Resumen: Although Haspelmath’s target article does not explicitly say it, the conception oflanguages (and of linguistics as a science) that the author presents is the same asthe one found in Saussure’sCours de linguistique generale(Saussure 1916): Lan-guages are social constructs and linguistics is a social science.1This view is notdemonstrably wrong in and of itself, but I do believe that it is an incomplete andinsufficient foundation on which to build a comprehensive science of language.By establishing a Saussurean notion of languages, Haspelmath effectivelyhints that the naturalistic and internalist conception of language developed bygenerative grammar (GG) does not represent progress in the evolution of ourdiscipline. I will argue here that Haspelmath’s assessment of GG is inadequate,because it is based on a misconception of the scientific nature of GG and of theassumptions under which it operates.
