For the record.

Barad explains that apparatuses mark (or create) boundaries - they are "boundary-drawing practices" (2007, 206) - and that apparatuses are discursive practices that produce "objects" and "subjects" (2007, 148). Barrett, however, in his paper I Humanness as Performance i challenges their definition and offers the following descriptor: 'archaeology is the examination of historical conditions with reference to surviving material residue' (1). Contemporary archaeological theory has seen a shift from exploring how archaeology should be practiced - that is to say, how we should do archaeology - to another equally fundamental question: what is archaeology?.
