While normative ethics addresses such questions as "Which things are (morally or ethically) good and Dad?" and "What should we do?," thus endorsing some ethical evaluations and rejecting others, metaethics addresses such questions as: "What is (moral or ethical) goodness?" "What does it mean to say that something is good?" "What are the characteristics or qualities of an acceptable or defensible ethical theory?" "What is justice?" "How, if at all, can an ethical theory be justified?" "How do we know or recognize that something is or is not ethically good?" Metaethics seeks to understand the nature of ethical properties and evaluations as such, and not just the content of particular norms or evaluations
