C.S. Peirce defended a pragmatist view of assertion in terms of its normative effect. This paper has two goals. First, to reconstruct and assess Peirce’s argument for the thesis that to assert a proposition is to make oneself responsible for its truth. Second, to argue that Peirce interpreted “responsibility for truth” as the acquisition of a dialogical commitment, namely, the duty to defend the proposition asserted by giving reasons upon challenge.

The present work consists of a discussion about the concept of real number in Frege. It is intended to explain how Frege tries to define the real numbers, highlighting the importance that the notion of “magnitude-ratio” plays in this definition. In Part III, in Volume II of the Grundgesetze der Arithmetik (1903) (from now on only: Grundgesetze), Frege presents his theory of real numbers, which is followed by a long criticism of the real number theories in force at that time, (...) such as by Cantor, Dedekind, Thomae and Weierstrass. In view of this, to fulfill our purpose, we will examine the text only where Frege presents his own theory of real numbers (the informal presentation) (§§156-164). Frege's criticisms of previous theories will not be examined in detail, unless an introduction to his criticism of formalism, in order to elucidate such criticism. Thus, only the part in which the philosopher presents his own conception of real numbers will be analyzed. To support the discussion, authors Peter Simons, Eric Snyder and Stewart Shapiro will be used. (shrink)

One usually makes assertions by means of uttering indicative sentences like “It is raining”. However, not every utterance of an indicative sentence is an assertion. For example, in uttering “I will be back tomorrow”, one might be making a promise. What is to make an assertion? C.S. Peirce held the view that “to assert a proposition is to make oneself responsible for its truth” (CP 5.543). In this thesis, I interpret Peirce’s view of assertion and I evaluate Peirce’s reasons for (...) holding it. I begin by reconstructing and assessing Peirce’s case for such view as it appears in (EP 2.140, 1903), (EP 2.312-313, 1904), and (CP 5.546, 1908). Then, I continue by elaborating on three aspects of Peirce’s view of assertion, namely, assertion as an act involving a certain kind of responsibility, the proposition as what is asserted, and responsibility for truth as a responsibility to give reasons. With respect to these three aspects, I argue for the following claims: (1) Peirce construed the responsibility involved in asserting as a moral responsibility; (2) Peirce held that propositions are types; and (3) Peirce was committed to a dialogical interpretation of “responsibility to give reasons”. Finally, I end by presenting two objections to Peirce’s view of assertion and its corresponding replies. I conclude that Peirce’s account of assertion is a valuable contribution to the philosophical debate on assertion. (shrink)

In this paper we present a new framework of idealization in biology. We characterize idealizations as a network of counterfactual and hypothetical conditionals that can exhibit different “degrees of contingency”. We use this idea to say that, in departing more or less from the actual world, idealizations can serve numerous epistemic, methodological or heuristic purposes within scientific research. We defend that, in part, this structure explains why idealizations, despite being deformations of reality, are so successful in scientific practice. For illustrative (...) purposes, we provide an example from population genetics, the Wright-Fisher Model. (shrink)

BackgroundViral pandemics present a range of ethical challenges for policy makers, not the least among which are difficult decisions about how to allocate scarce healthcare resources. One important question is whether healthcare workers should receive priority access to a vaccine in the event that an effective vaccine becomes available. This question is especially relevant in the coronavirus pandemic with governments and health authorities currently facing questions of distribution of COVID-19 vaccines.Main textIn this article, we critically evaluate the most common ethical (...) arguments for granting healthcare workers priority access to a vaccine. We review the existing literature on this topic, and analyse both deontological and utilitarian arguments in favour of HCW prioritisation. For illustrative purposes, we focus in particular on the distribution of a COVID-19 vaccine. We also explore some practical complexities attendant on arguments in favour of HCW prioritisation.ConclusionsWe argue that there are deontological and utilitarian cases for prioritising HCWs. Indeed, the widely held view that we should prioritise HCWs represents an example of ethical convergence. Complexities arise, however, when considering who should be included in the category of HCW, and who else should receive priority in addition to HCWs. (shrink)

El presente artículo tiene como principal objetivo introducir al lector algunos de los conceptos fundamentales de la filosofía de Gottlob Frege. Estos son: el binomio sentido/referencia, el valor veritativo de oraciones con elementos no referenciales, la distinción entre pensar, juzgar y aseverar, su concepción de los indéxicos y los demostrativos, así como su defensa de la existencia de un tercer reino. En algunos de ellos se mostrarán algunas problemáticas asociadas que han sido destacados por pensadores de renombre. Tal es el (...) caso, por ejemplo, de la famosa crítica de Bertrand Russell a la semántica de Frege por su incapacidad para dar cuenta del valor de verdad de oraciones ficticias. Dirigido especialmente al lector lego en la materia, aunque sin perder rigor académico, este trabajo procura presentar algunas de las principales tesis fregeanas a través de sus fuentes primarias.

This thesis is a sceptical investigation into the notion that the metaphorical wave-particle binary of Virginia Woolf's To the Lighthouse is related to quantum physics. Indeed, the field of literature and science has employed conceptual similarities as the main means of connecting quantum concepts to novels, however, this has led to a host of scholarly difficulties, prompting the need for a re-examination of analogical linkages. Woolf is the model candidate for such a re-examination, given her historical and philosophical proximity with (...) the developments of quantum mechanics. To the Lighthouse, in particular, was written between 1925 and 1927: precisely when quantum physicists were attempting to resolve the wave-particle duality, leading to Niels Bohr's complementarity. This parallel has been noted by researchers as relevant to the novel, as it too displays a general binary that can be read as wave-particle-like, which the author also attempts to resolve along similar philosophical lines. Nevertheless, other than proximity and similarity, there are no reasons to affirm that the science is related to the novel; hence, it is an ideal case study to examine in order to ascertain the value of conceptual similarities in literature and science. To do so, To the Lighthouse's binary and its resolution are interpreted in a thesis-long close reading, in order to compare aspects of it firstly to Woolf's personal thought, and secondly to various non-quantum intellectual contexts that preceded and surrounded her. In doing so, it becomes clear not only that invoking quantum physics serves no clear purpose in better understanding the novel, but also that the notion of resolving wave- particle-like binaries was a widespread philosophical procedure at the turn of the century, decades before Bohr's concept. This negative conclusion interrogates what the scholarly value of interpreting similarities is, though a hypothetical solution can be found in conceptual metaphor theory. (shrink)

There are several reasons to believe that there is a predominance of suffering over wellbeing in nature. The difference grows exponentially when the suffering of invertebrates is taken into consideration. Given the relevance of the experience of pain when it comes to attributing moral considerability to an individual, the seriousness and implications of the above statements are significant due to the need to reconcile the interests of an enormous number of individuals who experience pain to some degree. Depending on the (...) species and the ecosystem, there are variations that must be kept in mind with the aim of reducing the existing amount of suffering. (shrink)

Far from being rigorously defined, the concept of species in a biologicalsense has suffered from imprecision since Charles Darwin. This is mainlydue to the absence of a definition that allows to combine within eachspecies the organisms that are considered part of it. The objective of thiswork is to show, on the one hand, the diversity of characterizations of theconcept of species as well as their respective problems and, on the other,the different sustainable ontological positions. As a consequence of theaforementioned imprecision, (...) the ethical consequences that this entails inthe debate about speciesism are analyzed. (shrink)

Invertebrate animals are usually seen as a kind of “aliens” which do not deserve any moral consideration. However, there is a growing amount of evidenceindicating that many of them do have the capacity to experience pain. The samecriteria that are usually applied in order to infer that vertebrates are sentient beings (behavioral response, learning capacity, memory, a certain specific neurophysiological structure…) lead to the idea that many invertebrates aresentient as well. Therefore, under the skeptical premise that we have no directevidence (...) of the experience of pain in vertebrates, we are forced to hold that itexists in both vertebrates and invertebrates.

In this paper, I show that Polleit and Mariano (2011) are right in concluding that Credit Default Swaps (CDS) are per se unobjectionable from Rothbard’s libertarian perspective on property rights and contract theory, but that they fail to derive this conclusion properly. I therefore outline the proper explanation. In addition, though Polleit and Mariano are correct in pointing out that speculation with CDS can conceivably hurt the borrowers’ interests, they fail to grasp that this can be the case only in (...) some peculiar circumstances that I identify. In other words, they miss the bigger picture, the one outside special circumstances, in which CDS trading has the opposite effect. That is, CDS facilitate debt accumulation, including government debt accumulation. Finally, I point out how this can precipitate the collapse of fiat money regimes. An incidental goal of the analysis is to provide a better account than Polleit and Mariano of recent government interventions in and around CDS markets. (shrink)

Así habló Zaratustra continúa siendo, 135 años después de su publicación, la principal obra del corpus filosófico nietzscheano. Más de un siglo después de su surgimiento, este trabajo permanece como una fuente inagotable de relecturas cuyo sentido, en aras de evitar interpretaciones negligentes, conviene explicitar cada cierto tiempo. Por este motivo, el presente trabajo se erige como un análisis renovado de Así habló Zaratustra, centrado en la clarificación conceptual de las que se consideran son sus cinco principales ideas desde el (...) propio texto. A saber: la “muerte de Dios”, el Übermensch, la “voluntad de poder”, el “eterno retorno de lo mismo” y la “asunción/superación del nihilismo”. Para ello, previamente partiremos de una breve aproximación al contexto filosófico del autor, al contexto de la propia obra en el conjunto de la producción nietzscheana, así como a una indispensable presentación del estilo narrativo de esta.

This article examines the British colonial theft of Indigenous sovereignty and the particular obstacles that it presents to establishing just social relations between the colonizer and the colonized in settler states. In the first half, I argue that the particular nature of the crime of sovereign theft makes apologies and reparations unsuitable policy tools for reconciliation because Settler societies owe their very existence to the abrogation of Indigenous sovereignties. Instead, Settler states ought to return sovereignty to the land’s Indigenous peoples. (...) In the second half of this paper, I take up some of the practical questions of how this might be done and anticipate a number of objections. Giving up sovereignty would not mean dispossessing the millions of colonists who currently reside in these countries of their homes and property – but it does mean rethinking the constitutional makeup of a country and how that serves to benefit the different peoples who make their homes there.

Defences of Williamson’s Anti-Luminosity Argument (ALA) that employ doxastic propagation principles—i.e., rules by which cases of beliefs and/or dispositions to believe are inferred from other such cases—risk running into sorites. Since these principles are explainable by an ineffective capacity to phenomenally discriminate between two adjacent cases, luminist rejections of the ALA can halt sorites by denying doxastic propagation, thereby reaffirming these discriminative capacities as appropriately effective. One potent method of resisting the luminist involves recharacterizing discriminative capacities in terms of a (...) distinction between beliefs and their underlying dispositions to reinstate the plausibility of doxastic propagation. To this effect, I propose a novel coarse-grained approach favouring the ALA that leverages a modal analysis of the belief/ disposition distinction. This motivates a sharp threshold between belief and absent belief that neither succumbs to sorites nor begs the question against the luminist. The upshot of this approach is substantial: by conferring a dialectical advantage to the anti-luminist, the luminist is held to highly problematic positions, regarding the trivialisation of safety and the relationship between beliefs and dispositions, if they deny the coarse-grained approach at many of its components.

For many, putting in doubt the existence of phenomenal consciousness is absurd since the distinction between appearance and reality does not apply to it. Many cognitive scientists and neuroscientists accept the existence of consciousness in virtue of such reasoning. The present work questions that justification. Consciousness is a concept whose scientific meaning comes from philosophy or colloquial language. From this, it concludes that the “self-evident nature of consciousness” is not a scientifically valid statement. This philosophical assumption rests on a category (...) mistake in scientific language use. (shrink)

The Pastoral Constitution, Gaudium et Spes, is a key document for fundamental theology. In it, for the first time, the Church openly discusses the anthropological question as a specific theme. It explains what Christian anthropology is and in what way the mystery of Christ sheds light on the mystery of man. From the point of view of fundamental theology, the document shows how theological reason is closely related to anthropological meaning. It takes note of the potential mediatory role of anthropology (...) in a dialogue between faith and reason in the modern world. (shrink)

The radical mean suggested by Socrates in order to carry out the program of the Republic - the relegation to the fields of all inhabitants over the age of 10 - has perplexed modern commentators who have seen in it an ironical remark, a reductio ad absurdum presented in order to establish the very impossibility of Kallipolis or, on the contrary, a sign of the totalitarian and criminal character of the Platonic city. But it is far from evident, in view (...) of political or military events prior and contemporary with the redaction of the Republic, that this solution could offend the moral conscience of fourth-century Greeks. This practice even seems to be the logical consequence of a certain oligarchic or aristocratic ideology, common by the end of the 5th c. and at the beginning of the 4th c., which associated, on the one hand, rural organization with the ‘best regime’ and, on the other, urban centralisation with democracy. The actual practices of the Lacedaemonian city, which maintained its primitive organization in komai, and even tried to impose it to other cities, could also serve as a model for the opponents of Athenian democracy. All of Plato's political models, from the Republic to the Laws, present cities whose essential, if not exclusive, productive activity is agriculture. The displacement of the population to the countryside seems, from this perspective, a rather serious proposal of the philosopher. * * Agradezco a Héctor Zagal y a María-Elena García-Peláez por sus observaciones y sugerencias al texto en español.

In most jurisdictions where euthanasia is legal, patients seeking euthanasia need to seek out the approval of their request from two clinicians (one of who is a psychiatrist). These doctors are required to assess whether euthanasia is ‘appropriate’ for the patient in question. In this paper I claim that doctors qua doctors are not qualified (or, at least, not typically) to evaluate suffering of an existential kind, and consequently they are not qualified to 'evaluate' the requests of patients seeking euthanasia. (...) Importantly, this argument is only focused on patients who are seeking euthanasia on account of acute suffering. To defend my central thesis, I discuss the limits of the professional expertise of clinicians, in addition to considering the nature of suffering experienced by patients requesting euthanasia (which is, typically, a combination of physiological, psychological and existential suffering).

In this essay, I look at the significant portion of vegans who are vegan because they care about harm to animals. I investigate what lifestyle is in fact consistent with caring about harm to animals, which I begin by calling consistent veganism. I argue that the lifestyle that consistently follows from this underlying conviction behind many people’s veganism is in fact distinct from a vegan lifestyle.

L’article introduit au rôle de l’efficience dans la génération d’avantages ou de désavantages enregistrés par les minorités. L’objectif est de démontrer que l’efficience devrait jouer un rôle plus important dans le domaine de la justice ethnoculturelle. Pour ce faire, une brève présentation de la place du nombre dans la littérature sur le sujet est offerte, ce qui permet de saisir le fond de l’argument consistant à faire des déséquilibres numériques une source certaine des injustices subies par les minorités, notamment dans (...) une perspective inspirée par l’égalitarisme de la chance. De ce point de vue, l’asymétrie numérique peut toutefois constituer une source d’avantages pour ces groupes. Dès lors, une telle asymétrie, qui est l’un des constituants de la définition de la minorité, prend une autre dimension. Plus que cette asymétrie, il apparaît que c’est l’efficience (la manière dont les groupes gèrent cette asymétrie) qui détermine les conditions et succès matériels des membres d’un groupe donné. Après une discussion des minorités efficientes et dominantes, l’article se conclut par la mise en lumière de quelques pistes de recherche rendues visibles par l’efficience et qui sont pertinentes pour la théorie de la justice en contexte multiculturel.

Cet article évalue, du point de vue moral, les justifications possibles pour le recours à la taxation en vue de promouvoir des comportements « sains ». L’objectif est de démontrer qu’un tel instrument recevrait une meilleure justification, c’est-à-dire plus en accord avec des principes égalitariens respectueux de la liberté individuelle, s’ils s’inscrivaient dans une logique de mutualisation. Pour ce faire, les arguments du bien-être individuel et de l’efficience sociale sont discutés afin d’en pointer les fécondités et limites. Au travers de (...) leurs limites, ces arguments introduisent naturellement à une troisième manière d’appréhender le problème, sous l’angle de la mutualisation. Ce principe représente moins une remise en cause radicale des arguments précédents qu’une reformulation du recours à l’efficience sociale et une limitation du champ d’application des appels au bien-être individuel. Il repose sur deux idées. La première est que la référence à une notion de responsabilité, même affadie, est nécessaire. De plus, celle-ci doit être conçue comme partagée entre producteurs et consommateurs ainsi que limitée au domaine financier. La seconde est que la mutualisation ne peut être déconnectée d’intuitions égalitariennes formulées de manière générale. (shrink)

Why is space 3-dimensional? The fi rst answer to this question, entirely based on Physics, was given by Ehrenfest, in 1917, who showed that the stability requirement for n-dimensional two-body planetary system very strongly constrains space dimensionality, favouring 3-d. This kind of approach will be generically called "stability postulate" throughout this paper and was shown by Tangherlini, in 1963, to be still valid in the framework of general relativity as well as for quantum mechanical hydrogen atom, giving the same constraint (...) for space{dimensionality. In the present work, before criticizing this methodology, a brief discussion has been introduced, aimed at stressing and clarifying some general physical aspects of the problem of how to determine the number of space dimensions. Then, the epistemological consequences of Ehrenfest's methodology are critically reviewed. An alternative procedure to get at the proper number of dimensions, in which the stability postulate - and the implicit singularities in three-dimensional physics - are not an essential part of the argument, is proposed. In this way, the main epistemological problems contained in Ehrenfest's original idea are avoided. The alternative methodology proposed in this paper is realized by obtaining and discussing the n-dimensional quantum theory as expressed in Planck's law, de Broglie relation and the Heisenberg uncertainty relation. As a consequence, it is possible to propose an experiment, based on thermal neutron di raction by crystals, to directly measure space dimensionality. Finally the distinguished role of Maxwell's electromagnetic theory in the determination of space dimensionality is stressed. (shrink)

Culture as a dynamic system of meaningful relations can naturally accommodate a hermeneutic analysis. In this essay, the notion of Gadamer’s hermeneutics as involving interpretable meaning throughout experiential reality permits a natural concordance with an understanding of culture as meaningful. The Gadamerian idea that prejudices inform the horizons that make our experiences intelligible is applied to the view that culture is both a self-enclosed structure that is given by one’s horizon and one that continuously points past this horizon in genuine (...) dialogue. Nevertheless, in seeing culture as a coherent system that transcends itself, we are consequently faced with a dilemma regarding the evolution of one’s cultural horizons: whether past horizons can survive the creation of novel ones through dialogue. However, this may be resolved through Gadamer’s understanding of the functions of sameness and difference within horizonal evolution, and how these functions feature in the distinction between a shared ontological ground and the horizons through which the ground is interpreted. Ultimately, we showcase how it is noncontradictory to suppose that culture is both self- and other-referential. (shrink)

In this article it is shown that a careful analysis of Kant 's Gedanken von der wahren Schätzung der lebendigen Kräfte und Beurtheilung der Beweise leads to a conclusion that does not match the usually accepted interpretation of Kant 's reasoning in 1747, according to which the young Kant supposedly establishes a relationship between the tridimensionality of space and Newton's law of gravitation. Indeed, it is argued that this text does not yield a satisfactory explanation of space dimensionality, and actually (...) restricts itself to justifying the tridimensionality of extension. (shrink)

Metascientific criteria used for explaining or constraining physical space dimensionality and their historical relationship to prevailing causal systems are discussed. The important contributions by Aristotle, Kant and Ehrenfest to the dimensionality of space problem are considered and shown to be grounded on different causal explanations: causa materialis for Aristotle, causa efficiens for young Kant and an ingenious combination of causa efficiens and causa formalis for Ehrenfest. The prominent and growing rôle played by causa formalis in modern physical approaches to this (...) problem is emphasized. (shrink)

Kantian Deontological Ethics concerns itself with the will as grounded in universalisable maxims. Such maxims are in turn based on rationally conceived laws that, in a professional setting, find expression in the autonomously made agreements constituting professional protocols and regulations. When applied to a case-study wherein public safety has been possibly jeopardised by company products, we can argue for priority in the agreed-to responsibility towards the good of professional autonomy, expressed as a rational mandate of nondisclosure of confidential product information, (...) over that of the good of public safety. This priority persists regardless of whether the good of truth, such as the disclosure of confidential product information, has its value grounded in itself or the good of safety. Nevertheless, company and individual professional responsibility may prioritise safety over autonomy, but how this prioritisation is made must be sensitive to the autonomously willed choice of the employed professional.

Arguments concerning the nature of natural evil vary in their conclusions depending on the particular approach with which they commence inquiry; one of the most contested conclusions regards evil as privation, sourcing its justification primarily from Aquinas’ metaphysical conception of good as being and evil as non-being. It should be of no surprise, then, that the dismissal of natural evil’s privative nature comes about when the understanding of natural evil favours a phenomenological approach rather than a metaphysical one. Proponents of (...) said dismissal generally centre their claims around the notion of pain and suffering as substantially contentful – as in, non-privative – experiences of evil. On the other hand, theorists espousing the privation account generally argue that characterisations of pain and suffering as necessarily evil do not consider the context of orientation towards individual wellbeing within which pain/suffering experiences naturally function. Furthermore, some of the arguments for the privation account’s dismissal seem to disregard completely the Thomistic sense of the form and hierarchy of the good, which ends up straw-manning the privation account to a point where it can no longer reconcile the awfulness of experienced pain and suffering with these experiences not being necessarily evil. The importance of understanding this Thomistic sense is further emphasised in its capacity to explain why a divine and fully good Creator would involve the world with such evil. Thus, this paper first considers the account of evil given in question one of Aquinas’ De malo, along with contemporary arguments for the nature and purpose of evil as privation; second, these are then used as resources to help make sense of, one, the general nature of pain and suffering, and two, some of their specific expressions as found in disease and depression, and throughout evolutionary history.

This paper introduces the Las Piñas Bamboo Organ as a cultural treasure. By interviewing four key individuals related to the bamboo organ, the paper discusses the history, present condition, and activities related to the preservation and sustenance of the bamboo organ. Interview, a method of oral history, was chosen to let the people involved share their own memories and experiences that are not usually featured in written documents about the bamboo organ. The following themes emerged from the interviews: (1) the (...) introduction of Father Diego Cera as an organ builder, (2) the motivations in using bamboo as the main material of the bamboo organ, (3) the quality of the sound produced by the bamboo organ, (4) the restoration of the bamboo organ, (5) the beginnings, objectives, and activities of the Bamboo Organ Foundation, Inc., (6) the beginnings and objectives of the International Bamboo Organ Festival and the activities related to it, (7) the problems that the bamboo organ faces, and (8) the importance of training organists. The researchers also identified the implications of the conservation of the bamboo organ in the economic, social, ecological, and cultural aspects of the city’s social life based on its potentials for development. This paper can be a useful primary source for future researchers of the bamboo organ and the local history of Las Piñas. (shrink)

According to Kuhn’s account of the nature of scientific paradigms, how one experiences the world varies drastically from one context to another depending on the accepted paradigm of the context in question. In other words, one’s pre-existing conceptual structure concerning the world not only acts as an epistemological framework for its possible understanding, but also fundamentally affects the phenomenological observations of the world as something; this latter function of the conceptual structure motivates the view that mature scientific paradigms/theories and the (...) data of scientific observation/experimentation are essentially two sides of the same coin. What is interesting, then, is that even between different historical eras that generally regarded the world in clearly incompatible ways, albeit still informed by paradigms, Kuhn still attributes scientific knowledge to each. To make sense of this, the explanatory resources of epistemological contextualism are used to specify potentially one way in which epistemic standards for knowledge must change between different historical eras for one to justifiably claim scientific knowledge within these different contexts. As we shall see, the argument for Kuhn’s account of paradigm being contextualist in character is apparently best made through the notion of doubt-driven context-shifts as actualising change in the form of P between different contexts in which “S knows that P” is asserted. As such, this paper first explores Kuhn’s account of scientific knowledge and paradigms before considering how the account can be considered contextualist in nature. Moreover, other context-concerned systems, such as Traditional, and Subject-Sensitive Invariantism, are briefly investigated to substantiate claims of what cannot be accurately ascribed to Kuhn’s epistemology.
