The wall belongs to “half-wits,” to the “ill-adapted,” to the “rebellious,” to the simple, to all those of heavy heart. The wall is truancy’s blackboard. The wall, safe haven for what is forbidden, gives a voice to all those who would, without it, be condemned to silence. Branded with the mark of evil, eroticism and violence can there be given free rein. But surely the anguish of touching upon “taboos,” of transgressing them, alerts us to the fact that the wall conserves something “sacred” It exorcises Purifies, liberates all that lies repressed, from all that oppresses.
