Patriotism , as a feeling of exclusive love for one's own people, and as a doctrine of tile virtue of sacrificing one's tranquillity, one's property, and ever, one's life, in defence of one's own people from slaughter and outrage by their enemies, was the highest idea of the period when each nation considered it feasible and just, for its own advantage, to subject to slaughter and outrage the people of other nations.
Leo Tolstoy
