What exactly does "shared partial interpretation" mean?
shared because we have very similar neural structures and communicate with each others, partial because our knowledge isn't innate, so each has a restricted view of the universe; is it clearer now ?
So you mean "does reality depend on the viewers?"?
That our social constructs somehow have a bearing on what is actually real?
not only social constructs, everything is only "true" to our poor brain notion of truth.
