The border phenomena is highlighted by Victor Turner's liminality-concept, and thus prolonged in the imaginable field: semiotics of ritual. The management of thresholds may be operated on several axes; the most crude is exclusion-inclusion, similar to the basic digital on-off (1 - 0); to be a part or not may be seen as the fundamental asset in a society; but as far society is perceived as a rhizomatic conglomerate; rather such than a unitary, or arborescent whole; border-control, so to say, becomes in a paradoxical fashion the central issue.
