Grice (1967) proposed the Cooperative Principle (CP) and four conversational
maxims. The CP runs as follows: make your contribution to what is required at the stage
at which it occurs, by the accepted purpose or direction of the talk in which you are
engaged; to put it in another way we assume that in a conversation, all participants,
regardless of their cultural background, will cooperate with each other when making
their contributions, dice then broke this principle down into four maxims, which go
towards making a sneaker's contribution to the conversation "cooperative".
