Tyler Cowen is an economist, aptly self-described "curious intellectual nerd polymath," and a gifted blogger. His new book is the only one I've ever pre-purchased through Amazon. This in itself is a tribute to Cowen's capacity to mobilize appropriate incentives: He secreted a second blog, and advertised on Marginal Revolution that access was available only to those who wrote to say they'd pre-purchased a copy of DYIC. I spent this afternoon reading the book, and my overall impression is that "Sometimes, a bunch of appetizers does not make a meal." Because Cowen's brain brims with creative ways to approach life from an idiosyncratic angle, his blog has marvelous little jags, lists, apercus gleaned from his vast reading. This book is not quite a blook, but it would have greatly benefited from a co-author whose strength was more inclined to thoroughness. While he admits that his habit is to "stop writing just a bit before I have said everything I want to. I find it better to approach the next writing day 'hungry'..." (123), I was left hungry for more detail or resolution on almost every topic. As a troubling example, he introduces the concept of the "Me factor", and deploys it in several instances, but the only explanation provided was this very skimpy account, that focusing "our attention on ourselves ... is in fact our favorite topic. Me, me, me. ... [T]he 'Me factor', as I will call it." (52-3) There are tons of ideas broached here, and the chapters on Art and Food are particularly stimulating. The defense of self-deception felt self-indulgently sketchy, and the final account of how to deal with torture piffles into "Quite simply, it is hard to show other people, in a convincing manner, that we are telling the truth. In the meantime, file this problem under 'Difficult to Solve' and stay out of the wrong cities." (104). If truth in subtitles were enforced, it should be noted that Cowen offers very little to help survive your next meeting, nor do his thoughts on motivating your dentist inspire much confidence.
