From David Wheeler at the Chronicle of Higher Education blog:
There’s a new bully on the intellectual block, shoving scholars around. Lots of them are caving into the threats. The bully’s name is “scientism,” the belief that science has a monopoly on all real knowledge. All other knowledge, scientism asserts, is simply opinion, irrationality, or utter nonsense.
That was the perspective Ian Hutchinson, professor of nuclear science and engineering at the Massachusetts Institute of Technology, offered at an event titled “Can Science Explain Everything?” at the American Association for the Advancement of Science this week. . . .
Hutchinson, theauthor of Monopolizing Knowledge: A Scientist Refutes Religion-Denying, Reason-Destroying Scientism, said that science is in the middle of confrontation with religious faith and with many other forms of belief. He is proud of science’s achievements thus far. But he thinks that, in part because of its overwhelming success, members of other disciplines, seeking the authority that science has, try to make themselves out to be scientists. An alternative course, he suggests, would be for scholars such as sociologists and political scientists to firmly declare that they have ways of building knowledge that are simply different from science, not “unscientific.”
Science has two key elements, reproducibility and clarity, Hutchinson said. Reproducibility means essentially that an experiment done in one place by one person can be repeated somewhere else by someone else. Clarity refers to the unambiguous nature of science’s measurements, descriptions, and classifications. History is an example of a discipline that has produced real knowledge that is not scientific knowledge, he said. History at its best is based on facts, but historians cannot reproduce Henry VIII’s exploits to find out if accounts of them are true.
Mr. Hutchinson listed other phenomena that may be “true” but that he believes are outside of science’s scope: the beauty of a sunset, the justice of a verdict, or the terror of a war. Many humans may share similar perceptions of these phenomenon but the basis of those perceptions will lack clarity. “Ambiguity is an intrinsic part of these things,” he said.Where, exactly, does God fit into this picture? Mr. Hutchinson says that while the universe has physical laws, God may be behind them. Science would be helpless to detect an act of God that violates the laws of physics since it would not be reproducible. Scientists should have no problem being religious, he said.
Enter Lisa Randall, a woman with an astonishing range of achievements from a libretto for an opera to experiments at the Large Hadron Collider, in Geneva. She studies cosmology and theoretical particle physics and is the author of “Knocking on Heaven’s Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World.”
While polite in tone, Ms. Randall said the term “scientism” was embarrassing and an act of name calling, at a time when the discussion about tackling the world’s problems needs to be elevated. “It shouldn’t be embarrassing or quaint to be earnest about facts or logic,” she said. And, she added “Why do politicians feel comfortable talking about God and religion and not about science and mathematics?”
Art is important she said, but it ultimately operates through the filter of human perceptions and emotions. Religion, she said, is also a human phenomenon that serves social needs. “If you say it makes me happy or helps me live my life, I’m not going to stop you,” she said.
But, she said, religion is different to different people. Scientists, while they have their petty fights, are ultimately able to create knowledge they can agree on.
In audience questions after the two talks, one person cut to the chase and demanded “yes” or “no” answers to the evening’s challenge: “Can science explain everything?”
“No,” said Mr. Hutchinson.
“We don’t know,” said Ms. Randall.
