This is a catalogue essay with images of work created for the Metro Musings Exhibition (2015), held at the Rautenbach Hall, University of Pretoria. The publication was published as part of the African Capital Cities Project, funded by the Andrew W Mellon Foundation. The essay draws on the work of Elizabeth Grosz and Deleuzian becoming in understanding how subjects are constituted through their interaction with human and non-human forces in their urban setting.

The ruinous vitalism of the urban form: ontological orientations in inner-city Johannesburg2017 •
Abstract This paper is based on ethnographic fieldwork, conducted between 2011 and 2016, in unlawfully appropriated buildings, or the ‘dark buildings’, of inner-city Johannesburg in which thousands of the city’s marginalized black populations live, including many cross-border migrants. It argues that responses to traumatic and debilitating events, including fires and building collapse, invoke an unstable ontological multiplicity oriented around the fragility of the urban form. ‘Ruinous vitalism’ refers to this instability and malleability of urban infrastructures, the scars and traces these leave and the capacities for social relations and regeneration they provoke. Ontologies here are not thought of in terms of sets of pre-existent beliefs or essences, but rather modes of orientation. Ontological orientations involve attempts to interpret, stabilize and reconfigure relations of existence through embodied and material practice; they also encompass wider social and metaphysical relations through which meaningful personhood can endure. In particular, the boundaries between insiders and outsiders are formed around the unstable materialities of the city. Furthermore, these orientations are not ahistorical, but emerge in relation to the historical and contemporary conditions and inequalities of the post-apartheid city; they traverse the attempts by municipal agents and private developers to contain and control urban space.

Urban Design in the Global South: Ontological Design in Practice (2014)2014 •
Ontological design is a nascent practice that implies a paradigm shift in the theory and practice of architecture, urban design and design in general; it cannot be appealed to as if it were an independent agency or off-the-shelf method. It requires the ontological transformation of us as designers. This essay proceeds by first outlining an approach to ontological difference. It goes onto to paint some rough pictures of the various ontological intersections in three Global Cities—Port Moresby, Dili and Johannesburg. This is done in ways that intentionally emphasizes problems and contradictions. This is done to set the scene for the last section of the essay: a discussion of how, using Port Moresby as an example, the city might be configured differently and more positively. Establishing the foundations of ontological design requires attention to basic ontological categories—that is, fundamental categories of existence and how they are lived across human history. For the purposes of establishing a starting point, we use the terms of the ‘constitutive abstraction’ approach, a form of ‘engaged theory’ that begins with the ontological categories of space, time, embodiment, knowing and performing as foundational to being human (James 2006). Each of these terms summarizes the very different ways in which we live spatially and temporally as embodied persons, performing sociality in relation to others and nature, and knowing in different ways what it means to do so. The concept of ‘ontological formations’, or ‘ways or being’, is intended to name different formations in which a particular set of orientations or valences to basic categories of being, such as temporality and spatiality, frame the dominant practices and meanings of social life.

On the Edge of Scrutinizing and Reproducing Urban Imaginations of Johannesburg2015 •
Over the last 5 years, intelligence on new technologies in communication and mobility seems to have advanced while at the same time, its usage seems to have increased tremendously in the urban spaces of big cities in South Africa. The presence and diversity of mobile especially cell phones for almost everyone in the city is an indicator of the escalation of the use of communication technology in the urban spaces of South Africa’s big cities. This trend seems to have had an impact on urban space. This paper argues that the emergence of technologically driven dialogues between the empowerment of people, town planning power and political power is what determines the form and function of urban space. In other words, it’s about power. This paper has also attempted to trace the power dialogues in urban space to the 1800’s and has used Pretoria- now City of Tshwane as a case study.

Problem statement: The contemporary metropolis faces two sometimes conflicting roles through the discursive and paradigmatic developments in the world: role-playing at the national/ transnational level and meeting local-level expectations. Similarly, and because of the multiplicity and diversity of relations between these two levels and the different subjects underlying these dual roles, the ontological definition of "place" in this metropolis has to be changed. Here, we are considering a conception of the existence of the place in which it can adopt the aforementioned complex communications and the probable and unseen conflicts within it as a quasi-object (the contained), and manage it as a quasi-subject (container) and accommodate it. Research objective: Redefining the ontology of place in such a way that it can mediate as an intermediate layer, i.e. "the urban-relational" between these two role-playing levels: place as a quasi-object / place as a quasi-subject. Research method: The research paradigm focuses on post-positivist schemata and the poststructuralism approach, and follows the ontology of place as an urban-relational entity in today's metropolis. The method of this research is qualitative and its type is developmentalexploratory. This research seeks to present a new ontology of the concept of place in metropolis through the review of library documents and the description, analysis, and extension of ideas and theoretical approaches. Conclusion: place as a quasi-object/ quasi-subject must be a communicative mediator (the urban-relational) between the two different levels of role-playing, thereby regulating the communications of multiple and sometimes heterogeneous subjects and adjust conflicts between them. The mediation coordinates of this urban-relational intermediate layer allow for four spectral states for the level of place-ness: towards minimal place-ness; towards maximal place-ness; towards some extent of place-ness; the probability of anarchy and disorder.

The curated exhibition Metromusings (2013) in the Rautenbach Hall of theDepartment of Visual Arts of the University of Pretoria engaged thematically with the notion of capital cities. Recoding a diverse and massive - ‘invisible’ - archive of stories and experiences, the exhibition offered visual representations of reflections on urban environments (and Pretoria in particular) that have been shaped out of fragments of trajectories and alterations of spaces. Metromusings endeavoured to present a visual mapping of the social and political power geographies and complexities that dominate cities and how urban culture can be voiced, claimed, negotiated and contested. A defining question in the context of the city was how space can be translated into place.
This text summarises an ongoing research project about small cities which are usually not included in the research agenda on global cities. We aim at bridging between research focused on global or world cities and that on smaller or secondary cities in Africa. Arguing against the view of smaller Third World cities as mere towns, as “not yet cities”, and therefore irrelevant to world city theorizing, this project intends to develop an alternative analytical approach to think differently about these small cities in the South. Basing ourselves on ongoing ethnographic research in Ghana, Congo and Namibia, we argue that these secondary cities are fully urban in that they generate networks and practices that extend far beyond the local limits of these cities and their immediate rural hinterland, and that they often manage to do so in more successful ways than their larger counterparts. At the same time these secondary cities are sites in which new and different forms of urban life and imagination are being shaped, offering the perspective of an alternative African urban future.
