Magic And Goetics. (Sometimes, all the work has already been done in an earlier post.)
How many other meanings are there?
(ii) In one popular meaning and in the Harry Potter series, waving a wand and uttering incantations creates matter and breaks the conservation laws.
(iii) In SM Stirling's Dies The Fire and somtimes on Earth Real, "magic" means Wiccan rituals.
(iv) In James Blish's Black Easter/The Day After Judgment, magic is control of demons which are fallen angels.
(v) The DC universe includes magicians like Zatara, Zatanna, Arion of Atlantis, Merlin, Tim Hunter and John Constantine. The theory is that belief alone is enough to generate supernatural beings and realms and working magic. Kryptonians are vulnerable to magic as to Kryptonite. Many fictions coexist as in Poul Anderson's and Michael Moorcock's multiverses.
An evening of alternative reading usually generates material for a comparative blog post.
