An interview excerpt:
BB: While in the midst of getting pummeled by Captain Marvel, Superman realizes that he understands the true nature of "magic". I am finding it difficult to understand the explanation of "magic" as spoken through the mouth of Clark. Could you verbalize in a way that may help me and other readers better grasp your thoughts? You seem to be saying that is more supra-rational rather than irrational in nature. Is this an accurate observation?
ES!M: Yeah, that's accurate. I'm not sure I can do better than that. I believe in magic. I have a lot of friends who are stage magicians, but I'm not talking about their type of magic. I'm talking about real magic â€“ Merlin's magic â€“ the kind of magic you conjure up to write stories. It's one of those things you don't define; you just feel. At that moment, after a lifetime of practical, logical, hardheaded pursuit of truth and justice, he realizes what it is. It may elude him too, later on. Who knows?
I have read Kingdom Come and it's novelization and I DO NOT recall Superman having any sort of epiphany about magic while getting hit with Shazam's lightening.
Does anyone know where this occurred?
Believe in his novelization of the Kingdom Come Graphic comic book, he had Cap blast him Many more with magical lightning then in the comic, and in the end, kal was said to really understand the nature of Magic, so was not not being affected by it!
Die to it being so unusually to him, and so anti scientific in understanding it, was able to affect him until he realised what it was all about!
