After posting about John Gray's new book "The Silence of Animals" I found this talk that he gave at the Royal Society of Arts in April. There Gray concisely expressed the argument in his book. He explained that he doesn't deny the possibility of instances of progress, because such a statement is immediately, empirically false. Rather, he explained that he doesn't think that the advance of scientific knowledge has any correlation with advances in our ethical and political practices. That is, we could get smarter and smarter, know more and more about the world, and yet the same deep flaws in the human constitution would continue to cause the same ethical calamities to occur over and over again. Below you'll find the thesis of his talk and the video.
Errors in human thought in general, in ethics and politics, in human civilization and culture, are not like errors in science. Errors in science don't usually come back. We won't see an article in Nature saying 'By God, Nostradamus was right.' Whereas the exploded fallacies of a previous generation in human thought more generally, in human culture, like this idea of social evolution, always do come back. And that's why in my book I kind of conclude by saying that if human rationality was really a scientifc theory, if we approached the idea that human beings are even potentially reasonable, rational, and that the increase of knowledge would increase human reasonableness, if we treated that as a scientific theory in a truly critical way, we'd have abandoned it, dumped it, in the trash can of history a long time ago.
