Gunnerkrigg Court 8: Thrown for a Loup

[Lizard Lord]

The best approach I've seen is that magic can be either exploited or explained, but not both.

Suppose you can generate fireballs at will. Your scientist friend comes up with a lot of ways to examine and analyze what's happening. Finally he discovers that all along it was just spontaneous explosions of swamp gas, a complete coincidence. Now you can't generate fireballs at will anymore. Thanks, scientist friend.

That's just it. Magic that can't be explained is thus defined by being something that is explained by not having an explanation. "It just works" is the only explanation. However Zimmy, who doesn't believe in magic, is saying that something that is explained by not having an an explanation isn't magic. So then what, according to her, would be magic? Does Zimmy just define magic as something that doesn't exist?
