Is the Trick Done?

I thought about what exactly makes the difference. And I think that the example that I like best, although again, not everyone does, is the example of the conjurer. So you can predict quite confidently that the ball isn't there, and there you are, it's vindicated. But that's not what you mean by how is the trick done. What you mean is what has happened to bring about the thing you saw. Yes, yes. The one thing that you actually can't observe is indeed the onething that you're invoking as actually existing and causing the phenomena that you do observe.
