"Further elaboration would, of course, disclose other characteristics of the "author-function," but I have limited myself to the four that seemed the most obvious and important. They can be summarized in the following manner: the "author-function" is tied to the legal and institutional systems that circumscribe, determine, and articulate the realm of discourses; it does not operate in a uniform manner in all discourses, at all times, and in any given cultural it is not defined by the spontaneous attribution of a text to its creator, but through a series of precise and complex procedures; it does not refer, purely and simply, to an actual individual insofar as it simultaneously gives rise to a variety of egos and to a series of subjective positions that individuals of any class may come to occupy."
