Magic is just a mix of highly theoretical and poorly explained influence, memes, and metaphysics.
The greatest sect of magic is memetics. It is useful to perceive reality as a series of symbols that extend in power based on their popularity, strength of belief in them by others, and how fundamental they are to the universe's coding.
But don't bother treating it as magic. Nobody has ever managed to actually achieve an act of magic you couldn't just as easily call science. True magic, as in that which cannot be sufficiently explained by science yet clearly occurs in a way which transcends normal science, has yet to be realized save for metaphysics on tiny shit we have no reason to believe we can control without technology.
Magic is one disappointment after the other. It's more of a self-help style of studying more-bullshit-than-usual philosophy and creative concepts. I can guarantee it's been discovered though; in an alternate universe far from this one.
