Muggles really have some good ideas about magic, in fact. Though they don't call it magic. They still have this notion that there's a hard division between 'magic' and 'science.' Which I guess they'd have to since they can muck around with one and can't touch the other, and usually don't notice if they're touched by it or blame it on something else (often science). Instead, they dream up these elaborate machines to do things that really require magical spells. I almost think of it as solidifying or visualising the spell, if that makes sense, in chemistry or circuitry or gears. It's not a bad way to think about things, since spells are usually more structured and more complicated than you would guess to see one in the moment it's actually cast.
I've been going to that auror meeting thing about the philosophy of magic, or ethics of defense, or whatever it is that
