ENDuring the first Lithuanian independence, Lithuanian philosopher Stasys Šalkauskis elaborated an idea of Lithuania linked to the peculiar geo-political and historical situation of the “Lithuanian nation”. The idea of boundary can be considered the focus of this elaboration linking the different parts of the nation–people and ‘cultural classes’- to the world’s unity. The inclusiveness of the idea of border gives a possibility to preserve national characters and to relate the nation with diversity. In a context of political conflicts, as it was in the interwar period, this model represents a challenge of nationalism and a proposal for an open nation.
