As a literary society, we have long since gotten over our modesties. The literature of addiction, once the exclusive territory of imbalanced, suicidal poets, has now come to dominate the market. We no longer recognize self-indulgence as self-indulgence. The term itself has fallen out of use, relegated mostly to protests from bitter Amazon.com reviewers and the curmudgeons of the weekly book reviews. Stylish women in New York write chatty columns about how much of their paycheck they spent on the latest “must have” designer handbag. The bestseller shelves are flooded with the memoirs of 30-year-old alcoholics.
