A new themed volume on ‘Disease avoidance: from animals to culture‘ in the Philosophical Transactions of the Royal Society B: Biological Sciences provides some food for through when read against Mary Douglas’s Purity and Danger. Douglas insists that we not read food taboos and other cleanliness rituals as medical-materialistic (ie, Jews don’t eat pork because of the pig’s ambiguous place in the animal kingdom at the time Leviticus was written, not because of intuitive notions of Trichinosis). This edited volume does just that. It looks at a broad range of disease-avoidance and treatment behaviors such as avoidance, grooming, quarantine, medicine, stigmatization, the emotion of disgust and care of the sick in terms of medical materialism. Yet it also also theorizes cultural change through disease avoidance, disgust, and stigmatization:

“Disease burden may be a powerful and relatively unrecognized force in human cultural evolution. Historically, emotions such as disgust and fear have been co-opted for broader goals—such as promoting bodily hygiene and the use of soap in the early twentieth century [2], for campaigns against smoking, and more recently against fatty and sweet foods. Unfortunately, this process of moralization, which involves yoking the emotion of disgust to particular behaviours or groups of individuals (e.g. smokers), has also been used for malicious political ends by labelling particular ethnic groups as lice or vermin, for example.” (From the Introduction)

I invite readers interested in the social and cultural aspects of “dirt,” disgust, and stigmatization to read this volume. Lately, I have been trying to reconcile Mary Douglas’ work with more overtly physiological-material definitions and understandings of dirt, pollution and the taboo. Medicine, pollution engineering, toxicology, and evolutionary biology all propose different notions of material-human relationships than Douglas’ “matter out of place,” to the effect that some nuance her work, some can be explained by it, and others negate it. I look forward to any comments or guest posts that do the same.
