In Territoriality, Mario Pascalev explores the question: What is the ground of legitimate state jurisdiction over territory? Accounts of state are mainly concerned with the bonds of obligation between a state and its members. However, many individuals are bound by the commands of a state without being its members, hence the notion of territorial authority. Territoriality is examined relative to concepts like sovereignty, citizenship, secession, self-determination, immigration and refugeehood. The author first surveys collectivist and organic theories, such as those of Hobbes and Herder. He then reviews individualist approaches basing territoriality in private property (Locke), individual well-being (Rawls), consent (Beran), and place (Walzer). The flaws of the received accounts of territoriality are demonstrated at length. In the final part, Pascalev develops the novel home theory of territory. A state's jurisdiction over territory stems from its residents' right to home. To support his theory the author examines the unique harms suffered by refugees. Further, the right to home is supported by its importance for personal identity.
