"Peterson Martins' operation consists of formalizing the respective translations of the two writers in question in order to construct a meta-theory, an undertaking of his own. This is one of the researcher's innovative traits; he begins by discursively investing the space of the Sertao (Man and Nature) by endowing it with a discourse analogous to the social text of the so-called 'silent majority', from the day he discovered a tradition considered genuine in the engenho of the compadres of his discursive material of the Sertao, he brings to light a Sertao that speaks to them and through their mediation with him."
