our analysis is the sub-network of 21 presocratic philosophers, grouped into four traditional schools: Italic (Pythagorean + Eleatic), Ionian, Abderian (Atomist), and Sophist. Using the reduced Google matrix method, we uncover both direct and hidden links between these early thinkers, offering new perspectives on their intellectual relationships and influence within the Western philosophical tradition.
