Abstract for “Implicit knowledge and linguistic rules” – Natalia Hickman

It is commonly objected to the view that speakers possess implicit knowledge of a grammar or semantic theory that it depends on the unwarranted assumption of isomorphism between abstract structures that characterise languages, and psychological structures that are causally explanatory of language use and understanding. On the other side of the fence, a number of philosophers have urged that intentional linguistic behaviour demands a rationalising explanation in terms of linguistic (especially semantic) knowledge. Each of these contentions has been developed without engagement with the other; this paper draws the consequences of bringing them into proper contact.
