City of Extremes is a powerful critique of urban development in greater Johannesburg since the end of apartheid in 1994. Martin J. Murray describes how a loose alliance of city builders—including real estate developers, large-scale property owners, municipal officials, and security specialists—has sought to remake Johannesburg in the upbeat image of a world-class city. By creating new sites of sequestered luxury catering to the comfort, safety, and security of affluent urban residents, they have produced a new spatial dynamic of social exclusion, effectively barricading the mostly black urban poor from full participation in the mainstream of urban life. This partitioning of the cityscape is enabled by an urban planning environment of limited regulation or intervention into the prerogatives of real estate capital.

Combining insights from urban studies, cultural geography, and urban sociology with extensive research in South Africa, Murray reflects on the implications of Johannesburg’s dual character as a city of fortified enclaves that proudly displays the ostentatious symbols of global integration and the celebrated “enterprise culture” of neoliberal design, and as the “miasmal city” composed of residual, peripheral, and stigmatized zones characterized by signs of a new kind of marginality. He suggests that the “global cities” paradigm is inadequate to understanding the historical specificity of cities in the Global South, including the colonial mining town turned postcolonial megacity of Johannesburg.

Much of the South African government’s response to crime—especially in Johannesburg—has been to rely increasingly on technology. This includes the widespread use of video cameras, Artificial Intelligence, machine-learning, and automated systems, effectively replacing human watchers with machine watchers. The aggregate effect of such steps is to determine who is, and isn’t, allowed to be in public spaces—essentially another way to continue segregation.

In The Infrastructures of Security, author Martin J. Murray concentrates on not only the turn toward technological solutions to managing the risk of crime through digital (and software-based) surveillance and automated information systems, but also the introduction of somewhat bizarre and fly-by-night experimental “answers” to perceived risk and danger. Digitalized surveillance is significant for two reasons: first, it enables monitoring to take place across wide "geographical distances with little time delay"; and second, it allows for the active sorting, identification, and "tracking of bodies, behaviors, and characteristics of subject populations on a continuous, real-time basis." These new software-based surveillance technologies represent monitoring, tracking, and information gathering without walls, towers, or guards.

 
French psychoanalyst Jacques Lacan has been a major influence on a wide range of twentieth-century thought, even as the breadth, complexity, and obscurity of his work has intimidated students and deterred casual readers. That situation hasn’t been helped by uneven translations into English that have led to a popular conception of his intellectual enterprise that can at times be profoundly mistaken.
 
In this brief, clearly written introduction to Lacan and his work, Martin Murray presents an up-to-date survey of his key concepts, their development, and their influence on fields such as anthropology, linguistics, and philosophy. Arguing strongly that we should move beyond the traditional focus on Lacan’s early work, which favored a linguistic approach, Murray offers instead a more comprehensive overview of the whole arc of Lacan’s thought. The result is a rigorous, yet accessible, account of one of the key intellectual figures of the twentieth century.
