摘要：This is a comparative study between argumentative strategies used in the Portuguese and Brazilian Constitutional Preambles, from 1976 and 1988, respectively, in order to verify the constructed constitutional ethos . Taking the Constitutional Preamble as an inclusive textual genre (Rastier, 1989), the analysis on the thematic and discursive components (Bronckart, 1999), provides indication to establish a comparative analysis of texts. The results obtained show that, when comparing different historical contexts, the constitutional ethos of the Portuguese Preamble seems to be pedagogical and have a more asymmetrical tone when compared with the Brazilian one, which is more protective.
