This paper defends an orthodox model of the linguistic intuitions which form a central source of evidence for generative grammars. According to this orthodox conception, linguistic intuitions are the upshot of a system of grammatical competence as it interacts with performance systems for perceiving and articulating language. So conceived, probing speakers’ linguistic intuitions allows us to investigate the competence–performance distinction empirically, so as to determine the grammars that speakers are competent in. This model has been attacked by Michael Devitt in his recent book and a series of papers. In its place, Devitt advances a model of linguistic intuitions whereby they are speakers’ theory-laden judgements about the properties of languages. In this paper, I try to make clear the rationale behind the orthodox model and the inadequacies of Devitt's model

Noam Chomsky, the founding father of generative grammar and the instigator of some of its core research programs, claims that linguistics is a part of psychology, concerned with a class of cognitive structures employed in speaking and understanding. In a recent book, Ignorance of Language, Michael Devitt has challenged certain core aspects of linguistics, as prominent practitioners of the science conceive of it. Among Devitt’s major conclusions is that linguistics is not a part of psychology. In this thesis I defend Chomsky’s psychological conception of grammatical theory. My case for the psychological conception involves defending a set of psychological goals for generative grammars, centring on conditions of descriptive and explanatory adequacy. I argue that generative grammar makes an explanatory commitment to a distinction between a psychological system of grammatical competence and the performance systems engaged in putting that competence to use. I then defend the view that this distinction can be investigated by probing speakers’ linguistic intuitions. Building on the psychological goals of generative grammar and its explanatory commitment to a psychological theory of grammatical competence, I argue that generative grammar neither targets nor presupposes non-psychological grammatical properties. The latter nonpsychological properties are dispensable to grammarians’ explanations because their explanatory goals can be met by the theory of grammatical competence to which they are committed. So generative grammars have psychological properties as their subject matter and linguistics is a part of psychology

There is a popular idea that a shift from a Principle of Charity to a Principle of Humanity, as famously advocated by Richard Grandy, offers considerable advantages in constructing theories of meaning for natural languages. My claim is that Grandy’s case for the superiority of the Principle of Humanity does not tell against the Principle of Charity developed by Donald Davidson. The paper outlines important developments in Davidson’s Principle of Charity, and his refinement of the Principle of Charity that he found in Quine’s writings. I argue that Grandy’s criticisms, whilst sound against the Quinean principle he had in mind, do not extend to Davidson’s refined Principle of Charity. I then raise two further issues that face advocates of the Principle of Humanity as an improvement on Davidson’s Principle of Charity.
