> My guess is that contemporary 'rationalism' doesn't actually descend from any explicit philosophical tradition, just because if you read an introductory philosophy book, you'd not join a group with that name combined with their ethos.

It definitely doesn't. The community started in almost complete ignorance of philosophy in general and that philosophy had already covered everything they were trying to.

I'm pretty sure they meant "rationalism" comes from analytic philosophy, which I don't think it does although now at least they've realized it exists. Actual rationalism predates both by approximately three centuries.
