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

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.

Discourse may want an animated "No"
To brush the surface, and to make it flow;
But still remember, if you mean to please,
To press your point with modesty and ease.

Your fair discourse hath been as sugar,
Making the hard way sweet and delectable.
