> Personally, I tend to see fantasy as having a more spiritual atmosphere, more about the magnificent things and creatures in the world. I think using the term "magic" so much without a perfectly clear definition is bound to come up with several debates like this. However, you can't really clearly define magic. Looking in the dictionary, it refers to incantations and such, but that doesn't really capture the essence of it, does it? This is gonna get me a lot of other viewpoints, but I like to think of magic as "that which is impossible being possible".

Here's a theory I think I'll toss in and see what everyone has to say. Science Fiction is set in a world (used generically to mean "setting" without having to say "set in a setting") that is decaying over time, while fantasy is set in a world that's improving. Admittedly, of course, fantasy worlds have their downs and sci-fi worlds have their ups, but the generaly state of one is decay and the other is advance.
