Book excerpt: Who is the greatest living essayist writing in English? Unquestionably Joseph Epstein. Epstein is penetrating. He is witty. He has a magic touch with words, that hard to define but immediately recognizable quality called style. Above all, he is impossible to put down. How easy it is today to forget the simple delight of reading for no intended purpose. Each of the 39 pieces in this book is a pure pleasure to read.
