This paper develops a critic on International Human Rights departing from the criticism directed to utopian discourses of political organization of society, as both of them share an evolutionist and ethnocentric foundation, namely, the universal and unconditionally valid reason. The idea is to undertake a serious criticism on reason, always potentially dystopian, in order to unravel the colonialist ethos and the civilizing character of current Public International Law leading discourse of Human Rights.
