Hey, let's talk about miracles, because that's way more interesting than discussing Aristotle.
The first problem with miracles is how to define the word "miracle". Some definitions make everything into a miracle, including lucky coincidences. Some definitions make miracles impossible. I think we want a definition which allows for miracles, but only after thorough investigation.
Of course, I'm Catholic, and I have been influenced by the Catholic Church, which is very strict when it comes to miracles. Depending on which source you use, only a tenth to a third of all investigated miracles are officially confirmed as miracles.
A bad definition of "miracle" is "an event that cannot be explained". Just because a person cannot explain an event, it does not mean that said event is a miracle. Furthermore, it is often the case that something cannot be explained at the time it happened, but it can be explained later as human knowledge increases. Why, if George Washington was brought back to life today, he would see miracles everywhere: flying machines, self-moving cars, lights which can be controlled by switches!
The famous definition of "miracle" comes from David Hume, who defines a miracle as "a transgression of a law of nature by a particular choice of God". He then goes on to explain that miracles don't exist, and even if they did, it would be impossible to prove it. Imagine a court trial, if you will. On one side, you have the evidence of every human being who ever lived, observing that the laws of nature exist. On the other side, you have a limited group, saying that a law of nature was temporarily broken at one point. It is impossible for the limited group to create solid enough evidence to trump the other side. It's just not going to happen.
Even Jesus Christ, the most famous miracle-worker of all time, was met with skepticism and indifference when he performed miracles.
What do you readers think? Are miracles possible or impossible? If a miracle occurs, is it possible to show that it was caused by God and not some other, unknown cause?
