This book explores the ethical and political implications of the debate between Martin Heidegger and Emmanuel Levinas on the question of Place. It relates their debate to larger disagreements concerning ontology and ethics, the status of humanism, and the relationship between worldliness and transcendence. Ultimately, in an epoch characterized by tribalism and globalization, the Heidegger-Levinas debate illuminates the need for a contemporary politics of place that enables human beings to dwell and practice hospitality.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Hobbes on Demonstration and Construction DAVID GAUTHIER 1~ IN 1656 Hobbes published Six Lessons to the Professors of Mathematics, with an Epistle Dedicatory to the Marquis of Dorchester, Lord Pierrepont. In this Epistle, Hobbes distinguishes the demonstrable from the indemonstrable arts: "demonstrable are those the construction of the subject whereof is in the power of the artist himself, who, in his demonstration, does no more but deduce the consequences of his own operation" . Although this passage, with the (...) explication Hobbes offers for it and the consequences he draws from it, and a similar discussion in De homine, published two years later, have not been unnoticed, their significance for Hobbes's account of science in general, and civil philosophy or politics in particular, has not, I think, been I am grateful to the University of East Anglia for appointing me a Visiting Research Fellow during the period in which the first draft of this paper was written.

Dans «A Society of Individuals», j’esquisse une société qui n’a pas de bien propre, pas de fin sociale, mais qui existe plutôt pour permettre à chacun de ses membres de mieux poursuivre son propre bien, facilitant la coopération et résolvant le problème d’interaction de base, à savoir le fait que la maximisation de l’utilité et l’optimisation Pareto sont parfois incompatibles. Le point de vue orthodoxe défend la rationalité de la maximisation; je défends l’optimisation Pareto. Je soutiens que si nous pouvions (...) fixer les caractéristiques de notre société par un accord préalable, nous nous entendrions sur une société d’individus, et que le fait que nous nous entendions ex ante sur une certaine pratique sociale ou institution est la meilleure justification possible qu’elle constitue pour nous une norme.J’esquisse ensuite quelques-unes des caractéristiques principales de cette société. En faisant cela, je suppose que les membres de la société ne sont pas tous adeptes du contractarianisme, mais qu’ils peuvent soutenir différentes conceptions raisonnables que la société doit chercher à accommoder. Je considère la façon dont plusieurs prétendus droits, comme un droit à certaines ressources, seraient vus dans la société. Et je conclus avec l’idée que le contractarianisme, en faisant valoir que chaque membre adulte de la société doit bénéficier d’une citoyenneté égale, doit permettre à chacun de participer au choix et à la destitution des gouvernements. On peut alors penser que l’émergence d’une société d’individus constitue l’accomplissement de l’idéal démocratique. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Notes and Discussions THE UNITY OF WISDOM AND TEMPERANCE The attempt of Socrates to establish the unity of the virtues has long been an object of philosophic suspicion. Particular attention has been directed to the argument at Protagoras 332a-333b, in which Socrates seeks to demonstrate the unity of wisdom and temperance, by showing that they must be identified as the contrary of folly. The argument proceeds on the assumption (...) that wisdom and temperance are distinct, and so terminates in a contradiction between 'Whatever admits of a contrary admits of one only' and 'Folly, which is one thing, has two contraries, wisdom and temperance.' Scholars have generally rejected Socrates' proof of the second of the contradictory propositions. However, in a recent paper, Professor David Savan has claimed that the contradiction is derived in a formally valid way from premisses which either need no argument or are accepted by Protagoras} My intent in this paper is to cast doubt on this claim, and so to restore the status quo. According to the critics, the weak point in the argument is Socrates' defence of the statement 'Foolish acts and temperate acts are contraries.' But Saran holds that this statement follows from three conditionals, all stated by Socrates and accepted by Protagoras. These conditionals, referred to by Savan as F G and H, will here be termed P1-3. P1 If an act is right and advantageous, then it is temperate. Symbolically: (r.a) D t P2 If an act is wrong, then it is foolish. w~f P3 If an act is foolish, then it is not temperate. fD -t From these, Saran argues, "it follows that 'An act is right' and 'An act is temperate ' are truth functionallyequivalent, as are 'An act is wrong' and 'An act is foolish'.... Since right and wrong are either contraries or contradictories, temperate and foolish acts must also be either contraries or contradictories" (p. 24). Savan then argues that Protagoras, on the basis of his remarks earlier in the dialogue, must take right and wrong to be contradictories, so that temperate and foolish actions are also contradictories, rather than contraries. I want first to consider whether the material equivalences alleged to follow from P1-3 do in fact follow. They may be symbolized: Clr~t C2w =f It is immediately clear that neither C1 nor C2 follows from P1-3. But this is not surprising, because some expression of the relation between 'right' and 'wrong' 1D. Saran, "Socrates'Logic and the Unity of Wisdom and Temperance," in R. J. Butler (ed.), AnalyticalPhilosophy,2nd series(Oxford: BasilBlackwell,1965),pp. 20-26. [157] 158 HISTORY OF PHILOSOPHY must appear among the premises. Since Savan raises the question whether 'right' and 'wrong' are contraries or contradictories only after he claims to establish C1 and C2, we may suppose that the argument should hold whichever relation we assume. If 'right' and 'wrong' are contraries we add the premise: P4A r D --w And ifthey are contradictorieswe add the stronger premise: P4B r -- --w But neither C1 nor C2 follows from PI-3 together with either P4A or P4B. However, it may be urged, the argument fails only because 'advantageous' has been treated as an independent term. P1 should be replaced by: PI* r ~ t We now find that PI*-3 and P4B are sufficientto derive C1 and C2. But PI*-3 and P4A do not suffice.The most we can establish, using only P4A, is the disjunction : C1 vC2r -- t-v-w -- f And this is useless for the purposes of Socrates' argument. One further way of strengthening the premises might be suggested. Instead of dropping 'advantageous' from the argument, one might take it as related both to 'right' and to 'foolish.' That is, one might introduce additional premises from the pairs: P5A r ~ a P5B r - a and: P6A a D -f P6B a ---- -f P5A, added to P1-3 and P4B, will suffice for the derivation of C1 and C2. But no combination of premises not including P4B will do; from P1-3, P4A, P5B and P6B, one can derive C1 but not C2. It is, therefore, necessary to modify Savan's claim in two fairly important...

In 1974, George Grant delivered the Josiah Wood lectures at Mount Allison University on the theme English-Speaking Justice. The lectures, first published in 1978, have been republished, and a volume of later essays on somewhat related themes has recently appeared. Grant's work offers an impressionistic but deep challenge to the conception of justice in modern moral thought and practice, a challenge paralleled, in interesting and important ways, by concerns about morality raised in the writings of such persons as Alasdair MacIntyre, (...) Bernard Williams, and, perhaps more surprisingly, J. L. Mackie. In this review, I want briefly to expound Grant's treatment of justice, to exhibit its relationships to other disquieting accounts, and to suggest some of the resources available to contractarian moral theory for lightening what for Grant is a terrifying darkness.

This particular roundtable falls at the end of a four-year networking project (COST Action IS1307 New Materialism: Networking European Scholarship on ‘How Matter Comes to Matter’) and reflects upon the genealogies of new materialism and how these flow into the individual working practices of participants. The texts below were contributed remotely via email by members of the group, following face-to-face meetings in Barcelona, Maribor, Warsaw, Liverpool, Paris and Utrecht. Authors were unaware of each other’s responses and in this way the (...) dialogue has unfolded a little like a game of Exquisite Corpse or Consequences, with questions acting like a trail of breadcrumbs to follow. Accordingly, the text is the product of a partially bounded experimental system ‘designed to give unknown answers to questions that the experimenters themselves are not yet able to clearly ask’ (Rheinberger 1997: 28). Thus, it both ruminates upon work to date and is intended to generate novel responses from authors and readers alike. (shrink)

These eighty-seven memoirs, anecdotes, and informal recollections by a broad range of reporters reflect both the reality and the myths surrounding this legendary figure. Together, they cover the entire span of Nietzsche's life and yield new insights into Nietzsche as a thinker and as a commentator on his times, recounting his views on religion, philosophy, women, literature, arts, and some of the great thinkers and historical figures.

This study explored calibrating a large item bank for use in multidimensional health measurement with computerized adaptive testing, using both item responses and response time (RT) information. The Activity Measure for Post-Acute Care is a patient-reported outcomes measure comprised of three correlated scales (Applied Cognition, Daily Activities, and Mobility). All items from each scale are Likert type, so that a respondent chooses a response from an ordered set of four response options. The most appropriate item response theory model for analyzing (...) and scoring these items is the multidimensional graded response model (MGRM). During the field testing of the items, an interviewer read each item to a patient and recorded, on a tablet computer, the patient’s responses and the software recorded RTs. Due to the large item bank with over 300 items, data collection was conducted in four batches with a common set of anchor items to link the scale. Van der Linden’s (2007) hierarchical modeling framework was adopted. Several models, with or without interviewer as a covariate and with or without interaction between interviewer and items, were compared for each batch of data. It was found that the model with the interaction between interviewer and item, when the interaction effect was constrained to be proportional, fit the data best. Therefore, the final hierarchical model with lognormal model for RT and the MGRM for response data was fitted to all batches of data via a concurrent calibration. Evaluation of parameter estimates revealed that (1) adding response time information did not affect the item parameter estimates and their standard errors significantly; (2) adding response time information helped reduce the standard error of patients’ multidimensional latent trait estimates, but adding interviewer as a covariate did not result in further improvement. Implications of the findings for follow up adaptive test delivery design are discussed. (shrink)

En 1975, David Gauthier a discuté la question desjeux de coordination purede Schelling et desjeux Hi-Lode Hodgson. Tout en proposant une analyse originale de la façon dont les joueurs rationnels se coordonnent sur des «points focaux», Gauthier a soutenu contre Schelling et Hodgson que dans ces jeux, une coordination réussie ne dépend pas de déviations par rapport aux principes conventionnels du choix rationnel individuel. J’avance que l’analyse de la maximisation contrainte proposée par Gauthier dansMorals by Agreement, (...) qui s’éloigne de façon notoire de la théorie des jeux conventionnelle, présente d’importantes similarités avec les analyses de la coordination de Schelling et Hodgson. La maximisation contrainte peut être envisagée comme une variante pragmatique et contractualiste de l’approche du raisonnement par équipe introduite par Hodgson. (shrink)

Un grand nombre de problèmes dont traite aujourd'hui la théorie de la décision reposent sur des problématiques qui appartiennent à des approches philosophiques, méthodologiques et théoriques fort différentes et dont l'auteur deChoix rationnel et vie publiquedéplore à juste titre l'absence d'unité intrinsèque. En effet, les racines de la théorie contemporaine du choix rationnel ont des ramifications dans trois traditions philosophiques qui ont été maintenues sans entretenir de contacts: théories philosophiques de l'action d'Aristote à Hume, à Kant et à la philosophie (...) analytique de l'action de Davidson; la théorie du conflit de Hobbes à David Gauthier; la théorie de la justice (d'inspiration utilitariste qui a profondément marqué la pensée économique du XXesiècle). Ces branches ont entretenu des interactions sporadiques, mais ces relations n'ont jamais été exploitées systématiquement. Le travail que présente l'auteur est une première tentative dans cette direction, du moins en langue française. (shrink)

Traditional scientific views of rationality are couched in economic terms; choosing an option that does not maximize expectancy is irrational. The construct has been extended metaphorically so that the term “irrational” now describes any decision deemed foolish by the evaluator. For everyday decisions that do not involve money, a decision maker’s utilities are generally not known to an onlooker. Therefore, the pejorative label may be applied inappropriately because the evaluation is distorted by incorrect assessment of the decision maker’s goals. We (...) tie this linguistic confusion to the predominance of gambling studies within decision making research. For noneconomic decisions, we propose an alternative definition, one inspired by a theory of everyday decisions. We label a decision irrational if is inconsistent with a policy previously established by the decision maker. The hierarchical structure of everyday decisions, along with the descriptive multiattribute utility model, are core elements in the theory presented by Weiss et al. (2010 Theory and Decision, 68, 101–114). The theory holds that fast changing considerations are a crucial element in the evaluation of decision options. The momentary salience attached to a consequence can change with current, often fleeting circumstances. An option that would usually be rejected can quickly become too tempting to resist. Most people exhibit this kind of irrationality, violating a personal policy, some of the time—and they are not necessarily foolish to do so. (shrink)

Deception has been practiced by sellers since the beginning of the marketplace. Research in marketing ethics has established benchmarks and parameters forethical behavior that include honesty, full disclosure, equity, and fairness. Deception in marketing, however, has not received the same level of attention. This paper proposes to treat deception in marketing within the context of criminology. By examining deception in marketing within the context of criminology, additional insight can be gained into identifying its antecendents and the likelihood of its occurrence. (...) To this end, deception in marketing is interpreted under the empathy/harm matrix, Cressey’s fraud triangle, and the transparency/time-lag matrix. These frameworks are then combined into a diagram detailing antecedents affecting the likelihood of marketing agents participating in deceptive marketing actions. A number of propositions are presented. (shrink)

Bentham's dictum, ‘everybody to count for one, nobody for more than one’, is frequently noted but seldom discussed by commentators. Perhaps it is not thought contentious or exciting because interpreted as merely reminding the utilitarian legislator to make certain that each person's interests are included, that no one is missed, in working the felicific calculus. Since no interests are secure against the maximizing directive of the utility principle, which allows them to be overridden or sacrificed, the dictum is not usually (...) taken to be asserting fundamental rights that afford individuals normative protection against the actions of others or against legislative policies deemed socially expedient. Such non-conventional moral rights seem denied a place in a utilitarian theory so long as the maximization of aggregate happiness remains the ultimate standard and moral goal. (shrink)

For over half a century there have been concerns about increases in the occurrence of academic misconduct by higher education students and this is now claimed to have reached crisis proportions (e.g. Mostrous & Kenber, 2016a ). This study explores the extent to which multi-national faculty judge the effectiveness of higher education institutions in dealing with such misconduct. A survey of multi-national higher education faculty was conducted to explore the perceived barriers to the implementation of academic integrity processes. It asked (...) faculty how likely some hypothetical scenarios of failures of such processes were to occur in the real world of higher education institutions. 63% of our participants perceived there to be institutional and/or faculty barriers to effectively dealing with academic misconduct. Mostly, they blamed the higher education model for this which, in the interests of mass education, has come to prioritise the need for institutions to focus more on their quantity of output as corporate business enterprises than on the integrity of their output as educators. In discussing participants’ comments, about the relationship of faculty to their employing institutions, Schein and Scheins’ ( 2016 ) theory of three levels of organisational culture was used. Participants’ comments suggested that, at the deepest level of organisational culture i.e. basic underlying taken-for-granted assumptions about beliefs and values, inadequate integrity measures have tended to become normalised. Despite the often considerable, efforts of the institutions, organisational barriers were noted which mitigate against faculty behaving professionally i.e. from doing a ‘good job’ in respect of student academic misconduct. Some blame was also placed on faculty. We argue that apparent institutional inability to effectively manage the integrity process, has potentially significant consequences for wider society. We discuss ways in which this situation might be improved including a recommendation that governments regulate this aspect of the corporate social responsibility of higher education institutions as they do other aspects, requiring that it be managed effectively.

The intervention ladder, developed by the Nuffield Council on Bioethics, is a framework intended to help evaluate the ethical acceptability and justification of public health interventions according to their intrusion on liberty.1 In their recent article, Paetkau2 argues ‘the ladder obscures potential interventions that operate on a systemic rather than individual level’ (p. 1) and that ‘it is crucial that systemic interventions not be left off the table when considering potential concrete interventions’ (p. 3), leading them to propose instead the (...) ‘intervention stairway’. Yet, in this commentary we argue the intervention ladder does not delimit the sorts of public health interventions that may be considered to address a public health issue, although it may speak to their putative justification. Hence, despite its other considerable shortcomings,3 4 there is no need, as Paetkau argues, to broaden the intervention ladder to include systemic factors. Contrary to Paetkau’s claim, the intervention ladder does not preclude policymakers from considering systemic factors’ impact on health outcomes or the public health interventions and strategies that could be implemented to address them. Paetkau adduces the example of measures to protect patients, healthcare workers and healthcare capacity from the threat of infectious diseases. They argue that certain …. (shrink)

[This is an edited version of a keynote talk at the conference on Neural Information Processing Systems (NeurIPS) on November 28, 2022, with some minor additions and subtractions.] -/- There has recently been widespread discussion of whether large language models might be sentient or conscious. Should we take this idea seriously? I will break down the strongest reasons for and against. Given mainstream assumptions in the science of consciousness, there are significant obstacles to consciousness in current models: for example, their (...) lack of recurrent processing, a global workspace, and unified agency. At the same time, it is quite possible that these obstacles will be overcome in the next decade or so. I conclude that while it is somewhat unlikely that current large language models are conscious, we should take seriously the possibility that successors to large language models may be conscious in the not-too-distant future.

In this short introduction, David J. Gunkel examines the shifting world of artificial intelligence, mapping it onto everyday twenty-first century life and probing the consequences of this ever-growing industry and movement. The book investigates the significance and consequences of the robot invasion in an effort to map the increasingly complicated social terrain of the twenty-first century. Whether we recognize it as such or not, we are in the midst of a robot invasion. What matters most in the face of (...) this machine incursion is not resistance, but how we decide to make sense of and respond to the social opportunities and challenges that autonomous machines make available. How to Survive a Robot Invasion is a fascinating and accessible volume for students and researchers of new media, philosophy of technology, and their many related fields. It aims both to assist readers' efforts to understand a changing world and to provide readers with the critical insight necessary for grappling with our science fiction-like future. (shrink)

A model is presented which describes the process decision-makers follow when faced with problems containing ethical dimensions. The model, based upon the empirical literature, is designed to provide guidance to researchers studying ethical behavior in business. The model portrays the decision-maker with a set of personal values which are mediated by elements of the organization's culture. The combination of personal values and organizational influences yields decisions which may be significantly different from those made based upon personal values alone. Inclusion of (...) the personal values of the decision-maker as the dominant individual input and an explicit discussion of the ethical decision process make this model more comprehensive than other recent ethics models.

Personal values have long been associated with individual decision behavior. The role played by personal values in decision making within an organization is less clear. Past research has found that managers tend to respond to ethical dilemmas situationally.

The study examines personal values as they relate to five types of ethical dilemmas. We found a significant positive contribution of altruistic (...) values to ethical decision making and a significant negative contribution of self-enhancement values to ethical decision making.

Although A-consciousness and P-consciousness are conceptually distinct, a refined notion of A-consciousness makes it plausible that the two are empirically inseparable. I suggest that the notion of direct availability for global control can play a central role here, and draw out some consequences.

In response to a recent argument by David Bloor, I argue that denying absolutes does not necessarily lead to relativism, that one can be a fallibilist without being a relativist. At issue are the empirical natural sciences and what might be called “framework relativism”, that is, the idea that there is always a conceptual scheme or set of practices in use, and all observations are theory-laden relative to the framework. My strategy is to look at the elements that define (...) a relativist stance and show where the pragmatic fallibilist disagrees. Defending the pragmatic notion of experience will be central, given that relativists reject the idea that experience can play a role in objectively justifying belief. We can reject all absolutes and start from the premise that everything is historical, contingent, and situated. One of the lessons of pragmatism is that universal and fixed principles are not necessary for objective knowledge. (shrink)

Political advertising to recruit the support of voters is an inherent part of politics. Today, ads are distributed via television and online, including social media. This type of advertisement attempts to recruit support by presenting convincing arguments and evoking various emotions about the candidate, opponents, and policy proposals. We discuss recent arguments and evidence that a specific social emotion, namely the concept kama muta, plays a role in political advertisements. In vernacular language, kama muta is typically labeled as being moved (...) or touched. We compare kama muta and anger theoretically and discuss how they can influence voters’ willingness to support a candidate. We then, for the first time, compare kama muta and anger empirically in the same study. Specifically, we showed American participants short political ads during the 2018 United States midterm election campaigns. All participants saw both kama muta- and anger-evoking ads from both Democratic or Republican candidates. In total, everybody watched eight ads. We assessed participants’ degree of being moved and angered by the videos and their motivation for three types of political support: ideational, financial, and personal. The emotional impact of an ad depended on its perceived source: Participants felt especially angry after watching the anger-evoking ads and especially moved by moving ads if they identified with the political party that had produced the video. Both emotions mediated were associated with increased intentions to provide support. Importantly, if one of the two emotions was evoked, its effect on political support was enhanced if participants identified with the party that had produced the ad. We discuss limitations of the method and implications of the results for future research and practice. (shrink)

It is often thought that Aristotle restricts the scope of justice to existing communities. Against prominent treatments of this problem, this paper argues that while Aristotle does indeed restrict the scope of justice, he recognizes eudaimonic reasons to cultivate co-operative and benevolent relations and to eschew manipulative and exploitative ones. His limitation of justice to existing communities thereby avoids the unsavory implications often attributed to it.

Why is two-dimensional semantics important? One can think of it as the most recent act in a drama involving three of the central concepts of philosophy: meaning, reason, and modality. First, Kant linked reason and modality, by suggesting that what is necessary is knowable a priori, and vice versa. Second, Frege linked reason and meaning, by proposing an aspect of meaning (sense) that is constitutively tied to cognitive signi?cance. Third, Carnap linked meaning and modality, by proposing an aspect of meaning (...) (intension) that is constitutively tied to possibility and necessity. (shrink)

There is a long tradition in philosophy of using a priori methods to draw conclusions about what is possible and what is necessary, and often in turn to draw conclusions about matters of substantive metaphysics. Arguments like this typically have three steps: first an epistemic claim , from there to a modal claim , and from there to a metaphysical claim.
