This article seeks to make a novel contribution in the context of the controversy surrounding the Museum of Memory and Human Rights (MMDH) in Chile: should the MMDH (or should it not) include in its museography the period before September 11, 1973—i.e., the context for the coup d’état? I defend the thesis that the MMDH can integrate a contextual dimension—without betraying its mission, vision, and function—as long as it responds to an approach to the notion of a context-without-causality. In my opinion, the main problem with criticism from the political right—which accuses the museum of not fulfilling its educational mission because it decontextualizes the coup d’état—is that it responds to a causal vision of the notion of context, which leads it to insurmountable contradictions. If, thanks to a well-thought-out museography, the concept of noncausal contextualization were successfully implemented, this would not create a contradiction within the museum, but could even favour it. The conviction that the coup d’état and its atrocities have no causes or antecedents, and cannot have them, reinforces the educational mission of the MMDH.
