This book uses mathematical models of language to explain why there are certain gaps in language: things that we might expect to be able to say but can't. Lucas Champollion offers a theory that unifies the concepts of aspect, plural and mass reference, measurement, and distributivity, to account for these gaps.This book uses mathematical models of language to explain why there are certain gaps in language: things that we might expect to be able to say but can't. For instance, why can we say I ran for five minutes but not *I ran all the way to the store for five minutes? Why isfive pounds of booksacceptable, but *five pounds of booknot acceptable? What prevents us from saying *sixty degrees of waterto express the temperature of the water in a swimming pool whensixty inches of watercan express its depth? And why can we not say *all the ants in my kitchen are numerous? The constraints on these constructions involve concepts that are generally studied separately: aspect, plural and mass reference, measurement, and distributivity. In this book, Lucas Champollion provides a unified perspective on these domains, connects them formally within the framework of algebraic semantics and mereology, and uses this connection to transfer insights across unrelated bodies of literature and formulate a single constraint that explains each of the judgments above.1.
