There is a family of metaethical views according to which (i) there are no objectively correct moral standards and (ii) whether a given moral claim is true depends in some way on moral standards accepted by either an individual (forms of subjectivism) or a community (forms of relativism). This chapter outlines the three most important versions of this type of theories: old-fashioned subjectivism and relativism, contextualism and new wave subjectivism and relativism. It also explores the main advantages of these views and the key objections to them.
