This article aims at some problems of the traditional poliarchic republicanism in Brazil, searching solutions for its difficulties on the issues of representation and participation. Not meant as a normative proposal, the article just enquiries alternatives which, at this moment, can not be more than probings. The core of these enquiries points out to the formation of a "complex solidarity" in contemporary Brazil.
