A regular reader of the blog, Pete White (Cornell University), has called my attention to The Interrogative Mood: A Novel? (Ecco, 2009) by Padgett Powell (Depart. of English, University of Florida). I quote White:
"The book consists entirely of 164 pages of questions ranging from the mundane to the profound. A blurb by the writer Richard Ford says it is 'important-feeling in a way you can't quite describe but don't need to'. That statement has a Pyrrhonian feel to it, as does the sensation of reading the book, which comes to no conclusion, could have gone on indefinitely, and raises the problem of the criterion on every page. In my view, it shows rather than tells, an approach that seems very much in the spirit of Pyrrhonism."
