This book examines and proposes a solution to the knowability paradox. The paradox derives from the proof that if all truths are knowable, then all truths are known, which was first published by Frederic Fitch in 1963. It identifies two problems created by Fitch’s proof: a perceived anti-realism and the paradox created by the proof. It is argued that although the two problems are related, a defence against the threat to anti-realism is no solution to the paradox. The neo-Russellian theory of quantification is considered the only acceptable solution to the paradox, since no other approach offers any hope of addressing the fundamental paradoxicality involved in asserting a lost logical distinction between actuality and possibility.Less

Plural predication is a pervasive part of ordinary language. We can say that some people are fifty in number, are surrounding a building, come from many countries, and are classmates. These predicates can be true of some people without being true of any one of them; they are non-distributive predications. Yet the apparatus of predication and quantification in standard modern logic does not allow a place for such non-distributive predicates. This book explores the enrichment of modern logic with plural predication and quantification. We can have genuinely non-distributive predication without relying on singularizing procedures from set theory and mereology. The fundamental ‘among’ relation can be understood in a way that does not generate any hierarchy of plurals analogous to a hierarchy of types or a hierarchy of higher-order logics. Singular quantification can be understood as a special case, with the general type being quantifiers that allow both singular and plural quantification. The ‘among’ relation is formally similar to a ‘part of’ relation, but the relations are distinct, so that mass quantification and plural quantification cannot be united in the same way that plural and singular are united. Analysis of singular and plural definite descriptions follows, with a defence of a fundamentally Russellian analysis, but coupled with some new ideas about how to be sensitive to the role of context. This facilitates an analysis of some central features of the use of pronouns, both singular and plural.Less

This book contains a number of chapters on the Roman economy which discuss methods of analysing the performance of the economy of the Mediterranean world under Roman imperial rule in the period c.100 BC to AD 350 through quantification. It focuses on the methods and problems involved in identifying and analyzing the characteristics of economic integration, growth, and decline in this period. In particular, it attempts to suggest how a complex and diverse economic world can be better understood by using quantifiable and proxy data to measure these processes in different parts of the Mediterranean world. The data are drawn from both documentary and archaeological sources, and the book emphasizes the need to draw together different kinds of written and artefactual evidence and to describe the ways in which they complement each other. This approach is pursued in a series of analyses of approaches specific economic sectors: demography, urbanization and settlement patterns, the agrarian economy, patterns of trade and commerce, mining, metal supply, and coinage. The book offers a survey of the opportunities for advancing understanding of the economic and technological development of the Roman empire by using the tools and techniques of economic history and statistical analysis.Less

This volume is a collection of studies focusing on population and settlement patterns in the Roman empire in the perspective of the economic development of the Mediterranean world c. 100 BC to AD 350. The analyses offered here highlight the issues of regional and temporal variation: Italy, Spain, Britain, Egypt, Crete, Asia Minor from the Roman republic to the early Byzantine period. Although they are by no means exhaustive, the contributions to this volume sketch out the varied landscapes in which the many general issues raised need to be further analysed. The relationship between urban settlements and their environs and the economy of rural settlements in or beyond those environs is crucial, and the authors suggest particular aspects that might repay analysis: the physical size of settlements and the relationship between size, location, and distribution. The chapters fall into two main groups, the first dealing with the evidence for rural settlement as revealed by archaeological field surveys, and the attendant methodological problems of extrapolating from that evidence to a view of population; and the second with city populations and the phenomenon of urbanization. They proceed to consider hierarchies of settlement in the characteristic classical pattern of city plus territory, the way in which those entities are defined, from the highest to the lowest level: the empire as ‘city of Rome plus territory‘, then regional and local hierarchies, and, more precisely, the identity and the nature of the ‘instruments‘ that enable them to function in economic cohesion.Less

There was always a struggle between science and literature for ownership of the intellectual territory of social criticism and social reform. Balzac's La comedie humaine was the nineteenth century French beginning of literary claim to possession. The struggle never ceased and is now centred on battles over cultural studies as opposed to scientific method. Is schism or reconciliation the solution? Ideally, there is toleration but not necessarily institutional integration.Less

The chapter focuses on quantification as it figures in standard versions of the predicate calculus. These versions are straightforwardly reductive in that non-singular sentences must be re-cast into singular form if they are to receive representation. However, various non-singular sentences, including certain kinds of plural sentences, are refractory to representation in this form. Essentially singular forms of quantifier-expression must be distinguished from non-singular forms to lay the basis for sui generis non-singular forms of quantification, appropriate to both plural nouns and non-count nouns. The maxim ‘to be is to be the value of a variable’ must be rejected.Less

This chapter pursues a strategy for solving the knowability paradox in terms of the general category of the fallacies involved in substituting into intensional contexts. It clarifies and defends the indexical theory of quantification. It argues that the neo-Russellian view of quantification blocks the proofs from knowable truth to known truth (and from unknown truth to unknowable truth), and that the objections raised in the literature to this approach are not damaging.Less

The standing of accounting among the academic disciplines has never been very high, in part because the work of accounting is not regarded as suitably creative. Yet when we think of knowledge as a set of institutionalized practices, the subservience of accounting to the sciences and to the ancient professions may be reversed. Fields like economics, engineering, biology, and medicine cannot escape the twin imperatives of commensuration and accountability, especially when these are brought to bear on matters of recognized public importance. In this regard, the career of cost-benefit quantification is exemplary. Knowledge and rationality, whenever they touch on politics and policy, have become closely bound up with a logic of accountancy.Less

This chapter introduces the most important aspects of Bayesian statistical inference and techniques for performing such calculations in practice. It first reviews the basic steps in Bayesian inference in early sections of the chapter, and then illustrates them with several examples in sections that follow. Numerical techniques for solving complex problems are next discussed, and the final section provides a summary of pros and cons for classical and Bayesian method. It argues that most users of Bayesian estimation methods are likely to use a mix of Bayesian and frequentist tools. The reverse is also true—frequentist data analysts, even if they stay formally within the frequentist framework, are often influenced by “Bayesian thinking,” referring to “priors” and “posteriors.” The most advisable position is to know both paradigms well, in order to make informed judgments about which tools to apply in which situations.Less

Having seen the limitations of a reconstruction of Buridan’s semantics in terms of a modified quantification theory, this chapter begins engaging Buridan’s theory in its own terms, starting with a detailed discussion of the semantic properties of terms. The discussion moves from a brief discussion of Buridan’s distinction between immediate and ultimate signification (securing that the semantic properties of mental terms will be “inherited” by written and spoken terms), to Buridan’s theory of reference, namely, supposition, and oblique reference, namely, appellation. The chapter discusses suppositional descents as distinguishing quantifier-scopes, numerical quantification, and appellation in temporal and modal contexts, as well as Buridan’s peculiar theory of appellatio rationis, the theory of oblique reference to concepts in intentional contexts.Less

This chapter investigates what is involved in asking general ontological questions such as: “what exists?” and “how many things are there?” It is argued that well-formed existence and counting questions are “specific” existence questions that specify a certain category or sort of entity enquired about. Purely “generic” existence and counting questions (asking about “anything whatsoever”, where “thing” is not used sortally) are ill-formed unanswerable questions. This gives us reason to think that quantificational claims likewise presuppose certain categories of entity quantified over. It also suggests that many of the questions driving ontological debates are based on pseudo-questions, and does so without subscribing to anti-realism or quantifier variance. The chapter closes by considering whether we can revive a form of universal quantification by way of a “covering” use of “thing” that generalizes over a range of category-specific terms.Less

This chapter highlights the conceptual aspects of a rating system without focusing on mathematical and technical aspects. An overview is provided of the different aspects of risk measurement and modelling: data, modelling techniques, and implementation for use. All aspects of the development and implementation of a new model are discussed. The system life cycle is explained in section 4.2. Section 4.3 provides a high-level overview on credit scoring models. Such models rely on data, for risk measurement, model use, and model development. The data issues are discussed in Section 4.4. Section 4.5 provides a bird's eye view on the model development process of internal rating systems. Implementation aspects are discussed in Section 4.6. Section 4.7 explains that models need to be maintained and updated regularly. Section 4.8 explains the different, but also partially overlapping aspects of model validation, quality control, and backtesting.Less

This chapter focuses on two main issues: the issue of indexicality, and the extension of the notions of logic to indexical languages; and the issue of the notation itself. It begins with a discussion of logical syntax, and then turns from there to possible characterizations of the notion of consequence. It concludes with a discussion of some further semantic phenomena, which underscore the need to take context and language together.Less

Professional geographers use maps to reveal spatial patterns in their data and to seek correlations in those patterns, although they no longer always do so by the time-honoured method of simple visual comparison of distributions on a series of paper maps. Geographical Information Systems (GIS) are founded on maps stored electronically. In most British geography departments, cartography has been distanced from geography. This chapter discusses the use of maps in geography, quantification and spatial science, maps and public policy in Britain, thematic mapping, compilation of atlases and reading of maps.Less

After initial comments on the role of Greek inscriptions as ‘archives’, this chapter reviews the drastic changes that have occurred since Finley's book of 1973 in the picture of the ancient economy, both by acknowledging development and growth, and by adopting new concepts, not least New Institutional Economics with its emphasis on transaction costs. The methodological impact of such new approaches is sketched in four fields, each of which is illustrated with epigraphic documentation: (1) production and growth, instancing technological advance, land exploitation and textile production; (2) finance, taxes, trade and prices, with emphasis on the need and opportunities for quantification; (3) money and coinage; and (4) the transformation of uncertainty into an assessment of risk, illustrated in respect of farming practices and recourse to consultation of oracles and curse-tablets.Less

Grounding is the grammaticized means of relating the thing profiled by a nominal, or the process profiled by a finite clause, to the ground (the speech event and its participants). As narrowly defined, grounding elements make very fundamental specifications of a basically epistemic nature. Moreover, they construe the ground subjectively—leaving it implicit as the offstage locus of conception—with the profiled entity being the focused, onstage object of conception. Whereas a lexical noun or verb merely names a type of thing or process, a full nominal or finite clause designates and grounds an instance of the type. An instance differs from a type by being thought of as having a particular location in the domain of instantiation, one that distinguishes it from other instances. The profiled instance is not necessarily an actual individual, but may also be a virtual (or fictive) entity confined to a special mental space. A nominal referent is generally identified through a combination of description, which selects a set of eligible candidates, and grounding, which directs attention to a member of this set. Two basic grounding strategies are deixis (abstract pointing) and quantification. The deictic grounding elements—demonstratives and the definite article—are definite: they single out the intended referent independently of the content of the clause containing the nominal. By contrast, with indefinite grounding elements the referent is initially virtual, pending its identification by means of the clausal content (in the case of indefinite articles), or is necessarily virtual (in the case of quantifiers). Clausal grounding is less concerned with identification than with existence, i.e. whether or not an event occurs. For English the basic grounding elements are tense and the modals. The tense opposition present vs. past is a special case of the more schematic value of immediate vs. non-immediate (with respect to the ground). The absence of a modal indicates that the speaker accepts the profiled occurrence as part of the speaker's conception of reality. The presence of a modal indicates that it does not yet have this status, but is still a target for realization. The choice of modal registers the impetus for speaker control, which occurs on either of two levels: effective vs. epistemic control (corresponding to root vs. epistemic modals).Less

This chapter discusses the most important intensional notion: implication. Primarily, what is required is a philosophically adequate formal semantics for ‘if’ in at least one of its many senses. The Curry paradoxes, entailment, non-contraposible implications, relevant logic, and quantification and identity are discussed.Less
