Instead, we get this from Victor Davis Hanson:
Until 1982 “settled science” decreed that stomach ulcers were a result of bad diet, too much gastric acid, or undue stress. Then Australian scientists Barry Marshall and Robin Warren shocked the medical community with an unlikely thesis: The real culprit for peptic ulcers more often was infection by the Gram-negative bacterium H. pylori, a common but sometimes dangerous agent in the gut that could be treated with antibiotics. The practice of gastroenterology was turned upside down.This somehow leads him to the insight that
In other words, nothing scientific is ever quite settled.which must make it very difficult to get up in the morning. I mean, how does he know the laws of electrostatics are going to provide a firm footing when he puts his foot on the floor, and that he won't sinnnnk right through to the molten core of the Earth? That he's not going to fly off the surface of the planet because, you know, gravity is not ever quite settled? That his car won't start because the laws of thermodynamics were overthrown in the middle of the night?
Some pundits -- Krathhammer, Hansen and the like -- don't understand science in the least. Or how it arrives at the conclusions it does. That is to say, why we know what we know.
They should have to forfeit all the many good things science has provided in their lives -- which is basically everything -- until they understand that the fundamental laws of thermodynamics, quantum mechanics and radiation aren't ever going to change. And why.
They seem to be waiting around for the day when scientists say, "Oops! We were wrong about carbon dioxide all this time -- it really doesn't absord infared radiation. And all objects, like, say, the Earth -- they don't really emit radiation. We guess! Who knows? So go ahead and burn all the fossil fuels you want. Our bad!"
Idiots. (And I mean that sincerely.) Worse: dangerous. History has shown that we ignore science at our peril.
