Review date: 30 September 2026. Status: bounded, exploratory review; no claim of an exhaustive worldwide systematic review or preregistered protocol.
The public objective is to end imprisonment for words. That objective needs an argument about coercion in addition to an account of what an inscription is. The literature examined here does not make the two questions interchangeable. Communication may participate in an action without its written marks becoming the person, event or object described. Conversely, recognising a communicative act supplies no automatic reason for confinement.
The terminology of this review receives no exception. Evidence, intention, declaration, harm, law, method, necessity and freedom remain expressions in a report. Their use proposes distinctions and directs inspection; it does not put the named circumstances into the file. The same applies to every accusation and every exculpatory conclusion.
What was actually searched and read
Twelve recorded queries were executed through one public web search engine in three batches on 30 September 2026. The complete search responses contain 50, 54 and 51 URL records: 155 visible records, each screened at title/snippet/source-type level. These are not the search engine’s total hits, and no per-query count is available from the combined batches. Eight works were selected from that search; four existing project sources were reopened. Twelve works enter the review. The record-level outcomes were 8 inclusions, 76 alternative manifestations/discovery records, 30 secondary or index records, 18 off-topic records, 5 unread full-text candidates and 18 deferred candidates. The 5 unread candidates include two distinct Nagin records; this is a record count, not a claim of five independently read works.
The exact queries, returned records, decisions and access attempts are in literature_search.json. Queries targeted Frege, Austin-related speech acts, Grice, Searle, Langton, legal treatment of speech, and reviews of deterrence, incapacitation and community sanctions. The Volokh query mistakenly specified 2014; the retrieved article is dated 2005. The Searle query targeted 1976; the accessible source actually reviewed is his 1975 book chapter. These discrepancies are retained in the log.
Selection favoured author-written academic texts and authored official reviews, with directly relevant passages publicly available in English or English translation. Criteria were operationalised during the review, not preregistered. All 155 visible records received a decision, but only included passages were substantively assessed. Eighteen potentially relevant titles were deferred through purposive prioritisation; their exclusion does not mean their arguments failed. Search snippets and inaccessible files are never treated as inspected content. Complete relevant text for Schauer, Nagin’s journal article and the updated Campbell review was not obtained; their arguments are not filled in from reputation or abstracts.
This is a systematic search record followed by a structured, purposively bounded review. It uses no subscription database, systematic non-English search, citation-network census, independent second screener or meta-analysis. Availability and prioritisation can bias the selected material. The included prison literature concerns broader offending; no included study estimates the causal effectiveness of imprisoning people specifically for communication. Three punishment items contain reviews or summaries, not three independent experiments. Read scopes and exact locators are deliberately narrower than the files available.
Extraction: twelve sources, different roles
| ID | Work; passages inspected | Bounded source account |
|---|---|---|
| S26 | Austin, 1962, selected anthology extracts, printed 55–59 | A sentence may participate in an action whose success depends on participants, procedure and circumstances. |
| S31 | Frege, 1892, Black translation, PDF 1–4 | Sign, sense and reference are distinguished; quotation can concern signs themselves. |
| S32 | Grice, 1957, printed 377–379, 383–384, 386–388 | Communicative meaning involves intention and recognition, with contextual qualifications. |
| S33 | Searle, 1975, printed 344–347, 350–351, 358–361 | Declarations can produce institutional status; factual judicial claims remain assessable. |
| S34 | Langton, 1993, printed 293–304 | Speech-act subordination is conceptually defended; justification of censorship remains a further question. |
| S27 | Solan, 1995, printed 1069–1072 | Linguistics can improve explanations without monopolising interpretation. |
| S28 | Kranzlein/Schneider/Tobia, 2024,§3.1/Table 1 | Court language can be annotated by terms, definitions, quotations, sources and interpretive arguments. |
| S35 | Volokh, 2005, selected 1328–1329, 1334–1335, 1348 | Relabelling speech as conduct is inadequate; particular speech restrictions may nevertheless be justified. |
| S36 | NRC, 2014, chapter 5, selected 133–144, 155–156 | Deterrence and incapacitation differ; effects vary by policy and targeted population. |
| S37 | Gendreau/Goggin/Cullen, 1999, Method/Results/Table 1/Discussion | Longer custody did not reduce recidivism; the weighted custody/community comparison was null. |
| S38 | NIJ,May 2016, both PDF pages | Certainty receives greater deterrent weight than severity; punishment and incapacitation remain distinct purposes. |
| S11 | Human Rights Committee, 2011,§§22, 25, 34–35, 47, 50–52 | Restrictions require justification; imprisonment guidance in §47 concerns defamation, not every offence. |
Primary URLs, local full texts, provenance, access records, qualifications and adverse points appear in literature_sources.json and review_matrix.json. Availability of a full file does not imply complete reading. The Austin source is an anthology excerpt; Frege is an English reproduction; Searle and Langton required OCR of scans. OCR assists location and does not replace the source image where spelling matters.
Original synthesis: three burdens that remain distinct
The following conclusions are this research’s argument, not statements that the twelve sources jointly prove.
A burden of attribution. A record needs a supported relation to a person and a situation before an accusation can concern that person. An anonymous sentence, an attributed sentence and an authenticated communication are different evidentiary positions. A published quotation and the communication being quoted may have different participants and purposes. The boundary does not decide among those positions. It prevents one position from silently taking another’s place.
A burden of characterisation. The strongest objection to the project says that some communication constitutes an act. A qualified official can dismiss an employee or issue a decision through an utterance. It would be a mistake to answer that objection by insisting that signs are causally inert. The relevant distinction is between an occurrence of signs and an account of what someone did through them. A supported account may identify participants, authority, delivery, circumstances and applicable conventions. It remains an account that can be challenged.
Searle’s difficult case sharpens this distinction: a declaration may settle institutional status while leaving its factual assertion open to assessment[S33, pp. 360–361]. For this project, institutional finality cannot substitute for factual support or for a reason to imprison. Nor does the project deny that institutions can operate. Its demand is that operation, correctness and justification stay separately inspectable. Langton’s conceptual account and her expressly acknowledged censorship gap reinforce the need to identify the additional step[S34, pp. 299–300].
A burden of sanction. Even a supported interpretation of a communicative act does not determine the response. A justification might invoke protection, deterrence, incapacitation or deserved punishment. Those are different proposed reasons with different questions. A poor marginal-deterrence finding cannot settle the moral argument about desert. A claimed incapacitation benefit cannot establish attribution retrospectively. A review of imprisonment for offences in general cannot establish a measured effect for communication offences.
The political proposal remains absolute within its stated subject: end confinement as a response to producing or using communication, including cases where an accusatory characterisation is supported. The literature review does not deduce that rule from nonidentity or announce that it already exists in law. The research’s separate normative argument supplies four authored reasons: a response with a specified target, revisability, equal opportunity to challenge, and the cost of granting the power to confine. That argument retains the bar when narrower measures fail or imprisonment might provide additional prevention. The resulting residual risk has not been measured by this corpus. Neither calling the rule absolute nor calling a situation dangerous supplies the missing justification; both proposals remain open to disagreement.
What the review changes for public action
The practical contribution is a set of separable public demands: disclose the relevant record and attribution chain; distinguish quotation, proposed reading and independently supported circumstances; name the criterion applied; show how the material meets it; explain the particular coercive response. A category name cannot do the work of all five.
There is a serious adverse case. Recipients can be intimidated, deprived of effective opportunities to speak or placed in relations of coercion through communication. Some targeted incapacitation policies may prevent serious offending[S36, pp. 155–156]. These concerns require a public response. The absolute proposal retains its refusal of custody for communication, and proposes that protection should be assessed through the same explicit chain, with measures such as contact restrictions, safeguarding, remedies and response opportunities compared on their actual operation. This review does not establish that any one alternative always succeeds.
The review closes three shortcuts: an inscription does not acquire the named status merely through a reading; communicative participation is not itself a prison sentence; an institutional label is not its own justification. It also leaves a defined evidence gap: comparative, speech-offence-specific evaluation of imprisonment and less coercive responses. Filling that gap requires separate empirical work, not another authoritative word added to this article.
