The five books of Artemidorus of Ephesus’ Oneirocritica (c. second century CE) constitute the largest collection of divinatory dream-interpretations to survive from Graeco-Roman antiquity. This article examines Artemidorus’ contribution to longstanding medico-philosophical debates over the ontological and epistemic character of such dreams. As with wider Mediterranean traditions concerning premonitory dreams, Greeks and Romans popularly understood them as phenomena with origins exterior to the dreamer (e.g. a visitation of a god). Presocratic and Hippocratic thinkers, however, initiated an effort to bring at (...) least some dream events within the body as interior processes of a physical soul, a bodily turn which ultimately engendered a split in thinking about the possibility and scope of prophetic and diagnostic dreams (e.g. Hippocrates Regimen 4, Aristotle On Prophecy in Dreams, Rufus of Ephesus, and Galen). Here, I examine the way that Artemidorus meant the Oneirocritica to address seriously questions about the origins of dreams and the powers of empirical science in two, related ways. We will see that his defense of oneirocriticism as a techne unfolds along two main axes. First, Artemidorus constructs a necessary veneer of scientific credibility by mobilizing the tropes and organizational strategies characteristic of contemporary technical literature. Secondly, he anchors that authority upon a materialist account of prophetic dreams as “semiotic movements of the soul.” As Price, S. 1986. “The Future of Dreams: From Freud to Artemidorus.” Past & Present 113: 3–36 and Harris-McCoy, D. 2012. Artemidorus’ Oneirocritica: Text, Translation, and Commentary. Oxford: Oxford University Press observed, this explicit commitment to an empirical method of dream-interpretation resembles that of the Hellenistic medical ‘sect’ known as ‘Empiricists,’ who eschewed interest in theoretical etiology in favor of observation, comparison, and compilation of symptoms and outcomes. Pushing beyond similarity, I argue that Artemidorus not only deployed this method to defend empirically grounded accounts of dream-divination (cf. Cicero De div. 1), but endeavored to show that such a scientific method can be used to stabilize and corral productively the potentially infinite number of interpretations any dream-sign might bear without recourse to an underlying, causal theory.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.4 (2004) 489-490 [Access article in PDF] Ian M. Crystal. Self-Intellection and its Epistemological Origins in Ancient Greek Thought. Aldershot, England: Ashgate Publishing, 2002. Pp. x + 220. Cloth, $79.95. In this excellent re-working of his King's College Ph.D. thesis, Ian Crystal presents an account of the problem of self-intellection in Greek philosophy from Parmenides through Plotinus. The problem, at least as it (...) appears in ancient Greek philosophy, is connected to the way in which a faculty of soul relates to its proper object. For example, the proper object of the visual faculty is light, that of the auditory faculty sound, and it is the difference in kind between these proper objects that requires different faculties of soul in any account of how it is that we come to grasp the two different kinds of sensory data. Reason is itself a faculty of soul that is supposed to correspond to objects of cognition, but since it is possible to grasp, cognitively, the structure of this faculty the question arises: May this faculty function as its own object? The question is famously answered in the affirmative in Aristotle's treatise De anima at 430a2-5 on the grounds that any immaterial object of cognition is identical to thought itself (epi men gar tôn aneu hulês to auto esti to nooun kai to nooumenon).While this may seem like a peculiarly Aristotelian analysis of cognition (relying, as it does, on Aristotle's distinction between matter and form and his rather cryptic claim that the faculties of soul are actually what their proper objects are potentially), Crystal traces the idea both backwards and forwards in time, rooting the problem in Parmenides' general account of faculties of soul and tracing it through Plotinus's sophisticated account of noetic intellect, with visits along the way not only with Aristotle but Plato and the Stoics as well.The book is divided into three parts. In the first ("The Epistemological Origins") Crystal examines the evolution of the philosophical analysis of cognition from Parmenides through Plato. Parmenides, on this account, was the first to offer anything like a philosophical treatment of intellect (Greek nous). In particular, Parmenides distinguishes between a faculty of intellection and an object of that faculty. Plato, consciously working in the Parmenidean tradition, further analyses mind into its faculties and their proper objects but also gives a more detailed analysis of the epistemological subject. Specifically, Plato's treatment of the faculty in the Theaetetus provides an account of the structure of our cognitive faculty and how that structure relates to the metaphysics of the external world. It is here that Crystal recognizes the emergence of a linguistic component in the epistemic subject's cognitive activity (101; cf. Theaetetus189e6-190a6).Part II ("The Emergence of Self-Intellection") consists of a single chapter in which Crystal reads Aristotle's treatment of self-intellection in the De anima as "Aristotle's epistemological response to Plato." Since self-intellection per se really only emerges for the first time in the De anima, this chapter is in some sense the meatiest part of the book. We are given first a careful treatment of Aristotle's account of perception in DA3.2, affection in DA2.5 and De generatione et corruptione1.7, and the central problem of self-consciousness in DA3.2. The argument moves quickly here but Crystal's analysis is precise and clear. Next comes the analysis of the cognitive structure of intellect itself in DA3.4 and Crystal's account of how Aristotle's two aporiai (How can intellect be both a passive affection and something simple and impassive; and Is intellect itself an intelligible object) are responses to Plato's account of cognition at Theaetetus197c1-200d4 (the Aviary passage) on the one hand and to the general lack of an account of intelligible objects in the Theaetetus on the [End Page 489] other. On Crystal's account, Aristotle improves on Plato in the sense... (shrink)

The authors of this collection fail to make clear the distinction between naturalistic and purely logical/methodological approaches to the philosophy of science. I also criticise Thomas Nickles's attempt to devise an explanatory method for discovery in science using programs that produce trial and error explorations of a domain, which he thinks replaces the need for a conjecture a refutation approach (cf. Popper and Campbell). Such programs embody undeclared conjectures in the way they are set up.

Historically, philosophers of biology have tended to sidestep the problem of development by focusing primarily on evolutionary biology and, more recently, on molecular biology and genetics. Quite often too, development has been misunderstood as simply, or even primarily, a matter of gene activation and regulation. Nowadays a growing number of philosophers of science are focusing their analyses on the complexities of development, and in Embryology, Epigenesis and Evolution Jason Scott Robert explores the nature of development against current trends in (...) biological theory and practice and looks at the interrelations between development and evolution, an area of resurgent biological interest. Clearly written, this book should be of interest to students and professionals in the philosophy of science and the philosophy of biology. (shrink)

I talked to my chair for hours, without it responding—and then I heard its voice, its desire, its rhetoric: sit in me.A new specter of materialist thought, conveniently cloaked in "realism," now haunts philosophy and rhetoric—object-oriented ontology and object-oriented rhetoric.1 Ostensibly, OOO arrives as the logical next step for theories of anti-, extra-, and post-humanism that have, over the past several decades, sought to destabilize the privileged position of human exceptionalism....

Este trabalho apresenta uma discussão que tem como objetivo principal propor um novo risco ao contorno da noção de intericonicidade que aparece em Courtine, precisamente, em 2003. Aí encontramos uma abertura que nos permite traçar outras curvaturas em sua noção. É justamente por este interstício que vamos propor a inclusão de dois elementos que, a nosso ver, estão na ordem da constituição das imagens: as utopias e heterotopias, conforme discussões iniciadas anteriormente por Araújo (2014a, 2014b). Para tanto, tomamos como pano (...) de fundo as imagens em movimento de duas produções francesas de horror e as imagens fotográficas da prisão de Abou Ghraib que serão analisadas à luz da discussão realizada por Foucault em Le corps utopique, les heterotopies e em Outros Espaços, juntamente com as discussões de Courtine e de Milanez acerca da intericonicidade (cf. COURTINE, 2005; 2011; 2013; MILANEZ, 2011a; 2011b; 2013a, 2013b). Os Elementos de Semiologia e A escrita do acontecimento de Barthes também fazem parte da discussão, já que este autor aparece desde cedo no trabalho de Courtine, precisamente, quando buscava apresentar a noção de intericonicidade.

According to St. Thomas, the natures of material things are the proper objects of human understanding.Thomas claims only that the natures of things are the proper objects of the intellect, not that they are its only objects: he does not deny that we have intellective cognition also of the contingent states and situations of particular material things. And he holds that, at least in this life, humans cognize these natures, not through innate species or by perceiving the divine exemplars, but (...) only by abstraction from phantasms (ST Ia, 84.7, 85.1).This claim applies to the exercising of concepts already acquired, as well as their initial acquisition (ST Ia 84.7). Here and throughout, I use “cognition” to translate “cognitio.” As Scott MacDonald (“Theory of Knowledge” in Cambridge Companion to Aquinas, ed., N. Kretzmann and E. Stump [Cambridge: Cambridge University Press, 1993], p. 162) points out, translating “cognitio” with “knowledge” is misleading, given that cognitiones can, on Thomas’s account, be false (see, for example, ST Ia 17.3). I discuss Aquinas’s conception of cognition in section I.1. More precisely, the human intellect’s active component, the agent intellect, produces cognition of the natures of material things by abstracting intelligible forms from phantasms and informing them on its passive component, the possible intellect, to actualize the latter’s potency to understand.This division of the intellect into an active and a passive component originates in Aristotle’s cryptic remark that in the soul “there is a mind for becoming all things” and “a mind for producing all things” (DA III 5, 430a10). This passage has been subject to myriad interpretations. Aristotle’s Arabic commentators read him as saying that (one or both) of these intellects are single and separate from individual human souls. In opposition to these interpretations, Aquinas holds that the agent and possible intellects are both immanent powers of each individual soul. Since these interpretations enjoyed considerable popularity in Aquinas’s day, we often find him developing his account of the human intellect in explicit opposition to them (cf. OUIAA). The aim of the present piece is to clarify Thomas’s account of this intellective abstraction, and thereby the precise force of the conceptual empiricism it asserts.Important recent work by several scholars has advanced our understanding of many central aspects of Aquinas’s philosophy of mind and epistemology, including his account of intellective abstraction. See Eleonore Stump, “Aquinas on the Foundations of Knowledge,” Canadian Journal of Philosophy (Supplementary Volume) 17 (1992); “Aquinas’s Account of the Mechanisms of Intellective Cognition,” Revenue Internationale de Philosophie 52 (1998): 287–307; “Aquinas on Sensory Cognition,” in Medieval Analyses in Language and Cognition, eds. Sten Ebbesen and Russell L. Friedman, volume 77 in the series Det Kongelige Danske Videnskabernes Selskab, Historisk-Filosofiske Meddelelser (Copenhagen: Munksgaard, 1999), pp. 377–395. Norman Kretzmann, “Infallibility, Error, and Ignorance,” Canadian Journal of Philosophy 17 (1992); Kretzmann, “Philosophy of Mind,” in Cambridge Companion to Aquinas; Robert Pasnau, Theories of Cognition in the Later Middle Ages (Cambridge: Cambridge University Press, 1997); and Scott MacDonald (“Theory of Knowledge,” in Cambridge Companion to Aquinas).Many of these discussions share a salutary focus on Aquinas’s claims regarding the reliability of our faculties, so that their treatments of intellective abstraction tend to center on his prima faciae wildly implausible claim to its infallibility: “The proper object of intellect is the quiddity of a thing, and this is why intellect is not fallible regarding the quiddity of a thing, speaking of it just as such” (ST Ia 85.6). Kretzmann provides an interesting and detailed treatment of this claim. Drawing on a range of texts, he argues that the intellect’s apprehension of the quiddity of a thing is such that one acquires an initial, crude concept of that thing, and that this apprehension must be distinguished from the intellect’s act of compounding, in judgments, the aspects of things so apprehended: it is only through a fallible, and extended process of making such judgments that we arrive at more adequate concepts of things (see the final section of “Infallibility, Error, and Ignorance”). MacDonald also makes insightful, and complementary, observations along similar lines (pp. 183–84). However, though helpful, these points do not suffice to explain, let alone render defensible, Thomas’s claim of infallibility: why can’t some of our acts of intellective abstraction yield false cognitions (however rudimentary), in the sense Thomas specifies?; in other words; why can’t the agent intellect sometimes produce in the possible intellect forms which do not correspond to the forms that actually inhere, or even could inhere, in material things? I think that Stump is right to take this optimism to be one striking instance of Thomas’s general epistemic optimism rooted in his conviction that God designed our cognitive faculties (Stump, “Foundations of Knowledge,” pp. 145–48).The interpretation of his intellective abstraction provided here complements Stump’s insight. For it, in effect, elaborates how Aquinas’s theistic metaphysics grounds his epistemic optimism about the first operation of our intellect. In particular, it explains how the agent intellect, as the human participating likeness in the divine light of understanding, has the active potency to order phantasms in such a way that it can produce in the possible intellect intelligible species which are determinate likenesses of the particular material things of which we have experience (cf. Section III iv, below). Examining his distinction between sensible and intellectual cognition, and his account of the way the former, in phantasms, supplies the data for intellective abstraction, will lead us to reassess the nature of Thomas’s antinativism—arguably the most important historical and philosophical legacy of his cognitive psychology.

While there is a growing literature on “dark traits” (i.e., socially aversive traits), there has been a lack of integration with the burgeoning research literature on positive traits and fulfilling and growth-oriented outcomes in life. To help move the field toward greater integration, we contrasted the nomological network of the Dark Triad (a well-studied cluster of socially aversive traits) with the nomological network of the Light Triad, measured by the 12-item Light Triad Scale (LTS). The LTS is a first draft (...) measure of a loving and beneficent orientation toward others (“everyday saints”) that consists of three facets: Kantianism (treating people as ends unto themselves), Humanism (valuing the dignity and worth of each individual), and Faith in Humanity (believing in the fundamental goodness of humans). Across four demographically diverse samples (N = 1,518), the LTS demonstrated excellent reliability and validity, predicting life satisfaction and a wide range of growth-oriented and self-transcendent outcomes above and beyond existing measures of personality. In contrast, the Dark Triad was negatively associated with life satisfaction and growth-oriented outcomes, and showed stronger linkages to selfish, exploitative, aggressive, and socially aversive outcomes. This exploratory study of the contrasting nomological networks of the Light vs. Dark Triad provides several ways forward for more principled and data driven approaches to explore both the malevolent and benefice...

Pragmatism’s star in the field of rhetorical studies continues to rise, with more and more scholars mining the depths of figures such as Dewey, James, Addams, and beyond for rhetorically useful material. Part of the challenge comes from the complex historical context that such thinkers are embedded in; another challenge stems from pragmatism’s own commitment to praxis over the production of abstract—and all too often academic—theories divorced from the historical-material conditions of their emergence. Often, its best thinkers are those who (...) both engage in political practice and guide criticism instead of those who exclusively write scholarly books removed from the world of praxis.

This textbook is designed for an Introduction to Proofs course organized around the themes of number and space. Concepts are illustrated using both geometric and number examples, while frequent analogies and applications help build intuition and context in the humanities, arts, and sciences. Sophisticated mathematical ideas are introduced early and then revisited several times in a spiral structure, allowing students to progressively develop rigorous thinking. Throughout, the presentation is enlivened with whimsical illustrations, apt quotations, and glimpses of mathematical history and (...) culture. Early chapters integrate an introduction to sets, logic, and beginning proof techniques with a first exposure to more advanced mathematical structures. The middle chapters focus on equivalence relations, functions, and induction. Carefully chosen examples elucidate familiar topics, such as natural and rational numbers and angle measurements, as well as new mathematics, such as modular arithmetic and beginning graph theory. The book concludes with a thorough exploration of the cardinalities of finite and infinite sets and, in two optional chapters, brings all the topics together by constructing the real numbers and other complete metric spaces. Designed to foster the mental flexibility and rigorous thinking needed for advanced mathematics, Introduction to Mathematics suits either a lecture-based or flipped classroom. A year of mathematics, statistics, or computer science at the university level is assumed, but the main prerequisite is the willingness to engage in a new challenge. (shrink)

This chapter aims to illuminate ways in which hope was significant in the philosophy of classical Greece. Although ancient Greek philosophies contain few dedicated and systematic expositions on the nature of hope, they nevertheless include important remarks relating hope to the good life, to reason and deliberation, and to psychological phenomena such as memory, imagination, fear, motivation, and pleasure. After an introductory discussion of Hesiod and Heraclitus, the chapter focuses on Plato and Aristotle. Consideration is given both to Plato’s direct (...) comments on hope and to the narrative contexts of his dialogues, with analysis of Plato’s positive and negative representations of hope, hope’s relationship to reason, and Plato’s more psychological approach in the Philebus, where hope finds a place among memory, recollection, pleasure, and pain. The chapter then reviews Aristotle’s discussions of confidence, hope, and courage, observing that although Aristotle does not mention hope as a virtue, he does note its importance to human agency and deliberation and as a foundation for the further development of virtue. The chapter concludes that discussions surrounding hope in ancient Greek philosophy are rich and challenging and can serve as a lively stimulus to further exploration of the concept of hope.

Say that space is ‘gunky’ if every part of space has a proper part. Traditional theories of gunk, dating back to the work of Whitehead in the early part of last century, modeled space in the Boolean algebra of regular closed subsets of Euclidean space. More recently a complaint was brought against that tradition in Arntzenius and Russell : Lebesgue measure is not even finitely additive over the algebra, and there is no countably additive measure on the algebra. Arntzenius advocated (...) modeling gunk in measure algebras instead—in particular, in the algebra of Borel subsets of Euclidean space, modulo sets of Lebesgue measure zero. But while this algebra carries a natural, countably additive measure, it has some unattractive topological features. In this paper, we show how to construct a model of gunk that has both nice rudimentary measure-theoretic and topological properties. We then show that in modeling gunk in this way we can distinguish between finite dimensions, and that nothing in lost in terms of our ability to identify points as locations in space. (shrink)

The global pandemic has intensified the risk of moral distress due to increased demands on already limited human resources and uncertainty of the pandemic’s trajectory. Nurses commonly experience moral distress: a conflict between the morally correct action and what they are required or capable of doing. Effective moral distress interventions are rare. For this reason, our team conducted a multi-phase research study to develop a moral distress intervention for pediatric critical care nurses. In this article, we discuss our multi-phase approach (...) to develop a moral distress intervention—proactive, interdisciplinary meeting. Our proposed intervention is a sequential compilation of empirical work couched within a relational ethics lens thus should point to enhanced potential for intervention effectiveness. (shrink)

Philosopher’s judgements on the philosophical value of Tarski’s contributions to the theory of truth have varied. For example Karl Popper, Rudolf Carnap, and Donald Davidson have, in their different ways, celebrated Tarski’s achievements and have been enthusiastic about their philosophical relevance. Hilary Putnam, on the other hand, pronounces that “[a]s a philosophical account of truth, Tarski’s theory fails as badly as it is possible for an account to fail.” Putnam has several alleged reasons for his dissatisfaction,1 but one of them, (...) the one I call the modal objection (cf. Raatikainen 2003), has been particularly influential. In fact, very similar objections have been presented over and over again in the literature. Already in 1954, Arthur Pap had criticized Tarski’s account with a similar argument (Pap 1954). Moreover, both Scott Soames (1984) and John Etchemendy (1988) use, with an explicit reference to Putnam, similar modal arguments in relation to Tarski. Richard Heck (1997), too, shows some sympathy for such considerations. Simon Blackburn (1984, Ch. 8) has put forward a related argument against Tarski. Recently, Marian David has criticized Tarski’s truth definition with an analogous argument as well (David 2004, p. 389-390).2 This line of argument is thus apparently one of the most influential critiques of Tarski. It is certainly worthy of serious attention. Nevertheless, I shall argue that, given closer scrutiny, it does not present such an acute problem for the Tarskian approach to truth as many philosophers think. But I also believe that it is important to understand clearly why this is so. Moreover, I think that a careful consideration of the issue illuminates certain important but somewhat neglected aspects of the Tarskian approach. (shrink)

The Pragmatism Reader is the essential anthology of this important philosophical movement. Each selection featured here is a key writing by a leading pragmatist thinker, and represents a distinctively pragmatist approach to a core philosophical problem. The collection includes work by pragmatism's founders, Charles Peirce, William James, and John Dewey, as well as seminal writings by mid-twentieth-century pragmatists such as Sidney Hook, C. I. Lewis, Nelson Goodman, Rudolf Carnap, Wilfrid Sellars, and W.V.O. Quine. This reader also includes the most important (...) work in contemporary pragmatism by philosophers like Susan Haack, Cornel West, Hilary Putnam, Richard Rorty, Cheryl Misak, and Robert Brandom. Each selection is a stand-alone piece--not an excerpt or book chapter--and each is presented fully unabridged. The Pragmatism Reader challenges the notion that pragmatism fell into a midcentury decline and was dormant until the advent of "neopragmatism" in the 1980s. This comprehensive anthology reveals a rich and highly influential tradition running unbroken through twentieth-century philosophy and continuing today. It shows how American pragmatist philosophers have contributed to leading philosophical debates about truth, meaning, knowledge, experience, belief, existence, justification, and freedom. Covers pragmatist philosophy from its origins to today Features key writings by the leading pragmatist thinkers Demonstrates the continuity and enduring influence of pragmatism Challenges prevailing notions about pragmatism Includes only stand-alone pieces, completely unabridged Reflects the full range of pragmatist themes, arguments, concerns, and commitments.

Religious fictionalism is the theory that it is morally and intellectually legitimate to affirm religious sentences and to engage in public and private religious practices, without believing the content of religious claims. This article discusses the main features of fictionalism, contrasts hermeneutic, and revolutionary kinds of fictionalism and explores possible historical and recent examples of religious fictionalism. Such examples are found in recent theories of faith, pragmatic approaches to religion, and mystical traditions in religious theology.

"F. A. Hayek and the Epistemology of Politics is an exploration of an important problem that has largely been ignored: the problem of policymaker ignorance, and the limits of political epistemology. Scott Scheall explores Hayek's attitude to the philosophy of science and political philosophy, arguing that Hayek defended a philosophy of science that implied certain potential dangers of politicized science, and that his political philosophy established the potential dangers of misapplying scientific methods and results to matters of public policy. (...) The book offers an explanation for why policymaking often fails and why constituents, whatever their political affiliations, are so often disappointed with political leaders. In this primarily philosophical examination of his work, Hayek's ideas are not merely discussed, analysed, and contextualized, but extended; the book both draws and defends previously unrecognized implications from the Hayekian canon. The book also explores the historical context within which these ideas flourished. The book will be of interest to scholars and researchers of the works of F.A. Hayek, policymakers, and to those of all political, philosophical, and social-scientific persuasions"--. (shrink)

O primeiro artigo, intitulado “O jovem Diderot e o ceticismo dos Pensamentos”, foi publicado na revista Dois Pontos, em sua edição dedicada ao tema do ceticismo (cf. PIVA, 2007), e limitou-se a uma análise minuciosa do problema da postura cética nos Pensamentos filosóficos, de 1746. O presente artigo, por seu turno, examina duas questões fundamentais, (...) desta vez em O passeio do cético ou As alamedas, de 1747, último livro em que o ceticismo é evocado com destaque pelo enciclopedista, dois anos antes de ele render-se definitivamente ao materialismo ateu: 1) a interpretação que Diderot desenvolve do ceticismo e 2) sua posição diante dele. Já o terceiro e derradeiro texto da tríade examinará – evidentemente, numa próxima oportunidade – a presença do ceticismo no pensamento diderotiano da maturidade, ou seja, no período que se inicia em 1749, com a redação da Carta sobre os cegos, quando a questão da dúvida cética passa a perder em suas obras a relevância que tinha na origem de suas reflexões, mudando, até mesmo, de registro.

We propose a new approach to positive modal logics, hereby called anodic modal logics. Our treatment is completely positive since the language has neither negation nor any falsum or minimal particle. The elimination of the minimal particle of the language requires introducing the new concept of factual sets and factual deductions which permit us to talk about deductions in the actual world. We start from a positive fragment of the standard system K, denoted by K⊃, ∧, ◊, which is a (...) bimodal system with □ and ◊ as primitive. This system is then extended to a class of fragments of the Lemmon and Scott systems (cf. (Lemmon et al., 1977)), denoted by K⊃, ∧, ◊ + Gk;l;m;n + Gm;n;k;l. It is shown that such classes of systems are characterized with respect to the usual Kripke-style semantics. The proof is by way of a Henkin-style construction, with “possible worlds” being taken to be prime theories as introduced in the modal context by J. M. Dunn in (Dunn, 1995). We also obtain a surprising limiting result showing that the incompleteness phenomenon in modal logic is independent of negation. (shrink)

ABSTRACT This article addresses the growing literature in critical race studies, which holds that racism is permanent or incurable, and that by adopting this pessimistic view of racism, we can enact improved and healthier racialized lives. I argue that the focus on curing anti-Black racism, and the failure to do so in the civil rights era and its aftermath has left people of all races, to varying degrees, stuck in pessimistic states of racialized anger, resentment, guilt, and shame. These pessimistic (...) states have brought about an additional level of oppression for targets of racialized oppression. I call it “meta-oppression,” and it is the oppression of being oppressed. I argue that this oppression has exacerbated the effects of the social disease of racism, and it has literally affected the physiologies of many African Americans. This article provides a diagnosis of these existential and physiological states of meta-oppression and a clarification of its characteristics. This diagnosis is an initial step in a larger project of formulating and enacting effective treatments for it. I then argue that meta-oppression is a helpful diagnostic tool for clarifying the characteristics and ramifications on Blacks of US systemic racism during the post–civil rights movement period. I aim to establish meta-oppression as an existential and physiological condition that requires attention so as to expand the social imaginations of people of color and to allow us to engage in more systemic joyful affirmations of our racialized lives while still living within racist conditions.

History of science and philosophy of science have experienced a somewhat turbulent relationship over the last century. At times it has been said that philosophy needs history, or that history needs philosophy. Very occasionally, something entirely new is said to need them both. Often, however, their relationship is seen as little more than a marriage of convenience. This article explores that marriage by analyzing the citations of over 7,000 historians, philosophers, and sociologists of science. The data reveal that a small (...) but tightly-knit bridge does exist between the disciplines, and raises suggestions about how to understand that bridge in a more nuanced fashion. (shrink)

Let κ be a singular cardinal. Karp's notion of a chain model of size κ is defined to be an ordinary model of size κ along with a decomposition of it into an increasing union of length cf. With a notion of satisfaction and -isomorphism such models give an infinitary logic largely mimicking first order logic. In this paper we associate to this logic a notion of a dynamic EF-game which gauges when two chain models are chain-isomorphic. To this game (...) is associated a tree which is a tree of size κ with no κ-branches -branches). The measure of how non-isomorphic the models are is reflected by a certain order on these trees, called reduction. We study the collection of trees of size κ with no κ-branches under this notion and prove that when cf = ω this collection is rather regular; in particular it has universality number exactly κ+. Such trees are then used to develop a descriptive set theory of the space cf κ. The main result of the paper gives in the case of κ strong limit singular an exact connection between the descriptive set-theoretic complexity of the chain isomorphism orbit of a model, the reduction order on the trees and winning strategies in the corresponding dynamic EF games. In particular we obtain a neat analog of the notion of Scott watershed from the Scott analysis of countable models. (shrink)

The basic purpose of this essay, the first of an intended pair, is to interpret standard von Neumann quantum theory in a framework of iterated measure algebraic truth for mathematical (and thus mathematical-physical) assertions — a framework, that is, in which the truth-values for such assertions are elements of iterated boolean measure-algebras (cf. Sections 2.2.9, 5.2.1–5.2.6 and 5.3 below).The essay itself employs constructions of Takeuti's boolean-valued analysis (whose origins lay in work of Scott, Solovay, Krauss and others) to provide (...) a metamathematical interpretation of ideas sometimes considered disparate, heuristic, or simply ill-defined: the collapse of the wave function, for example; Everett's many worlds'-construal of quantum measurement; and a natural product space of contextual (nonlocal) hidden variables.

What are the objects of science? Are they just the things in our scientific experiments that are located in space and time? Or does science also require that there be additional things that are not located in space and time? Using clear examples, these are just some of the questions that Scott Berman explores as he shows why alternative theories such as Nominalism, Contemporary Aristotelianism, Constructivism, and Classical Aristotelianism, fall short. He demonstrates why the objects of scientific knowledge need (...) to be not located in space or time if they are to do the explanatory work scientists need them to do. The result is a contemporary version of Platonism that provides us with the best way to explain what the objects of scientific understanding are, and how those non-spatiotemporal things relate to the spatiotemporal things of scientific experiments, as well as everything around us, including even ourselves.
