There are four maxims under the Cooperative Principle: the maxim of quantity, quality, relation and manner. They are as follows:

Quantity. (1) Make your contribution as informative as is required (for the current purposes of the exchange). (2) Do not make your contribution more informative than is required.

Quality. Try to make your contribution one that is true. (1) Do not say what you believe to be false. (2) Do not say that for which you lack adequate evidence.

Relation. Be relevant.

Manner. Be perspicuous. (1) Avoid obscurity of expression. (2) Avoid ambiguity. (3) Be brief (avoid prolixity). (4) Be orderly.
