Whenever someone asserts that a scientific question is “settled,” they tell me immediately that they don’t understand the first thing about science. Science is never settled. Science is not a dogmatic body of doctrine. It is an open system of knowledge that establishes probable truths that are subject to continual revision. The entire history of science is one of established theories being overthrown. Astronomers once believed the Sun revolved around the Earth. Naturalists maintained that species were immutable. Geologists thought continental drift was physically impossible. Physicians attempted to cure people by blood-letting. Are we to suppose that the process of history has stopped?
