An idea is Panfaith's comparison instrument: a shared
vocabulary that lets one faith's claims be matched against every
other's.
An entry never sums up a religion. It marks one place where
faiths can meet. Two faiths carrying grace have agreed about a
word, not about a doctrine — open the entry and their own phrasings
sit side by side, disagreements included.
The shelves are ours, not theirs. Six groupings, plus new
arrivals for anything the shelves have not absorbed yet. No tradition
organises itself this way; the shelves exist so 58
entries can be scanned rather than scrolled — and the Web view is
where you can watch them fail, because the clusters the corpus makes
are not the drawers we put things in.
A line in the Web is company, not agreement. Two ideas are
joined when the faiths holding one are disproportionately the faiths
holding the other — at least three of them, and only where that
happens far more often than chance would explain. The multiplier on
a pair is exactly that: faiths holding both, divided by how many
would if holding one told you nothing about the other. Plain overlap
would join everything to ritual, which is a picture of how
common ritual is and not of how anything relates. And none of it
says two faiths agree — two traditions can hold grace and
mean irreconcilable things by it.
Reach counts families, not followers. The third view bands
each idea by how many separate roots of the tree hold it. That is the
only measure here that means anything about travel: sibling
denominations sharing an idea inherited it, while two unrelated roots
holding the same thing is the coincidence this whole site exists to
show you. Neither band is a rank — an idea held inside one family is
not a lesser idea, it is a more particular one.
The faith count is what Panfaith has tagged. It counts
claims recorded on this site, not scholarly consensus about who
believes what — a thinly written faith carries fewer ideas than a
well written one, and that is a fact about our backlog rather than
about the religion.
