Writers we think are all wrong and want to read anyway come in two kinds: those who are good writers and bad thinkers — Christopher Hitchens, Norman Podhoretz, and Gore Vidal, each in his terribly different way, are instances of that — and those who may not be original stylists but who we admire for trying to be better thinkers than they were before, stumbling toward truth from a starting place very different from the one we happened to inherit. I disagree, for instance, with David Frum about almost everything, from Iraq to the legacy of Pierre Trudeau in our native Canada, but never doubt his integrity or desire to tell the truth about the world.

Even though I’m not a utilitarian, and so I tend to disagree with Singer in terms of the general framework, this book literally changed my life. I read it many years ago, in the 1990s, when I was in Knoxville, Tennessee.

I often hate-read the Daily Mail. It’s the worst of media and the worst of mankind distilled into one publication and in some ways it feels a moral duty to be familiar with it. Too often we all bolt ourselves into an echo chamber, which I think lacks courage, and can lead to a kind of intellectual conceitedness.

I read the New Yorker film critic Anthony Lane. Don’t always agree with his opinions on movies but he’s always deadly funny.
