"Many scholars believe that visual mental imagery plays a key role in reasoning. In Space to Reason, Markus Knauff argues against this view, proposing that visual images are not relevant for reasoning and can even impede the process. He also argues against the claim that human thinking is solely based on abstract symbols and is completely embedded in language. Knauff proposes a third way to think about human reasoning that relies on supramodal spatial layout models, which are more abstract than pictorial images and more concrete than linguistic representations. He argues that these spatial layout models are at the heart of human thought, even thought about nonspatial relations in the world. For Knauff the visual images that we so often associate with reasoning are only in the foreground of conscious experience. Behind the images, the actual logical work is carried out by reasoning-specific operations on these spatial layout models. Knauff also offers a solution to the problem of indeterminacy in human reasoning, introducing the notion of a preferred layout model, which is one layout model among others that has the best chance of being mentally constructed and thus guides the further process of thought. Knauff's "space to reason" theory covers the functional, the algorithmic, and the implementational level of analysis and is corroborated by psychological experiments, functional brain imaging, and computational modeling." -- Publisher's description.

Black and white Americans have occupied separate spaces since the days of "the big house" and "the quarters." But the segregation and racialization of American society was not a natural phenomenon that "just happened." The decisions, enacted into laws, that kept the races apart and restricted blacks to less desirable places sprang from legal reasoning which argued that segregated spaces were right, reasonable, and preferable to other arrangements. In this book, David Delaney explores the historical intersections of race, place, and the law. Drawing on court cases spanning more than a century, he examines the moves and countermoves of attorneys and judges who participated in the geopolitics of slavery and emancipation; in the development of Jim Crow segregation, which effectively created spartheid laws in many cities; and in debates over the "doctrine of changed conditions," which challenged the legality of restrictive covenants and private contracts designed to exclude people of color from white neighborhoods. This historical data yields new insights into the patterns of segregation that persist in American society today.

Henri Lefebvre has been celebrated as one of the most influential social theorists of the twentieth century. Understanding Henri Lefebvre places Lefebvre in his historical and intellectual context and analyzes the extraordinary range of his work, across politics, philosophy, history, literature and culture. Particular emphasis is given to Lefebvre's trilogy of inspirational thinkers-Hegel, Marx and Nietzsche; his links to contemporaries such as Heidegger, Axelos and the Situationalists; and his critiques of existentialism and structuralism. Analysis of his writings on cities are balanced with those on rural communities, the production of space connected to ideas of time and history, and everyday life linked to the festival and cultural revolution. Understanding Henri Lefebvre offers the most wide-ranging and reliable account of this central theorist available
