Must children born with socially challenging anatomies have their bodies changed because others cannot be expected to change their minds? One of Us views conjoined twinning and other abnormalities from the point of view of people living with such anatomies, and considers these issues within the larger historical context of anatomical politics. Anatomy matters, Alice Domurat Dreger tells us, because the senses we possess, the muscles we control, and the resources we require to keep our bodies alive limit and guide what we experience in any given context. Her deeply thought-provoking and compassionate work exposes the breadth and depth of that context–the extent of the social frame upon which we construct the normal. In doing so, the book calls into question assumptions about anatomy and normality, and transforms our understanding of how we are all intricately and inextricably joined.
