Humans naturally acquire languages that connect meanings with pronunciations. Paul M. Pietroski presents an account of these distinctive languages as generative procedures that respect substantive constraints. Children acquire meaningful lexical items that can be combined, in certain ways, to form meaningful complex expressions. This raises questions about what meanings are, how they can be combined, and what kinds of meanings lexical items can have. According to Pietroski, meanings are neither concepts nor extensions, and sentences do not have truth conditions. He argues that meanings are composable instructions for how to access and assemble concepts of a special sort. More specifically, phrasal meanings are instructions for how to build monadic concepts (a.k.a. mental predicates) that are massively conjunctive, while lexical meanings are instructions for how to fetch concepts that are monadic or dyadic. This allows for polysemy, since a lexical item can be linked to an address that is shared by a family of fetchable concepts. But the posited combinatorial operations are limited and limiting. They impose severe restrictions on which concepts can be fetched for purposes of semantic composition. Correspondingly, Pietroski argues that in lexicalization, available representations are often used to introduce concepts that can be combined via the relevant operations.

This book explores how grammatical structure is related to meaning. The meaning of a phrase clearly depends on its constituent words and how they are combined. But how does structure contribute to meaning in natural language? Does combining adjectives with nouns (as in 'brown dog') differ semantically from combining verbs with adverbs (as in 'barked loudly')? What is the significance of combining verbs with names and quantificational expressions (as in 'Fido chased every cat')? In addressing such questions, Paul Pietroski develops a novel conception of linguistic meaning according to which the semantic contribution of combining expressions is simple and uniform across constructions. Drawing on work at the heart of contemporary debates in linguistics and philosophy, the author argues that Donald Davidson's treatment of action sentences as event descriptions should be viewed as an instructive special case of a more general semantic theory. The unified theory covers a wide range of examples, including sentences that involve quantification, plurality, descriptions of complex causal processes, and verbs that take sentential complements. Professor Pietroski also provides fresh ways of thinking about much discussed semantic generalizations that seem to reflect innately determined aspects of human languages. Designed to be accessible to anyone with a basic knowledge of elementary logic, Events and Semantic Architecture will interest a wide range of scholars in linguistics, philosophy, and cognitive science.

Paul Pietroski presents an original philosophical theory of actions and their mental causes. We often act for reasons: we deliberate and choose among options, based on our beliefs and desires. However, bodily motions always have biochemical causes, so it can seem that thinking and acting are biochemical processes. Pietroski argues that thoughts and deeds are in fact distinct from, though dependent on, underlying biochemical processes within persons.
