    Explains the distinction between applied, normative, and meta-ethics with examples.

    Applied ethics addresses specific moral issues like euthanasia or factory farming.

    Meta-ethics analyzes the nature and meaning of moral claims.

The basic divisions of philosophy, specifically the distinction between Metaethics (the nature of moral judgments) and Normative Ethics (how one ought to act).
The core debate between Moral Realism (the position that objective moral facts exist) and Moral Anti-Realism (the rejection of objective moral facts).
The semantic distinction between Cognitivism (the view that moral statements express propositions that can be true or false) and Non-Cognitivism.
J.L. Mackie's classic formulation of Moral Error Theory, particularly his 'Argument from Queerness' and 'Argument from Relativity'.
The practical aftermath of accepting error theory: comparing Moral Abolitionism (getting rid of moral discourse) with Moral Fictionalism (retaining moral discourse as a useful fiction).
Jonas Olson's specific defense of error theory, including his critique of 'companions in guilt' arguments that attempt to link moral facts to epistemic facts.
Evolutionary Debunking Arguments (EDAs) in metaethics, which explore how evolutionary theory might undermine the objective truth of moral beliefs.
The societal and legal implications of moral nihilism, exploring how communities can construct functional legal and social systems without relying on objective moral truths.

Metaethics is the branch of philosophy that examines the nature of moral properties, statements, and knowledge, distinguishing it from normative ethics (which develops moral theories) and applied ethics (which applies moral principles to specific cases). Key metaethical approaches include moral realism (which holds that moral properties exist), error theory (which argues that moral statements are uniformly false because no moral properties exist), and non-cognitivism (which claims moral judgments express attitudes rather than beliefs). The debate centers on whether moral properties are objective and prescriptive, and whether we can have moral knowledge. Error theorists, following John Mackie's influential work, argue that moral properties would need to be 'queer' or non-natural to be both objective and prescriptive, which they find implausible. This leads to questions about how we should respond to moral error theory, with alternatives including fictionalism, conservationism, and abolitionism.
