The notion of measurement plays a central role in human cognition. We measure people’s height, the weight of physical objects, the length of stretches of time, or the size of various collections of individuals. Measurements of height, weight, and the like are commonly thought of as mappings between objects and dense scales, while measurements of collections of individuals, as implemented for instance in counting, are assumed to involve discrete scales. It is also commonly assumed that natural language makes use of (...) both types of scales and subsequently distinguishes between two types of measurements. This paper argues against the latter assumption. It argues that natural language semantics treats all measurements uniformly as mappings from objects (individuals or collections of individuals) to dense scales, hence the Universal Density of Measurement (UDM). If the arguments are successful, there are a variety of consequences for semantics and pragmatics, and more generally for the place of the linguistic system within an overall architecture of cognition.

A comprehensive one-year graduate (or advanced undergraduate) course in mathematical logic and foundations of mathematics. No previous knowledge of logic is required; the book is suitable for self-study. Many exercises (with hints) are included.

Structures for Semantics offers an advanced course in logical and mathematical techniques and structures that are used in semantics, in relation to their semantic applications. The book helps students with a background in semantics to develop their skills of formalization and it makes research in semantics accessible. Workers in other disciplines will use it to discover more about the role of formal modelling in current semantic research, and about semantics itself. Following a chapter on logic and set theory there are (...) three parts of chapters: two pairs of chapters on partial order and equivalence relations in relation to semantic analyses of tense, partial information and vagueness; two chapters on methods for creating ordered structures in relation to intervals, events, and the semantics of change; two chapters on lattices and Boolean algebras in relation to types for noun phrases and verbs, and the semantics of plurals and mass nouns. For upper-level undergraduate students and graduate students in semantics: theoretical linguists, logicians, philosophers of language, computer scientists interested in natural language semantics.

Comparative constructions allow individuals to be compared according to different properties. Such comparisons form two classes, those that permit direct, comparisons and those that only allow indirect comparisons. Traditionally, these two types of comparisons have been associated with an ambiguity in the interpretations of the comparative and equative morphemes. In this thesis, I propose that there is no such ambiguity. The interpretations of the comparative and equative morphemes remain the same whether they appear in sentences that compare individuals directly or (...) relative to two separate scales. To develop a unified account, I suggest that all comparisons involve a scale of universal degrees that are isomorphic to the rational numbers between 0 and 1. All comparative and equative constructions are assigned an interpretation based on a comparison of such degrees. These degrees are associated with the two individuals being compared. Crucial to a unified treatment, the connection between individuals and universal degrees involves two steps. First individuals are mapped to a value on a primary scale that respects the ordering of such individuals according to the quality under consideration. Second, this value on the primary scale is mapped to a universal degree that encodes the value's relative position with respect to other values. It is the ability of iv the universal degrees to encode positions on a primary scale that enables comparative and equative morphemes to either compare individuals directly or indirectly. A direct comparison results if measurements such as seven feet participate in the gradable property. Such participation can sometimes result in an isomorphism between two primary scales and the ordering of measurements in a measurement system. When this occurs, comparing positions in the primary scales is equivalent to comparing measurements. If this type of isomorphism cannot be established then the sentence yields an indirect comparison.
