The question whether semantics is a normative discipline can be formulated as a question about the meaning of the word “means”. If I assert, “The word ‘gatto’ in Italian means cat,” what have I done? The naturalist about meaning claims that I have asserted that a certain natural relation obtains between Italian speakers’ tokens of “gatto” and cats. Or at least, I have asserted something about the way Italian speakers use the word “gatto”, which way presumably has something to do with cats. The normativist claims, on the contrary, that what I have said is that in speaking Italian one ought to use the word “gatto” in a certain way, which way has something to do with cats. What I have done is endorse a certain proposal about how to use the word, which, if accepted, will have normative force.

The proposition expressed by an utterance of a quantified sentence depends on a domain of discourse somehow determined by the context. How does the context of utterance determine the content of the domain of discourse? Many philosophers would approach this question from the point of view of an expressive theory of linguistic communication, according to which the primary function of language is to enable speakers to convey the propositional contents of their thoughts to hearers. This paper argues that from this point of view there is no persuasive treatment of the determinants of the domain of discourse. The argument focuses on an abnormal case in which the domain the speaker has in mind is not evident to the hearer. In this way the question concerning the determinants of the domain of discourse is used to challenge the expressive theory of communication

Language acquisition is often said to be a process of mapping words into pre-existing concepts. If that is right, then we ought to be able to obtain experimental evidence for the existence of concepts in prelinguistic children. One line of research that attempts to provide such evidence is the work of Paul Quinn, who claims that looking-time results show that four--month old infants form “category representations”. This paper argues that Quinn’s results have an alternative explanation. A distinction is drawn between conceptual thought and the perception of comparative similarity relations, and it is argued that Quinn’s results can be explained in terms of the latter rather than the former

A similarity space is a hyperspace in which the dimensions represent various dimensions on which objects may differ. The similarity space theory of concepts is the thesis that concepts are regions of similarity spaces that are somehow realized in the brain. Proponents of such a theory of concepts include Paul Churchland and Peter Gärdenfors. This paper argues that the similarity space theory of concepts is mistaken because regions of similarity spaces cannot serve as the components of judgments. It emerges that although similarity spaces cannot model concepts, they may model a kind of nonconceptual representation.
