model – a body–biography chain, the biographical trajectory of an individual and the trajectory of their illness are placed alongside each other.

In a second model, multiple biography/identity trajectories are introduced, as a way of recognizing the multiple dimensions of an individual’s life, complicating the understanding of the course of illness in relation to the person who is ill.

In both these models, the problem space is a container space. However, in a third model, the external linear time of the classification system is folded into the model: continuities, discontinuities and layers are introduced into the problem space. In the action of folding the epistemic limit of the classification system across the trajectories, the model becomes expressive; that is, the model acquires inventive methodological potential in the folding of ‘the outside’ of the problem into the ‘inside’. It is encapsulated. As Bowker and Star put it, there is a topology–typology twist: ‘The topology created by the body–biography trajectory is pulled against the idealized, standardized typology of the global classification of tuberculosis, itself a broken and moving target’ (2000: 190).
To return to the vocabulary introduced in the discussion of Rockburne, this model involves the action of folding the external limit of the classification system into the problem. That is, the method of folding changes the problem even as it persists, creating new methodological potential in the process of transformation. In other words, it is not just a problem that is defined in transformation, but the problem and the problem space, as they are compulsively composed together.
In what follows it will be suggested that compositional methodology is concerned with the way in which a problem emerges in the relation between two moments; that is, with the addressing of a method or methods to a specific problem, and the capacity of what emerges in their use to change or transform the problem (Rheinberger 1997). As Nina Wakeford and I (2012) argue, it is the relation between these two moments that makes methods answerable to a problem, and provides the basis of the self-displacing movement or auto-spatialization of a problem. We further argue that the inventiveness of methods is a consequence of the articulation of their double force: their constitutive effects and their capacity to contribute to the generative circulation of the problem. Here I suggest that a compositional methodology acknowledges and exploits the fact that the double force of auto-spatialization does not operate to create a space that contains the problem, but, rather, has as its aim the composition of a problem across a problem space that is itself changing.4 Indeed it is proposed that it is the accomplishment of some kind of continuity and connection in the transformation of a problem that secures epistemological value.

Becoming topological
What the discussion above implies, and the example from Bowker and Star illustrates, is that compositional methodology does not employ a container understanding of problem space but is, rather, concerned with the becoming topological of problem spaces (Lury, Parisi and Terranova 2012). What might this mean?
Topology is commonly described as a mode of analysis that arises from the study of spatial properties that remain invariant under transformation. It is thus a mode of analysis that is concerned with how continuity and change can take place together. Importantly, while it might seem, from this definition, that topology describes spatial properties that exist outside of or are independent of time, just as the concept of the problem space proposed here does not presume a conception of space as container, nor does it assume a container conception of time. As Steven Connor says, ‘Because topology is concerned with what remains invariant as a result of transformation, it may be thought of as geometry plus time, geometry given body by motion’ (http://www.stevenconnor.com/topologies). The claim that problem spaces are ‘becoming topological’ is an acknowledgement of the ways in which the compulsive composition of a problem makes time and space in relation to each other in the organization of continuity in transformation. 5
While some other discussions of methodology employ the vocabulary of topology, the usefulness of the vocabulary of topology for the analysis of social and cultural life has been much debated (Law and Mol 1994, 2002; Thrift 2008; Lury, Parisi and Terranova 2012; Shields 2013; https://culanth.org/fieldsights/series/topology-as-method), with some advising caution on the grounds that topology as an approach has been significantly developed in – and should be confined to – mathematics (Phillips 2013). In developing his geographical analysis of topologies of power, John Allen (2016) disagrees. To do so, he draws on Ian Hacking’s interpretation of the transposition of mathematical terms to other domains. In a discussion which acknowledges the complexities of borrowings between disciplines as well as the variety of uses to which knowledge is put, Hacking says:
It is not so clear whether we are discovering that the second domain has the same structure as the first domain, or whether we are sculpting the second domain so that it comes out shaped like the first. Probably both sorts of things happen. (Hacking 2014: 175 in Allen 2016: 5)
Allen says that he is not bothered with policing the borrowings between disciplines, but instead prefers to mobilize a cross-disciplinary understanding of topology – that is, a concern with a form of relations that remains continuous in transformation – and that is the approach adopted here (see also https://www.theoryculturesociety.org/interview-with-celia-lury-luciana-parisi-and-tiziana-terranova-on-topologies). Following this approach, and as above, a compositional methodology addresses the becoming topological of problem spaces by exploring the continuity in (trans)form(ation) of problems across problem spaces. Indeed, it aims to describe and interrogate how the making of such continuities enables epistemological values to be established. However, with Hacking’s analysis in mind it is important to remember that, like the drawing that requires a support to make itself, so does the becoming topological of problem spaces require a (material-semiotic) support. No methodology can operate in the abstract, and so the book is concerned not only with the composition of problem spaces but also with epistemic infrastructure.
The term ‘epistemic’ is used to signal that what is at issue in this new empire of truth is the nature of understanding, interpretation, explanation, justification and belief rather than knowledge as such.6 As Karin Knorr Cetina puts it:
Epistemic cultures are cultures of creating and warranting knowledge. This is what the choice of the term ‘epistemic’ rather than simply ‘knowledge’ suggests’ … [i]t brings into focus the content of the different knowledge-oriented lifeworlds, the different meanings of the empirical, specific constructions of the referent (the objects of knowledge), particular ontologies of instruments, specific models of epistemic subjects. (2007: 363–4)
Alongside ‘epistemic’, the term ‘infrastructure’ highlights the ways in which knowledge-making requires and installs material supports in the world, what Knorr Cetina calls knowledge settings, the ‘whole sets of arrangements, processes and principles that serve knowledge and unfold with its articulation’ (2007: 361–2), including ‘buildings, bureaucracies, standards, forms, technologies, funding flows, affective orientations, and power relations’ (Murphy
