This paper focuses on the extension of AGM that allows change for a belief base by a set of sentences instead of a single sentence. In [FH94], Fuhrmann and Hansson presented an axiomatic for Multiple Contraction and a construction based on the AGM Partial Meet Contraction. We propose for their model another way to construct functions: Multiple Kernel Contraction, that is a modification of Kernel Contraction, proposed by Hansson [Han94] to construct classical AGM contractions and belief base contractions. This construction (...) works out the unsolved problem pointed out by Hansson in [Han99, pp. 369]. (shrink)
In this work we consider a structured population with groups and subgroups of individuals. The intra-group dynamics is assumed to be fast in comparison with the inter-group dynamics. We study linear discrete models where the slow dynamics is represented by a single matrix and the fast dynamics is described by means of the first k terms of a converging sequence of different matrices. The number k can be interpreted as the ratio between the two time scales.The aim of this work (...) is to extend aggregation techniques to the case of fast changing environments. The main idea of aggregation is to build up a new system, with lower dimension, that summarizes the information concerning the fast process. This "aggregated" system provides essential information on the original one. It is shown that the asymptotic behavior of the original system can be approximated by the asymptotic behavior of the aggregated system when the ratio between the two time scales is large enough.

As the result of the complexity inherent in nature, mathematical models employed in ecology are often governed by a large number of variables. For instance, in the study of population dynamics we often deal with models for structured populations in which individuals are classified regarding their age, size, activity or location, and this structuring of the population leads to high dimensional systems. In many instances, the dynamics of the system is controlled by processes whose time scales are very different from (...) each other. Aggregation techniques take advantage of this situation to build a low dimensional reduced system from which behavior we can approximate the dynamics of the complex original system.In this work we extend aggregation techniques to the case of time dependent discrete population models with two time scales where both the fast and the slow processes are allowed to change at their own characteristic time scale, generalizing the results of previous studies. We propose a non-autonomous model with two time scales, construct an aggregated model and give relationship between the variables governing the original and the reduced systems. We also explore how the properties of strong and weak ergodicity, regarding the capacity of the system to forget initial conditions, of the original system can be studied in terms of the reduced system.

Esta obra está organizada en tres partes, en las que se indaga la plausibilidad del discurso de la Bioética y Teológica. En la primera de ellas, se estudia el vínculo que existe entre esta disciplina científica, el mensaje evangélico y la tradición cristiana, punto de partida y origen de todo este entramado bioético que aspira a sal-vaguardar valores humanos fundamentales. En la segunda, se trata de la relación que debe regir entre esta rama de la Teología y el polifacético mundo (...) científico (biomedicina, bioderecho, etc.). Por su parte, en la tercera, se analiza el estatuto epistemológico que configura a la Bioética Teológica, es decir, sus señas de identi-dad; asimismo, en esta sección, se indaga igualmente acerca del papel que, por derecho propio, corresponde en la vida pública a esta disciplina científica.

In this work we study the behavior of a time discrete multiregional stochastic model for a population structured in age classes and spread out in different spatial patches between which individuals can migrate. The dynamics of the population is controlled both by reproduction-survival and by migration. These processes take place at different time scales in the sense of the latter being much faster than the former. We incorporate the effect of demographic stochasticity into the population, which results in both dynamics (...) being modelled by multitype Bienaymé–Galton–Watson branching processes. We present a multitype global model that incorporates the effect of both processes and, making use of the existence of different time scales for demography and migration, build a reduced model in which the variables correspond to the total population in each age class. We extend previous results that relate the behavior of the original and the reduced model showing that, given a large enough separation of time scales between demography and migration, we can obtain information about the behavior of the multitype global model through the study of the simpler reduced model. We concentrate on the case where the two systems are supercritical and therefore the expected number of individuals grows to infinity, and show that we can approximate the asymptotic structure of the population vector and the asymptotic population size of the original system through the study of the reduced model.

As a result of the complexity inherent in some natural systems, mathematical models employed in ecology are often governed by a large number of variables. For instance, in the study of population dynamics we often find multiregional models for structured populations in which individuals are classified regarding their age and their spatial location. Dealing with such structured populations leads to high dimensional models. Moreover, in many instances the dynamics of the system is controlled by processes whose time scales are very (...) different from each other. For example, in multiregional models migration is often a fast process in comparison to the growth of the population.Approximate reduction techniques take advantage of the presence of different time scales in a system to introduce approximations that allow one to transform the original system into a simpler low dimensional system. In this way, the dynamics of the original system can be approximated in terms of that of the reduced system. This work deals with the study of that approximation. In particular, we work with a non-autonomous discrete time model previously presented in the literature and obtain different bounds for the error we incur when we describe the dynamics of the original system in terms of the reduced one. (shrink)
In this work we extend approximate aggregation methods in time discrete linear models to the case of time varying environments. Approximate aggregation consists in describing some features of the dynamics of a general system involving many coupled variables in terms of the dynamics of a reduced system with a few number of variables. We present a time discrete time varying model in which we distinguish two time scales. By using perturbation methods we transform the system to make the global variables (...) appear and build up the aggregated system. The asymptotic relationships between the general and aggregated systems are explored in the cases of a cyclically varying environment and a changing environment in process of stabilization. We show that under quite general conditions the knowledge of the behavior of the aggregated system characterizes that of the general system. The general method is also applied to aggregate a multiregional time dependent Leslie model showing that the aggregated model has demographic rates depending on the equilibrium proportions of individuals in the different patches.

En este trabajo me propongo desarrollar un estudio crítico de la concepción mecanicista de la explicación científica. En primer lugar, argumento que la caracterización mecanicista de los modelos fenoménicos (no explicativos) es inadecuada, pues no ofrece un análisis aceptable de los conceptos de modelo científico y similitud, que son fundamentales para la propuesta. En segundo lugar, sostengo que la caracterización de los modelos mecanicistas (explicativos) es igualmente inadecuada, pues los análisis disponibles de la relación explicativa de relevancia constitutiva implican una (...) tesis metafísica que es rechazada por los mismos mecanicistas. Concluyo que el mecanicismo no ofrece todavía una elucidación aceptable de la explicación científica. In this paper, I offer a critical assessment of the mechanicist approach to scientific explanation. Firstly, I argue that the mechanicist characterization of (non explanatory) phenomenological models is inadequate, since it does not develop an explication of the concepts of scientific model and similarity, which are indispensable to the approach. Secondly, I claim that the mechanicist conception of (explanatory) mechanicist models is inadequate as well, since all the available analices of the explanatory relation of constitutive relevance imply a metaphysical thesis that is rejected by the mechanicists themselves. I conclude that mechanicism needs to be emended if it aims to be considered as a genuinely illuminating approach to scientific explanation. (shrink)
My ultimate goal has always been to illuminate artistry at its greatest heights. Howard Gardner’s theory of multiple intelligences provided a theoretical framework for his life-long study of creativity, especially in prodigies like Picasso.1 According to Gardner, Picasso was weak in the scholastics and strong in the spatial, bodily, and personal spheres, characterizing the artist even as “frankly sadistic.”2 And Gardner developed a general framework for understanding the prodigy in terms of one’s proclivity toward meta-cognition as well as other commonalities (...) related to intrapersonal and interpersonal relations in various ways: childlike, few friends, one-minded, productivity, sacrifice, episodic ..

In World Poverty and Human Rights, Thomas Pogge argues that the global rich have a duty to eradicate severe poverty in the world. The novelty of Pogges approach is to present this demand as stemming from basic commands which are negative rather than positive in nature: the global rich have an obligation to eradicate the radical poverty of the global poor not because of a norm of beneficence asking them to help those in need when they can at little cost (...) to themselves, but because of their having violated a principle of justice not to unduly harm others by imposing on them a coercive global order that makes their access to the objects of their human right to subsistence insecure. In this paper, I claim that although Pogge is right in arguing that negative duties are crucial in an account of global justice, he is wrong in saying that they are the only ones that are crucial. Harming the global poor by causing their poverty provides a sufficient but not a necessary condition for the global rich to have a duty of justice to assist them. After engaging in a critical analysis of Pogges argument, I conclude by suggesting the need for a robust conception of cosmopolitan solidarity that includes positive duties of assistance which are not mere duties of charity, but enforceable ones of justice.

Are positive duties to help others in need mere informal duties of virtue or can they also be enforceable duties of justice? In this paper I defend the claim that some positive duties (which I call basic positive duties) can be duties of justice against one of the most important prin- cipled objections to it. This is the libertarian challenge, according to which only negative duties to avoid harming others can be duties of justice, whereas positive duties (basic or nonbasic) (...) must be seen, at best, as informal moral requirements or recommendations. I focus on the contractarian version of the libertarian challenge as recently presented by Jan Narveson. I claim that Narveson’s contractarian construal of libertarianism is not only intuitively weak, but is also subject to decisive internal problems. I argue, in particular, that it does not pro- vide a clear rationale for distinguishing between informal duties of virtue and enforceable duties of justice, that it can neither successfully justify libertarianism’s protection of negative rights nor its denial of positive ones, and that it fails to undermine the claim that basic positive duties are duties of global justice. -/- .

What should our theorizing about social justice aim at? Many political philosophers think that a crucial goal is to identify a perfectly just society. Amartya Sen disagrees. In The Idea of Justice, he argues that the proper goal of an inquiry about justice is to undertake comparative assessments of feasible social scenarios in order to identify reforms that involve justice-enhancement, or injustice-reduction, even if the results fall short of perfect justice. Sen calls this the “comparative approach” to the theory of (...) justice. He urges its adoption on the basis of a sustained critique of the former approach, which he calls “transcendental.” In this paper I pursue two tasks, one critical and the other constructive. First, I argue that Sen’s account of the contrast between the transcendental and the comparative approaches is not convincing, and second, I suggest what I take to be a broader and more plausible account of comparative assessments of justice. The core claim is that political philosophers should not shy away from the pursuit of ambitious theories of justice (including, for example, ideal theories of perfect justice), although they should engage in careful consideration of issues of political feasibility bearing on their practical implementation.

In his important new book National responsibility and global justice, David Miller presents a systematic challenge to existing theories of global justice. In particular, he argues that cosmopolitan egalitarianism must be rejected. Such views, Miller maintains, would place unacceptable burdens on the most productive political communities, undermine national self-determination, and disincentivize political communities from taking responsibility for their fate. They are also impracticable and quite unrealistic, at least under present conditions. Miller offers an alternative account that conceives global justice in (...) terms of a minimum set of basic rights that belong to human beings everywhere. Primary responsibility for securing such rights for an individual lies with his or her state, but in so far as these rights go unprotected, responsibilities for fulfilling them may fall on outsiders. While less ambitious that cosmopolitan egalitarian justice, Miller argues that his own view would nevertheless enable us to articulate what is most morally objectionable about our current world. In this article it is argued that none of Miller's critiques of cosmopolitan egalitarianism is effective, and that while certainly preferable to the status quo, a world governed by Miller's principles is not an attractive ideal.

To be justifiable, the demands of a conception of human rights and global justice must be such that (a) they focus on the protection of important human interests, and (b) their fulfilment is feasible. I discuss the feasibility condition. I present a general account of the relation between moral desirability, feasibility and obligation within a conception of justice. I analyse feasibility, a complex idea including different types, domains and degrees. It is possible to respond in various ways if the fulfilment (...) of basic socioeconomic human rights against severe poverty seems at first to be infeasible. (shrink)
Samuel Scheffler has recently argued that some relationships are non-instrumentally valuable; that such relationships give rise to “underived” special responsibilities; that there is a genuine tension between cosmopolitan egalitarianism and special responsibilities; and that we must consequently strike a balance between the two. We argue that there is no such tension and propose an alternative approach to the relation between cosmopolitan egalitarianism and special responsibilities. First, while some relationships are non-instrumentally valuable, no relationship is unconditionally valuable. Second, whether such relationships (...) give rise to special responsibilities is conditional on those relationships not violating certain moral constraints. Third, these moral constraints arise from within cosmopolitan egalitarianism itself. Thus the value of relationships and the special responsibilities to which they give rise arise within the parameters of cosmopolitan egalitarianism itself. The real tension is not between cosmopolitan equality and special responsibilities, but between special responsibilities and the various general duties that arise from the recognition, demanded by cosmopolitan egalitarianism, of a multiplicity of other basic goods. Indeed, even the recognition of special relationships itself gives rise to general duties that may condition and/or weigh against putative special responsibilities. (shrink)
This paper presents a reconstruction of and some constructive comments on Thomas Pogge’s conception of global justice. Using Imre Lakatos’s notion of a research program, the paper identifies Pogge’s “hard core” and “protective belt” claims regarding the scope of fundamental principles of justice, the object and structure of duties of global justice, the explanation of world poverty, and the appropriate reforms to the existing global order. The paper recommends some amendments to Pogge’s program in each of the four areas.

This paper is concerned with the claim that supervaluationist consequence is not classical for a language including an operator for definiteness. Although there is some sense in which this claim is uncontroversial, there is a sense in which the claim must be qualified. In particular I defend Keefe's position according to which supervaluationism is classical except when the inference from phi to Dphi is involved. The paper provides a precise content to this claim showing that we might provide complete (and (...) sound) systems of deduction for supervaluationist consequence in which proofs are completely classical with the exception of a single last step (involving the above mentioned inference).

This paper discusses Fara's so-called 'Paradox of Higher-Order Vagueness' concerning supervaluationism. In the paper I argue that supervaluationism is not committed to global validity, as it is largely assumed in the literature, but to a weaker notion of logical consequence I call 'regional validity'. Then I show that the supervaluationist might solve Fara's paradox making use of this weaker notion of logical consequence. The paper is discussed by Delia Fara in the same volume.
It is often assumed that the supervaluationist theory of vagueness is committed to a global notion of logical consequence, in contrast with the local notion characteristic of modal logics. There are, at least, two problems related to the global notion of consequence. First, it brings some counterexamples to classically valid patterns of inference. Second, it is subject to an objection related to higher-order vagueness . This paper explores a third notion of logical consequence, and discusses its adequacy for the supervaluationist (...) theory. The paper proceeds in two steps. In the first step, the paper provides a deductive notion of consequence for global validity using the tableaux method. In the second step, the paper provides a notion of logical consequence which is an alternative to global validity, and discusses i) whether it is acceptable to the supervaluationist and ii) whether it plays a better role in a theory of vagueness in the face of the problems related to the global notion.

Though it is standardly assumed that supervaluationism applied to vagueness is committed to global validity, Achille Varzi (2007) argues that the supervaluationist should take seriously the idea of adopting local validity instead. Varzi’s motivation for the adoption of local validity is largely based on two objections against the global notion: that it brings some counterexamples to classically valid rules of inference and that it is inconsistent with unrestricted higher-order vagueness. In this discussion I review these objections and point out ways (...) to address them not considered in Varzi’s paper. (shrink)
Paraconsistent approaches have received little attention in the literature on vagueness (at least compared to other proposals). The reason seems to be that many philosophers have found the idea that a contradiction might be true (or that a sentence and its negation might both be true) hard to swallow. Even advocates of paraconsistency on vagueness do not look very convinced when they consider this fact; since they seem to have spent more time arguing that paraconsistent theories are at least as (...) good as their paracomplete counterparts, than giving positive reasons to believe on a particular paraconsistent proposal. But it sometimes happens that the weakness of a theory turns out to be its mayor ally, and this is what (I claim) happens in a particular paraconsistent proposal known as subvaluationism. In order to make room for truth-value gluts subvaluationism needs to endorse a notion of logical consequence that is, in some sense, weaker than standard notions of consequence. But this weakness allows the subvaluationist theory to accommodate higher-order vagueness in a way that it is not available to other theories of vagueness (such as, for example, its paracomplete counterpart, supervaluationism).

Supervaluationism is a well known theory of vagueness. Subvaluationism is a less well known theory of vagueness. But these theories cannot be taken apart, for they are in a relation of duality that can be made precise. This paper provides an introduction to the subvaluationist theory of vagueness in connection to its dual, supervaluationism. A survey on the supervaluationist theory can be found in the Compass paper of Keefe (2008); our presentation of the theory in this paper will be short (...) to get rapidly into the logical issues. This paper is relatively self-contained. A modest background on propositional modal logic is, though not strictly necessary, advisable. The reader might find useful the Compass papers Kracht (2011) and Negri (2011) (though these papers cover issues of more complexity than what is demanded to follow this paper). (shrink)
It is a crucial question whether practicalities should have an impact in developing an applicable theory of human rights—and if, how (far) such constraints can be justified. In the course of the non-ideal turn of today’s political philosophy, any entitlements (and social entitlements in particular) stand under the proviso of practical feasibility. It would, after all, be unreasonable to demand something which is, under the given political and economic circumstances, unachievable. Thus, many theorist—particularly those belonging to the liberal camp—begin to (...) question the very idea of social human rights on grounds of practical infeasibility. This new minimalism about human rights motivates an immanent critique arguing that even if we were to proceed from a liberal framework, we would still wind up with a justification of the full list of social human rights. In the first part of this article, I will present the central positions of the debate presented by Amartya Sen, Maurice Cranston and Pablo Gilabert. Initially arguing that a minimalism of human rights on grounds of practical infeasibility alone proves unjustifiable, however, I shall open up two further perspectives, which allow practical infeasibilities to become normatively determinate. Discussing contributions by James Griffin and Charles Beitz, I will defend the thesis that certain feasibility constraints on (social) human rights can be justified on the condition that they are grounded either in a normative idea of the appropriate implementation of these rights or in reflection of the practical function of a theory of human rights.

Principles of procreative beneficence (PPBs) hold that parents have good reasons to select the child with the best life prospects. Sparrow (2010) claims that PPBs imply that we should select only female children, unlesswe attach normative significance to “normal” human capacities. We argue that this claim fails on both empirical and logical grounds. Empirically, Sparrow’s argument for greater female wellbeing rests on a selective reading of the evidence and the incorrect assumption that an advantage for females would persist even when (...) a serious gender imbalance is obtained. Logically, PPBs cite only pro tanto reasons and allow that the good of an individual child could be outweighed by other morally relevant considerations, such as those which take collectively suboptimal outcomes into account. There is thus no need to attach value to the “normal.”. (shrink)
This paper argues against the common practice of presenting perdurantism, endurantism, and other views about persistence and time as solutions to an alleged puzzle about change. Various recent attempts to generate a puzzle about change are examined and found unsuccessful. This does not mean, however, that the relevant views about persistence and time are not well motivated, but rather that their interest and purpose is independent of their suitability for solving the alleged puzzle.
In the contemporary debate about the nature of persistence, stage theory is the view that ordinary objects (artefacts, animals, persons, etc.) are instantaneous and persist by being suitably related to other instantaneous objects. In this paper I focus on the issue of what stage theorists should say about the semantics of ordinary proper names, like ‘Socrates’ or ‘London’. I consider the remarks that stage theorists actually make about this issue, present some problems they face, and finally offer what I take (...) to be the best alternative available for them.

In this paper we investigate a semantics for first-order logic originally proposed by R. van Rooij to account for the idea that vague predicates are tolerant, that is, for the principle that if x is P, then y should be P whenever y is similar enough to x. The semantics, which makes use of indifference relations to model similarity, rests on the interaction of three notions of truth: the classical notion, and two dual notions simultaneously defined in terms of it, (...) which we call tolerant truth and strict truth. We characterize the space of consequence relations definable in terms of those and discuss the kind of solution this gives to the sorites paradox. We discuss some applications of the framework to the pragmatics and psycholinguistics of vague predicates, in particular regarding judgments about borderline cases. (shrink)
The explanatory role of natural selection is one of the long-term debates in evolutionary biology. Nevertheless, the consensus has been slippery because conceptual confusions and the absence of a unified, formal causal model that integrates different explanatory scopes of natural selection. In this study we attempt to examine two questions: (i) What can the theory of natural selection explain? and (ii) Is there a causal or explanatory model that integrates all natural selection explananda? For the first question, we argue that (...) five explananda have been assigned to the theory of natural selection and that four of them may be actually considered explananda of natural selection. For the second question, we claim that a probabilistic conception of causality and the statistical relevance concept of explanation are both good models for understanding the explanatory role of natural selection. We review the biological and philosophical disputes about the explanatory role of natural selection and formalize some explananda in probabilistic terms using classical results from population genetics. Most of these explananda have been discussed in philosophical terms but some of them have been mixed up and confused. We analyze and set the limits of these problems. (shrink)
In this paper I criticize a version of supervaluation semantics. This version is called "Region-Valuation" semantics. It's developed by Pablo Cobreros. I argue that all supervaluationists, regionalists in particular, and truth-value gap theorists of vagueness more generally, are commited to the validity of D-intro, the principle that every sentence entails its definitization (the truth of "Paul is tall" guarantees the truth of "Paul is definitely tall"). The principle embroils one in a paradox that's distinct from, but related to, the (...) sorites paradox. I call it the "gap-principles paradox". -/- . (shrink)
In what follows I will consider Kant's and Habermas's conceptions of moral validity in a comparative and critical way. First, I will reconstruct Habermas's discursive or deliberative reformulation of Kant's moral theory (sec.1). And, second, I will introduce some comparative critical considerations (2). I will contend that, though much is gained with Habermas's intersubjectivist reformulation of Kant's moral philosophy, some problems emerge that could be treated with the help of certain Kantian insights. I will focus on Kant's and Habermas's strictly (...) moral writings. The issue of political validity or legitimacy (i.e., of the validity of norms that are to be enforced by a coercive state apparatus) is of course of great importance, but I will not address it here.

We present a reconstruction of so-called classical, formal or Mendelian genetics using a notation which we believe is more legible than that of earlier accounts, and lends itself easily to computer implementation, for instance in PROLOG. By drawing from, and emending, earlier work of Balzer and Dawe (1986,1997), the present account presents the three most important lines of development of classical genetics: the so-called Mendel's laws, linkage genetics and gene mapping, in the form of a theory-net. This shows that the (...) set theoretic representation format used in the structuralist approach to the philosophy of science also applies to the domain of genetic theories. There construction is intended to lend more clarity to theme thodological, philosophical and didactical discussions of the foundations of genetics, and on the other hand to defend a formally, logically minded view of theories which seems to have become contested through the work of Feyerabend, Kuhn and Kitcher.

The supervaluationist theory of vagueness is committed to a particular notion of logical consequence known as global validity. According to a recent objection, this notion of consequence is more problematic than is usually thought since i) it bears a commitment to some sort of bizarre inferences, ii) this commitment threatens the internal coherence of the theory and iii) we might find counterexamples to classically valid pat- terns of inference even in the absence of a definitely-operator (or similar device). As a (...) consequence, the supervaluationist theory itself is in trou- ble. This paper discusses the objection. (shrink)
Social scientific and humanistic research on synthetic biology has focused quite narrowly on questions of epistemology and ELSI. I suggest that to understand this discipline in its full scope, researchers must turn to the objects of the field—synthetic biological artifacts—and study them as the objects in the making of a science yet to be made. I consider one fundamentally important question: how should we understand the material products of synthetic biology? Practitioners in the field, employing a consistent technological optic in (...) the study and construction of biological systems, routinely employ the mantra ‘biology is technology’. I explore this categorization. By employing an established definition of technological artifects drawn from the philosophy of technology, I explore the appropriateness of attributing to synthetic biological artifacts the four criteria of materiality, intentional design, functionality, and normativity. I then explore a variety of accounts of natural kinds. I demonstrate that synthetic biological artifacts fit each kind imperfectly, and display a concomitant ontological ‘messiness’. I argue that this classificatory ambivalence is a product of the field’s own nascence, and posit that further work on kinds might help synthetic biology evaluate its existing commitments and practices.

The aim of this paper is to propose a model for understanding the relation between substance and procedure in discourse ethics and deliberative democracy capable of answering the common charge that they involve an ‘empty formalism’. The expressive-elaboration model introduced here answers this concern by arguing that the deliberative practical rationality presupposed by discourse ethics and deliberative democracy involves the creation of a practical medium in which certain general basic ideas of solidarity, equality and freedom are expressed and elaborated in (...) the context of widespread moral disagreement. In the course of this paper I propose an elucidation of these ideas and argue for the thesis that they are internally related to the endorsement of deliberative practical rationality. The three basic substantive ideas contribute to the determination of the existence, the form, the topics and intended outcomes, and the effects of the practice of public deliberation. This amounts to an elucidatory defense of deliberative practical rationality by explicating its substantive significance or point. Key Words: critical theory • deliberative democracy • discourse ethics • equality • freedom • Jürgen Habermas • practical reason • John Rawls • solidarity • substance and procedure. (shrink)
: This article focuses on one aspect of the late mediaeval debate over divine power, as it was discussed by Oxford philosophers Walter Chatton (d. 1343) and William Ockham (d. 1347). Chatton and Ockham would have agreed, for example, that God is ultimately responsible for the existence of the works of Pablo Picasso, but they would not agree over wheher it violates God's omnipotence to say that he cannot make something that Picasso made, for example, the painting Guernica, without (...) using Picasso himself as an intermediate cause. The context of their dispute was a larger debate regarding the ontological status of relations. This article (1) explains how these two issues, omnipotence and relations, became so interestingly tangled together, (2) tries to see which of the two men mentioned above got the better of their exchange, and finally (3) draws out some important consequences for fourteenth-century discussions of causality, occasionalism, and omnipotence.

This paper presents a substantivist construal of discourse ethics, which claims that we should see our engagement in public deliberation as expressing and elaborating a substantive commitment to basic moral ideas of solidarity, equality, and freedom. This view is different from Habermas's standard formalist defence of discourse ethics, which attempts to derive the principle of discursive moral justification from primarily non-moral presuppositions of rational argumentation as such. After explicating the difference between the substantivist and the formalist construal, I (...) defend the former by showing that it is not only intuitively compelling, but also particularly well equipped for addressing four important objections recently levelled against discourse ethics and its political applications (Rawls's concern that it lacks substantive guidelines, Gunnarsson's challenge that it has not been proven to be superior to alternative moral conceptions such as utilitarianism, Scanlon's complaint that it lacks an account of moral motivation, and Galston's and Young's worries that it could lead to political practices of cultural imposition). I conclude by pointing out some consequences of the previous discussion for the future of Critical Theory. (shrink)
The ‘paradoxes of coincidence’ are generally taken as an important factor for deciding between rival views on persistence through time. In particular, the ability to deal with apparent cases of temporary coincidence is usually regarded as a good reason for favouring perdurantism (or ‘four-dimensionalism’) over endurantism (or ‘three-dimensionalism’). However, the recent work of Gilmore ( 2007 ) and McGrath ( 2007 ) challenges this standard view. For different reasons, both Gilmore and McGrath conclude that perdurantism does not really obtain support (...) from the puzzles of temporary coincidence. In this paper, I will evaluate their arguments and defend the opposite view: that the paradoxes of coincidence do give some support to perdurantism. However, the way in which they do so is rather unexpected. As we will see, there are different ways in which coincidence scenarios may be thought to support perdurantism, some of which have not yet been sufficiently explored. Thus, my immediate goal is to explore one of those directions, bringing into focus a new argument from coincidence to perdurantism. And although I motivate my discussion by examining the arguments in the work of Gilmore and McGrath, the merits of this argument can be independently assessed. More generally, my overall purpose is to contribute to our general understanding of how the topics of coincidence and persistence bear on each other. (shrink)
We perform an experimental investigation using a dictator game in which individuals must make a moral decision —to give or not to give an amount of money to poor people in the Third World. A questionnaire in which the subjects are asked about the reasons for their decision shows that, at least in this case, moral motivations carry a heavy weight in the decision: the majority of dictators give the money for reasons of a consequentialist nature. Based on the results (...) presented here and of other analogous experiments, we conclude that dicator behavior can be understood in terms of moral distance rather than social distance and that it systematically deviates from the egoism assumption in economic models and game theory.

In recent years, there has been a growing interest in Kant's doctrine of radical evil, arising from as diverse quarters as philosophy, psychoanalysis and the social sciences. This interest has contributed to the revival of the notion of evil, which had been displaced from the center of philosophical discussion in the 20th century. A common trait in the recent literature is that it takes the relevance of the use of the concept of evil for granted. Yet, before understanding what Kant (...) really means by radical evil, it seems appropriate to ask first whether the notion of evil as such is necessary. For, given its religious background, this notion elicits expectations that may be incompatible with the secular concerns of moral philosophy. Such misgivings are aggravated by additional doubts about the concept's explanatory function in the first place. The pertinence of reviving a concept so allegedly flawed cannot be taken at face value. Thus, the task I set for myself here is to show the necessity of the concept of evil as it lies at the core of Kant's moral philosophy already in the Groundwork, far before he actually coins the notion of “radical evil” in the Religion. Whether this latter account is defensible or not, we will at least be sure that talk about an evil which is said to be radical is not in vain. (shrink)
This is the first comprehensive reference to the vast field of world philosophy. The Dictionary covers all the major subfields of the discipline, with entries drawn from West African, Arabic, Chinese, Indian, Japanese, Jewish, Korean, Latin American, Maori, and Native American philosophy--including Nahua philosophy, a previously unexplored, but key instance of Pre-Hispanic thought. Entries include: * abazimu * abortion * Advaita * afrocentricity * age of the world * artificial life * baskets of knowledge * bhakti body *brotherhood * chain (...) of being * Chinese legalism * creation *cybernetics * darshana * death * dravya * euthanasia *love * madrash * memory * Mohism * paradox * passion* philosophy of education * speculative grammar * paranormal *Aouism * theurgy * truth * virtue * Zen * and many more.

In this paper we investigate a semantics for first-order logic originally proposed by R. van Rooij to account for the idea that vague predicates are tolerant, that is, for the principle that if x is P , then y should be P whenever y is similar enough to x. The semantics, which makes use of indifference relations to model similarity, rests on the interaction of three notions of truth: the classical notion, and two dual notions simultaneously defined in terms of (...) it, which we call tolerant truth and strict truth. We characterize the space of consequence relations definable in terms of those and discuss the kind of solution this gives to the sorites paradox. We discuss some applications of the framework to the pragmatics and psycholinguistics of vague predicates, in particular regarding judgments about borderline cases. (shrink)
This paper examines employees’ reactions to Corporate Social Responsibility (CSR) programs at the attitudinal level. The results presented are drawn from an in-depth study of two Chilean construction firms that have well-established CSR programs. Grounded theory was applied to the data prior to the construction of the conceptual framework. The analysis shows that the implementation of CSR programs generates two types of attitudes in employees: attitudes toward the organization and attitudes toward society. These two broad types of attitudes can then (...) be broken down into four different categories: (1) acceptance of the new role of the organization, (2) identification with the organization, (3) importance attached to the work performed and (4) a sense of social justice. In turn, each of these categories is a grouping of many different concepts, some of which have at first sight little to do with CSR. Finally, the analysis reveals an attitudinal employee typology: the committed worker, the indifferent worker, and the dissident worker. (shrink)
A transparent truth predicate T is one that, paired with some quotation device , allows, for any wff A, for the claim T A to be substituted for A or vice versa, in all extensional contexts in all arguments without change in validity. This paper presents and defends a way to add a transparent truth predicate to classical logic, a way that builds on our earlier work on vagueness in [Cobreros et al., 2011b, Cobreros et al., 2011a]. A number of (...) other authors have sought a transparent truth predicate, and reached it by weakening classical logic in various ways. The key advantage of our approach, from which a number of other advantages will follow, lies in its keeping to classical logic. (shrink)
In this paper, I argue that both perdurance theory and the ‘relations-to-times’ endurantist view rely on an atemporal notion of property instantiation and relation bearing. I distinguish two possible meanings of ‘atemporal’ which result in two different understandings of what it is for an object to have a property or to bear a relation atemporally. I show that standard presentations of the theories considered are indeterminate as to which of these two understandings is the intended one. I claim that even (...) if both understandings are admissible, one of them is more attractive and has more to recommend than the other. (shrink)
This commentary explores the use of interaction between moral heuristics and emotional intelligence (EI). The main insight presented is that the quality of moral decisions is very sensitive to emotions, and hence this may lead us to a better understanding of the role of emotional abilities in moral choices. In doing so, we consider how individual differences (specifically, EI) are related to moral decisions. We summarize evidence bearing on some of the ways in which EI might moderate framing effects in (...) different moral tasks such as “the Asian disease problem” and other more real-life problems like “a divorce decision.”.

In this article, we present the case for regarding the principles by which scholarly publications are disseminated and shared as a matter of academic ethics. The ethics of access have to do with recognizing people's right to know what is known, as well as the value to humanity of having one of its best forms of arriving at knowledge as widely shared as possible. The level of access is often reduced by the financial interests of publishers in a market in (...) which there is little sense of a rational order, given huge discrepancies in prices for similar products. At the same time, there are risks to limiting researchers? access to scholarly resources, both for the quality of the knowledge that is not entirely open to review and for the production of new knowledge that it might inspire. Then, there are issues of access beyond the academy for professional practice and out of human interest, for both of which undue limitations raise what are, for us, more than academic ethical questions.

Synthetic biology, an emerging field of science and technology, intends to make of the natural world a substrate for engineering practice. Drawing inspiration from conventional engineering disciplines, practitioners of synthetic biology hope to make biological systems standardized, calculable, modular, and predictably functional. This essay develops a Heideggerian reading of synthetic biology as a useful perspective with which to identify and explore key facets of this field, its knowledge, its practices, and its products. After overviews of synthetic biology and Heidegger’s account (...) of technology, I discuss calculability, utility, function, setting-upon, and ordering, with the aim of discussing the manner in which synthetic biology works to render the biological world intelligible as something to be used, rather than something that is in and of itself. Having developed this Heideggerian reading, I proffer a number of corrections to his account that enable a more accurate, nuanced understanding of synthetic biology. Specifically, I discuss the notion of Ge-stell and submit that multiple systems of “enframing” may help to make Heidegger’s argument more robust. I suggest that synthetic biology may work to reveal the natural world as a standing-reserve of function. (shrink)
From its dissonant musics to its surrealist spectacles (the urinal is a violin!), Modernist art often seems to give more frustration than pleasure to its audience. In Untwisting the Serpent, Daniel Albright shows that this perception arises partly because we usually consider each art form in isolation, even though many of the most important artistic experiments of the Modernists were collaborations involving several media--Igor Stravinsky's The Rite of Spring is a ballet, Gertrude Stein's Four Saints in Three Acts is an (...) opera, and Pablo Picasso turned his cubist paintings into costumes for Parade. Focusing on collaborations with a musical component, Albright views these works as either figures of dissonance that try to retain the distinctness of their various media (e.g. Guillaume Apollinaire's Les Mamelles de Tiresias ) or figures of consonance that try to lose themselves in some total effect (e.g. Arnold Schoenberg's Erwartung ). In so doing he offers a fresh picture of Modernism, and provides a compelling model for the analysis of all artistic collaborations. Untwisting the Serpent is the recipient of the 2001 Susanne M. Glasscock Humanities Book Prize for Interdisciplinary Scholarship of the Center for Humanities Research at Texas A&M University. (shrink)
Spain is one of the most advanced European countries in terms of the legislative and administrative development of ADs. Article 11 of Law 41/2002, concerning Patient Autonomy, regulates 'advance directives' and has prompted various Autonomous Regions to develop legislation in this area. Nevertheless, whilst the variety of legislations in different territories presents advantages, the disparity of criteria also presents problems. Despite significant legislative development, only 23,000 Spanish citizens have filled in an AD. Clearly, AD use is confined to a minority. (...) Several surveys, however, show that the Spanish population views these documents in a positive light. Thus, we must analyse this discrepancy between attitude and practice. A similar situation exists amongst health professionals. Whilst they generally feel that the use of ADs is positive and necessary, they are frequently unwilling to employ them. Bioethical literature and research on ADs has significantly increased in Spain over the last six years. It is likely that this trend will continue in the foreseeable future; but more resources and effort are required if ADs are to become consolidated. (shrink)
The purpose of this study was to extend the knowledge about why procedural justice (PJ) has behavioral implications within organizations. Since prior studies show that PJ leads to legitimacy, the author suggests that, when formal regulations are unfairly implemented, they lose their validity or efficacy (becoming deactivated even if they are formally still in force). This “rule deactivation,” in turn, leads to two proposed destructive work behaviors, namely, workplace deviance and decreased citizenship behaviors (OCBs). The results support this mediating role (...) of RD, thus suggesting that it forms part of the generative mechanism through which unfair procedures influence (un)ethical behavior within organizations. The author ends the article by discussing behavioral ethics and managerial implications as well as suggestions for future research. (shrink)

This landmark work will make a genuine contribution to the theory and practice of reparations.
In this article, we shed light on the debate about the financial performance of socially responsible investment (SRI) mutual funds by separately analyzing the contributions of before-fee performance and fees to SRI funds’ performance, and by investigating the role played by fund management companies in the determination of those variables. We apply the matching estimator methodology to obtain our results and find that in the period 1997–2005, US SRI funds had better before- and after-fee performance than conventional funds with similar (...) characteristics. The differences, however, are driven exclusively by SRI funds run by management companies specialized in SRI. While these funds significantly outperform similar conventional funds, funds run by companies not specialized in SRI underperform their matched conventional funds. We find no significant differences in fees between SRI and conventional funds except in one case: SRI funds are cheaper than conventional funds run by the same management company. (shrink)
