I just think you're trolling me at this point. And quite frankly annoying me. I answered it, and if I have to explain it again, so be it.
"If the objects are more real than the shadows; how do we know there is not something more real than the objects we see? Is there an ultimate reality?"
Let's break it into two parts. - If the objects are more real than the shadows; how do we know there is not something more real than the objects we see? - How do we know there is not something more real. We carry out experiments to find out. Look at the Large Hadron Collider. It's currently doing work to find out what we don't know.
- Is there an ultimate reality? - Seeing as how we have no discovered it yet. No there isn't.
