Exposure is defended by people who don't truly love magic.
They are cheap,
The poor are, I suppose, "cheap."
and unwilling to pay respect to the people that they should be.
When you purchase a magic product, you aren't paying just for the secret. You're paying respect to the creator.
No sir. I resent that.
Respect is paid through dedication.
The dedication to perform the trick correctly, the dedication to the art of magic.
You can buy all the tricks you want, but if you don't put in dedication, if you don't work hard, and you perform it badly, you are showing a GRAVE disrespect to both the original performer, and the creator.
Anyone can buy a trick. Anyone can learn a trick when it's exposed. The payment of respect comes from the dedication you give it, not from the power of your wallet.
It's not magicians talking among magicians about magic effects.
Well, that goes without saying. If you show how an effect is done to non-magicians, you're essentially performing without any performance whatsoever. As I've said before, a show with tricks and nothing else bastardizes the art of magic.
(That said, some exposure performances CAN have drama and context. Case in point, Penn and Teller's "Blast off." That performance has a message; pretension is stupid.)
I think, even if we don't know the exact mechanism, we all have a basic idea of how Teller's trick "Shadows" works. Even if you know how it works, it doesn't detract from the grim beauty of the routine.
You know how books are written, but that doesn't detract from reading Poe, does it?
Oh, and lastly, don't knock Val Valentino. He's the guy that got me interested in magic.
