the.com/naturalism

means The view that nature — physical matter, energy, and natural laws — is all that exists, with no supernatural realm pulling strings behind it.

from From Latin 'natura' (nature, birth, the way things are), itself rooted in 'nasci,' to be born. The '-ism' got bolted on as philosophy's standard way of turning a concept into a creed. The word spent centuries doing double duty — in art and literature it meant depicting life unvarnished, warts and all; in philosophy it came to mean rejecting the supernatural entirely. Both senses share the same instinct: trust what's actually there, skip the embellishment.
