We are beset by unspoken rules. As a result, we learn to find consensus in nots and to seek refuge in don'ts. A taboo is a restriction invented and agreed upon by a social group that maintains stability (disciplinary order) but also induces transgressions (the possibility of an avant-garde). Taboos structure our thinking and frame our discussions. In architecture, taboos create an operative way of thinking about and making architecture through unspoken agreement.
