Here’s a YouTuber’s take:
The argument is that beautiful and sublime are central to art. They could almost be called the yin and yang of aesthetics, but they’re not entirely opposite to each other. Delight and Awe are not mutually exclusive.
One could make an argument, however, that Low Art seeks delight (beautiful), while High Art, awe (sublime), but that could be a case of stretching the heuristic.
