James Hutton — Scottish Scientist born on June 03, 1726, died on March 26, 1797

James Hutton FRSE (/ˈhʌtən/; 3 June 1726 OS (14 June 1726 NS) – 26 March 1797) was a Scottish geologist, physician, chemical manufacturer, naturalist, and experimental agriculturalist. He originated the theory of uniformitarianism—a fundamental principle of geology—which explains the features of the Earth's crust by means of natural processes over geologic time. Hutton's work established geology as a proper science, and thus he is often referred to as the "Father of Modern Geology"... (wikipedia)

The past history of our globe must be explained by what can be seen to be happening now. No powers are to be employed that are not natural to the globe, no action to be admitted except those of which we know the principle.
What more can we require? Nothing but time.
