What is a poem with noble feeling?

It was Plato's argument that poems without noble feelings ought to be banned from a Republic. Sentiments of the poet is a major factor deciding the worthiness and quality of a poem, especially now. Noble emotions governed Chaucer, Spenser, Milton and Tennyson. That was why they could create lofty poems. Reading a poem written from noble emotions leaves us elated. Generally speaking, a poem that leaves us elated will be with a noble feeling.
