Mary Douglas wrote that:‘There is no such thing as absolute dirt; it exists in the eye of the beholder. Dirt offends against order. Eliminating it is not a negative movement, but a positive effort to organize the environment. In chasing dirt, in papering, decorating, tidying, we are not governed by anxiety to escape disease, but are positively re-ordering our environment, making it conform to an idea.’Dirt is a human concept. There is no such thing as dirt in nature. The natural world is neither pure nor dirty. It just is. Everything is simply where it happens to be. Until litter is dropped and houses are built to exclude and chemicals are spilled and smog rises the idea that anything could be in the wrong place is absurd. And being human, dirt is a moral concept. Something that is right or wrong. Organized correctly or not. What can it tell us about ourselves? About order-making, about right and wrong, about 'dirty' people, about racism, and creativity?Then & Now is FAN-FUNDED!
