The Austrian School of Economics is a tiny group of libertarians at war with mainstream economics. They reject even the scientific method that mainstream economists use, preferring to use instead a pre-scientific approach that shuns real-world data and is based purely on logical assumptions. But this is the very method that thousands of religions use when they argue their opposing beliefs, and the fact that the world has thousands of religions proves the fallibility of this approach. Academia has generally ignored the Austrian School, and the only reason it continues to exist is because it is financed by wealthy business donors on the far right. The movement does not exist on its own scholarly merits.
I don't entirely accept that the use of logic is a defining factor in religion - the problem for me is that the initial premise always has to be taken on faith. The argument after that can be entirely logical but still lead to a nonsensical conclusion, which is what I assume Steve Kanga means. It's well worth a read. The summary above sort of confirms my gut reaction set out in the earlier post.
