In this question, I asked about how meaning gets into a work if not intended by the author. In researching that question, I ran across mention of "authorial intent". In reading about it, I learned that it went through phases of being very important to analysists and other phases where it did not matter at all. In modern academic literary analysis, how much of a role does it play? Is it only to backup previously made claims or does it ever form the center of fundamental arguments?
