What makes a philosophy naturalistic, or even physicalistic? We are inclined to think that traditional Christian theism is supernaturalist view, but what makes something supernatural? Unlike C. S. Lewis, I want my naturalist opponents to tell me what their naturalism excludes. Otherwise, I'm just going to argue that my Christian world-view is just a liberal form of naturalism.
The characteristics of the physical that interest me are the absence of certain critical elements from the basic level of physics: intentionality or aboutness, normativity, subjectivity or perspectivality, and purpose. Would you consider something to be naturalistic if the fundamental-level explanation for its activity were, say, teleological? If something is purposive at the basic level of analysis, could it be naturalistic in any meaningful sense. If yes, then what do we have to include in our explanation in order for us to say "OK, if that's in the basic-level explanation, it's not naturalistic anymore."
