This study makes an attempt to argue for the so-called `Strongest Minimalist Thesis` as an optimal alternative to Chomsky`s (2001, 2004, 2005a, 2005b) Strong Minimalist Thesis. I prove, based on the perspective of the modern biolinguistics, that the innate faculty of language, so far assumed in the Strong Minimalist Thesis, doesn`t exist and, therefore, the narrow syntax must be eliminated from the grammar system just as a major real imperfection. Furthermore, I propose a new grammar framework, that is, the Language Generation System along the line of the Strongest Minimalist Thesis suggested in this study.
