Physical and mental training are associated with positive effects on executive functions throughout the lifespan. However, evidence of the benefits of combined physical and mental regimes over a sedentary lifestyle remain sparse. The goal of this study was to investigate potential mechanisms, from a source-resolved event-related-potential perspective, that could explain how practicing long-term physical and mental exercise can benefit neural processing during the execution of an attention switching task. Fifty-three healthy community volunteers who self-reported long-term practice of Tai Chi, meditation (...) + exercise, simple aerobics, or a sedentary lifestyle, aged 47.8 ± 14.6 were included in this analysis. All participants undertook high-density electroencephalography recording during a switch paradigm. Our results indicate that people who practice physical and mental exercise perform better in a task-switching paradigm. Our analysis revealed an additive effect of the combined practice of physical and mental exercise over physical exercise only. In addition, we confirmed the participation of frontal, parietal and cingulate areas as generators of event-related-potential components commonly associated to the performance of switch tasks. Particularly, the N2-like component of the parietal and frontal domains showed significantly greater amplitudes in the exercise and mental training groups compared with aerobics and sedentary groups. Furthermore, we showed better performance associated with greater N2-like amplitudes. Our multivariate analysis revealed that activity type was the most relevant factor to explain the difference between groups, with an important influence of age, and body mass index, and with small effects of educational years, cardiovascular capacity, and sex. These results suggest that chronic combined physical and mental training may confer significant benefits to executive function in normally aging adults, probably through more efficient early attentional processing. Future experimental studies are needed to confirm our results and understand the mechanisms on parieto-frontal networks that contribute to the cognitive improvement associated with practicing combined mental and aerobic exercise, while carefully controlling confounding factors, such as age and body mass index.

Substructural approaches to paradoxes have attracted much attention from the philosophical community in the last decade. In this paper we focus on two substructural logics, named ST and TS, along with two structural cousins, LP and K3. It is well known that LP and K3 are duals in the sense that an inference is valid in one logic just in case the contrapositive is valid in the other logic. As a consequence of this duality, theories based on either logic are (...) tightly connected since many of the arguments for and objections against one theory reappear in the other theory in dual form. The target of the paper is making explicit in exactly what way, if any, ST and TS are dual to one another. The connection will allow us to gain a more fine-grained understanding of these logics and of the theories based on them. In particular, we will obtain new insights on two questions concerning ST which are being intensively discussed in the current literature: whether ST preserves classical logic and whether it is LP in sheep’s clothing. Explaining in what way ST and TS are duals requires comparing these logics at a metainferential level. We provide to this end a uniform proof theory to decide on valid metainferences for each of the four logics. This proof procedure allows us to show in a very simple way how different properties of inferences (unsatisfiability, supersatisfiability and antivalidity) that behave in very different ways for each logic can be captured in terms of the validity of a metainference.

The Purpose in Life Test is a measure of purpose in life widely used in many cultures and countries; however, cross-cultural assessments are scarce. The present study aimed to evaluate the cross-cultural measurement invariance of the PIL in the general population of seven Latin American countries. A total of 4306 people participated, selected by non-probabilistic convenience sampling, where Uruguay has the highest mean age ; while Ecuador has the lowest mean age. Furthermore, in each country, there is a higher proportion (...) of women than men. Using Multi-Group Confirmatory Factor Analysis, the factorial structure does not show evidence of invariance among the included countries. However, based on the Multi-Group Factor Analysis Alignment, there is evidence that a three-dimensional structure of the PIL is the same in the participating countries. Results based on item response theory indicate that most PIL items can significantly differentiate responses according to the level of life purpose. In addition, people with low life purpose will tend to choose the lower response alternatives on the PIL; while people with higher life purpose will choose higher response alternatives. The findings indicate that the PIL has the potential to increase knowledge about how people conceive and experience their purpose in life in different countries. (shrink)

According to a popular narrative, in 1932 von Neumann introduced a theorem that intended to be a proof of the impossibility of hidden variables in quantum mechanics. However, the narrative goes, Bell later spotted a flaw that allegedly shows its irrelevance. Bell’s widely accepted criticism has been challenged by Bub and Dieks: they claim that the proof shows that viable hidden variables theories cannot be theories in Hilbert space. Bub’s and Dieks’ reassessment has been in turn challenged by Mermin and (...) Schack. Hereby I critically assess their reply, with the aim of bringing further clarification concerning the meaning, scope and relevance of von Neumann’s theorem. I show that despite Mermin and Schack’s response, Bub’s and Dieks’ reassessment is quite correct, and that this reading gets strongly reinforced when we carefully consider the connection between von Neumann’s proof and Gleason’s theorem.

Juan Manuel Burgos presents his own version of personalism, which is nevertheless well rooted in the personalist tradition. He has been developing his project for years and is among a group of world-renowned personalists who study the complexity and mystery of the human person. His new book deals with the relationship between personalism and metaphysics. He poses the question of whether personalism can be considered a first philosophy. The answer is positive: it is indeed a sectorial first philosophy, which (...) may or may not be supported by traditional metaphysical projects, especially Thomistic ones. Not every personalist has to agree with its final thesis, although its position is well-founded and deserves much scholarly attention. It provokes further questions and opens up new areas of personalist discussion. This book confirms that personalism is a dynamic and growing school of thought that goes beyond describing the mere phenomena of the person and seeks deeper reasons for his being. I highly recommend this book as a new step to help us better understand the reality of the human person. (shrink)

In this paper I argue that the case of Einstein׳s special relativity vs. Hendrik Lorentz׳s ether theory can be decided in terms of empirical evidence, in spite of the predictive equivalence between the theories. In the historical and philosophical literature this case has been typically addressed focusing on non-empirical features. I claim that non-empirical features are not enough to provide a fully objective and uniquely determined choice in instances of empirical equivalence. However, I argue that if we consider arguments proposed (...) by Richard Boyd, and by Larry Laudan and Jarret Leplin, a choice based on non-entailed empirical evidence favoring Einstein׳s theory can be made.

As physicians encounter an increasingly diverse patient population, socioeconomic circumstances, religious values and cultural practices may present barriers to the delivery of quality care. Increasing cultural competence is often cited as a way to reduce healthcare disparities arising from value and cultural differences between patients and providers. Cultural competence entails not only a knowledge base of cultural practices of disparate patient populations, but also an attitude of adapting one's practice style to meet patient needs and values. Gender roles, relationship dynamics (...) and boundaries are culture specific, and are frequently shaped by religious teachings. Consequently, religion may be conceptualised as a cultural repertoire, or dynamic tool-kit, by which members of a faith adapt and negotiate their identity in multicultural societies. The manner in which Islamic beliefs and values inform Muslim healthcare behaviours is relatively under-investigated. In an effort to explore the impact of Islam on the relationship between patients and providers, we present an Islamic bioethical perspective on cross-gender relations in the patient-doctor relationship. We will begin with a clinical scenario highlighting three areas of gender interaction that bear clinical relevance: dress code, seclusion of members of the opposite sex and physical contact. Next, we provide a brief overview of the foundations of Islamic law and ethical deliberation and then proceed to develop ethicolegal guidelines pertaining to gender relations within the medical context. At the end of this reflection, we offer some practice recommendations that are attuned to the cultural sensitivities of Muslim patient populations. (shrink)

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.

It is a widespread belief that the Kochen-Specker theorem imposes a contextuality constraint on the ontology of beables in quantum hidden variables theories. On the other hand, after Bell’s influential critique, the importance of von Neumann’s wrongly called ‘impossibility proof’ has been severely questioned. However, Max Jammer, Jeffrey Bub and Dennis Dieks have proposed insightful reassessments of von Neumann’s theorem: what it really shows is that hidden variables theories cannot represent their beables by means of Hermitian operators in Hilbert space. (...) Hereby I show that i) the very same constraint can be derived from Gleason’s theorem, and that ii) if we consider the import of von Neumann’s and Gleason’s theorems, the relevance of the Kochen-Specker theorem for hidden variables theories gets substantially weakened: it does not force them to be contextual in any interesting sense of the term.

In this paper I analyze three artificial examples of empirical equivalence: van Fraassen’s alternative formulations of Newton’s theory, the Poincaré-Reichenbach argument for the conventionality of geometry; and predictively equivalent ‘systems of the world’. These examples have received attention in the philosophy of science literature because they are supposed to illustrate the connection between predictive equivalence and underdetermination of theory choice. I conclude that this view is wrong. These examples of empirical equivalence are harmless with respect to the problem of underdetermination.

I consider the question of why Latin American refugees often fail to transmit understanding of the strength of the moral demand on US agents, legislators and administrators to provide them with refuge in the US. To answer this question, I present two forms of hermeneutical injustice that are novel with respect to the epistemic injustice literature. These forms of hermeneutical injustice are what I call misleading resource injustice and psychological commitment injustice. I submit that these two kinds of hermeneutical injustice (...) put into view a dual remedy that involves, on the one hand, diversifying news organizations that populate the social imaginary with interpretative resources and, on the other hand, promoting the number of non-dominant group-controlled news organizations.

In this paper, I develop a quasi-transcendental argument to justify Kant’s infamous claim “man is evil by nature.” The cornerstone of my reconstruction lies in drawing a systematic distinction between the seemingly identical concepts of “evil disposition” (böseGesinnung) and “propensity to evil” (Hang zumBösen). The former, I argue, Kant reserves to describe the fundamental moral outlook of a single individual; the latter, the moral orientation of the whole species. Moreover, the appellative “evil” ranges over two different types of moral failure: (...) while an “evil disposition” is a failure to realize the good (i.e., to adopt the motive of duty as limiting condition for all one’s desires), an “evil propensity” is a failure to realize the highest good (i.e., to engage in the collective project of transforming the legal order into an ethical community). This correlation between units of moral analysis and types of obligation suggests a way to offer a deduction of the universal propensity on behalf of Kant. It consists in tracing the source of radical evil to the same subjective necessity that gives rise to the doctrine of the highest good. For, at the basis of Kant’s two doctrines lies the same natural dialectic between happiness and morality. While the highest good brings about the critically acceptable resolution of this dialectic, the propensity to evil perpetuates and aggravates it. Instead of connecting happiness and morality in an objective relation, the human will subordinatesmorality to the pursuit of happiness according to the subjective order of association. If this reading is correct, it would explain why prior attempts at a transcendental deduction have failed: interpreters have looked for the key to the deduction in the body of Kant’s text, where it is not to be found, for it is tucked, instead, in the Preface to the first edition.

Édouard Le Roy as early as 1901 observed the existence of an intellectual movement seeking to break from traditional positivism and set for himself the task of drawing up the program of this new positivism. Noting that this program precedes the Vienna Circle, I endeavor to determine its nature and to evaluate its impact on logical positivism. Viewed in this light, the discussions between Le Roy, Poincaré and Duhem appear more prolonged and substantial than is usually thought. What we have (...) here is perhaps not a homogeneous doctrine but a vigorous intellectual movement, from which logical positivists were able to borrow specific theses in their attempts to mitigate Mach's strict positivism; more important still, they had before them an example of neopositivism. History is not the only concern: among the issues debated, one encounters the claim that facts are theory-laden. This claim still stirs controversy today. An inquiry into the origins of the claim is one way of clarifying the arguments involved. (shrink)

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)

Truthmaking without truthmakers (TWT, for short) is the thesis that although every true proposition is made true by reality, there need not be particular entities (like facts, states of affairs, or tropes) that make these propositions true. The first substantial part of this paper (section 2) is devoted to developing a particular version of TWT and at the same time defending TWT in general from arguments against it that have been advanced by orthodox truthmaker theorists. In the second part of (...) the paper (section 3) I argue that talk about truthmakers within the theory can be understood as metaphoric and as conveying valuable information about something other than the supposed truthmakers: about truthmaking. The aim of this paper is therefore twofold. On the one hand, I intend to present the view on truthmaking, a version of TWT, that I find most plausible in the light of the arguments for and against truthmaker theory. On the other hand, I argue that friends of TWT have good reason to adopt a figuralist approach to truthmaker theory, rather than rejecting it outright. (shrink)

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.

This essay examines the relationship between African American internal colonialism and democracy, highlighting the complexities of democracy that make it both susceptible to oppressive violence at home and abroad, as well as a potential resource for emancipation and equality. I understand “internal colonialism” here to encompass various terms used by African Americans beginning in the 1830s, including semi-colonialism, domestic colonialism, and a nation within a nation. Much political philosophy assumes that society is “nearly just” or “generally just,” or that oppression (...) and injustice are found in societies that we nonetheless deem legitimate. Centering the complexities and possibilities of democracy instead shifts the focus to how democracy is compatible with violence and injustice, as well as their overcoming. Such a focus leads to a consideration of abolition democracy and the question of what the process of overcoming internal colonialism demands. (shrink)

A salient feature of de Broglie-Bohm quantum theory is that particles have determinate positions at all times and in all physical contexts. Hence, the trajectory of a particle is a well-defined concept. One then may expect that the closely related notion of inertial trajectory is also unproblematically defined. I show that this expectation is not met. I provide a framework that deploys six different ways in which dBB theory can be interpreted, and I state that only in the canonical interpretation (...) the concept of inertial trajectory is the customary one. However, in this interpretation the description of the dynamical interaction between the pilot-wave and the particles, which is crucial to distinguish inertial from non-inertial trajectories, is affected by serious difficulties, so other readings of the theory intend to avoid them. I show that in the alternative interpretations the concept at issue gets either drastically altered, or plainly undefined. I also spell out further conceptual difficulties that are associated to the redefinitions of inertial trajectories, or to the absence of the concept. (shrink)

The objective of this paper is to reflect on the proper way for Christians to do philosophy, in respect of which I have been inspired by a phrase attributed to Cardinal Newman: “We do not need Christian philosophy. We need Christians making good philosophy.” This sentence can appear controversial, but I believe it is not, if its content is made explicit in an appropriate way. To better develop what I understand Newman to be proposing here, I have added another category (...) to his statement, with the consequence that my own text falls into three sections: 1) on Christian philosophy; 2) on Christian philosophers; 3) on Christians who do philosophy. This is the scheme that we will use to position ourselves as regards the complex issue of the relationship between philosophy and Christianity. (shrink)

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)

One of the most intriguing bio-objects in the emerging field of regenerative medicine is umbilical cord blood. Employed in existing haematological therapies, but also loaded with potentialities for future uses, cord blood has been lately the focus of a regulatory debate which confronts public and private forms of biobanking. This article explores the political and anthropological side of this debate, describing the ways in which different health practices related to the umbilical cord (and to its symbolic sibling, the placenta) have (...) been involved in processes of societal production and reproduction. Through the use of ethnological and historical data, and their comparison with current practices, I contend that the technical manipulation of cords and placentas goes much longer into the past than what a first glance suggests, and that these two objects can be understood as biological spaces in which forms of social belonging and versions of the societal bond are at play. The current conflict between public and private cord blood banks is therefore interpreted as part of a longer history of bodily practices, and as reflecting recent mutations in the biopolitical constitution of advanced liberal societies.

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.

Philosophical personalism has generated a very powerful field of study in the twentieth and twenty first centuries but has not produced a systematic exposition. This book fills this big gap by offering for the first time a full systematic personalistic vision of the human person. This ambitious volume offers a pedagogical and integrated exposition of philosophical personalism, answering vital questions about human identity and existence in a way that the reader can achieve an integrated view of the person. The book (...) points to the real life of each person so that, by partially unraveling the mystery of the personal being, it becomes a philosophical guide for life. For these reasons, the book can be used both for academic purposes, as a manual of philosophy of man or for personal enlightenment. Divided in five parts, the first part of the book works as an introduction, offering an overview of the human person and of the notion of person. The second part describes the internal structure of the human being addressing topics as corporeity as a personal fact; sensibility and the senses; affectivity; intelligence; freedom understood as choice and self-determination and, finally, the personal self. The third part analyses the person in action and some special types of action such as work and language. The fourth part deals with interpersonal relationships beginning with I-You relationship and following with the family and the social structure. Finally, part five deals with the so-called ultimate questions, that is, those that decide the final meaning of each person's life, namely, time, death, immortality, and religion. (shrink)

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)

ABSTRACT: Kant and Mendelssohn published almost simultaneously influential essays on the Enlightenment. I use this historical contingency as occasion to reflect on the presuppositions and implications their views have with respect to philosophy and politics. In the first part, I compare Mendelssohn's discursive strategy with that of traditional liberalism. A contradiction emerges from this contrast, which, in the second part, I interpret in Kantian terms as an antinomy of modern political reason. Kant's notion of “autonomy,” I suggest, is an attempt (...) to overcome this very antinomy. Putting things this way allows us to better appreciate the originality of Kant's defense of the free use of public reason and his contribution to the liberal tradition. (shrink)

After discussing the transformation of age-old agricultural practices that has been occurring since the mid nineteenth century, and its impact on the natural environment, I identify four features of technology that point to the ambiguity of the idea of "technological progress". These are linked to the intrinsic unpredictability of technological applications and have implications for evaluating technological risks. I then show that large scale technological applications and innovations - such as expanding the practice of smallpox inoculation in the second half (...) of the eighteenth century - occur in states of 'technological exception'. In them, values are suspended and rules, limits and security norms are absent; and, in the face of risks, losses and harm to health and environment that are occasioned by technological applications introduced in the name of economical progress , normal social inhibitions become suspended in the name of furthering the values of capital and market. In addition, I show that maintaining technological exception has favored, on the one hand, the development by large corporations of antiscientific practices that threaten the moral integrity of science by impeding the proper use of the scientific method for evaluating the consequences of using technologies that are protected by patents; and, on the other hand, under the cover of ignorance, continued deterioration of the environment that threatens the very survival of the human species.

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. I conclude by pointing out some consequences of the previous discussion for the future of Critical Theory. (shrink)

A group of philosophers suggests that a sense of mineness intrinsically contained in the phenomenal structure of all conscious experiences is a necessary condition for a subject to become aware of himself as the subject of his experiences i.e. self-awareness. On this view, consciousness necessarily entails phenomenal self-awareness. This paper argues that cases of delusions of thought insertion undermine this claim and that such a phenomenal feature plays little role in accounting for the most minimal type of self-awareness entailed by (...) phenomenal consciousness. First, I clarify the main view endorsing this claim i.e. the Self-Presentational View of Consciousness and formulate the challenge from thought insertion. After, I offer a systematic evaluation of all the strategies used by the advocates of this view to deal with this challenge. Finally, I conclude that most of these strategies are unsatisfactory for they rest in unwarranted premises, imprecisions about the agentive nature of cognitive experiences, and especially, lack of distinction between the different ways in which subjects can become aware of their own thoughts.

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. -/- .

Behavior analysis emphasizes the study of overt animal (human and nonhuman) behavior as a subject matter in its own right. This paper provides a metaphysical foundation for such an emphasis via an elucidation of a thesis that I generically call "realism about behavior," where by "realism" I mean an assertion of mind-independent existence. The elucidation takes the form of a conceptual framework that combines a property-exemplification account of events with modal realism in the context of three opposing philosophies of mind: (...) property dualism, reductive physicalism, and type behaviorism. Each philosophy leads to the thesis that at least one possible world exists in which counterparts of all actual behavioral events occur and no counterpart of any actual "mental" (either nonphysical, neuro-mental, or behavioro-mental) event occurs. The third thesis is false because it violates the assumption that nothing can exist independently of itself, which leads to a rejection of type behaviorism. The other two theses provide the sought-after foundation through a counterfactual characterization of behavior qua behavior as a scientific subject matter. Its study thus becomes the study of behavior as if the nonphysical and the neural did not exist, even if they may factually exist and play a causal role in behavior. Some implications are discussed.

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).

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)

In the following essay I present a narrative of the development of astronomical models from Eudoxus to Kepler, as a case-study that vindicates an insightful and influential recent account of the concept of scientific understanding.

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).

Whenever a fact P grounds another fact Q, one may ask why that is so. Karen Bennett and Louis deRosset independently argue that grounding facts—such as the fact that P grounds Q—are always grounded in their grounds-part. Bennett calls this the view that grounding is superinternal. My aim in this paper is to argue that grounding is not superinternal. I will do so by showing that superinternality, together with some widely accepted formal features of grounding—namely, transitivity and necessitation—yield implausible claims (...) about how necessities are explained. Then, I will discuss how my argument compares with Dasgupta's argument against superinternality. (shrink)

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.

Against the charge that Kant's doctrine of radical evil is inconsistent and alien to his practical philosophy, my aim is to show its necessity within the critical system. First, I undermine the alleged vacuity of Kant's notion of evil by showing that, already in the Groundwork, an evil will is the necessary conceptual correlate of a good will. "Good" and "evil" characterize the agent's form of willing and represent the source of value of right and wrong actions. Then, I show (...) how the doctrine of radical evil derives from Kant's notion of evil. That evil lies at the level of an individual Gesinnung is the result of Kant's radicalizing the use of transcendental freedom. That there is a propensity to evil in the whole species is the result of Kant's naturalizing the principles of his moral psychology. Although Kant is not clear about this distinction, the consistency of his doctrine depends on indicating that an "evil Gesinnung" and the "propensity to evil" are not equivalent concepts. Rather, they refer to different units of moral analysis, the individual and the whole species, and represent a failure to comply with different types of moral obligation: the duty to realize the good and the duty to realize the highest good. The correlation between units of moral analysis and types of obligation explains the isomorphism that Kant detects between them, as well as their logical independence, without which the individual's choice of Gesinnung would be analytically contained in the species' choice of moral nature . Finally, to account for the problem of moral self-constitution I argue for the necessity of assuming a transcendental volitional structure, the unity of acknowledgement or "I will". At the different levels of analysis, this structure organizes the will's manifold intentions according to unifying principles that allow it to recognize them as its own. Although Kant does not mention it, the "I will" is a necessary assumption to account for the continuity of choice and for its possible imputation to an agent. (shrink)

In this dissertation, I argue that we should reframe the presentation and defense of the program of discourse ethics and deliberative democracy (DEP) in such a way that we make clear its connection to the substantive moral ideas of solidarity, equality and freedom. This program basically says that we should, when we can, determine the validity of the norms regulating our social life through practices of public deliberation. If we want to understand why engaging in public deliberation makes moral sense, (...) or is obligatory, we need to make explicit the connection between the formal procedures of deliberation and our most basic substantive moral ideas of freedom, equality and solidarity. In order to unpack this claim, I construct what I call an expressive-elaboration model of the relation between substance and procedure in public deliberation. According to this model, we should see the two dimensions as working in tandem, in such a way that deliberative procedures are understood as the medium of expression and elaboration of our basic substantive ideas of solidarity, equality and freedom. The three ideas are expressed in the fact and form of deliberation, and elaborated in their changing and specific interpretations as topics and consequences of deliberative practices. To develop this model, I start with a consideration of certain insights of Kant's moral theory, and proceed to bridge the gap between Habermas's more formalistic and Rawls's more substantive neo-Kantian accounts of practical reason. The result is a straightforwardly substantive articulation and defense of the dialogic procedures of DEP based on the recognition of the fact of widespread moral disagreement and a fundamental project of justice demanding that we deal with that condition of disagreement by constructing social arrangements in which we include each other, solidaristically, as free and equal members. This morally substantive defense of DEP referring to the fact of widespread moral disagreement and the fundamental project of justice is different from, and more compelling than, other common, formalistic and prudential defenses of DEP.

This paper offers an exploration of the socialist principle “From each according to their abilities, to each according to their needs.” The Abilities/Needs Principle is arguably the ethical heart of socialism but, surprisingly, has received almost no attention by political philosophers. I propose an interpretation of the principle and argue that it involves appealing ideas of solidarity, fair reciprocity, recognition of individual differences, and meaningful work. The paper proceeds as follows. First, I analyze Marx’s formulation of the Abilities/Needs Principle. Second, (...) I identify the principle’s initial plausibility, but show that it faces serious problems that cannot be addressed without developing a fresh interpretation of it. Third, I provide an interpretation of the principle that highlights demands concerning opportunities for self-realization in work, positive duties of solidarity, sensitivity to individual differences, and mechanisms of fair reciprocity. Fourth, I discuss a possible institutional implementation of the Abilities/Needs Principle. Finally, I identify some normative puzzles about the transition from capitalism to socialism, and suggest how the Abilities/Needs Principle might gain motivational traction by mobilizing the powerful idea of human dignity.

In a recent article, Fabrice Correia explores the project of reducing the notion of grounding to that of essence. He then goes on to provide several candidate definitions and test each of them against a number of objections. His final take on the situation is, roughly, that two of the definitions can handle all of the considered objections. The aim of this paper is to re-evaluate Correia's conclusions in the light of two sources of insights: Firstly, I will argue that (...) one of the objections treated by Correia has been somewhat underestimated, and that it still constitutes a threat against definitions of grounding in terms of essence. Secondly, there are at least two further objections that should be considered by the advocate of such definitions. As I will show, one of them can be neutralized; but the other one is more serious and suggests a clear dialectical edge to an operationalist definition. (shrink)

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)

If God knew I were going to write this paper, was I able to refrain from writing it this morning? One possible response to this question is that God's knowledge does not take place in time and therefore He does not properly fore-know. According to this response, God knows absolutely everything, it's just that He knows everything outside of time. The so-called timeless solution was one of the influential responses to the foreknowledge problem in classical Christian Theology. This solution, however, (...) seemed to lose support in the recent debate. For example, Pike claims that "the doctrine of God's timelessness entered Christian Theology because Platonic thought was stylish at the time" and Hasker catalogues this as one of the minor solutions to the problem. One possible source for this general attitude towards timelessness is the thought that the very idea of timelessness is incoherent. In this paper I argue that that the timeless solution to the foreknowledge problem is congenial with the supervaluationist theory of branching time and that this formal framework provides, in fact, a precise characterization of the timeless solution to the foreknowledge problem. The views presented in this paper are in line with those of Kretzmann and Stump, Leftow and De Florio and Frigerio. (shrink)
