Foucault concludes that we should, strictly, not speak of the ‘author’
but of the ‘author function’. To be an author is not merely to have a certain factual relation to a text (for example, to have causally 11
produced it); it is, rather, to fulfil a certain socially and culturally defined role in relation to the text. Authorship is a social construction, not a natural kind, and it will vary over cultures and over time.
