Mortimer Adler

Adler's Syntopicon indexed the Western canon against 102 recurring “great ideas” — Quality, Change, Cause, Necessity, and so on. Lens uses a working subset of these as a neutral vocabulary for what a page is actually talking about, so the read doesn't depend on the brand's own coined terms. Each cluster groups the words a page uses for one idea; a tightly-held idea names itself with one anchor word, while a scattered idea spreads across many near-synonyms. The Ideas output shows which ideas a brand leans on and how consistently — the raw material for the consolidation and consistency moves.
