This paper presents an edition of al-Hasan ibn al-asan ibn al-Haytham's treatise, Qawl fi samt al-qibla bi-al-isāb with translation and commentary. In it Ibn al-Haytham provides a universal method for finding the direction of the qibla at any location on the surface of the earth by using spherical trigonometry and accurate calculation. Ibn al-Haytham's computational solution has not been studied before, and it has often been confused with another work of his in which he uses an analemma construction to solve (...) the problem of the qibla graphically. As a result of this confusion, contemporary scholars have mistakenly attributed the first universal solution of the qibla problem to Jamshīd al-Kāshī, some four centuries after the introduction of this method by Ibn al-Haytham. The present treatise represents an important juncture in the history of the development of mathematics of the qibla, and sheds more light on the contributions of one of the most important scientists of medieval Islam.

Kant claims that the nominal definition of truth is: “Truth is the agreement of cognition with its object”. In this paper, I analyse the relevant features of Kant's theory of definition in order to explain the meaning of that claim and its consequences for the vexed question of whether Kant endorses or rejects a correspondence theory of truth. I conclude that Kant's claim implies neither that he holds, nor that he rejects, a correspondence theory of truth. Kant's claim is not (...) a generic way of setting aside a correspondence definition of truth, or of considering it uninformative. Being the nominal definition of truth, the formula “truth is the agreement of cognition with its object” illustrates the meaning of the predicate “is true” and people's ordinary conception of truth. True judgements correspond to the objects they are about. However, there could be more to the property of truth than correspondence. (shrink)

Although the notion of empiricism looms large in many histories of early modern philosophy, its origins are not well understood. This paper aims to shed light on them. It examines the notions of empirical philosopher, physician, and politician that are employed in a range of seventeenth- and eighteenth-century texts, alongside related notions (e.g. "experimental philosophy") and methodological stances. It concludes that the notion of empiricism used in many histories of early modern thought does not have pre-Kantian origins. It first appeared (...) and became widely used in late eighteenth-century Germany, in the course of the early debates on Kant's Critical philosophy. (shrink)

We provide ethical criteria to establish when vaccine mandates for healthcare workers are ethically justifiable. The relevant criteria are the utility of the vaccine for healthcare workers, the utility for patients (both in terms of prevention of transmission of infection and reduction in staff shortage), and the existence of less restrictive alternatives that can achieve comparable benefits. Healthcare workers have professional obligations to promote the interests of patients that entail exposure to greater risks or infringement of autonomy than ordinary members (...) of the public. Thus, we argue that when vaccine mandates are justified on the basis of these criteria, they are not unfairly discriminatory and the level of coercion they involve is ethically acceptable—and indeed comparable to that already accepted in healthcare employment contracts. Such mandates might be justified even when general population mandates are not. Our conclusion is that, given current evidence, those ethical criteria justify mandates for influenza vaccination, but not COVID-19 vaccination, for healthcare workers. We extend our arguments to other vaccines. (shrink)

In considering the possibility that the fundamental particles of matter might violate Leibniz's Principle, one is confronted with logical proofs that the Principle is a Theorem of Logic. This paper shows that the proof of that theorem is not universal enough to encompass entities that might not be unique, and also strongly suggests that photons, for example, do violate Leibniz's Principle. It also shows that the existence of non-individuals would imply the breakdown of Quine's criterion of ontological commitment.

According to Crane’s schematicity thesis (ST) about intentional objects, intentionalia have no particular metaphysical nature qua thought-of entities; moreover, the real metaphysical nature of intentionalia is various, insofar as it is settled independently of the fact that intentionalia are targets of one’s thought. As I will point out, ST has the ontological consequence that the intentionalia that really belong to the general inventory of what there is, the overall domain, are those that fall under a good metaphysical kind, i.e., a (...) kind such that its members figure (for independent reasons) in such an inventory. Negatively put, if there are no things of a certain metaphysical kind, thoughts about things of that kind are not really committed to such things. Pace Crane, however, this does not mean that the intentionalia that are really there are only those that exist. For existence, qua first-order property, is no metaphysical kind. Thus, there may really be intentionalia that do not exist, provided that they belong to good metaphysical kinds. (shrink)

The first half of this article follows Mario Bunge’s early realist moves, his efforts to articulate the achievements of theoretical physics as gains in the quest for objective truth and understanding, particularly in the context of the fights against the idealist and subjectivist interpretations of quantum mechanics that, at least until the mid-1970s, prevailed in physics. Bunge’s answers to the problems of quantum mechanics provide a good angle for understanding how his realist positions grew on the “battlefield.” The second half (...) discusses Bunge’s general conception of the scientific realist stance and confronts it with some current approaches to realism in the mainstream literature.

Many theories of racism presuppose that ordinary usage of the term “racism” should be preserved. Rarely is this presupposition—the presumption of conservatism—defended. This paper discusses the work of Lawrence Blum, Joshua Glasgow, Jorge Garcia, Tommie Shelby, and others, in order to develop a critique of the presumption of conservatism. Against this presumption, I defend the following desideratum: If ordinary usage of “racism” prompts significant practical difficulties that can be averted by revising ordinary usage, then this counts as a mark against (...) the normative status of ordinary usage and so counts as a reason for revising it. The significance of this argument is that it clears the way for a rigorous defense of revisionism. My paper provides a prima facie case for revisionism, built on two practical criticisms of the ordinary usage of “racism.” First, ordinary usage reflects incompatible norms that promote conceptual confusion and misunderstanding, among other problems. Second, ordinary usage reflects an individualistic conception of racism that serves the interests of whites. By championing ordinary usage in our philosophical theories, we (unwittingly) promote the interests of whites over nonwhites. (shrink)

A completeness theorem is established for logics with congruence endowed with general semantics (in the style of general frames). As a corollary, completeness is shown to be preserved by fibring logics with congruence provided that congruence is retained in the resulting logic. The class of logics with equivalence is shown to be closed under fibring and to be included in the class of logics with congruence. Thus, completeness is shown to be preserved by fibring logics with equivalence and general semantics. (...) An example is provided showing that completeness is not always preserved by fibring ligics endowed with standard (non general) semantics. A categorial characterization of fibring is provided using coproducts and cocartesian liftings. (shrink)

El objetivo de este artículo es clarificar la noción de «vida auténtica» tal y como es descrita por Joan Roura-Parella en su última obra Tema y variaciones de la personalidad (1950). Por «vida auténtica» se entiende una vida autogobernada, que permite al individuo realizar su propia singularidad y, por tanto, preservar su autonomía y dignidad como persona. Una vida dominada por factores ajenos al propio individuo, sean cuales sean éstos, es una vida alienada, que no permite el desarrollo del individuo (...) en tanto la persona que es. Se señala la relevancia filosófica de la propuesta de Roura-Parella, que es la de ofrecer una justificación no-evidencial para una forma de vida cristiana, agapística. De acuerdo con Roura-Parella, una forma de vida basada en la entrega amorosa para con el prójimo está justificada en tanto que ésta es el resultado último de nuestra propia condición natural, constituyendo así un acto de afirmación personal y siendo, por tanto, condición necesaria para gozar de una vida auténtica — «la vida alcanza su hondo sentido al salirse de sí misma para darse a los demás» (Roura-Parella, Tema y variaciones de la personalidad, 1950, p. 229). Se señalan las diferencias y semejanzas de la propuesta de Roura-Parella con respecto a las de Miguel de Unamuno y Joaquim Xirau, autores que fueron cercanos a Roura-Parella y quienes, aunque partiendo de razonamientos distintos a los de Roura-Parella, también concibieron la entrega amorosa para con el prójimo como un acto de afirmación personal.

As early as the ninth century, Muslim astronomers started refining the Ptolemaic astronomy which, by this time, had been fully adopted as the framework of their research. Already, in the early part of this century, refinements were based on improved observational techniques, and included a variety of phenomena such as the length of the seasons, the solar equation, mean motion parameters, and many others.

This study provides a detailed description of ways in which Muslim astronomers handled the Greek astronomical legacy, reassessed its cultural and philosophical implications in light of their religiously-inspired world view, and proposed to modify it.

The definition of love given by Descartes in the Passions of the Soul has never stopped puzzling commentators. If the first Cartesian textbooks discreetly evoke or even fail to discuss Descartes’s account of love, Spinoza harshly criticizes it, pointing out that it is ‘on all hands admitted to be very obscure’. More recently several scholars have noticed the puzzling character of the articles of the Passions of the Soul on love and hate. In this paper, I would like to propose (...) a reassessment of the definition of love provided by the Passions of the Soul and the Letters to Elisabeth and Chanut. By tracing back Descartes’s scholastic sources, I will demonstrate how Descartes builds up his definition of love by displacing or subverting the meaning of several major elements of the thomistic vulgata on love. Hence, a significant part of the obscurity of the definition given by the Passions of the Soul possibly finds its ultimate rationale in this attempt to recover some traditional questions of the scholastic debate on love, while advancing new answers to them.

In this contribution, the author contends that the way in which Pieter Lemmens interprets the transcendental of technology, particularly through the work of Bernard Stiegler, is only one of the possible ways of understanding the transcendental of technology. His thesis is that there are many other transcendentals of technology besides technology itself. The task of a philosophy of technology beyond the empirical turn could precisely consist in exploring these multiple transcendentals of technology, along with their multiple relations. In the first (...) section, the author considers and criticizes the “empirical transcendentality” that characterizes most of the current philosophical approaches to technology, in particular when it comes to ethical issues. In the second section, he proposes to include Lemmens’ perspective in a more general theory about the transcendentals of technology. The transcendentals of technology include social symbolic forms, culture, language, media, and many other dimensions that philosophy of technology has not systematically explored yet. (shrink)

We argue that we should provide extra payment not only for extra time worked but also for the extra risks healthcare workers (and those working in healthcare settings) incur while caring for COVID‐19 patients—and more generally when caring for patients poses them at significantly higher risks than normal. We argue that the extra payment is warranted regardless of whether healthcare workers have a professional obligation to provide such risky healthcare. Payment for risk would meet four essential ethical requirements. First, assuming (...) healthcare workers do not have a professional obligation to take on themselves the risks, payments in the form of incentives would preserve autonomy in deciding what risks to take on oneself. Second, even assuming that healthcare workers do have a professional obligation to take on themselves the risks, payments for risk would create fair working conditions by avoiding exploitation. Third, payments for risk would make it more likely that public healthcare systems can discharge their institutional responsibility to provide healthcare in circumstances where healthcare workers may otherwise (perhaps legitimately) opt out. Fourth, payments for risk would guarantee an efficient healthcare system in pandemic situations. Finally, we address two likely objections that some might raise against our proposal, particularly with regard to incentives, namely that such payments or incentives can themselves be coercive and that they represent a form of undue inducement.

This note makes a contribution to the issue raised in a paper by Popper and Miller (1983) in which it was claimed that probabilistic support is purely deductive. Developing R. C. Jeffrey's remarks, a new general approach to the crucial concept of "going beyond" is here proposed. By means of it a quantitative measure of the inductive component of a probabilistic inference is reached. This proposal leads to vindicating the view that typical predictive probabilistic inferences by enumeration and analogy are (...) purely inductive. (shrink)

In this paper I want to show that the idea supporters of traditional creationism (TC) defend, that success of a fictional character across different works has to be accounted for in terms of the persistence of (numerically) one and the same fictional entity, is incorrect. For the supposedly commonsensical data on which those supporters claim their ideas rely are rather controversial. Once they are properly interpreted, they can rather be accommodated by moderate creationism (MC), according to which fictional characters arise (...) out of a reflexive stance on a certain make-believe process. For MC, success of a fictional character across different works amounts to the fact that, first, different work-bound ficta are related with each other by means of a relation weaker than numerical identity, transfictional sameness, and second, that all those ficta are related by transfictional inclusion to a fictum that in some sense gather them all, the so-called general character. Since a general character is an abstract constructed entity, moreover, the more those particular ficta are generated, the more general fictional characters including all of them arise. (shrink)

In this paper, I will present several interpretations of Brentano’s notion of the intentional inexistence of a mental state’s intentional object, i.e., what that state is about. I will moreover hold that, while all the interpretations from Section 1 to Section 4 are wrong, the penultimate interpretation that I focus in Section 5, the one according to which intentional inexistence amounts to the individuation of a mental state by means of its intentional object, is correct provided that it is nested (...) into the really right interpretation, the final one I give in Section 6. For it provides one of the merely necessary conditions of this latter interpretation. According to this final interpretation,intentional inexistence amounts to the constitution of a mental state by means of its intentional object. Finally, I will hold that both such interpretations preserve the idea, which strikes everyone as true, that an intentional object exists in the mental state aboutit pretty much as a pictorial character exists in the picture (qua interpreted entity) that depicts it.

In this paper I argue for a syncretistic theory of depiction, which combines the merits of the main paradigms which have hitherto faced themselves on this issue, namely the perceptualist and semioticist approaches. The syncretistic theory indeed takes from the former its stress on experiential factors and from the latter its stress on conventional factors. But the theory is even more syncretistic than this, for the way it accounts for the experiential factor vindicates several claims defended by different perceptualist theories. (...) In a nutshell, according to the syncretistic theory a picture depicts its subject iff i) it is transformed into an entity-cum-meaning and ii) one has the twofold experience of seeing that subject in the picture qua noninterpreted entity, the image, just in case one consciously misrecognizes it in consciously seeing that image, for that subject resembles the image in some grouping properties (originally labelled Gestalt-qualities in psychology). By appealing to objective resemblance in grouping properties, the theory can vindicate what are nowadays taken to be the most neglected doctrines in the perceptualist camp: objective resemblance theories. By appealing, moreover, to conscious misrecognition, the theory not only squares with both the seeing-in and the recognition theories of depiction, but it also shows the grain of truth in illusion theories of depiction, since conscious misrecognition is a kind of perceptual illusion.

The scientific literature on Wigner’s Friend extended paradox rapidly grew in the last years. A sign that Frauchiger and Renner (2018)’s argument caught an important point. Indeed, they conclude that either we must abandon the universal validity of quantum mechanics, or a certain kind of traditional objective knowledge is impossible. We investigate this contradiction through a logico-epistemic toolbox. We show that abandoning the transmissibility of knowledge, as proposed by many kinds of relational approaches to quantum mechanics, is a heavy epistemological (...) renouncement. Perhaps, it is better to bite the bullet and accept Frauchiger and Renner’s contradiction, until a new revolutionary solution will appear. (shrink)

Focusing especially on Science and the Modern World, this article explores Whitehead's understanding of the social contexts and repercussions of mathematical and scientific abstraction. It investigates his remarks on the need to offset pernicious practices of abstraction in the context of a renewed concern with the link between conceptuality and materiality in social theory. Whitehead's inquiry into the problematic legacy of Galileo and scientific materialism is then contrasted with a different diagnosis of the abstractive maladies of modern society, the one (...) put forward under the Marxist rubric of `real abstraction'. While both stances allow us to explore the social repercussions of abstractive practices, it is argued that an understanding of the practically abstract character of capitalism permits us to identify the limits of Whitehead's pedagogical wish to reform our culture of abstraction.

A common assumption in non-relativistic quantum mechanics is that self-adjoint operators mathematically represent properties of quantum systems. Focusing on spin, we argue that a natural view considers observables as determinable properties and their eigenvalues as their corresponding determinates. We provide a taxonomy of the different views that one can hold, once it is accepted that spin can be modelled with the determinable-determinate relation. In particular, we present the two main families of views, dubbed Spin Monism and Pluralism, and we show (...) that the current literature does not take a stance between the two. Then we put forward two arguments in favour of the former. Finally, we present a new account of Spin Monism, that is absent in current literature; such a view is worth discussing, or so we contend, because several compelling considerations support it, and it opens new ways of thinking about the ontology of quantum mechanics.

We investigate the uniform computational content of the open and clopen Ramsey theorems in the Weihrauch lattice. While they are known to be equivalent to $\mathrm {ATR_0}$ from the point of view of reverse mathematics, there is not a canonical way to phrase them as multivalued functions. We identify eight different multivalued functions and study their degree from the point of view of Weihrauch, strong Weihrauch, and arithmetic Weihrauch reducibility. In particular one of our functions turns out to be strictly (...) stronger than any previously studied multivalued functions arising from statements around $\mathrm {ATR}_0$. (shrink)

In this essay, we aim at framing the ‘negative emotion’ of indifference, starting from its diachronic declination, which seems to beneficiate from a form of justification from the moral point of view (§1). In order to prevent indifference as an outcome – together with its intrinsic motivational strength –, we introduce a methodological account to frame the struggle of motivation internal to the single agent, by classifying different forms of ‘reasons to act’ (§2). We will develop a two-move strategy. Firstly, (...) we deploy what we could call a positive emotion – the sense of solidarity diachronically understood – against that negative one, in order to show that indifference is not the sole possible destination for the humankind (§3). Secondly, to integrate and strengthen the motivational role of that positive emotion, we will rehabilitate a moral approach aimed at setting up a unique normative linkage among generations, by reshaping the interplay between ‘wide’ and ‘narrow obligations’ presented by Kant (§4). The ultimate goal is to contrast the moral strength which is offered by indifference as negative emotion by articulating a motivational path devoted at legitimizing the diachronic moral commitment and duties of justice among generations.

The Australian Federal Government has announced a two-year trial scheme to compensate living organ donors. The compensation will be the equivalent of six weeks paid leave at the rate of the national minimum wage. In this article I analyse the ethics of compensating living organ donors taking the Australian scheme as a reference point. Considering the long waiting lists for organ transplantations and the related costs on the healthcare system of treating patients waiting for an organ, the 1.3 million AUD (...) the Australian Government has committed might represent a very worthwhile investment. I argue that a scheme like the Australian one is sufficiently well designed to avoid all the ethical problems traditionally associated with attaching a monetary value to the human body or to parts of it, namely commodification, inducement, exploitation, and equality issues. Therefore, I suggest that the Australian scheme, if cost-effective, should represent a model for other countries to follow. Nonetheless, although I endorse this scheme, I will also argue that this kind of scheme raises issues of justice in regard to the distribution of organs. Thus, I propose that other policies would be needed to supplement the scheme in order to guarantee not only a higher number of organs available, but also a fair distribution. (shrink)

Clinical ethics consultation has become an integral part of healthcare, serving as a mechanism to navigate complex moral dilemmas that arise in medical practice. The critical dialogue method, as described by Delany et al 1, presents a structured approach that emphasises the role of dialogue in resolving ethical issues. This method is designed to enhance moral clarity and confidence among healthcare professionals, thus improving clinical decision-making. The following commentary delves into the practical application of the critical dialogue method’s seven facilitation (...) steps, analysing real-world cases to illustrate its effectiveness and identifying potential challenges, particularly in culturally diverse settings. The critical dialogue method is structured around seven facilitation steps that steer the ethical deliberation process. These steps are intended to foster a systematic and reflective discussion, prompting participants to consider diverse perspectives and work towards a consensus on ethical matters. The seven steps,1 initiation of dialogue,2 exploration of perspectives,3 identification of ethical principles,4 deliberation on options,5 consensus building, (6) implementation of the decision and (7) reflection and evaluation, are outlined in figure 1.

El objetivo de este artículo es explorar la manera en que Joaquim Xirau y Miguel de Unamuno concibieron el amor. A pesar de que no hay motivos suficientes para concluir una influencia directa y filosóficamente relevante de Unamuno en la obra de Xirau, sí podemos concluir que la forma en que ambos autores concibieron el amor guarda ciertas similitudes. Así, ambos coinciden en concebir la entrega amorosa como un ejercicio de afirmación individual que trae consigo un incremento de la propia (...) singularidad. También, tanto Unamuno como Xirau conciben la entrega amorosa como un acto que, aun surgiendo del propio individuo y no de como es de hecho el mundo, personifica aquello amado, dejando de ser así visto como un mero objeto y mostrándose bajo una forma personal. Y ambos, aunque de un modo distinto, hacen del relato bíblico acerca de la vida y Resurrección de Cristo un aspecto central de sus maneras de entender el amor. (shrink)

The ‘tobacco-free generation’ policy, which bans cigarette sales based on birth year, presents a bold public health initiative but raises significant ethical and practical concerns. As behaviours like drug use become legal and criminal penalties are reduced, singling out smoking for generational restriction appears inconsistent within an increasingly permissive society. Kniess1 critiques this approach for creating inequities by selectively limiting freedoms, conflicting with principles of fairness and adult autonomy. A more balanced public health strategy could involve uniform restrictions on harmful (...) substances or prioritising informed personal choice, supported by harm reduction and education to encourage healthier alternatives. The generational smoking ban targets specific birth cohorts, prohibiting tobacco sales to those born after a certain year. Unlike universal bans, it creates two distinct adult classes—those permitted to smoke and those who are not—resulting in an apparently arbitrary division. Critics, including Schmidt,2 point to the ethical inconsistency of restricting liberties for some while leaving others untouched. This policy design has been defended as a pragmatic compromise, aiming to protect future generations without infringing on the established habits of current smokers (Grill and Voigt).3 Kniess1 evaluates this selective restriction through relational egalitarianism which emphasises the importance of equal social relationships. The cut-off, …. (shrink)

In this paper, I will first of all claim that once one takes proper names as indexicals of a particular sort, indexinames for short, one may account for some tensions that affect our desiderata regarding the use of such names in sentences directly or indirectly involving fiction. According to my proposal, a proper name “N.N.” is an indexical whose character is roughly expressed by the description “the individual called ‘N.N.’ (in context)”, where this description means “the individual one’s interlocutor’s attention (...) is called to by means of ‘N.N.’ (in context)”. This character is a partial function that maps narrow contexts onto referents. Such contexts are enriched narrow contexts, for they also include an ‘acquisition’ parameter, i.e., a parameter filled by a naming practice constituted by a dubbing, which consists in calling via the name one’s interlocutor’s attention to something (if any), and usually also by a certain transmission chain. I will also claim that such a proposal works independently of one’s ontological stance on fictional entities, that is, independently of whether one believes either that there are or that there are no such entities. Moreover, I will claim that such a proposal is better than similar indexicalist proposals such as the one put forward by Tiedke (2011), Finally, I will try to show how this proposal can deal with some objections one may raise against an indexicalist treatment of proper names.

We prove that the maximal order type of the wqo of linear orders of finite Hausdorff rank under embeddability is φ2, the first fixed point of the ε-function. We then show that Fraïssé’s conjecture restricted to linear orders of finite Hausdorff rank is provable in +“φ2 is well-ordered” and, over , implies +“φ2 is well-ordered”.

In philosophy of emerging media, several scholars have insisted on the fact that the “new” of new technologies does not have much to do with communication, but rather with the exponential growth of recording. In this paper, instead, the thesis advanced is that digital technologies do not concern memory, but imagination, and more precisely, what philosophers from Kant onwards have called productive imagination. In this paper, however, the main reference will not be Kant, but Paul Ricoeur, who explicitly refers to (...) the Kantian productive imagination in his works, but also offered an externalized, semioticized, and historicized interpretation of it. The article is developed in three steps. In the first section, it deals with Ricoeur’s theory of narrative, based on the notions of mimesis and mythos. In the second section, it is first argued that human imagination is always-already extended. Second, it will be shown how mimesis and mythos are precisely the way software works. In the third section, the specificity of big data is introduced. Big data is the promise of giving our actions and existences a meaning that we are incapable of perceiving, for lack of sensibility and understanding. Scholars have used the Foucauldian concepts of panopticon and confession for describing the human condition in the digital age. In the conclusion, it is argued that big data makes any form of disclosure unnecessary. Big data is an ensemble of technological artifacts, methods, techniques, practices, institutions, and forms of knowledge aiming at taking over the way someone narratively accounts for himself or herself before the others. Hence, another Foucauldian notion is representative of this age: the parrhesia, to speak candidly, and to take a risk in speaking the truth, insofar as such a possibility is anesthetized. (shrink)

In this paper I will first contend that semantically based arguments in favour of or against problematic entities—like those provided, respectively, in a realist Meinongian and in an antirealist Russellian camp—are ultimately inconclusive. Indeed, only genuinely ontological arguments, specifically addressed to prove (or to reject) the existence of entities of a definite kind, suit the purpose. Thus, I will sketch an argument intended to show that there really are entities of an apparently specific kind, i.e. _intentionalia_, broadly conceived as things (...) that may actually exist as well as actually not exist. Finally, I will try to explain why that argument proves the existence of only some sorts of _intentionalia_, by showing how this is related to the fact that, as some have correctly maintained, _intentionalia_ have no intrinsic nature.

Spartan institutions were pictured as a model of political stability from the Classical period onwards. The so-called Spartan ‘mirage’ did not involve only its constitutional order but also social and economic institutions. Xenophon begins hisConstitution of the Lacedaemoniansby associating Spartan fame with thepoliteiaset up by Lycurgus, which made the Laconian city the most powerful (δυνατωτάτη) and famous (ὀνομαστοτάτη)polisin Greece (Xen.Lac.1.1). In Aristotle'sPolitics, in which the assessment of Sparta is more complex and nuanced, one finds a critique of contemporary Spartan institutions (...) as well as praise for Lycurgus as a great lawgiver who established the laws of Sparta (Arist.Pol.2.1269a69, 2.1273b20). Most other ancient sources often remark upon the unchangeable features of some Spartan institutions as a key aspect of Spartan εὐνομία. Thucydides maintains that, after a long period of war andstasis, the Dorians established excellent laws and Sparta employed the same constitution for more than four hundred years (Thuc. 1.18.1: τετρακόσια καὶ ὀλίγῳ πλείω ἐς τὴν τελευτὴν τοῦδε τοῦ πολέμου ἀφ᾽ οὗ Λακεδαιμόνιοι τῇ αὐτῇ πολιτείᾳ χρῶνται).

Over and above differences in terminology and cultural background, we try to show that the quantum physicist, David Bohm, and poststructuralist philosopher, Gilles Deleuze, shared a common aim in thought: to replace the classical image of reality, which is still dominant in our time, with a metaphysics finally in agreement with the concepts and results of relativity, quantum mechanics andcontemporary biology. For these two thinkers, the world of things that are well individuated in space and time, and ordered according to (...) mechanical relations of cause and effect, are nothing but the momentary expression of an “undivided wholeness in flowing movement” that constitutes its true ontological ground. By means of this new metaphysics, the world of daily experience and classical science appears as the explicit manifestation or development of implicate order that undivided wholeness contains virtually in itself at deeper and deeper levels of envelopment and imbrication. The explicit world is the result of a process of repetition, deceleration and temporal stabilization, triggered by the interaction of our measuring instruments – technical devices, sensory organs and motors, a priori forms and categories of the understanding – with moving wholeness, the thinking and observing subject of which represents a momentary and partial reflection rather than a solitaryand autonomous fragment. By criticizing the classical image of thecorrespondence/adequation of being and thought, Bohm and Deleuzeshow that the thought seeking to grasp this wholeness in flowingmovement inevitably interacts with it – by modifying, recreating andaccomplishing it in one direction rather than another. Thought thusresembles a dance that tries to harmonize with the universal flux thatgenerates and carries it away in a single movement with matter. **************************************************************************************************** ***********************Para além das diferenças de terminologia e de background cultural, tenta-se aqui mostrar que o físico quântico David Bohm e o filósofo pós-estruturalista Gilles Deleuze tiverem um objetivo comum de pensamento: substituir a imagem clássica da realidade, ainda dominante em nossa época, por uma metafísica finalmente de acordo com os conceitos e resultados da relatividade, da mecânica quântica e da biologia contemporânea. Para estes dois pensadores, o mundo das coisas bem individuadas no espaço e no tempo, e ordenadas conforme as relações mecânicas de causa e efeito, não é nada outro que a expressão momentânea de uma “Totalidade indivisa em devir” que constitui seu verdadeiro fundamento ontológico. Pelo meio desta nova metafisica, o mundo da experiência cotidiana e da ciência clássica aparece como a manifestação explicita ou desenvolvida da ordem implícita que a totalidade indivisa contém virtualmente nela mesma em níveis de envolvimento e de imbricação sempre mais profundos. O mundo explícito é o resultado de um processo de repetição, desaceleração e estabilização temporal, desencadeado pela interação de nossos instrumentos de medição -- aparelhos técnicos, órgãos sensoriais e motores, formas “a priori” e categorias do entendimento – com uma totalidade movente no qual o sujeito pensante e observante representa um reflexo momentâneo e parcial ao invés de um fragmento solitário e autônomo. Ao criticar a imagem clássica da correspondência/adequação entre o ser e o pensamento, Bohm e Deleuze mostram finalmente que o pensamento que intenta capturar esta Totalidade em devir interage inevitavelmente com ela, modificando-a, recriando-a e realizando-a em uma direção ao invés de outra. O pensamento se aparenta assim a uma dança que tenta se harmonizar com o flux universal que o gera e o leva em um movimento só com a matéria.Palavras-chave: Bohm; Deleuze; totalidade indivisa em devir; física quântica; pós-estruturalismo; ontologia.

In this paper, I will first try to provide a new argument in favour of the contextualist position on the semantics/pragmatics divide. I will argue that many puns, notably multi-stable ones, cannot be dealt with in the non-contextualist way, i.e., as displaying a phenomenon that effectively involves wide context, the concrete situation of discourse, yet only in a pre-, or at least inter-, semantic sense. For, insofar as they involve ambiguous utterances rather than ambiguous sentences, these puns show that the (...) wide context affecting them has a semantic role: it provides many truth-conditions for a single utterance. Moreover, I will try to show that the contextualist can provide a unitary account of the general phenomenon of puns. On the one hand, this account explains multi-stable puns as well as those puns the non-contextualist claims to deal with successfully, i.e., the ones involving a speaker-induced removal of a well-grounded misunderstanding. On the other hand, it also explains zeugmatic puns, i.e., those involving an ‘impossible’ meaning. (shrink)

Change blindness, the surprising inability of people to detect significant changes between consecutively-presented visual displays, has recently been shown to affect tactile perception as well. Visual change blindness has been observed during saccades and eye blinks, conditions under which people’s awareness of visual information is temporarily suppressed. In the present study, we demonstrate change blindness for suprathreshold tactile stimuli resulting from the execution of a secondary task requiring bodily movement. In Experiment 1, the ability of participants to detect changes between (...) two sequentially-presented vibrotactile patterns delivered on their arms and legs was compared while they performed a secondary task consisting of either the execution of a movement with the right arm toward a visual target or the verbal identification of the target side. The results demonstrated that a motor response gave rise to the largest drop in perceptual sensitivity in detecting changes to the tactile display. In Experiment 2, we replicated these results under conditions in which the participants had to detect tactile changes while turning a steering wheel instead. These findings are discussed in terms of the role played by bodily movements, sensory suppression, and higher order information processing in modulating people’s awareness of tactile information across the body surface.

The paper frames the issue of intergenerational justice by addressing an historical source and a theoretical difficulty. In relation to the historical point of view, the paper offers a preliminary re-reading of the Universal Declaration of Human Rights aimed at revealing the intergenerational commitment that lies behind it (§1). In addressing the second point, it presents the issue of intergenerational justice from a phenomenological perspective (§2). In developing such a perspective, the paper articulates a comprehensive ethical question that is constitutively (...) related to any possible shaping of an intergenerational justice theory (§3). In turn, the explanation of that question presents the opportunity to propose a theory of motivation for the elaboration and implementation of policies explicitly aimed at fulfilling the intergenerational need, beyond any skepticism arising from pragmatic objections. Finally, the paper proposes to address this need by presenting a model of obligation ranking in which the flexibility and strength of the normative bond for the present generation and future ones are considered (§4).
