Abstract

Legal positivism, as a set of theses necessarily defended or assumed by those that fly its colors, has being commonly criticized with bases in errors or myths, constituting a “straw man” of what this philosophical tradition is. In this paper, we proport to rescue the central theses of positivism, defining them by the artifact thesis and the separability thesis, with contingent presence of the source thesis and/or the conventionality thesis. With that settled, we go on to demonstrate that the idea of a “outdated” positivism, unable to account for legal principles, is false, as well as the picture of a legal positivism that implies some specific interpretative methodology, such as textualism or originalism. Through this article, we expect to clear or even recover the debate about legal positivism, specially in Brazil, reviving the theses that are really defended by this century-old philosophical tradition, distancing ourselves from the “straw man” created.
