It was google for like-minded people or tear my hair out in exasperation. The cause: there was a piece in the NY Times about a proof for the existence of God. To simplify, but only a bit, the proof (called the ontological argument) says that if you can conceive of God then God must exist. Which seems the quintessence of a circular argument. My exasperation is that nobody seems to understand the null hypothesis which is one of the fundamental principles of scientific reasoning. Or maybe that people's reasoning hasn't advanced from the witch scene in Monty Python and the Holy Grail.
