Discourse, Datcourse, when's recess?

How do you know that you know what you know?
Is it frequent retelling that makes it all so?
Is it argumentation that wins a position,
with truth as the prize for the best rhetorician?

Sophistry's misuse has grown so eclectic
I think that of late we neglect dialectic.
Teachers should clearly explain that "to know"
is less about "argue" and more about "show".
