Exploring the Cultural History of Christmas Solstice and Related Holidays

In a recent article in the New York Times, Nicholas Wade reported that the American Anthropological Association had decided “to strip the word ‘science’ from a statement of its long-range plan.” Is this just a reflection of the long standing division between physical and cultural anthropology or is there more here? The revised statement says that “the purposes of the association shall be to advance public understanding of humankind in all its aspects,” a wording that opens the possibility for cultural anthropologists to engage in public advocacy on behalf of cultures they are studying. So, what kind of discipline is anthropology, after all? And, more broadly, should scientists cross the line from research into public advocacy?
