How Would Expressivism Change Value Uncertainty?
1. Separate two questions first
At least two questions should be distinguished when evaluating expressivism.
- Semantic, psychological, and practical question: when humans say “X is wrong” or “Y ought to be done,” what psychological states, attitudes, plans, or normative commitments are expressed?
- Ontological question: do objective reasons, values, or normativity exist independently of present human moral practice?
Even very strong success for expressivism on the first question would not automatically settle the second in favor of anti-realism. This page puts that separation at the center.
2. The attraction of expressivism remains
Expressivism captures the strongly practical character of moral language. “X is wrong” is deeply connected not merely with describing the world, but with opposing X, planning to avoid X, or adopting a normative stance that does not permit X. Sophisticated non-cognitivist theories after Blackburn and Gibbard have tried to preserve this practical role while explaining how moral discourse can still support talk of truth, facts, logical inference, and disagreement.
This page therefore does not deny that moral language has expressive functions. It treats expressivism as one important explanatory hypothesis about existing human morality.
3. “Expression” is not transparent readout of inner attitudes
It is too strong to interpret expressivism as saying that every moral utterance must faithfully reveal the speaker's actual inner attitude. People can lie, speak under social pressure, misidentify their own attitudes, or use a conventional expression insincerely. A linguistic form can be conventionally connected with a type of attitude or commitment without each token utterance transparently leaking the speaker's true psychology.
Therefore, the mere possibility of deception, performance, self-deception, or unintended expression is not a direct counterexample to sophisticated expressivism.
The stronger question is whether a fully sincere and competent subject could genuinely judge that “X is wrong” while lacking the non-cognitive attitude that a given expressivist theory treats as essential to that judgment. This connects to debates about moral judgment and motivation and to hybrid or ecumenical expressivism.
4. The “X is really wrong” use is already a known problem
Ordinary moral discourse often behaves more strongly than a report such as “I dislike X.” It is natural to say that “even if I and my whole society had approved X, X would still have been wrong,” or that another person is not merely differently disposed but mistaken.
Yet this does not straightforwardly refute expressivism. Quasi-realism is precisely the project of asking how far talk of truth, objectivity, error, and apparent mind-independence can be legitimately recovered from a non-cognitivist foundation.
The relevant question is therefore not simply whether moral discourse sounds objective, but whether the practice-internal objectivity recovered by quasi-realism is identical to normativity independent of subjects, communities, and practices.
5. Do not treat folk morality as uniformly realist
It would also be too strong to say that ordinary people uniformly understand morality as universal objective fact. Experimental work on folk metaethics finds substantial objectivist responses in some cases, but also more relativist responses depending on the issue, cultural distance, and how disagreement is framed.
A more defensible claim is: human moral practice clearly contains uses that demand correctness beyond mere personal attitude and sometimes beyond the speaker's community or era. But that commitment is not necessarily uniform across all people and all moral domains.
6. Human moral semantics does not directly determine value ontology
This is the most important point for the Core. Suppose that humanity's vocabulary of “good,” “bad,” and “ought” historically developed largely for coordination, blame, planning, and attitude regulation, and suppose its present semantics is best explained in expressivist terms.
It still would not immediately follow that no normative facts exist independently of human practice. There is no guarantee that the activities humans presently classify as “morality” completely track every kind of normativity that might exist.
In an extreme possibility, present human moral discourse could function almost entirely as a social mechanism for coordinating attitudes while there nevertheless exist practice-independent reasons or values that humanity has not yet recognized.
This is not an argument for realism. It is an anti-closure claim: semantic success for expressivism alone cannot reduce the probability of unknown objective normativity to zero.
7. Ethics might exist outside what we currently treat as ethical life
Even if objective normativity exists, there is no guarantee that it maps closely onto human guilt, fairness intuitions, coordination habits, present concepts of suffering, or existing moral vocabulary. Future cognitive subjects might discover normative structure in physical, phenomenal, or relational features that we do not presently classify as ethical questions.
Accordingly, fully explaining current moral discourse would not be the same achievement as fully explaining the ontology of normativity itself. This does not claim that unknown ethics must exist. It is a methodological refusal to treat the boundaries of present moral practice as the boundaries of the space of possible value.
8. The tension with the Core weakens but does not disappear
An earlier version treated strong expressivism as shifting value inquiry relatively directly from discovery of external truth toward construction and reconstruction. That was too strong.
More precisely, if expressivism is correct about present human moral language, a large part of the study of existing morality may indeed be understood as the construction and revision of attitudes, plans, institutions, and reflective endorsements. But it does not follow that value inquiry as a whole reduces to construction. Inquiry into practice-independent normativity remains a separate possibility as long as such normativity has not been ruled out.
The Core can therefore remain independent of the assumption that existing moral language already describes objective moral facts while still preserving inquiry into unknown reasons, values, or normative structure.
9. Expressivism alone does not defeat the stopping condition
An earlier version suggested that, if strong expressivism were correct, the stopping condition in which normatively binding objective value appears at the foundational layer might itself fail to exist.
This should be revised. Expressivism about human moral language alone does not rule out foundational normativity. To rule it out would require the additional ontological thesis that no normativity exists independently of human attitudes, practices, or constructions.
Conversely, if a future cognitive subject were to discover, independently of present moral vocabulary, normativity that itself supplied reasons either at the foundational layer or as an overwhelmingly strong best explanation, that discovery could still substantially update the Core.
10. Provisional position
- Treat expressivism as an important explanatory hypothesis about human moral discourse.
- Do not treat expression as a transparent readout of the speaker's current psychology.
- Recognize that the realist-seeming character of moral discourse is already a central target of quasi-realism.
- Do not assume folk morality is uniformly objectivist.
- Separate semantic expressivism from global ontological anti-realism.
- Do not infer the nonexistence of unknown practice-independent normativity from the constructed character of present human morality.
Just as this project refuses to fix present morality as the universe's final value, it should also refuse to fix the semantics of present moral language as the universe's final value ontology.
