This list of ethics topics puts articles relevant to well-known ethical (right and wrong, good and bad) debates and decisions in one place - including practical problems long known in philosophy, and the more abstract subjects in law, politics, and some professions and sciences. It lists also those core concepts essential to understanding ethics as applied in various religions, some movements derived from religions, and religions discussed as if they were a theory of ethics making no special claim to divine status.
The list also includes articles on non-ethics topics or fictional works or part of works that include a substantial ethical debate; These are fairly obviously distinguished from ethical concepts by name alone. Inclusion or exclusion of an article is obviously an ethical issue in itself, as different people regard different issues as 'substantial', and different ethical works as influential.
