> Given the universal role of sharing food as a marker of community and well-documented cases of not sharing food as a marker of social difference -high caste Hindus refusing to eat food touched by low caste Hindus is a classic example-the implicit meaning of the question is, "Are you enough like us that we can get along and develop a social relationship?" In his book _Plagues and Peoples_, which Jared Diamond so liberally imitated, O'Neill argues that the ultimate reason for the Hindu social practices was based on disease. The Dravidians, driven into the South, were likely vectors for tropical contagion, and so when a high caste touched a low caste person or food, the high caste person was required to wash, i.e., to engage in a ritual ablution ceremony. The same epidemiological reasons, masked by tradition, are at work in Jewish kosher and Muslim halal prescriptions about food. Considering that European diseases killed about 90 percent of the Native Americans, one can see the way epidemiology matters to cultures, and is then explained religiously. In my opinion, the disease explanation is a highly effective naturalistic argument for addressing the surface cultural phenomena. Now that Western medicine has spread worldwide, and the human population steadily increased for the first time in history, cultural explanations based on motives ("Can we understand each other's motives?) do come into force, as John suggests. though disease and plagues are the naturalistic root.
