Uniformitarianism

Geology

The assumption that the same natural laws and processes that operate in the present have always operated in the past and apply everywhere in the universe. James Hutton proposed it in 1785, and Charles Lyell's Principles of Geology carried it to a wide readership from 1830, replacing catastrophist explanations of Earth's history with the patient accumulation of ordinary processes over deep time. It is the working assumption underneath most of modern geology.
