Individual and Nation

Over the centuries, the basic political unit has expanded from City, to Province or County, to Nation, and currently, to Planet.  At each transition, there is a dissolution of the smaller unit, followed by an integration of an aggregate of the constituents of the recently dissolved units.  So, for example, Modern Political Philosophy, spanning Hobbes, Locke, Spinoza, and Rousseau, most notably, is fundamentally Nationalistic.  In other words, their models represent not the Individual per se, but the Individual qua product of Medieval Provincial polities, transitioning to Modern National ones.  Likewise, Kant and Marx signal the transition to what can be termed Contemporary Planetary models.
