I do think Plato was on to something with the concept that the ideal is more real than the physical. Consider the following.
Everything we know about reality is filtered through our consciousness. Everything about the physical world is interpreted through that lens. It's the only thing we can actually be sure of. I am sure that I'm a conscious being. I'm not completely, totally, 100% sure that I'm not a brain in a vat. I'm 99.9999999% sure, but not absolutely. Or more realistically, there's a small possibility that I'm only dreaming that I'm posting on KF right now. What might that say about the universe we live in? Maybe mind is primary, and matter is secondary.
I don't mean that in a postmodernist way, like human thought literally creates reality or something like that. The physical world is definitely real. Just not quite AS real.
