In providing a good foundation for mathematics, set theorists often aim to develop the strongest theories possible and avoid those theories that place undue restrictions on the capacity to possess strength. For example, adding a measurable cardinal to $ZFC$ is thought to give a stronger theory than adding $V=L$ and the latter is thought to be more restrictive than the former. The two main proponents of this style of account are Penelope Maddy and John Steel. In this paper, I’ll offer (...) a third account that is intended to provide a simple analysis of restrictiveness based on the algebraic concept of retraction in the category of theories. I will also deliver some results and arguments that suggest some plausible alternative approaches to analyzing restrictiveness do not live up to their intuitive motivation. (shrink)

A fascinating recent turn in epistemology focuses on inquiring attitudes like wondering and being curious. Many have argued that these attitudes are governed by norms similar to those that govern our doxastic attitudes. Yet, to date, this work has only considered norms that might *prohibit* having certain inquiring attitudes (``norms of restriction''), while ignoring those that might *require* having them (``norms of expansion''). We aim to address that omission by offering a framework that generates norms of expansion for inquiring attitudes. (...) The framework draws on inferential erotetic logic, which we explain and augment with some theorems. We explore several of the norms that it yields - some sympathetically, others unsympathetically.

This paper extends several themes from recent work on norms of assertion. It does as much by applying those themes to the speech act of asking. In particular, it argues for the view that there is a species of asking which is governed by a certain norm, a norm to the effect that one should ask a question only if one doesn’t know its answer.

This paper explores the nature of curiosity from an epistemological point of view. First it motivates this exploration by explaining why epistemologists do and should care about what curiosity is. Then it surveys the relevant literature and develops a particular approach.

This book represents a considerable revision and expansion of Public Choice II. Six new chapters have been added, and several chapters from the previous edition have been extensively revised. The discussion of empirical work in public choice has been greatly expanded. As in the previous editions, all of the major topics of public choice are covered. These include: why the state exists, voting rules, federalism, the theory of clubs, two-party and multiparty electoral systems, rent seeking, bureaucracy, interest groups, dictatorship, the (...) size of government, voter participation, and political business cycles. Normative issues in public choice are also examined including a normative analysis of the simple majority rule, Bergson–Samuelson social welfare functions, the Arrow and Sen impossibility theorems, Rawls's social contract theory and the constitutional political economy of Buchanan and Tullock.

I discuss the relationship between different versions of the equivalence principle in general relativity, among them Einstein's equivalence principle, the weak equivalence principle, and the strong equivalence principle. I show that Einstein's version of the equivalence principle is intimately linked to his idea that in GR gravity and inertia are unified to a single field, quite like the electric and magnetic field had been unified in special relativistic electrodynamics. At the same time, what is now often called the strong equivalence (...) principle, related to the local validity of special relativity, can also be found in Einstein's writings, albeit by a different name and clearly separated from what he calls the equivalence principle. I discuss both the development of Einstein's thoughts on the different versions of the equivalence principle, their relationship to the relativity principle, as well as later reflections and variants proposed.

I have been trying to understand the moral aspect of human nature for several decades. Several years ago, after publishing The Origins of Morality, an editor from Oxford Press suggested that I write up the theory and research I reviewed in this academic book in a manner that would be accessible to people with relatively little background knowledge in the area. A few years later, I launched this project, which ended up in this book. In it, I trace the grown (...) of my understanding of morality. (shrink)

This contributed volume is the result of a July 2010 workshop at the University of Wuppertal Interdisciplinary Centre for Science and Technology Studies which brought together world-wide experts from physics, philosophy and history, in order to address a set of questions first posed in the 1950s: How do we compare spacetime theories? How do we judge, objectively, which is the “best” theory? Is there even a unique answer to this question? -/- The goal of the workshop, and of this book, (...) is to contribute to the development of a meta-theory of spacetime theories. Such a meta-theory would reveal insights about specific spacetime theories by distilling their essential similarities and differences, deliver a framework for a class of theories that could be helpful as a blueprint to build other meta-theories, and provide a higher-level viewpoint for judging which theory most accurately describes nature. But rather than drawing a map in broad strokes, the focus is on particularly rich regions in the “space of spacetime theories.” -/- This work will be of interest to physicists, as well as philosophers and historians of science working with or interested in General Relativity and/or Space, Time and Gravitation more generally.

Does a flourishing life involve pursuing passionate attachments? Can we choose what these passionate attachments will be? This book offers an original theory of how we can actively cultivate our passionate attachments. The author argues that not only do we have reason to view passionate attachments as susceptible to growth, change, and improvement, but we should view these entities as amenable to self-cultivation. He uses Pierre Hadot's and Michel Foucault's accounts of Hellenistic self-cultivation as vital conceptual tools to formulate a (...) theory of cultivating our passionate attachments. First, their accounts offer the conceptual resources for a philosophical theory of how we can cultivate our passionate attachments. Second, the exercises of self-cultivation they focus on allow us to outline a practical method though which we can cultivate our passionate character. Doing this brings out a significantly new dimension to the role of the passionate attachments in the flourishing life and offers theoretical and practical accounts of how we can cultivate them based on the Hellenistic conception of self-directed character change. Cultivating Our Passionate Attachments will be of interest to advanced students and scholars working in virtue ethics, moral philosophy, and ancient philosophy. (shrink)

How does sign language compare with gesture, on the one hand, and spoken language on the other? Sign was once viewed as nothing more than a system of pictorial gestures without linguistic structure. More recently, researchers have argued that sign is no different from spoken language, with all of the same linguistic structures. The pendulum is currently swinging back toward the view that sign is gestural, or at least has gestural components. The goal of this review is to elucidate the (...) relationships among sign language, gesture, and spoken language. We do so by taking a close look not only at how sign has been studied over the past 50 years, but also at how the spontaneous gestures that accompany speech have been studied. We conclude that signers gesture just as speakers do. Both produce imagistic gestures along with more categorical signs or words. Because at present it is difficult to tell where sign stops and gesture begins, we suggest that sign should not be compared with speech alone but should be compared with speech-plus-gesture. Although it might be easier to blur the distinction between sign and gesture, we argue that distinguishing between sign and gesture is essential to predict certain types of learning and allows us to understand the conditions under which gesture takes on properties of sign, and speech takes on properties of gesture. We end by calling for new technology that may help us better calibrate the borders between sign and gesture. (shrink)

This paper reconstructs Steel’s multiverse project in his ‘Gödel’s program’ (Steel [2014]), first by comparing it to those of Hamkins [2012] and Woodin [2011], then by detailed analysis what’s presented in Steel’s brief text. In particular, we reconstruct his notion of a ‘natural’ theory, describe his multiverse axioms and his translation function, and assess the resulting status of the Continuum Hypothesis. In the end, we reconceptualize the defect that Steel thinks CH might suffer from and isolate what it would take (...) to remove it while working within his framework. As our goal is to present as coherent and compelling a philosophical and mathematical story as we can, we allow ourselves to augment Steel’s story in places (e.g., in the treatment of Amalgamation) and to depart from it in others (e.g., the removal of ‘meaning’ from the account). The relevant mathematics is laid out in the appendices. (shrink)

The position that I seek to defend in this article is that the epistemological hegemony that is presently one of the defining characters of the relationship between Africa and the global North is a form of injustice which makes the talk of ‘global justice’ illusory. In arguing thus, I submit that denying the indigenous people of Africa an epistemology that is comparable to epistemologies from other geopolitical centres translates to questioning their humanity which is a form of injustice. I thus (...) proceed to argue that, as a precondition to an authentic discourse on the possibility of ‘global justice’; epistemic injustice must first be challenged and rejected. In so doing, I am defending the position that the acceptance and respect for the diversity of the peoples of this world and their epistemologies is imperative if genuine justice at global level is to be realised.

Is it possible that all of the social sciences could employ a common methodology? If so, what would it be? This article adresses these questions. It takes off from James Coleman’s recent book, The Foundations of Social Theory. Coleman’s social theory is built on the postulate that individuals are rational actors, the same postulate that most of modern economics is built upon. This article critiques the use of this postulate in economics, and thus questions whether it is a useful building (...) block for the methodological foundations of social science research. It proposes an adaptive view of human behavior as an alternative in which preferences are conditioned by past experience. The work of Joseph Schumpeter is discussed as an exemplar of the methodology advocated here. (shrink)

The surprising aspects of quantum information are due to two distinctly non-classical features of the quantum world: first, different quantum states need not be orthogonal and, second, quantum states may be entangled. Non-orthogonality leads to the blurring of classical distinctions. On the other hand, entanglement leads via non-locality to teleportation and other ``entanglement-assisted'' forms of communication that go beyond what is classically possible. In this article we attempt to understand these new possibilities via an analysis of the significance of entanglement (...) for the basic physical concepts of a ``particle'' and a ``localized physical system''. Classical particles can be individuated on the basis of qualitative differences in their sets of properties. But in entangled states the ``particle labels'' of the quantum formalism usually do not pick out such sets of individuating particle properties. It is sometimes nevertheless possible to think in terms of individual particles, which may be localized; but we argue that in general the structure of quantum mechanics is at odds with such a particle interpretation. This finally leads us to the conclusion that quantum mechanics is best seen as not belonging to the category of space-time theories, in which physical quantities are functions on space-time points. The resulting picture of the quantum world is relevant for our understanding of the way in which quantum theory is non-local, and it sheds light on the novel aspects of quantum information. (shrink)

A hallmark of Western culture is a massive moral confusion, rendering the very idea of virtue "exotic and incomprehensible." McInerny here drags the conversation back to the beginning, establishing the terms and the tools of what it means to think and to do what is moral. As he asserts, the virtuous life and the moral life are one and the same. To be moral is to be good, and the goodness of one's acts reflects the fundamentals of thought placed in (...) the service of a pursuit of a virtuous life. Why is the concept of a virtuous life so foreign to many? We do not know the basics of a moral life. As McInerny states, "To be good we have to know what that means." The two biggest judgments one will make during life pertain to knowing what is good, what is bad, and the difference between the two. This bleeds into a study of morality and ethics when it pertains to concrete acts, but in reality all aspects of our lives bear on these judgments. "Being ethical is not simply a state of mind, it is a state of being, a way of living one's life that reflects the fundamental principles of ethics [...] [it is one] who lives in a certain way." Nevertheless, the subject of this book focuses on ethics--namely, the goodness or badness of human acts. McInerny's great reason for writing this work is to teach the reader that he or she cannot properly tackle ethical questions (even if they are not identified as such) if one is not himself or herself actually ethical (living virtuously). Writing very much as a teacher of teachers, McInerny relies on the foundations of Aristotle and Thomas Aquinas, as well as his late brother, Ralph McInerny, to reiterate the principles of ethics that inform both thought and act. To speak of ethics, then, is to admit a commitment to virtue and how the theoretical distinction of good and bad is necessarily practical. Acting well will lead to thinking better, but McInerny notes that culture has lost sight of the former and thereby the coherency to address ethical questions. Being Ethical aims to correct this disconnect in forty-eight cogent lessons. Being Ethical is fundamentally intended to serve as a sequel to D. Q. McInerny's Being Logical (Random House, 2004), which has remained in print and has been translated into six languages. Its style lends itself to being used as a textbook in liberal studies. More generally, it is a refreshing presentation of this topic and timely and timeless exhortation to readers of the necessity of a love of virtue for ethical thought. For friends and students of Aristotle, Thomas Aquinas and Ralph McInerny, this book bears a style and manner that is both familiar and much loved. (shrink)

On Dwelling explores the meaning of dwelling in places where we humans live and work—from our homes to the very planet we co-inhabit. Crossing boundaries and disciplines, it lays the groundwork for addressing place-based issues like migration, ethnic division, resource use, and human-caused peril to the earth itself.

The central task of this dissertation is to develop a new interpretation of Leibniz's famous claim that there are no purely extrinsic denominations . Though Leibniz regarded NPE as one of his most important doctrines, he nowhere offers an explicit statement as to what he meant by it. One interpretation of NPE, which enjoys a modest consensus among interpreters, is that all extrinsic denominations reduce to intrinsic denominations. According to the reductionist view, things only have intrinsic denominations as properties; extrinsic (...) denominations are not genuine properties of things. Critics of reductionism have argued that the textual case for it is inconclusive at best, and I share this assessment with them. However, in my opinion, a satisfactory non-reductionist understanding of NPE has not been offered. The goal of my dissertation is to provide such a non-reductionist account. I contend that NPE, far from being a claim of the reducibility of extrinsic denominations, is actually an assertion that extrinsic denominations are genuine properties of the things they denominate. ;To establish my reading of NPE, I examine a line of textual evidence to which interpreters have paid little attention: the way Leibniz argues for NPE. In some passages Leibniz derives NPE from his predicate-in-subject principle of truth. In others, he employs his doctrine of the interconnection of all things to reach NPE. Elsewhere, he bases NPE on the principle of the identity of indiscernibles. Though, as mentioned, Leibniz never explicitly defines NPE, he does have much to say by way of explicit definition of each of these three principles. A consideration of what version of NPE could plausibly be drawn from them is thus a revealing way to proceed. In the case of each argument, I show that my interpretation of NPE is the conclusion naturally suggested by the given principle, while the reductionist version of NPE forms only an awkward, textually implausible fit with it. The result of the examination is an original and serious critique of the reductionist reading of NPE, as well as the development of a far more plausible understanding of that claim. (shrink)

Einst galt die Erkenntnistheorie als Königsdisziplin der Philosophie. Heute ist sie gegenüber der Ontologie und Sprachphilosophie in den Hintergrund getreten. Wenn wir aber das Programm der Aufklärung fortführen und in einer rationalen Gesellschaft leben wollen, müssen wir die Epistemologie wiederbeleben. In diesem Buch werden zwei Kernfragen der Disziplin beleuchtet. Alle Wissenschaften setzen auf Schlüsse vom Speziellen auf das Allgemeine, von der Vergangenheit auf die Zukunft. Der erste Teil des Buches beschäftigt sich damit, wie solche Induktionsschlüsse gerechtfertigt werden können. Im zweiten (...) Teil geht um das Problem der empirischen Basis. Viele PhilosophInnen glauben, dass selbst die grundlegendsten empirischen Beobachtungen durch unsere theoretischen Hintergrundannahmen geprägt sind. Sind Wissenschaft und Erkenntnis also zirkuläre Unterfangen? (shrink)

All languages, both spoken and signed, make a formal distinction between two types of terms in a proposition – terms that identify what is to be talked about (nominals) and terms that say something about this topic (predicates). Here we explore conditions that could lead to this property by charting its development in a newly emerging language – Nicaraguan Sign Language (NSL). We examine how handshape is used in nominals vs. predicates in three Nicaraguan groups: (1) homesigners who are not (...) part of the Deaf com- munity and use their own gestures, called homesigns, to communicate; (2) NSL cohort 1 signers who fashioned the first stage of NSL; (3) NSL cohort 2 signers who learned NSL from cohort 1. We compare these three groups to a fourth: (4) native signers of American Sign Language (ASL), an established sign language. We focus on handshape in predicates that are part of a productive classifier system in ASL; handshape in these predicates varies sys- tematically across agent vs. no-agent contexts, unlike handshape in the nominals we study, which does not vary across these contexts. We found that all four groups, including home- signers, used handshape differently in nominals vs. predicates – they displayed variability in handshape form across agent vs. no-agent contexts in predicates, but not in nominals. Variability thus differed in predicates and nominals: (1) In predicates, the variability across grammatical contexts (agent vs. no-agent) was systematic in all four groups, suggesting that handshape functioned as a productive morphological marker on predicate signs, even in homesign. This grammatical use of handshape can thus appear in the earliest stages of an emerging language. (2) In nominals, there was no variability across grammatical con- texts (agent vs. no-agent), but there was variability within- and across-individuals in the handshape used in the nominal for a particular object. This variability was striking in homesigners (an individual homesigner did not necessarily use the same handshape in every nominal he produced for a particular object), but decreased in the first cohort of NSL and remained relatively constant in the second cohort. Stability in the lexical use of handshape in nominals thus does not seem to emerge unless there is pressure from a peer linguistic community. Taken together, our findings argue that a community of users is essential to arrive at a stable nominal lexicon, but not to establish a productive morpholog- ical marker in predicates. Examining the steps a manual communication system takes as it moves toward becoming a fully-fledged language offers a unique window onto factors that have made human language what it is. (shrink)

In its attempt to prove that voters, politicians, and bureaucrats are motivated by the public interest, Self-Interest and Public Interest in Western Politics overlooks a great deal of public-choice research, to which much has been added during the two decades since it was published. The importance of self-interest at both the micro and macro levels of politics becomes clear once one looks not simply at the “inputs” of a democracy but at its “outputs” as well. The prevalence of interest groups, (...) the dysfunction of the United States tax code, the lobbying by unions for their members’ self-interest, the earmarks in the Patriot Act, the numerous cases of corruption in Western democracies, and the dissatisfaction of citizens with their governments’ failings all point to the importance of self-interest in politics.

RESUMO Este artigo analisa a atuação das forças centrípetas e centrífugas em enunciados da esfera religiosa que evidenciam cosmovisões do segmento cristão evangélico acerca da deficiência. Para tanto, selecionamos um vídeo disponível na plataforma YouTube contendo enunciados dos apresentadores Tito Rocha e Leandro Quadros relativos à temática da deficiência, bem como a resposta de uma internauta acerca do posicionamento desses sujeitos. A reflexão teórico-metodológica fundamenta-se na orientação dialógica da linguagem, sobretudo nas considerações acerca das relações dialógicas, vozes e forças centrípetas (...) e centrífugas. Também recorremos a estudos sobre cosmovisão, inclusão da pessoa com deficiência, discurso religioso e teologia cristã. Os resultados indicam que os discursos dos apresentadores refletem e refratam uma cosmovisão cristã que unifica o entendimento da deficiência como resultado da condenação divina ocasionada pelo pecado. O comentário da internauta, por sua vez, apresenta movimentos de centralização e dispersão dessa perspectiva cristã. (shrink)

ABSTRACT This article analyzes the action of centripetal and centrifugal forces in utterances from the religious sphere, which reveal worldviews of the evangelical Christian segment regarding disability. For that, we selected a video available on YouTube, containing utterances by the hosts Tito Rocha and Leandro Quadros regarding disabilities, as well as the response of an internet user about the positioning of these individuals. The theoretical and methodological reflection is based on the dialogical orientation of language, considering dialogic relations, voices, and (...) centripetal and centrifugal forces. Additionally, we drew upon studies on worldviews, the inclusion of people with disabilities, religious discourse, and Christian theology. The results reveal that the discourses of the hosts reflect and refract a Christian worldview that unifies the understanding of disability due to divine punishment caused by sin. While the internet user’s comment presents movements of centralization and dispersion of this Christian perspective. (shrink)

Kann "Gott" Thema einer vernunftigen, undogmatischen Philosophie sein? Wenn ja, in welcher Weise? Uber eine systematische Rekonstruktion des philosophischen Werkes von Simon L. Frank (1877-1950) werden diese Fragen erortert. Der erkenntnismetaphysische Grundansatz Franks vereinigt Transzendentalphilosophie und Phanomenologie. Er fuhrt zu einer "Fundamentalontologie", die durch ihre immanente Verbindung zur Anthropologie wesentlich personale Ontologie ist. Der Uberschritt zur philosophischen Theologie wird anhand des Begriffes "religioser Erfahrung" herausgearbeitet. Wissenschaftlichkeit sowie philosophische und religiose Adaquatheit dieses Unterfangens werden uberpruft. Dabei wird sowohl dem Verdacht auf (...) "Ontotheologie" als auch dem Vorwurf des "Pantheismus" kritisch nachgegangen. (shrink)

Recent decades have seen a revived interest in super-substantivalism, the idea that spacetime is the only fundamental substance and matter some kind of aspect, property or consequence of spacetime structure. However, the metaphysical debate so far has misidentified a particular variant of super-substantivalism with the position per se. I distinguish between a super-substantival core commitment and different ways of fleshing it out. I then investigate how general relativity and alternative spacetime theories square with the different variants of super-substantivalism.
