SCALING THE "WALL IN THE HEAD"

Costica Bradatan

The Berlin Wall may have been torn down long ago, but many people in Germany still feel divided; the wall is intact in their minds.
Walls protect people not from barbarians, but from anxieties and fears, which can often be more terrible than the worst vandals. In this way, they are built not for those who live outside them, threatening as they may be, but for those who dwell within.
With walls come mental comfort, tranquility and even a vague promise of happiness. Their sheer presence is a guarantee that, after all, there is order and discipline in the world. A wall signifies the victory of geometrical reason over anarchic impulses.

A wall is above all the admission of a fundamental vulnerability.
A wall is always perceived as an invitation. It is a way of putting things in a more tempting light, of making them desirable.
This explains why walls are so attractive and also why they are besieged, eventually torn down and apart. They are just irresistible.
Walls are built for various reasons and they serve different purposes, but their function is always fundamentally the same: to create divisions, to prevent people and ideas from moving freely, and to legitimize differences.

Above all, walls help keep the world alive and history in motion. A wall is always a provocation, and life is possible only as a response to provocations; a world without walls would soon become stale and dry.
