Then you're not talking about the same thing when you use the word naturalism. Naturalism as the claim I mentioned - there is no God, no eternal soul, no afterlife, and we live in an insentient and purposeless universe - is a metaphysical claim.

If your point is that science dictates our metaphysics, then everything I said in the article applies. You're trying to fit the world to your method. That's just scientism.
