A re-post from 2007 -
Paul Davis, author of Cosmic Jackpot: Why Our Universe is Just Right for Life, has an opinion piece in the NYT: Taking Science on Faith. It begins:
Science, we are repeatedly told, is the most reliable form of knowledge about the world because it is based on testable hypotheses. Religion, by contrast, is based on faith. The term “doubting Thomas” well illustrates the difference. In science, a healthy skepticism is a professional necessity, whereas in religion, having belief without evidence is regarded as a virtue.
The problem with this neat separation into “non-overlapping magisteria,” as Stephen Jay Gould described science and religion, is that science has its own faith-based belief system. All science proceeds on the assumption that nature is ordered in a rational and intelligible way. You couldn’t be a scientist if you thought the universe was a meaningless jumble of odds and ends haphazardly juxtaposed. When physicists probe to a deeper level of subatomic structure, or astronomers extend the reach of their instruments, they expect to encounter additional elegant mathematical order. And so far this faith has been justified.
The most refined expression of the rational intelligibility of the cosmos is found in the laws of physics, the fundamental rules on which nature runs. The laws of gravitation and electromagnetism, the laws that regulate the world within the atom, the laws of motion — all are expressed as tidy mathematical relationships. But where do these laws come from? And why do they have the form that they do?
Read the whole thing. Jonah Lehrer at The Frontal Cortex in a piece titled The Faith of Scientists expands on the topic, referring to the ideas of philosopher V.W.O. Quine. A quote:
When Quine came up with his holistic version of knowledge, he also demonstrated that our most necessary scientific principles are actually the least provable. For example, most scientists, when asked what constitutes the starting principles of reality, will probably say something about one of nature's fundamental laws, like gravity or the theory of natural selection. But these are precisely the same things that we will never see directly. (As Gertrude Stein once wrote, "The laws of science are paper laws, they make believe that they do something.")
Read this whole thing too. The notion that the laws of nature have no existence seems obvious, but it turned on a lightbulb for me. The point, as I see it, is not to discredit the scientific method or scientific theorizing, or to glibly equate science with religion: the point is that we must have humility about the depth of our knowledge.
