Seneca wrote "veritas odit moras"-- literally, "truth hates delay." It is a fitting motto for  Arts & Letters Daily, a wonderful website filled with links to dozens of magazines, book reviews, blogs-- in short, one-stop shopping for people with insatiable curiosity.  While thoughtful, erudite essays are only a click away, the list of diversions will leave you howling (be sure not to miss Dennis Dutton's Smoke-Free Carmen.) And if you really have time to spare, scroll all the way down to the bottom and check out the list of classics. Thought provoking essays from years past are a window into the prevailing zeitgeist.
