Paglia gives no indication yet that she is poised to jump the shark.
Here are some comments by Clive James of The New York Times:
One measure of her quality as a commentator is that those two subjects are not in the reverse order. In view of her wide knowledge, her expressive gifts, her crackling personality and the inherent credibility problems posed by looking too much at her ease on top of a pair of Jimmy Choos, it is remarkable how good Paglia can be at not putting herself first. From this book you could doubt several aspects of her taste in poetry. But you couldn't doubt her love of it. She is humble enough to be enthralled by it; enthralled enough to be inspired; and inspired enough to write the sinuous and finely shaded prose that proves how a single poem can get the whole of her attention.... Students grown wary of pabulum might relish the nitty-gritty.
