A while back I was blogging through Alistair McGrath’s trilogy on A Scientific Theology. I largely gave up on that project – they were difficult books to follow, and I didn’t feel I was gaining much for my effort. But one thing that surprised me about McGrath was that he was very accepting of the social sciences, and felt that while different, they were as truly sciences as Biology or Physics. Many physicists, I know, are not so generous in their thinking, and here is one famous physicist offering his opinion. Feynman’s big point seems to be that he has learned just how difficult it is to reach a point where you can really say, with certainty, that you know something, and the social sciences don’t often reach that point.
