Rules for Poets

[Sundae]

I loved it all, except:

Rhymes are appropriate to children's books and high school creative writing assignments. Formulae are beautiful only in mathematics.

Which is wrong. Just plain wrong.
I have read (and posted here) beautiful sestinas - not my own, I don't have the discipline.
And an insistence that free verse is the only valid form of poetry negates many of the other points. And sadly soured me on the rest of it.

Free verse can be beautiful. But it is deceptively artful, and its very simplicity is what fools many would-be poets into thinking they can write.

There is a huge difference between rhyming doggerel and poetry.
And some of the most talented poets I have read employ verse and/ or specific form to great affect.
