Game-Theoretic Models of Bargaining provides a comprehensive picture of the new developments in bargaining theory. It especially shows the way the use of axiomatic models has been complemented by the new results derived from strategic models. The papers in this volume are edited versions of those given at a conference on Game Theoretic Models of Bargaining held at the University of Pittsburgh. There are two distinct reasons why the study of bargaining is of fundamental importance in economics. The first is (...) that many aspects of economic activity are directly influenced by bargaining between and among individuals, firms, and nations. The second is that bargaining occupies an important place in economic theory, since the 'pure bargaining problem' is at the opposite pole of economic phenomena from the case of 'perfect competition'. This volume is an outgrowth of the renewed interest in the strategic approach to the theory of bargaining and to the general theory of non-cooperative games. (shrink)

Standard practices in experimental economics arise for different reasons. The “no deception” rule comes from a cost-benefit tradeoff; other practices have to do with the uses to which economists put experiments. Because experiments are part of scientific conversations that mostly go on within disciplines, differences in standard practices between disciplines are likely to persist.

Testing economic propositions in laboratory experiments has proven a very fruitful research endeavor in recent years. This volume brings together the major contributors to experimental economics. The papers present their views on the way experiments should be done, on the power and limitations of the techniques, and on the areas in which experimentation could contribute substantially to our understanding of economic behavior. This book distills the main lessons from great experience in experimental work. It will be essential reading for all (...) who wish to follow experimental work or who wish to do such work themselves.

We largely agree with Grimwade et al ’s1 conclusion that challenge trial participants may ethically be paid, including for risk. Here, we add further arguments, clarify some points from the perspective of economics and indicate areas where economists can support the development of a framework for ethically justifiable payment. Our arguments apply to carefully constructed and monitored controlled human infection model trials that have been appropriately reviewed and approved. Participants in medical studies perform a service. Outside the domain of research (...) participation, there is nearly universal agreement that workers providing a service should be compensated fairly, and that work involving more discomfort and risk should be compensated more generously. Accordingly, labour regulations impose floors, not caps on compensation. Caps, even if intended to protect against undue inducement, also raise concerns about illegal price-fixing that disadvantages workers. Such limits on payment for egg donors have successfully been challenged in court.i Moreover, caps on compensation may harm everyone at risk of infection, not just potential participants. Insufficient compensation may impede the recruitment of enough suitable subjects, for example, when representativeness of the subject sample is required. Delays in vaccine development not only prolong disruption of social, educational and economic activity but also lead to excess infections and deaths. Unlike paid CHIM participants, individuals exposed to such infection do not accept it voluntarily, are not compensated for it, and are unlikely to receive the level of medical supervision afforded to closely monitored CHIM participants. Payment caps can lead to attempts to circumvent the regulation. For example, many countries …. (shrink)

Our sense of self includes awareness of our thoughts and movements, and our control over them. This feeling can be altered or lost in neuropsychiatric disorders as well as in phenomena such as “automatic writing” whereby writing is attributed to an external source. Here, we employed suggestion in highly hypnotically suggestible participants to model various experiences of automatic writing during a sentence completion task. Results showed that the induction of hypnosis, without additional suggestion, was associated with a small but significant (...) reduction of control, ownership, and awareness for writing. Targeted suggestions produced a double dissociation between thought and movement components of writing, for both feelings of control and ownership, and additionally, reduced awareness of writing. Overall, suggestion produced selective alterations in the control, ownership, and awareness of thought and motor components of writing, thus enabling key aspects of automatic writing, observed across different clinical and cultural settings, to be modelled.

The study of anarchism as a philosophical, political, and social movement has burgeoned both in the academy and in the global activist community in recent years. Taking advantage of this boom in anarchist scholarship, Nathan J. Jun and Shane Wahl have compiled twenty-six cutting-edge essays on this timely topic in New Perspectives on Anarchism.

The Physician Orders for Life-Sustaining Treatment Paradigm is designed to improve end-of-life care by converting patients' treatment preferences into medical orders that are transferable throughout the health care system. It was initially developed in Oregon, but is now implemented in multiple states with many others considering its use. An observational study was conducted in order to identify potential legal barriers to the implementation of a POLST Paradigm. Information was obtained from experts at state emergency medical services and long-term care organizations/agencies (...) in combination with a review of relevant state law. (shrink)

Legal analysis of survey responses and existing laws identified several potential state legal barriers to a POLST Paradigm implementation. The most potentially problematic barriers are detailed statutory specifications for out-of-hospital DNR protocols. Other potential barriers include limitations on the authority to consent to forgo life-sustaining treatments, medical preconditions, and witnessing requirements for out-of-hospital DNR protocols.

Knowledge of God takes the form of a debate between Alvin Plantinga and Michael Tooley. Plantinga opens the batting with a seventy-page laying out of his case ‘that theism has a significant epistemic virtue: if it is true, it is warranted; this is a virtue naturalism emphatically lacks’. Indeed, Plantinga argues that ‘if naturalism were true, there would be no such thing as knowledge’. It will be recalled [e.g. Plantinga and Plantinga ] that Plantinga's position is that warrant, understood (...) as whatever it is that needs to be added to true belief to …. (shrink)

E.J.Lowe was a prominent and theistically–inclined philosopher who developed and defended a four–category ontology with roots in Aristotle’s Categories. But Lowe engaged in little philosophical theology and said even less about how a divine being might fit into his considered ontology. This paper explores ways in which the reality of a divine being might be squared with Lowe’s ontology. I motivate the exploration with a puzzle that suggests Lowe must reject either divine aseity or the traditional view that God is (...) a substance. After showing that the puzzle cannot be overcome by rejecting one of its premises, I consider ways in which Lowe might try to reject the puzzle wholesale. I argue that the best way to reject the puzzle is to countenance a fifth fundamental category, the category of supernatural substance. (shrink)

The aim of this paper is to sketch a theory of justified belief. What I have in mind is an explanatory theory, one that explains in a general way why certain beliefs are counted as justified and others as unjustified. Unlike some traditional approaches, I do not try to prescribe standards for justification that differ from, or improve upon, our ordinary standards. I merely try to explicate the ordinary standards, which are, I believe, quite different from those of many classical, (...) e. g., ‘Cartesian’, accounts. (shrink)

A first year graduate student, Ann Dee Margulies, changed my research career in 1962 by challenging me to direct her in the isolation of recombination‐deficient mutants of Escherichia coli K‐12. She succeeded in isolating two mutants, which conjugated with donor strains and received the donor DNA, but could not recombine that DNA with their own chromosomes. Ann Dee showed that both mutants were much more sensitive to UV radiation than was the wild type. Furthermore, she showed that one of these (...) mutants carried a single mutation affecting both recombination and resistance. This work, published in 1965, was the first demonstration of the recA gene of E. coli. Subsequent work led to the discovery of many more recombination genes, the phenomenon of post replication‐recombination repair, the invention of the SOS hypothesis and the discovery of genes encoding proteins with similar primary structure and function in all major groups of organisms. This article honors the memory of Ann Dee. (shrink)

This paper presents a partial analysis of perceptual knowledge, an analysis that will, I hope, lay a foundation for a general theory of knowing. Like an earlier theory I proposed, the envisaged theory would seek to explicate the concept of knowledge by reference to the causal processes that produce (or sustain) belief. Unlike the earlier theory, however, it would abandon the requirement that a knower's belief that p be causally connected with the fact, or state of affairs, that p.

I begin with some familiar conceptions of epistemic relativism. One kind of epistemic relativism is descriptive pluralism. This is the simple, non-normative thesis that many different communities, cultures, social networks, etc. endorse different epistemic systems (E-systems), i.e., different sets of norms, standards, or principles for forming beliefs and other doxastic states. Communities try to guide or regulate their members’ credence-forming habits in a variety of different, i.e., incompatible, ways. Although there may be considerable overlap across cultures in certain types of (...) epistemic norms (e.g., norms for perceptual belief), there are sharp differences across groups in other types of epistemic norms.

How can intuitions be used to validate or invalidate a philosophical theory? An intuition about a case seems to be a basic evidential source for the truth of that intuition, i.e., for the truth of the claim that a particular example is or isn’t an instance of a philosophically interesting kind, concept, or predicate. A mental‐state type is a basic evidential source only if its tokens reliably indicate the truth of their contents. The best way to account for intuitions being (...) a basic evidential source is to interpret their subject matter in psychologistic terms. Intuitions provide evidence about the contents of the intuiter's concept, where “concept” is understood as a psychological structure. (shrink)

In order to examine the relationship between warrant and justification, I turn, in this chapter, to the views of Roderick Chisholm, or, more precisely, to the classical Chisholm. In important respects, the classical Chisholm's internalism displays much continuity with the deontological internalism of Descartes and Locke. The classical Chisholm's official position on warrant is that warrant is a matter of fulfilling epistemic obligation – a matter of a proposition's being so related to a person that he can better fulfill his (...) epistemic duty by accepting the proposition in question than by, e.g., withholding acceptance. Against Chisholm, I argue that most of Chisholm's epistemic principles are false if warrant is what Chisholm officially says it is, and that the fulfillment of epistemic duty is neither sufficient nor necessary for warrant.

Among objections to Christian belief, we can distinguish between de facto objections and de jure objections, i.e., between those that claim that Christian belief is false and those that claim that Christian belief, whether or not true, is at any rate unjustifiable, or rationally unjustified, or irrational, or not intellectually respectable, or in some other way rationally unacceptable. In this chapter, I ask whether there is a viable de jure objection to Christian belief formulated in terms of rationality, i.e., I (...) ask whether the objection that Christian belief is not rational is a strong one. In order to assess this sort of objection, we must be clear on what is meant by the term “rational,” and so I distinguish several senses of that term: Aristotelian rationality, rationality as proper function, rationality as within or conforming to the deliverances of reason, means–end rationality, deontological rationality, and William Alston's practical rationality. I conclude that there is no viable de jure objection to Christian belief in terms of any of these senses of rationality, with a possible exception of the second – rationality as proper function. In the next chapter, I begin to explore this remaining possibility and take up the question of the relation between proper function, warrant, and de jure objections to Christian belief. (shrink)

Many current programs for cognitive science sail under the banner of “embodied cognition.” These programs typically seek to distance themselves from standard cognitive science. The present proposal for a conception of embodied cognition is less radical than most, indeed, quite compatible with many versions of traditional cognitive science. Its rationale is based on two elements, each of which is theoretically plausible and empirically well-founded. The first element invokes the idea of “bodily formats,” i.e., representational codes primarily utilized in forming interoceptive (...) or directive representations of one’s bodily states and activities. The second element appeals to wideranging evidence that the brain reuses or redeploys cognitive processes having different original uses. When the redeployment theme is applied to bodily formats of representation, they jointly provide for the possibility that body-coded cognition is a very pervasive sector of cognition. (shrink)

The evaluation of arguments and argumentation is best understood epistemologically. Epistemic circularity is not formally defective but it may be epistemologically objectionable. Sorenson's doubts about the syntactic approach to circularity are endorsed with qualifications. One explanation of an argument's goodness is its ability to produce justified belief in its conclusion by means of justified belief in its premises, but matters are not so simple for interpersonal argumentation. Even when an argument's premises and conclusion are justified for a speaker, this justifiedness (...) may not be transmissible to every hearer. Still, an epistemic approaeh is instructive. Arguing in enthymemes can be legitimate, e.g., because enthymemes can help produce justified persuasion in an audience that supplies the missing premises. (shrink)

This chapter considers how imagination generates emotion. ‘Supposition-imagination’ (S-imagination) is distinguished from ‘enactment-imagination’ (E-imagination). The former kind of imagination involves entertaining or supposing various hypothetical scenarios; with the latter kind of imagination, one tries to create a kind of facsimile of a mental state. Thus, one might try to create a perception-like state as in visual imagination or motoric imagination. It is argued that this much richer form of imagination generates typical emotional reactions to fiction. Emotional reactions to fiction are (...) generated in several different ways, including a process in which we E-imagine being a hypothetical reader or observer of fact. (shrink)

In this chapter, I continue to argue that naturalistic epistemology flourishes best in the garden of supernaturalistic metaphysics. I do so by presenting two epistemological arguments against metaphysical naturalism; the first argument is for the falsehood of naturalism, the second, and more developed, is for the conclusion that it is irrational to accept naturalism. Crucial to both arguments is the estimation of the value of a certain conditional probability, P), where R is the proposition that our cognitive faculties are reliable, (...) N is metaphysical naturalism, E is the proposition that our cognitive faculties arose by way of the mechanisms of evolution, and C is a complex proposition stating what cognitive faculties we have and what sorts of beliefs they produce. In the second argument I contend that it is quite plausible to think either that the rational attitude to take towards the conditional probability mentioned above is the judgment that it is low or that the rational attitude is agnosticism with respect to it, and, in either case, the devotee of N & E has a defeater for any belief he holds, including N. Further, since this defeater is an ultimately undefeated defeater, it is irrational to accept N, since it is irrational to accept any proposition such that one knows one has an ultimately undefeated defeater for it.

The question is: how should a theist think of justification or positive epistemic status? The answer I suggest is: a belief B has positive epistemic status for S only if S’s faculties are functioning properly (i.e., functioning in the way God intended them to) in producing B, and only if S’s cognitive environment is sufficiently similar to the one for which her faculties are designed; and under those conditions the more firmly S is inclined to accept B, the more positive (...) epistemic status it has for her. I conclude by making some qualifications and applications and exmaining some objections. (shrink)

“1950’li yıllarda dönemin büyük felsefecileri arasında dinsel inancı savunan bir kişi bile yoktu. 1990’lı yıllarda Yale’den UCLA’ya, Oxford’dan Heidelberg’e kadar birçok yerde insanın manevi yanını savunan ve geliştiren yüzlerce kitap yazılacak, sel olup akacaktı. Aradaki 40 yıllık süre zarfındaysa sadece ve sadece Alvin Plantinga vardı.” Kelly James Clark Tanrı’nın veya tanrıların varlığı sorusu felsefenin ezeli sorularından biri olagelmişse de Nietzsche’nin Tanrı’nın ölümünü ilan ettiği günden bu yana onu doğrularcasına yaşanan acılar, savaşlar, kötülükler bu konudaki tartışmaların sesini uzun süre bastırdı. (...) Ama özellikle yüzyılın ikinci yarısından sonra palazlanan analitik felsefede meydana gelen “metafiziğe dönüş”, dine yakınlık duyan, en azından dinle ilgilenen filozofların tekrar Yahudi-Hıristiyan ve İslam geleneklerinde anlaşıldığı şekliyle Tanrı’nın varlığına duyulan inancın gerekçelerini yeniden değerlendirmelerine, konuya yeni bir bakış ve araçlarla bakmalarına vesile oldu. Alvin Plantinga’nın bu kitabı, yayımlandığı tarihten itibaren “analitik din felsefesi” alanının da en önemli ve sarsıcı eserlerinden biri hâline geldi ve Tanrı’nın ölmediğini ilan etti. Anselmus’tan Hume’a, Kant ve pozitivistlerden John Mackie gibi modern ateologlara kadar felsefe geleneğiyle hesaplaşan Plantinga, bu abidevi çalışmasında ontolojik, kozmolojik ve teleolojik tanrı kanıtlamalarının eski ve yeni biçimlerinin çıkmazlarını, meziyetlerini ve sunduğu imkânları değerlendiriyor. Tanrı’nın varlığına duyulan inanç ile diğer insanların varlığına ve zihinlerine duyulan inanç arasındaki şaşırtıcı ve sarsıcı bağlantıyı ortaya koyuyor. (shrink)

I begin the chapter by considering the distinction between modality de re and modality de dicto in the works of Aristotle, St. Thomas Aquinas, G. E. Moore, and Norman Malcolm. I then consider two similar objections to modality de re brought by William Kneale and W. V. Quine. Both of these objections fail because they depend on a de re/de dicto confusion. Moreover, I formulate a general rule for correlating propositions that express modality de re with propositions that express modality (...) de dicto. The formulation I offer relies heavily on proper names and I conclude by suggesting further routes of inquiry into the connection between proper names and essentialism. (shrink)

Chapter 6 is an attempt to show that the Theory of Worldbound Individuals —i.e. the theory that any object exists in exactly one possible world—is false, and that there's no good reason to deny that objects exist in more than one world. First, arguments that attempt to show that a denial of TWI entails a contradiction fail, and the so‐called Problem of Transworld Identity is no problem at all. Second, TWI should be rejected because it entails that all of an (...) object's properties are essential to it. The defender of TWI may attempt to defend his view by adopting Counterpart Theory. I conclude by arguing that the Counterpart Theory is both semantically and metaphysically inadequate. (shrink)

In this essay, I raise three topics with regards to Roderick Chisholm's account of the idea of an individual essence. First, I give an argument for the claim that objects have more than one essence. Second, I defend the view that someone can know a proposition entailing someone else's essence. Third, I argue that existentialism is false. I demonstrate this by pointing out that existentialism's central claim – that the proposition E exists and the object x does not is impossible (...) – is false; this proposition turns out to be possible after all on the existentialist account of possibility.
