Gricean Maxims
A sentence can be true in court and false in the room. Paul Grice’s 1975 essay “Logic and Conversation” explains the trick: people do not hear only words, they hear words against an assumed contract of cooperation. Break that contract in a visible way, and the listener starts calculating what you meant without saying it.
The Four Maxims
Grice called the hidden contract the Cooperative Principle: make your contribution fit the conversation’s purpose. Under it sit four maxims.
| Maxim | Plain test | What breaks when it is flouted |
|---|---|---|
| Quantity | Did you say enough, and not too much? | Evasion, hints, strategic omission |
| Quality | Do you have grounds for saying it? | Irony, lying, legal phrasing |
| Relation | Is it relevant? | Topic shifts, diplomatic non-answers |
| Manner | Is it clear, brief, and orderly? | Ambiguity, comedy, bureaucratic fog |
The key word is “flouted,” not “violated.” If I ask whether a candidate can lead a team and you answer, “He is always punctual,” I infer the missing negative because your answer is too small for the question. That inference is not in the sentence. It lives in the gap between the sentence and the expected answer.
Why It Matters
Contracts, comedy, diplomacy, and family arguments run on implicature. “The payment was processed” may not mean “the money arrived.” “That is an interesting proposal” may mean “no.” A stand-up comic can obey grammar while breaking Relation or Manner, forcing the audience to solve the missing step in half a second.
This is why Grice belongs near concept information theory. Claude Shannon’s 1948 theory counts signal, noise, and entropy without asking what a message means. Grice starts where Shannon stops: the listener treats missing information as information.
What Is Contested
The maxims are a clean model, not a full theory of human language. Dan Sperber and Deirdre Wilson’s 1986 Relevance Theory argues that listeners do not check four rules one by one; they search for a high-relevance interpretation at low processing cost. Stephen Levinson’s 2000 work pushes the other way, showing how many default meanings are carried by ordinary phrasing before the listener does much conscious work.
The live question is not whether implicature exists. It does. The question is how much of it comes from general reasoning, how much comes from learned linguistic defaults, and how much comes from culture-specific conversational training.
Cross-Realm Bridge
Gricean maxims are small-scale concept game theory. Every utterance is a move made under partial information. The speaker chooses how much to reveal; the listener models what a cooperative speaker would have said instead.
That also makes them useful for reading concept fermi paradox. “We see no aliens” is a literal observation. The implied claim, that silence means absence, depends on hidden maxims about detectability, effort, and relevance across civilizations. Language and astronomy meet at the same caution: absence of a signal is not always signal of absence.
An Open Question
If large language models learn implicature from text alone, do they learn Grice’s cooperative contract, or only the statistical shadow of it? The difference matters for concept ai alignment, where a technically true answer can still be the wrong answer to the human question.

Abhishek's take
What grabs me about Grice is that it makes politeness look like computation. A buyer, a lawyer, or a diplomat can move a decision by choosing what not to say, and the listener still does the missing arithmetic. The dangerous part is that the same machinery powers jokes and half-truths.
