In this superb introduction, Samuel Freeman introduces and assesses the main topics of Rawls' philosophy. Starting with a brief biography and charting the influences on Rawls' early thinking, he goes on to discuss the heart of Rawls's philosophy: his principles of justice and their practical application to society. Subsequent chapters discuss Rawls's theories of liberty, political and economic justice, democratic institutions, goodness as rationality, moral psychology, political liberalism, and international justice and a concluding chapter considers Rawls' legacy. Clearly setting out (...) the ideas in Rawls' masterwork, _A Theory of Justice_, Samuel Freeman also considers Rawls' other key works, including _Political Liberalism_ and _The Law of Peoples_. An invaluable introduction to this deeply influential philosopher, _Rawls_ is essential reading for anyone coming to his work for the first time. (shrink)

The four authors present their speculations about the future developments of mathematical logic in the twenty-first century. The areas of recursion theory, proof theory and logic for computer science, model theory, and set theory are discussed independently.

In this chapter we explain what experimental philosophy of science is, how it relates to the philosophy of science, and STS more broadly, and what sorts of contributions is can make to ongoing research in the philosophy of science.

Samuel Freeman was a student of the influential philosopher John Rawls, he has edited numerous books dedicated to Rawls' work and is arguably Rawls' foremost interpreter. This volume collects new and previously published articles by Freeman on Rawls. Among other things, Freeman places Rawls within historical context in the social contract tradition, and thoughtfully addresses criticisms of this position. Not only is Freeman a leading authority on Rawls, but he is an excellent thinker in his own right, and these articles (...) will be useful to a wide range of scholars interested in Rawls and the expanse of his influence.

Liberalism and Distributive Justice discusses liberalism, capitalism, distributive justice, and John Rawls's difference principle. Chapters are organized in a narrative arc: from liberalism as the dominant political and economic system, to the laws governing interpersonal transactions in liberal society, to basic economic and political institutions that determine distributive justice.

During the last 25 years, researchers studying human reasoning and judgment in what has become known as the “heuristics and biases” tradition have produced an impressive body of experimental work which many have seen as having “bleak implications” for the rationality of ordinary people (Nisbett and Borgida 1975). According to one proponent of this view, when we reason about probability we fall victim to “inevitable illusions” (Piattelli-Palmarini 1994). Other proponents maintain that the human mind is prone to “systematic deviations from (...) rationality” (Bazerman & Neale 1986) and is “not built to work by the rules of probability” (Gould 1992). It has even been suggested that human beings are “a species that is uniformly probability-blind” (Piattelli-Palmarini 1994). This provocative and pessimistic interpretation of the experimental findings has been challenged from many different directions over the years. One of the most recent and energetic of these challenges has come from the newly emerging field of evolutionary psychology, where it has been argued that it’s singularly implausible to claim that our species would have evolved with no “instinct for probability” and, hence, be “blind to chance” (Pinker 1997, 351). Though evolutionary psychologists concede that it is possible to design experiments that “trick our probability.. (shrink)

Public health and service delivery programmes, interventions and policies are typically developed and implemented for the primary purpose of effecting change rather than generating knowledge. Nonetheless, evaluations of these programmes may produce valuable learning that helps determine effectiveness and costs as well as informing design and implementation of future programmes. Such studies might be termed ‘opportunistic evaluations’, since they are responsive to emergent opportunities rather than being studies of interventions that are initiated or designed by researchers. However, current ethical guidance (...) and registration procedures make little allowance for scenarios where researchers have played no role in the development or implementation of a programme, but nevertheless plan to conduct a prospective evaluation. We explore the limitations of the guidance and procedures with respect to opportunistic evaluations, providing a number of examples. We propose that one key missing distinction in current guidance is moral responsibility: researchers can only be held accountable for those aspects of a study over which they have control. We argue that requiring researchers to justify an intervention, programme or policy that would occur regardless of their involvement prevents or hinders research in the public interest without providing any further protections to research participants. We recommend that trial consent and ethics procedures allow for a clear separation of responsibilities for the intervention and the evaluation. (shrink)

Over the past few decades, reasoning and rationality have been the focus of enormous interdisciplinary attention, attracting interest from philosophers, psychologists, economists, statisticians and anthropologists, among others. The widespread interest in the topic reflects the central status of reasoning in human affairs. But it also suggests that there are many different though related projects and tasks which need to be addressed if we are to attain a comprehensive understanding of reasoning.

In recent years evolutionary psychologists have developed and defended the Massive Modularity Hypothesis, which maintains that our cognitive architecture—including the part that subserves ‘central processing’ —is largely or perhaps even entirely composed of innate, domain-specific computational mechanisms or ‘modules’. In this paper I argue for two claims. First, I show that the two main arguments that evolutionary psychologists have offered for this general architectural thesis fail to provide us with any reason to prefer it to a competing picture of the (...) mind which I call the Library Model of Cognition. Second, I argue that this alternative model is compatible with the central theoretical and methodological commitments of evolutionary psychology. Thus I argue that, at present, the endorsement of the Massive Modularity Hypothesis by evolutionary psychologists is both unwarranted and unmotivated. (shrink)

In this paper, we outline and critically evaluate Thomas Hofweber’s solution to a semantic puzzle he calls Frege’s Other Puzzle. After sketching the Puzzle and two traditional responses to it—the Substantival Strategy and the Adjectival Strategy—we outline Hofweber’s proposed version of Adjectivalism. We argue that two key components—the syntactic and semantic components—of Hofweber’s analysis both suffer from serious empirical difficulties. Ultimately, this suggests that an altogether different solution to Frege’s Other Puzzle is required.

This Element, written for researchers and students in philosophy and the behavioral sciences, reviews and critically assesses extant work on number concepts in developmental psychology and cognitive science. It has four main aims. First, it characterizes the core commitments of mainstream number cognition research, including the commitment to representationalism, the hypothesis that there exist certain number-specific cognitive systems, and the key milestones in the development of number cognition. Second, it provides a taxonomy of influential views within mainstream number cognition research, (...) along with the central challenges these views face. Third, it identifies and critically assesses a series of core philosophical assumptions often adopted by number cognition researchers. Finally, the Element articulates and defends a novel version of pluralism about number concepts. (shrink)

Though nativist hypotheses have played a pivotal role in the development of cognitive science, it remains exceedingly obscure how they—and the debates in which they figure—ought to be understood. The central aim of this paper is to provide an account which addresses this concern and in so doing: a) makes sense of the roles that nativist theorizing plays in cognitive science and, moreover, b), explains why it really matters to the contemporary study of cognition. I conclude by outlining a range (...) of further implications of this account for current debate in cognitive science. (shrink)

What are the elements from which the human mind is composed? What structures make up our _cognitive architecture?_ One of the most recent and intriguing answers to this question comes from the newly emerging interdisciplinary field of evolutionary psychology. Evolutionary psychologists defend a _massively modular_ conception of mental architecture which views the mind –including those parts responsible for such ‘central processes’ as belief revision and reasoning— as composed largely or perhaps even entirely of innate, special-purpose computational mechanisms or ‘modules’ that (...) have been shaped by natural selection to handle the sorts of recurrent information processing problems that confronted our hunter-gatherer forebears (Cosmides and Tooby,192; Sperber, 1994; Samuels, 1998a).

Samuels and Stich explore the debate over the extent to which ordinary human reasoning and decision making is rational. One prominent cluster of views, often associated with the heuristics and biases tradition in psychology, maintains that human reasoning is, in important respects, normatively problematic or irrational. Samuels and Stich start by sketching some key experimental findings from this tradition and describe a range of pessimistic claims about the rationality of ordinary people that these and related findings are sometimes (...) taken to support. Such pessimistic interpretations of the experimental findings have not gone unchallenged however: Samuels and Stich outline some of the research on reasoning that has been done by evolutionary psychologists and sketch a cluster of more optimistic theses about ordinary reasoning that such psychologists defend. Although Samuels and Stich think that the most dire pronouncements made by writers in the heuristics and biases tradition are unwarranted, they also maintain that the situation is rather more pessimistic than sometimes suggested by evolutionary psychologists. They conclude by defending this “middle way” and sketch a family of “dual processing” theories of reasoning which, they argue, offer some support for the moderate interpretation they advocate.

Among the most pervasive and fundamental assumptions in cognitive science is that the human mind (or mind-brain) is a mechanism of some sort: a physical device com- posed of functionally specifiable subsystems. On this view, functional decomposition – the analysis of the overall system into functionally specifiable parts – becomes a central project for a science of the mind, and the resulting theories of cognitive archi- tecture essential to our understanding of human psychology.

Machery argues that concepts do not constitute a natural kind. We argue that this is a mistake. When appropriately construed, his discussion in fact bolsters the claim that concepts are a natural kind.

Spirituality is a universal human experience. Within the process of development, the role of spirituality as a developmental asset is understudied in general and especially within majority world contexts. In this article, we frame advances in spirituality research and practice with youth around three pillars: (a) theory, (b) measurement, and (c) research about and evaluations of positive youth development (PYD) programs in low- and middle-income countries. We place PYD programs as associated with dynamic, relational developmental systems (RDS)-based models of human (...) development, describe spirituality and the “Big Three” features of effective PYD programs as aligning to promote thriving, and discuss spirituality as a strength, as a key asset, in the lives of youth. We discuss advances in developmental methods and measures for describing, explaining, and promoting spirituality and PYD and offer a case study that responds to a United States Agency for International Development call for action and evaluations of spirituality within the context of a PYD program in the majority world. Considerations for future research about spirituality and youth development are discussed. (shrink)

In this paper I defend the classical computational account of reasoning against a range of highly influential objections, sometimes called relevance problems. Such problems are closely associated with the frame problem in artificial intelligence and, to a first approximation, concern the issue of how humans are able to determine which of a range of representations are relevant to the performance of a given cognitive task. Though many critics maintain that the nature and existence of such problems provide grounds for rejecting (...) classical computationalism, I show that this is not so. Some of these putative problems are a cause for concern only on highly implausible assumptions about the extent of our cognitive capacities, whilst others are a cause for concern only on similarly implausible views about the commitments of classical computationalism. Finally, some versions of the relevance problem are not really objections but hard research issues that any satisfactory account of cognition needs to address. I conclude by considering the diagnostic issue of why accounts of cognition in general—and classical computational accounts, in particular—have faired so poorly in addressing such research issues.Keywords: Computationalism; Frame problem; Relevance.

There are multiple formal characterizations of the natural numbers available. Despite being inter-derivable, they plausibly codify different possible applications of the naturals – doing basic arithmetic, counting, and ordering – as well as different philosophical conceptions of those numbers: structuralist, cardinal, and ordinal. Nevertheless, some influential philosophers of mathematics have argued for a non-egalitarian attitude according to which one of those characterizations is more “legitmate” in virtue of being “more basic” or “more fundamental”. This paper addresses two related issues. First, (...) we review some of these non-egalitarian arguments, lay out a laundry list of different, legitimate, notions of relative priority, and suggest that these arguments plausibly employ different such notions. Secondly, we argue that given a metaphysical-cum-epistemological gloss suggested by Frege’s foundationalist epistomology, the ordinals are plausibly more basic than the cardinals. This is just one orientation to relative priority one could take, however. Ultimately, we subscribe to an egalitarian attitude towards these formal characterizations: they are, in some sense, equally “legitimate”. (shrink)

A mime presented on videotape Adler’s six great ideas of truth, goodness, beauty, liberty, equality, and justice; their opposites; and the transitions from the positive or “good” concepts to their opposites. Using Johansson’s (1973) technique, the performer’s 12 joints were marked with points of light. Overall, the viewers had marginal success in identifying the concepts, but females were much more successful than males in identifying the “bad” ones of evil, slavery, falsehood, and ugliness, averaging 62% correct to the males’ 23%.

In a recent issue of Journal of Medical Ethics, we discussed the ethical review of evaluations of interventions that would occur whether or not the evaluation was taking place. We concluded that standard research ethics frameworks including the Ottawa Statement, which requires justification for all aspects of an intervention and its roll-out, were a poor guide in this area. We proposed that a consideration of researcher responsibility, based on the consequences of the research taking place, would be a more appropriate (...) way delineate the scope of research ethics review. Weijer and Taljaard present a counterargument to our proposal, which we address in this reply. They claim that a focus on researcher responsibility will weaken the protection of research participants and link it to ‘unethical research’ and a ‘government experimenting on its own people’. However, the moral responsibility of researchers is defined in terms of the consequences of the research on human welfare and harm, not in opposition to it. Weijer and Taljaard argue that researchers must justify what they are studying whether or not they have any control over it and that governments must justify their programmes, including by demonstrating equipoise, to a research ethics committee if they implement them in a randomised way. We strongly disagree that this is a defensible way to define the scope of research ethics review and argue that this provides no further protections to research participants beyond what we propose, but places a potential barrier to learning from government programmes.

Times of heightened risk to the physical safety of their citizens inevitably cause democracies to recalibrate their institutions and processes and to reinterpret existing legal norms, with greater emphasis on security, and less on individual liberty, than in "normal" times. This article explores the ways in which the American courts have responded to the tension between civil liberties and national security in times of crises. This history illustrates that courts have rejected both of the two polar positions that characterize public (...) discourse on these issues. Civil libertarians argue that political bodies are too easily gripped by passions, hysteria, and self-interest in these times and that courts therefore ought to play a central role in protecting liberty. Executive unilateralists argue that the qualities that uniquely characterize the executive branch, such as decisiveness, access to information, and efficiency, must become so dominant in these moments that few checks, if any, should constrain executive prerogatives. Oddly, civil libertarians and executive unilateralists find implicit consensus in the view that, in times of war, courts have tended not to play a significant role in overseeing executive power. We argue to the contrary: historically, a significant constitutional tradition of judicial scrutiny in the United States during times of war does exist. But this scrutiny does not take the form of courts making first-order substantive judgments about the content of liberty or other claimed constitutional rights. Nor does it take the form of judicial assessment of how significant or credible the national security claims of the executive branch might be. Instead, judicial oversight has been focused on preserving the institutional structures and processes through which decisionmaking on these issues takes place. The judicial role has centered on the second-order question of whether the right institutional processes have been used to make the decisions at issue, rather than on what the content of the underlying rights ought to be. This approach has historically rejected or resisted most claims of executive unilateralism. When courts have upheld the government's actions, they have done so only after a judgment that Congress, as well as the executive, has endorsed the action. This approach has also rejected the civil libertarian framework. When courts find bilateral institutional endorsement, they have typically accepted the joint political judgment of how liberty and security tradeoffs ought to be made. By focusing on congressional endorsement of emergency measures, the courts have created a broad-based political accountability for the actions taken in the name of national security. We suggest that even if congressional endorsement is more apparent than real in some of these contexts, the judicial maintenance of this structure of rhetorical justifications sustains desirable understandings of political structure. Because the President and Congress draw from different political constituencies in a presidential rather than a parliamentary system, we also raise questions about whether the American judicial approach to these questions should be limited to political systems with separated executive and legislative powers.

There is a puzzling tension in contemporary scientific attitudes towards human nature. On the one hand, evolutionary biologists correctly maintain that the traditional essentialist conception of human nature is untenable; and moreover that this is obviously so in the light of quite general and exceedingly well-known evolutionary considerations. On the other hand, talk of human nature abounds in certain regions of the sciences, especially in linguistics, psychology and cognitive science. In this paper I articulate a conception of human nature that (...) a) captures how cognitive and behavioral scientists tend to deploy the notion whilst, b) evading standard evol-utionary objections, and c) allowing human nature – and theories thereof – to fulfill many of their traditional theoretical roles.

There is a venerable philosophical tradition that views human beings as intrinsically rational, though even the most ardent defender of this view would admit that under certain circumstances people’s decisions and thought processes can be very irrational indeed. When people are extremely tired, or drunk, or in the grip of rage, they sometimes reason and act in ways that no account of rationality would condone. About thirty years ago, Amos Tversky, Daniel Kahneman and a number of other psychologists began reporting (...) findings suggesting much deeper problems with the traditional idea that human beings are intrinsically rational animals. What these studies demonstrated is that even under quite ordinary circumstances where fatigue, drugs and strong emotions are not factors, people reason and make judgments in ways that systematically violate familiar canons of rationality on a wide array of problems. Those first surprising studies sparked the growth of a major research tradition whose impact has been felt in economics, political theory, medicine and other areas far removed from cognitive science. In Section 2, we will sketch a few of the better known experimental findings in this area. We’ve chosen these particular findings because they will play a role at a later stage of the paper. For readers who would like a deeper and more systematic account of the fascinating and disquieting research on reasoning and judgment, there are now several excellent texts and anthologies available.

According to the Rationality Constraint, our concept of belief imposes limits on how much irrationality is compatible with having beliefs at all. We argue that empirical evidence of human irrationality from the psychology of reasoning and the psychopathology of delusion undermines only the most demanding versions of the Rationality Constraint, which require perfect rationality as a condition for having beliefs. The empirical evidence poses no threat to more relaxed versions of the Rationality Constraint, which only require only minimal rationality. Nevertheless, (...) we raise problems for all versions of the Rationality Constraint by appealing to more extreme forms of irrationality that are continuous with actual cases of human irrationality. In particular, we argue that there are conceivable cases of “mad belief” in which populations of Lewisian madmen have beliefs that are not even minimally rational. This undermines Lewis’s claim that our ordinary concept of belief is a theoretical concept that is implicitly defined by its role in folk psychology. We argue that introspection gives us a phenomenal concept of belief that cannot be analyzed by applying Lewis’s semantics for theoretical terms. (shrink)

In their recent and influential book Rethinking Innateness, Jeffrey Elman and his co‐authors argue that evidence from neurobiology provides us with grounds to reject representational nativism (RN).

Moreover, I briefly discuss how we ought to understand RN and argue that on two prima facie plausible approaches, far (...) from refuting nativism, the evidence from neurobiology may not even be relevant to the question of whether or not RN is true.

The concept of innateness has historically exerted an influence in many regions of biology and it continues to play a significant role in cognitive science especially, developmental psychology and linguistics. This chapter provides an overview of some recent efforts to empirically study the innateness concept, both as deployed in folk contexts and among scientists. It considers whether this research really bolsters the standard criticism. The chapter describes research by Paul Griffiths and his collaborators, which seeks to assess whether the folk (...) concept of innateness is a manifestation of the folk biology. It reviews further research, largely due to Josh Knobe and Richard Samuels, on folk innateness judgments. The chapter describes how this research was extended in order to explore the issue of whether scientists’ innateness judgments rely on a distinctly scientific innateness concept, or whether they merely redeploy the folk concept.

The concept of innateness appears in systematic research within cognitive science, but it also appears in less systematic modes of thought that long predate the scientific study of the mind. The present studies therefore explore the relationship between the properly scientific uses of this concept and its role in ordinary folk understanding. Studies 1-4 examined the judgments of people with no specific training in cognitive science. Results showed (a) that judgments about whether a trait was innate were not affected by (...) whether or not the trait was learned, but (b) such judgments were impacted by moral considerations. Study 5 looked at the judgments of both non-scientists and scientists, in conditions that encouraged either thinking about individual cases or thinking about certain general principles. In the case-based condition, both non-scientists and scientists showed an impact of moral considerations but little impact of learning. In the principled condition, both non-scientists and scientists showed an impact of learning but little impact of moral considerations. These results suggest that both non-scientists and scientists are drawn to a conception of innateness that differs from the one at work in contemporary scientific research but that they are also both capable of 'filtering out' their initial intuitions and using a more scientific approach.

Number words seemingly function both as adjectives attributing cardinality properties to collections, as in Frege’s ‘Jupiter has four moons’, and as names referring to numbers, as in Frege’s ‘The number of Jupiter’s moons is four’. This leads to what Thomas Hofweber calls Frege’s Other Puzzle: How can number words function as modifiers and as singular terms if neither adjectives nor names can serve multiple semantic functions? Whereas most philosophers deny that one of these uses is genuine, we instead argue that (...) number words, like many related expressions, are polymorphic, having multiple uses whose meanings are systematically related via type shifting.

Debating Terrorism is an innovative new textbook, addressing a number of key issues in contemporary terrorism studies from both 'traditional' and 'critical' perspectives. In recent years, the terrorism studies field has grown in quantity and quality, with a growing number of scholars rooted in various professional disciplines beginning to debate the complex dynamics underlying this category of violence. Within the broader field, there are a number of identifiable controversies and questions which divide scholarly opinion and generate opposing arguments. These relate (...) to theoretical issues, such as the definition of terrorism and state terrorism, substantive issues like the threat posed by al Qaeda and the utility of different responses to terrorism, different pathways leading people to engage in terrorist tactics, and ethical issues such as the torture of terrorist suspects and targeted assassination. This volume aims to bring together in one place many of the field's leading scholars to debate the key issues relating a set of 12 important controversies and questions. The format of the volume involves a leading scholar taking a particular position on the controversy, followed by an opposing or alternative viewpoint written by another scholar. In addition to the pedagogic value of allowing students to read opposing arguments in one place, the volume will also be important for providing an overview of the state of the field and its key lines of debate. This textbook will be essential reading for all students of terrorism and political violence, critical terrorism studies, critical security studies, security studies and IR in general. (shrink)

This chapter offers a high-level overview of the philosophy of cognitive science and an introduction to the Oxford Handbook of Philosophy of Cognitive Science. The philosophy of cognitive science emerged out of a set of common and overlapping interests among philosophers and scientists who study the mind. We identify five categories of issues that illustrate the best work in this broad field: (1) traditional philosophical issues about the mind that have been invigorated by research in cognitive science, (2) issues regarding (...) the practice of cognitive science and its foundational assumptions, (3) issues regarding the explication and clarification of core concepts in cognitive science, (4) first-order empirical issues where philosophers participate in the interdisciplinary investigation of particular psychological phenomena, (5) traditional philosophical issues that aren’t about the mind but that can be informed by a better understanding of how the mind works.

Plagiarism is often equated with theft, but closer inspection reveals plagiarism’s distinctive dimensions. Fundamentally, plagiarism is a form of deception, whereby the plagiarist uses the instructor as a means toward the plagiarist’s own end. Implicitly asking the instructor for a fair and accurate evaluation of the student’s abilities, the plagiarist at the same time sabotages the instructor’s capacity to make that judgment, thereby violating a duty inherent in the student-teacher relationship. Moreover, every act of plagiarism damages the plagiarist’s integrity, thereby (...) subverting his/her own well-being, while contributing as well to a widespread devaluing of education for both the individual and society.

The philosophy of cognitive science is concerned with fundamental philosophical and theoretical questions connected to the sciences of the mind. How does the brain give rise to conscious experience? Does speaking a language change how we think? Is a genuinely intelligent computer possible? What features of the mind are innate?

Emotion development research centrally concerns capacities to produce emotions and to think about them. We distinguish these enterprises and consider a novel account of how they might be related. On one recent account, the capacity to have emotions of various kinds comes by way of the acquisition of emotion concepts. This account relies on a constructionist theory of emotions and an embodied theory of emotion concepts. We explicate these elements, then raise a challenge for the approach. It appears to be (...) incompatible with various familiar ways in which cognitions about one’s own emotions can come apart from episodes of emotion. (shrink)
