An atheists guide to reality

[Mystic]

So value is "in your spirit" instead of in your brain; how does that make it any more "real" ?

Well if it's just a concept created in the brain, it has no essence, it's purely conceptual. This value seems to be such that it exists as we imagine it to exist. While in the case of a spirit existing, it's estimating something that is real, and not simply conceptual existence. It's real because there is a reality to it instead of it simply being a concept.
