This is the article I mentioned in an earlier heated discussion over global warming.
The author hypothesizes a Newtonian vs. Einsteinian paradigm for science. One, he says, is cautiously empirical; the other, freely theory- and model-based.
He quotes Einstein, who insists (contra Kant, I think) that "theories are 'free creations of the human mind.'"
The article is, I think, worth noting, but those better versed in the philosophy of science should have the final say.
