Theories which claim that morality is derived from reasoning about implied imperatives ( universal prescriptivism ), the edicts of a god ( divine command theory ), or the hypothetical decrees of a perfectly rational being ( ideal observer theory ), are considered anti-realist in the robust sense used here, but are considered realist in the sense synonymous with moral universalism.
