Is this a real question?What makes the author’s interpretation of a work more legitimate than anyone else’s?

If it is, that is like a stranger asking you about your childhood home. One that you grew up in from birth to 18. Then hearing you recall stories about your childhood home. Then the stranger turns around to another person and starts explaining "what you really meant." Your story of the pipes creaking turns into you being afraid of ghosts. Your stories of a backyard garden become your desire to protect the environment. Your story of mom cooking cinnamon rolls in the morning becomes why you have a sweet tooth.
While some of these may be true, it would be much more genuine for the stranger to say: "He told me this story of creaking pipes keeping him awake. He said it happened in the winter. And that sometimes it was loud. I wonder if he was scared of the noise? I wonder if he thought it was something else?"
See how that doesn't take on an authoritative tone, but rather one of inquisitiveness. The original comment was about a professor dismissing the author's actual interpretation. It's nice to analyze an author's works, especially as a collection. But, as I stated earlier:
Your interpretations of your house are the most valid. It is the primary source. Historians even need primary sources to prove a theory. Secondary sources are just that - secondary.But if you are going to speak as an authority on a subject, one should be very aware and knowledgeable of the original source. And one should try to use it for their interpretation.
