Clearing algorithms are at the core of modern payment systems, facilitating the settling of multilateral credit messages with (near) minimum transfers of currency. Traditional clearing procedures use batch processing based on MILP - mixed-integer linear programming algorithms. The MILP approach demands intensive computational resources; moreover, it is also vulnerable to operational risks generated by possible defaults during the inter-batch period. This paper presents TORC3 - the Token-Ring Clearing Algorithm for Currency Circulation. In contrast to the MILP approach, TORC3 is a (...) real time heuristic procedure, demanding modest computational resources, and able to completely shield the clearing operation against the participating agents’ risk of default.

We present a module based criterion, i.e. a sufficient condition based on the absolute value of the matrix coefficients, for the convergence of Gauss–Seidel method (GSM) for a square system of linear algebraic equations, the Generalized Line Criterion (GLC). We prove GLC to be the “most general” module based criterion and derive, as GLC corollaries, some previously know and also some new criteria for GSM convergence. Although far more general than the previously known results, the proof of GLC is simpler. (...) The results used here are related to recent research in stability of dynamical systems and control of manufacturing systems. (shrink)

Apresentaremos neste texto a tese de David Hume sobre a identidade pessoal tal como é apresentada no Tratado da natureza humana, de sua autoria. No apêndice da obra, Hume apresenta dúvidas sobre a tese que defendeu, apontando uma série de problemas que não se resolvem em sua teoria. Mas o tratamento desses problemas e uma possível resposta a Hume podem ser encontrados em D. W. Winnicott.

Este texto puede dividirse en dos secciones: en la primera se expone la filosofía de Hume: los principios que adopta y defiende, y cómo ellos lo han de llevar inevitablemente a sus conclusiones escépticas, en especial acerca de la necesidad de las relaciones causales. En la segunda se examina el lazo que hay entre Hume y Kant, cómo la filosofía del primero da pie para que el segundo comience sus investigaciones críticas o, como él lo llama, permite que “despierte de (...) su sueño dogmático”, y se presenta la progresiva construcción de la respuesta a Hume, por medio del enlace de las distintas partes de la filosofía crítica y la argumentación trascendental, permitiendo así ver su lugar en el todo y su relevancia.

O artigo em questão se detém nas implicações epistemológicas da revolução copernicana de Immanuel Kant, cuja perspectiva, emergindo das fronteiras que inter-relacionam o racionalismo de Leibniz, o empirismo de Hume e a ciência positiva físico-matemática de Newton, instaura o horizonte do idealismo transcendental, estabelecendo a correlação fundamental envolvendo o sujeito e o objeto do conhecimento.

Article in question holds in epistemological implications of the revolution copernicana of Immanuel Kant, whose perspective, emerging of borders that inter-related rationalism of Leibniz, empiricism Hume and science positive physical-mathematics Newton, introduces the horizon of idealism transcendental, establish the correlation fundamental involving the subject and object of knowledge.

In this paper we don’t intend to show, against the sceptic, that most of our everyday beliefs about the external world are cases of knowledge. What we do try to show is that it is more rational to hold that most of such beliefs are actually cases of knowledge than to deny them this status, as the external world sceptic does. In some sense, our point of view is the opposite of Hume’s, who held that reason clearly favours scepticism about (...) the independent existence of an external world rather than common sense belief in such an independent existence. In arguing for the superior rationality of this common sense, Moorean view, we also take a fallibilist conception of knowledge to be rationally preferable to an infallibilist view of it. (shrink)

It is part of an old folklore that logic should not have existential theo- rems or existential validities. One should not prove in pure logic the existence of anything whatsoever; nothing could be proved by means of logic alone to necessarily exist. Whatever exists might not exist. This standpoint has been expressed by several philosophers from different traditions, such as Hume, Kant, Orenstein and Quine. We now set the stage by examining some issues. Our main question is: “Do we actually (...) have existential theorems in logic?” Two possible attitudes towards this question are as follows. A desideratum: logic should not have any existential theorems. A fact: logic does not have any existential theorems. (shrink)

The complex world of thought and sensitivity in the sphere of contemporary art has entailed the revision and exclusion of disciplines aimed at providing a model to explain and conceptualize reality. Art history, as one such discipline, has had many of its contributions questioned from Gombrich’s epistemological reformulation to the postmodern discourses, which extol the death of the author, the post-structuralist idea of tradition as a textual phenomenon, and the declaration of the death of history as a consequence of the (...) hybridization of disciplines and of other bran- ches of human knowledge. Nevertheless, it can be demonstrated that proposals as those by Julius von Schlosser and Giulio Carlo Argan enclose reflections and methodological aspects which can help us face the task of understanding and visualizing the mediating role of historians in the culture of sensitivity, and the art modulations that have resulted from the blows of history and that, in turn, have shaped both art and art history into what they are or can be to us today.

Phenomenal qualities are embodied spaciotemporal abstractions subjectively perceived by a conscious observer. Specific examples, i.e., qualia, include the color purple, the taste of chocolate, and the fragrance of a rose. The question of whether phenomenal awareness can be empirically understood forms one important facet of the “Hard Problem of Consciousness” (Chalmers, 1995, pp. 200–219). It is the position of this analysis that we will never understand why we experience sensory qualities in the manner we do until we first comprehend how (...) they may have evolved in the very distant past. This examination explores the evolutionary development of phenomenal experience. In so doing, it proposes that behind the mechanisms through which external stimuli interface with our sensory apparatus, there lies a long evolutionary process of standardization, approximation, and synchronization that has ultimately forged the close links between the two. The consistent and efficient correlations that the resultant evolutionary links give rise to cumulatively generate conscious experience. There is a tight correspondence between our sensations and incoming stimuli, and this synchronous covariance is meaningful and functional; however, it does not result from a strict cause-and-effect relationship between the physical properties of external objects and our internal neurophysiology. As such, this investigation endorses Hoffman’s (1998, 2003, 2008, 2009) view that the external world is largely hidden from direct sensory evaluation. The following inquiry utilizes Jung’s (1952) “Acausal Connecting Principle” to further explore the concept of complementary sensory phenomena as it may have originally been envisioned by Wolfgang Pauli. (Meier, 2001) This thesis, with respect to meaningful acausality and synchronicity, is first used to provide a plausible explanation for the initial genetic development of color perception, and then employed to examine the analogous evolutionary ties that ultimately engender all sensory modalities. Without invoking the Quantum-Mind hypothesis, this paper supports the idea that our five senses are not direct, or true, or even approximate abstract representations of any underlying material properties of incoming stimuli; instead, they efficiently provide useful higher-order assumptions pertaining to the macro properties of spacetime, matter, and motion, as well as the causal-objective of all life. The overall investigation concludes that it is the structural categorization, hierarchical organization, and qualitative characterization of this indirect presumptive meta-information that has engendered meaningful sensory experience, and all conscious thought over evolutionary time.

A hundred years ago, Ramsey (1927) devised a new system of notation to more perspicuously represent the idea that ‘p’ and ‘¬¬p’ express the same fact. Recently, Monroy Pérez (2023) has argued that we can apply Ramsey’s insight to solve a recalcitrant problem for logical elitism — the thesis, most famously defended by Sider (2011), that the world’s fundamental metaphysical structure includes logical structure. Here, I discuss the general role of language in the framing of logical elitism and present four (...) arguments that show that the Ramseyan strategy for defending logical elitism fails. First, it does not eliminate all arbitrariness even for zeroth-order classical logic (§3). Second, it is a case of a more general strategy that exploits the fact that classical negation is an involution; then, choosing the Ramseyan proposal among the other cases is arbitrary (§4). Third, there are proposals to solve the riddle that are simpler than every case of the involutory strategy (§5). The discussion has consequences for logical elitism at large: in my fourth argument I contend, contrary to a fairly favoured opinion, that logical elitism should not be thought of as a thesis about languages, but as a thesis about joints in metaphysical structure (§6).

Minding Time: A Philosophical and Theoretical Approach to the Psychology of Time offers an innovative philosophical account of the most fundamental kinds of time representation.

This paper explores the scope and limits of rational consensus through mutual respect, with the primary focus on the best known formal model of consensus: the Lehrer–Wagner model. We consider various arguments against the rationality of the Lehrer–Wagner model as a model of consensus about factual matters. We conclude that models such as this face problems in achieving rational consensus on disagreements about unknown factual matters, but that they hold considerable promise as models of how to rationally resolve non-factual disagreements.

One challenge faced by aesthetics is the development of an account able to trace out the continuities and discontinuities between general experience and aesthetic experiences. Regarding this issue, in this paper, I present an enactive model of some raw cognitive dynamics that might drive the progressive emergence of aesthetic experiences from the stream of general experience. The framework is based on specific aspects of John Dewey’s pragmatist philosophy and embodied aesthetic theories, while also taking into account research in ecological psychology, (...) cognitive sciences, and dynamic systems theory. The model focuses on dynamically relevant nodes at the pre-reflective and the reflective side of experience that would work as nested rhythmic constraints at different cognitive timescales with the potential to shunt experiences toward the aesthetic in everyday situations. My proposal constitutes a way to explore aesthetic experiences from an enactive perspective that regards them as transformative events in which cognitive processes entrain and are entrained by changes taking place in the environment, the brain, and the body.

Some metaphysicians believe that metaphysical modality is explainable by the essences of objects. In §II, I spell out the definitional view of essence, and in §III, a working notion of metaphysical explanation. Then, in §IV, I consider and reject five natural ways to explain necessity by essence: in terms of the principle that essential properties can't change, in terms of the supposed obviousness of the necessity of essential truth, in terms of the logical necessity of definitions, in terms of Fine's (...) logic of essence, and in terms of the theory of real definitions. I will conclude that the present evidence favours rejecting the hypothesis that modality is explainable by essence. (shrink)

In this paper I offer a defence of a Russellian analysis of the referential uses of incomplete (mis)descriptions, in a contextual setting. With regard to the debate between a unificationist and an ambiguity approach to the formal treatment of definite descriptions (introduction), I will support the former against the latter. In 1. I explain what I mean by "essentially" incomplete descriptions: incomplete descriptions are context dependent descriptions. In 2. I examine one of the best versions of the unificationist “explicit” approach (...) given by Buchanan and Ostertag. I then show that this proposal seems unable to treat the normal uses of misdescriptions. I then accept the challenge of treating misdescriptions as a key to solving the problem of context dependent descriptions. In 3. I briefly discuss Michael Devitt’s and Joseph Almog’s treatments of referential descriptions, showing that they find it difficult to explain misdescriptions. In 4. I suggest an alternative approach to DD as contextuals, under a normative epistemic stance. Definite descriptions express (i) what a speaker should have in mind in using certain words in a certain context and (ii) what a normal speaker is justified in saying in a context, given a common basic knowledge of the lexicon. In 5. I define a procedure running on contextual parameters (partiality, perspective and approximation) as a means of representing the role of pragmatics as a filter for semantic interpretation. In 6. I defend my procedural approach against possible objections concerning the problem of the boundaries between semantics and pragmatics, relying on the distinction between semantics and theory of meaning.

This article develops a fairness-based criticism of the UK’s policy of promoting free admissions at major museums. With a focus on geographic inequalities and per-capita museums spending, I argue that free admissions can be a surprisingly bad way of promoting cultural opportunities for disadvantaged groups. My criticism emphasises the fact that free admissions consume resources without necessarily providing targeted benefits to disadvantaged groups and addressing background inequalities. Given that museums vary in their location, visitor profile, and operating costs, this critique (...) does not apply to all museums. It applies to the largest and most popular museums in the most advantaged areas, which can expect to keep drawing significant numbers while charging. If we are aiming to prioritise the interests of less advantaged groups, we should be in favour of charging at London’s major museums, to finance “levelling up” across regions, and more direct access-promoting measures in targeted outreach, collaboration, and programming.

The project of growing meat artificially represents for some the next best thing to humanity. If successful, it could be the solution to several problems, such as feed- ing a growing global population while reducing the environmental impact of raising animals for food and, of course, reducing the amount and degree of animal cruelty and suffering that is involved in animal farming. In this paper, I argue that the issue of the morality of such a project has been framed only (...) in terms of the best conse- quences for the environment, animals, and humans, or in terms of deontic princi- ples. I argue that to appreciate how deep and difficult this issue is, it is necessary to consider it in terms of a virtue-oriented approach. Such an approach will reveal aspects that are not apparent, not contemplated by typical approaches, but are essen- tial to our understanding of the morality of lab-grown meat. As I argue, evaluating the issue from a virtue-oriented perspective suggests that the project of in vitro meat should not be supported because it stems from unvirtuous motivations. (shrink)

The frame problem, a long-standing issue in Artificial Intelligence (AI), revolves around determining the relevance of information in an ever-changing array of contexts, posing a formidable challenge in modeling human reasoning. The purpose of this paper is to explore the hypothesis that emotions are able to solve, or at least enable a substantial step towards a solution. I argue that, while emotions are integral to cognitive processes, they do not offer a solution to the frame problem, nor can they play (...) a significant role in a solution. In the course of the argument, I’ll show why some previous claims that emotions could be helpful towards a solution rely on a problematic analysis of what the frame problem is. Ultimately, the conclusion is that no context-dependent feature can play a non-trivial role in solutions to the frame problem, and that is the case of emotions. (shrink)

Abstract Nowadays, there is a deep and widespread feeling of discomfort among academics due to the psychological and labor pressures that universities exert upon their researchers by demanding endless publications. In this paper, I offer numerous pieces of evidence of this crisis, which affects primarily those who inhabit academic ecologies. First, I argue that it is convenient to understand the current situation as an expression of technologies and individual apparatuses shaped by subjectivizing ideologies, and mechanisms of exclusion, stigmatization, and replacement. (...) Second, I examine two proposals against the crisis produced by the pace of academic production framed by the Slow movement. Lastly, after making explicit some of the assumptions that undergird the university’s epistemological machine, I propose to complement Ulmer and Mountz’s project with two suggestions. On the one hand, I extend an invitation to reflect on and with students as a means to redirect the university’s teleology. On the other hand, I suggest incorporating an ontogogic approach as a resistance apparatus against the pressure from the university’s production machine. The article’s point of departure is anti-dicotonegative because it is based on a summative approach rather than in an agonistic procedure. In other words, I propose two additional tools that can be put to the test to contribute to solving the university publication crisis. (shrink)

On the basis of historical and textual evidence, this paper claims that after his Tractatus, Wittgenstein was actually influenced by Einstein's theory of relativity and, the similarity of Einstein's relativity theory helps to illuminate some aspects of Wittgenstein's work. These claims find support in remarkable quotations where Wittgenstein speaks approvingly of Einstein's relativity theory and in the way these quotations are embedded in Wittgenstein's texts. The profound connection between Wittgenstein and relativity theory concerns not only Wittgenstein's “verificationist” phase , but (...) also Wittgenstein's later philosophy centred on the theme of rule‐following.

Many moral philosophers have criticized intensive animal farming because it can be harmful to the environment, it causes pain and misery to a large number of animals, and furthermore eating meat and animal-based products can be unhealthful. The issue of industrially farmed animals has become one of the most pressing ethical questions of our time. On the one hand, utilitarians have argued that we should become vegetarians or vegans because the practices of raising animals for food are immoral since they (...) minimize the overall happiness. Deontologists, on the other hand, have argued that the practices of raising animals for food are immoral because animals have certain rights and we have duties toward them. Some virtue ethicists remain unconvinced of deontic and consequentialist arguments against the exploitation of animals and suggest that a virtue-based approach is better equipped to show what is immoral about raising and using animals for food, and what is virtuous about ethical veganism.

Jean-François Lyotard s'interroga sulla forma delle organizzazioni sociali e ne identifica la problematica principale nell'eterogeneità che esse veicolano tra i differenti regimi di frasi: si sofferma, in particolare, sull'incompatibilità tra il regime della conoscenza e quello della libertà. A partire da tale riflessione, l'articolo esamina come le società attuali, multiculturali e globalizzate, siano chiamate oggi a compiere una scelta: abbracciare la sintesi dell'eterogeneo oppure rispettare e far rispettare la presenza inevitabile del dissidio. Nella prima occorrenza si corre il rischio di (...) trasformare il diritto in succedaneo dell'ordalia e di accendere la guerra di tutti contro tutti. Nella seconda, invece, si sperimenta la costruzione d'interazioni di tipo dipolare le quali, pur non potendo garantire contro lo scatenamento smisurato della violenza, riescono potenzialmente ad arginarlo. Queste ultime, infatti, spostano la misura della sopravvivenza dall'esclusione delle ostilità alla loro elusione, dal rifiutare il conflitto all'addomesticarlo, dal rinunciare allo sforzo muscolare al calibrarlo.

There has been much debate recently on the question whether essence can explain modality. Here, I examine two routes to an essentialist account of modality. The first is Hale's argument for the necessity of essence, which I will argue is — notwithstanding recent attempted defences of it — invalid by its very structure. The second is the proposal that it is essential to essential truth that it is necessary. After offering three possible versions of the view, I will argue that (...) each fails to provide a metaphysical explanation of necessity in terms of essence. (shrink)

In Overlooking Conventions Michael Devitt argues in defence of the traditional approach to semantics. Devitt’s main line of argument is an inference to the best explanation: nearly all cases that linguistic pragmatists discuss in order to challenge the traditional approach to semantics are better explained by adding conventions into language, in the form of expanding the range of polysemy or the range of indexicality (in the broad sense of linguistically governed context sensitivity). In this paper, we discuss three aspects of (...) a draft of Devitt’s Overlooking Conventions, which was discussed at a conference in Dubrovnik in September 2018. First, we try to show that his rejection of Bach’s distinction between convention and standardization overlooks important features of standardization. Second, we elaborate on Devitt’s argument against linguistic pragmatism based on the normative aspect of meaning and show that a similar argument can be mounted against semantic minimalism. While Devitt and minimalists have a common enemy, they are not allies either. Third, we address a methodological difficulty in Devitt’s view concerning a threat of over-generation and propose a solution to it. Although this paper is the result of collaboration the authors have written different parts. Carlo Penco has written part 1, Massimiliano Vignolo has written part 2 and part 3. (shrink)

Despite the widespread presence of public arts funding in liberal societies, some liberals find it unjustified. According to the Neutrality Objection, arts funding preferences some ways of life. One way to motivate this challenge is to say that a public goods-styled justification, although it could relieve arts funding of these worries of partiality, cannot be argued for coherently or is, in the end, too susceptible to impressions of partiality. I argue that diversity-based arts funding can overcome this challenge, because it (...) invests in non-excludable infrastructure that fosters cultural literacy. We all have some interest as citizens in living in a society which fosters cultural literacy, seeing as this helps others to understand us, supports us to understand ourselves, and helps alleviate confusion and alienation we feel toward social difference. While some of these benefits can be enjoyed by those who make and consume art, they are also gained by those who don’t, because arts funding affects the makeup of public spaces and the communicative practices we all use to make sense of the world.

In his paper “What the externalist can know a priori”, Paul Boghossian rejects the compatibility between self-knowledge and content externalism by arguing that compatibilists are committed to the absurd view that a subject can know, by reasoning purely a priori, substantive truths about the world, such as that water exists. In this paper I try to show that Boghossian’s incompatibilist argument does not succeed. According to Boghossian, it is enough, for an externalist to reach the undesired conclusion, that she satisfies (...) a number of conditions that can be known by her a priori. I argue that, by an externalist’s lights, some of these conditions are simply too weak to be acceptable by her and some of them can only be known a posteriori. So, compatibilists are not committed to the absurdity Boghossian ascribes to them. (shrink)

Marcus William Hunt argues that when co-parents disagree over whether to raise their child (or children) as a vegan, they should reach a compromise as a gift given by one parent to the other out of respect for his or her authority. Josh Millburn contends that Hunt’s proposal of parental compromise over veganism is unacceptable on the ground that it overlooks respect for animal rights, which bars compromising. However, he contemplates the possibility of parental compromise over ‘unusual eating,’ of animal-based (...) foods obtained without the violation of animal rights. I argue for zero parental compromise, rejecting a rights-oriented approach, and propose a policy that an ethical vegan parent and a non-vegan co-parent should follow to determine how to raise their children.

In recent decades much literature has been produced on disagreement; the puzzling conclusion being that epistemic disagreement is, for the most part, either impossible (e.g. Aumann (Ann Stat 4(6):1236–1239, 1976)), or at least easily resolvable (e.g. Elga (Noûs 41(3):478–502, 2007)). In this paper I show that, under certain conditions, an equally puzzling result arises: that is, disagreement cannot be rationally resolved by belief updating. I suggest a solution to the puzzle which makes use of some of the principles of Hintikka’s (...) Socratic epistemology. (shrink)

In this paper I address the question whether self-knowledge is compatible with an externalist individuation of mental content. Against some approaches, I consider self-knowledge as a genuine cognitive achievement. Though it is neither incorrigible nor infallible, self-knowledge is direct, a priori (no based on empirical investigation), presumptively true and authoritative. The problem is whether self-knowledge, so understood, is compatible with externalism. My answer will be affirmative. I will defend this species of compatibilism against several objections, in particular those based on (...) the possibility of an individual’s being unwittingly switched between worlds. (shrink)

According to the Principle of Alternative Possibilities, an agent is morally responsible for an action of hers only if she could have done otherwise. The notion of a robust alternative plays a prominent role in recent attacks on PAP based on so-called Frankfurt cases. In this paper I defend the truth of PAP for blameworthy actions against Frankfurt cases recently proposed by Derk Pereboom and David Widerker. My defence rests on some intuitively plausible principles that yield a new understanding of (...) the concept of a robust alternative.

Carlos Pereda's "Mexico Unveiled" is a fresh, idiosyncratic synthesis of twentieth-century Mexican philosophy that puts contemporary debates about Mexican identity politics into a critical perspective. In three engaging essays written in a peerless prose style, Pereda considers the persistent influence of European colonialism on Mexican intellectual life, the politics of inclusion, and the changing ideas of what it means to be Mexican. He identifies three "vices"—social habits, customs, and beliefs inherited from European colonialism—that have influenced the development of Mexican (...) national identity: subaltern fervor, craving for novelty, and nationalist zeal. Pereda demonstrates that these three tendencies have led Mexican intellectuals, and Mexican society more generally, to uncritically adopt a politics of exclusion and destructive nationalist attitudes. To do all of this, Pereda invites readers to follow him along as he explores an often surprising series of arguments and counterarguments. Using a strategy he calls "nomadic" thinking—the act of moving beyond our cultural preconceptions and habits of thinking—he guides readers through a number of examples drawn from Mexican philosophy and culture that illustrate these tendencies. At its core, "Mexico Unveiled" is an accessible and entertaining introduction to the philosophical themes that have long occupied Pereda's life and work and Mexican philosophy more generally.

Although the treatise presented here is most interesting, it was never widely disseminated. As far as we know, it is preserved only in Latin, in one manuscript. The text poses many questions. Who produced a copy of the text? Who is the translator? Is the treatise a genuine work of Averroes? And if so, what was his intention in writing this monograph on the First Cause?

The main thesis of this paper is that two prevailing theories about cognitive penetration are too extreme, namely, the view that cognitive penetration is pervasive and the view that there is a sharp and fundamental distinction between cognition and perception, which precludes any type of cognitive penetration. These opposite views have clear merits and empirical support. To eliminate this puzzling situation, we present an alternative theoretical approach that incorporates the merits of these views into a broader and more nuanced explanatory (...) framework. A key argument we present in favor of this framework concerns the evolution of intentionality and perceptual capacities. An implication of this argument is that cases of cognitive penetration must have evolved more recently and that this is compatible with the cognitive impenetrability of early perceptual stages of processing information. A theoretical approach that explains why this should be the case is the consciousness and attention dissociation framework. The paper discusses why concepts, particularly issues concerning concept acquisition, play an important role in the interaction between perception and cognition. (shrink)

En este artículo presentamos el modelo tradicional (que llamaremos canónico) que se ha usado para explicar el autoengaño y algunos de los problemas que ha de enfrentar. Presentaremos luego el que ha sido conocido como el modelo deflacionista o no intencionalista y defenderemos que es una alternativa mejor para entender este fenómeno que el modelo canónico. Finalmente, presentaremos una limitación o problema que ha de enfrentar el modelo deflacionista y que, al ser tratada, obliga a hacer ciertas consideraciones y a (...) mirarlo bajo una nueva luz que, lejos de ponerlo en duda o debilitarlo, termina por fortalecerlo.

En cada una de las secciones de este texto acudiremos a ejemplos de la literatura que sirven para presentar con claridad las características de cada caso. (shrink)

The philosophical conception of mechanistic explanation is grounded on a limited number of canonical examples. These examples provide an overly narrow view of contemporary scientific practice, because they do not reflect the extent to which the heuristic strategies and descriptive practices that contribute to mechanistic explanation have evolved beyond the well-known methods of decomposition, localization, and pictorial representation. Recent examples from evolutionary robotics and network approaches to biology and neuroscience demonstrate the increasingly important role played by computer simulations and mathematical (...) representations in the epistemic practices of mechanism discovery and mechanism description. These examples also indicate that the scope of mechanistic explanation must be re-examined: With new and increasingly powerful methods of discovery and description comes the possibility of describing mechanisms far more complex than traditionally assumed.

Abstract: This paper is a response to Park Seungbae’s article, “Defence of Cultural Relativism”. Some of the typical criticisms of moral relativism are the following: moral relativism is erroneously committed to the principle of tolerance, which is a universal principle; there are a number of objective moral rules; a moral relativist must admit that Hitler was right, which is absurd; a moral relativist must deny, in the face of evidence, that moral progress is possible; and, since every individual belongs to (...) multiple cultures at once, the concept of moral relativism is vague. Park argues that such contentions do not affect moral relativism and that the moral relativist may respond that the value of tolerance, Hitler’s actions, and the concept of culture are themselves relative. In what follows, I show that Park’s adroit strategy is unsuc-cessful. Consequently, moral relativism is incoherent. (shrink)

In this paper, I will discuss a well-known oscillation in Frege’s conception of sense. My point is only partially concerned with his two different criteria of sense identity, and touches upon a more specific point: what happens if we apply Frege’s intuitive criterion for the difference of thoughts to logically equivalent sentences? I will try to make a schematic argument here that will preempt any endeavor to make Frege more coherent than he really is. In sections A and B, I (...) will present two alternative Fregean ways to treat the sense of logically equivalent sentences. Frege really oscillated between two alternative conceptions of sense, and his inability to detect the contrast between the two alternative conceptions is partly due to his strong conception of rationality. To apply the criterion of difference of thoughts to logical matters, we may also use a weak notion of rationality, or at least a notion of rationality of human agents, with limited computational resources. The distinctions towards which Frege was striving are better understood nowadays from the point of view of the treatment of limited rationality, which imposes itself even in logical matters.

In this paper I respond to Marcus William Hunt’s argument that vegan parents have pro tanto reasons for not raising their children on a vegan diet because such a diet is potentially harmful to children’s physical and social well-being. In my rebuttal, first I show that in practice all vegan diets, with the exception of wacky diets, are beneficial to children’s well-being ; and that all animal-based diets are potentially unhealthful. Second, I show that vegan children are no more socially (...) outcast than any other group. In other words, veganism does not harm the lives of children. Having considered several studies, I show that the moral reasons that vegan parents may have for raising their children on a vegan diet significantly outweigh the reasons for raising their children on an animal-based diet. Thus, I conclude that parents have a moral obligation to raise their children on a vegan diet. (shrink)

Is it possible to know anything about life we have not yet encountered? We know of only one example of life: our own. Given this, many scientists are inclined to doubt that any principles of Earth’s biology will generalize to other worlds in which life might exist. Let’s call this the “N = 1 problem.” By comparison, we expect the principles of geometry, mechanics, and chemistry would generalize. Interestingly, each of these has predictable consequences when applied to biology. The surface-to-volume (...) property of geometry, for example, limits the size of unassisted cells in a given medium. This effect is real, precise, universal, and predictive. Furthermore, there are basic problems all life must solve if it is to persist, such as resistance to radiation, faithful inheritance, and energy regulation. If these universal problems have a limited set of possible solutions, some common outcomes must consistently emerge. In this chapter, I discuss the N = 1 problem, its implications, and my response (Mariscal 2014). I hold that our current knowledge of biology can justify believing certain generalizations as holding for life anywhere. Life on Earth may be our only example of life, but this is only a reason to be cautious in our approach to life in the universe, not a reason to give up altogether. In my account, a candidate biological generalization is assessed by the assumptions it makes. A claim is accepted only if its justification includes principles of evolution, but no contingent facts of life on Earth. (shrink)

On a highly influential way to think of modality, that I call ‘relationalism’, the modality of a state is explained by its being composed of properties, and these properties being related by a higher-order and primitively modal relation. Examples of relationalism are the Dretske-Tooley-Armstrong account of natural necessity, many dispositional essentialist views, and Wang’s incompatibility primitivism. I argue that relationalism faces four difficulties: that the selection between modal relations is arbitrary, that the modal relation cannot belong to any logical order, (...) that to explain how the modal relation can relate properties of different adicities additional ideological complexity has to be introduced, and that not all modal constraints are relational. From the discussion, I will extract desiderata for a successor theory of modality. (shrink)

The Whorfian hypothesis has received support from recent findings in psychology, linguistics, and anthropology. This evidence has been interpreted as supporting the view that language modulates all stages of perception and cognition, in accordance with Whorf’s original proposal. In light of a much broader body of evidence on time perception, I propose to evaluate these findings with respect to their scope. When assessed collectively, the entire body of evidence on time perception shows that the Whorfian hypothesis has a limited scope (...) and that it does not affect early stages of time perception. In particular, all the available evidence shows that the scope of language modulation is limited in the case of time perception, and that the most important mechanisms for time perception are cognitive clocks and simultaneity windows, which we use to perceive the temporal properties of events. Language modulation has distorting effects, but only at later stages of processing or with respect to specific categorization tasks. The paper explains what is the role of these effects in the context of all the available evidence on time cognition and perception. (shrink)
