Scientific disagreements sometimes persist even if scientists fully share results of their research. In this paper we develop an agent-based model to study the impact of diverging diagnostic values scientists may assign to the evidence, given their different background assumptions, on the emergence of polarization in the scientific community. Scientists are represented as Bayesian updaters for whom the diagnosticity of evidence is given by the Bayes factor. Our results suggest that an initial disagreement on the diagnostic value of evidence can, (...) but does not necessarily, lead to polarization, depending on the sample size of the performed studies and the confidence interval within which scientists share their opinions. In particular, the more data scientists share,the more likely it is that the community will end up polarized. (shrink)

The purpose of this paper is to explore the connection between expressivism and disagreement. More in particular, the aim is to defend that one of the desiderata that can be derived from the study of disagreement, the explanation of ‘crossed disagreements’, can only be accommodated within a semantic theory that respects, at the meta-semantic level, certain expressivistic restrictions. We will compare contemporary dynamic expressivism with three different varieties of contextualist strategies to accommodate the specificities of evaluative language –indexical contextualism – (...) truth-conditional pragmatics –, pragmatic strategies using implicatures, and presuppositional accounts. Our conclusion will be that certain assumptions of expressivism are necessary in order to provide a semantic account of evaluative uses of language that can allow us to detect and prevent crossed disagreements.

Theoretical tools aimed at making explicit the injustices suffered by certain socially disadvantaged groups might end up serving purposes which were not foreseen when the tools were first introduced. Nothing is inherently wrong with a shift in the scope of a theoretical tool: the popularization of a concept opens up the possibility of its use for several strategic purposes. The thesis that we defend in this paper is that some public figures cultivate a public persona for whom the conditions of (...) the notion of testimonial injustice might be taken to apply, and this situation is exploited to their advantage, as a means to advance their political agendas. More specifically, they take advantage of this to generate situations of crossed disagreements, which in turn foster polarization. (shrink)

Las herramientas teóricas destinadas a señalar las injusticias que sufren ciertos grupos socialmente oprimidos pueden acabar siendo utilizadas con propósitos completamente opuestos a los iniciales. Modificar el alcance de una herramienta teórica no es necesariamente problemático: la popularización de un concepto abre las puertas a que se utilice estratégicamente para diferentes fines. La tesis que defendemos en este artículo es que algunos personajes públicos cultivan una imagen particular de sí mismos que parece satisfacer los requisitos de la noción de injusticia (...) testimonial y utilizan esta situación como medio para obtener beneficio político de ella. Más concretamente, estos personajes públicos se benefician de esta condición para generar situaciones de desacuerdos cruzados, que están estrechamente relacionados con el aumento de la polarización.

Contemporary biological research has suggested that some host–microbiome multispecies systems (referred to as “holobionts”) can in certain circumstances evolve as unique biological individual, thus being a unit of selection in evolution. If this is so, then it is arguably the case that some biological adaptations have evolved at the level of the multispecies system, what we call hologenomic adaptations. However, no research has yet been devoted to investigating their nature, or how these adaptations can be distinguished from adaptations at the (...) species-level (genomic adaptations). In this paper, we cover this gap by investigating the nature of hologenomic adaptations. By drawing on the case of the evolution of sanguivory diet in vampire bats, we argue that a trait constitutes a hologenomic adaptation when its evolution can only be explained if the holobiont is considered the biological individual that manifests this adaptation, while the bacterial taxa that bear the trait are only opportunistic beneficiaries of it. We then use the philosophical notions of emergence and inter-identity to explain the nature of this form of individuality and argue why it is special of holobionts. Overall, our paper illustrates how the use of philosophical concepts can illuminate scientific discussions, in the trend of what has recently been called metaphysics of biology. (shrink)

Bourrat and Griffiths :33, 2018) have recently argued that most of the evidence presented by holobiont defenders to support the thesis that holobionts are evolutionary individuals is not to the point and is not even adequate to discriminate multispecies evolutionary individuals from other multispecies assemblages that would not be considered evolutionary individuals by most holobiont defenders. They further argue that an adequate criterion to distinguish the two categories is fitness alignment, presenting the notion of fitness boundedness as a criterion that (...) allows divorcing true multispecies evolutionary individuals from other multispecies assemblages and provides an adequate criterion to single out genuine evolutionary multispecies assemblages. A consequence of their criterion is that holobionts, as conventionally defined by hologenome defenders, are not evolutionary individuals except in very rare cases, and for very specific host-symbiont associations. This paper is a critical response to Bourrat and Griffiths’ arguments and a defence of the arguments presented by holobiont defenders. Drawing upon the case of the hologenomic basis of the evolution of sanguivory in vampire bats, I argue that Bourrat and Griffiths overlook some aspects of the biological nature of the microbiome that justifies the thesis that holobionts are evolutionarily different to other multispecies assemblages. I argue that the hologenome theory of evolution should not define the hologenome as a collection of genomes, but as the sum of the host genome plus some traits of the microbiome which together constitute an evolutionary individual, a conception I refer to as the stability of traits conception of the hologenome. Based on that conception I argue that the evidence presented by holobiont defenders is to the point, and supports the thesis that holobionts are evolutionary individuals. In this sense, the paper offers an account of the holobiont that aims to foster a dialogue between hologenome advocates and hologenome critics. (shrink)

Editors' preface to the book symposium on Michael Ayers' Knowing and Seeing. Groundwork for a New Empiricism (OUP 2019).

The hologenome concept of evolution is a hypothesis about the evolution of animals and plants. It asserts that the evolution of animals and plants was partially triggered by their interactions with their symbiotic microbiomes. In that vein, the hologenome concept posits that the holobiont (animal host + symbionts of the microbiome) is a unit of selection. -/- The hologenome concept has been severely criticized on the basis that selection on holobionts would only be possible if there were a tight transgenerational (...) host-genotype-to-symbiont-genotype connection. As our current evidence suggests that this is not the case for most of the symbiont species that compose the microbiome of animals and plants, the opportunity for holobiont selection is very low in relation to the opportunity for selection on each of the species that compose the host microbiome. Therefore, holobiont selection will always be disrupted ‘from below’, by selection on each of the species that compose the microbiome. -/- This thesis constitutes a conceptual effort to defend philosophically the hologenome concept. I argue that the criticism according to which holobiont selection requires tight transgenerational host-genotype-to-symbiont-genotype connection is grounded on a metaphysical view of the world according to which the biological hierarchy needs to be nested, such that each new level of selection includes every entity from below. Applied to hologenomes, it entails that the hologenome is a collection of genomes, and selection of hologenomes is assumed to entail cospeciation of the host with the species that constitute its microbiome. -/- Against that interpretation, I propose the ‘stability of traits’ account, according to which hologenome evolution is the result of the action of natural selection in a non-nested hierarchical world. In that vein, hologenome evolution does not entail cospeciation, and thus it does not require tight transgenerational host-genotype-to-symbiont-genotype connection. By embracing a multilevel selection perspective, I argue that hologenome evolution results from the simultaneous action of natural selection on each of the lineages that compose the microbiome, and on the assemblage composed by the host genome plus the functional traits of its microbiome. Hologenome selection occurs when the evolution of the traits of the microbiome result from their effects on the fitness of the host, and it can take the form of multilevel selection 1, or multilevel selection 2. In both cases, hologenome selection entails the evolution of microbiome traits, as well as evolution of the host genome, rather than cospeciation of lineages. (shrink)

Taking a cue from the interpretive difficulties faced by Socrates and his interlocutors in Plato’s Theaetetus as they struggle to determine the meaning of Protagoras’ homo-mensura doctrine (HM), I argue that Protagoras, or early Protagoreans, used HM to speak on the relativity of literary criticism. For evidence I adduce an overlooked passage of the anonymous Certamen Homeri et Hesiodi, which contains an ethical formulation of HM. This formulation of HM, compatible with the portrait of Protagoras from Theaetetus, explains the concern (...) for literary interpretation latent in two sections of the Certamen. From the evidence in the Certamen, we may infer that HM was directly related to Protagorean education in civic virtue, part of which included a study of how to read and listen to texts. (shrink)

En el presente escrito se hace una lectura filosófica de la ética protestante a partir de un talante predominante en la época que circunscribe al barroco mostrándoles como una forma fundamental y fundacional de la Modernidad europea ejemplificado a través del drama trágico alemán y en contraste con una configuración alternativa y desemejante de un proyecto civilizatorio propiamente barroco y utópico en las colonias americanas. Palabras clave: Barroco - Talante - Protestantismo - Modernidad - Ethos.

La ciencia de la política en el siglo veinte ha llegado a una difícil situación. La vida ha sufrido convulsiones inesperadas mientras que la ciencia que debía entender lo sucedido ha quedado apresada por la perplejidad y pos sus fracasos en la predicción y explicación de los acontecimientos. En tono crítico, el autor mantiene que "una ciudadanía de hombres y mujeres vigilantes es un dogma nuevo que no debe pasar desapercibido". La emancipación colonial, el holocausto, la caída del muro de (...) Berlín y las transformaciones vertiginosas de la tecnología han arrastrado a la ciencia política y a sus investigadores a una situación comprometida. En este libro, el autor reconstruye la teoría política del siglo veinte a través de sus grandes maestros y reclama un saber que no se separe de los hombres y mujeres que dan vida a la política cotidiana y real.

While punishment is a longstanding object of philosophical scrutiny, other controversial aspects of the justice system, such as policing, have flown under the radar. In this paper, we consider possible reasons why philosophers interested in crime and punishment have neglected policing. We make the case for a broader account of the political morality of the justice system, with a particular emphasis on policing. We sketch the outlines of an egalitarian version of such a theory, highlighting parallels between policing and the (...) welfare state. Finally, we turn to recent calls for police abolition. Evaluating such radical claims requires, we argue, going beyond the traditional confines of the philosophy of punishment and considering a more holistic and interdisciplinary theory of criminal justice.

The units or levels of selection debate concerns the question of what kind of biological systems are stable enough that part of their evolution is a result of the process of natural selection acting at their level. Traditionally, the debate has concerned at least two different, though related, questions: the question of the level at which interaction with the environment occurs, and the question of the level at which reproduction occurs. In recent years, biologists and philosophers have discussed a new (...) aspect of this debate, namely the possibility that certain multi-species consortia formed by a host and its microbiome may act as a unit of selection. This thesis, however, has not been without criticism, as it is doubtful that such consortia could meet the conditions required to achieve the degree of stability that would allow them to experience natural selection. The purpose of this paper is to systematically examine such criticisms and to defend the thesis that the holobiont/hologenome can act as a genuine level of selection both in the form of an interactor and in the form of a reproducer. To do so, it will be argued that the microbiome should be characterized in functional rather than taxonomic terms. (shrink)

We present a Hilbert-style axiomatization of a recently introduced logic, called G'3 G'3 is based on a 3-valued semantics. We prove a soundness and completeness theorem. The replacement theorem holds in G'3. As it has already been shown in previous work, G'3 can express some non-monotonic semantics. We prove that G'3can define the same class of functions as Lukasiewicz 3 valued logic. Moreover, we identify some normal forms for this logic.

We introduce the large-cardinal notions of ξ-greatly-Mahlo and ξ-reflection cardinals and prove (1) in the constructible universe, L, the first ξ-reflection cardinal, for ξ a successor ordinal, is strictly between the first ξ-greatly-Mahlo and the first Π1ξ-indescribable cardinals, (2) assuming the existence of a ξ-reflection cardinal κ in L, ξ a successor ordinal, there exists a forcing notion in L that preserves cardinals and forces that κ is (ξ+1)-stationary, which implies that the consistency strength of the existence of a (ξ+1)-stationary (...) cardinal is strictly below a Π1ξ-indescribable cardinal. These results generalize to all successor ordinals ξ the original same result of Mekler–Shelah [A. Mekler and S. Shelah, The consistency strength of every stationary set reflects, Israel J. Math.67(3) (1989) 353–365] about a 2-stationary cardinal, i.e. a cardinal that reflects all its stationary sets. (shrink)

El presente artículo es producto de una investigación multidisciplinaria e interinstitucional, fruto de la alianza entre la Universidad de San Buenaventura Medellín y el Centro de Familia VID-Obra de la Congregación Mariana de Medellín. Surge de una inquietud respecto a la manera en que se aborda la realidad institucional de las madres cabeza de familia, tanto en el ámbito político como empresarial. Para estudiar esta realidad, se partió de un modelo de investigación cualitativo, en donde se hizo una aproximación a (...) la población a partir de un cuestionario que permitiera identificar los roles y percepciones frente al ejercicio de la maternidad y la jefatura femenina, específicamente, cuando se trata de madres trabajadoras. Los resultados arrojados por la investigación permiten obtener una mirada psicosocial de la forma en que se ejerce el rol de madre y de figura de articulación familiar. (shrink)
