It would seem that the author’s name, unlike other proper names, does not pass from the interior of a discourse to the real and exterior individual who produced it; instead, the name seems always to be present, marking off the edges of the text, revealing, or at least characterizing, its mode of being. The author’s name manifests the appearance of a certain discursive set and indicates the status of this discourse within a society and a culture. It has no legal status, nor is it located in the fiction of the work; rather, it is located in the break that founds a certain discursive construct and its very particular mode of being. As a result, we could say that in a civilization like our own there are a certain number of discourses that are endowed with the “author-function”, while others are deprived of it. A private letter may well have a signer_ it does not have an author; a contract may well have a guarantor_ it does not have an author. An anonymous text posted on a wall probably has a writer_ but not an author. The author-function is therefore characteristic of the mode of existence, circulation, and functioning of certain discourses within a society.
