For example the way psychology managed to squeeze into the liberal arts and overlap religion; that sure changed how people compartmentalized.
You didn't have a large medical establishment working alongside the church to address "mental illness" (Foucault talks about all this of course).
When I studied Wittgenstein's stuff at Princeton under Rorty et al, I kept bopping back and forth between Philosophy and Religion departments for classes, yet I think his investigations also fall between Anthropology and Psychology (both still young disciplines in his day -- he wrote about both).
