I'm more or less recording this for my own reference, since I have absolutely nothing to add, but Matthew Milliner's been on a roll, writing-wise.
He wrote a blog post called “Beauty and the Barthians,” which explains why, for all the good things to be found in Barth's theology, Barth is a dead end as far as theological aesthetics are concerned. I'm just dipping my toes into Barthian waters now, and I'm really glad that Milliner has already mapped out how Barth relates to Hart, whose book The Beauty of the Infinite I read and enjoyed several years ago.
And then, a few days after showing us a dead end, Milliner points to the more promising paths explored by Jacques Maritain in an article for Public Discourse about “The New Maritainians.” Clearly, I'm going to have to chase down some of the books he's mentioning here.
Really, millinerd.com just keeps getting better and better.
