What’s an author? Someone who writes a book, right?
Well, according to Michel Foucault, it’s not quite that simple. While one could define an author as “someone who writes,” as I understand Foucault’s argument an author is also a person created, in a sense, by his work rather than the other way around. “Shakespeare,” for example, is both a proper name indicating a specific person, but also has a meaning intimately connected with his work. The meaning of “Shakespeare” would change significantly for society if, say, we learned that it was actually Bacon who wrote the plays traditionally attributed to the Bard.
The argument is interesting, but unfortunately I can’t really speak of it except in general terms.
