Naturalism and Materialism are necessarily false

Thoughts exhibit intentionality. Naturalism is the view that all of nature is determined by laws and processes that have no plan, no intentions, at their foundation. Therefore this entails that thoughts cannot literally be identical to a physical process. Since thoughts cannot be derived from physical processes either (i.e they are non-reducible), and thoughts exist, this entails naturalism is false. A fortiori materialism is false too.
