Tversky and Kahneman (1974) originally discussed three main heuristics: availability, representativeness, and anchoring-and-adjustment. Research on judgemental forecasting suggests that the type of information on which forecasts are based is the primary factor determining the type of heuristic that people use to make their predictions. Specifically, availability is used when forecasts are based on information held in memory; representativeness is important when the value of one variable is forecast from explicit information about the value of another variable; and anchoring-and-adjustment is employed (...) when the value of a variable is forecast from explicit information about previous values of that same variable. Although there has been increased emphasis on the adaptiveness of heuristics and increased interest in specifying their use in terms of computational models, this way of structuring our knowledge about judgemental forecasting continues to be a useful one. I use it to frame discussion of some recent debates in the area. (shrink)

I make three points. First, processors and depletable resources should not be regarded as alternative means of processing information: they are both necessary. Second, comparing a processor account with a rational allocation mechanism to a depletable-resources account without one is not a fair comparison. Third, depletable resources can act as signals as well as fuels.

People made forecasts from graphically presented time series. Series were sinusoids overlaid by a zero or positive linear trend and a zero, low, moderate, or high level of noise. Forecasting performance was affected by both these variables. However, it did not correlate with ability to identify the trend and correlated significantly with ability to detect the sinusoidal pattern only when series were noise-free. A second experiment showed that the effect of data noise was not influenced by the number of forecasts (...) that people made from a series. These findings are consistent with the view that data noise does not affect the way that forecasts are made but that it impairs them for two reasons. First, it renders the anchor-and-adjust heuristics underlying them less effective. Second, it causes people to add more noise to their judgements in their attempts to make them representative of the data. (shrink)

The previous papers raise a number of issues. How should we develop task typologies both to separate judgement from related cognitive tasks and to classify tasks within the judgement domain? Are there grounds for selecting between models of judgement when empirical tests fail to do so? What techniques can be used to find out more about the cognitive processes underlying judgement behaviour? I discuss these issues and give a brief assessment of the current state of play in this rapidly changing (...) area. (shrink)

This is a critical survey of writing on the philosophy of photography.

If an artist sends a live peacock to an exhibition, is it art? 'What is art?' is a question many of us want answered but are too afraid to ask. It is the very question that Nigel Warburton demystifies in this brilliant and accessible little book. With the help of varied illustrations and photographs, from Cézanne and Francis Bacon to Andy Warhol and Damien Hirst, best-selling author Warburton brings a philosopher's eye to art in a refreshing jargon-free style. With (...) customary clarity, he explains art theories, that are much discussed but little understood, by thinkers such as Clive Bell, R.G Collingwood and Wittgenstein. He illuminates other perplexing problems in art, such as the artist's intention, representation and emotion. Drawing on photographs of Cindy Sherman and Tiananmen Square, Warburton shows that, if we are ever to answer the art question, we must consider each work of art on its own terms. A stimulating and handy guide through the art maze, The Art Question is essential reading for anyone interested in art, philosophy or those who simply like looking at and thinking about pictures.

Unlike topics such as criminal responsibility, dangerousness has only recently begun to interest philosophically minded penologists. The most likely explanation is that until the middle of this century the periods for which people who had done serious harm to others were incarcerated in the UK so long that when they were released their age or condition or circumstances made them unlikely to repeat their crimes. It was only when pressure of resources—in plain terms overcrowded prisons and mental hospitals—forced the shortening (...) of these periods that it became politically necessary to worry about the possible dangerousness of really substantial numbers of prisoners and patients who became eligible for release. The problem was not entirely new. A few lifers, for example, had been set free each year, under licences which lasted for the rest of their lives; and the Special Hospitals which housed the violent insane had discharged carefully selected inmates, also under supervision. But by the late 1960s the introduction of parole, the Mental Health Act and the abolition of capital punishment had greatly increased the number of cases in which the problem of dangerousness had to be faced, and difficult decisions had to be taken.

What is the fruit of a searching dialogue between faith and reason? This book collects theological and philosophical perspectives on the richness of the faith-reason dialogue, including examples from literature, continental and analytic philosophy, worship and liturgy, and radical approaches to issues of racism and prejudice. The authors strongly resist the temptations to either disregard the faith-reason dialogue or take it for granted. Through their explorations and reflections they open up new vistas and horizons on a topic more necessary than (...) ever. (shrink)

Cognitive science has always included multiple methodologies and theoretical commitments. The philosophy of cognitive science should embrace, or at least acknowledge, this diversity. Bechtel’s (2009a) proposed philosophy of cognitive science, however, applies only to representationalist and mechanist cognitive science, ignoring the substantial minority of dynamically oriented cognitive scientists. As an example of nonrepresentational, dynamical cognitive science, we describe strong anticipation as a model for circadian systems (Stepp & Turvey, 2009). We then propose a philosophy of science appropriate to nonrepresentational, dynamical (...) cognitive science. (shrink)

What can computers do in principle? What are their inherent theoretical limitations? These are questions to which computer scientists must address themselves. The theoretical framework which enables such questions to be answered has been developed over the last fifty years from the idea of a computable function: intuitively a function whose values can be calculated in an effective or automatic way. This book is an introduction to computability theory (or recursion theory as it is traditionally known to mathematicians). Dr Cutland (...) begins with a mathematical characterisation of computable functions using a simple idealised computer (a register machine); after some comparison with other characterisations, he develops the mathematical theory, including a full discussion of non-computability and undecidability, and the theory of recursive and recursively enumerable sets. The later chapters provide an introduction to more advanced topics such as Gildel's incompleteness theorem, degrees of unsolvability, the Recursion theorems and the theory of complexity of computation. Computability is thus a branch of mathematics which is of relevance also to computer scientists and philosophers. Mathematics students with no prior knowledge of the subject and computer science students who wish to supplement their practical expertise with some theoretical background will find this book of use and interest.

This paper proposes a model of human uniqueness based on an unusual distinction between two contrasted kinds of political competition and political status: (1) antagonistic competition, in quest of dominance (antagonistic status), a zero-sum, self-limiting game whose stake—who takes what, when, how—summarizes a classical definition of politics (Lasswell 1936), and (2) synergistic competition, in quest of merit (synergistic status), a positive-sum, self-reinforcing game whose stake becomes “who brings what to a team’s common good.” In this view, Rawls’s (1971) famous virtual (...) “veil of ignorance” mainly conceals politics’ antagonistic stakes so as to devise the principles of a just, egalitarian society, yet without providing any means to enforce these ideals (Sen 2009). Instead, this paper proposes that human uniqueness flourished under a real “adapted veil of ignorance” concealing the steady inflation of synergistic politics which resulted from early humans’ sturdy egalitarianism. This proposition divides into four parts: (1) early humans first stumbled on a purely cultural means to enforce a unique kind of within-team antagonistic equality—dyadic balanced deterrence thanks to handheld weapons (Chapais 2008); (2) this cultural innovation is thus closely tied to humans’ darkest side, but it also launched the cumulative evolution of humans’ brightest qualities—egalitarian team synergy and solidarity, together with the associated synergistic intelligence, culture, and communications; (3) runaway synergistic competition for differential merit among antagonistically equal obligate teammates is the single politically selective mechanism behind the cumulative evolution of all these brighter qualities, but numerous factors to be clarified here conceal this mighty evolutionary driver; (4) this veil of ignorance persists today, which explains why humans’ unique prosocial capacities are still not clearly understood by science. The purpose of this paper is to start lifting this now-ill-adapted veil of ignorance, thus uncovering the tight functional relations between egalitarian team solidarity and the evolution of human uniqueness.

Theories of superior collicular and hippocampal function have remarkable similarities. Both structures have been repeatedly implicated in spatial and attentional behaviour and in inhibitory control of locomotion. Moreover, they share certain electrophysiological properties in their single unit responses and in the synchronous appearance and disappearance of slow wave activity. Both are phylogenetically old and the colliculus projects strongly to brainstem nuclei instrumental in the generation of theta rhythm in the hippocampal EECOn the other hand, close inspection of behavioural and electrophysiological (...) data reveals disparities. In particular, hippocampal processing mainly concerns stimulus ambiguity, contextual significance, and spatial relations or other subtle, higher order characteristics. This requires the use of largely preprocessed sensory information and mediation of poststimulus investigation. Although collicular activity must also be integrated with that of “higher” centres, its primary role in attention is more “peripheral” and specific in controlling orienting/localisation via eye and body movements toward egocentrically labelled spatial positions. In addition, the colliculus may exert a nonspecific influence in alerting higher centres to the imminence of information potentially worthy of focal attention. Nevertheless, it is noteworthy that collicular and hippocampal lesions produce deficits on similar tasks, although the type of deficit is usually different in each case. Functional overlap between hippocampus and colliculus is virtually certain vis-à-vis stimulus sampling, for example in the acquisition of information via vibrissal movements and visual scanning. In addition, insofar as stimulus significance is a factor in collicular orienting mechanisms, the hippocampus — cingulate – cortex — colliculus pathway may play a significant role, modulating collicular responsiveness and thus ensuring an attentional strategy appropriate to current requirements. A tentative “reciprocal loop” model is proposed which bridges physiological and behavioural levels of analysis and which would account for the observed degree and nature of functional overlap between the superior colliculus and hippocampus.

This study of the implications of Gillick competence argues it is an unnecessary burden with an unethical foundation. The ethics of adolescent medical decision-making is a fraught area for medical ethics because it deals with the threshold boundaries between childhood and adulthood and Gillick adds a burden upon children and adolescent patients that is unwarranted and through which damage is done to integral human relationships. In light of Gillick, it can be seen that the context of adolescent decision-making and childhood, (...) is a neglected topic of ethical reflection. (shrink)

In recent years there has been growing attention paid to a kind of human action or activity which does not issue from a process of reflection and deliberation and which is described as, e.g., ‘engaged coping’, ‘unreflective action’, and ‘flow’. Hubert Dreyfus, one of its key proponents, has developed a phenomenology of expertise which he has applied to ethics in order to account for ‘everyday ongoing ethical coping’ or ‘ethical expertise’. This article addresses the shortcomings of this approach by examining (...) the pre-reflective ethical know-how individuals first develop and on which all later forms of ethical expertise are dependent. In the first section an account is given of the ‘ethical second nature’ which every individual develops from childhood onwards and which forms the basis of pre-reflective ethical know-how. The acquisition of an ethical second nature early on opens up the very domain of ‘the ethical’ for us in the first place and is constitutive of our sensitivity to it. The second section turns to pre-reflective ethical know-how and whether it is conceptual in nature. Just as sensorimotor understanding forms the basis of our reflective perceptual concepts, pre-reflective ethical know-how is similarly proto-conceptual and is the source of our reflective ethical and moral concepts. Finally, the third section examines the process whereby ethical second nature and pre-reflective ethical know-how are actually acquired, namely, through immersion in an ‘ethical world’. This world consists of both the web of ethical meanings and significances which has evolved in a particular society or community as well as its members whose actions and interactions continually reproduce that web.

This book uses the philosophy of Wittgenstein as a perspective from which to challenge the idea of a critical social theory, represented pre-eminently by Giddens, Habermas and Bhaskar.

This book argues that the institutions of law, and the structures of legal thought, are to be understood by reference to a moral ideal of freedom or independence from the power of others. The moral value and justificatory force of law are not contingent upon circumstance, but intrinsic to its character. Doctrinal legal arguments are shaped by rival conceptions of the conditions for realization of the idea of law. In making these claims, the author rejects the viewpoint of much contemporary (...) legal theory, and seeks to move jurisprudence closer to an older tradition of philosophical reflection upon law, exemplified by Hobbes and Kant. Modern analytical jurisprudence has tended to view these older philosophies as confused precisely in so far as they equate an understanding of law's nature with a revelation of its moral basis. According to most contemporary legal theorists, the understanding and analysis of existing institutions is quite distinct from any enterprise of moral reflection, but the relationship between ideals and practices is much more intimate than this approach would suggest. Some institutions can be properly understood only when they are viewed as imperfect attempts to realize moral or political ideals; and some ideals can be conceived only by reference to their expression in institutions.

__‘Philosophy: The Basics deservedly remains the most recommended introduction to philosophy on the market. Warburton is patient, accurate and, above all, clear. There is no better short introduction to philosophy.’_ - Stephen Law, author of The Philosophy Gym_ _Philosophy: The Basics_ gently eases the reader into the world of philosophy.

What are (...) the limits of free speech? Do you know how science works? Is your mind different from your body? Can you define art? How should we treat non-human animals? For the fifth edition of this best-selling book, Nigel Warburton has added an entirely new chapter on animals, revised others and brought the further reading sections up to date. If you’ve ever asked ‘what is philosophy?’, or wondered whether the world is really the way you think it is, this is the book for you. (shrink)

We attempt in this paper to define a new field of study for philosophy: philosophy of management. We briefly speculate why the interest some managers and management writers take in philosophy has been so little reciprocated and why it needs to be. Then we suggest the scope of this new branch of philosophy and how it relates to and overlaps with other branches. We summarise some key matters philosophers of management should concern themselves with and pursue one in some detail. (...) We conclude with an invitation. (shrink)

Abstractα/β barrels have an ill‐defined origin. Evidence exists which favours their divergent evolution from a common ancestral barrel and convergent evolution to a stable fold. However, recent sequence and structural information for the flavin oxidase/dehydrogenase family of barrel enzymes indicate that sub‐families of α/β barrels have evolved divergently. The modular fusion of barrel domains with core structures from other gene families has also contributed to the evolution of related but catalytically distinct enzyme molecules within each sub‐family of the flavin oxidases/dehydrogenases. (...) An analysis of the structures and sequences of the flavin oxidases/dehydrogenases has now enabled studies focusing on the evolutionary origins and modular assembly of this important family of proteins to be initiated.

This ambitious work apparently has two main aims. The first is to provide a survey of the currently burgeoning field of "Consciousness Studies", presented via the extended metaphor of a horse race whose winning post is a full scientific explanation of consciousness. The second, which receives much more space, is to present Taylor's own cognitive/neuroscientific theory, dubbed "relational consciousness", and to persuade us that it should be the odds-on favourite to win. Neither aim is very well realized.

World Ethics: The New Agenda identifies different ways of thinking about ethics, and of thinking ethically about international and global relations. It also considers several theories of world ethics in the context of issues such as war and peace, world poverty, the environment and the United Nations. The discussion is grounded in an awareness of the post-9/11 world in which we live and offers a more detailed exploration of the idea of global citizenship and a global or cosmopolitan ethic.

Some people commonly know a proposition just in case they all know it, they all know that they all know it, they all know that they all know that they all know it, and so on. They commonly believe a proposition just in case they all believe it, they all believe that they all believe it, they all believe that they all believe that they all believe it, and so on. A long tradition in economic theory, theoretical computer science, linguistics (...) and philosophy has held that people have some approximation of common knowledge or common belief in a range of circumstances, for example, when they are looking at an object together, or when they have just discussed something explicitly in conversation. In this paper, I argue that people do not have any approximation of common knowledge or common belief in these circumstances. The argument suggests that people never have any approximation of common knowledge or common belief. (shrink)

Talk of “essences” has, since Saul Kripke and Hilary Putnam, gained significant currency in contemporary philosophy. It is no longer unfashionable to talk about the essence of this or that (natural) kind, and as such we now find a variety of brands of essentialism on the market including B.D. Ellis’s scientific essentialism, David Oderberg’s real Essentialism, Alexander Bird’s dispositional essentialism, and the contemporary essentialism of Kripke and Putnam. -/- Almost all these brands of essentialism share a particular gloss on Locke’s (...) famous objection to Aristotle that natural kinds are demarcated by nominal essences not real essences. Thus Oderberg claims that ‘Empiricists take [real] essences to be paradigmatically unobservable’ and that this ‘objection goes back at least to John Locke’ (Oderberg 2007: 21). Bird, presenting his dispositional essentialism, defines a notion of “being” as ‘the reverse of Locke’s definition of essence’ which he takes to be ‘the being of any thing, whereby it is what it is’ (Bird 2007: 100). Joseph LaPorte, discussing nominal and real essences, claims that ‘Kripke and Putnam seem to affirm something more substantive: that biological kinds have “real essences” in Locke’s terminology’ (LaPorte 2004: 49). Even avowed anti-essentialists such as John Dupré sanction the standard criticism of Locke that his scepticism about the knowability of real essences was ‘premature’, and claim that ‘genuine natural kinds provide the extensions of many terms of natural language, where these natural kinds are determined by true Lockean real essences’ (Dupré 1993: 22). -/- All of these essentialisms (even Dupré’s anti-essentialism) are wrong about Locke. Oderberg is wrong to claim that Locke thought that real essences were paradigmatically unobservable; Bird is wrong to think that Locke’s notion of essence is the being of anything whereby it is what it is; LaPorte is wrong to think that Kripke and Putnam are talking about Lockean real essences (although so are Kripke and Putnam); and Dupré is wrong to think that genuine natural kinds (if by genuine he means objective or mind-independent) are determined but true Lockean real essences . -/- The mistake stems from a standard, but ultimately incorrect, interpretation of Locke’s discussion of essences in An Essay Concerning Human Understanding . This mistaken interpretation (Lowe 1995, 2006, Von Leyden 1973, Wiggins 1974) takes Locke to mean, by “real essence”, the Aristotelian notion i.e. ‘the very being of anything, whereby it is what it is’ (Essay III.iii.15), and interprets his objection as epistemological: we cannot come to know what real essences are, and therefore they cannot figure in our classifications of things into kinds. -/- This paper will present and defend the following two claims: i) that Locke’s notion of “real essence” is not the Aristotelian notion, and ii) that Locke’s objection to the Aristotelian notion was not merely epistemological. The first claim can be defended by presenting and applying Vienne’s (1993) terminological revision. Vienne argues that Locke did not introduce a dichotomy between real and nominal essence, but a trichotomy between real essence, nominal essence and real constitution. This terminological revision will be employed to highlight where ambiguous uses of the phrase “real essence” have caused some serious misunderstandings of Locke’s philosophy. The second claim (steering Locke around what is the classic objection to his thesis) can be defended by presenting a novel way of splitting up Locke’s objections to the Aristotelian notion of essence. The analysis will show that Locke’s anti-essentialism is still in good shape, and of contemporary significance. (shrink)

Fire is a force that links everyday human activities to some of the most powerful energetic movements of the Earth. Drawing together the energy-centred social theory of Georges Bataille, the fire-centred environmental history of Stephen Pyne, and the work of a number of ‘pyrotechnology’ scholars, the paper proposes that the generalized study of combustion is a key to contextualizing human energetic practices within a broader ‘economy’ of terrestrial and cosmic energy flows. We examine the relatively recent turn towards fossil-fuelled ‘internal (...) combustion’ in the light of a much longer human history of ‘broadcast’ burning of vegetation and of artisanal pyrotechnologies – the use of heat to transform diverse materials. A combustion-centred analysis, it is argued, brings human collective life into closer contact with the geochemical and geologic conditions of earthly existence, while also pointing to the significance of explorative, experimental and even playful dispositions towards energy and matter.

Richard Hooker is one of the greatest theologians of the Church of England. In the light of fierce recent debate, this book argues vigorously against the new orthodoxy that Hooker was a Reformed or Calvinist theologian. In so doing it considers such central religious questions as human freedom, original sin, whether people can deserve salvation, and the nature of religious authority.

For at least two centuries most social thought has taken the earth to be the stable platform upon which dynamic social processes play out. Both climate change and the Anthropocene thesis – with their enfolding of dramatic geologic change into the space-time of social life – are now provoking social thinkers into closer engagement with earth science. After revisiting the decisive influence of the late 18th-century notion of geological formations on the idea of social formations, this introductory article turns to (...) more recent and more explicit attempts to open up the categories of social thought to a deeper understanding of earth processes. This includes attempts to consider how social and political agency is both constrained and made possible by the forces of the earth itself. It also involves efforts to think beyond existing dependencies of social worlds upon particular geological strata and to imagine alternative ‘geosocial’ futures. (shrink)

The word 'athletics' is derived from the Greek verb 'to struggle for a prize'. After reading this book, no one will see the Olympics as a graceful display of Greek beauty again, but as war by other means. Nigel Spivey paints a portrait of the Greek Olympics as they really were - fierce contests between bitter rivals, in which victors won kudos and rewards, and losers faced scorn and even assault. Victory was almost worth dying for, and a number (...) of athletes did just that. Many more resorted to cheating and bribery. Contested always bitterly and often bloodily, the ancient Olympics were not an idealistic celebration of unity, but a clash of military powers in an arena not far removed from the battlefield.
