Abstract
The paper applies the theoretical frameworks of epistemic injustice and narrativist philosophy of history to read the process of re-signification of an event that took place in a prison in the city of Buenos Aires, Argentina, in 1978, called “Massacre in the Seventh Ward” or “Mutiny of the Mattresses”. By looking into this case, we explore the exercise of epistemic resistance through category expansion, drawing on the most recent developments on hermeneutical injustice as a deficiency in the application (and not only in the content) of the available concepts. This allows us to identify the selected case as an example of hermeneutical injustice, and to highlight some characteristics of such injustice that remain under-analysed in the specialised literature, linked to agency, temporality, and the concrete forms adopted by resistance. Among the latter, we highlight the role that can be played by the exercise of what in philosophy of history has been called the “practical past”: an intervention in the dispute of meanings about the past, born out of an explicit commitment to the present. Finally, the conclusions present some caveats to be considered in the study of epistemic injustice in the context of institutions such as prisons.
