First-ever comprehensive introduction to the major new subject of quantum computing and quantum information.

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)

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.

In this paper, I investigate the foundations of Plotinus’ innovative theory that prime matter is unaffectable. I begin by showing that Plotinus’ main arguments for this thesis (in Ennead 3.6) all rely upon the controversial assumption that the properties prime matter underlies are not properties of prime matter itself. It is then argued that prime matter’s privation of sensible qualities has its conceptual basis in an idiosyncratic understanding of form-matter composition generally, and its primary doctrinal basis in Aristotle’s critical reports (...) on the Platonists’ substratum in Physics 1.9. While Plotinus finds Platonic authority for unaffectible matter in the Receptacle passage of the Timaeus, it is Aristotle’s testimony that provides the crucial impetus for reading that text in this way. On this basis, Plotinus develops a Platonist conception of form’s inherence in matter with distinctively non-Aristotelian features. (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.

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.‎.

Schopenhauer repeatedly claims that all pleasure is negative, and this view seems to play key roles throughout his work. Nonetheless, many scholars have argued that Schopenhauer actually acknowledges certain positive pleasures. Two major arguments have been offered for this reading, one focused on the link between Schopenhauer's view of pleasure and Plato's, and one focused on Schopenhauer's distinction between two components of aesthetic pleasure. I argue that neither way of motivating the positive pleasure reading succeeds. Both overlook a key aspect (...) of Schopenhauer's account: namely, his suggestion that there are two distinct kinds of negative pleasure, pleasures of satisfaction and pleasures of distraction. When Schopenhauer claims that all pleasure is negative, he means it. (shrink)

Ectogenesis, or “artificial womb technology,” has been heralded by some, such as prominent feminist Shulamith Firestone, as a way to liberate women. In this chapter, we challenge this view by offering an alternative analysis of the technology as relying upon and perpetuating a problematic model of pregnancy which, rather than liberating women, serves to devalue them. We look to metaphysics as the abstract study of reality to elucidate how the entities in a pregnancy are related to one another. We consider (...) two models of the metaphysics of pregnancy: (1) the Parthood Model, whereby the fetus is a part of what/who gestates it; and (2) and the Fetal Container Model, whereby the gestator is a container for the fetus. We suggest that under the assumption of the Fetal Container Model, we are more likely to think that any container will suffice for gestation, even an artificial one. In contrast, under the assumption of the Parthood Model, we are less likely to treat the gestator as interchangeable or replaceable, given the parthood relationship between gestator and fetus. This chapter argues that ectogenesis is conceptually linked to the Fetal Container Model and advocates a more cautious approach in promoting ectogenesis as a tool for women’s liberation. (shrink)

Mill defines utilitarianism as the combination of a “theory of life” and a moral claim: only pleasure and freedom from pain are desirable as ends, and the promotion of happiness is the sole goal of moral action. So defined, utilitarianism is open to ad hominem pessimistic objection: a “theory of life” which entails the impossibility of happiness fits poorly with a morality centered on its promotion. The first two challenges Mill confronts in Utilitarianism share this pessimistic structure. Interestingly, however, these (...) challenges paint inverted pictures of the best utilitarian life: one suggests this life is satisfying but ignoble, the other that it is noble but unsatisfying. I explain Mill's treatment of both challenges as genuinely pessimistic interpretations of utilitarianism's “theory of life.” Read through the lens of Mill's engagement with pessimism, these challenges point to distinctive conceptions of dignity and satisfaction that play a significant role in Mill's ethics.

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.

Plotinus maintains that there is a single first principle, the One (or the Good), from which all other things derive. He is usually thought to hold this view on the grounds that any other thing’s existence depends on its participation in a paradigm of unity. This paper argues that Plotinus has a further, independent argument for adopting a single first principle, according to which principle pluralism is committed (unacceptably) to attributing good cosmic states of affairs to chance. This argument exhibits (...) similarities to ancient design arguments, but is used to draw the more radical conclusion that there is only one non-derivative existent. (shrink)

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)

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.

As part of a project on professionals' lived experience of ethics, this article explores the guiding concepts and values concerning ethics of mental health professionals in Cuba. The data, obtained through individual interviews and focus groups with 28 professionals, indicate that Cubans conceptualize applied ethics in terms of its central role in professional practice and its connection to the social context and subjective processes. Findings also show that Cuban professionals are guided not only by a set of professional values but (...) by a specific set of civic values as well. The former are subdivided into other-oriented values and self-oriented values. The study of ethics in another culture such as Cuba offers a unique point of view from which to critique the social construction of our own conceptions of applied ethics in North America. (shrink)

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)

Traces the decentered formulation of self at the heart of Paul Ricoeur's philosophy from his earliest works to his most recent.

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.

Antimicrobial resistance (AMR) is an urgent threat to global public health and development. Mitigating this threat requires substantial short-term action on key AMR priorities. While international legal agreements are the strongest mechanism for ensuring collaboration among countries, negotiating new international agreements can be a slow process. In the second article in this special issue, we consider whether harnessing existing international legal agreements offers an opportunity to increase collective action on AMR goals in the short-term. We highlight ten AMR priorities and (...) several strategies for achieving these goals using existing “legal hooks” that draw on elements of international environmental, trade and health laws governing related matters that could be used as they exist or revised to include AMR. We also consider the institutional mandates of international authorities to highlight areas where additional steps could be taken on AMR without constitutional changes. Overall, we identify 37 possible mechanisms to strengthen AMR governance using the International Health Regulations, the Agreement on the Application of Sanitary and Phytosanitary Measures, the Agreement on Trade-Related Aspects of Intellectual Property Rights, the Agreement on Technical Barriers to Trade, the International Convention on the Harmonized Commodity Description and Coding System, and the Basel, Rotterdam, and Stockholm conventions. Although we identify many shorter-term opportunities for addressing AMR using existing legal hooks, none of these options are capable of comprehensively addressing all global governance challenges related to AMR, such that they should be pursued simultaneously with longer-term approaches including a dedicated international legal agreement on AMR.

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)

The paper examines some doctrines of the Davidsonian Programme of truth conditional Semantics that relates truth to meaning using Tarski’s T-Convention, in relation to its efficacy in a semantic valuation of the EkeGusii proverb: Nda ’indongi ereta morogi ereta moibi which exemplifies a kind of complex sentence that a given system of Semantics is meant to account for. The coverage of Davidsonian truth-conditional notion of T-convention and that of compositionality are considered to have only a partial reach in accounting for (...) the meaning of the proverb by not incorporating pragmatic aspects. The failure of T-convention is not alleviated by the adoption of radical interpretation as posited by Davidson but is extended to consider aspects of pragmatic enrichment and dynamic Semantics.

The issue contains contributions by James Andow, Delia Belleri, David Chalmers, Catarina Dutilh Novaes, Eugen Fischer, Viktoria Knoll, Edouard Machery and Amie Thomasson. We, the editors, provide a brief introduction to the main topics of the issue and then summarize its contributions.

The randomization of a complete first-order theory [Formula: see text] is the complete continuous theory [Formula: see text] with two sorts, a sort for random elements of models of [Formula: see text] and a sort for events in an underlying atomless probability space. We study independence relations and related ternary relations on the randomization of [Formula: see text]. We show that if [Formula: see text] has the exchange property and [Formula: see text], then [Formula: see text] has a strict independence (...) relation in the home sort, and hence is real rosy. In particular, if [Formula: see text] is o-minimal, then [Formula: see text] is real rosy. (shrink)

There is an important class of conditionals whose assertibility conditions are not given by the Ramsey test but by an inductive extension of that test. Such inductive Ramsey conditionals fail to satisfy some of the core properties of plain conditionals. Associated principles of nonmonotonic inference should not be assumed to hold generally if interpretations in terms of induction or appeals to total evidence are not to be ruled out.

We should disassociate ourselves from wrongdoing. If Hobby Lobby is against LGBTQ rights, we shouldn’t shop there. If Old Navy sources their clothing from sweatshops, we shouldn’t buy them. If animals are treated terribly in factory farms, we shouldn’t eat the meat, eggs, and dairy products that come from them. Let’s call these disassociation intuitions. What explains the existence and force of disassociation intuitions? And based on that explanation, are they intuitions worth taking seriously? In other words, depending on the (...) etiology of these intuitions, should we accept that you ought to dissociate yourself from wrongdoing? Our aim here is to outline a hypothesis that would, if true, answer the first question, and which suggests a way to vindicate some disassociation intuitions as morally correct. (shrink)

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)

We consider the complexity (in terms of the arithmetical hierarchy) of the various quantifier levels of the diagram of a computably presented metric structure. As the truth value of a sentence of continuous logic may be any real in [0, 1], we introduce two kinds of diagrams at each level: the closed diagram, which encapsulates weak inequalities of the form $$\phi ^\mathcal {M}\le r$$, and the open diagram, which encapsulates strict inequalities of the form $$\phi ^\mathcal {M}< r$$. We show (...) that the closed and open $$\Sigma _N$$ diagrams are $$\Pi ^0_{N+1}$$ and $$\Sigma ^0_N$$ respectively, and that the closed and open $$\Pi _N$$ diagrams are $$\Pi ^0_N$$ and $$\Sigma ^0_{N + 1}$$ respectively. We then introduce effective infinitary formulas of continuous logic and extend our results to the hyperarithmetical hierarchy. Finally, we demonstrate that our results are optimal. (shrink)

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)
