From Richard Dawkins, Cyclops of Science:
The only thing worse than a pugnacious atheist is a pugnacious atheist who has a fetish for scientism. In that light, Dawkins’ bemoaning of childhood fiction actually makes sense. Devoting an inordinate amount of his life’s work to empirics makes any man coarse. Facts are blunt and stark, while imagination can be bright and stirring. The greatest works of art and architecture produced by man weren’t the product of cold calculation. They were inspired by a volition that doesn’t take cues from controlled laboratory experiments.
Here's a good piece on scientism as a superstition.
