Peirce

Works

A vast unpublished corpus, read almost entirely through editors.

• The Essential Peirce (two volumes) is the modern chronological selection and the responsible way in.
• The Collected Papers (1931–1958) is how the twentieth century met him, arranged thematically by editors into a system he never published.
• “The Fixation of Belief” and “How to Make Our Ideas Clear” (1877–1878) are the pragmatist essays, and the pragmatic maxim comes from the second.
• The late sign taxonomies, running to dozens of classes, are largely unusable and are part of what makes the corpus hard to cite.

Central ideas

Four, and the second is what this work borrows.

• The triadic sign: sign, object, interpretant. The third term is not an interpreter but another sign, which is why interpretation continues rather than arriving — what he called unlimited semiosis.
• Icon, index, symbol: a sign relates to its object by resemblance, by real existential or causal connection, or by convention. An index — a footprint, a symptom, a weathervane, a trace — is connected to what it signifies rather than standing for it by agreement, and most actual signs are mixtures.
• Abduction: inference to an explanatory hypothesis, distinguished from deduction and induction. It is the only form that generates new ideas, and its output is a candidate to be tested rather than a conclusion.
• Fallibilism and the community of inquiry: no belief is beyond revision, and truth is characterised as what inquiry would converge on in the long run rather than as correspondence available now.

Distinctive vocabulary

Three terms with exact senses that loose use destroys.

• Index: a sign connected to its object by real existential or causal connection. Not an indicator, not a measure, and not an index in the reference-book sense.
• Interpretant: the further sign a sign gives rise to. Not an interpreter and not an interpretation someone performs.
• Abduction: hypothesis generation as a form of inference. Not deduction, not induction, and not a demonstration.

Debates and disagreements

Two are live, and one is about how much of him is his.

• Whether abduction is a form of inference at all or a description of how hypotheses occur to people. His own accounts shifted across his career, and the question is unresolved in philosophy of science.
• Whether truth as the final opinion of an indefinitely extended community has any operational content, or is an idealisation that does no work in a particular inquiry.
• How much of the systematic Peirce is editorial. The corpus is enormous and largely unpublished in his lifetime, and the thematic arrangement of the standard edition imposed an architecture he did not.

Intellectual relationships

The most consequential relationship in this lineage is one that never happened.

• Saussure, in this same lens lineage, developed a dyadic semiology contemporaneously and independently. Neither read the other, and the difference between two terms and three is the deepest division in the field that followed.
• James and Dewey are the pragmatist inheritance; he renamed his own position pragmaticism specifically to separate it from James's version.
• Eco and Sebeok built the Peircean semiotic tradition and are how most readers reach him.
• The philosophy of science literature on inference to the best explanation is where abduction was taken up and disciplined.

How it changes this reading

Peirce is named in the lineage of the Semiotic lens.

• The index is the load-bearing borrowing. Much of what a record contains is indexical — something was written, so someone wrote it — while much of what a reading wants from it is symbolic or iconic, and the two are different kinds of sign with different warrants. Keeping them apart is exactly the discipline this work needs.
• The limit of the index is the useful part: it establishes that a connection existed and says nothing about what the connection was. A trace guarantees a cause without identifying it.
• Abduction names what the readings in this work actually are. They are inferences to explanatory hypotheses, which on his own account are candidates for testing rather than results — so calling them abductions is more accurate than calling them findings.
• The interpretant supplies a semiotic version of the unfinishedness argued for elsewhere here: a reading gives rise to further signs rather than terminating.
• It is not evidence about what any particular sign meant.

Useful comparisons

The lens names four references and three of them descend from the other one.

• C. S. Peirce: a triadic sign including its object, with icon, index and symbol as modes of relation.
• Ferdinand de Saussure: a dyadic sign of signifier and signified, arbitrary by definition, with the referent bracketed out.
• Roland Barthes: myth and connotation, developed from the Saussurean side.
• J. L. Austin: speech acts and felicity conditions, from ordinary-language philosophy rather than from semiotics at all.

Where the ideas meet

All four deny that meaning sits inside a thing.

• None treats meaning as a property an item carries on its own.
• All four hold that signification requires a system, a relation, or a set of conditions.
• Each treats interpretation as constrained rather than free.

Where they part

The split in this lineage is the deepest one in the field.

• Peirce's sign has three terms and includes the object; Saussure's has two and brackets the referent entirely. Barthes descends from Saussure, so three of the four members sit on one side of that division and one does not.
• The index has no counterpart in Saussure at all, whose signs are arbitrary by definition. An indexical reading of a trace cannot be conducted in Saussurean terms, which matters because a record is full of traces.
• Austin comes from a different tradition again and asks what an utterance DOES rather than how a sign means, so citing the lens as one semiotics runs three programmes together.

Limits

What this reference can carry here is narrow, and the index's limit is the sharpest of them.

• An index establishes that a connection existed and not what it was. A trace guarantees a cause and does not identify one.
• Abduction produces hypotheses. Treating an abductive reading as established inverts the one thing he was clearest about.
• A theory of signs establishes nothing about what any particular sign meant to anyone.

Criticisms

The objections are about the corpus as much as the theory.

• The systematic Peirce is substantially an editorial construction from unpublished manuscripts, so citing a settled position is riskier than it looks.
• The late sign taxonomies proliferated past any use and are generally set aside even by sympathetic readers.
• Truth as the final opinion of an ideal community has no operational content for any actual inquiry.
• Whether abduction is inference or psychology is unsettled, and his own accounts of it are not consistent across his career.

Common misreadings

Four uses this placement does not license.

• Using index loosely for any indicator or sign, which loses the requirement of a real causal or existential connection.
• Treating an abduction as a demonstration rather than as a hypothesis to be tested.
• Reading the triad as the signifier-and-signified pair with a third term added; the difference is that his sign includes its object.
• Citing unlimited semiosis as a licence for any reading, when the point is that interpretation continues rather than that it is unconstrained.

What remains outside this idea

• It cannot establish what any sign meant, or to whom.
• It cannot convert a trace into knowledge of what produced it.
