How to accept a conditional? F. P. Ramsey proposed the following test in (Ramsey 1990).(RT) If A, then B must be accepted with respect to the current epistemic state iff the minimal hypothetical change of it needed to accept A also requires accepting B.

People increasingly form beliefs based on information gained from automatically filtered Internet ‎sources such as search engines. However, the workings of such sources are often opaque, preventing ‎subjects from knowing whether the information provided is biased or incomplete. Users’ reliance on ‎Internet technologies whose modes of operation are concealed from them raises serious concerns about ‎the justificatory status of the beliefs they end up forming. Yet it is unclear how to address these concerns ‎within standard theories of knowledge and justification. (...) To shed light on the problem, we introduce a ‎novel conceptual framework that clarifies the relations between justified belief, epistemic responsibility, ‎action, and the technological resources available to a subject. We argue that justified belief is subject to ‎certain epistemic responsibilities that accompany the subject’s particular decision-taking circumstances, ‎and that one typical responsibility is to ascertain, so far as one can, whether the information upon which ‎the judgment will rest is biased or incomplete. What this responsibility comprises is partly determined by ‎the inquiry-enabling technologies available to the subject. We argue that a subject’s beliefs that are ‎formed based on Internet-filtered information are less justified than they would be if she either knew how ‎filtering worked or relied on additional sources, and that the subject may have the epistemic ‎responsibility to take measures to enhance the justificatory status of such beliefs.‎.

Conceptual engineering is commonly characterized as the method for assessing and improving our representational devices. Little has been said, however, on how best to construe these representational devices—in other words, on what conceptual engineering should be all about. This paper tackles this problem with a basic strategy: First, by presenting a taxonomy of the different possible subject matters for conceptual engineering; then, by comparatively assessing them and selecting the most conducive one with a view to making conceptual engineering an actionable (...) method, that is, a method that can be applied effectively and consistently to specific case studies. The outcome is that conceptual engineering should be all about concepts on pain of pragmatic inconsistencies otherwise. (shrink)

Information providing and gathering increasingly involve technologies like search ‎engines, which actively shape their epistemic surroundings. Yet, a satisfying account ‎of the epistemic responsibilities associated with them does not exist. We analyze ‎automatically generated search suggestions from the perspective of social ‎epistemology to illustrate how epistemic responsibilities associated with a ‎technology can be derived and assigned. Drawing on our previously developed ‎theoretical framework that connects responsible epistemic behavior to ‎practicability, we address two questions: first, given the different technological ‎possibilities available (...) to searchers, the search technology, and search providers, ‎who should bear which responsibilities? Second, given the technology’s ‎epistemically relevant features and potential harms, how should search terms be ‎autocompleted? Our analysis reveals that epistemic responsibility lies mostly with ‎search providers, which should eliminate three categories of autosuggestions: those ‎that result from organized attacks, those that perpetuate damaging stereotypes, and ‎those that associate negative characteristics with specific individuals.‎.

In this paper I offer an analysis of Plotinus’ argument for the existence of a quasi-psychic entity, the so-called ‘trace of soul’, that functions as an immanent cause of life for an organism’s body. I argue that Plotinus posits this entity primarily in order to account for the body’s possession of certain quasi-psychic states that are instrumental in his account of soul-body interaction. Since these quasi-psychic states imply that an organism’s body has vitality of its own , and Platonic souls (...) are no part or aspect of any body, Plotinus draws the conclusion that the soul must be a cause of the body’s life by imparting a quasi-psychic qualification to it. In so doing, Plotinus introduces elements of hylomorphism into Platonist psychology, and addresses a problem for the animation of the body that Platonic soul-body dualism may plausibly be thought to face.

We study thorn forking and rosiness in the context of continuous logic. We prove that the Urysohn sphere is rosy (with respect to finitary imaginaries), providing the first example of an essentially continuous unstable theory with a nice notion of independence. In the process, we show that a real rosy theory which has weak elimination of finitary imaginaries is rosy with respect to finitary imaginaries, a fact which is new even for discrete first-order real rosy theories.

Mechanism realists assert the existence of mechanisms as objective structures in the world, but their exact metaphysical commitments are unclear. We introduce Local Hierarchy Realism (LHR) as a substantive and plausible form of mechanism realism. The limits of LHR reveal a deep tension between two aspects of mechanists’ explanatory strategy. Functional decomposition identifies locally relevant entities and activities, while these same entities and activities are also embedded in a nested hierarchy of levels. In principle, a functional decomposition may identify entities (...) engaging in causal interactions that crosscut the hierarchical structure of composition relations, violating the mechanist’s injunction against interlevel causation. We argue that this possibility is realized in the example of ephaptic coupling, a subsidiary process of neural computation that crosscuts the hierarchy derived from synaptic transmission. These considerations undermine the plausibility of LHR as a general view, yet LHR has the advantages that (i) its metaphysical implications are precisely stateable; (ii) the structure it identifies is not reducible to mere aggregate causation; and (iii) it clearly satisfies intuitive and informal definitions of mechanism. We conclude by assessing the prospects for a form of mechanism realism weaker than LHR that nevertheless satisfies all three of these requirements. (shrink)

The present paper shows how one might model Everettian quantum mechanics using hyperfinitely many worlds. A hyperfinite model allows one to consider idealized measurements of observables with continuous-valued spectra where different outcomes are associated with possibly infinitesimal probabilities. One can also prove hyperfinite formulations of Everett’s limiting relative-frequency and randomness properties, theorems he considered central to his formulation of quantum mechanics. Finally, this model provides an intuitive framework in which to consider no-collapse formulations of quantum mechanics more generally.

The paper includes a series of letters exchanged between the author and the late Professor Feyerabend, concerning the best "method" for military intelligence, as a test case for the role of conceptual frameworks in philosophy of science. The letters deal with issues like: Is it possible to make an intelligence estimate without a conceptual framework? Does such a framework have any 'positive' role? If so, how should a conceptual framework in intelligence be built? What risks lurk within it? Is it (...) possible to indicate methods for intelligence estimates which are 'better' and more 'successful' than others? (shrink)

A foundational idea of evo‐devo is that morphological variation is not isotropic, that is, it does not occur in all directions. Instead, some directions of morphological variation are more likely than others from DNA‐level variation and these largely depend on development. We argue that this evo‐devo perspective should apply not only to morphology but to evolution at all phenotypic levels. At other phenotypic levels there is no development, but there are processes that can be seen, in analogy to development, as (...) constructing the phenotype (e.g., protein folding, learning for behavior, etc.). We argue that to explain the direction of evolution two types of arguments need to be combined: generative arguments about which phenotypic variation arises in each generation and selective arguments about which of it passes to the next generation. We explain how a full consideration of the two types of arguments improves the explanatory power of evolutionary theory. Also see the video abstract here: https://youtu.be/Egbvma_uaKc. (shrink)

In developing his theory of aether in De Caelo 1, Aristotle argues, in DC 1.4, that one circular motion cannot be contrary to another. In this paper, I discuss how Aristotle can maintain this position and accept the existence of celestial spheres that rotate in contrary directions, as he does in his revision of the Eudoxan theory in Metaphysics 12.8.

We present a decision-theoretically motivated notion of contraction which, we claim, encodes the principles of minimal change and entrenchment. Contraction is seen as an operation whose goal is to minimize loses of informational value. The operation is also compatible with the principle that in contracting A one should preserve the sentences better entrenched than A (when the belief set contains A). Even when the principle of minimal change and the latter motivation for entrenchment figure prominently among the basic intuitions in (...) the works of, among others, Quine and Ullian (1978), Levi (1980, 1991), Harman (1988) and Gärdenfors (1988), formal accounts of belief change (AGM, KM – see Gärdenfors (1988); Katsuno and Mendelzon (1991)) have abandoned both principles (see Rott (2000)). We argue for the principles and we show how to construct a contraction operation, which obeys both. An axiom system is proposed. We also prove that the decision-theoretic notion of contraction can be completely characterized in terms of the given axioms. Proving this type of completeness result is a well-known open problem in the field, whose solution requires employing both decision-theoretical techniques and logical methods recently used in belief change.

Una respuesta al debate metafilosófico sobre si hay o no unos criterios regulativos en filosofía cómo área de investigación lo ofrece la denominada filosofía sintética. Dentro de esta posición se propone una forma de abordar toda la filosofía y teorizar en base a diferentes criterios propuestos, que suelen ser generalmente: la claridad semántica, la coherencia interna, la coherencia externa con las ciencias y la fecundidad teórica con otros campos de estudio. Estos criterios de corte naturalista a su vez se ofrecen (...) como debatibles y ampliables a otros criterios. Se razonará la necesidad de demarcar la filosofía, y, poniendo el foco en su metodología, se argumentarán los previos criterios con tal de fomentar la filosofía sintética como marco general de trabajo filosófico riguroso. Esto excluye de la disciplina tanto aquello que no sea filosófico como aquello que intente emular la filosofía sin serlo en verdad, la pseudofilosofía. (shrink)

The 2015 Varsity Medical Ethics debate convened upon the motion: “This house believes nootropic drugs should be available under prescription”. This annual debate between students from the Universities of Oxford and Cambridge, now in its seventh year, provided the starting point for arguments on the subject. The present article brings together and extends many of the arguments put forward during the debate. We explore the current usage of nootropic drugs, their safety and whether it would be beneficial to individuals and (...) society as a whole for them to be available under prescription. The Varsity Medical Debate was first held in 2008 with the aim of allowing students to engage in discussion about ethics and policy within healthcare. The event is held annually and it is hoped that this will allow future leaders to voice a perspective on the arguments behind topics that will feature heavily in future healthcare and science policy. This year the Oxford University Medical Society at the Oxford Union hosted the debate. (shrink)

Drawing on early work on ethical leadership, we argue that when leaders engage in leader moral hypocrisy (i.e., ethical promotion without ethical demonstration), followers can experience psychological reactance—a negative response to a perceived restriction of freedom—which can have negative downstream consequences. In a survey of employee–manager dyads (study 1), we demonstrate that leader moral hypocrisy is positively associated with follower psychological reactance, which increases follower deviance. In two subsequent laboratory experiments, we find similar patterns of results (study 2) and explore (...) potential alternative mechanisms (study 3). We demonstrate in a final experiment with working adults that the relationship between leader moral hypocrisy and psychological reactance is partly explained by increased perceptions of a leader’s use of power (study 4). We discuss the implications of our findings and advocate for further understanding of the risks associated with psychological reactance in response to leaders and other workplace situations.

In the age of the `return to the empirical' in which the theoretical disputes of an earlier era seem to have fallen silent, we seek to excavate the intellectual conditions for reviving theoretical debate, for it is upon this recovery that deeper understanding of the nature and purpose of empirical social science depends. We argue against the all too frequent turn to ontology, whereby critical realists have sought an epistemological guarantor of sociological validity. We seek, to the contrary, to crystallize (...) a culturally-based, hermeneutic account of a rational social science. Derived from disputes within the sociology of culture, on the one hand, and the long-standing concerns of interpretive philosophy, on the other, we offer a cultural-sociological approach to epistemology. We view the production of truth in social science as a reading of a meaningful social world, and as a performance of truth-claims that is constrained by evidence, but whose success depends on other contextual factors. We conclude that the rationality of social science can be achieved only by forgoing ontology. Theories are abstractions of investigators' meanings that allow the interpretation of social meanings in turn, whether those are actions, relations, or structures. Successful explanations are those that intertwine these meaning structures of investigators and actors in an effective way. (shrink)

A replicator is simply something that makes copies of itself. There are hypothetical replicators (e.g., self-catalyzing chemical cycles) that are suspected to be unable to exhibit heritable variation. Variation in any of their constituent molecules would not lead them to produce offspring with those new variant molecules. Copying, such as in DNA replication or in xerox machines, allows any sequence to be remade and then sequence variations to be inherited. This distinction has been used against non-RNA-world hypotheses: without RNA replication (...) systems have no capacity to exhibit heritable variation. However, is copying the only way to have heritable variation? This article suggests that evolution can happen without anything being copied and that, in fact, RNA copying is too complex to arise spontaneously as the first pre-biotic system. There would then be a historical gradation of systems from non-alive to alive in which the capacity to have heritable changes would progressively increase and in which copying, as in template-based RNA-replication, would be a crucial but relatively late event. In addition, this article proposes a way by which RNA replication could have arisen, after systems able to evolve arose, as a crucial innovation and how that innovation spread over existing evolutionary systems and became a major driver of subsequent evolution.

En oposición al escepticismo declarado por Callender y Cohen respecto de la existencia de algún problema en torno a la representación científica, el objetivo de este artículo es mostrar un conjunto de características peculiares de la representación científica, aunque no exclusivas, que una teoría satisfactoria debe explicar. Estas son: la predicación, la posibilidad de ser una representación incorrecta, el razonamiento subrogatorio y la independencia entre el contenido y la denotación. Además, se argumenta que una teoría satisfactoria de la representación debe (...) ofrecer una definición de sus medios representacionales, es decir, de lo que es un modelo científico. Finalmente, se propone que para dar cuenta de estas características basta responder la pregunta: ¿Cómo nos permiten los modelos científicos ganar información sobre el objeto representado? (shrink)

Récit de la rencontre à Port-Royal-des-Champs en janvier 1655 entre Lemaistre de Sacy, théologien janséniste, et Pascal, jeune philosophe et savant reconnu.

Científicos del sistema Tierra han demostrado que el planeta es un sistema adaptativo-complejo y que algunos procesos naturales ya no operan en condiciones seguras para preservar la vida. Destaca que poco se ha hecho por explorar las implicaciones en la arena jurídica para responder ante los retos que estas condiciones presuponen para la vida humana y para nuestra supervivencia como especie. Aquí se sostiene que, para mantener el buen funcionamiento planetario, se requiere de una articulación efectiva entre el razonamiento jurídico, (...) su argumentación y la ciencia del sistema Tierra. Al hacer una exploración de la literatura jurídica y del sistema Tierra, este artículo tiene como objetivo exponer el primer esfuerzo sobre cómo debería adaptarse el razonamiento jurídico y su argumentación a un enfoque del sistema Tierra, utilizando para ello diferentes casos de estudio, resoluciones y tesis jurisprudenciales. Al hacerlo, se exhibe la necesidad de erradicar concepciones erróneas subyacentes al antropocentrismo jurídico, para ajustar la interpretación y aplicación del derecho a realidades ecológicas científicamente más precisas.

This article will argue that the church is the mystic body of Christ that believers must guard from purveyors bend on twisting the truth. There is no doubt that the Catholic social teaching on medical and moral matters has proven to be pertinent and applicable to the ever-changing circumstances of health care and its delivery. In response to today’s challenges, these same moral principles of Catholic teaching provide the rationale and direction for the community of faith. In times of coronavirus (...) characterized by falsehoods, the truth is a virtue the church must strive for: “… If you abide in My word, you are My disciples indeed. And you shall know the truth, and the truth shall make you free.”(John 8: 31-32). The truth is Christ; it is Christological. Christians must understand the clash of worldviews that is changing the face of Zimbabwean society. A worldview is simply the sum total of our beliefs about the world; Christianity is a worldview that directs our daily decisions and actions. Worldviews affect the way we think. A worldview is a well-reasoned framework of beliefs and convictions that gives a true and unified perspective on the meaning of human existence. To paraphrase from the book of First Samuel (16: 7) – to see as God sees and not how the world sees. Beliefs are not simple propositions held inside us which drive our outward behaviour in predictable ways, they are more of acts of commitment than anything else. There is no doubt that the future of Catholicism lies in the hands of the church’s leadership and the believing Christians. Catholics look to their faith leaders for guidance on big decisions as regards COVID-19 issues. Conspiracy theories around COVID-19 deny that the COVID-19 pandemic is a biological virus. Catholics require direction from the Pope down to the episcopal leadership to chart the way forward. A worldview not only impacts how one understands and makes sense of the world but also influences how one expresses oneself in the world. The constellation of personal values, beliefs, assumptions, attitudes, and ideas that make up our worldview have an effect on our understanding of reality. Coronavirus has caused uncertainty among believers and confusion as to how to cope with the complex problems that arise in COVID-19 related issues. This article will aver that the nature of drawing the contours of catholicity regarding the biblical foundations of the health falls in the hands of orthodox Catholic teachings. (shrink)

Los Estados confederados proyectan la existencia de un doble sistema normativo: federal y local. Esto provoca el surgimiento de colisiones y contradicciones entre ambos sistemas, lo que se pensaría debería ser resuelto por el derecho internacional, atendiendo el principio de subsidiariedad, no obstante, esto no siempre es así, ya sea porque el derecho internacional no regule ese caso concreto o bien, porque el Estado en cuestión no haya otorgado su consentimiento y la respuesta no le sea vinculante. Estas reflexiones invitan (...) a contrastar la naturaleza de las normas del derecho local y del derecho internacional, pues mientras que las primeras son asociativas, dado que no necesariamente requieren ser consentidas para ser vinculantes, las segundas, aparentemente, sí requieren el consentimiento de los Estados para que tengan efectos vinculantes. En este artículo pretendemos postular una posible solución al problema del conflicto entre los distintos órdenes normativos, partiendo desde una postura cuasi-voluntarista. Las obligaciones cuasi-voluntarias son aquellas que no surgen del consentimiento, pero tampoco completamente de los roles que tienen los Estados en el sistema internacional. Estas obligaciones nacen en el núcleo de grupos dominantes, a los que llamaremos grupos autocontenidos en el ámbito internacional, que tienen como rol la creación y socialización de las normas y obligaciones de derecho internacional, logrando que los otros grupos simplemente las sigan como si tuvieran un deber de hacerlo. Para ello, servirá como referencia el análisis del caso de las disimiles normas migratorias entre California y Texas dentro de Estados Unidos. (shrink)

Research heuristics—implicit rules used to guide work on a scientific problem—are explored for their role in guiding psychological research. Work on the psychology of creativity is used to illustrate how heuristics have guided research. We examine the influence of three heuristics: the trilogy-of-mind heuristic, the emotions-as-moods heuristic, and the analysis-of-variance heuristic. This analysis of multiple heuristics provides a new way to understand the state of research on creativity. In the discussion, the analysis is extended to other heuristics and to how (...) heuristics may help as well as hinder innovative research. (shrink)
