The Brazilian translation (2015) of Patrick Sériot's Preface to the French translation (2010) of Marxism and the Philosophy of Language (MPL) provides a good opportunity to discuss this work and its relevance for the field of Human Sciences, considering different possible interpretations. In this sense, this work presents a discussion on questions that deserve, in our opinion, to be addressed both in Sériot's work (taken as an example of MPL's interpretation) and in Voloshinov's.
