Does Propriety a Better Poet Make?

Does propriety a better poet make-
Where principles are as by God begot
Within recesses deep where one might take
The musing inspiration from and plot?

Or is it skill and will and wicked dye
That sink into the canvas'd page aframe-
That have aught to share but a holy cry-
Which makes a poet, though morally maim?

Are both- scribing their words- Poetry's heir
So that neither virtue nor vice opposed
Might blemish all their written pages fair-
Where enmity of claim aren't presupposed?

Or will poetry's Muse come choose her heirs
Dividing with stained sickle wheat from tares?
