Ong’s The Writer’s Audience is Always a Fiction speaks about the relationship or the role of the audience. The audience is an imaginary concept that the writers must come up with while creating a text (similar to the idea that an author isn't real, or the the author is not always there). This concept of "not simply what to say but also whom it say it to: (pg 11), bring up the question of who is the structure of writing created in the first place.
If there is no real audience (speaking of text not oral presentations and stories) and in some stories there is no author than how is there a universal structure of what is a story and who is speaking it and whom are they speaking to? Would it not be easier to write a story as if you were racing it out loud. I know as Ong say "He has to write a book that real persons will buy and read" (pg 10), but what are the limitations of a real audience? It is simple to write for a teacher if they give you directions but what about the audience, the audience that most of us write for, how to we know if and when they are real? Or is all concepts of audience real so you must accommodate to as many people as possible?
