Peter Taylor's Political geography: world-economy, nation-state and locality presents the work of Immanuel Wallerstein to geographers in a clear and accurate fashion, It reconnects political geography and political science, mapping Mackinder onto Spykman and Whittlesey onto Deutsch. It urges that human geography be a historical social science. Elsewhere, Taylor has teasingly averred "that all geography is historical geography", and has argued that the world-systems project speaks to the best of "traditional (that is pre-socialscience) geography" which "left a holistic legacy to geography that was at variance with the growing specialisation in the natural and social sciences". He claims that in its preoccupation with the state "much of modern geography ha[s] in fact abandoned its global heritage" and that he has, therefore, turned from Marxist geography "to embrace an equally rich but alternative geography to be found in Wallerstein's Historical capitalism.
