It is unfortunate that Francis Y. Lin, in ‘Chomsky on the “ordinary language” view of language’ pays little attention to his own remark, ‘Chomsky’s criticisms make us realize that we should not be content with general and vague formulations of convention, ability, and so on. We must make such notions precise and provide details’ Lin speaks so imprecisely and provides so few details of notions on which he relies heavily, such as ‘general learning mechanism’ and ‘sentence frame’, that readers must employ large amounts of guesswork to place even a halfway specific interpretation on his proposals and claims.
