"Anyway, it sounds absolutely ridiculous, I am aware of that –" he said self-deprecatingly. "– but science fiction novels were the catalyst that brought me to the eventual realization that Muggles aren't lesser because of their lack of magic. Because they're not lesser, just different – wizards may have magic, but Muggles have science and technology. And where technology can only advance as the understanding of the science behind it develops, magic can't, not in the same way. Or if it can, the Wizarding World has lost the knowledge of how to advance it to any meaningful degree. So Muggles don't need magic."
