Ethics (also known as moral philosophy) is a branch of philosophy which seeks to address questions about morality; that is, about concepts such as good and bad, the noble and the ignoble, right and wrong, justice, and virtue.
Major branches of ethics include:
* meta-ethics, about the theoretical meaning and reference of moral propositions and how their truth-values (if any) may be determined; * normative ethics, about the practical means of determining a moral course of action; * applied ethics, about how moral outcomes can be achieved in specific situations; * moral psychology, about how moral capacity or moral agency develops and what its nature is; and * descriptive ethics, about what moral values people actually abide by.
