Moral Cognitivism
Moral judgments express beliefs and are truth-apt. Internal diversity concerns realism, anti-realism, and constructivism.
Interactive Metaethics
Moral Cognitivism vs. Non-Cognitivism
Track how major metaethical theories connect and where they are vulnerable: truth-aptness, ontology, semantics, motivation, and disagreement.
Core Taxonomy
Moral Non-Cognitivism
Moral judgments primarily express practical attitudes, plans, or prescriptions rather than ordinary belief-states.
Bridge and Hybrid Strategies
Views like quasi-realism or sophisticated expressivism try to recover truth-talk and logical structure without robust moral realism.
Undergirding Issues
- Truthmaker Maximalism: does every truth require robust ontological grounding?
- Queerness challenge: are objective moral properties too metaphysically and epistemically strange?
- Frege-Geach problem: can expressivism preserve valid inference in embedded contexts?
- Motivation internalism: does sincere moral judgment necessarily motivate?
- Moral disagreement: is clash primarily doxastic, attitudinal, or mixed?
- Naturalism vs. non-naturalism: what kind of properties could moral truths be about?
- Evolutionary debunking arguments: do genealogical explanations undercut moral justification?
- Supervenience and explanation: can moral differences occur without non-moral differences?

Niche and Hybrid Extensions
Non-Realist Cognitivism
Keeps truth-aptness while denying stance-independent moral facts; map branches include error theory, fictionalism, and relativist cognitivist options.
Moral Fictionalism
Treats moral discourse as a useful practical fiction: we continue using moral language without full realist ontological commitment.
Cognitivist Moral Relativism
Holds that moral claims are truth-apt but truth may be relative to frameworks, standards, or contexts rather than universally stance-independent facts.
