Empleando procedimientos de la lógica simbólica, se intenta contribuir a una mejor comprensión del ejercicio dialéctico llevado a cabo en el Parménides. La interpretación de las formas del ser y el no ser a partir de la oposición entre el objeto de conocimiento y el pensamiento acerca del mismo, abre la puerta a una manera original de enfocar el problema de la verdad en Platón. Puede resultar interesante, asimismo, la solución que se propone a la aporía planteada en Parménides 132b-c, (...) relativa a la confusión del pensamiento o el no ser con otras formas. (shrink)

This paper provides an original approach to research on the logical processes that determine how certain forms participate in others. By introducing the concept of relational participation, the problems of self-referentiality of the Platonic forms can be dealt with more effectively. Applying this to the forms of likeness and unlikeness in Parmenides 132d-133a reveals a possible way to resolve different versions of the Third Man Argument. The method of generating numbers from oddness and evenness may also be of interest; relational (...) participation in these forms clarifies the interpretation of Parmenides 143e-144a. (shrink)

We develop some of Williamson’s ideas regarding how propositional calculus aids in comprehending Aristotelian logic. Specifically, we enhance the utilisation of truth tables to examine the structure of opposition diagrams. Using ‘conditioned truth tables’, we establish logical dependency relationships between the truth values of different propositions. This approach proves effective in interpreting various texts of the Organon concerning the doctrine of opposition.

Eternalism is the view that all times are equally real. The relativity of simultaneity in special relativity backs this up. There is no cosmically extended, self-existing ‘now.’ This leads to a tricky problem. What makes statements about the present true? I shall approach the problem along the lines of perspectival realism and argue that the choice of the perspective does. To corroborate this point, the Lorentz transformations of special relativity are compared to the structurally similar equations of the Doppler effect. (...) The ‘now’ is perspectivally real in the same way as a particular electromagnetic spectrum frequency. I also argue that the ontology of time licensed by perspectival realism is more credible in this context than its current alternative, the fragmentalist interpretation of special relativity.

For the last forty years, Hume's Newtonianism has been a debated topic in Hume scholarship. The crux of the matter can be formulated by the following question: Is Hume a Newtonian philosopher? Debates concerning this question have produced two lines of interpretation. I shall call them ‘traditional’ and ‘critical’ interpretations. The traditional interpretation asserts that there are many Newtonian elements in Hume, whereas the critical interpretation seriously questions this. In this article, I consider the main points made by both lines (...) of interpretations and offer further arguments that contribute to this debate. I shall first argue, in favor of the traditional interpretation, that Hume is sympathetic to many prominently Newtonian themes in natural philosophy such as experimentalism, criticality of hypotheses, inductive proof, and criticality of Leibnizian principles of sufficient reason and intelligibility. Second, I shall argue, in accordance with the critical interpretation, that in many cases Hume... (shrink)

Eternalism is the view that the past, the present and the future exist simpliciter. A typical argument in favor of this view leans on the relativity of simultaneity. The ‘equally real with’ relation is assumed to be transitive between spacelike separated events connected by hyperplanes of simultaneity. This reasoning is in tension with the conventionality of simultaneity. Conventionality indicates that, even within a specific frame, simultaneity is based on the choice of the synchronization parameter. Hence the argument for eternalism is (...) compromised. This paper lays out alternative eternalist strategies which do not hinge on hyperplanes. While we lack a rigorous proof for eternalism, there are still cogent reasons to prefer eternalism over presentism. (shrink)

A central debate in the current philosophical literature on temporal experience is over the following question: do temporal experiences themselves have a temporal structure that mirrors their temporal contents? Extensionalists argue that experiences do have a temporal structure that mirrors their temporal contents. Atomists insist that experiences don’t have a temporal structure that mirrors their contents. In this paper, I argue that this debate is misguided. Both atomism and extensionalism, considered as general theories of temporal experience, are false, since temporal (...) experience is not a single undifferentiated phenomena as both theories require. I argue for this conclusion in two steps. First, I show that introspection cannot settle the debate. Second, I argue that the neuroscientific evidence is best read as revealing a host of mechanisms involved in temporal perception - some admitting of an extensionalist interpretation while others admitting only of an atomistic interpretation. As a result, neither side of the debate wins. (shrink)

This article investigates the relationship between Hume’s causal philosophy and Newton ’s philosophy of nature. I claim that Newton ’s experimentalist methodology in gravity research is an important background for understanding Hume’s conception of causality: Hume sees the relation of cause and effect as not being founded on a priori reasoning, similar to the way that Newton criticized non - empirical hypotheses about the properties of gravity. However, according to Hume’s criteria of causal inference, the law of universal gravitation is (...) not a complete causal law, since it does not include a reference either to contiguity or to temporal priority. It is still argued that because of the empirical success of Newton ’s theory—the law is a statement of an exceptionless repetition—Hume gives his support to it in interpreting gravity force instrumentally as if it bore a causal relation to motion.

We argue that animals are not cognitively stuck in time. Evidence pertaining to multisensory temporal order perception strongly suggests that animals can represent at least some temporal relations of perceived events.

The state of our current world has brought about a very active discussion concerning possible alternatives to our current society. In this article, I wish to consider Marx’s idea of communism as a possible alternative, by understanding it as an undetermined concept that only proposes a society without classes and private property. The thesis I will defend here is that we can meaningfully think about such an alternative through the means of Science Fiction literature. In particular, I will take Ursula (...) Le Guin’s The Dispossessed (2006) as a case study. To clarify this relation between science fiction (SF) literature and communism as a particular case of an alternative society, I will introduce some concepts of Edmund Husserl’s phenomenological theory. Thus, I shall argue that in SF we can presentify in bounded phantasy an alternative lifeworld, so furnishing with content the undetermined idea, and in doing so, strengthen the belief in the possibility of such an alternative society.

El lenguaje o la actividad cognoscitiva del ser humano que se debate en su lucha contra la circunstancia en la que le ha tocado vivir es hablar, decir y conocer. El hombre habla porque tiene algo que decir, dice porque se define a sí mismo ante la circunstancia en la que vive en cada momento, y esto es posible porque conoce de forma creativa. En este sentido el decir determina el hablar, por arriba, y el conocer por abajo. El conocer (...) humano empieza en una sensación sensible, la aísthesis, la cual es transformada en un universal, extracto o concepto, logos, el cual es el fruto de una serie de operaciones intelectivas realizadas por el propio sujeto en u solo acto, el acto único de hablar, decir y conocer.

Given the sharp distinction that follows from Hume’s Fork, the proper epistemic status of propositions of mixed mathematics seems to be a mystery. On the one hand, mathematical propositions concern the relation of ideas. They are intuitive and demonstratively certain. On the other hand, propositions of mixed mathematics, such as in Hume’s own example, the law of conservation of momentum, are also matter of fact propositions. They concern causal relations between species of objects, and, in this sense, they are not (...) intuitive or demonstratively certain, but probable or provable. In this article, I argue that the epistemic status of propositions of mixed mathematics is that of matters of fact. I wish to show that their epistemic status is not a mystery. The reason for this is that the propositions of mixed mathematics are dependent on the Uniformity Principle, unlike the propositions of pure mathematics. (shrink)

It’s often claimed in the philosophical and scientific literature on temporal representation that there is no such thing as a genuine sensory system for time. In this paper, I argue for the opposite—many animals, including all mammals, possess a genuine sensory system for time based in the circadian system. In arguing for this conclusion, I develop a semantics and meta-semantics for explaining how the endogenous rhythms of the circadian system provide organisms with a direct information link to the temporal structure (...) of their environment. In doing so, I highlight the role of sensory systems in an information processing architecture. (shrink)

According to a widespread view, Einstein’s definition of time in his special relativity is founded on the positivist verification principle. The present paper challenges this received outlook. It shall be argued that Einstein’s position on the concept of time, to wit, simultaneity, is best understood as a mitigated version of concept empiricism. He contrasts his position to Newton’s absolutist and Kant’s transcendental arguments, and in part sides with Hume’s and Mach’s empiricist arguments. Nevertheless, Einstein worked out a concept empiricism that (...) is considerably more moderate than what we find in the preceding empiricist tradition and early logical positivism. He did not think that the origin of concepts is in observations, but in conventions, and he also maintained a realist ontology of physical events, which he thought is necessary for his theory. Consequently, his philosophy of time in special relativity is not couched in terms of an anti-metaphysical verificationism. (shrink)

I argue that a standard formulation of hinge epistemology is host to epistemic relativism and show that two leading hinge approaches (Coliva’s acceptance account and Pritchard’s nondoxastic account) are vulnerable to a form of incommensurability that leads to relativism. Building on both accounts, I introduce a new, minimally epistemic conception of hinges that avoids epistemic relativism and rationally resolves hinge disagreements. According to my proposed account, putative cases of epistemic incommensurability are rationally resolvable: hinges are propositions that are the objects (...) of our belief-like attitudes and are rationally revisable in virtue of our overarching commitment to avoid systematic deception in our epistemic practices.

El objetivo de este trabajo es examinar el diagnóstico crítico que Rahel Jaeggi realiza de la sociedad. El trabajo comienza desarrollando el análisis que lleva a cabo de la crítica de la ideología. Luego mostraremos los elementos centrales de su teoría crítica desplegados en Alienación y Crítica de las formas de vida. La conclusión es que la teoría crítica de Jaeggi es una crítica inmanente y una crítica de la ideología de la sociedad contemporánea.

Various writers have attempted to use the sender-receiver formalism to account for the representational capacities of biological systems. This paper has two goals. First, I argue that the sender-receiver approach to representation cannot be complete. The mammalian circadian system represents the time of day, yet it does not control circadian behaviours by producing signals with time of day content. Informative signalling need not be the basis of our most basic representational capacities. Second, I argue that representational capacities are primarily about (...) control, and only when specific conditions obtain does this control require informative signalling. (shrink)

I shall argue that when Hume refers to the laws of dynamics, he tacitly assumes a mechanism. Nevertheless, he remains agnostic on whether the hidden micro-constitution of bodies is machinelike. Hence this article comes to the following conclusion. Hume is not a full-blown mechanical philosopher. Still his position on dynamic laws and his concept of causation instantiate a tacitly mechanical understanding of the interactions of bodies.

This book defends a relational theory of the passage of time. The realist view of passage developed in this book differs from the robust, substantivalist position. According to relationism, passage is nothing over and above the succession of events, one thing coming after another. Causally related events are temporally arranged as they happen one after another along observers’ worldlines. There is no unique global passage but a multiplicity of local passages of time. After setting out this positive argument for relationism, (...) the author deals with five common objections to it: (a) triviality of deflationary passage, (b) a-directionality of passage, (c) the impossibility of experiencing passage, (d) fictionalism about passage, and (e) the incompatibility of passage with perduring objects.

Although the main focus of Hume’s career was in the humanities, his work also has an observable role in the historical development of natural sciences after his time. To show this, I shall center on the relation between Hume and two major figures in the history of the natural sciences: Charles Darwin (1809–1882) and Albert Einstein (1879–1955). Both of these scientists read Hume. They also found parts of Hume’s work useful to their sciences. Inquiring into the relations between Hume and (...) the two scientists shows that his philosophical positions had a partial but constructive role in the formation of modern biology and physics. This is accordingly a clear indication of Hume’s impact on the scientific tradition. Before proceeding to analyze Hume’s contribution to the history of science, it is important to address his broader role in the history of philosophy of science. Hume’s discussions concerning the topics of causation, induction, the distinction between mathematical and empirical propositions, and laws of nature have been important for the philosophy of science of the nineteenth and twentieth centuries.

This article centers on Hume’s position on the intelligibility of natural philosophy. To that end, the controversy surrounding universal gravitation shall be scrutinized. It is very well-known that Hume sides with the Newtonian experimentalist approach rather than with the Leibnizian demand for intelligibility. However, what is not clear is Hume’s overall position on the intelligibility of natural philosophy. It shall be argued that Hume declines Leibniz’s principle of intelligibility. However, Hume does not eschew intelligibility altogether; his concept of causation itself (...) stipulates mechanical intelligibility. (shrink)

This book contextualizes David Hume's philosophy of physical science, exploring both Hume's background in the history of early modern natural philosophy and its subsequent impact on the scientific tradition.

Einstein acknowledged that his reading of Hume influenced the development of his special theory of relativity. In this article, I juxtapose Hume’s philosophy with Einstein’s philosophical analysis related to his special relativity. I argue that there are two common points to be found in their writings, namely an empiricist theory of ideas and concepts, and a relationist ontology regarding space and time. The main thesis of this article is that these two points are intertwined in Hume and Einstein.

Ajan luonnetta koskevissa käsityksissä on tyypillistä erottaa kaksi eriävää kantaa: A-teoreettinen presentismi ja B-teoreettinen eternalismi. Edeltävän väitetään tyypillisesti sopivan yhteen inhimillisen ajallisen kokemuksen kanssa ja jälkimmäisen ontologisesti perustavanlaatuisen luonnontieteen kanssa. Ilmikuvamme ajasta sisältää ehdottoman nykyisyyden ja yksisuuntaisen ajan kulun menneestä tulevaan. Tieteellinen kuva ajasta ei sisällä erityistä nykyisyyttä eikä ajan kulun edellyttämää dynaamista aikamuotojen muutosta. Monet ovat pitäneet kokemustamme ajan kulusta illuusiona. Tässä artikkelissa keskitytään A-sarjan mukaisen ajankulun virheteoreettiseen tulkintaan. Tarkastellaan mahdollisuutta, jonka mukaan meillä ei ole kyseistä kokemusta vaan kuvailemme (...) kokemustamme virheellisesti ajan virtaukseen liittyvillä vertauskuvilla. Tätä tukee fysikalistinen argumentti: Jos ajan kulun kokemuksellamme ei ole fysikaalista perustaa, meillä ei voi olla sen mukaista kokemustakaan ajasta. (shrink)

I argue that Hume’s philosophy of time is relationist in the following two senses. 1) Standard definition of relationism. Time is a succession of indivisible moments. Hence there is no time independent of change. Time is a relational, not substantial feature of the world. 2) Rigid relationism. There is no evidence of uniform natural standard for synchronization of clocks. No absolute temporal metric is available. There are countless times, and no time is privileged. Combining 1) and 2) shows that Hume’s (...) ontology of time is thoroughly relationist. (shrink)

This essay explores Kaila's interpretation of the special theory of relativity. Although the relevance of his work to logical empiricism is well-known, not much has been written on what Kaila calls the ‘Einstein-Minkowski invariance theory’. Kaila's interpretation focuses on two salient features. First, he emphasizes the importance of the invariance of the spacetime interval. The general point about spacetime invariance has been known at least since Minkowski, yet Kaila applies his overall tripartite theory of invariances to space, time and spacetime (...) in an original way. Second, Kaila provides a non-conventionalist argument for the isotropic speed of electromagnetic signals. The standard Einstein synchrony is not a mere convention but a part of a larger empirical theory. According to Kaila's holistic principle of testability, which stands in contrast to the theses of translatability and verification, different items in the theory cannot be sharply divided into conventional and empirical. Kaila's invariantism/non-conventionalism about relativity reflects an interesting case in the gradual transition from positivism to realism within the philosophy of science. (shrink)

In this paper, we try to understand how Bunge’s scientific hylorealism can fit with several crystal chemistry’s objects and their properties. It is found that many of them, lying at the very core of this discipline, bring support to ontologi-cal emergentism.

Este ensayo acomete un análisis del concepto de fantasmagoría en el marco de los materiales del proyecto inacabado del Libro de los pasajes de Walter Benjamin. Para ello, parte de la relación que en ellos se traza entre este término y el carácter fetichista que Marx atribuye a la mercancía, a fin de mostrar cómo dicho carácter, así como la noción de ideología que se segrega de él, constituyen el fundamento de la utilización por parte de Benjamin del concepto de (...) fantasmagoría. Sobre esta base, se defiende que el sentido que Benjamin confiere a esta noción implica una ampliación del concepto marxiano de ideología que obedecería a un doble objetivo: incluir bajo su alcance aspectos de la autocomprensión de la sociedad moderna no tematizados por Marx y adaptarlo a los resultados de la evolución del capitalismo. Por último, se estudia la conexión que la noción de fantasmagoría guarda con lo que Benjamin llama el «despertar» en el contexto de su reflexión sobre la tarea del historiador materialista. (shrink)

The aim of this paper is to investigate the relations between knowledge, language and communication within the framework of Neurath's philosophical and political program. In particular, we draw a parallel between the adoption of the physicalist language as the basic language of science and the development of ISOTYPE system of visual education. We defend the idea that they maintain a relation of reciprocity with each other that makes possible the exchange of factual information and the transformation of verbal statements into (...) visual statements, and vice versa. This relation of reciprocity is also based on a series of shared features. In this regard, we consider that both are conceived as thing-languages and both play a pedagogical and political role, that consists in enabling communication between science and society. For Neurath, this role also involves a model of communication aimed at the humanization of knowledge and the democratization of decisions. (shrink)

Taiwan and Vietnam have taken successful measures to combat the spread of COVID-19 at the early stages. Many authors attributed the successful policies to the lessons learned by these countries during the severe acute respiratory syndrome (SARS) pandemic in 2002.(Ohara, 2004) This manuscript provides a summary of recent early-stage policies that were successful in mitigating the spread and creating resilience against the negative consequences of COVID-19 in Taiwan and Vietnam. Crucially, these policies go beyond and complement social isolation. As social (...) isolation is expected to have a negative socio-economic impact on the population and adherence is likely to decrease with time(Armitage and Nellums, 2020; Weems et al., 2020), it is important to consider a broad range of policies to promote a steady control of the COVID-19 spread. Initially, we provide a brief introduction to some general concepts related to COVID-19. Thereafter, we introduce a concise review of policies and their dates relative to the first detection case in Taiwan and Vietnam as well as doing a comparative analysis. (shrink)

En su libro Una ética sin fundamentos, Nicolás Zavadivker sostiene que la teoría ética y metaética de Mario Bunge pretende fundamentar las normas morales en premisas fácticas, sin hacer uso de valores.

Dado que la teoría de Bunge incluye valores entre (...) sus premisas argumentativas, es incorrecto categorizarla como una posición fundacionista que prescinde de valores. (shrink)

Existen conceptos clave en las diversas ciencias (ya sean formales, naturales, biosociales o sociales) como “teoría” o “modelo” que están aún hoy sujetos a un amplio debate epistemológico, i.e. desde la teoría del conocimiento, y centrada en el estudio del conocimiento científico en particular.

I argue against the Standard View of ignorance, according to which ignorance is defined as equivalent to lack of knowledge, that cases of environmental epistemic luck, though entailing lack of knowledge, do not necessarily entail ignorance. In support of my argument, I contend that in cases of environmental luck an agent retains what I call epistemic access to the relevant fact by successfully exercising her epistemic agency and that ignorance and non-ignorance, contrary to what the Standard View predicts, are not (...) modal in the sense that knowledge is. After responding to objections, I conclude by sketching an alternative account of ignorance centered on the notions of epistemic access and epistemic agency. (shrink)

Dans cet article, nous essayons de comprendre comment l’hyloréalisme scientifique de Bunge peut s’accommoder avec plusieurs objets de la chimie des cristaux et leurs propriétés.

Linguistics of Saying is to be analyzed in the speech act conceived as an act of knowing. The speaking, saying and knowing subject, based on contexts and the principles of congruency and trust in the speech of other speakers, will create meanings and interpret the sense of utterances supplying the deficiencies of language by means of the intellective operations mentally executed in the act of speech. In the intellective operations you can see three steps or processes: first the starting point, (...) intuition or aísthesis; second, the process of abstraction; and third, the inverse: the process of determination or fixing the construct created.

Linguistics of saying studies language in its birth. Language is the mental activity executed by speaking subjects. Linguistics of saying consists in analyzing speech acts as the result of an act of knowing. Speaking subjects speak because they have something to say. Tthey say because they define themselves before the circumstance they are in. And this is possible because they are able to know. Speaking, then, is speaking, saying and knowing. In this sense there is a progressive determination. Knowing makes (...) possible saying, and saying determines speaking, or, in other words: speaking involves saying and knowing, and saying involves knowing. The problem thus is to determine the meaningful intentional purpose of the individual speaker to say something in every speech act. (shrink)

To provide metaphysical grounds for the physics of her time, Du Châtelet argued for the notion of an active force. This was different from the impressed force in Newton’s second law. The former force was a property of a body, whereas the latter was an external cause.

Consequently, the interaction entailed by the law (...) of universal gravitation complies with Du Châtelet’s principles of human knowledge. (shrink)

We may distinguish two interpretations of the relation between Newton’s natural philosophy and Hume’s science of human nature. The first interpretation can be called ‘traditional,’ the second ‘critical.’ This article will not side with either readings of Hume’s Newtonianism (or with some middle positions). Instead, essential points of confluence and divergence will be discussed.

According to componential theories of emotional experience, emotional experiences are phenomenally complex in that they consist of experiential parts, which may include cognitive appraisals, bodily feelings, and action tendencies. These componential theories face the problem of emotional unity: Despite their complexity, emotional experiences also seem to be phenomenologically unified. Componential theories have to give an account of this unity. We argue that existing accounts of emotional unity fail and that instead emotional unity is an instance of experienced causal‐temporal unity. We (...) propose that felt emotional unity arises from our experience of the temporal‐causal order of the world. (shrink)

Este artigo apresenta um quadro conceitual para examinar a questão do especismo. Começa definindo-o como a consideração ou tratamento desfavorável injustificado daqueles que não pertencem a uma determinada espécie. A seguir, esclarece alguns dos mal-entendidos comuns acerca do que é e do que não é o especismo. Depois disso, argumenta contra a confusão entre (1) os diferentes modos em que se pode defender o especismo; e (2) as diferentes posições que assumem o especismo como uma de suas premissas. Dependendo se (...) essas últimas aceitam ou não outros critérios para a consideração moral à parte do especismo, podem ser posições especistas simples ou combinadas.

O conceito de antropocentrismo difere do de especismo e do de misoteria (animadversão para com os animais não humanos). Não obstante, pode-se concluir que o antropocentrismo é uma forma de especismo, à luz do que indicam, entre outros, o argumento da sobreposição de espécies e o argumento da relevância. (shrink)

Whipple disease is a rare, infectious, disease first described from a single case by Whipple in 1907. As well as characterising the clinical and pathological features of the condition, Whipple made two suggestions regarding its aetiology. These were either than the disease was caused by an infectious agent, or that it was of metabolic origin. As the disease is now thought to be caused by infection with the bacterium Tropheryma whipplei, historical reviews of the history of the disease typically mention (...) only the first of these suggestions. In this paper, we therefore revisit Whipple’s other theory. We argue that a diverse and often successful research programme was developed around this mechanism of disease causation which gave rise to many useful findings on the condition. In the later parts of this article, we then turn to discuss the surprising neglect of this period of Whipple disease research in the current literature, and conclude by offering a brief reconstruction of this early history suitable for use in a technical context.

Language is nothing but human subjects in as much as they speak, say and know. Language is something coming from the inside of the speaking subject manifest in the intentional meaningful purpose of the individual speaker. A language, on the contrary, is something coming from the outside, from the speech community, something offered to the speaking subject from the tradition in the technique of speaking. The speech act is the performance of an intuition by the subject, both individual and social.

The subject of this essay-based dissertation is Hume’s natural philosophy. The dissertation consists of four separate essays and an introduction. These essays do not only treat Hume’s views on the topic of natural philosophy, but his views are placed into a broader context of history of philosophy and science, physics in particular. The introductory section outlines the historical context, shows how the individual essays are connected, expounds what kind of research methodology has been used, and encapsulates the research contributions of (...) the essays. The first essay treats Newton’s experimentalist methodology in gravity research and its relation to Hume’s causal philosophy. It is argued that Hume does not see the relation of cause and effect as being founded on a priori reasoning, similar to the way in which Newton criticized non-empirical hypotheses about the causal properties of gravity. Contrary to Hume’s rules of causation, the universal law does not include a reference either to contiguity or succession, but Hume accepts it in interpreting the force and the law of gravity instrumentally. The second article considers Newtonian and non-Newtonian elements in Hume more broadly. He is sympathetic to many prominently Newtonian themes in natural philosophy, such as experimentalism, critique of hypotheses, inductive proof, and the critique of Leibnizian principles of sufficient reason and intelligibility. However, Hume is not a Newtonian philosopher in many respects: his conceptions regarding space and time, the vacuum, the specifics of causation, the status of mechanism, and the reality of forces differ markedly from Newton’s related conceptions. The third article focuses on Hume’s Fork and the proper epistemic status of propositions of mixed mathematics. It is shown that the epistemic status of propositions of mixed mathematics, such as those concerning laws of nature, is that of matters of fact. The reason for this is that the propositions of mixed mathematics are dependent on the Uniformity Principle. The fourth article analyzes Einstein’s acknowledgement of Hume regarding special relativity. The views of the scientist and the philosopher are juxtaposed, and it is argued that there are two common points to be found in their writings, namely an empiricist theory of ideas and concepts and a relationist ontology regarding space and time.

In this paper, we argue that the All Affected Principle generates a puzzle when applied to carbon tax referendums. According to recent versions of the All Affected Principle, people should have a say in a democratic decision in positive proportion to how much the decision affects them. Plausibly, one way of being affected by a carbon tax referendum is to bear the economic burden of paying the tax. On this metric of affectedness, then, people who pollute a lot are ceteris (...) paribus more affected than people who don’t, because the former stands to pay more in carbon taxes than the latter. Consequently, people who pollute a lot receive large voting power, while people who pollute a little receive little voting power. This is a puzzling distribution of voting power for several reasons. First, it is instrumentally counterproductive if the goal is to rectify damages to the climate. Second, it introduces prudential incentives for everyone to pollute more to gain voting power. Third, the relative difference in voting power between people who pollute a lot and people who don’t is puzzling from a desert-based point of view, since the former often make a serious effort to avoid polluting, while the latter don’t.

Category-based induction is an inferential mechanism that uses knowledge of conceptual relations in order to estimate how likely is for a property to be projected from one category to another. During the last decades, psychologists have identified several features of this mechanism, and they have proposed different formal models of it. In this article; we propose a new mathematical model for category-based induction based on distances on conceptual spaces. We show how this model can predict most of the properties of (...) this kind of reasoning while providing a solid theoretical foundation for it. We also show that it subsumes some of the previous models proposed in the literature and that it generates new predictions. (shrink)

We claim that scientists working with deep learning (DL) models exhibit a form of pragmatic understanding that is not reducible to or dependent on explanation. This pragmatic understanding comprises a set of learned methodological principles that underlie DL model design-choices and secure their reliability. We illustrate this action-oriented pragmatic understanding with a case study of AlphaFold2, highlighting the interplay between background knowledge of a problem and methodological choices involving techniques for constraining how a model learns from data. Building successful models (...) requires pragmatic understanding to apply modelling strategies that encourage the model to learn data patterns that will facilitate reliable generalisation. (shrink)
