The Sun/Daily Mail/other various rags. It’s not that I go out of my way to read them, but back in England any fish and chip shop worth their salt delivers your food wrapped in newspaper. Tabloids are cheapest. You can’t help but catch the headlines.

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.

This book is a great place for people to begin who want to learn more about strategy. Gray does what he says he is going to do: he talks about modern strategy. He talks about everything from the principles of nuclear strategy to the basic fundamentals of strategy itself, the importance of Clausewitz, and of strategic context. I don’t agree with everything he says, but no strategist agrees with everything another one has to say. But his book is a great place to begin.

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.
