The Moral of the Poem:
It is usually thought that great art suffers, if its didactic purpose is over-emphasized.

In such a poem, even the didactic element, which may ordinarily be counted as a blemish, has all the fascination of a charm that has been superadded. Far from detracting from the superb artistic excellence of the poem, the moral that is preached
