_ Source: _Volume 95, Issue 3, pp 368 - 413 Frege famously maintained that concepts are not objects. A key argument of Frege’s for this view is, in outline, as follows: if we are to account for the unity of thought, concepts must be deemed _unsaturated_; since objects are, by contrast, saturated entities, concepts cannot be objects. The author investigates what can be made of this argument and, in particular, of the unsaturated/saturated distinction it invokes. Systematically exploring a range of (...) reconstructions suggested by Frege’s writings, and drawing on contemporary work, the author illustrates that no plausible reconstruction is forthcoming. In essence, it is altogether unclear how to simultaneously substantiate, on the one hand, the claim that unsaturated entities must be recognized in order to account for unity and, on the other, the claim that unsaturatedness is incompatible with objecthood.

Reciprocity theory (RT) and costly signaling theory (CST) provide different explanations for the high status of pro-community altruists: RT proposes that altruists are positively and negatively sanctioned by others, whereas CST proposes that altruists are attractive to others. Only RT, however, is beset by first- and higher-order free rider problems, which must be solved in order for RT to explain status allocations. In this paper, several solutions to RT’s free rider problems are proposed, and data about status allocations to Ecuadorian (...) Shuar pro-community altruists are analyzed in light of RT and CST. These data confirm that perceived pro-community altruists are indeed high status and suggest that (1) community residents skillfully monitor the altruism of coresidents, (2) residents who engage in opportunities to broadcast desirable qualities are high status only to the extent that they are considered altruistic, and (3) individuals who sanction coresidents based on coresidents’ contributions to the community are themselves relatively high status. To a greater extent than CST, RT straightforwardly predicts all of these results. (shrink)

One: Being an Investigation into the Unity of Reality and of its Parts, including the Singular Object which is Nothingness, by PriestGraham. Oxford: Oxford University Press, 2015. Pp. xxviii + 252.

Reciprocal altruism involves foregoing an immediate benefit for the sake of a greater long-term reward. It follows that individuals who exhibit a stronger preference for future over immediate rewards should be more disposed to engage in reciprocal altruism – in other words, ‘patient’ people should be more cooperative. The present study tested this prediction by investigating whether participants’ contributions in a public-good game correlated with their ‘discount rate’. The hypothesis was supported: patient people are indeed more cooperative. The paper discusses (...) alternative interpretations of this result, and makes some suggestions for future research.

Frege’s rejection of singular reference to concepts is centrally implicated in his notorious paradox of the concept horse. I distinguish a number of claims in which that rejection might consist and detail the dialectical difficulties confronting the defense of several such claims. Arguably the least problematic such claim—that it is simply nonsense to say that a concept can be referred to with a singular term—has recently received a novel defense due to Robert Trueman. I set out Trueman’s argument for this (...) claim, identifying and remedying some omissions and errors of formulation therein. I then develop a response to the argument by showing, pace Trueman, that it is possible—and how it is possible—to express identities between objects and concepts. (shrink)

The adaptationist framework is necessary and sufficient for unifying the social and natural sciences. Gintis's “beliefs, preferences, and constraints” (BPC) model compares unfavorably to this framework because it lacks criteria for determining special design, incorrectly assumes that standard evolutionary theory predicts individual rationality maximisation, does not adequately recognize the impact of psychological mechanisms on culture, and is mute on the behavioural implications of intragenomic conflict.

It is a remarkable fact about the early history of the analytic tradition that its three most important protagonists all held, at least during significant intervals of their respective careers, that there are entities that cannot be named. This shared commitment on the part of Frege, Russell and the early Wittgenstein is the topic of this thesis. I first clarify the particular form this commitment takes in the work of these three authors. I also illustrate a distinctive cluster of philosophical (...) difficulties attending the view that there are unnameable entities, and explore the relationship between unnameability and inexpressibility. I then investigate what grounds there are for countenancing the unnameable, focussing in particular on the thesis that concepts cannot be named. I give a detailed hearing to four arguments for the unnameability of concepts discernible in, or suggested by, early analytic writings. The first and second arguments (chapters 3 and 4) are distinguishable in the locus classicus, Frege's 'On Concept and Object'. The first concerns the relationship between co-reference and intersubstitutability; the second concerns the unity of thought. The third argument (chapter 4) appeals to the alleged impossibility of expressing identities between objects and concepts, while the fourth (chapter 5) draws on considerations pertaining to diagonalization and Russell's paradox. I make the case that all four arguments fail to provide grounds for accepting the unnameable, contending that each argument can and should be resisted in defence of singular reference to concepts. In doing so I develop a novel defence of the view that absolutely any entity can be referred to with a singular term. (shrink)

In recent philosophy of mathematics avariety of writers have presented ``structuralist''views and arguments. There are, however, a number ofsubstantive differences in what their proponents take``structuralism'' to be. In this paper we make explicitthese differences, as well as some underlyingsimilarities and common roots. We thus identifysystematically and in detail, several main variants ofstructuralism, including some not often recognized assuch. As a result the relations between thesevariants, and between the respective problems theyface, become manifest. Throughout our focus is onsemantic and metaphysical issues, (...) including what is orcould be meant by ``structure'' in this connection. (shrink)

The essays in Rose Lore are a rendering of global cultural history, literature, and metaphysics, woven together in a collection that will be valuable to several disciplines. The essays present numerous qualities of the rose as a symbol with broad cultural, social, and historical meanings: from astrology, to the history of Catholicism, to the new anti-female genital mutilation global movement.

Pragmatists have traditionally been enemies of representationalism but friends of naturalism, when naturalism is understood to pertain to human subjects, in the sense of Hume and Nietzsche. In this volume Huw Price presents his distinctive version of this traditional combination, as delivered in his René Descartes Lectures at Tilburg University in 2008. Price contrasts his view with other contemporary forms of philosophical naturalism, comparing it with other pragmatist and neo-pragmatist views such as those of Robert Brandom and Simon (...) Blackburn. Linking their different 'expressivist' programmes, Price argues for a radical global expressivism that combines key elements from both. With Paul Horwich and Michael Williams, Brandom and Blackburn respond to Price in new essays. Price replies in the closing essay, emphasising links between his views and those of Wilfrid Sellars. The volume will be of great interest to advanced students of philosophy of language and metaphysics. (shrink)

The Politics of the Soul: Eric Voegelin on Religious Experience includes eight essays examining one of the most profound studies of religious experience to appear in the last century: that of the political philosopher Eric Voegelin. Voegelin is increasingly recognized as a political theorist of exceptional scope and erudition and the most important philosopher of his time since Toynbee, and his treatment of religious experience is a crucial part of his overall analysis of existence and history. This collection of essays (...) by prominenet Voegelin scholars is the first book to explore the relevance of that analysis to the contemporary understanding of political theory, theology, history, and philosophy of consciousness, and as such it constitutes a significant contribution not only to Voegelin scholarship but to the current quest for theoretical foundations.

Wilfrid Sellars's "Empiricism and the Philosophy of Mind" begins with an argument against sense-datum epistemology. There is some question about the validity of this attack, stemming in part from the assumption that Sellars is concerned with epistemic foundationalism. This paper recontextualizes Sellars's argument in two ways: by showing how the argument of EPM relates to Sellars's 1940s work, which does not concern foundationalism at all; and by considering the view of H.H. Price, Sellars's teacher at Oxford and the only (...) classical datum theorist to receive substantive comment in EPM. Timm Triplett has claimed that Sellars's discussion simply begs the question against Price, but this depends on the mistaken assumption that Sellars's concern is with foundationalism. On the contrary, Sellars's argument concerns the assumption that the innate capacity for sensory experience counts as "thinking in presence" in the way needed for empiricist accounts of content acquisition. Price's distinction between noticing universals and being aware of them encapsulates the tensions empiricists face here. (shrink)

Like William James before him, Huw Price has influentially argued that truth has a normative role to play in our thought and talk. I agree. But Price also thinks that we should regard truth-conceived of as property of our beliefs-as something like a metaphysical myth. Here I disagree. In this paper, I argue that reflection on truth's values pushes us in a slightly different direction, one that opens the door to certain metaphysical possibilities that even a Pricean pragmatist (...) can love.

Argues that, having been forced to give up realism about material objects, naturalists are committed to accepting constructivism, the view that the modal properties of material objects are mind‐dependent. Also argues that, in accepting constructivism, naturalists must give up materialism. Finally, shows that, once materialism has been given up, standard arguments against mind‐body dualism turn their teeth against realism about other minds.

Rationale Treatment guidelines recommend a more conservative surgical approach than mastectomy for early stage breast cancer and a stronger emphasis on adjuvant therapy. Registry data at South Australian teaching hospitals have been used to monitor survivals and treatment in relation to these guidelines.Aims and objectives To use registry data to: (1) investigate trends in survival and treatment; and (2) compare treatment with guidelines.Methods Registry data from three teaching hospitals were used to analyse trends in primary courses of treatment of breast (...) cancers during 1977–2003 (n = 4671), using univariate analyses and multiple logistic regression. Disease-specific survivals were analysed using Kaplan–Meier product limit estimates and multivariable Cox proportional hazards regression.Results The 5-year survival was 79.9%, but with a secular increase, reaching 83.6% in 1997–2003. The relative risk of death (95% confidence limits) was 0.74 (0.62, 0.88) for 1997–2003, compared with previous diagnoses, after adjusting for tumour node metastasis stage, grade, age and place of residence. Treatment changes included an increase in conservative surgery (as opposed to mastectomy) from 51.7% in 1977–1990 to 76.8% in 1997–2003 for stage I (P < 0.001) and from 31.1% to 52.2% across these periods for stage II (P < 0.001). Adjuvant radiotherapy also became more common (P < 0.001), with 20.6% of patients receiving this treatment in 1977–1990 compared with 60.7% in 1997–2003. Radiotherapy generally was more prevalent when conservative surgery was provided, although also relatively common in mastectomy patients when tumour diameters exceeded 50 mm or when there were four or more involved nodes. The proportion of patients receiving chemotherapy increased (P < 0.001), from 19.6% in 1977–1990 to 36.9% in 1997–2003, and the proportion having hormone therapy also increased (P < 0.001), from 34.3% to 59.4% between these periods.Conclusions Survivals appear to be increasing and treatment trends are broadly consistent with guideline directions, and the earlier research on which these recommendations were based.

The arguments for redistribution of wealth, and for prohibiting certain transactions such as price-gouging, both are based in mistaken conceptions of exchange. This paper proposes a neologism, “euvoluntary” exchange, meaning both that the exchange is truly voluntary and that it benefits both parties to the transaction. The argument has two parts: First, all euvoluntary exchanges should be permitted, and there is no justification for redistribution of wealth if disparities result only from euvoluntary exchanges. Second, even exchanges that are not (...) euvoluntary should generally be permitted, because access to market exchange may be the only means by which people in desperate circumstances can improve their position.

This important book includes a compelling selection of original essays on euthanasia and associated legislative and health care issues, together with important background material for understanding and assessing the arguments of these essays. The book explores a central strand in the debate over medically assisted death, the so called "slippery slope" argument. The focus of the book is on one particularly important aspect of the downward slope of this argument: hastening the death of those individuals who appear to be suffering (...) greatly from their medical condition but are unable to request that we do anything about that suffering because of their diminished mental capacities. Slippery slope concerns have been raised in many countries, including Britain, the Netherlands, Canada, and the United States. This book concentrates most of its attention on the latter two countries. Stingl divides the book into four parts. Part I lays out the relevant public policies in the form of legal judgments, making them the philosophical point of departure for readers. Part II discusses the ever-present slippery slope objection to assisted suicide and other forms of euthanasia. Parts III and IV examine the role of social factors and political structures in determining the morality and legalization of voluntary and non-voluntary euthanasia. These sections are especially valuable. The inclusion of a selection of papers on the relationship between the morality and legality of euthanasia and systems of health care delivery is of particular interest, especially to those who want to make statistical, legal and moral comparisons between the USA and Canada.

Therewas strong consensus that the current economicstructure of agriculture cannot adequatelyaddress major issues of concern to society:farm incomes, food security and safety, theneeds of developing countries, animal welfare,and the environment. This economic structure isbased primarily on competition betweenproducers and between retailers, driving foodprices down, combined with externalization ofmany costs. These issues must be addressed (...) by acombination of legislation, restructuring ofthe market, and use of public funds. Themeeting included workshops that made otherrecommendations for research and education.

Much recent discussion surrounding valuation of the arts and culture, particularly in the policy arena, has been dominated by a concern to identify an economic and financial basis for valuation of art works, arts, activities and more general ways in which we express our culture. Whereas a great deal can be gained from a fuller understanding of the economic value of art, there is a real danger that financial considerations will tend to crowd out all other aspects of value. This (...) book moves beyond the limitations implicit in a narrow economic approach, bringing different disciplinary viewpoints together, opening up a dialogue between scholars about the processes of valuation that they use and exploring differences and identifying common ground between the various viewpoints. The book's common theme – the tension between economic and cultural modes of evaluation – unites the chapters, making it a coherent and unified volume that provides a new and unique perspective on how we value art.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

While we’re inclined to think that a person is “above all price,” we in fact make a lot of decisions that seem to set a price on persons—or, at least, on their life. For example, I was recently involved with setting standards for buildings in areas susceptible to earthquakes. The consensus seemed to be $3/sq. ft. increase in construction cost was reasonable, more than that was not, even though lives could be saved if the standard were higher, assuring (...) the survival of more buildings. Though the Ford Pinto remains the classic case of unjustifiably putting a price on persons, it is at once not such a clear case and also useful for thinking about when putting a price on life can be justified.

This book offers a unified treatment of selected topics in the theory of financial markets. Starting with discrete time models, Dothan introduces discrete time stochastic calculus and discrete martingale methods of intuitive simplicity to characterize attainability, completeness, pricing, and the relationship between risk and return in financial markets. Subsequently, he uses the intuition developed in conjunction with the discrete time theory to introduce continuous time calculus for continuous, jump, and mixed continuous-jump processes, and to deal with attainability, completeness, pricing, and (...) the relationship between risk and return in general continuous time models. Throughout, the exposition of the continuous time theory emphasizes the analogies between discrete time and continuous time methods and results. The book includes many examples, applications to the pricing of options and other derivative securities, and an extensive discussion of the Black-Scholes model and its most general theoretical extension.

This book is available either individually, or as part of the specially-priced Arguments of the Philosphers Collection.

The theory of the just price is commonly assumed to have three sources: Political philosophy of Greek antiquity, scholastic ethics of the High Middle Ages, and the Roman law of obligations of late antiquity. While closer inspection confirms this holds for the first two worlds of thought the latter assumption seems ultimately unfounded. The paper claims that the evidence notoriously presented on behalf of that assumption – two rescripts attributed to Roman emperor Diocletian, namely Codex Iustinianus 4.44.2 and 4.44.8 (...) – ultimately points in another direction. Offering both an analysis and an alternative reading of the rescripts an integrated interpretation is given that reconciles them with the “liberalistic spirit of Roman law”. Also, it is explained why, from the point of view of legal and social philosophy, the fact that Roman law refrains from introducing a moral aspect to the institute of price fixing speaks in favour of Roman law rather than against it.

This paper contributes to the (re-)conceptualisation of responsible innovation by proposing an evolutionary economic approach that focuses on the role of consumers in the innovation process. After a discussion of the philosophical foundations and ethical implications of this approach, which bears an explanatory potential that has not been adequately considered in previous discussions of responsible innovation, we present a first step towards capturing the important but often neglected role of consumers in innovation processes (including responsible innovation): We propose an agent-based (...) model that incorporates a multidimensional space of characteristics in which new products or services are represented by more than the mere aspect of price and quality. Instead, innovations are denoted by a large set of characteristics, including also negative or harmful ones. The model is used to illustrate that consumers’ heterogeneity and bounded rationality – even if considered in a simple manner – indeed play a crucial role in the creation and diffusion of responsible innovation which can and should be used for further work in this field and for possible extensions of the model.

Genetic variability and diversity are the result of a mutation-selection balance that acts permanently within and between species. The presence of deleterious mutations is a necessary consequence of this process and thus the price paid by a species for its capacity for further evolution (Haldane 1937, Am Nat 71:337–349). Recent estimations of mutation rate in the human lineage has revived the debate as to whether the high number of deleterious mutations poses a severe problem for the future of mankind. (...) Theoretical considerations allow a scenario in which the survival of the human race is maintained by truncation selection of deleterious mutations that removes as many mutations as appear anew in every generation. In this case our genetic burden is carried by those individuals that suffer a genetic death resulting from random distribution of deleterious alleles. Nevertheless, one has to ask whether the mutation rate may set absolute limits on the complexity of a species. (shrink)

ABSTRACT:The ethics of high frequency trading are obscure, due in part to the complexity of the practice. This article contributes to the existing literature of ethics in financial markets by examining a recent trend in regulation in high frequency trading, the prohibition of deception. We argue that in the financial markets almost any regulation, other than the most basic, tends to create a moral hazard and increase information asymmetry. Since the market’s job is, at least in part, price discovery, (...) we argue that simplicity of regulation and restraint in regulation are virtues to a greater extent than in other areas of finance. This article proposes criteria for determining which high-frequency trading strategies should be regulated. (shrink)
