Not him but it pretty much is. DC magic is basically a metaphysical force that consciously dislikes being defined or explained. Mages in the setting concoct made-up rules like a bunch of children playing imagination games in order to make magic easier to use and understand. But in response Magic gets annoyed with them and reduces their power in response because they aren't playing the way it wants.
The highest level mages are basically just reality warpers who don't try to explain anything or define magic at all. They literally know as much about how it works as the average civilian on the street watching them casually warp reality does.
