Abstract
The article is about the moral importance of language as a necessary condition to determine one´s individual moral status. The problem, therefore, concerns the analysis of the justification and consistency of this moral attributive aspect of language. The main theoretical support to deconstruct this view will be the argument of species overlap, commonly called the "marginal cases" argument. Even if it is assumed that non-human animals are not linguistically competent, there would be a logical inconsistency in admitting human beings incapable of language into the moral community at the same time that non-human animals are excluded.
