The whole existence thing is flawed imo. Does an iron ladder exist? It is just a configuration of elements that are perceived as such. The conception lays on “our” plane but not on the lower. We use a latin word for it, but it is still “our” word. We separate things, not things themselves.
What bugs me in philosophy is that you can read theories and ideas (good ones), but no one asks if base terms are too much human to be important. Is there a school that doesn’t ob/subjectivize “items” and thinks as a whole?
