Arthur's Seat was the laboratory of James Hutton. James Hutton 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". In his book, Geography of Genius, Eric Weiner points out the genius of James Hutton in a very nice way: "Most of us look. The genius sees. Hutton noted when something wasn't quite right, didn't fit. Rahter than dismiss such inconguities or explain them away, he investigated further. He asked questions. Why, for instance, was one layer of rocks, called Salisbury Crags, darker than others in the area? What were fish dossils doing on the summit of a mountain?".
