Contemporary Philosophy in Focus will offer a series of introductory volumes to many of the dominant philosophical thinkers of the current age. Each volume will consist of newly commissioned essays that will cover all the major contributions of a preeminent philosopher in a systematic and accessible manner. Author of such groundbreaking and influential books as Consciousness Explained and Darwin's Dangerous Idea, Daniel C. Dennett has reached a huge general and professional audience that extends way beyond the confines of academic philosophy. He has made significant contributions to the study of consciousness, the development of the child's mind, cognitive ethnology, explanation in the social sciences, artificial intelligence, and evolutionary theory. This volume is the only truly introductory collection that traces these connections, explores the implications of Dennett's work, and furnishes the non-specialist with a fully-rounded account of why Dennett is such an important voice on the philosophical scene.

Ladyman and Ross argue that analytic metaphysics is a misguided enterprise that should give way to a naturalized metaphysics that aims to reconcile everyday and special-scientific ontologies with fundamental physics as the authoritative source of knowledge on the general structure of the universe. Le Bihan and Barton (argue, as against this, that analytic metaphysics remains useful as a basis for the body of work in AI known as “applied ontology.” They stop short of claiming, however, that analytic metaphysics is useful as metaphysics. I consider a basis for making the stronger claim: Smith's project for building what he claims to be metaphysical foundations for applied ontology (and for AI generally). Ultimately, the stronger claim is rejected; but in the course of this dialectic new aspects of the naturalistic metaphysical project come to light, including relationships between it and the traditional metaphysical project of providing foundations for philosophical semantics of truth and reference.

This insightful Modern Guide offers a broad coverage of questions and controversies encountered by contemporary economists. A refreshing approach to philosophy of economics, chapters comprise a range of methodological and theoretical perspectives, from lab and field experiments to macroeconomics and applied policy work, written using a familiar, accessible language for economists. Highlighting key areas of methodological controversy, the Modern Guide looks at estimating utility functions in choice data, causal modelling, and ethics in randomised control trials. Chapters further explore topical issues, including: economists' attitudes to other disciplines; gender bias in economic research; methods of modelling social influence in economics; behavioural welfare economics; anti-poverty policy controversies; and inflexible reliance on DSGE models in macroeconomics. Furthermore, it explores the implications of the last financial crisis for macroeconomic confidence, and ways to adapt abstract theory to everyday policy advice. Avoiding philosophical jargon, and with the majority of chapters written by economists, this Modern Guide will challenge economists and scholars of philosophy of economics to engage with different approaches to the topic. This will also be a useful tool for policy makers administering nudges, development initiatives, macro-forecasting and monetary policy."--Publisher's description.

The Oxford Handbook of Philosophy of Economics is a reference work on philosophical issues in the practice of economics. It is motivated by the view that there is more to economics than general equilibrium theory, and that the philosophy of economics should reflect the diversity of activities and topics that currently occupy economists. Contributions in the book are thus closely tied to on-going theoretical and empirical concerns in economics. Contributors include both philosophers of science and economists. Articles fall into three general categories: received views in philosophy of economics, on-going controversies in microeconomics, and issues in modeling, macroeconomics, and development. Specific topics include methodology, game theory, experimental economics, behavioral economics, neuroeconomics, computational economics, data mining, interpersonal comparisons of utility, measurement of welfare and well-being, growth theory and development, and microfoundations of macroeconomics.

Does the desirability of social institutions for public goods provision depend on the extent to which they include mechanisms for endogenous enforcement of cooperative behavior? We consider alternative institutions that vary the use of direct punishments to promote social cooperation. In one institution, subjects participate in a public goods experiment in which an initial stage of voluntary contribution is followed by a second stage of voluntary, costly sanctioning. Another institution consists of the voluntary contribution stage only, with no subsequent opportunity to sanction. In a third stage subjects vote for which institution they prefer for future interactions: do they prefer one that does allow sanctions or one that does not allow sanctions? Our results show that even though sanctions are frequently used when available, the clear majority of individuals vote for the institution that does not allow sanctions. Thus, a distinction is required between the principles that guide the choice of institutions and the principles that apply to actions guided by institutions. Our results indicate that it is the wealth generated by the institution that determines its desirability.

This book argues that the only kind of metaphysics that can contribute to objective knowledge is one based specifically on contemporary science as it really is, and not on philosophers' a priori intuitions, common sense, or simplifications of science. In addition to showing how recent metaphysics has drifted away from connection with all other serious scholarly inquiry as a result of not heeding this restriction, this book demonstrates how to build a metaphysics compatible with current fundamental physics, which, when combined with metaphysics of the special sciences, can be used to unify physics with the other sciences without reducing these sciences to physics itself. Taking science metaphysically seriously, this book argues, means that metaphysicians must abandon the picture of the world as composed of self-subsistent individual objects, and the paradigm of causation as the collision of such objects. The text assesses the role of information theory and complex systems theory in attempts to explain the relationship between the special sciences and physics, treading a middle road between the grand synthesis of thermodynamics and information, and eliminativism about information. The consequences of the books' metaphysical theory for central issues in the philosophy of science are explored, including the implications for the realism versus empiricism debate, the role of causation in scientific explanations, the nature of causation and laws, the status of abstract and virtual objects, and the objective reality of natural kinds.

A principal source of interest in behavioral economics has been its advertised contributions to policies aimed at ‘nudging’ people away from allegedly natural but self-defeating behavior toward patterns of response thought more likely to improve their welfare. This has occasioned controversies among economists and philosophers around the normative limits of paternalism, especially by technical policy advisors. One recent suggestion has been that ‘boosting,’ in which interventions aim to enhance people’s general cognitive skills and representational repertoires instead of manipulating their choice environments behind their backs, avoids the main normative challenges. A limitation in most of this literature is that it has focused on relatively sweeping policy recommendations and consequently on strong polar alternatives of general paternalism and strict laissez faire. We review a real instance, drawn from a consulting project we conducted for an investment bank, of a proposed intervention that is more typical of the kind that economists are more often actually called upon to offer. In this example, the sophistication of current tools for preference attribution, combined with philosophical externalism about the semantics of preferences that makes it less plausible to attribute their literal self-conscious representation to people as propositional attitude content becomes more tightly refined, blocks applicability of the distinction between nudging and boosting. This seems to call for irreducible, context-specific ethical judgment in assessing the appropriateness of the forms of paternalism that economists must actually wrestle with in going about their everyday business.

The Internet and social media have opened niches for political exploitation of human dispositions to hyper-alarmed states that amplify perceived threats relative to their objective probabilities of occurrence. Researchers should aim to observe the dynamic “ramping up” of security threat mechanisms under controlled experimental conditions. Such research necessarily begins from a clear model of standard baseline states, and should involve adding treatments to established experimental protocols developed by experimental economists. We review these protocols, which allow for joint estimation of risk preferences and subjective beliefs about probabilities and their distributions. Results we have obtained on such estimates, from populations in various countries, are gathered for comparison. Most people show moderate risk aversion in non-alarmed states. We also find universal heterogeneity in risk preference structures, with substantial sub-samples weighting probabilities in such a way as to display “probability pessimism”, while others make risky choices in accordance with expected utility theory.

Much behavioral welfare economics assumes that expected utility theory does not accurately describe most human choice under risk. A substantial literature instead evaluates welfare consequences by taking cumulative prospect theory as the natural default alternative, at least where description is concerned. We present evidence, based on a review of previous literature and new experimental data, that the most empirically adequate hypothesis about human choice under risk is that it is heterogeneous, and that where EUT does not apply, more choice is characterized by rank-dependent utility models than by CPT. Most of the apparently loss-averse choice behavior results from probability weighting rather than from direct disutility experienced when an outcome is framed as a loss against an idiosyncratic reference point. We then consider implications of this finding for methodological debates about how to model welfare effects of policies, and argue that abandonment of a dogmatic belief in CPT as the correct theory of risk human choice exposes a conceptual error that is widespread in behavioral welfare economics. We provide concluding reflections on second-order, philosophical issues around the grounding of normative commitments in policy-focused economics.

As regimes move from illiberal to liberal, post-transition justice methodology has been employed to engender truth and reconciliation. These normative concepts have evolved into a policy of creating truth and reconciliation commissions that trade civil and criminal amnesty with applicants in exchange for information. This bargained-for exchange can be analyzed as an imperfect information game, where the commission attempts to maximize information while the applicant seeks amnesty for the lowest possible price. Using game-theoretic analysis, the authors model the truth-amnesty game and predict the optimal commission strategy. The analysis leads to the recommendation that future transitional justice commissions employ various specific lexicographic ordering strategies to minimize dead weight loss in the transaction.

This book explores and offers solutions to a range of conceptual and philosophical problems that underlie attempts to understand metaphor processing in the context of cognitive science. The author vigorously criticizes the prevailing philosophical prejudice against traditional «comparison» theories of metaphor, arguing that the problems with the comparison theory are exciting problems that demand solutions, rather than grounds for rejecting the theory itself. Furthermore, it is through these problems that the study of metaphor processing is linked to wider issues in cognitive science, including disputes about computational architectures and neural mechanisms.

In this study, Don Ross explores the relationship of economics to other branches of behavioral science, asking, in the course of his analysis, under what interpretation economics is a sound empirical science. The book explores the relationships between economic theory and the theoretical foundations of related disciplines that are relevant to the day-to-day work of economics -- the cognitive and behavioral sciences. It asks whether the increasingly sophisticated techniques of microeconomic analysis have revealed any deep empirical regularities -- whether technical improvement represents improvement in any other sense. Casting Daniel Dennett and Kenneth Binmore as its intellectual heroes, the book proposes a comprehensive model of economic theory that, Ross argues, does not supplant, but recovers the core neoclassical insights, and counters the caricaturish conception of neoclassicism so derided by advocates of behavioral or evolutionary economics. Because he approaches his topic from the viewpoint of the philosophy of science, Ross devotes one chapter to the philosophical theory and terminology on which his argument depends and another to related philosophical issues. Two chapters provide the theoretical background in economics, one covering developments in neoclassical microeconomics and the other treating behavioral and experimental economics and evolutionary game theory. The three chapters at the heart of the argument then apply theses from the philosophy of cognitive science to foundational problems for economic theory. In these chapters, economists will find a genuinely new way of thinking about the implications of cognitive science for economics, and cognitive scientists will find in economic behavior, a new testing site for the explanations of cognitive science

The chapter compares a leading psychological account of procrastination and related phenomena—the picoeconomic framework of George Ainslie—with economic models of self-control lapses generally and procrastination specifically. By “economic,” reference is intended to models that admit of solution by maximizing utility functions and that can be tested econometrically against behavioral or neural processing data. The chapter demonstrates how bargaining games among picoeconomic interests (as Ainslie depicts them) can take two forms. One of these forms corresponds to dual-self models of self-control that have unique Markov Perfect Nash Equilibria as solutions. The other form has yet to be modeled, but promising tools for the job are in place.

People differ in the extent to which they discount the values of future rewards. Behavioural economists measure these differences in terms of functions that describe rates of reduced valuation in the future – temporal discounting – as these vary with time. They measure differences in preference for risk – differing rates of probability discounting – in terms of similar functions that describe reduced valuation of rewards as the probability of their delivery falls. So-called ‘impulsive’ people, including people disposed to addiction, tend to choose rewards in patterns that are described by unusually steeply sloped discount functions. The empirical literature is ambivalent as to whether this applies to pathological gamblers (PGs) who manifest most other behavioural patterns associated with addiction, with different, equally careful studies suggesting opposite conclusions (Petry & Casarella 1999; Holt, Green & Myerson 2003). This puzzle may arise from the fact that most previous experiments on discounting behaviour were not designed so as to allow effects of high temporal discounting to be distinguished from effects of low probability discounting. (Addiction has sometimes been associated with the latter because it seems to involve, at least in the starting addict, under appreciation of risk.) Our research project investigates both forms of discounting behaviour and their relationship to severity of risk of PG in a community sample of South African gamblers.

This chapter discusses the plausibility of the criticism against the thesis that external factors causally influence cognition and that they are, consequently, partly constitutive of cognition. The discussion should not be taken as implicitly proposing that the opposite theory is true, although the works of Adams and Aizawa suggest that they are defending internalism. This can be attributed to the fact that systems are, by definition, bounded; one must make assumptions about systems in developing cognitive models. This chapter defends the position that metaphysical considerations should play no role in deciding how to model cognition. It further explains how there is no basis for a general fact of the matter about determining what is and what is not a cognitive system.

This chapter argues that a form of structural realism is motivated by reflection on issues that arise in two different domains that have been the subject of intense scrutiny during recent decades. These domains are related to: firstly, problems from the history of science about the abandonment of ontological commitments as old theories which are replaced by more empirically adequate ones; and secondly, questions arising from the debate between scientific realists and constructive empiricists about what really is at stake between them, and about the inadequacies of constructive empiricism. The so-called “semantic” or “model-theoretic” understanding of the nature of scientific representation is suggested to fit very well with the kind of structural realism advocated in this chapter. The structure of the argument presented here is dialectical. The most serious problems for constructive empiricism are explained, and van Fraassen's empiricism is supplemented with a commitment to objective modality to respond to such problems.
