- The usual linguistic meaning of what is said.
- Contextual information (shared or general knowledge).
- The assumption that the speaker is obeying what Grice calls the cooperative principle.
Conversational maxims and the cooperative principle
The success of a conversation depends upon the various speakers' approach to the interaction. The way in which people try to make conversations work is sometimes called the cooperative principle. We can understand it partly by noting those people who are exceptions to the rule, and are not capable of making the conversation work. We may also, sometimes, find it useful deliberately to infringe or disregard it - as when we receive an unwelcome call from a telephone salesperson, or where we are being interviewed by a police officer on suspicion of some terrible crime.
Paul Grice proposes that in ordinary conversation, speakers and hearers share a cooperative principle. Speakers shape their utterances to be understood by hearers. The principle can be explained by four underlying rules or maxims. (David Crystal calls them conversational maxims. They are also sometimes named Grice's or Gricean maxims.)
They are the maxims of quality, quantity, relevance and manner.

The principle can be explained by four underlying rules or maxims. (David Crystal calls them conversational maxims. They are also sometimes named Grice's or Gricean maxims.)
They are the maxims of quality, quantity, relevance and manner.
- Quality: speakers should be truthful. They should not say what they think is false, or make statements for which they have no evidence.
- Quantity: a contribution should be as informative as is required for the conversation to proceed. It should be neither too little, nor too much. (It is not clear how one can decide what quantity of information satisfies the maxim in a given case.)
- Relevance: speakers' contributions should relate clearly to the purpose of the exchange.
- Manner: speakers' contributions should be perspicuous: clear, orderly and brief, avoiding obscurity and ambiguity.
Grice does not of course prescribe the use of such maxims. Nor does he (I hope) suggest that we use them artificially to construct conversations. But they are useful for analysing and interpreting conversation, and may reveal purposes of which (either as speaker or listener) we were not previously aware. Very often, we communicate particular non-literal meanings by appearing to “violate” or “flout” these maxims. If you were to hear someone described as having “one good eye”, you might well assume the person's other eye was defective, even though nothing had been said about it at all.
