Loren Eiseley stated (Loren Eiseley: Darwin’s Century: Evolution and the Men who Discovered It, Doubleday, Anchor, New York (1961)):
“The philosophy of experimental science. . .began its discoveries and made use of its methods in the faith, not the knowledge, that it was dealing with a rational universe controlled by a creator who did not act upon whim nor interfere with the forces He had set in operation. . . It is surely one of the curious paradoxes of history that science, which professionally has little to do with faith, owes its origins to an act of faith that the universe can be rationally interpreted, and that science today is sustained by that assumption.”
Who was Loren Eiseley? From Wikipedia:
Loren Eiseley (September 3, 1907 – July 9, 1977) was an American anthropologist, educator, philosopher, and natural science writer, who taught and published books from the 1950s through the 1970s. During this period he received more than 36 honorary degrees and was a fellow of many distinguished professional societies. At his death, he was Benjamin Franklin Professor of Anthropology and History of Science at the University of Pennsylvania.
He was noted as a “scholar and writer of imagination and grace,” which gained him a reputation and a record of accomplishment far beyond the campus where he taught for 30 years. Publishers Weekly referred to him as “the modern Thoreau.” In the broad scope of his many writings he reflected upon such diverse topics as the mind of Sir Francis Bacon, the prehistoric origins of man, and the contributions of Charles Darwin.
