What is the relation between naturalism and the natural law theory?
Natural law (Britannica):
natural law, in philosophy, system of right or justice held to be common to all humans and derived from nature rather than from the rules of society, or positive law.
In philosophy, naturalism is the idea or belief that only natural laws and forces (as opposed to supernatural ones) operate in the universe.
I feel the two are extremely compatible, to the point that natural law is naturalism as applied to the philosophy of law.
As a point of fact, are advocates of naturalism also advocates of the natural law, and vice versa?
