Naturalism Naturalism is a literary movement that began in the late nineteenth century. It embraced determinism, detachment, scientific objectivism, and social commentary. The movement largely traces to the theories of French author Émile Zola. In philosophy, It is the idea or belief that only natural laws and forces, as opposed to supernatural or spiritual ones, operate in the universe. A central thought in ontological naturalism is that all spatiotemporal entities must be identical to or metaphysically constituted by physical entities. Naturalism, in philosophy, a theory that relates the scientific method to philosophy by affirming that all beings and events in the universe are natural. Consequently, all knowledge of the universe falls within the pale of scientific investigation. Naturalism is the idea or belief that only natural laws and forces operate in the universe. Adherents of naturalism assert that natural laws are the only rules that govern the structure and behavior of the natural world and that the changing universe is at every stage a product of these laws. Therefore, the following statements would be associated with a naturalistic stance:- Museums and Zoos orient man to learn about nature. Life is ultimately governed by the laws of nature. Sciences are the gateways of learning.
