Heat water, and it eventually boils. Oppress the workers more and more and bring on the revolution.
Stephen Jay GouldAs in 1925, creationists are not battling for religion. They have been disowned by leading church men of all persuasions, for they debase religion even more than they misconstrue science. They are a motley collection to be sure, but their core of practical support lies with the evangelical right, and creationism is a mere stalking horse or subsidiary issue in a political program...The enemy is not fundamentalism; it is intolerance. In this case, the intolerance is perverse since it masquerades under the 'liberal' rhetoric of 'equal time'.
Stephen Jay GouldDarwin's principle of natural selection leads to the prediction that the proper way to analyze any evolutionary development is to see the new features as adaptive to environments. And that's a perfectly good principle. The problem is that there are many evolutionary biologists who view everything that happens in evolution as directly evolved for adaptive benefit. And that just doesn't work. Whenever you build a structure for adaptive reasons, the structure is going to exhibit properties that have nothing to do with adaptation. They're just side consequences.
