Poetic naturalism is a philosophical approach to naturalism which encourages a variety of ways to talk about the world, using language dependent upon the aspect of reality being discussed. The term was coined by Sean M. Carroll in his book The Big Picture: On the Origins of Life, Meaning, and the Universe Itself to offer richer insight into naturalism, with strategies for agreeing on useful ways of talking about the natural world. It acknowledges that the methods and terms used within one domain may not be coherent with those of another domain, yet both can be considered valid representations of reality.
