Reminds me of Wilfrid Sellars: “The aim of philosophy, abstractly formulated, is to understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term”.

"Hanging together" doesn't impose as many assumptions as "having specific foundation". It's a very distinct philosophical stance to assume that any kind of human knowledge has a specific foundation, and a naive one at that.
