The Big Study-- "Do you believe in Miracles?" For me, the question would be: Do you know what you're talking about? The topic has been a masterpiece of human non-thought [in most quarters] and many people think that this is inevitably so. I, probably foolishly, don't think that non-thought is the way to go, even on this subject. I particularly don't want it to slide into the "Well, it's just a mystery" category, because my intuition feels that it is central to the understanding of many types of anomalies. So, "Devil take the Hindmost", here's a try at this.
Let's begin with something non-philosophical: Lourdes, one of the poster-children of the concept of "miracles". [In the interest of disclosure, I am a Catholic]. Here's the background: the Marian apparitions took place in 1858. Claims of miraculous cures began almost immediately. Despite what many people think, the Church is not keen on modern miracles, and rather fears them as wild-cards that occur outside the jurisdiction of the hierarchy, and sources of potentially high embarrassment, if they turn out to be bogus. Because this case was immediately so "public" and sensational [newspapers of the day were screaming headlines about the newest cure], the Church decided to try to protect itself by initiating a "Medical Bureau" composed of professional people [deliberately open to non-Catholics] to evaluate alleged cures.
