What he says about having magic not being cosmic forces and elements and colors, but the magic of helping people is *true*.
A witch may not be involved but a witch is always responsible.
A witch has to use headology. And headology nine times out of ten will get the job done.
(Mr. Pratchett, if you're reading this, thank you. I don't think anyone else could have said it better.)
"Because she likes people," said the witch, striding ahead. She cares about 'em. Even the stupid, mean, drooling ones, the mothers with the runny babies and no sense, the feckless and the silly and the fools who treat her like some sort of servant. Now that's what I call magic--seein' all that, dealin' with all that and still goin' on. It's sittin' up all night with some poor old man who's leavin' the world, takin away such pain as you can, comfortin' their terror, seein' em safely on their way, then cleanin' 'em up, layin' 'em out, making 'em neat for the funeral and helpin' the weeping widow strip the bed and wash the sheets, which is, let me tell you no errand for the fainthearted--and stayin' up the next night to watch over the coffin before the funeral and then going home and sitting down for five minutes before some shouting, angry man comes bangin' on your door 'cuz his wife's having difficulties givin' birth to their first child and the midwife's at her wits' end..and getting up and fetching your bag and goin' out again...We all do that, in our own way, and she does it better'n me if I was to put my hand on my heart. That is the root and heart and soul and center of witchcraft, that is. The soul and center!"
