 Already in the nineties, Oscar Nudler began to develop a view of the dynamics of science in terms of conflicts (1990). This view became a well-articulated model based on what he called “controversy space” (Nudler 2002, 2004): a dynamic structure composed of inter-related controversies, with a “focus”, composed by the issues that are the main object of the disagreements, and a “common ground”, which consists of the commitments not subject to discussion within the controversy space. Controversy spaces typically change by re-focalization which occurs when certain assumptions move from the common ground to the focus. This model was successfully applied to different scientific cases, such as the origins of chaos theory, the debate about the relations between chemistry and physics, the origins of molecular biology, and the development of twentieth century American linguistics, among others (see Nudler 2011).
