  In this section, I will set aside features (i) and (ii) as being  characteristic of any empirical domain: the data are  always finite, and they always underdetermine one's theory. No doubt it's an important problem for epistemologists and  philosophers of science to explain how general theories can  nonetheless be confirmed and believed. No doubt, too, it's an  important problem for psychologists to explain the mechanisms by  which individuals acquire general knowledge about the world on the  basis of their experience. But underdetermination and the finiteness  of the data are everyone's problem: if these features of the language learning situation per se supported nativism, then we should accept  that all learning, in every domain, requires inborn domain-specific  knowledge. But while it's not impossible that everything we know that goes beyond the data is a result of our having domain-specific innate knowledge, this view is so implausible as to warrant no further  discussion here.
