Describing observations during her fieldwork at a Dutch university hospital, Annemarie Mol argued that the disease “atherosclerosis” was not one, but multiple - every discipline involved in the care and treatment of the disease figured it differently, and no disease exists separately to its figuration through some scientific paradigm. One moment that has stayed with me is her description of how the identification of an objective existence of the disease is understood to happen under microscopic observation. This is one example of how situated practice makes the disease “cohere” in contingent circumstances involving social and technological systems of many kinds - Mol does not just observe that the disease is figured differently depending on someone’s discipline, but also that despite this incommensurable difference, sociotechnical practice brings a coherent view of the disease into being as required.
