There is broad consensus that there are a handful of types of ethical analysis, though not perhaps on the precise nature of these. The degree of consensus is limited by the tendency of philosophers to argue for the
superiority of one type. The types listed here are grounded in the types of human decision-making discussed in GA. They might thus have been designated using linked notation. Rights are a type of rule.
