“Art: a celebration of beauty and truth.”
Art isn’t always about beauty and truth is often ugly.
Beauty is one of the great Catholic virtues.
How does one find art in ugliness? It doesn't take any kind of talent to create chaos or horror. I suppose one could see beauty in just about anything (Nancy Pelosi is married, after all). But that defeats the argument that the subject is "ugly."
And if, as Shelly says, Truth is Beauty and Beauty Truth, then even the "ugly" Truth is beautiful, in its own way.
It may be torturing the logic (or at least the semantics) but I'm convinced that for it to be art, it has to have some element of Beauty.
