We study active set methods for optimization problems in Block Angular Form (BAF). We begin by reviewing some standard basis factorizations, including Saunders' orthogonal factorization and updates for the simplex method that do not impose any restriction on the pivot sequence and maintain the basis factorization structured in BAF throughout the algorithm. We then suggest orthogonal factorization and updating procedures that allow coarse grain parallelization, pivot updates local to the affected blocks, and independent block reinversion. A simple parallel environment appropriate (...) to the description and complexity analysis of test procedures is defined in Section 5. The factorization and updating procedures are presented in Sections 6 and 7. Our update procedure outperforms conventional Updating procedures even in a purely sequential environment. (shrink)

Two major clarifications have greatly abetted the understanding and fruitful expansion of the theory of natural selection in recent years: the acknowledgment that interactors, not replicators, constitute the causal unit of selection; and the recognition that interactors are Darwinian individuals, and that such individuals exist with potency at several levels of organization (genes, organisms, demes, and species in particular), thus engendering a rich hierarchical theory of selection in contrast with Darwin’s own emphasis on the organismic level. But a piece of (...) the argument has been missing, and individuals at levels distinct from organisms have been denied potency (although granted existence within the undeniable logic of the theory), because they do not achieve individuality with the same devices used by organisms and therefore seem weak by comparison. We show here that different features define Darwinian individuality across scales of size and time. In particular, species-individuals may develop few emergent features as direct adaptations. The interactor approach works with emergent fitnesses, not with emergent features; and species, as a consequence of their different mechanism for achieving individuality (reproductive exclusivity among subparts, that is, among organisms), express many effects from other levels. Organisms, by contrast, suppress upwardly cascading effects, because the organismic style of individuality (by functional integration of subparts) does not permit much competition or differential reproduction of parts from within. Species do not suppress the operation of lower levels; such effects therefore become available as exaptations conferring emergent fitness—a primary source of the different strength that species achieve as effective Darwinian individuals in evolution.

This study investigated the effect of urbanization pull indices on the viability of small businesses in the Calabar Metropolis. The investigation was guided by two objectives, two research questions, and two null hypotheses. The study covered 3001 small scale business operators, comprising 2,800 Operators of Manufacturing Industry (OMIs) and 201 Operators of Service Industry (OSIs). A total of 352 participants was the sample of the study. The Taro Yamane formula was used to generate the sample. The Urbanization Pull Indices and (...) the Small-Scale Business (SSB) Sustainability Questionnaire was used to collect data. This instrument was trial-tested on 30 respondents from within and outside the study area. Cronbach Alpha statistics were used to determine internal consistency, yielding reliability coefficients of 0.83 and 0.79 for the instrument. Mean statistics were used to answer the research questions, while independent t-test was used to test the null hypotheses at .05 level of significance. The findings indicate that the mean ratings for the effect of infrastructure and government policies on SSB sustainability in the Calabar metropolitan area did not differ significantly across OMIs and OSIs. Based on these findings, the study recommends that the state government make it easier for small businesses to run sustainably. (shrink)

Higher-Order Thought (HOT) theories of consciousness maintain that the kind of awareness necessary for phenomenal consciousness depends on the cognitive accessibility that underlies reporting. -/- There is empirical evidence strongly suggesting that the cognitive accessibility that underlies the ability to report visual experiences depends on the activity of the dorsolateral prefrontal cortex (dlPFC). This area, however, is highly deactivated during the conscious experiences we have during sleep: dreams. HOT theories are jeopardized, as I will argue. I will briefly present HOT (...) theories in the first section. Section 2 offers empirical evidence to the effect that the cognitive accessibility that underlies the ability to report depends on the dorsolateral prefrontal cortex: dlPFC is the neural correlate of HOTs. Section 3 shows the evidence we have of the deactivation of this brain area during dreams and, in section 4, I present my argument. Finally, I consider and rejoin two possible replies that my opponent can offer: the possibility of an alternative neural correlate of HOTs during dreams and the denial that we have phenomenally conscious experiences during sleep.

In this essay we will consider another basic topic: the problem of the nature of the distinctions between Sitte, Brauch, Wert, Mode, and Recht, on which Weber's discussion relies. These discussions typically involved the untranslatable concept of Sitte, which marks a contrast between practices or customs with normative force and “mere practice.” There is a close parallel to this distinction in American social thought in W. G. Sumner's latinate distinction between the mores and folkways of a society. In what follows (...) we shall simply use the German term as a reminder of its long history in German philosophy. Weber was obviously aware of this history, as was Jhering. Our aim will be to examine Weber's modifications of the received version of these distinctions and to consider the Implications of these modifications. As we shall see, what Weber represents as an innocuous classificatory problem contains a much more significant conceptual transformation, which bears on the general image of modernity as rationalization constructed by Weber.

What is the primary function of consciousness in the nervous system? The answer to this question remains enigmatic, not so much because of a lack of relevant data, but because of the lack of a conceptual framework with which to interpret the data. To this end, we have developed Passive Frame Theory, an internally coherent framework that, from an action-based perspective, synthesizes empirically supported hypotheses from diverse fields of investigation. The theory proposes that the primary function of consciousness is well-circumscribed, (...) serving the 'somatic nervous system[. For this system, consciousness serves as a frame that constrains and directs skeletal muscle output, thereby yielding adaptive behavior. The mechanism by which consciousness achieves this is more counterintuitive, passive, and “low level” than the kinds of functions that theorists have previously attributed to consciousness. Passive frame theory begins to illuminate (a) what consciousness contributes to nervous function, (b) how consciousness achieves this function, and (c) the neuroanatomical substrates of conscious processes. Our untraditional, action-based perspective focuses on olfaction instead of on vision and is 'descriptive' (describing the products of nature as they evolved to be) rather than 'normative' (construing processes in terms of how they should function). Passive frame theory begins to isolate the neuroanatomical, cognitive-mechanistic, and representational (e.g., conscious contents) processes associated with consciousness. (shrink)

After a long hiatus, psychology and philosophy are returning to formal study of imagination. While excellent work is being done in the current environment, this article argues for a stronger thesis than usually adopted. Imagination is not just a peripheral feature of cognition or a domain for aesthetic research. It is instead the core operating system or cognitive capacity for humans and has epistemic and therapeutic functions that ground all our sense-making activities. A sketch of imagination as embodied cognition is (...) offered, followed by suggestions of how to organize imagination studies into a more rigorous science–humanities research area. (shrink)

A mythopoetic paradigm or perspective sees the world primarily as a dramatic story of competing personal intentions, rather than a system of objective impersonal laws. Asma argued that our contemporary imaginative cognition is evolutionarily conserved-it has structural and functional similarities to premodern Homo sapiens’s cognition. This article will outline the essential features of mythopoetic cognition or adaptive imagination, delineate the adaptive sociocultural advantages of mythopoetic cognition, explain the phylogenetic and ontogenetic mechanisms that give rise to human mythopoetic mind, show how (...) mythopoetic cognition challeng­es contemporary trends in cognitive science and philosophy, and recognize and outline empirical approaches for a new cognitive science of the imagination.

[Stephen Yablo] The usual charge against Carnap's internal/external distinction is one of 'guilt by association with analytic/synthetic'. But it can be freed of this association, to become the distinction between statements made within make-believe games and those made outside them-or, rather, a special case of it with some claim to be called the metaphorical/literal distinction. Not even Quine considers figurative speech committal, so this turns the tables somewhat. To determine our ontological commitments, we have to ferret out all traces (...) of nonliterality in our assertions; if there is no sensible project of doing that, there is no sensible project of Quinean ontology. /// [Andre Gallois] I discuss Steve Yablo's defence of Carnap's distinction between internal and external questions. In the first section I set out what I take that distinction, as Carnap draws it, to be, and spell out a central motivation Carnap has for invoking it. In the second section I endorse, and augment, Yablo's response to Quine's arguments against Carnap. In the third section I say why Carnap's application of the distinction between internal and external questions runs into trouble. In the fourth section I spell out what I take to be Yablo's version of Carnap. In the last I say why that version is especially vulnerable to the objection raised in the second. (shrink)

Over the last fifteen years, an ambitious explanatory framework has been proposed to unify explanations across biology and cognitive science. Active inference, whose most famous tenet is the free energy principle, has inspired excitement and confusion in equal measure. Here, we lay the ground for proper critical analysis of active inference, in three ways. First, we give simplified versions of its core mathematical models. Second, we outline the historical development of active inference and its relationship to other theoretical approaches. Third, (...) we describe three different kinds of claim -- labelled mathematical, empirical and general -- routinely made by proponents of the framework, and suggest dialectical links between them. Overall, we aim to increase philosophical understanding of active inference so that it may be more readily evaluated. -/- This the final submitted version of the Introduction to the Topical Collection "The Free Energy Principle: From Biology to Cognition", forthcoming in Biology & Philosophy.

This paper aims to establish several interconnected points. First, a particular interpretation of the mathematical definition of information, known as the causal interpretation, is supported largely by misunderstandings of the engineering context from which it was taken. A better interpretation, which makes the definition and quantification of information relative to the function of its user, is outlined. The first half of the paper is given over to introducing communication theory and its competing interpretations. The second half explores three consequences of (...) the main thesis. First, a popular claim that the quantification of information in a signal is irrelevant for the meaning of that signal is exposed as fallacious. Second, a popular distinction between causal and semantic information is shown to be misleading, and I argue it should be replaced with a related distinction between natural and intentional signs. Finally, I argue that recent empirical work from microbiology and cognitive science drawing on resources of mathematical communication theory is best interpreted by the functional account. Overall, a functional approach is shown to be both theoretically and empirically well-supported. (shrink)

Higher-order thought theories of consciousness attempt to explain what it takes for a mental state to be conscious, rather than unconscious, by means of a HOT that represents oneself as being in the state in question. Rosenthal Consciousness and the self: new essays, Cambridge University Press, Cambridge, 2011) stresses that the way we are aware of our own conscious states requires essentially indexical self-reference. The challenge for defenders of HOT theories is to show that there is a way to explain (...) the required reference-fixing mechanisms that is compatible with the theory. According to Rosenthal, the reference to oneself as such is grounded in the disposition to identify the individual the HOT refers to as the individual who has that HOT. I argue that this leads to a vicious infinite regress on the more than plausible assumption that our cognitive capacities are limited. This leaves such theories without a foundation, since self-reference is thought essential to consciousness. (shrink)

Public health care interventions—regarding vaccination, obesity, and HIV, for example—standardly take the form of information dissemination across a community. But information networks can vary importantly between different ethnic communities, as can levels of trust in information from different sources. We use data from the Greater Pittsburgh Random Household Health Survey to construct models of information networks for White and Black communities--models which reflect the degree of information contact between individuals, with degrees of trust in information from various sources correlated with (...) positions in that social network. With simple assumptions regarding belief change and social reinforcement, we use those modeled networks to build dynamic agent-based models of how information can be expected to flow and how beliefs can be expected to change across each community. With contrasting information from governmental and religious sources, the results show importantly different dynamic patterns of belief polarization within the two communities. (shrink)

The flight to reference is a widely-used strategy for resolving philosophical issues. The three steps in a flight to reference argument are: (1) offer a substantive account of the reference relation, (2) argue that a particular expression refers (or does not refer), and (3) draw a philosophical conclusion about something other than reference, like truth or ontology. It is our contention that whenever the flight to reference strategy is invoked, there is a crucial step that is left undefended, and that (...) without a defense of this step, the flight to reference is a fatally flawed strategy; it cannot succeed in resolving philosophical issues. In this paper we begin by setting out the flight to reference strategy and explaining what is wrong with arguments that invoke the strategy. We then illustrate the problem by considering arguments for and against eliminative materialism. In the final section we argue that much the same problem undermines Philip Kitcher's attempt to defend scientific realism. (shrink)

The notion of the human embryo is not immutable. Various scientific and technological breakthroughs in reproductive biology have compelled us to revisit the definition of the human embryo during the past 2 decades. Somatic cell nuclear transfer, oocyte haploidisation and, more recently, human stem cell-derived embryo models have challenged this scientific term, which has both ethical and legal repercussions. Here, we offer a legal perspective to identify a universally accepted definition of ‘embryo’ which could help to ease and unify the (...) regulation of such entities in different countries. (shrink)

This paper champions the view (REG) that the concept of a normative reason for an agent S to perform an action A is that of an explanation why it would be good (in some way, to some degree) for S to do A. REG has numerous virtues, but faces some significant challenges which prompt many philosophers to be skeptical that it can correctly account for all our reasons. I demonstrate how five different puzzles about normative reasons can be solved by (...) attention to the concept of goodness, and in particular observing the ways in which it—and consequently, talk about reasons—is sensitive to context (ends and information). Rather than asking simply whether or not certain facts are reasons for S to do A, we need to explore the contexts in which it is and is not correct to describe a certain fact as “a reason” for S to do A. These five puzzles concern: (1) reasons for attitudes of the “right kind”, (2) evidence as reasons, (3) normative facts as reasons, (4) subjective reasons, and (5) attitudes as reasons. (shrink)

Despite a recent surge of interest in philosophy as a way of life, it is not clear what it might mean for philosophy to guide one's life, or how a “philosophical” way of life might differ from a life guided by religion, tradition, or some other source. We argue against John Cooper that spiritual exercises figure crucially in the idea of philosophy as a way of life—not just in the ancient world but also today, at least if the idea is (...) to be viable. In order to make the case we attempt to clarify the nature of spiritual exercises, and to explore a number of fundamental questions, such as “What role does reason have in helping us to live well?” Here we distinguish between the discerning and motivational powers of reason, and argue that both elements have limitations as guides to living well.

Alleged self-evidence aside, conceivability arguments are one of the main reasons in favor of the claim that there is a Hard Problem. These arguments depend on the appealing Kripkean intuition that there is no difference between appearances and reality in the case of consciousness. I will argue that this intuition rests on overlooking a distinction between cognitive access and consciousness, which has received recently important empirical support. I will show that there are good reasons to believe that the intuition is (...) misguided—at least on the reading that the conceivability arguments require—and hence that the arguments are unsupported. This, in turn, alleviates the Hard Problem but leaves us with what I think is a not easy problem. (shrink)

The well-known distinction between access consciousness and phenomenal consciousness has moved away from the conceptual domain into the empirical one, and the debate now is focused on whether the neural mechanisms of cognitive access are constitutive of the neural correlate of phenomenal consciousness. In this paper, I want to analyze the consequences that a negative reply to this question has for the cognitive phenomenology thesis – roughly the claim that there is a “proprietary” phenomenology of thoughts. If the mechanisms responsible (...) for cognitive access can be disentangled from the mechanisms that give rise to phenomenology in the case of perception and emotion, then the same disentanglement is to be expected in the case of thoughts. This, in turn, presents, as I argue, a challenge to the cognitive phenomenology thesis: either there are thoughts with cognitive phenomenology we lack cognitive access to or there are good reasons to doubt that there is such a thing as cognitive phenomenology. I discuss a... (shrink)

Analytic semantics got its start when Frege pointed out differences in cognitive content between sentences that in some good sense “say the same.” Frege put cognitive content (in the form of sense) at the heart of semantic content. Most prefer nowadays to see cognitive contents as generated by semantic contents in context; a sentence's cognitive significance is an aspect rather of the information imparted by its use. I argue for a particular version of this idea. Semantic contents generate cognitive contents (...) by operating levers in a larger piece of machinery, involving also the presupposition P one is leaning on and the subject matter M under discussion. A sentence's cognitive content is what its literal-content-restricted-to-P-worlds says about M. It's by triggering different presuppositions and/or different subject matters that coreferential names make their distinctive mark on a sentence's felt information value. (shrink)

Explaining agency is a significant challenge for those who are interested in the sciences of the mind, and non-representationalists are no exception to this. Even though both ecological psychologists and enactivists agree that agency is to be explained by focusing on the relation between the organism and the environment, they have approached it by focusing on different aspects of the organism-environment relation. In this paper, I offer a suggestion for a radical embodied account of agency that combines ecological psychology with (...) recent trends in enactive cognitive science. According to this proposal, while enactivism focuses primarily on describing how our acquired sensorimotor schemes and habits mutually equilibrate, affecting our tendency to act upon some affordances instead of others, ecological psychology focuses on studying how perceptual information contributes to the actualization of the sensorimotor schemes and habits without mediating representations, inferences, and computations. The paper concludes by briefly exploring how this ecological-enactive theory of agency can account for how socio-cultural norms shape human agency. (shrink)

For anyone approaching the Encheiridion of Epictetus for the first time, this book provides a comprehensive guide to understanding a complex philosophical text. Including a full translation and clear explanatory commentaries, Epictetus's 'Encheiridion' introduces readers to a hugely influential work of Stoic philosophy. Scott Aikin and William O. Stephens unravel the core themes of Stoic ethics found within this ancient handbook. Focusing on the core themes of self-control, seeing things as they are, living according to nature, owning one's roles and (...) fulfilling the responsibilities that those roles entail, the authors elucidate the extremely challenging ideas in Epictetus's brisk chapters. Divided into five distinct parts, this book provides readers with: -/- - A new translation of the Encheiridion by William O. Stephens. - A new introduction to ancient Stoicism, its system of concepts, and the ancient figures who shaped it. - A fresh treatment of the notorious and counter-intuitive 'Stoic paradoxes'. - An accessible overview of the origin and historical context of the Encheiridion. - Detailed commentaries on each chapter of the Encheiridion that clarify its recurring themes and highlight their interconnections. - Careful attention to the presentation of the arguments embedded in Epictetus's aphoristic style. - A thoughtful discussion of serious criticisms of Epictetus's Stoicism and replies to these objections. -/- Written with clarity and authority, Epictetus's 'Encheiridion' provides a foundation from which readers can understand this important text and engage with the fundamental questions of Stoic philosophy and ethics. This guide will aid teachers of Epictetus, students encountering Stoicism for the first time, and readers seeking a greater understanding of Stoic ethics. (shrink)

Recent experimental studies indicate that epistemically irrelevant factors can skew our intuitions, and that some degree of scepticism about appealing to intuition in philosophy is warranted. In response, some have claimed that philosophers are experts in such a way as to vindicate their reliance on intuitions—this has become known as the ‘expertise defence’. This paper explores the viability of the expertise defence, and suggests that it can be partially vindicated. Arguing that extant discussion is problematically imprecise, we will finesse the (...) notion of ‘philosophical expertise’ in order to better reflect the complex reality of the different practices involved in philosophical inquiry. On this basis, we offer a new version of the expertise defence that allows for distinct types of philosophical expertise. The upshot of our approach is that wholesale vindications or rejections of the expertise defence are shown to be unwarranted; we must instead turn to local, piecemeal investigations of philosophical expertise. Lastly, in the spirit of taking our own advice, we exemplify how recent developments from experimental philosophy lend themselves to this approach, and can empirically support one instance of a successful expertise defence.

Este artigo consiste em abordagem de cunho introdutório sobre a crítica à metafísica. Destacam-se elementos isolados do conteúdo de crítica à metafísica na modernidade e que tende a vir a ser desenvolvido na contemporaneidade. Com isso quer-se dizer que na passagem da modernidade para a contemporaneidade a filosofia acaba por incorporar o conteúdo de crítica à metafísica e evolui na direção de vir a reconhecer sua condição de ser metafísica e de empreender crítica a essa condição. Para estabelecer a abordagem (...) do assunto procura-se aqui manter subjacente a ideia de crítica à metafísica no contexto da história da filosofia; mas é priorizado nisso o aspecto temático em vez de seu aspecto histórico. Busca-se mostrar que no processo de compreender a crítica à metafísica tem ocorrido de se tentar apartar do caráter de metafísico o caráter de teórico da ciência. Requer então indagar se é possível estabelecer marco de separação entre uma coisa e a outra. Em vez de separação opta-se aqui por investir no conhecimento da identidade da própria metafísica como saber filosófico; busca-se esclarecer que a pergunta pelo que é filosofia e a dificuldade de compreender o seu conteúdo é o que traz à tona a crítica à metafísica e a torna necessária, mas como modo de se compreender melhor o que é filosofia.

According to F. Adams [this journal, vol. 68, 2018] cognition cannot be realized in plants or bacteria. In his view, plants and bacteria respond to the here-and-now in a hardwired, inflexible manner, and are therefore incapable of cognitive activity. This article takes issue with the pursuit of plant cognition from the perspective of an empirically informed philosophy of plant neurobiology. As we argue, empirical evidence shows, contra Adams, that plant behavior is in many ways analogous to animal behavior. This renders (...) plants suitable to be described as cognitive agents in a non-metaphorical way. Sections two to four review the arguments offered by Adams in light of scientific evidence on plant adaptive behavior, decision-making, anticipation, as well as learning and memory. Section five introduces the ‘phyto-nervous’ system of plants. To conclude, section six resituates the quest for plant cognition into a broader approach in cognitive science, as represented by enactive and ecological schools of thought. Overall, we aim to motivate the idea that plants may be considered genuine cognitive agents. Our hope is to help propel public awareness and discussion of plant intelligence once appropriately stripped of anthropocentric preconceptions of the sort that Adams' position appears to exemplify.

Alison Gopnik and Andrew Meltzoff have argued for a view they call the ‘theory theory’: theory change in science and children are similar. While their version of the theory theory has been criticized for depending on a number of disputed claims, we argue that there is a fundamental problem which is much more basic: the theory theory is multiply ambiguous. We show that it might be claiming that a similarity holds between theory change in children and (i) individual scientists, (ii) (...) a rational reconstruction of a Superscientist, or (iii) the scientific community. We argue that (i) is false, (ii) is non-empirical (which is problematic since the theory theory is supposed to be a bold empirical hypothesis), and (iii) is either false or doesn’t make enough sense to have a truth-value. We conclude that the theory theory is an interesting failure. Its failure points the way to a full, empirical picture of scientific development, one that marries a concern with the social dynamics of science to a psychological theory of scientific cognition.

La Neuroteología surge como una nueva forma de explicar las relaciones entre el ser humano y Dios, las religiones y la espiritualidad en general a partir de la neurología (estudio del sistema nervioso, especialmente del encéfalo).

En este trabajo deseo exponer de qué manera algunas formas de Neuroteología manifiestan un rasgo sintomático de la cultura actual donde la ciencia actúa como un saber omnímodo que aspira explicar (...) todos los aspectos de la realidad pasando por alto sus propios límites metodológicos. Algunos investigadores transgreden los principios del método científico-experimental para extrapolarlos a cuestiones filosóficas y teológicas.

Actually, some researchers transgress the principles of the scientific-experimental method and extrapolate to philosophical and theological issues. In this way, they overlap the epistemological limits of the different kinds of knowledge to become one only. Thus, science carries out, to say the least, a naturalist reductionism. (shrink)

ABSTRACT This article offers the first step in an ongoing project of revisiting the foundations of latinidad and lo latinoamericano by focusing on the exclusions enacted by the history of these concepts and the cultural and political identity that comes with them. In conversation with Susana Nuccetelli and Omar Rivera, the author focuses on two emblematic authors in the history of Latin American philosophy (Simón Bolívar and José de Vasconcelos) that are usually read as offering a novel, liberatory conception of (...) the Latin American reality/identity, categorically different from European and Anglo-American conceptions. This common reading of some of the foundational texts on Latin American identity, however, conceals not only the active, textual removal of Blackness in the construction of this identity, but also the literal subtraction of Black bodies, lives, and histories from the Latin American nations and communities. Both of these elements are an explicit part of the philosophical programs of Bolívar and Vasconcelos. The article shows how the thought and political practice of these two authors, celebrated in different ways as foundational of what we understand as Latin America today, exemplify the exclusionary historical demarcation of latinidad.

This article is a rebuttal to Robert G. Cavin and Carlos A.

As such, they argue that William Lane Craig’s resurrection hypothesis is not only incompatible with the notion of Jesus physically appearing to the (...) disciples, but the resurrection hypothesis is significantly limited in both its explanatory scope and explanatory power. This article seeks to demonstrate why their use of the Standard Model does not logically entail a rejection of the physical resurrection of Jesus when considering the scope and limitations of science itself.

Ecological psychology is one of the most influential theories of perception in the embodied, anti-representational, and situated cognitive sciences. However, radical enactivists claim that Gibsonians tend to describe ecological information and its ‘pick up’ in ways that make ecological psychology close to representational theories of perception and cognition. Motivated by worries about the tenability of classical views of informational content and its processing, these authors claim that ecological psychology needs to be “RECtified” so as to explicitly resist representational readings. In (...) this paper, we argue against this call for RECtification. To do so, we offer a detailed analysis of the notion of perceptual information and other related notions such as specificity and meaning, as they are presented in the specialized ecological literature. We defend that these notions, if properly understood, remain free of any representational commitment. Ecological psychology, we conclude, does not need to be RECtified. (shrink)

Spatially situated opinions that can be held with different degrees of conviction lead to spatiotemporal patterns such as clustering (homophily), polarization, and deadlock. Our goal is to understand how sensitive these patterns are to changes in the local nature of interactions. We introduce two different mixing mechanisms, spatial relocation and nonlocal interaction (“telephoning”), to an earlier fully spatial model (no mixing). Interestingly, the mechanisms that create deadlock in the fully spatial model have the opposite effect when there is a sufficient (...) amount of mixing. With telephoning, not only is polarization and deadlock broken up, but consensus is hastened. The effects of mixing by relocation are even more pronounced. Further insight into these dynamics is obtained for selected parameter regimes via comparison to the mean-field differential equations. (shrink)

Considering the war context and the emergence of the avant-garde in the early twentieth century, I base on this work the reasons why the presence of the concept of nivola, attributed by Miguel de Unamuno to refer to the literary technique used in his novel Mist (1914), provokes a possible confrontation between universes composed of elements of reality and the virtual. In that sense, it will be appropriate to explain the procedure that originates that collision of established plans. For this, (...) I will resort to literary categories that support the theories of fiction, according to the perception of Thomas Pavel and Marie-Laure Ryan. (shrink)

In having an experience one is aware of having it. Having an experience requires some form of access to one's own state, which distinguishes phenomenally conscious mental states from other kinds of mental states. Until very recently, Higher-Order (HO) theories were the only game in town aiming at offering a full-fledged account of this form of awareness within the analytical tradition. Independently of any objections that HO theories face, First/Same-Order (F/SO) theorists need to offer an account of such access to (...) become a plausible alternative. My aim in this paper is twofold. In the first place, I wish to widen the logical space of the discussion among theories of consciousness by offering a distinction, orthogonal to that between F/SO and HO theories, between what I will call 'Self-Involving' (SI) and 'Mental-State-Involving' (MSI) theories and argue in favor of the former one. In the second place, I will present the basics of a characterization of such a Self-Involving theory in Same-Order terms. (shrink)

Para ello, (...) recurriré a categorías literarias que sustentan las teorías de la ficción, según la percepción de Thomas Pavel y Marie-Laure Ryan. (shrink)

Hume thought that if you believed in powers, you believed in necessary connections in nature. He was then able to argue that there were none such because anything could follow anything else. But Hume wrong-footed his opponents. A power does not necessitate its manifestations: rather, it disposes towards them in a way that is less than necessary but more than purely contingent. -/- In this paper a dispositional theory of causation is offered. Causes dispose towards their effects and often produce (...) them. But a set of causes, even though they may succeed in producing an effect, cannot necessitate it since the effect could have been counteracted by some additional power. This would require a separation of our concepts of causal production and causal necessitation. The most conspicuous cases of causation are those where powers accumulate and pass a requisite threshold for an effect to occur. -/- We develop a model for representing powers as constituent vectors within an n-dimensional quality space, where composition of causes appears as vector addition. Even our resultant vector, however, has to be understood as having dispositional force only. This model throws new light on causal modality and cases of prevention, causation by absence and probabilistic causation. (shrink)

Many Christian thinkers have embraced the notion “art for art’s sake.” Chesterton did not. To the contrary, he saw such an idea as deeply problematic for a Christian aesthetic. In the following article, I will explore some philosophical aspects of the “art for art’s sake” movement and then explain why Chesterton parted company with it.

The different “postmodern” philosophies that arose from the 1970s to the 1990s have often been considered as a kind of irrationalist-skeptical-relativist “ideology” or assorted amalgam, which in our time would dangerously take over the philosophical academy and western cultures, with grave risk for universalist or simply rationalist projects. Nevertheless, as the title of this article shows, a closer examination of some trends of postmodern thought would be able to perceive that they not only are uncomfortable with the label “relativist,” “irrationalist” (...) or “skeptical,” but also that they offer substantial arguments against, for example, the main theses of relativism. Naturally, none of these trends has any qualms about abominating universalism as well (the presumed mortal enemy of the relativists). Thus the most sensible conclusion would be that what really seems erroneous to authors such as those we shall approach here is the presumed dilemma (presented as inevitable) between relativism and universalism (it is curious that, at least as far as faith in the existence of such a dichotomy is concerned, these presumed irreconcilable enemies, which both the relativists and the universalists believe themselves to be, are plainly in agreement). Only if they subscribe to such a rejection of this dilemma could it be explained that important thinkers of the heterogeneous postmodern group (such as those whom I propose to have a dialogue with in this article) have scorned, on the one hand, any and all universal project of rationality, but have also strongly disallowed relativist proposals (just as, naturally, they have likewise taken advantage of the issue to deny their presumed adherence to relativism as such). This idea, however, has not been understood by a large part of the scholars involved today in epistemology and practical philosophy (the two philosophical specialties in which one most frequently faces the question of relativism). To approach this understanding, therefore, perhaps it would not be amiss to review the different arguments that some postmodern thinkers use against relativism. Specifically, we shall tale a look at the reasoning in this sense that has come from Gianni Vattimo (1936), Paul K. Feyerabend (1924-1994), and Richard Rorty (1931). All of them have too often had to suffer from the suspicion of being considered as relativists. To absolve philosophers such as these from such an accusation seems to be a sine qua non condition for understanding their true position towards the universalism versus relativism dilemma. (shrink)

The traditional view according to which we adults tacitly consent to a state’s lawful actions just by living within its borders—the residence theory—is now widely rejected by political philosophers. According to the critics, this theory fails because consent must be (i) intentional, (ii) informed, and (iii) voluntary, whereas one’s continued residence within a state is typically none of these things. Few people intend to remain within the state in which they find themselves, and few realize that by remaining they are (...) consenting to the state’s lawful actions. In addition, the various obstacles standing in the way of us leaving the state render our remaining involuntary. Thus, the critics conclude, few if any people can be considered to have consented through their residence. I argue that these objections fail and that the residence theory remains a viable option, at least for those who are not committed incompatibilists. (shrink)

Los sótanos del universo plantea la necesidad de cambiar la epistemología del conocimiento apodíctico científico-filosófico basado en la certidumbre por la “epistemología del riesgo”. Asimismo, sugiere un mayor acercamiento entre ciencia y filosofía para superar la actual confusión y estancamiento que afectan a estos saberes. Este artículo analiza ambos temas. -/- Los Sótanos del Universo proposes the necessity of changing the epistemology of apodictic scientific-philosophical knowledge, based on certainty, for the “epistemology of risk”. Furthermore, it suggests a better approach between (...) philosophy and science in order to surpass the confusion and standstill that affect these disciplines today. This paper analyses both matters.

I set out and explore an argument for God's existence based on the idea that the possibility of God requires the existence of God as a ground. After setting this argument out, I compare it to other arguments for God, concentrating on an argument from Descartes's Third Meditation. I then address various objections and conclude by setting out a non-theistic version of the argument.

Epistemic two-dimensional semantics, advocated by Chalmers and Jackson, among others, aims to restore the link between necessity and a priority seemingly broken by Kripke, by showing how armchair access to semantic intensions provides a basis for knowledge of necessary a posteriori truths. The most compelling objections to E2D are that, for one or other reason, the requisite intensions are not accessible from the armchair. As we substantiate here, existing versions of E2D are indeed subject to such access-based objections. But, we (...) moreover argue, the difficulty lies not with E2D but with the typically presupposed conceiving-based epistemology of intensions. Freed from that epistemology, and given the right alternative—one where inference to the best explanation provides the operative guide to intensions—E2D can meet access-based objections, and fulfill its promise of restoring the desirable link between necessity and a priority. This result serves as a central application of Biggs and Wilson, according to which abduction is an a priori mode of inference. (shrink)

Animal replaceability is supposed to be a feature of some consequentialist theories, like Utilitarianism. Roughly, an animal is replaceable if it is permissible to kill it because the disvalue thereby caused will be compensated by the value of a new animal’s life. This is specially troubling since the conditions for such compensation seem easily attainable by improved forms of raising and killing animals. Thus, grounding a strong moral status of animals in such theories is somewhat compromised. As is, consequently, their (...) position as an alternative to rights-based theories in animal ethics. Recognising this, some utilitarians tried to disassociate utilitarianism and replaceability. I will here add my voice to this project. However, instead of seeing the culprit in the usual suspects (hedonism, maximisation or the total view), I advance a new proposal. After identifying that the compensating value for a disvaluable action has to be its consequence, I present a restriction on consequences: consequences of sequences of actions cannot be consequences of the isolated actions in the sequences. Given this, the main argument is simple: killing an animal is permissible only if the the value of the new animal’s life is a consequence of the killing; but this value is a consequence of a sequence of actions which involves the killing plus some additional actions; therefore, since, via the restriction, such value is not a consequence of the killing, it is irrelevant to its normative status. I then present two further motivations for the restriction: firstly, it prevents the value of conditional actions from trivially influencing the value of the actions on which they are conditional; secondly, it is useful – even if not a complete solution – to reply other objections to consequentialism: the accordion effect of action and the cluelessness problem. I finally consider a couple of objections. (shrink)

Speech and thought about what the law is commonly function in practical ways, to guide or assess behavior. These functions have often been seen as problematic for legal positivism in the tradition of H.L.A. Hart. One recent response is to advance an expressivist analysis of legal statements (Toh), which faces its own, familiar problems. This paper advances a rival, positivist-friendly account of legal statements which we call “quasi-expressivist”, explicitly modeled after Finlay’s metaethical theory of moral statements. This consists in a (...) descriptivist, “rule-relational” semantics combined with a pragmatic account of the expressive and practical functions of legal discourse. We argue that this approach is at least as well-equipped as expressivism to explain the motivational and prescriptive features of “internal” legal statements, as well as a fundamental kind of legal disagreement, while being better positioned to account for various “external” uses of the same language. We develop this theory in a Hartian framework, and in the final part of the paper argue (particularly against Toh’s expressivist interpretation) that Hart’s own views in The Concept of Law are best reconstructed along such quasi-expressivist lines.

Timothy Hsiao attempts to defend industrial animal farming by arguing that it is not inherently cruel. We raise three main objections to his defense. First, his argument rests on a misunderstanding of the nature of cruelty. Second, his conclusion, though technically true, is so weak as to be of virtually no moral significance or interest. Third, his contention that animals lack moral standing, and thus that mistreating them is wrong only insofar as it makes one more disposed to mistreat other (...) humans, is untenable on both philosophical and biological grounds.
