Cleanliness is an obsession, dirt a fascination. Our disgust is embedded in a personal and cultural system of distinction that helps us navigate the world and discern what might threaten our integrity as bodies or societies. Yet, the aversion to dirt is more than just a protective mechanism. Introducing uncleanliness into design can be enlightening or even revolutionary. As aspiring architects, we know that our profession and its history have always been unclean. We have rejected our masters, dismissed our teachers, and distanced ourselves from our rituals. However, if we become too aware of the dirt our profession produces, we risk erecting hygienic barriers that prevent us from getting our hands dirty.
