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.

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)

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.

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.

That Kant’s moral thought is invoked by both advocates and opponents of a right to assisted dying attests to both the allure and and the elusiveness of Kant’s moral thought. In particular, the theses that individuals have a right to a ‘death with dignity’ and that assisting someone to die contravenes her dignity appear to gesture at one of Kant’s signature moral notions, dignity. The purposes of this article are to outline Kant’s understanding of dignity and its implications for the (...) ethics of assisted dying. According to Kant, that which has dignity must be treated as an end in itself and may not permissibly be exchanged for that which merely has price. Kant’s reasoning thus seems to preclude acts of self-killing, including voluntary assisted dying, that rest on individual self-interest, since a person’s interests merely have price. However, a recognizably Kantian view of dignity can permit assisted dying under two sets of circumstances: First, it can be permissible for agents who anticipate a degradation of their rational agency due to conditions such as dementia to direct others to end their lives once sufficiently demented. In so doing, such agents in effect exercise a right to impose obligations on others regarding how their bodies, which will at some future point no longer be the vessels of their rational agency, are to be disposed of. Second, Kant errs in supposing that our dignity can stem solely from our moral personality, i.e., from our capacity to abide by universalizable moral principles. Rather, complete dignity also requires the capacity for setting discretionary ends and the means to those ends, i.e., the dignity of humanity. Individuals with prolonged and intense depression, in severe pain, or with serious disability may lack humanity while retaining their moral personality. In such cases, I propose that their opting to end their lives, with or without the assistance of others, does not amount to exchanging their dignified selves for something which merely has price and is therefore not objectionable on Kantian grounds.

This thought-provoking book discusses the concept of progress in economics and investigates whether any advance has been made in its different spheres of research. The authors look back at the history, successes and failures of their respective fields and thoroughly examine the notion of progress from an epistemological and methodological perspective. The idea of progress is particularly significant as the authors regard it as an essentially contested concept which can be defined in many ways – theoretically or empirically; locally or (...) globally; or as encouraging or impeding the existence of other research traditions. The authors discuss the idea that for progress to make any sense there must be an accumulation of knowledge built up over time rather than the replacement of ideas by each successive generation. Accordingly, they are not concerned with estimating the price of progress, reminiscing in the past, or assessing what has been lost. Instead they apply the complex mechanisms and machinery of the discipline to sub-fields such as normative economics, monetary economics, trade and location theory, Austrian economics and classical economics to critically assess whether progress has been made in these areas of research. -/- Bringing together authoritative and wide-ranging contributions by leading scholars, this book will challenge and engage those interested in philosophy, economic methodology and the history of economic thought. It will also appeal to economists in general who are interested in the advancement of their profession. (shrink)

This paper examines ethical issues involved in the mass marketing of securities to individuals. The marketing of products deemed “socially questionable” or “sinful” (like tobacco and alcohol) has long been recognized as posing special ethical challenges (Kotler, P. and S. Levy: 1971, Harvard Business Review 49, 74–80; Davidson, D. K: 1996, Selling Sin: The Marketing of Socially Unacceptable Products (Quorum Press, Westport). We contend that marketers should consider securities (i.e. common stock, options) in a similar vein, as a potentially dangerous (...) product. Given the inherent volatility of equity prices, responsible marketers need to exercise caution and restraint in promoting securities. We evaluate whether the NYSE’s current guidelines adequately encourage ethical marketing practices and deter unethical ones. Using recent examples of controversial brokerage advertisements, we expose weaknesses in the Exchange’s vague injunction that members not “mislead” reasonable people by making “exaggerated claims” in their communications. From a moral perspective, we find it troublesome that intentionality need not be present for a promotion to be considered misleading. Also problematic is the continued invocation of the reasonable person standard to judge the propriety of advertisements. We close with some thoughts on improving the quality of securities marketing. We suggest that the NYSE, in the interests of fostering higher ethical behavior among member marketers, may need to revive a marketing code of conduct prevalent on Wall Street in an earlier era.

Third generation prospect theory is a theory of choices and of judgments of highest buying and lowest selling prices of risky prospects, i.e., of willingness to pay and willingness to accept. The gap between WTP and WTA is sometimes called the “endowment effect” and was previously called the “point of view” effect. Third generation prospect theory combines cumulative prospect theory for risky prospects with the theory that judged values are based on the integration of price paid or price (...) received with the consequences of gambles. In TGPT, the discrepancy between WTP and WTA is due to loss aversion-losses have greater absolute utility than gains of the same value. TGPT was developed independently of similar developments by Birnbaum and Zimmermann :145–187, 1998) and Luce. This paper reviews theoretical and empirical findings, to show that TGPT fails as a descriptive model of both choices and judgments. Evidence refutes three implications of TGPT, but they are consistent with configural weight models in which loss aversion is not needed to describe the results. In the configural weight models, buyers place greater weight on lower consequences, attributes or estimates of value compared to sellers, who place greater configural weight on higher aspects of an object or prospect.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 29, Number 2, November 2003, pp. 223-266 A Diplomatic Transcription of Hume's "volunteer pamphlet" for Archibald Stewart: Political Whigs, Religious Whigs, and Jacobites M. A. BOX, DAVID HARVEY, AND MICHAEL SILVERTHORNE Many scholars interested in David Hume will have encountered his defense of the beleaguered Archibald Stewart as it appears in an appendix in John Valdimir Price's The Ironic Hume (Austin: University of Texas (...) Press, 1965). Additionally they might know of Price's discussion for The Biblioteck of 1973 of a copy with manuscript markings. A reason for revisiting this pamphlet is that the National Library of Scotland has graciously given permission to reproduce a copy (shelfmark NE.10.e.4) featuring a preface and significant markings in manuscript not in the copy that Price reproduced in his book. As Hume assumes considerable familiarity with the events to which he alludes, we have annotated the text to make it fully intelligible to readers two and half centuries after its composition. The rudimentary bibliographic facts and mysteries are as follows. Two editions survive to us, an octavo (in fours) and a rare duodecimo. Although there is no reason to regard the duodecimo as a second edition correcting or augmenting a first edition, it probably was manufactured after, and was textually derivative from, the octavo. We know nothing of the publishing of M. A. Box is Associate Professor of English, University of Alaska, Fairbanks, PO Box 755720, Fairbanks, AK 99775-5720, USA. David Harvey is at the Classics Department, University of Exeter, Queen's Building, Queen's Drive, Exeter EX4 4QH, UK. Michael Silverthorne is Associate Professor of History, McGiIl University, Stephen Leacock Building, 855 Sherbrooke St. West, Montreal H3A 2T7, Canada, e-mail: [email protected] 224 M. A. Box, David Harvey, and Michael Silverthorne the duodecimo, and doubtless that is as its producers intended. Its title page indicates, like that of the octavo, that the printing was done "for M. Cooper" in 1748, but William Strahan's ledgers register the printing in December 1747 of only the octavo in an edition of 1000 copies.1 The job is listed under bookseller Andrew Millar's account, not Mary Cooper's, probably for the reason that Cooper was a front whose role was to screen the true producers. It is possible that Millar hired someone other than Strahan to print the duodecimo, but it is also possible that someone other than Millar had it printed to mimic the octavo and take the opportunity it offered for concealment.2 A different editorial judgment is evinced in the duodecimo in that cosmetic measures are taken in it to obscure the identities of two military men ridiculed. For example, "Fowke" is rendered as "F—" and "John Cope" as "J-C-----." A digression on Mary Cooper is in order. This remarkable woman (died 1761) took over her husband Thomas's business upon his death 9 February 1743. That business had a history of "publishing" pamphlets and therefore made a plausible front for Millar, who in at least thirty-six other instances, none requiring courage, was willing to have his name appear on a title page with "M. Cooper." (This figure derives from a search by imprints using the English Short-Title Catalogue.) Until Thomas Cooper died, his name appeared on editions of John Armstrong's The Oeconomy of Love (1736 and thereafter) though only Millar's name is listed in the Stationers' Register (Foxon, English Verse A303-A311), and Mary's name is on the title page of the 1753 edition for which Strahan charged Millar (Strahan Papers, Add. MS 48800, s.v. August 1753). It was perhaps in this pattern that the second edition of Hume's heterodox Philosophical Essays (1750) would be reissued in 1751 with a new title page replacing Millar's name with Cooper's. That book was made temporarily a more alarming property by the superstitious panic of the London populace following the winter earthquakes in 1750, presaged by a bloody cloud. Within that year Bishop Thomas Sherlock caused a stir with a pastoral letter (A Letter from the Lord Bishop of London) blaming the earthquakes on several iniquities, "particularly heretical books" (Walpole, Correspondence 20...

Thus far, we know much more about the significant outcomes of perceived ethical leadership than we do about its antecedents. In this study, we focus on multiple types of ethical role models as antecedents of perceived ethical leadership. According to social learning theory, role models facilitate the acquisition of moral and other types of behavior. Yet, we do not know whether having had ethical role models influences follower perceptions of one’s ethical leadership and, if so, what kinds of role models (...) are important. We conducted a field study, surveying supervisors and their subordinates to examine the relationship between three types of ethical role models and ethical leadership: the leader’s childhood role models, career mentors, and top managers. We found that having had an ethical role model during the leader’s career was positively related to subordinate-rated ethical leadership. As expected, this effect was moderated by leader age, such that the relationship between career mentoring and ethical leadership was stronger for older leaders. Leader age also moderated the relationship between childhood models and ethical leadership ratings, such that having had childhood ethical role models was more strongly and positively related to ethical leadership for younger leaders. We found no effect for top management ethical role models. Implications for research and practice are discussed. (shrink)

We are purposive agents; but we—adult humans in a broadly modern world—are more than that. We are reflective about our motivation. We form prior plans and policies that organize our activity over time. And we see ourselves as agents who persist over time and who begin, develop, and then complete temporally extended activities and projects. Any reasonably complete theory of human action will need in some way to advert to this trio of features—to our reflectiveness, our planfulness, and our conception (...) of our agency as temporally extended. These are, further, features that have great significance for the kinds of lives we can live. For these two reasons I will say that these are among the core features of human agency. A theory of human action needs to say what these core features consist in and how they are related to each other. And such a theory needs also to clarify the relation between these core features of our agency and the possibility that we are fully embedded in an event causal order. (shrink)

Cases of modest sociality are cases of small scale shared intentional agency in the absence of asymmetric authority relations. I seek a conceptual framework that adequately supports our theorizing about such modest sociality. I want to understand what in the world constitutes such modest sociality. I seek an understanding of the kinds of normativity that are central to modest sociality. And throughout we need to keep track of the relations—conceptual, metaphysical, normative—between individual agency and modest sociality. In pursuit of these (...) theoretical aims, I propose that a central phenomenon is shared intention. I argue that an adequate understanding of the distinctiveness of the intentions of individuals allows us to provide a construction of attitudes of the participants, and of relevant inter-relations and contexts that constitutes shared intention. I explain how shared intention, so understood, differs from a simple equilibrium within common knowledge. And I briefly contrast my views with aspects of views of John Searle and Margaret Gilbert.

Although computation and the science of physical systems would appear to be unrelated, there are a number of ways in which computational and physical concepts can be brought together in ways that illuminate both. This volume examines fundamental questions which connect scholars from both disciplines: is the universe a computer? Can a universal computing machine simulate every physical process? What is the source of the computational power of quantum computers? Are computational approaches to solving physical problems and paradoxes always fruitful? (...) Contributors from multiple perspectives reflecting the diversity of thought regarding these interconnections address many of the most important developments and debates within this exciting area of research. Both a reference to the state of the art and a valuable and accessible entry to interdisciplinary work, the volume will interest researchers and students working in physics, computer science, and philosophy of science and mathematics.

ABSTRACT:Despite sustained attention to ethical leadership in organizations, scholarship remains largely descriptive. This study employs an empirical approach to examine the consequences of ethical leadership on leader promotability. From a sample of ninety-six managers from two independent organizations, we found that ethical leaders were increasingly likely to be rated by their superior as exhibiting potential to reach senior leadership positions. However, leaders who displayed increased ethical leadership were no more likely to be viewed as promotable in the near-term compared to (...) those who displayed less ethical leadership. Our findings also show ethical culture and pressure to achieve results are important contextual factors that moderate the relationships between ethical leadership and leader promotability to senior leadership roles.

I [try] to understand identification by appeal to phenomena of deciding to treat, and of treating, a desire of one's as reason-giving in one's practical reasoning, planning, and action. Is identification, so understood, "fundamental," as Frankfurt says, "to any philosophy of mind and of action"? Well, we have seen reason to include in our model of intentional agency such phenomena of deciding to treat, and of treating, certain of one's desires as reason-giving. Identification, at bottom, consists in such phenomena — (...) or so I have proposed. Given that such phenomena are important in our practical lives, we may agree with Frankfurt that identification is, in this sense, "fundamental.". (shrink)

During my first year of philosophy study at a German university I shared the prejudice of my colleagues that positivist texts are tedious if not boring, at least compared to Schopenhauer or Nietzsche, to Sartre or other French philosophers. Here is a book that shows the opposite and succeeds in keeping the esprit of an essay over 233 pages. Parrini’s use of the word ‘essay’ alludes to Hume’s Essays, more generally to the English tradition rather than to those contemporaries to (...) whom philosophy is nothing but an essay. Unfortunately, Parrini pays an unnecessary high price for this form when the book’s only footnote informs us that “Reasons of expressive form after all have led me not to burden the text with the usual references to authors and works used. I apologize to the reader. ”1 The expert will easier accept this excuse and, perhaps, enjoy the unencumbered reading, although, as a matter of fact, some footnote-like hints to other authors or even Parrini’s own works are entirely useless without any reference. But, the omittance partly spoils one great merit of the book. As large parts of it are self-contained and Parrini succeeds in making most technical points quite transparent, the essay appears to me very readable for students. To him or her, hardly reading footnotes when going through it first, it becomes almost impossible to penetrate further into ‘positive philosophy’. It would have been much more profitable to the freshmen to supplement the book by a two-page bibliography containing the basic references. The English translation to appear soon will contain references and bibliography in the standard fashion. It is a pity, that unlike the Italian original only few students will be able to afford this fascinating book due to its high price. (shrink)

Suppose you resolve now to resist an expected temptation later while knowing that once the temptation arrives your preference or evaluative assessment will shift in favor of that temptation. Are there defensible norms of rational planning agency that support sticking with your prior intention in the face of such a shift at the time of temptation and in the absence of relevant new information? This article defends the idea that it might be rational to stick with your prior intention in (...) part because of your anticipation of regret in the further future if you were to give in to the temptation. It does this by appeal to the significance of anticipated future regret to the agent ’s present standpoint, and to the role of the agent ’s standpoint in her self-governance. (shrink)

You can sometimes have and be moved by desires which you in some sense disown. The problem is whether we can make sense of these ideas of---as I will say---ownership and rejection of a desire, without appeal to a little person in the head who is looking on at the workings of her desires and giving the nod to some but not to others. Frankfurt's proposed solution to this problem, sketched in his 1971 article, has come to be called the (...) hierarchical model. Indeed, it seems that, normally, if an agent's relevant higher-order attitudes are not to some extent shaped by her evaluative reflections and judgments her agency will be flawed. But this suggests a Platonic challenge to the hierarchical account of ownership. The challenge is to explain why we should not see such evaluative judgments---rather than broadly Frankfurtian higher-order attitudes---as the fundamental basis of ownership or rejection of desire. I do think that a systematic absence of connection between higher-order Frankfurtian attitude and evaluative judgment would be a breakdown in proper functioning. But I want to explain how we can grant this point and still block the Platonic challenge. (shrink)

In autonomous action the agent herself directs and governs the action. But what is it for the agent herself to direct and to govern? One theme in a series of articles by Harry G. Frankfurt is that we can make progress in answering this question by appeal to higher-order conative attitudes. Frankfurt's original version of this idea is that in acting of one's own free will, one is not acting simply because one desires so to act. Rather, it is also (...) true that this desire motivates one's action because one desires that this desire motivate one's action. This latter desire about the motivational role of one's desire is a second-order desire. It is, in particular, what Frankfurt calls a second-order “volition.” And, according to Frankfurt's original proposal, acting of one's own free will involves in this way such second-order, and sometimes yet higher order, volitions.

There is a deeply entrenched view in philosophy and physics, the closed systems view, according to which isolated systems are conceived of as fundamental. On this view, when a system is under the influence of its environment this is described in terms of a coupling between it and a separate system which taken together are isolated. We argue against this view, and in favor of the alternative open systems view, for which systems interacting with their environment are conceived of as (...) fundamental, and the environment's influence is represented via the dynamical equations that govern the system's evolution. Taking quantum theories of closed and open systems as our case study, and considering three alternative notions of fundamentality: (i) ontic fundamentality, (ii) epistemic fundamentality, and (iii) explanatory fundamentality, we argue that the open systems view is fundamental, and that this has important implications for the philosophy of physics, the philosophy of science, and for metaphysics.

I consider two inter-related problems in the philosophy of action. One concerns the role of the agent in the determination of action, and I call it the problem of agential authority. The other concerns the relation between motivating desire and the agent's normative deliberation, and I call it the problem of subjective normative authority. In part by way of discussion of work of Harry Frankfurt and Christine Korsgaard, I argue that we make progress with these problems by appeal to certain (...) kinds of higher-order policies and to their role in the cross-temporal organization of the deliberation and action of temporally persisting agents like us.

Our planning agency contributes to our lives in fundamental ways. Prior partial plans settle practical questions about the future. They thereby pose problems of means, filter solutions to those problems, and guide action. This plan-infused background frames our practical thinking in ways that cohere with our resource limits and help organize our lives, both over time and socially. And these forms of practical thinking involve guidance by norms of plan rationality, including norms of plan consistency, means-end coherence, and stability over (...) time.But why are these norms of rationality? Would these norms be stable under a planning agent's reflection? I try to answer these questions in a way that responds to a skeptical challenge. While I highlight pragmatic reasons for being a planning agent, these need to be supplemented fully to explain the force of these norms in the particular case. I argue that the needed further rationale appeals to the idea that these norms track certain conditions of a planning agent's self-governance, both at a time and over time. With respect to diachronic plan rationality, this approach leads to a modest plan conservatism. (shrink)

From the philosopher’s perspective, the interest in quantum computation stems primarily from the way that it combines fundamental concepts from two distinct sciences: Physics, in particular Quantum Mechanics, and Computer Science, each long a subject of philosophical speculation and analysis in its own right. Quantum computing combines both of these more traditional areas of inquiry into one wholly new, if not quite independent, science. Over the course of this chapter we will be discussing some of the most important philosophical questions (...) that arise from this merger and philosophical lessons to be learned. (shrink)

I argue that our judgements regarding the locally causal models that are compatible with a given constraint implicitly depend, in part, on the context of inquiry. It follows from this that certain quantum no-go theorems, which are particularly striking in the traditional foundational context, have no force when the context switches to a discussion of the physical systems we are capable of building with the aim of classically reproducing quantum statistics. I close with a general discussion of the possible implications (...) of this for our understanding of the limits of classical description, and for our understanding of the fundamental aim of physical investigation. _1_ Introduction _2_ No-Go Results _2.1_ The CHSH inequality _2.2_ The GHZ equality _3_ Classically Simulating Quantum Statistics _3.1_ GHZ statistics _3.2_ Singlet statistics _4_ What Is a Classical Computer Simulation? _5_ Comparing the All-or-Nothing GHZ with Statistical equalities _6_ General Discussion _7_ Conclusion.

A primary goal of quantum computer science is to find an explanation for the fact that quantum computers are more powerful than classical computers. In this paper I argue that to answer this question is to compare algorithmic processes of various kinds and to describe the possibility spaces associated with these processes. By doing this, we explain how it is possible for one process to outperform its rival. Further, in this and similar examples little is gained in subsequently asking a (...) how-actually question. Once one has explained how-possibly, there is little left to do. (shrink)

I flesh out the sense in which the informational approach to interpreting quantum mechanics, as defended by Pitowsky and Bub and lately by a number of other authors, is (neo-)Bohrian. I argue that on this approach, quantum mechanics represents what Bohr called a “natural generalisation of the ordinary causal description” in the sense that the idea (which philosophers of science like Stein have argued for on the grounds of practical and epistemic necessity) that understanding a theory as a theory of (...) physics requires that one be able to “schematise the observer” within it is elevated in quantum mechanics to the level of a postulate in the sense that interpreting the outcome of a measurement interaction, as providing us with information about the world, requires as a matter of principle, the specification of a schematic representation of an observer in the form of a ‘Boolean frame’—the Boolean algebra representing the yes-or-no questions associated with a given observable representative of a given experimental context. I argue that the approach’s central concern is with the methodological question of how to assign physical properties to what one takes to be a system in a given experimental context, rather than the metaphysical question of what a given state vector represents independently of any context, and I show how the quantum generalisation of the concept of an open system may be used to assuage Einstein’s complaint that the orthodox approach to quantum mechanics runs afoul of the supposedly fundamental methodological requirement to the effect that one must always be able, according to Einstein, to treat spatially separated systems as isolated from one another.

In "Action and Responsibility,'' Joel Feinberg pointed to an important idea to which he gave the label "the accordion effect.'' Feinberg's discussion of this idea is of interest on its own, but it is also of interest because of its interaction with his critique, in his "Causing Voluntary Actions,'' of a much discussed view of H. L. A. Hart and A. M. Honoré that Feinberg labels the "voluntary intervention principle.'' In this essay I reflect on what the accordion effect is (...) supposed by Feinberg to be, on differences between Feinberg's understanding of this idea and that of Donald Davidson, and on the interaction between Feinberg's discussion of the accordion effect and his critique of the voluntary intervention principle.
