Against hard border thinking and traditional notions of sovereignty, this work is an argument for soft borders and transnational citizenship exercised through multiple and overlapping polities: negotiable and fluid spaces of political association. The work does not romanticize movement, but recognizes the cruel grasp of border politics on people's lives. It rejects a notion of sovereignty that fixes political identities into hierarchical geographies of place, facilitating the movement and well-being of some at the expense of others. The argument for soft borders is a plea to reverse the trend of building walls for peace and security and an appeal to open rather close the opportunities and avenues for collective action.
