What if the nature of our reality is non-physical
And how would we ever know that? I replied to your post, but it seems quite silly to me. The examples given of "non-physical" things are clearly physical to me, based on the readings and lectures I've seen.
We come to discover the unknown/invisible (presently non-physical) via its effects by the use of reason (anything that affects our reality - if it doesn't, is it "real"?).
