Deep down we all realize that something is wrong with the world. We differ greatly, however, when it comes to diagnosing its ills. For some, the problems are essentially matters of coordination and distribution of material goods. For others, they are more structural than individual. People make bad decisions, and providing fewer choices or better structures for decision-making would lead to progress. For many others, while such issues have to be recognized as legitimate, they do not yet get at the core of the problems, which penetrate below the surface into moral virtue and spiritual character.
