Metaphysics & Reality

On what basis can we say that a non physical “thing” exists? Are there properties of the universe which cannot be reduced to 4th dimensional space? If so, are those elements epiphenomenal to physical elements, or vice versa? Or, is there a duality to reality in which both the physical and the metaphysical exist as an eternal yin yang, neither having created the other?

For reference:

You could probaly ask the same questions of a PHYSICAL thing!

Answer away. I’m I treated to hear why you would doubt the existence of physical properties, and what kind of epistemology supports your worldview

Bump. No one thinks about philosophy on this level?
