Quote #7
Stop your fighting and abuse! / You expound just how you used / to educate the men of old; / you, the modern teacher's goal. / After judging the pros and cons, the boy will choose the school he wants. (933-938)
The Chorus Leader gets involved in couples counseling for Better Argument and Worse Argument. His scolding puts a finger on a central difference between the two "men": one privileges what used to be, and one is all about what's new and sexy (idea-wise).
Quote #8
Very well; I'll now describe what education used to be, / back when I spoke truth and flourished, back when decency was in vogue. (961-962)
Better Argument launches into his case for his ideas, which were "in vogue" back in the good old days. Apparently, "truth" and "decency" were popular then, and they're not now.
