Biologists explain how organisms adapt to their physical environment, but ideologues also adapt to their social environment. The most fundamental fact about the ideas of the political left is that they do not work. Therefore we should not be surprised to find the left concentrated in institutions where ideas do not have to work in order to survive.The academic world is the natural habitat of half-baked ideas, except for those fields in which there are decisive tests, such as science, mathematics, engineering, medicine – and athletics. In all these fields there comes a time when you must either put up or shut up. Thomas Sowell
