Philosophers of well-being have tended to adopt a foundationalist approach to the question of theory and measurement, according to which theories are conceptually before measures. By contrast, social scientists have tended to adopt operationalist commitments, according to which they develop and refine well-being measures independently of any philosophical foundation. Unfortunately, neither approach helps us overcome the problem of coordinating between how we characterize well-being and how we measure it. Instead, we should adopt a coherentist approach to well-being science.

Generating an account that can sidestep the disagreement among substantive theories of well-being, while at the same time still providing useful guidance for well-being public policy, would be a significant achievement. Unfortunately, the various attempts to remain agnostic regarding what constitutes well-being fail to either be an account of well-being, provide useful guidance for well-being policy, or avoid relying on a substantive well-being theory. There are no theory-free lunches in well-being policy. Instead, I propose an intermediate account, according to which (...) well-being is constituted by endorsed veridical experiences. This account refers back to theories of well-being but does so as agnostically as possible. An intermediate account of well-being is meant as a policy guiding compromise between the different theories of well-being that make claims regarding what constitutes well-being. An intermediate account does as well as can be hoped for in providing a basis for well-being policy. (shrink)

It is an open question whether well-being ought to primarily be understood as a temporal concept or whether it only makes sense to talk about a person’s well-being over their whole lifetime. In this article, I argue that how this principled philosophical disagreement is settled does not have substantive practical implications for well-being science and well-being policy. Trying to measure lifetime well-being directly is extremely challenging as well as unhelpful for guiding well-being public policy, while temporal well-being is both an (...) adequate indirect measure of lifetime well-being, and an adequate focus for the purposes of improving well-being through public policy. Consequently, even if what we ought to care about is lifetime well-being, we should use temporal measures of well-being and focus on temporal well-being policies. (shrink)

Spoofing is the act of placing orders to buy or sell a financial contract without the intention to have those orders fulfilled in order to create the impression that there is a large demand for that contract at that price. In this article, I deny the view that spoofing in financial markets should be viewed as morally permissible analogously to the way bluffing is permissible in poker. I argue for the pro tanto moral impermissibility of spoofing and make the case (...) that spoofing is disanalogous from bluffing in at least one important regard—speculative trading serves an important economic role, whereas poker does not.

Policy-makers sometimes aim to improve well-being as a policy goal, but to do this they need some way to measure well-being. Instead of relying on potentially problematic theories of well-being to justify their choice of well-being measure, Daniel Hausman proposes that policy-makers can sometimes rely on preference-based measures as evidence for well-being. I claim that Hausman’s evidential account does not justify the use of any one measure more than it justifies the use of any other measure. This leaves us at (...) a loss as to which policy should be chosen in the non-trivial cases for which there is substantial disagreement between the different measures in their assessment of policy.

Many philosophers reject the view that well-being over a lifetime is simply an aggregation of well-being at every moment of one's life, and thus they reject theories of well-being like hedonism and concurrentist desire satisfactionism. They raise concerns that such a view misses the importance of the relationships between moments in a person's life or the role narratives play in a person's well-being. In this article, we develop an atomist meta-theory of well-being, according to which the prudential value of a (...) life depends solely on the prudential value of each moment of that life. This is a general account of momentary well-being that can capture different features of well-being that standard atomistic accounts fail to capture, thus allowing for the possibility of an atomism that is compatible with a variety of well-being theories. Contrary to many criticisms leveled against momentary well-being, this well-being atomism captures all of the important features of well-being. (shrink)

in recent years, policy makers have shown increasing interest in implementing policies aimed at promoting individual well-being. But how should policy makers choose their well-being policies? a seemingly reasonable first step is to settle on an agreed-upon definition of well-being. yet there currently is significant disagreement on how well-being ought to be characterized, and agreement on the correct view of well-being does not appear to be forthcoming. Nevertheless, i argue in this paper that there are several reasons to think that (...) the domain of well-being in the public policy context is narrower than that of well-being in general, which makes agreement on how to understand well-being in the public policy context more likely.

According to what I call the ‘argument from public bads’, if a researcher deceived subjects in the past, there is a chance that subjects will discount the information that a subsequent researcher provides, thus compromising the validity of the subsequent researcher’s experiment. While this argument is taken to justify an existing informal ban on explicit deception in experimental economics, it can also apply to implicit deception, yet implicit deception is not banned and is sometimes used in experimental economics. Thus, experimental (...) economists are being inconsistent when they appeal to the argument from public bads to justify banning explicit deception but not implicit deception. (shrink)

In book II of Plato’s Republic, Socrates discusses the cities of necessity and luxury (372d-373a). Discussions of these cities have often focused on citizens desiring more than they need, which creates a demand for luxury. Yet the second part of the equation, which is not usually recognized, is that there must be sufficient supply to meet this demand. The focus of this article is on the importance of supply in the discussion of the first two cities in book II of (...) the Republic. This article argues that the way Plato models the cities makes it the case that a surplus above levels of necessity will be generated from time to time. That the unwanted surplus cannot be spontaneously disposed of entails that the first two cities are institutionally incomplete. A government is needed in order to coordinate the disposal of the surplus supply the city will produce. (shrink)

The move from open outcry to electronic trading added another responsibility to futures exchanges—that of matching orders between buyers and sellers. Matching systems can affect the level and speed of price discovery, the distribution of revenue, as well as the level of price efficiency of a given market. Whether the matching system is procedurally fair is another important consideration. I argue that while FIFO (First In First Out) is a fair procedure in principle and is perceived as the default matching (...) system, it is not a fair procedure in practice. Likewise, while pro rata is a fair procedure in principle, it is not so in practice. Nevertheless, both FIFO and pro rata are relics of an open outcry system. Instead, I propose an alternative approach to matching systems that builds on the strengths of electronic trading—the ability to randomize in real time. I introduce random selection for service (RSS) as a matching system that is procedurally fair both in principle and in practice. (shrink)

Some advances in bioethics regarding ethical considerations that arise in the context of medical research can also be relevant when thinking about the ethical considerations that arise in the context of SoTL research. In this article, I aim to bring awareness to two potential ethical challenges SoTL researchers might face when playing a dual role of teacher and researcher that are similar to the challenges physicians face in their dual role of physician and researcher. In this article, I argue that (...) two commonly discussed concerns in bioethics---the need for clinical equipoise and the possibility of a therapeutic misconception---have analogies when conducting some types of research on students. I call these counterparts educational equipoise and the educational misconception. (shrink)

Alasdair MacIntyre argues that moral virtues are antithetical to what is required of those who trade in financial markets to succeed. MacIntyre focuses on four virtues and argues that successful traders possess none of them: (i) self-knowledge, (ii) courage, (iii) taking a long-term perspective, and (iv) tying one’s own good with some set of common goods. By contrast, I argue that (i)–(iii) are, in fact, traits of successful traders, regardless of their normative assessment. The last trait – caring about the (...) common good – is often counterproductive in most for-profit ventures, including trading, and so singling out traders is inappropriate. (shrink)

In this paper we discuss James Buchanan’s contribution in the narrow domain of understanding committee voting under majority rule. We then go on to discuss Charles Plott’s seminal experimental work on the topic that sparked a wave of public choice experimental work. However, given Plott’s claims that Buchanan influenced him significantly, it is puzzling that his work with Morris Fiorina explores a question outside of those which Buchanan and Tullock found interesting. We suggest several ways to resolve this tension. Our (...) chapter concludes by discussing a lacuna in the experimental public choice literature in which Buchanan was particularly interested—logrolling, or vote trading. (shrink)

Many believe that the lack of correlation between happiness and income, first discovered by Richard Easterlin in 1974, entails the conclusion that well-being policies should be made based on happiness measures, rather than income measures. I argue that distinguishing between how well-being is characterized and how that characterization is measured introduces ways of denying the conclusion that policies should be made based on happiness measures. It is possible to avoid the conclusion either by denying that well-being hedonism is true or (...) by denying that happiness measures are a better way of operationalizing hedonism than income measures are. By making these possibilities explicit, we find that less hinges on whether income and happiness are correlated than is often thought. (shrink)

This review article provides a new perspective on the ethics of green nudging. We advance a new model for assessing the ethical permissibility of green nudges (GNs). On this model, which provides normative guidance for policymakers, a GN is ethically permissible when the intervention is (1) efficacious, (2) cost-effective, and (3) the advantages of the GN (i.e. reducing the environmental harm) are not outweighed by countervailing costs/harms (i.e. for nudgees). While traditional ethical objections to nudges (paternalism, etc.) remain potential normative (...) costs associated with GNs, any such costs must be weighed against the injunction to reduce environmental harm to third parties.

The medical profession is observing a rising number of calls to action considering the threat that climate change poses to global human health. Theory-led bioethical analyses of the scope and weight of physicians’ normative duty towards climate protection and its conflict with individual patient care are currently scarce. This article offers an analysis of the normative issues at stake by using Korsgaard’s neo-Kantian moral account of practical identities. We begin by showing the case of physicians’ duty to climate protection, before (...) we succinctly introduce Korsgaard’s account. We subsequently show how the duty to climate protection can follow from physicians’ identity of being a healthcare professional. We structure conflicts between individual patient care and climate protection, and show how a transformation in physicians’ professional ethos is possible and what mechanisms could be used for doing so. An important limit of our analysis is that we mainly address the level of individual physicians and their practical identities, leaving out important measures to respond to climate change at the mesolevels and macrolevels of healthcare institutions and systems, respectively.

We present four new change detection methods that create an automated change map from a probability map. In this case, the probability map was derived from a 3D model. The primary application of interest is aerial photographic applications, where the appearance, disappearance or change in position of small objects of a selectable class (e.g., cars) must be detected at a high success rate in spite of variations in magnification, lighting and background across the image. The methods rely on an earlier (...) derivation of a probability map. We describe the theory of the four methods, namely Bernoulli variables, Markov Random Fields, connected change, and relaxation-based segmentation, evaluate and compare their performance experimentally on a set probability maps derived from aerial photographs.

This study aims to enhance the understanding about the influence of perceived ethical work climate dimensions on employees’ trust in co-workers. The instrument used was Victor and Cullen’s (1988) questionnaire containing five empirically derived types of ethical climate (caring, law and code, rules, instrumentalism, and independence). As hypothesized, the study revealed that the instrumental ethical climate dimension was negatively related, and independent climate was positively related to co-worker trust. Thus, two ethical climate dimensions (independent and instrumental) account for the 22.7 (...) percent variation taking place in co-worker trust while the remaining climate types had no significant impact. The findings may be of help particularly to human resource staff in developing policies to better off relations among employees acknowledging differing potential of ethical climate types. (shrink)

The theoretical and philosophical assumptions underlying our psychological practices greatly affect the ways that clinicians in the mental health field go about their work and to some extent how successful at it they are. This paper attempts to illustrate this by describing how a careful and systematic look at the underlying philosophical presuppositions surrounding the concept of transference yielded clear clinical benefits to my own practice of psychotherapy. More specifically, by contrasting the philosophical paradigm implied in the classical definitions of (...) transference with that of an alternative, phenomenologically-based model my understandings of the clinical phenomena in question were allowed to develop in new ways--ones which feel truer to the actual experiences in question and ultimately more helpful. 2012 APA, all rights reserved).

In this paper I present an interpretation of Deleuze's concept of the virtual. I argue that this concept is best understood in relation to the problematic of individuation or differentiation, which Deleuze inherits from Duns Scotus. After analysing Scotus' critique of Aristotelian or hylomorphic approaches to the problem of individuation, I turn to Deleuze's account of differentiation and his interpretation of the calculus in chapter 4 of Difference and Repetition. The paper seeks thereby to explicate Deleuze's dialectics or theory of (...) Ideas, his approach to the principle of sufficient reason, and the concept of the virtual itself. (shrink)

We are extremely grateful for the insightful and thought-provoking commentaries on our feature article. 1 We have distilled four themes emerging from the commentaries, and we would also like to address one misunderstanding of our argument that has appeared.

Climate protection is a societal issue, and we thank these authors for the concrete proposals of potential models to guide action.

Without wanting to put the main responsibility on them, we argue it is important to start thinking about the scope of action that... (shrink)

Downward causation exercised by emergent properties of wholes upon their lower-level constituents’ properties has been accused of conceptual and metaphysical incoherence. Only upward causation is usually peacefully accepted. The aim of this paper is to criticize and refuse the traditional hierarchical-vertical way of conceiving both types of causation, although preserving their deepest ontological significance, as well as the widespread acceptance of the traditional atomistic-combinatorial view of the entities and the relations that constitute the so-called ‘emergence base’. Assuming those two perspectives (...) with no reserves, we are condemned to confine our debate to the question of whether reified wholes can have the power to downwardly change or influence their lower-level parts, a question which seems profoundly misleading to me. I therefore propose an alternative relational ontological view, assuming a straightforward horizontal and intra-level way of representing those putative cases of cross-level causation. I finally confront two recent replies to Kim’s well-known objections to DC—Craver and Bechtel and Kistler :595–609, 2009)—, emphasizing their global positive approaches, as well as the reasons why their accounts still seem insufficient to me. I conclude arguing that both Kim’s principle of the causal closure of the physical domain and its allegation of an overdetermination in cases of DC can be surpassed by the new relational ontological perspective presented here.

In this article I address the issue of the ontological conditions of possibility for a naturalistic notion of emergence, trying to determine its fundamental differences from the atomist, vitalist, preformationist and potentialist alternatives. I will argue that a naturalistic notion of ontological emergence can only succeed if we explicitly refuse the atomistic fundamental ontological postulate that asserts that every entity is endowed with a set of absolutely intrinsic properties, being qualitatively immutable through its extrinsic relations. Furthermore, it will be shown (...) that, ironically enough, this metaphysical assumption is implicitly shared by all the above mentioned alternatives to Emergentism. The current article concludes that the notion of organization by itself is not enough, and that ontological emergence can only be justified by assuming a relational ontological perspective that, in opposition both to atomism and holism, defends that the existence-conditions, the identity and the causal behavior of any emergent systemic property can only be conceived, and explained, as constructed by and through specific networks of qualitatively transformative relational processes that occur between the system’s components and between the system and its environment. Additionally, I try to explain how one can make sense of the idea that an emergent phenomenon is both dependent on, and autonomous from, its emergence base. (shrink)

Feelings are conscious mental events that represent body states as they undergo homeostatic regulation. Feelings depend on the interoceptive nervous system (INS), a collection of peripheral and central pathways, nuclei and cortical regions which continuously sense chemical and anatomical changes in the organism. How such humoral and neural signals come to generate conscious mental states has been a major scientific question. The answer proposed here invokes (1) several distinctive and poorly known physiological features of the INS; and (2) a unique (...) interaction between the body (the ‘object’ of interoception) and the central nervous system (which generates the 'subject' of interoception). The atypical traits of the INS and the direct interactions between neural and non‐neural physiological compartments of the organism, neither of which is present in exteroceptive systems, plausibly explain the qualitative and subjective aspects of feelings, thus accounting for their conscious nature.

Physicians frequently encounter situations in which their professional practice is intermingled with moral affordances stemming from other domains of the physician’s lifeworld, such as family and friends, or from general morality pertaining to all humans. This article offers a typology of moral conflicts ‘at the margins of professionalism’ as well as a new theoretical framework for dealing with them. We start out by arguing that established theories of professional ethics do not offer sufficient guidance in situations where professional ethics overlaps (...) with moral duties of other origins. Therefore, we introduce the moral theory developed by Christine M. Korsgaard, that centres around the concept of practical identity. We show how Korsgaard’s account offers a framework for interpreting different types of moral conflicts ‘at the margins of professionalism’ to provide either orientation for solving the conflict or an explanation for the emotional and moral burden involved in moral dilemmas.

This study examines the challenges of humanism and education in the 21st century as addressed by the German philosopher Peter Sloterdijk in his Elmau Speech (1999). In this lecture, titled _Rules for the Human Zoo_, Sloterdijk argues that the traditional notion of humanism, specifically “humanism as a literary society,” has reached its conclusion, necessitating the development of a new humanism appropriate for the contemporary era. However, the new concept of humanism emerging from what Sloterdijk terms the “anthropotechnic turn” appears to (...) align with the discourses surrounding human enhancement that have emerged in the 21st century, thereby influencing the realm of education. The first half of this article reports on the significant concerns and criticisms expressed by the media at that time regarding this new humanism, which seems to be associated with eugenicist ideas. Taking a step further, this study critically examines the nature of the challenges around education implied by Sloterdijk, specifically the conflict between “friend of humans and friend of Übermensch”, and explores the potential roles and responsibilities of education in the latter part of the paper.

The global Covid-19 pandemic has resulted in social and economic disruption unprecedented in the modern era. Many countries have introduced severe measures to contain the virus, including travel restrictions, public event bans, non-essential business closures and remote work policies. While digital technologies help governments and organizations to enforce protection measures, such as contact tracing, their rushed deployment and adoption also raises profound concerns about surveillance, privacy and data protection. This article presents two critical cases on digital surveillance technologies implemented during (...) the Covid-19 pandemic and delineates the privacy implications thereof. We explain the contextual nature of privacy trade-offs during a pandemic and explore how regulatory and technical responses are needed to protect privacy in such circumstances. By providing a multi-disciplinary conversation on the value of privacy and data protection during a global pandemic, this article reflects on the implications digital solutions have for the future and raises the question of whether there is a way to have expedited privacy assessments that could anticipate and help mitigate adverse privacy implications these may have on society.

This essay offers a conception of logic by which logic may be considered to be exceptional among the sciences on the backdrop of a naturalistic outlook. The conception of logic focused on emphasises the traditional role of logic as a methodology for the sciences, which distinguishes it from other sciences that are not methodological. On the proposed conception, the methodological aims of logic drive its definitions and principles, rather than the description of scientific phenomena. The notion of a methodological discipline (...) is explained as a relation between disciplines or practices. Logic serves as a methodological discipline with respect to any theoretical practice, and this generality, as well as logic’s reflexive nature, distinguish it from other methodological disciplines. Finally, the evolution of model theory is taken as a case study, with a focus on its methodological role. Following recent work by John Baldwin and Juliette Kennedy, we look at model theory from its inception in the mid-twentieth century as a foundational endeavour until developments at the end of the century, where the classification of theories has taken centre-stage.

In this paper I discuss a prevailing view by which logical terms determine forms of sentences and arguments and therefore the logical validity of arguments. This view is common to those who hold that there is a principled distinction between logical and nonlogical terms and those holding relativistic accounts. I adopt the Tarskian tradition by which logical validity is determined by form, but reject the centrality of logical terms. I propose an alternative framework for logic where logical terms no longer (...) play a distinctive role. This account employs a new notion of semantic. (shrink)

One of the foundational problems of biochemistry concerns the conceptualisation of the relationship between the composition, structure and function of macromolecules like proteins. Part of the recent philosophical literature displays a reductionist bias, that is, the endorsement of a form of microstructuralism mirroring an out-dated biochemical conceptualisation. We shall argue that such microstructuralist approaches are ultimately committed to a potentialist form of micro-predeterminism whereby the macrostructure and function of proteins is accounted for solely in terms of the intrinsic properties and (...) potentialities of the components of the primary structure as if they were self-contained or essentially immutable entities. We shall instead suggest that a conceptualisation of the relationship between proteins’ composition, structure and function consistent with contemporary biochemical practice should account also for the causal role of the cellular, organismal and environmental relations in protein development. The analysis of the folding process we propose suggests that microstructure-laden reductionist approaches are ontologically indefensible. Rather than a potentialist form of micro-predeterminism, our analysis ultimately supports a relational-construction-based view of protein development and potentialities formation, which requires an indispensable analysis of the dynamical interplay between the micro-level of the parts and the macro-level of the relational structures of their systems.

To advance current knowledge on ethical decision-making in organizations, we integrate two perspectives that have thus far developed independently: the organizational identification perspective and the ethical climate perspective. We illustrate the interaction between these perspectives in two studies, in which we presented participants with moral business dilemmas. Specifically, we found that organizational identification increased moral decision-making only when the organization’s climate was perceived to be ethical. In addition, we disentangle this effect in Study 2 from participants’ moral identity. We argue (...) that the interactive influence of organizational identification and ethical climate, rather than the independent influence of either of these perspectives, is crucial for understanding moral decision-making in organizations.

Often institutions or individuals are faced with decisions where not all claims can be satisfied. Sometimes, these claims will be of differing strength. In such cases, it must be decided whether or not weaker claims can be aggregated in order to collectively defeat stronger claims. Many are attracted to a view, which this chapter calls Limited Aggregation, where this is sometimes acceptable and sometimes not. A new version of this view, Local Relevance, has recently emerged. This chapter seeks to explore (...) and evaluate this view. In order to do so, the chapter offers a more precise interpretation of this basic approach, calling it ‘Sequential Claims-Matching’. The chapter shows how Sequential Claims-Matching avoids problems that dog other Limited Aggregation views but suffers from difficulties and ambiguities of its own. In particular, the chapter shows that it is hard to accommodate some core Limited Aggregation intuitions around tie-break cases within the Local Relevance view. (shrink)

Tolerance is not, as is often thought, an attribute of urbanity that can be equated with other similar values, such as politeness. Nor is it - or at least it should not be - considered the oil that facilitates the smooth functioning of the engine of human desires, in spite of their differences of opinion. Rather, true tolerance takes root in the same soil as human rights. And this root is at the same time shared by liberty and truth. It (...) is an untamed, barely diplomatic, root, burrowing deep in the soil of an absolute demand. (shrink)

This paper proposes an integrated-structure notion of interlevel emergence, from a dynamic relational ontological perspective. First, I will argue that only the individualist essentialism of atomistic metaphysics can block the possibility of interlevel emergence. Then I will show that we can make sense of emergence by recognizing the formation of structures of transformative and interdependent causal relations in the generation and development of a particular class of mereological complexes called integrated systems. Finally, I shall argue that even though the emergent (...) structural attributes of such systems are not micro-determined nor micro-reducible, they can still be accounted for by an interlevel integrative neo-mechanistic form of explanation.

In a recent article, “Logical Consequence and Natural Language,” Michael Glanzberg claims that there is no relation of logical consequence in natural language (2015). The present paper counters that claim. I shall discuss Glanzberg’s arguments and show why they don’t hold. I further show how Glanzberg’s claims may be used to rather support the existence of logical consequence in natural language.

In this paper I argue that Vatter’s proposed solution to the problem of thanatopolitics in the development of a concept of eternal life is inadequate. In the first section I situate Vatter’s project, sketching out Foucault’s concept of biopolitics and marking Vatter’s specific difference from others working to articulate an affirmative biopolitics in contemporary discussions. In the second section I argue, following Foucault and Mbembe, that the possibility of a thanatopolitics or necropolitics that institutes regimes of mass death by racist (...) fragmentations of the population is a possibility intrinsic to biopolitics as such. In the third section I reconstruct Vatter’s proposal, according to which the thanatopolitical inversion can be blocked by developing an atheistic and philosophical concept of eternal life. I argue that this is inadequate for three reasons: first, the specifically contemplative character of the life Vatter proposes as eternal seems to valorize only a particular form of life; second, the transfinite character of living as such which is valorized in this conception seems to repeat, rather than repudiate, the logic of thanatopolitics; third, this concept of life as eternal seems not to be able to account for the reality of extinction.

Paraconsistent Weak Kleene logic is the 3-valued logic with two designated values defined through the weak Kleene tables. This paper is a first attempt to investigate PWK within the perspective and methods of abstract algebraic logic. We give a Hilbert-style system for PWK and prove a normal form theorem. We examine some algebraic structures for PWK, called involutive bisemilattices, showing that they are distributive as bisemilattices and that they form a variety, \, generated by the 3-element algebra WK; we also (...) prove that every involutive bisemilattice is representable as the Płonka sum over a direct system of Boolean algebras. We then study PWK from the viewpoint of AAL. We show that \ is not the equivalent algebraic semantics of any algebraisable logic and that PWK is neither protoalgebraic nor selfextensional, not assertional, but it is truth-equational. We fully characterise the deductive filters of PWK on members of \ and the reduced matrix models of PWK. Finally, we investigate PWK with the methods of second-order AAL—we describe the class \ of PWK-algebras, algebra reducts of basic full generalised matrix models of PWK, showing that they coincide with the quasivariety generated by WK—which differs from \—and explicitly providing a quasiequational basis for it.

Organ transplantation remains one of modern medicine's remarkable achievements. It saves lives, improves quality of life, diminishes healthcare expenditures in end-stage renal patients, and enjoys high success rates. Yet the promise of transplantation is substantially compromised by the scarcity of organs. The gap between the number of patients on waiting lists and the number of available organs continues to grow. As of January 2006, the combined waiting list for all organs in the United States was 90,284. Unfortunately, thousands of potential (...) organs are lost each year, primarily due to lack of consent to donation from the deceased before death, or from the family thereafter. Only fifty percent of potential donors – the “conversion” rate – become actual donors. The costs attributed to organ shortage are substantial – Medicare paid over $15.5 billion in 2002 for treating patients with end-stage renal-disease, who predominate on organ waiting lists. (shrink)

Las últimas décadas atestiguan un avance acelerado de la tecnología. El futuro que se augura es asombroso en múltiples sentidos. Camina a pasos agigantados y veloces.

In standard model-theoretic semantics, the meaning of logical terms is said to be fixed in the system while that of nonlogical terms remains variable. Much effort has been devoted to characterizing logical terms, those terms that should be fixed, but little has been said on their role in logical systems: on what fixing their meaning precisely amounts to. My proposal is that when a term is considered logical in model theory, what gets fixed is its intension rather than its extension. (...) I provide a rigorous way of spelling out this idea, and show that it leads to a graded account of logicality: the less structure a term requires in order for its intension to be fixed, the more logical it is. Finally, I focus on the class of terms that are invariant under isomorphisms, as they render themselves more easily to mathematical treatment. I propose a mathematical measure for the logicality of such terms based on their associated Löwenheim numbers. (shrink)

In this article I critically assess Deleuze’s interpretation of Spinoza’s metaphysics of modes. I argue that the conception of modal essence that Deleuze attributes to Spinoza is untenable in terms of Spinoza’s metaphysics.

I suggest that Deleuze’s interpretation of this crucial aspect of Spinozism runs the risk (...) of reinstating Platonic idealist and moralistic themes, of the kind that both Spinoza and Deleuze are committed to overcoming.
