Metaphysical naturalism, also called ontological naturalism and philosophical naturalism is a strong belief in naturalism, a worldview with a philosophical aspect which holds that there is nothing but natural elements, principles, and relations of the kind studied by the natural sciences, i.e., those required to understand our physical environment by mathematical modeling.
Metaphysical naturalism holds that all properties related to consciousness and the mind are reducible to, or supervene upon, nature. Broadly, the corresponding theological perspective is religious naturalism or spiritual naturalism. More specifically, it rejects the supernatural concepts and explanations that are part of many religions.
This is the closest thing I have to a religion.
