New essay: Expressive power, not ontology
There is a new essay on the site — Expressive power, not ontology — that takes on the first question almost everyone asks about the A=1 lattice: is this what the universe is actually made of?
The essay argues that question is not well-posed — there is no view from nowhere against which to score the lattice against reality-in-itself — and that nothing is lost by declining to ask it. What can be asked instead is whether the lattice is empirically adequate and internally consistent: whether it saves the phenomena and coheres. That’s the standing position of a respectable tradition (van Fraassen, Kant), and it’s the one the program already adopts in its Statement of Intent.
Two traps get named. The first is mistaking the lattice for theology: unlike “does God exist,” the lattice keeps falsifiable predictions — it can be caught out by an experiment, which a metaphysical question cannot. The second, opposite trap is more interesting — conceding “one paradigm, not the truth” and then sliding to “so any alternative is just as good.” Underdetermination lets rivals exist; it does not make them equal. Above the threshold of adequacy, theories are ranked by economy, unification, scope, and fertility — and that is exactly where the lattice stakes its claim: look how much falls out of a single axiom.
The piece is deliberate about its own honesty: every generativity example it cites is a Proven row in the claim map, and the predictions it leans on are flagged as still untested. Conceding “not the truth” costs the program nothing. The slogan geometry forces physics is a claim about what the geometry entails — not about what the universe is.
