David Harvey, undoubtedly the most influential geographer of his generation, combines in his work the study of various disciplines, such as sociology, urban planning, architecture, anthropology, literary studies and political science. This book gathers for the first time fundamental articles, published over three decades, on the tensions between geographical knowledge and political power, and on the capitalist production of space. Classic essays reprinted here include "About history and the current situation of geography", "The geography of capitalist accumulation" and "The spatial solution: Hegel, von Thünen and Marx". Three new chapters represent the author's most recent ideas about cartographic identities and social movements. The persistent questioning by Harvey of declarations of ethical neutrality in the name of science and geography is the guiding thread of the entire book. The author tries to explain the geopolitics of capitalism and base spatial geography on social justice. In the process he analyzes figures overlooked or misrepresented in the history of geography, such as Kant, von Thünen, Humboldt and Lattimore, along with Marx, Hegel, Heidegger, Darwin, Malthus, Foucault and many other authors, thus showing the deep roots and the importance of geographical thinking. At the same time, the revealing observations about current social, environmental and political trends demonstrate the vitality of this thought to understand what the world is like and how it should be.
