This is an odd extract from the middle of Latour’s Reassembling the Social. The one book where he explicitly addresses just what he means by actor-network theory (ANT). This chapter is written as an imaginary dialogue between Latour and a sociology student who is wondering if ANT is a method for writing up their essay.
