David Harvey's persistent challenge to the claims of ethical neutrality on behalf of science and geography runs like a thread throughout the book. He seeks to explain the geopolitics of capitalism and to ground spatial theory in social justice. In the process he engages with overlooked or misrepresented figures in the history of geography, placing them in the context of intellectual history. The presence here of Kant, Von Thunen, Humboldt, Lattimore, Leopold alongside Marx, Hegel, Heidegger, Darwin, Malthus, Foucault and many others shows the deep roots and significance of geographical thought. At the same time David Harvey's telling observations of current social, environmental, and political trends show just how vital that thought is to the understanding of the world as it is and as it might be.
