One version of this oft-quoted adage is:
---
He who knows not, and knows not that he knows not, is a fool. Shun him.
He who knows not, and knows that he knows not is a student. Teach him.
He who knows, and knows not that he knows, is asleep. Wake him.
He who knows, and knows that he knows is wise. Follow him.
Is a child teach him. He who knows not and knows not that he knows not is a fool shun him.

A frame poem is a type of poem where the beginning and ending stanzas are identical or very similar, creating a "frame" for the rest of the poem. The repetition of these stanzas helps to emphasize the central theme or idea of the poem.
