Meta-ethics is the branch of ethics that seeks to understand the nature of ethical properties, statements, attitudes, and judgments. Meta-ethics is one of the four branches of ethics generally recognized by philosophers, the others being descriptive ethics, normative ethics and applied ethics.
Divine command theory is a meta-ethical theory which proposes that an action's status as morally good is equivalent to whether it is commanded by God. The theory asserts that what is moral is determined by what God commands, and that to be moral is to follow his commands. Followers of both monotheistic and polytheistic religions in ancient and modern times have often accepted the importance of God's commands in establishing morality. Numerous variants of the theory have been presented: historically, figures including Saint Augustine, Duns Scotus, and Thomas Aquinas have presented various versions of divine command theory; more recently, Robert Merrihew Adams has proposed a "modified divine command theory" based on the omnibenevolence of God in which morality is linked to human conceptions of right and wrong. Paul Copan has argued in favour of the theory from a Christian viewpoint, and Linda Zagzebski's divine motivation theory proposes that God's motivations, rather than commands, are the source of morality
Pragmatic ethics is a theory of normative philosophical ethics. Ethical pragmatists, such as John Dewey, believe that some societies have progressed morally in much the way they have attained progress in science. Scientists can pursue inquiry into thetruth
