The Semantic Alchemy of Quasi-Realism: A Shift in Interpretation Systems
The Frege-Geach problem serves as the most formidable challenge for any non-cognitivist account, demanding that moral meaning exist within logical structures. As a metaphysician, I contend that the struggle to locate moral meaning within conditionals, negations, and disjunctions serves as the crucible for anti-realist moral inquiry. To evaluate Simon Blackburn’s Quasi-Realism, one must view it not merely as a technical maneuver, but as a symptom of a broader historical shift in "interpretation systems"—the complex networks of frameworks, norms, and values that shape our understanding of reality. This essay argues that while Blackburn successfully resolves the Frege-Geach problem, he does so by adopting a minimalist, deflationary account of truth that renders his framework nearly indistinguishable from Moral Realism. I propose that the metaethical project remains trapped within the Foundationalist/Representationalist paradigm and that the path forward necessitates the construction of a radical, interpretivist framework that accepts moral discourse as a self-contained, humanly generated system of normativity.
I. The Evolution of Metaethics: A Framework of Systems
The history of metaethics reflects a gradual shift in interpretation systems. One analyzes this evolution through three distinct stages:
Foundationalist Interpretation System: Early metaethicists, including A.J. Ayer, attempted to establish this system. They sought to secure moral knowledge through reason and establish a clear distinction between moral facts and non-moral facts. In this stage, the subject functions as the guarantor of truth, and the goal remains the establishment of a secure foundation through rational inquiry.
Representationalist Interpretation System: This stage emerges through the recognition that knowledge involves mediation by the mind, with our understanding of reality shaped by cognitive frameworks. Here, the subject constructs reality, and the goal involves representing the world through language. Blackburn’s work occupies this space, attempting to reconcile moral attitude with the cognitive requirements of language.
Interpretivist Interpretation System: This stage acknowledges that our understanding of reality is "always already" interpreted, with no direct access to objective truth. The subject acts as the locus of interpretation, and the goal shifts from adjudicating certainty to clarifying the frameworks and norms that shape our understanding.
The evolution from Ayer to Blackburn highlights a shift in philosophical intent, prioritizing semantic precision over phenomenological adequacy. While early theorists like Ayer attempted to dismiss moral judgments as cognitively meaningless, the subsequent shift toward Representationalism forced a confrontation with the "Embedding Problem".
II. The Frege-Geach Problem and the Crisis of Indistinguishability
Blackburn addresses the embedding problem by constructing a system of "higher-order attitudes," where an agent expresses disapproval not only of a specific act but also of the failure to disapprove within inferential contexts. This strategy mimics cognitivist embedding behavior, which some defenders view as a feature rather than a bug; by replicating the logic of moral discourse, the Quasi-Realist demonstrates that anti-realism requires no ontological sacrifice.
I reject this defense. Blackburn adopts a deflationary account of truth, treating it as a formal device rather than a relational, correspondence-based property. This indistinguishability erodes the distinction between "expressing an attitude" and "stating a fact," making the anti-realist commitment functionally vacuous. If both the Realist and the Quasi-Realist utilize identical logical structures and identical minimalist conceptions of truth, the anti-realist commitment becomes empty. Moral language remains constitutive of our ontology; thus, treating moral discourse as "quasi-real" effectively forces the anti-realist to play by the Realist's rules, ultimately losing the distinct identity of their own position.
One might raise a counterargument: if the logic of moral discourse works exactly like the logic of factual discourse, does that not imply that moral discourse must be representational? I argue that this confuses functionality with ontology. A map of a city functions by representing streets, but a moral code functions by orienting human behavior. To force the moral code into the "representationalist" system (Stage 2) requires the very "semantic alchemy" that leads to Blackburn’s collapse into Realism.
III. Toward a Radical Interpretivist Framework
The metaethical project remains trapped within the Foundationalist/Representationalist paradigm. The drive toward "system-closure" has resulted in increasingly complex frameworks that replicate the structure of moral facts without positing the existence of those facts. This evolution has improved semantic precision but obscured the initial insight: morality functions as a matter of human attitude rather than objective fact.
A more robust path forward necessitates the construction of a radical, interpretivist framework that accepts moral discourse as a self-contained, humanly generated system of normativity. We must cease the attempt to make moral discourse "truth-apt" through deflationary mimicry. Instead, we should embrace the interpretivist position, which acknowledges that our understanding of reality is "always already" interpreted. Philosophy must pivot from acting as an epistemological tribunal to serving as the discipline that clarifies the frameworks of interpretation we inhabit. By abandoning the search for "objective" truth-aptitude, we can finally begin to understand moral discourse as it functions in human life—as a vital system of normative meaning rather than a flawed attempt at empirical description.

This book develops a structural critique of contemporary metaethics by arguing that the dominant debate between moral realism and expressivism has reached a point of theoretical indistinguishability under conditions of semantic minimalism. Focusing on Simon Blackburn’s quasi-realism, Allan Gibbard’s norm-expressivism, and Robert Brandom’s inferentialism, the project argues that attempts to preserve non-cognitivist intuitions while satisfying Frege-Geach-style compositional constraints result in a form of “semantic alchemy”: the transformation of expressive states into truth-apt structures without ontological commitment.
The central claim is that quasi-realism succeeds only by importing the full inferential architecture of cognitivism—truth predicates, logical embedding, and compositional semantics—while maintaining an anti-realist metaphysical posture that no longer does substantive theoretical work. As a result, the realism/anti-realism distinction collapses at the level of functional semantics, leaving only competing interpretations of the same inferential structure.
Engaging deeply with Brandom’s inferentialism, Gibbard’s planning-state semantics, and contemporary meta-semantics (including deflationary theories of truth and use-theoretic meaning), the book argues that the Frege-Geach problem is not merely a technical challenge for expressivism, but a symptom of a deeper constraint: any system capable of supporting normative inferential stability will inevitably reconstruct realist structure regardless of its metaphysical commitments.
To resolve this impasse, the book proposes a shift toward a radical interpretivist framework, in which moral discourse is understood not as truth-apt representation nor as reducible expression, but as a self-contained system of norm-governed interpretation. On this view, moral language is neither descriptive nor illusory; it is constitutive of a socially embedded inferential practice that cannot be evaluated from a standpoint external to interpretation itself.
This reframing dissolves the traditional metaethical taxonomy—realism, expressivism, quasi-realism—and replaces it with a model of competing interpretation systems, each defined by its inferential commitments rather than its metaphysical claims.
Introduction: The Semantic Pressure of Quasi-Realism and the Problem of Metaethical Distinction
The central ambition of contemporary metaethics has been, for several decades, to preserve the intelligibility of moral discourse without committing oneself to a robustly realist ontology of moral facts. This ambition has generated a remarkable range of positions—non-cognitivism, expressivism, quasi-realism, and planning-state semantics—that attempt, in different ways, to reconcile two pressures that initially appear to pull in opposite directions. On the one hand, moral language behaves with a striking degree of logical discipline: it embeds in conditionals, supports valid inference, and appears to obey compositional constraints indistinguishable from ordinary descriptive discourse. On the other hand, the metaphysical postulation of irreducible moral facts has come to seem, to many philosophers, epistemically extravagant or explanatorily unnecessary.
The Frege-Geach problem crystallizes this tension with unusual clarity. If moral utterances are merely expressions of non-cognitive attitudes—approval, disapproval, endorsement, or rejection—then it becomes difficult to explain why such utterances preserve their inferential role when embedded in complex logical contexts. The difficulty is not merely technical. It exposes a deeper constraint on any adequate theory of meaning: whatever moral language is, it must be capable of sustaining the inferential architecture that gives reasoning its structure. Any theory that fails this test appears to misdescribe not only moral discourse, but the very logic of our practical reasoning.
It is in response to this constraint that Simon Blackburn’s quasi-realism acquires its distinctive philosophical significance. Rather than abandoning expressivism in the face of embedding pressures, Blackburn proposes to reconstruct the full inferential surface of realist moral discourse from within an expressivist foundation. Moral claims, on this view, are ultimately expressive of attitudes; however, by deploying higher-order attitudes and adopting a disciplined commitment to the norms of assertion, the quasi-realist earns the right to speak as if moral claims were truth-apt. The result is a position that preserves expressivism at the level of metaphysical commitment while recovering, at the level of linguistic practice, the structure of cognitivist discourse.
At first glance, this strategy appears to represent a decisive advance over earlier non-cognitivist theories. It avoids the crude reduction of moral language to emotional expression, and it respects the compositional and inferential demands highlighted by Frege and Geach. Moreover, by embracing a deflationary account of truth, quasi-realism appears to dissolve the need for any robust correspondence relation between moral statements and moral facts. Truth, on this view, becomes a logical or expressive device rather than a metaphysically loaded relation. In this respect, quasi-realism presents itself as a theoretically economical position: it preserves everything we need from moral discourse while discarding the ontological commitments we no longer wish to endorse.
The central thesis of this book is that this appearance is misleading. I argue that quasi-realism achieves its success only by importing, in disguised form, precisely the inferential and semantic commitments that originally distinguished cognitivist realism from expressivist alternatives. Once these commitments are fully articulated—particularly in light of contemporary developments in inferentialism (Brandom), norm-expressivism (Gibbard), and deflationary theories of truth (Horwich)—the distinction between quasi-realism and a suitably minimalist form of realism becomes increasingly difficult to sustain. The result is not a stable reconciliation of opposing views, but a progressive erosion of the conceptual boundary that was meant to separate them.
To clarify this claim, I introduce the notion of semantic alchemy. By this term, I refer to the systematic transformation of non-cognitive expressive states into structures that are functionally indistinguishable from truth-apt propositions within inferential practice. Semantic alchemy occurs when a theory preserves its anti-realist metaphysics only by reconstructing, at the level of logical behavior, all of the features that characterize realist semantics: compositionality, embedding stability, inferential closure, and truth-like endorsement conditions. The quasi-realist, on this account, does not eliminate realism so much as reproduce its functional profile under a different description.
This diagnosis places quasi-realism in a more general methodological context. Contemporary metaethics, I suggest, remains largely organized around what might be called a representationalist constraint: the assumption that semantic adequacy requires a mapping between linguistic expressions and either (i) external facts, or (ii) internal states that can substitute for such facts while preserving inferential structure. Even expressivist and deflationary approaches, which explicitly reject robust correspondence theories of truth, often retain this representationalist ambition in attenuated form. The result is a persistent tendency to reconstruct moral discourse as though it must either represent moral reality or simulate the functional equivalent of such representation.
Against this backdrop, the interpretivist alternative developed in this book aims to displace the representationalist constraint altogether. Rather than treating moral discourse as either descriptive or pseudo-descriptive, I propose that it be understood as a self-contained system of norm-governed interpretation. On this view, moral language is not primarily a vehicle for representing states of the world, nor is it merely a projection of non-cognitive attitudes onto a neutral descriptive base. It is, instead, a practice governed by inferential and evaluative norms internal to a historically and socially embedded framework of human interpretation.
This shift has two immediate consequences. First, it reframes the Frege-Geach problem not as a puzzle about how non-cognitive attitudes can mimic propositional structure, but as evidence that inferential stability itself generates structural constraints that any adequate normative system must satisfy. Second, it dissolves the pressure to locate moral discourse on either side of the realism/anti-realism divide. If meaning is fundamentally a function of inferential role within interpretive systems, then the question is not whether moral statements correspond to independent moral facts, but how they operate within the normative architecture of a given practice.
It is important to emphasize that this interpretivist proposal is not intended as a form of quiet relativism. Interpretive systems are not unconstrained. They are subject to internal pressures of coherence, inferential stability, and social uptake, as well as external constraints arising from interaction with other normative and descriptive systems. The claim is not that “anything goes,” but rather that the criteria of adequacy for moral discourse are internal to the interpretive frameworks within which such discourse functions.
The structure of the book reflects the gradual unfolding of this argument. The first part reconstructs the historical emergence of the interpretive pressures that shape contemporary metaethics, beginning with early non-cognitivism and culminating in representationalist and inferentialist responses. The second part examines quasi-realism and planning-state expressivism in detail, focusing on their strategies for resolving the Frege-Geach problem and the implicit commitments these strategies introduce. The third part develops the semantic alchemy thesis and argues that quasi-realism collapses into a functionally realist position under conditions of deflationary truth. The final part articulates the interpretivist alternative and situates it as a post-metaethical framework capable of preserving the explanatory insights of expressivism without inheriting its representational constraints.
The goal of this inquiry is not to dismiss the achievements of quasi-realism or related theories. On the contrary, it is precisely their success that motivates the present investigation. A theory that can reconstruct the inferential behavior of moral discourse so effectively invites a deeper question: what, if anything, remains of the distinction between realism and its supposed alternatives once the functional structure of moral language has been fully preserved? If the answer is “less than previously assumed,” then the task of metaethics may not be to refine the realism/anti-realism opposition, but to reconsider whether that opposition continues to organize our theoretical options in a coherent way.
In this sense, the argument of this book is ultimately diagnostic rather than eliminative. It seeks to show not that moral discourse is illusory, nor that metaethical theories are misguided, but that the conceptual architecture within which they are formulated may itself be undergoing a subtle but decisive transformation. Quasi-realism, on this reading, is not a final position in metaethics but a transitional one: a moment in which expressivist commitments are gradually re-described in realist terms under the pressure of semantic and inferential demands.
The task that follows from this diagnosis is to take seriously the possibility that moral discourse is neither a window onto a domain of independent facts nor a mere projection of subjective attitudes, but a structured and autonomous system of interpretation whose philosophical analysis requires categories that do not reduce to either pole of the traditional debate. It is toward this task that the remainder of the book is directed.
This book argues something stronger than standard quasi-realist critique:
The success of quasi-realism is not a vindication of expressivism, but evidence that expressivism cannot be coherently distinguished from realism once inferential adequacy is achieved.
It introduces:
- A theory of interpretation systems replacing metaethical categories
- A diagnosis of semantic mimicry (semantic alchemy) in quasi-realist theories
- A reinterpretation of Frege-Geach as a structural constraint on meaning systems
- A positive interpretivist alternative that avoids both realism and expressivist reductionism
Critical Review of Semantic Alchemy: Interpretation Systems and the Collapse of Metaethical Distinctions
There is a particular kind of philosophical book that is most dangerous not when it is obviously wrong, but when it is almost right. Semantic Alchemy is such a book. It is ambitious, systematic, technically informed, and written with a level of conceptual confidence that will undoubtedly attract readers dissatisfied with the increasingly repetitive realism-versus-expressivism debates of contemporary metaethics. Yet its central thesis—that quasi-realism collapses into realism under the pressure of compositional semantics—rests on a subtle but decisive equivocation between semantic function and ontological commitment.
The book's fundamental achievement is diagnostic. Its treatment of the Frege-Geach problem is among its strongest contributions. Rather than presenting Frege-Geach as a localized embarrassment for expressivism, the author reframes it as a universal constraint on semantic adequacy. This is an insightful move. By emphasizing compositionality, embedding, and inferential stability, the author correctly identifies the structural pressures that have driven modern expressivists toward increasingly sophisticated semantic architectures.
The discussions of Blackburn and Gibbard are particularly effective. The author convincingly demonstrates that both quasi-realism and planning-state semantics reconstruct much of the machinery traditionally associated with propositional thought. The book is at its best when it exposes how anti-realist theories must repeatedly rebuild inferential structures they originally sought to avoid.
However, the argument becomes considerably more controversial once it moves from diagnosis to metaphysical conclusion.
The central claim is that if expressivism successfully reproduces the inferential behavior of realist discourse, then the distinction between realism and expressivism becomes semantically vacuous. This conclusion appears plausible only because the book quietly assumes a verificationist criterion of theoretical identity: theories that generate identical inferential outputs are treated as identical for all philosophically significant purposes.
A realist should reject this assumption immediately.
Two theories can possess identical observable or inferential consequences while differing profoundly in what they claim exists. The history of science provides numerous examples. Competing interpretations of quantum mechanics often generate identical empirical predictions while remaining ontologically distinct. Likewise, one can accept that quasi-realists and realists employ similar inferential structures while denying that this exhausts the meaning of their disagreement.
The author repeatedly invokes a Quinean criterion of ontological commitment, but Quine himself never claimed that ontology could be reduced entirely to inferential behavior. Ontological commitment concerns what a theory quantifies over, not merely how it functions inferentially. The book's transition from "semantic indistinguishability" to "theoretical identity" therefore proceeds too quickly.
Indeed, the entire collapse thesis depends upon treating semantics as the final court of appeal. But why should we accept this?
A moral realist can grant every semantic point made in the book while maintaining that moral judgments are true because they correspond to mind-independent normative facts. The quasi-realist can grant the same semantic structure while denying those facts. The disagreement remains substantive precisely because it concerns ontology rather than compositional semantics.
The author seems aware of this objection, which explains the later move toward "interpretivism." Here the book abandons traditional metaethysics altogether and reconceives morality as a self-contained system of inferential practices. At first glance, this appears refreshingly original. Yet one quickly notices that interpretivism inherits many of the difficulties traditionally faced by pragmatism and anti-realism.
Most importantly, interpretivism struggles to explain moral criticism across systems.
Consider the book's discussion of pluralism. The author argues that normative systems can be evaluated according to coherence, inferential stability, and social reproducibility. But these criteria are procedural rather than moral. A coherent and stable system could still be morally abhorrent. Fascism, religious extremism, and caste systems may possess substantial internal coherence. If coherence is the standard, why are such systems wrong?
The book's answer is revealing. It suggests that such systems fail within liberal-democratic interpretive frameworks. But this simply relocates the problem. Why privilege liberal-democratic frameworks? The answer cannot be inferential stability alone, because many oppressive systems exhibit remarkable stability. At this point the interpretivist appears forced to smuggle in substantive moral values that the framework officially disavows.
Ironically, this is precisely the criticism the author levels against constructivists such as Rawls and Scanlon.
The book therefore falls victim to its own methodological suspicion. Just as it accuses quasi-realists of quietly importing realist structures, interpretivism quietly imports liberal normative commitments while claiming merely to describe inferential systems. The result is not the elimination of moral ontology but its concealment.
The treatment of Brandom is also open to challenge. The author presents inferentialism as a hidden force driving expressivism toward realism. Yet Brandom himself is not a realist in any straightforward sense. Inferential role semantics was developed precisely to loosen the traditional connection between meaning and correspondence. The author sometimes writes as though propositional structure automatically entails realism, but this inference is far from obvious. One can accept propositions, truth-aptness, and compositionality while remaining anti-realist about the metaphysical status of normative facts.
Perhaps the deepest issue concerns the book's conception of philosophy itself.
The final chapters propose that philosophy should cease adjudicating truth and instead map interpretation systems. This proposal is intellectually fashionable, but it risks surrendering philosophy's most important ambition. Human beings do not merely want descriptions of competing frameworks; they want to know which frameworks are justified. They want reasons for preferring justice to domination, truthfulness to deception, and human dignity to cruelty.
System mapping can illuminate these disputes, but it cannot resolve them.
Consequently, the interpretivist conclusion may be less radical than the author believes. Rather than transcending realism and anti-realism, it may simply constitute another anti-realist position—one that replaces moral facts with inferential practices while retaining many of the same explanatory burdens.
Despite these criticisms, Semantic Alchemy is a significant and thought-provoking work. Its strongest contribution is not the collapse thesis itself but the challenge it poses to complacent expressivism. Any quasi-realist who reads this book will emerge with a deeper appreciation of how much semantic machinery their position requires. Likewise, realists will find themselves forced to clarify why semantic equivalence does not eliminate ontological disagreement.
Whether the author's interpretivist alternative succeeds is doubtful. Yet the book succeeds in something perhaps more important: it reveals that many contemporary metaethical disputes may be less about moral language than about competing conceptions of what philosophy itself is supposed to accomplish.
For that reason alone, it deserves serious attention. Not because it has solved the problems of metaethics, but because it has exposed how many of those problems remain unresolved beneath the surface of contemporary debate.
