But the distinction between "natural" and "supernatural" is something else, isn't it?
Perhaps it's better to think of it in three categories:
1. Natural: that which occurs without agency.
2. Unnatural: that which occurs through agents that exist within the observable world.
3. Supernatural: that which occurs through agents that do not exist within the observable world.[/quote]
Yes. But you seemed to be misreading the purpose of the book example. It was to show how one can rightfully conclude the role of non-natural causes. (This fits within your definitions.) However, when you said
Quote:
If I saw that the book had moved I would assume it had been moved by a human being, who is part of the natural world. So I would clearly consider its movement a "natural process".
You are clearly conflating the first two categories. Of course, if you are a hardcore determinist, then the second category is empty and this would explain the disagreement of concepts (and we're not speaking the same language).

But as soon as you even start talking about a "phenomenon", you've necessitated it to have at least some kind of properties, otherwise it's just nothing.
Your description of "property" implies some form of determinism. Given conditions X you will see result Y. This notion is not sensible in the context of "agency." When you consider the collection of man-made constructions (buildings, vehicles, whatever), you cannot classify them all by saying that they have property X, unless property X is "made by man."

I just don't really understand what the difference is between describing an inexplicable event as being caused by some undefinable "agent", and it simply being caused by nothing.
What do you mean by 'caused by nothing'?

If we define supernatural events or miracles simply as those events for which there is no possible explanation, well that's fine, but I don't see any meaning in starting to talk about unknowable "external" causations for those events.
I would reject that definition because it doesn't make sense. Nobody ever claimed that miracles have "no possible explanation." By the definition that has been discussed:

For this discussion, I would take the much more plain definition, which is a supernatural being (God) superseding upon the natural world. Under this definition, there is a role of agency that is not present in the preceding definitions, and requires the intervention of something from outside the natural world (ie, the physical universe is not a closed system).
