SOBRE EL IUSPOSITIVISMO QUE HEMOS DE DEJAR ATRáS: UNA CRíTICA IUSNATURALISTA A "DEJEMOS ATRáS EL POSITIVISMO JURíDICO" DE ATIENZA Y DE RUIZ MANERO

through the confrontation of atienza's and ruiz manero's thesis proposed in the article called "lets leave legal positivism behind" (dejemos atrás el positivismo jurídico) the author seeks to prove -by answering the following questions: what kind of positivism should be leave behind? why? and how?- that there are weaknesses in iuspositivism to explain the legal reality. this weaknesses are more clear in iuspositivim`s ethical skepticism and as it denies the existence of an anthropological - metaphysical natural law. on the other hand the author shows how those weaknesses are also common in constructivism's attempts to overcome iuspositivism so at the end neither of those conceptual schemes are able to explain human rights as more than just an inexcusable ethical - legal debts based in the ontological dignity of all human beings.
