"Death Of The Author" is more like a concept from the field of literary criticism which holds that an author's intentions. and However, biographical facts of the author should hold no weight when coming to an interpretation of his or her writing;hence, that a writer's interpretation of his own work is no more valid than the interpretations of any of the readers. What I think is, books are meant to be read, and so the ways readers interpret them are more important and "real" than the ways writers write them. But of course, text's meaning vary to different reader's interpretation. It would be sloppy and flawed Barthes said if we as readers would to impose a limit on the text by the author's political view, religions, ethnicity, or personal attributes.
Barthes emphasized that the author is merely a "scriptor" that produces and not to explain the work which is "born simultaneously with the text". "Every work is eternally written here and now" meaning to say each reading's original meaning lies exclusively in the language itself, and its impressions on the reader.
However, I've got a question here, how many of us, nowadays, are impressed by the work itself rather than the impression of the author. What do you first look at when you're buying a book? The author's background, status popularity, or the impression of the work?
