--- title: List and multiplicity (Mol and Law) --- A list doesn’t have to impose a single mode of ordering on what is included in it. Items in the list aren’t necessarily responses to the same questions but may hang together in other ways, for instance socially, because a list may be the result of the work of di√erent people who have each added something to it. Yet it remains open, for a list di√ers from a classification in that it recognizes its incompleteness. It doesn’t even need to seek complete- ness. If someone comes along with something to add to the list, something that emerges as important, this may indeed be added to it.
