 Morality requires too much. The basic worry is that the morality system is voracious and is creeping into all aspects of our lives, to the detriment of other important values. The worry expressed by 4 takes a variety of forms. For example, some take issue with a presupposition of 4, arguing that there are no moral principles at all if we think of these principles as guiding action. Some argue that there are no moral principles that are complete, because morality is not something that is codifiable. And, even if morality was codifiable, the ‘principles’ would be extremely specific, and not qualify as principles at all.
