A scientifically proven method to overcome obstacles and make choices that lead us closer to our goals. WITH A FOREWORD BY MARTINA NAVRATILOVA What do weight gain, poor employee engagement, and climate change all have in common? All three are persistent problems for which solutions are known and readily available. Yet, on an individual and collective level, we continually make choices that lead us not closer to but further away from our stated objectives. Whether we choose the burger and fries (...) over the salad, top-down management over collaboration, or leniency over rigor in combatting climate change, it all comes down to the same thing. The Choice Point. The moment at which we each choose to take an action that we know will undermine our success, but we do it anyway. The Choice Point explains how we experience thousands of thoughts every day: 80 percent are negative, while only 5 percent are new thoughts. We make most of our decisions within two seconds, using mental autopilot systems that we've built through years of experiences, and some of our thoughts (like quitting during a challenge) can compromise our goals. But there's a strategy to change this: Functional Imagery Training (FIT). FIT teaches us how to pick the thoughts that deserve our attention, and how to stop the other, negative thoughts from impacting our actions. Through FIT, we can pause decisions that would typically conflict with our goals, lengthen our Choice Point, and go from passenger to driver of our own minds. Initially developed in 2005 by academics in the UK and Australia, with formal principles emerging through research in 2018, FIT blends motivational interviewing with imagery into a user-friendly model so we can learn, adapt, and adjust our behavior to go beyond what we think is possible.

A variety of recent work in epistemology employs a notion of normality to provide novel theories of knowledge or justification. While such theories are commonly advertised as affording particularly strong epistemic logics, they often make substantive assumptions about the background notion of normality and its logic. This article takes recent normality-based defences of the KK principle as a case study to submit such assumptions to scrutiny. After clarifying issues regarding the natural language use of normality claims, the article isolates a (...) number of choice points regarding the role of contingency, context-sensitivity and similarity in our theorizing with normality. It turns out that both weaker and stronger logics of normality can be motivated depending on how such choices are resolved. And yet securing logics of normality strong enough for normality to play its envisaged role in epistemology may have unwelcome downstream consequences for the resultant theories of knowledge or justification.

Research using the intermodal preferential looking paradigm (IPLP) has consistently shown that English‐learning children aged 2 can associate transitive argument structure with causal events. However, studies using the same methodology investigating 2‐year‐old children’s knowledge of the conjoined agent intransitive and semantic role assignment have reported inconsistent findings. The aim of the present study was to establish at what age English‐learning children have verb‐general knowledge of both transitive and intransitive argument structure using a new method: the forced‐choice pointing paradigm. The (...) results suggest that young 2‐year‐olds can associate transitive structures with causal (or externally caused) events and can use transitive structure to assign agent and patient roles correctly. However, the children were unable to associate the conjoined agent intransitive with noncausal events until aged 3;4. The results confirm the pattern from previous IPLP studies and indicate that children may develop the ability to comprehend different aspects of argument structure at different ages. The implications for theories of language acquisition and the nature of the language acquisition mechanism are discussed. (shrink)

This paper investigates the prospects for a semantic theory that treats disjunction as a modal operator. Potential motivation for such a theory comes from the way in which modals embed within disjunctions. After reviewing some of the relevant data, I go on to distinguish a variety of modal theories of disjunction. I analyze these theories by considering pairs of conflicting desiderata, highlighting some of the tradeoffs they must face.

We study the computational content of the Brouwer Fixed Point Theorem in the Weihrauch lattice. Connected choice is the operation that finds a point in a non-empty connected closed set given by negative information. One of our main results is that for any fixed dimension the Brouwer Fixed Point Theorem of that dimension is computably equivalent to connected choice of the Euclidean unit cube of the same dimension. Another main result is that connected choice (...) is complete for dimension greater than or equal to two in the sense that it is computably equivalent to Weak Kőnig’s Lemma. While we can present two independent proofs for dimension three and upward that are either based on a simple geometric construction or a combinatorial argument, the proof for dimension two is based on a more involved inverse limit construction. The connected choice operation in dimension one is known to be equivalent to the Intermediate Value Theorem; we prove that this problem is not idempotent in contrast to the case of dimension two and upward. We also prove that Lipschitz continuity with Lipschitz constants strictly larger than one does not simplify finding fixed points. Finally, we prove that finding a connectedness component of a closed subset of the Euclidean unit cube of any dimension greater than or equal to one is equivalent to Weak Kőnig’s Lemma. In order to describe these results, we introduce a representation of closed subsets of the unit cube by trees of rational complexes. (shrink)

In many decision scenarios, one has to choose an element from a set S given some reference point e. For the case where S is a subset of a Euclidean space, we axiomatize the choice method that selects the point in S that is closest to e. © 1999 Elsevier Science B.V. All rights reserved.

This paper aims to critique the phenomenon of advanced patient autonomy and choice in healthcare within the specific context of self-testing devices. A growing number of self-testing medical devices are currently available for home use. The premise underpinning many of these devices is that they assist individuals to be more autonomous in the assessment and management of their health. Increased patient autonomy is assumed to be a good thing. We take issue with this assumption and argue that self-testing provides (...) a specific example how increased patient autonomy and choice within healthcare might not best serve the patient population. We propose that current interpretations of autonomy in healthcare are based on negative accounts of liberty to the detriment of a more relational understanding. We also propose that Kantian philosophy is often applied to the healthcare arena in an inappropriate manner. We draw on the philosophical literature and examples from the self-testing process to support these claims. We conclude by offering an alternative account of autonomy based on the interrelated concepts of relationality, care and responsibility. (shrink)

In this paper we establish the proof-theoretic equivalence of (i) $\hbox {\sf ATR}$ and $\widehat{\hbox{\sf ID}}_{\omega}$ , (ii) $\hbox{\sf ATR}_0+ (\Sigma^1_1-\hbox{\sf DC})$ and $\widehat{\hbox {\sf ID}}_{<\omega^\omega} , and (iii) $\hbox {\sf ATR}+(\Sigma^1_1-\hbox{\sf DC})$ and $\widehat{\hbox {\sf ID}}_{<\varepsilon_0} $.

Charland's article suggests that we need to think more about whether decision-making capacity is impaired in severe addiction, working from the idea that drug dealers rely on this understanding of addiction to draw in their clients. Charland argues that it is possible to make a choice without being in control (to make decisions without having decision-making capacity). I argue in support of Charland's ideas by examining the reasons supporting a medical model of addiction and its importance.

The standard topological representation of a Boolean algebra via the clopen sets of a Stone space requires a nonconstructive choice principle, equivalent to the Boolean Prime Ideal Theorem. In this article, we describe a choice-free topological representation of Boolean algebras. This representation uses a subclass of the spectral spaces that Stone used in his representation of distributive lattices via compact open sets. It also takes advantage of Tarski’s observation that the regular open sets of any topological space form (...) a Boolean algebra. We prove without choice principles that any Boolean algebra arises from a special spectral space X via the compact regular open sets of X; these sets may also be described as those that are both compact open in X and regular open in the upset topology of the specialization order of X, allowing one to apply to an arbitrary Boolean algebra simple reasoning about regular opens of a separative poset. Our representation is therefore a mix of Stone and Tarski, with the two connected by Vietoris: the relevant spectral spaces also arise as the hyperspace of nonempty closed sets of a Stone space endowed with the upper Vietoris topology. This connection makes clear the relation between our point-set topological approach to choice-free Stone duality, which may be called the hyperspace approach, and a point-free approach to choice-free Stone duality using Stone locales. Unlike Stone’s representation of Boolean algebras via Stone spaces, our choice-free topological representation of Boolean algebras does not show that every Boolean algebra can be represented as a field of sets; but like Stone’s representation, it provides the benefit of a topological perspective on Boolean algebras, only now without choice. In addition to representation, we establish a choice-free dual equivalence between the category of Boolean algebras with Boolean homomorphisms and a subcategory of the category of spectral spaces with spectral maps. We show how this duality can be used to prove some basic facts about Boolean algebras. (shrink)

Amartya Sen has recently suggested that certain issues which arise in the application of the capability approach can be seen in terms of social choice. This article explores certain connections and tensions between Kenneth Arrow's celebrated discussion of social choice and the capability approach while focusing on one central link: pluralism. Given the variety of values people hold, substantive issues which arise in the application of the capability approach can be seen as social choice problems. Seeing them (...) in this way helps to explain some of Sen's suggestions about applying the approach in the light of an analogue of Arrow's theorem. However, it also poses a potential problem because of the focus on preferences in social choice theory, given that the capability approach is motivated in part by problems which `adaptive preferences' raise for `utility'-based views. In this article, it is argued that Sen's writings about public reasoning allow him to address this problem to some degree. The reading underlying this argument clarifies issues about the relationship between the individual and society in his approach. It also illuminates the extent of Sen's debt to John Rawls's writings on `public reason', while clarifying some points on which Sen and Rawls diverge. Key Words: social choice • capability • welfare • democracy. (shrink)

This paper presents a number of apparent anomalies in rational choice scenarios, and their translation into the logic of everyday reasoning. Three classes of examples that have been discussed in the context of probabilistic choice since the 1960s (by Debreu, Tversky and others) are analyzed in a non-probabilistic setting. It is shown how they can at the same time be regarded as logical problems that concern the drawing of defeasible inferences from a given information base. I argue that (...) initial appearances notwithstanding, these cases should not be classed as instances of irrationality in choice or reasoning. One way of explaining away their apparent oddity is to view certain aspects of these examples as making particular options salient. The decision problems in point can then be solved by ‘picking’ these options, although they could not have been ‘chosen’ in a principled way, due to ties or incomparabilities with alternative options.

In “The Choice Theory of Contracts,” we explain contractual freedom and celebrate the plurality of contract types. Here, we reply to critics by refining choice theory and showing how it fits and shapes what we term the “Contract Canon”. I. Freedom. (1) Charles Fried challenges our account of Kantian autonomy, but his views, we show, largely converge with choice theory. (2) Nathan Oman argues for a commerce-enhancing account of autonomy. We counter that he arbitrarily slights noncommercial spheres (...) central to human interaction. (3) Yitzhak Benbaji suggests that choice theory’s commitment to autonomy is overly perfectionist. Happily, in response to Benbaji, we can cite with approval Charles Fried’s point that contract types are “enabling our liberties.” II. Choice. (4) Aditi Bagchi criticizes our inattention to impediments to choice. We show how choice theory’s commitments to both multiplicity and relational justice ameliorate these impediments. (5) Gregory Klass explores parol evidence to highlight the mechanisms of choice. We substantially concur with his position, and show how such mechanisms can ensure voluntariness, an essential element of choice. (6) Oren Bar-Gill and Clayton Gillette question the institutional capacity of existing legal actors to implement choice theory. Working from the example of cohabitation, we offer a somewhat more optimistic view. III. Contracts. (7) Peter Benson contends our focus on the rational slights the reasonable. Although we did not use this Rawlsian vocabulary, choice theory complies with its strictures — more so than transfer theory. (8) Daniel Markovits and Alan Schwartz claim provocatively that contract theory must: capitulate before pluralism (as they endorse); leverage it; or fall victim to a so-called “embracing” approach (their charge against us). We reject the charge that choice theory is foundationally value-pluralist. Instead, we cabin pluralism and put it to work. (9) The Contract Canon starts on the next big step for choice theory by explaining existing doctrine (rebutting Benson on lack of fit) and helping adjudicate contract practice (countering Markovits and Schwartz on the vices of our pluralism). Each Article in this Issue advances the field; each prompts us to refine choice theory — all steps, we hope, toward a more just and justified law of contract. (shrink)

Social identity poses one of the most important challenges to rational choice theory, but rational choice theorists do not hold a common position regarding identity. On one hand, externalist rational choice ignores the concept of identity or reduces it to revealed preferences. On the other hand, internalist rational choice considers identity as a key concept in explaining social action because it permits expressive motivations to be included in the models. However, internalist theorists tend to reduce identity (...) to desire—the desire of a person to express his or her social being. From an internalist point of view, that is, from a viewpoint in which not only desires but also beliefs play a key role in social explanations as mental entities, this article rejects externalist reductionism and proposes a redefinition of social identity as a net of beliefs about oneself, beliefs that are indexical, robust, and socially shaped.

This textbook provides a survey of the literature of social choice. It integrates the ethical aspects of the subject, with positive aspects of decision mechanisms that centre on the revelation of true preferences. The literature on the subject presently consists of a great many papers. This book draws them together in common notation and points out interpretations which are often missing in specialist papers. Applications in economics, electoral politics, and ethics are discussed. The book will be used by senior (...) undergraduate and graduate students of economics, political science and philosophy as a text book in the subject. (shrink)

This paper refutes the widespread view that disjunctions of imperatives invariably grant free choice between the actions named by their disjuncts. Like other disjunctions they can also express a correlation with some factual distinction, but as with modalized declaratives used for non-assertive speech acts this needs to be indicated explicitly. A compositional analysis of one such indicator, depending on, constitutes the point of departure for a uniform analysis of disjunctions across clause types. Disjunctions are analyzed as sets of (...) propositional alternatives that correlate with a partition that the speaker may or may not be able to indicate explicitly. Free choice arises as the specific case where the partition is induced by the preferences of the addressee. (shrink)

This paper investigates inquisitive extensions of normal modal logic with an existential modal operator taken as primitive. The semantics of the existential modality is generalized to apply to questions, as well as statements. When the generalized existential modality is applied to a question, the result is a statement that roughly expresses that each way of resolving the question is consistent with the available information. I study the resulting logic both from a semantic and from a proof-theoretic point of view. (...) I argue that it can be used for reasoning about a general notion of ignorance, and for reasoning about choice-offering permissions and obligations. The main technical results are sound and complete axiomatizations, both for the class of all Kripke frames, and for any class of frames corresponding to a canonical normal modal logic. (shrink)

The nature of choice and its relation to events in the material world are the subjects of this chapter. In pointing out the relative infrequency of the need to make choices, Clive Staples Lewis' seems to have understood how the making of them now reduces the need for them in the future. Lewis believed the regularity of nature is required for the making of undetermined choices that directly or indirectly cause events in the material world. Lewis concluded that our (...) thinking produces material events that are miraculous in the sense that they would not have occurred had nature proceeded on her own. He also concluded that someone who grasps what the topic of miracles is really about understands that there is nothing per se problematic with divine miracles. Finally, the chapter sets forth an important naturalistic argument against libertarian freedom and explains how Lewis would have responded to it. (shrink)

As a great synthesist for the School of Principles of the Northern and Southern Song dynasties, Zhu Xi’s influence over the School of Principles was demonstrated not only through his positive theoretical creation, but also through his choice and critical awareness. Zhu’s relationship with Confucianism and Buddhism is a typical case; and his activities, ranging from his research of Buddhism (the Chan School) in his early days to his farewell to the Chan School as a student of Li Dong (...) from Yanping and then to his critical awareness of the Chan School, developed in his association with Wang Yingchen, set the entire course of his relationship with Confucianism and Buddhism. It fostered his antagonistic attitude towards the Chan School, which lasted his entire life. Zhu approached the Chan School mainly as an objective social and cultural phenomenon; his discrimination between Confucianism and Buddhism was from an epistemological point of view; and his refutation of the Chan School was mainly from the point of view of language and methodology, an antagonistic attitude of how to face learning. Therefore, his opposition to the Chan School not only directly fostered an awareness of the Confucians of the Ming dynasty against Buddhism, who simply viewed the latter as an external and objective existence, but to a certain extent resulted in the disappearance of the transcendence of the School of Principles, and caused a total change in academic direction during the Ming and Qing dynasties and the formation of the Qianjia Hanxue . What is more, such an opposition to Buddhism continues to influence people’s understanding of the School of Principles. (shrink)

In this volume, Sir Alan Peacock, one of Britain's most noted public economists, poses the question as to whether the history of economic thought is an essential part of the training of public finance economists. He argues that the perspective gained by studying the origins of public choice analysis can offer an important stimulus to scientific progress. The first lecture analyses the increasing popularity in recent years of the modernist, anti-historical point of view. The second criticises those theories (...) of growth in government expenditure which ignore the political process. The third lecture draws on Adam Smith and David Hume to extend the conventional economic model of bureaucracy. In the final lecture, Peacock considers the problem of controlling public sector growth and points to ways of overcoming them. The book ends with short commentaries by seven public economists.

"To be a philosopher and to be a feminist are one and the same thing. A feminist is a woman who does not allow anyone to think in her place."-from _Hipparchia's Choice_ A work of rare insight and irreverence, _Hipparchia's Choice_ boldly recasts the history of philosophy from the pre-Socratics to the post-Derrideans as one of masculine texts and male problems. The position of women, therefore, is less the result of a hypothetical "femininity" and more the fault of exclusion by (...) men. Nevertheless, women have been and continue to be drawn to "the exercise of thought." So how does a female philosopher become a conceptually adventurous woman? Focusing on the work of Sartre and Beauvoir (specifically, his sexism and her relation to it), Michèle Le Doeuff shows how women philosophers can reclaim a place for feminist concerns. Is _The Second Sex_ a work of philosophy, and, if so, what can it teach us about the relation of philosophy to experience? Now with a new epilogue, _Hipparchia's Choice_ points the way toward a discipline that is accountable to history, feminism, and society. (shrink)

We develop here a semiotic model of evolution. We point out the role of confusion and choice as a condition for semiosis, which is a precondition for semiotic learning and semiotic adaptation. Semiosis itself as interpretation and decision-making between options requires phenomenal present. The body structure of the organism is largely a product of former semiosis. The organism’s body together with the structure of the ecosystem serves also as a scaffolding for the sign processes that carry on the (...) ontogenetic cycle and the organisms’ behaviour, providing the experience-based channels for decision making in the indeterminate situations of choice. The stability and persistence of ontogenesis and behaviour are based on the plasticity, or the multiviality of organic dynamics. The same plasticity or multivial dynamics is providing the material for further potential evolution. Evolution has occurred when some change becomes irreversible via its stabilization, and it usually means a modification of existing constraints, or scaffoldings. Some examples of these processes are described in the article. (shrink)

This thesis is an empirical and theoretical exploration of the surprising finding that people often may fail to notice dramatic mismatches between what they want and what they get, a phenomenon my collaborators and I have named choice blindness. The thesis consists of four co-authored papers, dealing with different aspects of the phenomenon. Paper one presents an initial set of studies using a computerised choice procedure, and discusses the relation of choice blindness to the parent phenomenon of (...) change blindness. Paper two is the most central paper of the thesis. In this study, participants were shown pairs of pictures of female faces, and were instructed to choose which face in each pair they found most attractive. In addition, on some trials, immediately after their choice, they were asked to verbally describe the reasons for choosing the way they did. Unknown to the participants, on certain trials, a double-card ploy was used to covertly exchange one face for the other. On these trials, the outcome of the choice became the opposite of what they intended. Counting across all conditions of the experiment no more than a fourth of all such manipulated trials were detected. But not only were the participants in the experiment blind to the manipulation of their choices, they also offered introspectively derived reasons for preferring the alternative they were given instead. A second major conclusion of this paper is that normal participants may produce confabulatory reports when asked to describe the reasons behind their choices. Paper three applies this form of analysis of introspection and confabulation to a second corpus of reports collected within the choice blindness paradigm. In this paper we use word-frequency and latent semantic analysis to contrast the introspective reasons given in non-manipulated and manipulated trials, but very few differences between these two groups of reports were found. In paper four, passer-by shoppers in a local supermarket were invited to sample two different varieties of jam and tea, and to decide which alternative in each pair they preferred the most. After their choice, the participants were asked to again sample to chosen alternative and describe why that one was preferred. At this point, the content of the sample containers were secretly switched, so that the outcome of the choice became the opposite of what the participants intended. No more than a third of the manipulated trials were detected, thus demonstrating considerable levels of choice blindness for the taste and smell of two different consumer goods. (shrink)

In The Harm Principle, Personal Identity and Identity-Relative Paternalism,1 Wilkinson offers a thoughtful argument about medical decision-making and Derek Parfit’s reductionist account of personal identity. I agree that Parfit’s account can contribute to the ethical analysis of patients’ choices.

This book addresses one of the most urgent questions in American society today, one that is currently in the spotlight and hotly debated on all sides: Who shall rule the schools--parents or educators? _School Choice or Best Systems: What Improves Education?_ presents an overview of research and practical applications of innovative--even radical--school reforms being implemented across the United States. These fall along a continuum ranging from "parental choice" to "best systems." At the one extreme are schools of (...) class='Hi'>choice, which allow parents to choose and even govern schools for their children. These include charter schools, traditional private and parochial schools, schools that are privately governed but publicly funded through vouchers, and those that are funded by private scholarships provided by both corporations and wealthy individuals. At the other extreme are centralized state or district systems, based on reform initiatives and new systems of education that have been developed in response to views of citizens and legislators that schools can do much better. These schools, which specify uniform goals, policies, and programs for each school, are highly innovative systems based on research or representing advanced thinking about "what works," and have attracted wide interest. Important questions related to schools of choice and best systems are addressed: How can we choose among schools of choice and best systems? Among the various approaches within each of these alternatives? How can we understand their guiding principles and operational practices? What results do they produce? How can we evaluate their claims? In choosing among the alternatives, how should issues of student achievement, accountability, costs, feasibility, and equity be factored in? This volume brings together leading researchers and education leaders who have carried out the latest studies and advances in the field, providing a forum for them to set forth the arguments and evidence that will be most helpful in making choices for tomorrow's schools. It does not provide a single "right" answer--values and preferences differ across parents, schools, districts, and states. However, there are benefits for all from seeing the rigorous research, challenging thinking, and alternate points of view this volume presents. (shrink)

Taken collectively, consumer food choices have a major impact on animal lives, human lives, and the environment. But it is far from clear how to move from facts about the power of collective consumer demand to conclusions about what one ought to do as an individual consumer. In particular, even if a large-scale shift in demand away from a certain product (e.g., factory-farmed meat) would prevent grave harms or injustices, it typically does not seem that it will make a difference (...) whether one refrains from purchasing that product oneself. Most present-day food companies operate at too large a scale for a single purchase to make a difference to production decisions. If that is true, then it is not clear what point there is in refraining. This is “the problem of collective impact.” This chapter explores a range of proposals for how to solve this problem.

Choice experiment (CE) is a questionnaire based method that the accuracy of research questionnaire determines the validity of the research outcomes. Attribute selection has a prime importance in every CE studies. If respondents do not understand or do not have preference for a certain attribute, the attribute non-attendance problem might happen that biases overall results of the research. Qualitative approaches such as literature review, focus group discussion, and in depth discussion commonly applied in CE researches. However, especially in the (...) developing countries context where ethnical and cultural diversity is a challenge in conducting survey based questionnaires, qualitative methods are not sufficient in selecting attributes. Present study investigates the application of relative importance index (RII) in respondents¡¯ preference for attributes in a modal shift study in Klang Valley, Malaysia. The 5 point Likert scale questions were employed to enhance respondents¡¯ preferences for initial 24 selected attributes. The results of this study showed that from 24 pre-selected attributes, only 18 of them had RII>0.5 and could be included in the final CE design. The results of this study could help researchers to control for unobserved problems in selecting the attributes which could not be discovered through qualitative approaches. -/- . (shrink)

In this response article, we challenge a core assumption that lies at the centre of a round table discussion regarding the Pharmacogenetics to Avoid Loss of Hearing trial. The round table regards a genetic test for a variant (mt.1555A>G) that increases the risk of deafness if a carrier is given the antibiotic gentamicin. The idea is that rapid testing can identify neonates at risk, providing an opportunity to prevent giving an antibiotic that might cause deafness. We challenge the assumption that (...) a positive test unequivocally guides antibiotic choice because, aside from the risk of deafness, all antibiotics for neonatal sepsis are equivalent. We argue that this assumption is faulty and has particularly troubling moral consequences. We claim that giving an alternative to gentamicin is potentially providing inferior treatment and thereby may increase the risk of death. Parents and doctors are faced with a terrible choice as a result of positive point-of-care testing (POCT): give gold-standard treatment and risk deafness or give second line care and risk death. While we do not indicate an answer to this choice, what we do argue is that such a deep and difficult choice is one that may make parents wish genetic testing was never undertaken, and therefore, contra some authors in the round table, provides a reason to gain specific consent for POCT.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Jewish Choices, Jewish Voices: Body ed. by Elliot N. Dorff and Louis E. NewmanGeoffrey ClaussenJewish Choices, Jewish Voices: Body Edited by Elliot N. Dorff and Louis E. Newman Philadelphia: Jewish Publication Society, 2008. 134 pp. $16.00This volume, focused on Jewish attitudes toward the human body, is the first volume of the Jewish Choices, Jewish Voices series published by the Jewish Publication Society. Subsequent volumes focus on money, power, (...) sex and intimacy, war and national security, and social justice. Each volume in the series presents hypothetical case studies involving modern moral questions, a collection of classical and contemporary sources relevant to the case studies, and a collection of short essays by a range of contemporary American Jews reflecting on these materials or on other related issues. Elliot Dorff and Louis Newman, the preeminent scholars of Jewish ethics who edited this first volume in the series, explain in their introduction that they sought to gather together “a variety of authors with many different Jewish beliefs and approaches” (xvi). They do not claim to present “what Judaism says,” but, rather, to anthologize a variety of Jewish perspectives. In doing so, they seek to follow the approach of the Bible and the Talmud, both of which contain “many, many voices articulating often diverse points of view” (xvi).On the other hand, Dorff and Newman reject the idea that “anything goes” when it comes to Jewish views about the body. They indicate that modern American Jews may be tempted to endorse such a perspective, accustomed as they are to the American notion that “I own my body.” But, Dorff and Newman suggest, American Jews would do well to consider the contrary notions that animate much of classical Jewish thought on the body: that God is the true owner of every human body, and that God makes demands about how one should use one’s body. The case studies that follow challenge readers to keep these ideas in mind as they consider duties to limit one’s body weight, refrain from tattooing one’s body, and avoid high-risk behaviors.The essays that make up the heart of this book do by and large embrace Dorff and Newman’s challenge. A few do so quite confidently, such as the one Orthodox contributor to the volume, who declares God’s ownership of human bodies to be “the attitude of Torah Judaism.” But a similar view is also upheld by less traditionally inclined authors such as Adam Goodkind, a college student who expresses his doubts about conventional Jewish observance and theology but who sees the idea of not owning one’s body as reflecting the “common sense” of the Jewish tradition. [End Page 213]Many of the essays are also linked by their view of Judaism as a tradition that does not disparage bodily pleasures. Such pleasures should be greatly valued, a number of authors stress, at least within certain limits. Goodkind takes a stronger stance, opining that “part of being a good Jew is getting a maximum amount of enjoyment out of life” (43). Such talk is not surprising—it fits well with the this-worldly ethos of contemporary American Judaism. But it is worth noting that the more ascetic and otherworldly voices found in the tradition are largely absent from this volume.The volume may not showcase the full breadth of traditional Jewish perspectives, but it does demonstrate how thoughtful and generally liberally minded American Jews do think about key ethical questions when they are asked to consider them through a Jewish lens. And while the essays in the volume are somewhat uneven in quality, they tend to be marked by moral sensitivity and by the creative application of traditional Jewish ideas. This first book in the Jewish Choices, Jewish Voices series offers stimulating reflections about the human body, and it also offers a fine introduction to the patterns of moral reasoning found among many contemporary American Jews.Geoffrey ClaussenElon UniversityCopyright © 2013 Society of Christian Ethics...

This introductory text explores the theory of social choice. This text is an important starting point for students grappling with the complexities of social choice theory. Rigorous yet accessible, with new chapter exercises, it avoids the use of technical language and provides an up-to-date discussion of this rapidly developing field.

Ever since its first publication in 1970, Amartya Sen's paper “The Impossibility of a Paretian Liberal” has served as the starting point for almost all discussions of liberty in social choice theory. However, a number of people, myself included, have argued that Sen's theorem rests on a misleading characterization of liberty . In a recent paper, addressed to a philosophical audience, Sen has provided a careful defence of his theorem against this charge. I shall argue that this defence (...) does not work. (shrink)

Whether we're buying a pair of jeans, ordering a cup of coffee, selecting a long-distance carrier, applying to college, choosing a doctor, or setting up a 401(k), everyday decisions ; both big and small ; have become increasingly complex due to the overwhelming abundance of choice with which we are presented. As Americans, we assume that more choice means better options and greater satisfaction. But beware of excessive choice: choice overload can make you question the decisions (...) you make before you even make them, it can set you up for unrealistically high expectations, and it can make you blame yourself for any and all failures. In the long run, this can lead to decision-making paralysis, anxiety, and perpetual stress. And, in a culture that tells us that there is no excuse for falling short of perfection when your options are limitless, too much choice can lead to clinical depression. In The Paradox of Choice, Barry Schwartz explains at what point choice ; the hallmark of individual freedom and self-determination that we so cherish ; becomes detrimental to our psychological and emotional well-being. In accessible, engaging, and anecdotal prose, Schwartz shows how the dramatic explosion in choice ; from the mundane to the profound challenges of balancing career, family, and individual needs ; has paradoxically become a problem instead of a solution. Schwartz also shows how our obsession with choice encourages us to seek that which makes us feel worse. By synthesizing current research in the social sciences, Schwartz makes the counter intuitive case that eliminating choices can greatly reduce the stress, anxiety, and busyness of our lives. He offers eleven practical steps on how to limit choices to a manageable number, have the discipline to focus on those that are important and ignore the rest, and ultimately derive greater satisfaction from the choices you have to make."--provided by publisher.

The role of the major histocompatibility complex (MHC) in mate choice in humans is controversial. Nowadays, the availability of genetic variation data at genomic scales allows for a careful assessment of this question. In 2008, Chaix et al. reported evidence for MHC‐dependent mate choice among European American spouses from the HapMap 2 dataset. Recently, Derti et al. suggested that this observation was not robust. Furthermore, when Derti et al. applied similar analyses to the HapMap 3 European American samples, (...) they did not see a significant effect. Although some of the points raised by Derti et al. are relevant, we disagree with the reported absence of evidence for MHC‐dependent mate choice within the HapMap samples. More precisely, we show here that the MHC dissimilarity among HapMap 3 European American spouses is still extreme in comparison to the rest of the genome, even after multiple testing correction. This finding supports the hypothesis of MHC‐dependent mate choice in some human populations. (shrink)

This paper proposes a way to understand transformative choices, choices that change ‘who you are.’ First, it distinguishes two broad models of transformative choice: 1) ‘event-based’ transformative choices in which some event—perhaps an experience—downstream from a choice transforms you, and 2) ‘choice-based’ transformative choices in which the choice itself—and not something downstream from the choice—transforms you. Transformative choices are of interest primarily because they purport to pose a challenge to standard approaches to rational choice. (...) An examination of the event-based transformative choices of L. A. Paul and Edna Ullman-Margalit, however, suggests that event-based transformative choices don’t raise any difficulties for standard approaches to rational choice. An account of choice-based transformative choices—and what it is to be transformed—is then proposed. Transformative choices so understood not only capture paradigmatic cases of transformative choice but also point the way to a different way of thinking about rational choice and agency. (shrink)

It is demonstrated that ‘quantum eraser’ experiments do not erase any information. Nor do they demonstrate ‘temporal nonlocality’ in their ‘delayed choice’ form, beyond standard EPR correlations. It is shown that the erroneous erasure claims arise from assuming that the improper mixed state of the signal photon physically prefers either the ‘which way’ or ‘both ways’ basis, when no such preference is warranted. The latter point is illustrated through comparison of the QE spatial state space with the spin-1/2 (...) space of particles in the EPR-spin experiment. (shrink)

This article responds to Professor Romano’s piece in this issue. It concerns our ongoing debate with regard to the desirability of permitting issuers to choose the securities regulation regime by which they are bound. Romano favors issuer choice, arguing that it would result in jurisdictional competition to offer issuers share value maximizing regulations. I, in contrast, believe that abandoning the current mandatory system of federal securities disclosure would likely lower, not increase, U.S. welfare. Each issuer, I argue, would select (...) a regime requiring a level of disclosure less than is socially optimal because its private costs of disclosure would be greater than the social costs of such disclosure. Professor Romano and I agree on most of the basic analytic building blocks for deciding whether issuer choice is a desirable reform: belief in analyzing the problem in terms of the broadly accepted principles of modern financial economics; recognition that disclosure has costs as well as benefits; and acknowledgment that incentives exist for issuers to provide at least some disclosure. We nevertheless reach the opposite conclusion on the desirability of issuer choice. To start, Romano believes that issuers’ private costs of disclosure will not generally be greater than the social costs of such disclosure, whereas I show they will be. Romano argues as well that this is a special case in which any divergence of private and social costs that does exist will not lead to a market failure, at least one possibly correctable by public regulation. I show her argument to be unpersuasive. Finally, Romano interprets the existing empirical evidence as proving mandatory disclosure’s lack of social value, while I show that the evidence in fact does not point in either direction. Where, as here, the theoretical case for the existence of a market failure is strong and the current program for dealing with it is widely admired, the advocate of change should have the burden of proof. Professor Romano has not met this burden. If she is serious about advancing her proposal for issuer choice, she needs to show that despite the market failure inherent in issuer choice, there is inevitably an even greater failure in the regulatory response. Absent such a showing, mandatory disclosure should be retained. (shrink)

Diagnostic self-testing devices are being developed for many illnesses, chronic diseases and infections. These will be used in hospitals, at point-of-care facilities and at home. Designed to allow earlier detection of diseases, self-testing diagnostic devices may improve disease prevention, slow the progression of disease and facilitate better treatment outcomes. These devices have the potential to benefit both the individual and society by enabling individuals to take a more proactive role in the maintenance of their health and by helping society (...) improve health and reduce health costs. However, the full implications of future home-based diagnostic technology for individuals and society remain unclear due to their novelty. We argue that the development of diagnostic tools, especially for home use, will heighten a number of ethical challenges. This paper will explore some of the ethical implications of home-based self-testing diagnostic devices for the autonomous and relational dimensions of the person. This will be facilitated by examining the impact of diagnostic devices for individual autonomy, for the delivery of accurate diagnosis and for the personal significance of the information for the user. The latter will be examined using Charles Taylor's view of personhood and his emphasis on human agency and interpretation. While the ethical issues are not necessarily new, the development of home-based self-testing diagnostic devices will make issues regarding autonomy, accuracy of information and personal significance more and more demanding. This will be the case particularly when an individual's autonomous choices come into conflict with the person's relational responsibilities. (shrink)

Disjunctions in the scope of possibility modals give rise to a conjunctive inference, generally referred to as ‘free choice.’ For example, Emma can take Spanish or Calculus suggests that Emma can take Spanish and can take Calculus. This inference is not valid on standard semantics for modals in combination with a Boolean semantics for disjunction. Hence free choice has sparked a whole industry of theories in philosophy of language and semantics. This paper investigates free choice in sentences (...) involving a non-monotonic modified numeral, under which we embed a possibility modal scoping over disjunction. One example is Exactly one student can take Spanish or Calculus. As we point out, the presence of certain readings of these sentences is a key test for a prominent approach, which analyzes free choice as a kind of scalar implicature. We report on two experiments investigating the readings of such sentences, using an inferential task. Our results are challenging for the implicature approach. We sketch two possible solutions within this approach, either adopting a different recent implicature algorithm, or exploring a different meaning for modified numerals with exactly. Both of them suffer from a variety of problems. We then discuss a third solution, which exploits a recent account of free choice based on homogeneity. This approach can account for our results, in combination with plausible assumptions about homogeneity projection, though it too has open issues with related cases. Regardless of which solution is chosen, non-monotonic contexts turn out to be an important test case for theories of free choice, implicature, and modified numerals. (shrink)

This paper explains the delayed choice quantum eraser of Kim et al. in terms of the transactional interpretation of quantum mechanics by Cramer. It is kept deliberately mathematically simple to help explain the transactional technique. The emphasis is on a clear understanding of how the instantaneous “collapse” of the wave function due to a measurement at a specific time and place may be reinterpreted as a relativistically well-defined collapse over the entire path of the photon and over the entire (...) transit time from slit to detector. This is made possible by the use of a retarded offer wave, which is thought to travel from the slits to the detector and an advanced counter wave traveling backward in time from the detector to the slits. The point here is to make clear how simple the transactional picture is and how much more intuitive the collapse of the wave function becomes if viewed in this way. Also, any confusion about possible retro-causal signaling is put to rest. A delayed choice quantum eraser does not require any sort of backward in time communication. This paper makes the point that it is preferable to use the TI over the usual Copenhagen interpretation for a more intuitive understanding of the quantum eraser delayed choice experiment. Both methods give exactly the same end results and can be used interchangeably. (shrink)

The notion of choice and its individualistic underpinnings is fundamentally inconsistent with the collectivist NHS ethosIn both the policy1 and academic2 literatures, the issue of extending patient choice in the UK National Health Service is currently a much discussed issue. From December 2005—for example, general practitioners will be required to offer patients needing elective surgery the choice of five providers at the point of referral.1 Choice is often thought of as an intrinsically good thing; that (...) is, that people value choice in and of itself.3 A probable underlying reason for this belief is that choice is tied in with the notion of individual autonomy, or freedom, a concept that looms large in ethical theories of the good. Beauchamp and Childress—for example, classified respect for …. (shrink)

In Bermúdez 2013 I argued against David Lewis’s well-known and widely accepted claim that Newcomb’s problem and the prisoner’s dilemma are really notational variants of a single problem. Mark Walker’s paper in this journal takes issue with my argument. In this note I show how Walker’s criticisms are misplaced. The problems with Walker’s argument point to more general and independently interesting conclusions about, first, the relation between deliberation and decision and, second, the differences between the prisoner’s dilemma, which is (...) a strategic choice problem, and Newcomb’s problem, which is a parametric choice problem.

This article is devoted to the problem of ontological foundations of three-dimensional Euclidean geometry. Starting from Bertrand Russell’s intuitions concerning the sensual world we try to show that it is possible to build a foundation for pure geometry by means of the so called regions of space. It is not our intention to present mathematically developed theory, but rather demonstrate basic assumptions, tools and techniques that are used in construction of systems of point-free geometry and topology by means of (...) mereology and Whitehead-like connection structures. We list and briefly analyze axioms for mereological structures, as well as those for connection structures. We argue that mereology is a good tool to model so called spatial relations. We also try to justify our choice of axioms for connection relation. Finally, we briefly discuss two theories: Grzegorczyk’s point-free topology and Tarski’s geometry of solids. (shrink)
