Here is a review of William T Vollmann’s Poor People by John Cotter, who finds the book worthy:
Poor People remains more a series of interrelated essays than a unified critique. Some of the essays are painfully sad; some are challenging; some, like the story of Gary, the numbers runner in the Philippines who hang-glides, smokes ice, and re-reads David Foster Wallace, are fun to read. Poor People, despite its distance, is a worthy book.
On the other hand, Steve Donoghue is not impressed by Hofstadter’s I am a strange loop; in fact he titles his review A tiny and swattable mind, and concludes it as follows:
… we have I am a Strange Loop, a deeply flawed misfire of a book for which Hofstadter should apologize to the roughly 90 billion beings on Earth who will never read his book, nor even want to.
Take a look — both the reviews make good reading!
