Naturalism is "the idea or belief that nothing exists beyond the natural world".[1] It is the belief that "the natural world is the whole of reality".[2] The term was first used this way in English in 1750.[3]
It is a kind of philosophy called metaphysical, because it covers everything: "nature is all there is, and all basic truths are truths of nature".[4]
All the things and powers which are commonly called supernatural, such as God, souls or witchcraft do not exist, according to this position.
