The border circumscribes the State. It describes the State. In being its boundary, it determines the State.
Every thing is what it is thanks to its borders. After all, it is they that separate it from another thing. This distinction carries the most important meaning of the concept of the border not just for international law, defense doctrine, or the structuring of a country’s armed forces, but also for philosophy as such. The border is not just an instrument of philosophy, but its essence, seeing as the highest philosophical concept – transcendence -in Latin literally means “that what lies on the far side of the border”.
