O autor e o anonimato, por Foucalt

Even within our civilization, the same types of texts have not always required authors; there was a time when those texts which we now call "literary" (stories, folk tales, epics and tragedies) were accepted, circulated and valorized without any questions about the identity of their author. Their anonymity was ignored because their real or supposed age was a sufficient guarantee of their authenticity. Text, however, that we now call "scientific" (...) were only considered truthful during the Middle Ages if the name of the author was indicated. (...) In the seventeenth and eighteenth centuries, a totally new conception was developed when scientific texts were accepted on their own merits and positioned within an anonymous and coherent conceptual system of established truths and methods of verification.

At the same time, however, "literary" discourse was acceptable only if it carried an author's name; every text of poetry or fiction was obliged to state its author and the date, place, and circumstance of its writing. The meaning and value attributed to the text depended upon this information. If by accident or design a text was presented anonymously, every effort was made to locate its author. Literary anonymity was of interest only as a puzzle to be solved as, in our day, literary works are totally dominated by the sovereignty of the author.
