In the twists & turns of the argument of Whittling, Whistling, I'm actually trying (among other things) to make room in the "theory" for modes of didactic, satiric poetry. Discursiveness, direct address. It may not seem that way... I may not have been very clear.
The idea is that these particular forms of poetry (along with all the other forms & modes) reflect the theatricality of poetry in general. I'm saying poetry & poets are inherently dramatic (hence the emphasis on those attributes noted by Aristophanes). That's why I call poetic language itself the main character, the protagonist : an exaggeration, meant to underline how the medium shapes the message.
