This article aims to answer a precise query: who has the power and the authority to
speak about the past in different discursive registers on memory and history? The experience
is constructed by discursive protocols and operations. Then how these protocols can exclude
subaltern population from the ―authorized‖ code to speak? This question is not answered here
―rethorically‖ or philosophically but through two empiric cases: the first is a testimony of a
South African writer denouncing his imposibility to speak about his own history. The other
one, the word of one of the leaders of the Argentine Indegenous Movement.
