I believe in some sorts of magic. There is a very important difference between arcane magic and silly conjuring tricks.
There are heaps of magicians who are just decieving the audience in some way but there are also powerful mages and sorcerers who I admire for their talents.
Unlike some people, I do not think that science and magic are mutually exclusive and I think of the the witch doctor as a powerful Lihzahrd who has a knowledge of both science and magic and uses them to his advantage. Personally I prefer the straightforwardness of science to the confusing nature of magic but that is, of course, just my opinion.
