Victor J. Luque (2016), Biology & Philosophy 32(1):97–125 (January 2017; online 2016-09-16); preprint on PhilSci-Archive (#12404) — DOI-10.1007/s10539-016-9538-y
Key takeaways
- The Price equation is not a model on its own, as critics say, but a Kuhnian “generalization-sketch” — an abstract, unifying, invariant schema specialised into concrete models — which defuses disputes such as the one over Hamilton’s rule and vindicates the analogy with Newton’s second law.
Seeded from the abstract and a skim, before the reading in NOTE-101. What follows is what the work says about itself.
Luque analyses the Price equation’s role in evolutionary theory. Traditional population-genetic models build in simplifying assumptions to stay tractable, whereas the Price equation starts from assumptions taken to be true and derives the system’s mathematical rules. He argues it is a generalization-sketch whose main job is to give researchers a unifying framework for building specific models, a role it can play because, like other scientific principles, it is abstract, unifying and invariant. Seeing it this way defuses recent disputes about it.
Standing in the record
Filed from the 2026-09-26 sweep of the papers-feed tracker for philosophy: 25 seconds of active reading over 1 session. It was filed Deferred, unread. NOTE-101 is the close reading of 2026-09-26, and it placed the work: Active — worth reading as a clear statement of the generalization-sketch reading of the Price equation and as a map of its extensions up to 2015 (Tables 2–3). The philosophical argument is thin in places, notably the Gödel-based case that it is “not a tautology”, so it should be read as one side of the dispute and not as a settlement of it.
When seeded, before the reading in NOTE-101, the entry gave a priority for a deeper reading: low — brief visit (t = 25 s); a clear single thesis that the skim captures.
What the seeding asked a deeper reading to check (NOTE-101 is that reading):
- Useful for any record discussion of what general equations or identities contribute to a science (the “just a tautology” objection).
- Check how the invariance claim handles the Price equation’s dependence on how populations and ancestor–descendant maps are specified.
- Pairs with the units-of-selection material (LIT-160, LIT-201), where the Price equation underwrites multilevel partitioning.
Access when seeded: Springer and PhilSci-Archive block direct fetches; read the author’s manuscript (22 pp., same title and abstract as the published version) via a SciSpace PDF mirror. PhilSci record metadata (datestamp 2016-09-05) came from a Wayback snapshot; journal dates and pages from Crossref. The published version itself was not read, so small differences are possible.
