Putnam

Works

Papers rather than a system, and the system he built he later dismantled.

• “The Meaning of ‘Meaning’” (1975) contains the Twin Earth argument and the division of linguistic labour.
• Reason, Truth and History (1981) sets out internal realism, the brains-in-a-vat argument, and the case against a God's-eye view.
• Representation and Reality (1988) refutes functionalism, a position he had invented two decades earlier.
• The Collapse of the Fact/Value Dichotomy (2002) makes the case that thick ethical concepts cannot be factored into a descriptive part and an evaluative one.

Central ideas

Three, and the third is the one that bears on this work's method.

• Semantic externalism: two speakers in identical mental states can mean different things, because reference is fixed by the environment and by the community. What a word picks out is not settled by what its user has in mind.
• The division of linguistic labour: a speaker can use elm and beech correctly without being able to tell them apart, because someone in the community can. Reference is a social achievement rather than an individual one.
• The collapse of the fact and value dichotomy: thick concepts such as cruel, brave, or generous do descriptive and evaluative work simultaneously and cannot be factored. There is no fully non-evaluative description of conduct waiting underneath.

Distinctive vocabulary

Three terms whose loose use loses the arguments.

• Externalism, in his sense: a thesis about what determines reference. Not a claim that speakers do not know what they mean.
• Internal realism: truth as idealised rational acceptability, with no God's-eye view. A position he held for roughly fifteen years and then abandoned, so it is not simply his view.
• Thick concept: one that describes and evaluates at once. Not a vague concept and not a loaded word.

Debates and disagreements

The changes of position are themselves one of the debates.

• Whether the repeated revisions show intellectual honesty or the absence of a stable position. Both readings are held in the literature, and a reader has to decide which Putnam is being cited before the question even arises.
• Internal realism was pressed from both sides as unstable: either it collapses into the relativism he denied or into the metaphysical realism he rejected. He eventually abandoned it.
• Whether thick concepts can be factored after all. The fact and value argument is influential and the separability question is still open.
• Whether the Twin Earth intuitions are robust; cross-cultural work has found the responses vary.

Intellectual relationships

He argued with almost everyone in the lineage, including himself.

• Quine, in this same lens lineage, supplies the holism he accepted while rejecting the behaviourism and the indeterminacy conclusions drawn from it.
• Kripke developed rigid designation and externalism in parallel, and the two arguments are usually taught together.
• Dummett's anti-realism is the interlocutor internal realism was formulated against.
• Rorty is the pragmatist he argued with continuously, each accusing the other of the position he had spent his career refusing.
• Bernard Williams supplied thick ethical concepts, and Murdoch, a reference elsewhere in this work, made an adjacent case that moral vocabulary is not separable from moral vision.

How it changes this reading

Putnam is named in the lineage of the Epistemological lens.

• Externalism bears on reading a record: what an utterance referred to is not settled by what its speaker had in mind, so recovering what someone meant and recovering what they said are different operations with different evidence.
• The fact and value collapse names a tension in this work's own method rather than resolving one. This work prefers descriptions calibrated to specific exchanges over characterological ones, and Putnam's argument is that no description of conduct is fully non-evaluative — there is no neutral layer underneath to retreat to.
• That makes the calibration preference a choice about WHICH evaluation a description carries and how answerable it stays, rather than a move from evaluation to neutrality. Stating it that way is more accurate than the tidier version.
• It is not evidence about what anyone meant or valued.

Useful comparisons

The lens names four references who each say the knower's interior is not sufficient.

• Michael Polanyi: tacit knowing — what is known subsidiarily cannot be made focal without collapsing the performance.
• W. V. O. Quine: holism — no belief faces experience alone.
• Hilary Putnam: externalism — reference is fixed outside the head, by the world and by the community.
• Lorraine Code: situation — who a knower is, and what standing they have, bears on what they can know and be believed about.

Where the ideas meet

All four refuse the self-sufficient knower.

• None treats knowing as a matter of an individual mind checking propositions against the world unaided.
• All four hold that something outside the knower's interior is doing epistemically necessary work.
• Each treats the conditions of knowing as part of epistemology rather than as background.

Where they part

Four things are meant by outside the head, and they are not versions of each other.

• Polanyi's outside is the performance and its particulars; Putnam's is the environment and the expert community. One concerns competence, the other reference.
• Quine's holism is about how confirmation distributes across a system of beliefs; Putnam accepted it and rejected the behaviourist framework it came wrapped in, so citing the two together requires saying which part.
• Code's situated knower concerns power and standing — whose knowledge is credited — which is a political claim where Putnam's is a semantic one.
• And Putnam differs from himself across decades more than he differs from some of these, which is why a date is not optional.

Limits

• Externalism concerns what fixes reference and says nothing about what any speaker intended or understood.
• The fact and value argument shows that descriptions carry evaluation; it does not show which evaluation is correct, and cannot settle any particular description.

Criticisms

The objections include one that makes citing him hazardous.

• The repeated changes of position mean that a claim attributed to Putnam is frequently one he had abandoned by the time it was quoted.
• Internal realism was unstable enough that he gave it up, and it is still widely cited as his view.
• The Twin Earth intuitions are less robust cross-culturally than the argument assumes.
• Whether thick concepts resist factoring remains contested, so the fact and value collapse is a strong position rather than a settled result.

Common misreadings

Four uses this placement does not license.

• Citing Putnam without specifying the period, which is the commonest error and often attributes a view he refuted.
• Using externalism to argue that speakers do not know what they mean; the thesis is about what determines reference, not about self-knowledge failing.
• Using the fact and value collapse to license evaluation presented as description, when the argument is that the two cannot be separated rather than that the distinction does not matter.
• Reading internal realism as relativism, which he spent a decade denying.

What remains outside this idea

• It cannot establish what anyone meant, referred to, or valued.
• It cannot settle whether any particular evaluative description is correct.
