Hehe, I don't wanna bore you but here's Kant if you're interested :): The noumenal is the idea that's there's an objective world free from our perceptions. The phenomenal is the idea that the world is created by our minds, that there's categories like time, space etc which our minds shape the world with, relativity in other words. The noumenal does not exist and is a persistant problem with the mind. On numbers :P here's Eddington*, "We used to think that if we knew one, we knew two, because one and one are two. We are finding that we must learn a great deal more about 'and'.” Even mathematics works on values and categories our mind creates. So economics isn't noumenal, it's a value, that science and art aren't actually that far different from each other as we think :) I'm convinced but I don't think this post is the greatest convincer lol I do like this Eddington quote: "Not only is the universe stranger than we imagine, it is stranger than we can imagine." I love that one :) *he organized two expeditions to observe a solar eclipse in 1919 to make the first empirical test of Einstein’s theory.
