I mumbled briefly about Positivism last week, alluding to its potential as a fuel for hubris. No philosophy is the "cause" of human evil and destructiveness, but Human Nature is. Pure rationalism (if there is any such thing) is a frightening way to run the world, or to run anything.
This weekend, in timely fashion, I stumbled on a review of Grayling's latest screed against irrationalism by the esteemable John Gray. One quote from the thoughtful review:
Reading Grayling, it is hard to resist the impression that he believes Western civilization would be much improved if it did not include the Judeo-Christian inheritance. Absurd as it is, there is nothing new in such a claim. It is one of the most venerable clichés of Enlightenment thinking, and Ideas that Matter is a compendium of such dated prejudices. When Grayling condemns religion on the grounds that “a theory that explains everything, and can be falsified by nothing, is empty,” he takes for granted that religions are primitive theories, now rendered obsolete by science.
