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.
I bet this sounds like a dream to at least 20% of folks here. I'd love to read about your transition, how does it feel after a while - that would be amazing HN submission. Good luck!
