We introduce a family of rules for adjusting one's credences in response to learning the credences of others. These rules have a number of desirable features. 1. They yield the posterior credences that would result from updating by standard Bayesian conditionalization on one's peers' reported credences if one's likelihood function takes a particular simple form. 2. In the simplest form, they are symmetric among the agents in the group. 3. They map neatly onto the familiar Condorcet voting results. 4. They (...) preserve shared agreement about independence in a wide range of cases. 5. They commute with conditionalization and with multiple peer updates. Importantly, these rules have a surprising property that we call synergy - peer testimony of credences can provide mutually supporting evidence raising an individual's credence higher than any peer's initial prior report. At first, this may seem to be a strike against them. We argue, however, that synergy is actually a desirable feature and the failure of other updating rules to yield synergy is a strike against them.

A number of recent papers have criticized what they call the dynamical interpretation of evolutionary theory found in Elliott Sober’s The Nature of Selection. Sober argues that we can think of evolutionary theory as a theory of forces analogous to Newtonian mechanics. These critics argue that there are several important disanalogies between evolutionary and Newtonian forces: Unlike evolutionary forces, Newtonian forces can be considered in isolation, they have source laws, they compose causally in a straightforward way, and they are intermediate (...) causes in causal chains. Here we defend and extend the forces analogy by arguing that each of these criticisms is based on a misunderstanding of Newtonian forces. Our discussion also has the interesting consequence that natural selection turns out to be more similar to forces such as friction and elastic forces rather than the more canonical gravitation.

We argue for a new conventionalism about many kinds of evolutionary groups, including clades, cohesive units, and populations. This rejects a consensus, which says that given any one of the many legitimate grouping concepts, only objective biological facts determine whether a collection is such a group. Surprisingly, being any one kind of evolutionary group typically depends on which of many incompatible values are taken by suppressed variables. This is a novel pluralism underlying most any one group concept, rather than a (...) familiar pluralism claiming many concepts are legitimate. Consequently, we must help biological facts determine grouphood, even when given a single grouping concept. (shrink)

Phylogenetic trees are meant to represent the genealogical history of life and apparently derive their justification from the existence of the tree of life and the fact that evolutionary processes are treelike. However, there are a number of problems for these assumptions. Here it is argued that once we understand the important role that phylogenetic trees play as models that contain idealizations, we can accept these criticisms and deny the reality of the tree while justifying the continued use of trees (...) in phylogenetic theory and preserving nearly all of what defenders of trees have called the “importance of tree thinking.”. (shrink)

Many phylogenetic systematists have criticized the Biological Species Concept (BSC) because it distorts evolutionary history. While defenses against this particular criticism have been attempted, I argue that these responses are unsuccessful. In addition, I argue that the source of this problem leads to previously unappreciated, and deeper, fatal objections. These objections to the BSC also straightforwardly apply to other species concepts that are not defined by genealogical history. What is missing from many previous discussions is the fact that the Tree (...) of Life, which represents phylogenetic history, is independent of our choice of species concept. Some species concepts are consistent with species having unique positions on the Tree while others, including the BSC, are not. Since representing history is of primary importance in evolutionary biology, these problems lead to the conclusion that the BSC, along with many other species concepts, are unacceptable. If species are to be taxa used in phylogenetic inferences, we need a history-based species concept. (shrink)

La migración internacional nos enfrenta con problemas irresolubles desde la figura moderna del Estado nacional, su concepto de ciudadanía y su noción de justicia. Juan Carlos Velasco critica las limitaciones y la orientación de las políticas contemporáneas que nos hacen percibir a la migración como una “invasión”, y propone un modo radicalmente diferente de entender e intervenir el fenómeno desde lo trasnacional. Nacer de uno u otro lado de una línea divisoria es un evento azaroso, no obstante delimitar la frontera (...) es una construcción histórico-política: la desigualdad en las oportunidades que ofrecen las naciones es una situación estructural de injusticia que se perpetúa con las políticas de exclusión de los migrantes y la deslegitimación de su derecho a buscar una vida mejor. Esa circunstancia genera fracturas sociales, injustificables pero normalizadas, que imposibilitan alcanzar la justicia global. Velasco presenta un análisis completo que abarca las dimensiones política, jurídica y moral del tema, en el que lleva a la filosofía política a un terreno práctico del que se desprenden las claves para entender y actuar en esta nueva era en la que, debido a los conflictos sociales y políticos, la migración vuelve a ser argumento de discusión relevante.

A common view is that species occupy a unique position on the Tree of Life. Evaluating this claim requires an understanding of what the Tree of Life represents. The Tree represents history, but there are at least three biological levels that are often said to have genealogies: species, organisms, and genes. Here I focus on defending the plausibility of a gene-based account of the Tree. This leads to an account of species that are determined by gene genealogies. On this view, (...) an exclusive group is a group of organisms that forms a clade for a higher proportion of the genome than any conflicting clade. Taxa occupy a unique position in what can be called the ‘primary concordance tree’. But each gene has its own historical ‘Tree of Life’. I conclude by arguing that both organismal pedigrees with their corresponding Tree as well as gene genealogies and their trees are objectively real and play important, but different, roles in biological practice.

A natural starting place for developing a phylogenetic species concept is to examine monophyletic groups of organisms. Proponents of “the” Phylogenetic Species Concept fall into one of two camps. The first camp denies that species even could be monophyletic and groups organisms using character traits. The second groups organisms using common ancestry and requires that species must be monophyletic. I argue that neither view is entirely correct. While monophyletic groups of organisms exist, they should not be equated with species. Instead, (...) species must meet the more restrictive criterion of being genealogically exclusive groups where the members are more closely related to each other than to anything outside the group. I carefully spell out different versions of what this might mean and arrive at a working definition of exclusivity that forms groups that can function within phylogenetic theory. I conclude by arguing that while a phylogenetic species concept must use exclusivity as a grouping criterion, a variety of ranking criteria are consistent with the requirement that species can be placed on phylogenetic trees.

Los escritos de Jürgen Habermas han despertado en España un interés notable y sostenido en el tiempo. Han ejercido una fuerte influencia intelectual no solo en los círculos académicos, sino también en amplios sectores de la esfera pública, algo sorprendente teniendo en cuenta su complejidad y su carácter más bien técnico. En sus textos los lectores españoles han encontrado elementos que sintonizan constructivamente con los cambios acaecidos en su propia sociedad y en el mundo. Como argumento de autoridad o como (...) referencia a rebatir, Habermas se ha hecho habitual en la filosofía y en la teoría social pensada y escrita en español. En este artículo se tratará de presentar los diversos contextos que posibilitaron la acogida de sus ideas, así como los principales actores que con sus trabajos y reflexiones han protagonizado la propagación de su pensamiento.

Bayesian methods have become among the most popular methods in phylogenetics, but theoretical opposition to this methodology remains. After providing an introduction to Bayesian theory in this context, I attempt to tackle the problem mentioned most often in the literature: the “problem of the priors”—how to assign prior probabilities to tree hypotheses. I first argue that a recent objection—that an appropriate assignment of priors is impossible—is based on a misunderstanding of what ignorance and bias are. I then consider different methods (...) of assigning prior probabilities to trees. I argue that priors need to be derived from an understanding of how distinct taxa have evolved and that the appropriate evolutionary model is captured by the Yule birth–death process. This process leads to a well-known statistical distribution over trees. Though further modifications may be necessary to model more complex aspects of the branching process, they must be modifications to parameters in an underlying Yule model. Ignoring these Yule priors commits a fallacy leading to mistaken inferences both about the trees themselves and about macroevolutionary processes more generally. (shrink)

A phylogeny that allows for lateral gene transfer (LGT) can be thought of as a strictly branching tree (all of whose branches are vertical) to which lateral branches have been added. Given that the goal of phylogenetics is to depict evolutionary history, we should look for the best supported phylogenetic network and not restrict ourselves to considering trees. However, the obvious extensions of popular tree-based methods such as maximum parsimony and maximum likelihood face a serious problem—if we judge networks by (...) fit to data alone, networks that have lateral branches will always fit the data at least as well as any network that restricts itself to vertical branches. This is analogous to the well-studied problem of overfitting data in the curve-fitting problem. Analogous problems often have analogous solutions and we propose to treat network inference as a case of model selection and use the Akaike Information Criterion (AIC). Strictly tree-like networks are more parsimonious than those that postulate lateral as well as vertical branches. This leads to the conclusion that we should not always infer LGT events whenever it would improve our fit-to-data, but should do so only when the improved fit is larger than the penalty for adding extra lateral branches.

El propósito principal de este libro es mostrar hasta qué punto el pensamiento teórico de Habermas está animado por un fuerte aliento práctico, más concretamente práctico-político, con el que concretaría el muy ilustrado propósito de hacer uso público de la razón. De hecho, la intencionalidad práctica de su pensamiento es tan destacada que el conjunto de su obra se entiende mucho mejor si se la concibe, tal como él mismo insiste, como un intento de guiar con una finalidad emancipatoria el (...) camino de la praxis, o, si se prefiere, de orientar racionalmente la acción política en las sociedades contemporáneas.

Phylogenetics is the study and reconstruction of evolutionary history and is filled with numerous foundational issues of interest to philosophers. This paper briefly introduces some central concepts in the field, describes some of the main methods for inferring phylogenies, and provides some arguments for the superiority of model-based methods such as Likelihood and Bayesian methods over nonparametric methods such as parsimony. It also raises some underdeveloped issues in the field of interest to philosophers.

Common ancestry is a central feature of the theory of evolution, yet it is not clear what “common ancestry” actually means; nor is it clear how it is related to other terms such as “the Tree of Life” and “the last universal common ancestor”. I argue these terms describe three distinct hypotheses ordered in a logical way: that there is a Tree of Life is a claim about the pattern of evolutionary history, that there is a last universal common ancestor (...) is an ontological claim about the existence of an entity of a specific kind, and that there is universal common ancestry is a claim about a causal pattern in the history of life. With these generalizations in mind, I argue that the existence of a Tree of Life entails a last universal common ancestor, which would entail universal common ancestry, but neither of the converse entailments hold. This allows us to make sense of the debates surrounding the Tree, as well as our lack of knowledge about the last universal common ancestor, while still maintaining the uncontroversial truth of universal common ancestry.

The project of this paper is to understand what a phylogenetic tree represents and to discuss some of the implications that this has for the practice of systematics. At least the first part of this task, if not both parts, might appear trivial—or perhaps better suited for a single page in a textbook rather than a scholarly research paper. But this would be a mistake. While the task of interpreting phylogenetic trees is often treated in a trivial way, their interpretation (...) is tied to foundational conceptual questions at the heart of systematics—questions whose answers are hotly disputed. I have previously argued that widely shared ideas about the meaning and interpretation of phylogenetic trees are inconsistent with species concepts other than some genealogical version of a phylogenetic species concept (Velasco 2008). Here I rely on a similar approach and concentrate on the implications of the necessary conditions underlying the inferences that we make using phylogenetic trees. I argue that common practices for the interpretation and use of trees are in conflict and that unacceptable principles about species as units of phylogeny must be given up. According to the view that I will develop, all phylogenetic trees depict the history of populations. The branches on trees represent collections of population lineages through time and the splits represent population lineage splits. This is true regardless of whether the tips of the trees are themselves populations, or are species or higher taxa. Although this conclusion might be paired naturally with a view that species must be monophyletic groups, this population-centric view of trees is independent of that view of species. If we still want to have species that are paraphyletic groups of populations, this is permissible as long as we also do not treat species as the units of phylogeny. This population-centric view opposes a species-centric view of phylogeny and might be called a “rank-free” approach since it entails that we do not need to determine which groups are species (which is partly a ranking question) in order to build a tree. This conclusion and the argument for it are meant to be consistent with, but not require, acceptance of the conclusions of Velasco (2008) regarding species. (shrink)

[EN] In this article we argue for a world in which open borders are the rule and not the exception. This argument is based on the general recognition of ius migrandi as a basic right of persons. An open-border immigration policy is preferable—at least from a normative standpoint—to the typical policies designed to control or block borders through the simplistic mode of constructing walls. On the basis of a global conception of distributive justice as suggested by cosmopolitan egalitarians, we claim (...) that open-door policies—or, failing in that, the implementation of a system of economic compensation for poor countries—provide powerful means to respond to the enormous inequalities that exist between countries and represent an appropriate way to order current migratory flows. [ES] En este artículo se arguye a favor de un mundo en donde las fronteras abiertas sean la regla y no la excepción. Para ello, se presentan dos tipos de argumentos. El primero se basa en el reconocimiento general del ius migrandi como un derecho fundamental de las personas.

El segundo se asienta sobre una concepción global de la justicia distributiva desarrollada por los igualitaristas cosmopolitas, se sostiene que una política de puertas abiertas –o, en su defecto, un modelo de compensación económica– constituiría un modo de responder a las enormes desigualdades existentes entre los países.

Despite the enormous importance and widespread use of the term, it is unclear exactly what a phylogeny represents. It is important to define phylogeny precisely since other central terms like “clade” and “monophyletic” are often defined relative to phylogenetic trees and on some views in taxonomy, taxa must be clades. Edwards presents the common picture in contemporary systematics as depending on the existence of a “species tree” in which phylogeny “records the branching pattern of evolving lineages through time”. But what, (...) precisely, does this mean? (shrink)

The suppression of trade barriers and liberalization of financial flows inherent to the expansive dynamic of globalization have not extended to international flows of workers. To impede the free movement of workers, restrictive migratory policies have been implemented, and borders have been fortified with walls and fences. In the face of this widespread phenomenon, this chapter presents an alternative consisting of three steps. First, it is noted that in the current migratory context, borders play a key role in reproducing inequalities (...) between countries. Next, it is argued that given the incompatibility of this function with global justice, it is necessary to seek some remedy to put an end to the suffering caused by this structural injustice, a suffering that is endured by an immense number of people unlucky enough to have been born on the wrong side of a border. After presenting a conception of borders that, unlike walls, would enable the movements of people, finally, a scenario is proposed in which the rights of political membership would be reassigned in a cosmopolitan manner and in which borders would usually remain open. Although this does not entail a radical suppression of the aforementioned injustice, its implementation would contribute to not only its reduction but also to the compensation of victims. (shrink)

This chapter introduces and discusses the concepts that are in-depth articulated in the volume. International migration is presented here as a test bench where the normative limits of institutional order, its contradictions and internal tensions are examined. Migrations allows to call into question classical political categories and models. Pointing at walls and fences as tools that reproduce enormous inequalities within the globalized neo-liberal system, this chapter presents the conceptual tensions and contradictions between migration policies and global justice. We challenge the (...) conceptualization of justice as a relationship between citizens of the same country and the State and argue that, in our globalized world, nation-state cannot constitute the basic unit of the theories of justice. We argue that an integral approach that includes the complex and interconnected forms of structural inequalities and transcends the borders of national sovereign states is required. Avoiding the methodological nationalism and the exclusionary biases that inform current migration and border control policies, this chapter finally places attention on the most marginalized subjects of the migration chain: migrant women workers. We point out the importance of addressing transnational structural inequalities and bringing social reproduction to the center of global justice theories. (shrink)

The status of constructivism as a metaethical or metanormative theory is unclear partly due to the lack of a clear semantics for central normative terms such as ‘reason’ and ‘ought’. In a series of recent papers, Sharon Street has attempted to clarify the central commitments of constructivism by focusing on the idea of a practical point of view and what follows from it. We improve upon the informal understanding provided by Street and attempt to provide a semantics for ‘ought’. Our (...) semantics respects the core intuition of the constructivist that normative claims are made true because of our practical commitments as agents and also reflects the constructivist’s commitment to the centrality of practical deliberation to normative truth. On our view, a normative claim of the form ⌜S ought to ϕ⌝ is true if ϕ is entailed from S’s set of evaluative attitudes. We argue that a virtue of our definition is that it allows us to see precisely what is distinctive about constructivism as opposed to realism and expressivism. (shrink)

Common ancestry is one of the pillars of Darwin’s theory of evolution. Today, the Tree of Life, which represents how all life is genealogically related, is often thought of as an essential component in the foundations of biological systematics and so therefore of evolutionary theory – and perhaps all of biology itself. It is an iconic representation in biology and even penetrates into popular culture.

In this paper I address the question of whether the probabilities that appear in models of stochastic gene expression are objective or subjective. I argue that while our best models of the phenomena in question are stochastic models, this fact should not lead us to automatically assume that the processes are inherently stochastic. After distinguishing between models and reality, I give a brief introduction to the philosophical problem of the interpretation of probability statements. I argue that the objective vs. subjective (...) distinction is a false dichotomy and is an unhelpful distinction in this case. Instead, the probabilities in our models of gene expression exhibit standard features of both objectivity and subjectivity. (shrink)

Abstract : In this paper, it is argued that Leibniz’s view that necessity is grounded in the availability of a demonstration is incorrect and furthermore, can be shown to be so by using Leibniz’s own examples of infinite analyses. First, I show that modern mathematical logic makes clear that Leibniz’s "infinite analysis" view of contingency is incorrect. It is then argued that Leibniz's own examples of incommensurable lines and convergent series undermine, rather than bolster his view by providing examples of (...) necessary mathematical truths that are not demonstrable. Finally, it is argued that a more modern view on convergent series would, in certain respects, help support some claims he makes about the necessity of mathematical truths, but would still not yield a viable theory of necessity due to remaining problems with other logical, mathematical, and modal claims.

The volume gathers theoretical contributions on human rights and global justice in the context of international migration. It addresses the need to reconsider human rights and the theories of justice in connection with the transformation of the social frames of reference that international migrations foster. The main goal of this collective volume is to analyze and propose principles of justice that serve to address two main challenges connected to international migrations that are analytically differentiable although inextricably linked in normative terms: (...) to better distribute the finite resources of the planet among all its inhabitants; and to ensure the recognition of human rights in current migration policies. Due to the very nature of the debate on global justice and the implementation of human rights and migration policies, this interdisciplinary volume aims at transcending the academic sphere and appeals to a large public through argumentative reflections. Challenging the Borders of Justice in the Age of Migrations represents a fresh and timely contribution. -/- IN A TIME when national interests are structurally overvalued and borders increasingly strengthened, it’s a breath of fresh air to read a book in which migration flows are not changed into a threat. We simply cannot understand the world around us through the lens of the ‘migration crisis’-a message the authors of this book have perfectly understood. Aimed at a strong link between theories of global justice and policies of border control, this timely book combines the normative and empirical to deeply question the way our territorial boundaries are justified. Professor Ronald Tinnevelt, Radboud University Nijmegen, The Netherlands.- -/- THIS BOOK IS essential reading for those frustrated by the limitations of the dominant ways of thinking about global justice especially in relation to migration. By bringing together discussions of global justice, cosmopolitan political theory and migration, this collection of essays has the potential to transform the way in which we think and debate the critical issues of membership and movement. Together they present a critical interdisciplinary approach to international migration, human rights and global justice, challenging disciplinary borders as well as political ones.

This paper introduces the hypothesis that boredom may be a decisive factor in the social outbreak that took place in Chile in 2019. It is based on another hypothesis that postulates that boredom can become a political emotion capable of unleashing a revolution when it affects an entire community. The main objective of the work is to explain the theoretical, philosophical framework in which the second hypothesis is inscribed and to give reasons why, if this is true, it could be (...) applied to the specific case of Chile. In this sense, an unpublished definition of the concept of boredom is first outlined and the literature that describes boredom as a reactive and political emotion is examined. Then, the Chilean socio-political context of the last forty years is analyzed in search of isolatable factors that may be related to the experience of boredom. Lastly, an original line of research is proposed on which to work to test both hypotheses in a broader project that aims to be able to predict when a social system is on the verge of collapse because of boredom.

Después de hacer un breve recorrido por la cultura española del último siglo, el autor analiza las razones por las que la cultura católica ha pasado en poco tiempo de ser la predominante a encontrarse en retroceso. Para Burgos, la razón principal es la no-elaboración durante el régimen de Franco de una cultura católica moderna que fuera capaz de superar los enormes retos del concilio, el posconcilio y la apertura al pensamiento contemporáneo que tuvo lugar durante la Transición. Ese fracaso (...) condujo a una manifiesta pérdida de influencia en los procesos de configuración social, tendencia que se está agudizando por la imposición de un laicismo excluyente desde instancias gubernativas. Para resolverlo, el autor propone cinco líneas de actuación en el interior de la cultura católica: 1) la plena asunción intelectual del Concilio Vaticano II, es decir, la asunción crítica de la modernidad; 2) la actuación en los mecanismos de socialización contemporánea; 3) la normalización cultural del catolicismo; 4) la promoción de las condiciones adecuadas para la creatividad, y 5) el conocimiento y difusión de lo propio.

Argumentar constituye un quehacer cotidiano para los diferentes operadores jurídicos y, de modo especial, para quienes desempeñan la función judicial. Dado que las decisiones de los jueces están sometidas a un cierto control de racionalidad, es posible concebir las argumentaciones jurídicas empleadas en la aplicación del derecho como un modo institucionalizado de ejercitar la racionalidad práctica. Sin embargo, esto no implica, en contra de lo que a menudo se suele afirmar, que los procesos argumentatívos jurídicos estén sujetos en exclusiva a (...) las leyes de la lógica deductiva. Cabe sostener el carácter racional de la aplicación del derecho sin caer en un logicísmo a ultranza ni en una defensa de las artes de la retórica y de la tópica: ahí está, entre otras, la vía defendida por la teoría discursiva de la argumentación jurídica elaborada por Robert Alexy a partir de presupuestos básicamente habermasianos, así como las correcciones contextualistas de la misma llevadas a cabo por Klaus Günthcr.
