What was the first metaphysical truth you think I agreed with? Imagination?
You are speaking to another mind. This is a metaphysical entity not made of matter. You are the metaphysical materialist. Unless you can account for the physical matter which makes us mind you have referenced another metaphysical truth. You are corresponding with another mind.Although not a metaphysical entity, logic has a sort of metaphysical nature. I t is in fact an abstract, universal entity, as is reason ( the application of laws of the logic), numbers, sets, and beauty, objective morality, and mind.
Unless you can account for these immaterial entities with matter, I am afraid your commitment to materialism exceeds your devotion to Truth. If you can epistemically account for these entities, and other universal abstract entities, please share it with me. I really do want to know the answer.
