More Foucaulvian Bliss

"Lastly, the enunciative field involves what might be called a field of memory (statements that are no longer accepted or discussed, and which consequently no longer define either a body of truth or a domain of validity, but in relation to which relations of filiation, genesis, transformation, continuity, and historical discontinuity can be established): thus the field of memory of Natural History, since Tournefort, seems particularly restricted and impoverished in its forms when compared with the broad, cumulative, and very specific field of memory possessed by nineteenth- and twentieth-century biology; on the other hand, it seems much better defined and better articulated than the field of memory surrounding the history of plants and animals in the Renaissance: for at that time it could scarecely be distinguished from the field of presence; they had the same extension and the same form, and involved the same relations."--The Archaelogy of Knowledge & the Discourse on Language, Michel Foucault, 1972
