Current textbooks in formal semantics are all versions of, or introductions to, the same paradigm in semantic theory: Montague Grammar. Knowledge of Meaning is based on different assumptions and a different history. It provides the only introduction to truth- theoretic semantics for natural languages, fully integrating semantic theory into the modern Chomskyan program in linguistic theory and connecting linguistic semantics to research elsewhere in cognitive psychology and philosophy. As such, it better fits into a modern graduate or undergraduate program in linguistics, cognitive science, or philosophy. Furthermore, since the technical tools it employs are much simpler to teach and to master, Knowledge of Meaning can be taught by someone who is not primarily a semanticist. Linguistic semantics cannot be studied as a stand-alone subject but only as part of cognitive psychology, the authors assert. It is the study of a particular human cognitive competence governing the meanings of words and phrases. Larson and Segal argue that speakers have unconscious knowledge of the semantic rules of their language, and they present concrete, empirically motivated proposals about a formal theory of this competence based on the work of Alfred Tarski and Donald Davidson. The theory is extended to a wide range of constructions occurring in natural language, including predicates, proper nouns, pronouns and demonstratives, quantifiers, definite descriptions, anaphoric expressions, clausal complements, and adverbs. Knowledge of Meaning gives equal weight to philosophical, empirical, and formal discussions. It addresses not only the empirical issues of linguistic semantics but also its fundamental conceptual questions, including the relation of truth to meaning and the methodology of semantic theorizing. Numerous exercises are included in the book.

This paper is principally devoted to comparing and contrasting poverty of stimulus arguments for innate cognitive apparatus in relation to language and in relation to folk psychology. These days one is no longer allowed to use the term ‘innate’ without saying what one means by it. So I will begin by saying what I mean by ‘innate’. Sections 2 and 3 will discuss language and theory of mind, respectively. Along the way, I will also briefly discuss other arguments for innate cognitive apparatus in these areas

The topic of this paper is the semantic structure of belief reports of the form 'a believes that p'. it is argued that no existing theory of these sentences satisfactorily accounts for anaphoric relations linking expressions within the embedded complement sentence to expressions outside. a new account of belief reports is proposed which assigns to embedded expressions their normal semantic values but which also exploits frege's idea of using senses to explain the apparent failures of extensionality in the reports

Allow me to recapitulate some territory that will be familiar to most readers. Here is how the problem of mental causation has typically been set up since shortly after the onset of non-reductive physicalism. It is now widely assumed that the realm of the physical is causally closed: every physical event has a complete physical cause, a cause that is sufficient for the event’s occurrence. This apparently leaves us with a limited number of options concerning psychological causation, none of which appear hugely attractive. Either: (a) the psychological is epiphenomenal and can have no causal impact on the physical, or (b) the psychological is identical with the physical, or (c) thoughts and actions are all over-determined, each one having two distinct sufficient causes. Option (b) subdivides into two further options. Either (b1) the psychological reduces to the physical and every psychological property is identical with some physical property, or (b2) token psychological events are identical with or constituted from token physical events but psychological properties are not identical with physical properties. (b1) is widely held to be inconsistent with the multiple realisation of the psychological by the physical. And (b2) appears to bring us back to the original problematic, with the properties as the locus of tension. If one event causes another it does so in virtue some of its properties and not others. If I throw a stone at a window and the window breaks, it is because the stone was hard and heavy that it broke the window and not, say, because it was grey and millions of years old. The properties in virtue of which an event has a particular effect are typically called the ‘causally efficacious properties of the cause with respect to the effect.’ Suppose, then that token neural event causes an action. We can ask ‘Does it do so in virtue of its physical properties or its psychological properties?’ and we are back to choosing between options (a) and (c) or returning to (b1)..

Please allow me to recapitulate some territory that will be familiar to most readers. Here is how the problem of mental causation has typically been set up since shortly after the onset of non-reductive physicalism. It is now widely assumed that the realm of the physical is causally closed. This means that the probability of any event’s occurring is fully determined by physical causes, and physical causes alone. There is no space in the physical causal nexus for any non-physical event to exert any influence

The paper begins with the assumption that psychological event tokens are identical to or constituted from physical events. It then articulates a familiar apparent problem concerning the causal role of psychological properties. If they do not reduce to physical properties, then either they must be epiphenomenal or any effects they cause must also be caused by physical properties, and hence be overdetermined. It then argues that both epiphenomenalism and over‐determinationism are prima facie perfectly reasonable and relatively unproblematic views. The paper proceeds to argue against Kim’s (Kim, 2000, 2005) attempt to articulate a plausible version of reductionism. It is then argued that psychological properties, along with paradigmatically causally efficacious macro‐properties, such as toughness, are causally inefficacious in respect of their possessor’s typical effects, because they are insufficiently distinct from those effects. It is finally suggested that the distinction between epiphenomenalism and overdeterminationism may be more terminological than real.
