This book explores our long, complex and at times paradoxical relationship with both the reality of "dirt", and the idea of dirtiness. The writing is witty, but at times quite academic; if I'd tagged this I'd have tagged it under popular anthropology/sociology. The authors examine both "clean dirt" and sewage-related dirt, and look into how the concept of dirtiness has become embroiled in both our attitudes to sex and in the tropes of racism. It's all fascinating and at times uncomfortable stuff.
The illustrations are thoroughly esoteric; from filth-related Victorian engravings to a mini-graphic novel, they repay close attention. But - surprisingly in a book which, no matter how entertaining, has a serious side -there is no index.
