John Searle criticized aspects of Hilary Putnam’s philosophy of mind and language, particularly Putnam’s functionalism and later his turn to internal realism and anti-metaphysical views. Below is a detailed citation and evaluation of Searle’s criticism.
1. Criticism of Functionalism
Putnam is well-known for introducing functionalism in the philosophy of mind, which holds that mental states are defined by their functional roles—what they do—rather than by what they are made of.
Citation:
Searle’s main critique appears in:
Searle, John. The Rediscovery of the Mind. MIT Press, 1992.
Searle attacks functionalism throughout this book, with specific references to Putnam’s version.
Searle’s Argument:
- Functionalism treats the mind as a computer program, focusing only on syntax (formal structure), ignoring semantics (meaning).
- He argues that this misses consciousness and subjective experience, i.e., qualia.
- The Chinese Room Argument (Searle, 1980) is a central part of this critique: A machine could pass a Turing test (appear intelligent) by manipulating symbols without actually understanding—thus, computation is not sufficient for mind.
Evaluation:
Searle’s critique is powerful in highlighting the limitations of purely functional accounts of consciousness, particularly for addressing first-person experience. However, some argue that he underplays the potential of system-level interpretations—i.e., that understanding might emerge at the level of the system, not the individual manipulator (a response to his Chinese Room Argument).
2. Criticism of Internal Realism and Anti-Metaphysics
Later in his career, Putnam embraced internal realism, arguing that truth and reality are dependent on conceptual schemes.
Citation:
Putnam articulates internal realism in:
Putnam, Hilary. Reason, Truth and History. Cambridge University Press, 1981.
Searle criticizes this view in several essays, but especially in:
Searle, John. “Hilary Putnam’s ‘Realism with a Human Face’.” The Journal of Philosophy, vol. 91, no. 9, 1994.
Searle’s Argument:
- Searle sees internal realism as a form of conceptual relativism that threatens the objectivity of truth.
- He defends direct realism: we can talk meaningfully about a mind-independent reality, even if our concepts mediate our knowledge of it.
- He argues that Putnam conflates epistemology with ontology, mistaking the conceptual nature of our knowledge for conceptual dependence of reality itself.
Evaluation:
Searle’s critique is robust in defending realism about truth and objectivity. However, some sympathize with Putnam’s project as a middle ground between metaphysical realism and relativism, seeing it as an attempt to explain how we can have objective knowledge while acknowledging the role of human cognition.
Summary of Searle’s Criticisms of Putnam
| Area | Putnam’s View | Searle’s Criticism | Evaluation |
|---|---|---|---|
| Functionalism | Mind as computational/functional system | Ignores consciousness, only deals with syntax | Strong critique; shows limits of computational theory |
| Internal Realism | Truth depends on conceptual schemes | Undermines objective reality and truth | Mixed; raises valid realism concerns, but oversimplifies Putnam’s nuance |

what other criticisms are there

Here are several notable criticisms of Hilary Putnam’s philosophy, particularly regarding his internal realism, semantic externalism, functionalism, and more. These come from a range of philosophers, both contemporaries and critics, and are grounded in peer-reviewed literature and academic commentary:
1. Internal Realism and Conceptual Relativism
- Critics argued Putnam’s internal realism slips into relativism or even solipsism. His claim that truth is relative to conceptual schemes risks undermining the objectivity of truth and leading to skepticism. Reddit+15rep.routledge.com+15eidir.org+15
- Ernest Sosa, for example, contended that internal realism smuggles in relativism under the guise of rational acceptability, making true beliefs perspective-dependent. inters.org+1OpenEdition Journals+1
- Curtis Brown went further, accusing Putnam’s internal realism of resembling subjective idealism: if existence depends on experience, the external world might disappear with the subject. Profilbaru
2. Model‑Theoretic Argument and Solipsism
- Putnam’s famous model-theoretic argument (based on the Löwenheim–Skolem theorem) was meant to challenge metaphysical realism. However, critics say it inadvertently collapses into solipsism because it treats truth as purely brain-state–dependent unless framed counterfactually. Wikipedia+15Docslib+15rep.routledge.com+15
- Putnam later admitted that his counterfactual formulation failed to avoid this problem, undermining the public intelligibility of internal realism. ResearchGate+4SpringerLink+4eidir.org+4
3. Semantic Holism and Language Learning
- Putnam’s insistence on semantic holism—that the meaning of a term depends on its relations to the entire language—faces the objection that language learning and communication would be impossible under such a view. Learning a single word would require grasping the whole system. griceclub.blogspot.com
- Scholars like Michael Dummett, Jerry Fodor, and Ernest Lepore have argued that holism undermines shared meaning and creates radical instability in what a term means over time or across speakers. Reddit+3griceclub.blogspot.com+3Wikipedia+3
4. Functionalism and the Turn Against His Early Views
- Though Putnam introduced functionalism (e.g. via multiple realizability), he later rejected it. Critics such as Jerry Fodor, Ned Block, and others criticized his early embrace, pointing out that functionalism struggles to account for phenomenal consciousness and fails to explain multiple realizability in a non-trivial way. Wikipedia+3Wikipedia+3griceclub.blogspot.com+3
- The Twin Earth thought experiment demonstrates limitations of internalist semantics and functionalist assumptions, which contributed to Putnam abandoning the view. griceclub.blogspot.com+2Wikipedia+2Wikipedia+2
5. Critiques from Philosophy of Science and Realism
- Critics like Michael Devitt and Paul Boghossian have argued Putnam’s attempt to chart a middle path between metaphysical realism and relativism yields a category mistake or an incoherent position. inters.org+3OpenEdition Journals+3Encyclopedia Britannica+3
- The retreat from internal realism to a new metaphysically realist stance (e.g., scientific realism grounded in the “no‑miracles argument”) has also been subject to scrutiny: critics ask whether Putnam’s later views really differ meaningfully from traditional realism or are just rhetorical repositionings. SpringerLink+1inters.org+1
Summary Table
| Criticism Area | Summary Critique |
|---|---|
| Internal Realism | Leads toward relativism or solipsism; truth loses objectivity. |
| Model-Theoretic Turn | Collapses into solipsism rather than undermining realism. |
| Semantic Holism | Makes language learning and shared meaning unstable. |
| Functionalism | Initially defended but later rejected; fails to address consciousness and multiple realizability properly. |
| Middle‑Path Realism | Seen as incoherent or trivial; possibly indistinguishable from standard metaphysical realism. |
Reddit Insight
While not peer-reviewed, one comment helps illustrate semantic externalism:
“Hilary Putnam famously argued that linguistic meaning content is external (to at least some degree).”ProfilbaruRedditgriceclub.blogspot.cominters.orgWikipedia+1OpenEdition Journals+1rep.routledge.com+5Reddit+5Wikipedia+5
If you’d like direct quotations, more detail on specific critics (e.g., Dummett on holism, Sosa on verificationism), or how these critiques evolved over Putnam’s career, I’d be happy to dig deeper.

Here are some well‑cited criticisms from philosophers of various aspects of Hilary Putnam’s philosophy, focusing on his internal realism, semantic holism, functionalism, and model‑theoretic argument:
1. Model‑Theoretic Argument and Challenges to Metaphysical Realism
Putnam’s model‑theoretic argument—built on Gödel’s completeness theorem and the permutation argument—claims that any “intended” model of a theory cannot be uniquely picked out, leading either to massive indeterminacy of reference or ungrounded appeals to which interpretation is “intended.” Critics argue this undermines realism, since realists can’t rule out alternative models that make the same theory true Wikipedia+15Stanford Encyclopedia of Philosophy+15We Chronicle+15.
Responses include David Lewis’s semantic magnetism (arguing some referents are metaphysically privileged) and Graham Bays’s work (“On Putnam and His Models”), which attempt to resist indeterminacy by invoking naturalness or other constraints Reddit.
2. Semantic Holism
Putnam was a staunch semantic holist: the meaning of a term depends on its relations to the entire language. Critics including Michael Dummett, Jerry Fodor, and Ernest Lepore have attacked this view for several reasons:
- It makes language learning impossible, since mastering even one word would require mastery of an entire language.
- It undermines shared meaning and communication: different individuals, with partially different vocabularies, might mean different things by the same sentence.
- Meanings become unstable: a person’s meaning for a sentence changes if their vocabulary changes BME HLT+3griceclub.blogspot.com+3Wikipedia+3Wikipedia.
Jerry Fodor, in particular, emphasized that extreme holism is incompatible with explaining content in atomistic, causal, and naturalistic terms Reddit+15Wikipedia+15griceclub.blogspot.com+15.
3. Functionalism and the Chinese Room Argument
Although Putnam originally championed functionalism (especially multiple realizability), critics point to:
- John Searle’s Chinese Room: Searle argues that syntax (functional computation) alone can never yield semantics or genuine understanding — meaning functionalism misses consciousness and intentionality BME HLT+15LiquiSearch+15Reddit+15.
- Ned Block and others similarly argued that functionalism fails to account for phenomenal consciousness and that Putnam later abandoned the view he helped pioneer Reddit.
4. Internal Realism and Relativism / Solipsism
Putnam’s internal realism holds that truth and reality depend on conceptual schemes, rejecting global metaphysical realism. Critics include:
- Curtis Brown: Internal realism collapses into subjective idealism or solipsism, since existence appears tied to conceptual or experiential frameworks—if the experiencer vanishes, so does reality BME HLT+15Wikipedia+15eidir.org+15.
- Ernest Sosa (and others): It smuggles in relativism under the guise of rational acceptability.
- Critics also point out that Putnam’s counterfactual/maximal verificationist reformulation didn’t fully escape relativism or solipsistic implications Project MUSEOpenEdition Journals.
Putnam later publicly renounced internal realism, embracing a form of common-sense or natural realism, influenced by William James and pragmatism, rejecting verificationism and conceptual relativism over reality itself Wikipedia+1eidir.org+1.
5. Theory of Meaning vs Internal Realism
Chong‑Hwan Oh (1990) argued that Putnam’s theory of meaning (e.g. Twin Earth semantics and rigidity) actually conflicts with his internal‑realist framework, making internal realism internally inconsistent unless one relinquishes the realist notion of meaning and truth PhilPapers.
Paul Abela (1996) also challenged Putnam’s attempt to link internal realism with Kant’s empirical realism, claiming the two systems fundamentally diverge regarding the ontological independence of empirical objects PhilPapers.
Summary Table
| Criticism Area | Critique Summary |
|---|---|
| Model‑Theoretic Argument | Leads to interpretative indeterminacy; hard to resist without external metaphysical assumptions |
| Semantic Holism | Undermines language learning, stability of meaning, communication across speakers |
| Functionalism | Cannot account for consciousness or understanding; criticized by Searle, Block |
| Internal Realism | Risks relativism, idealism, and solipsism; Putnam later renounced it |
| Theory of Meaning vs IR | Theories of meaning conflict with internal realism unless meaning is reconceived |
From the Philosophical Community
On semantic externalism and natural kinds (e.g., “water” vs “XYZ”), some (via Reddit commentary) argue Putnam’s account fails to respect the necessary connection between hidden structure and observable properties. This draws on Thomas Kuhn’s critique: if superficial properties are only derivative of micro-structure, they may also have normative grip—but Putnam treats them as epiphenomenal, which they contend is implausible Reddit+2Stanford Encyclopedia of Philosophy+2Reddit+2LiquiSearch+2Reddit+2Reddit+2Reddit.
In summary, Putnam’s influential theories have drawn rigorous philosophical criticism on grounds of meaning, realism, semantics, and mind. Many see his internal realism as vulnerable to relativism or solipsism; semantic holism as epistemologically and communicatively unstable; functionalism as blind to consciousness; and his model‑theoretic argument as inducing indeterminacy. Putnam himself responded to many criticisms, ultimately reshaping his position in the light of them.
