How does this sound as a simple definition of Magic:
An act by a practitioner causing a result that is not explainable by science.
This is not to say that magic can never eventually be explained by science, but just that we can’t explain it today.
Levitating a quarter would fit the bill, improving your mood or psyche would not. From all of the various posts I’ve read so far on this subject, none of the magic(k) practitioners have personally claimed to do anything not explainable by science, and I doubt any will.
The reality is that science knows a great deal about our universe, magic spells and rituals are not likely to tap into any currently unknown forces or physical effects. Most likely, any new discoveries will occur in a lab, bypassing any possible magical connotation. Some advances long ago may have been considered magic at the time, I’m thinking herbal medicine type of stuff here, but are now known and well defined by science.
Many of these posts imply that scientists are closed minded about this subject, not true, Believe me, if someone could produce a verifiable result that is unexplainable by science, the scientific community would be overjoyed. They would have something completely new and interesting to poke at and find out how it works, they would welcome the opportunity.
Nobody is going to claim in this thread that they can do anything not completely explainable by science, because they will never be able to back it up. If practicing magic(k) makes them happy, and fulfills their lives, wonderful, don’t let any of us stop you. Only, let’s not claim that your powers defy science, unless of course, you’re willing to back it up.
