Discourse, the sweeter banquet of the mind. - discourse

A discourse is "a language or system of representation that has developed socially in order to make and circulate a coherent set of meanings about an important topic area."

A good discourse is that from which nothing can be retrenched without cutting into the quick.

Translation: Discourses are tactical elements or blocks operating in the field of force relations; there can exist different and even contradictory discourses within the same strategy; they can, on the contrary, circulate without changing their form from one strategy to another, opposing strategy.
