Any Literature majors???? I am dumb and need help analyzing this

I have no idea what this means.....

I am writing a scholarly article essay. The one I chose is "Edgar Allan Poe's Aesthetic Theory, the Insanity Debate, and the Ethically Oriented Dynamics of "The Tell-Tale Heart," by Dan Shen

This is the sentence that I am trying to understand

"First, being beautiful is not so much an end as a means for conveying the thematic import of the prose narrative."

And

"Second, if the skill of the work inhibits readers' comprehension of the true import of the narrative, then the skill will be regarded as defensive."
