Is there any way to demonstrate metaphysical phenomena that are not the product of the physical world? After all, if the one property of the metaphysical that we can define is that it is the product of the physical world, then that would necessarily apply to all metaphysical phenomena until shown otherwise.
This is a good question. Because now we are legitimizing all metaphysical phenomena since it comes from the physical brain. Or not.
But if not, why? Shouldn't the brain be sufficient to legitimize all thoughts and emotions?
