We propose a novel type of low distortion radial embedding which focuses on one specific entity and its closest neighbors. Our embedding preserves near-exact distances to the focus entity and aims to minimize distortion between the other entities. We present an interactive exploration tool SolarView which places the focus entity at the center of a "solar system" and embeds its neighbors guided by concentric circles. SolarView provides an implementation of our novel embedding and several state-of-the-art dimensionality reduction and embedding techniques, (...) which we adapted to our setting in various ways. We experimentally evaluated our embedding and compared it to these state-of-the-art techniques. The results show that our embedding competes with these techniques and achieves low distortion in practice. Our method performs particularly well when the visualization, and hence the embedding, adheres to the solar system design principle of our application. Nonetheless - as with all dimensionality reduction techniques - the distortion may be high. We leverage interaction techniques to give clear visual cues that allow users to accurately judge distortion. We illustrate the use of SolarView by exploring the high-dimensional metric space of bibliographic entity similarities. (shrink)

In this position paper, we describe a number of methodological and philosophical challenges that arose within our interdisciplinary Digital Humanities project CatVis, which is a collaboration between applied geometric algorithms and visualization researchers, data scientists working at OCLC, and philosophers who have a strong interest in the methodological foundations of visualization research. The challenges we describe concern aspects of one single epistemic need: that of methodologically securing (an increase in) trust in visualizations. We discuss the lack of ground truths in (...) the (digital) humanities and argue that trust in visualizations requires that we evaluate visualizations on the basis of ground truths that humanities scholars themselves create. We further argue that trust in visualizations requires that a visualization provides provable guarantees on the faithfulness of the visual representation and that we must clearly communicate to the users which part of the visualization can be trusted and how much. Finally, we discuss transparency and accessibility in visualization research and provide measures for securing transparency and accessibility. (shrink)

Gregory Bateson’s career from anthropologist, through his development of cybernetics and systems theory, to developing ideas around ‘the sacred’, has parallels with Roy Bhaskar’s intellectual journey. This paper proposes that as well as Bateson’s theory of cybernetics and systemic thought making a contribution to basic and dialectic critical realism, his final and posthumously published Angels Fear: Towards and Epistemology of the Sacred adds to our understanding of Bhaskar’s metaReality. Similarities between the development of Bateson’s work from 1936 to 1987 and (...) Bhaskar’s work from 1975 to 2016 enable the development of theory that adds to both of their respective appreciations of metaReality and the sacred. Thus, by starting a conversation between Bateson and Bhaskar, we can develop a higher order understanding of the world than proposed by Bhaskar’s metaReality alone. (shrink)

In an essay on performance-enhancing drugs, author Chuck Klosterman (2007) argues that the category of enhancers extends from hallucinogens used to inspire music to steroids used to strengthen athletes—and he criticizes those who would excuse one means of enhancement while railing against the other as a form of cheating: After the summer of 1964, the Beatles started taking serious drugs, and those drugs altered their musical performance. Though it may not have been their overt intent, the Beatles took performance-enhancing drugs. (...) And . . . absolutely no one holds it against them. No one views “Rubber Soul” and “Revolver” as “less authentic” albums, despite the fact that they would not (and probably could .. (shrink)

This book reports recent landmark developments and the state of the art in NDS science in psychological theory and research.

Creativity: Theory, History, Practice offers important new perspectives on creativity in the light of contemporary critical theory and cultural history. Innovative in approach as well as argument, the book crosses disciplinary boundaries and builds new bridges between the critical and the creative. It is organized in four parts: · Why creativity now? offers much-needed alternatives to both the Romantic stereotype of the creator as individual genius and the tendency of the modern creative industries to treat everything as a commodity. · (...) Defining creativity, creating definitions traces the changing meaning of "create" from religious ideas of divine creation from nothing to advertising notions of concept creation. It also examines the complex history and extraordinary versatility of terms such as imagination, invention, inspiration and originality. · Creation as myth, story, metaphor begins with modern re-telling of early African, American and Australian creation myths and -picking up Biblical and evolutionary accounts along the way - works round to scientific visions of the Big Bang, bubble universes and cosmic soup. · Creative practices, cultural processes is a critical anthology of materials, chosen to promote fresh thinking about everything from changing constructions of "literature" and "design" to artificial intelligence and genetic engineering. Rob Pope takes significant steps forward in the process of rethinking a vexed yet vital concept, all the while encouraging and equipping readers to continue the process in their own creative or "re-creative" ways. Creativity: Theory, History, Practice is invaluable for anyone with a live interest in exploring what creativity has been, is currently, and yet may be. (shrink)

In an increasingly complex world with increasingly powerful organisations it seems inevitable that society – or groups in society – would become anxious about whether these organisations could be encouraged to match that power with an appropriate responsibility. This is the function of accountability – to require individuals and organisations to present an account of those actions for which society holds them – or would wish to hold them – responsible. And the history of social accounting, at its most fundamental, (...) is a history of attempts to develop this accountability. It seems to me that the widespread and systematic practice of social and environmental accounting is a deeply essential element in any well‐functioning, complex democracy. The corollary is that the absence of such mechanisms raises fundamental questions about the nature of modern democracies. This article briefly outlines what I believe to be the three strands of social accounting. It then identifies a few of the lessons that we may be able to learn from current experience and, in particular, how social accounting is related to accountability, democracy and sustainability. The central issue of the tension between accountability and control is touched upon: I then illustrate how the stakeholder model can be used to help define the social account, and conclude with a few words on attestation.

Despite widespread recognition of an emergent politics of data in our midst, we strikingly lack a political theory of data. We readily acknowledge the presence of data across our political lives, but we often do not know how to conceptualize the politics of all those data points—the forms of power they constitute and the kinds of political subjects they implicate. Recent work in numerous academic disciplines is evidence of the first steps toward a political theory of data. This article maps (...) some limits of this emergent literature with an eye to enriching its theoretical range. The literature on data politics, both within political theory and elsewhere, has thus far focused almost exclusively on the algorithm. This article locates a further dimension of data politics in the work of formatting technology or, more simply, formats. Formats are simultaneously conceptual and technical in the ways they define what can even count as data, and by extension who can count as data and how they can count. A focus on formats is of theoretical value because it provides a bridge between work on the conceptual contours of categories and the technology-centric literature on algorithms that tends to ignore the more conceptual dimensions of data technology. The political insight enabled by format theory is shown in the context of an extended interrogation of the politics of racialized redlining. (shrink)

The linguistic turn is a central aspect of Richard Rorty’s philosophy, informing his early critiques of foundationalism in Philosophy and the Mirror of Nature and subsequent critiques of authoritarianism in Contingency, Irony, and Solidarity. It is argued that we should interpret the linguistic turn as a methodological suggestion for how philosophy can take a non-foundational perspective on normativity. It is then argued that although Rorty did not succeed in explicating normativity without foundations (or authority without authoritarianism), we should take seriously (...) the ambition motivating his project. But taking that ambition seriously may require reconsidering the linguistic turn. (shrink)

We show that three fundamental information-theoretic constraints -- the impossibility of superluminal information transfer between two physical systems by performing measurements on one of them, the impossibility of broadcasting the information contained in an unknown physical state, and the impossibility of unconditionally secure bit commitment -- suffice to entail that the observables and state space of a physical theory are quantum-mechanical. We demonstrate the converse derivation in part, and consider the implications of alternative answers to a remaining open question about (...) nonlocality and bit commitment. (shrink)

This article examines how the availability of Big Data, coupled with new data analytics, challenges established epistemologies across the sciences, social sciences and humanities, and assesses the extent to which they are engendering paradigm shifts across multiple disciplines. In particular, it critically explores new forms of empiricism that declare ‘the end of theory’, the creation of data-driven rather than knowledge-driven science, and the development of digital humanities and computational social sciences that propose radically different ways to make sense of culture, (...) history, economy and society. It is argued that: Big Data and new data analytics are disruptive innovations which are reconfiguring in many instances how research is conducted; and there is an urgent need for wider critical reflection within the academy on the epistemological implications of the unfolding data revolution, a task that has barely begun to be tackled despite the rapid changes in research practices presently taking place. After critically reviewing emerging epistemological positions, it is contended that a potentially fruitful approach would be the development of a situated, reflexive and contextually nuanced epistemology.

Political CSR scholars argue that multi-stakeholder initiatives (MSIs) should be designed to facilitate deliberation among corporations, civil society groups, and others affected by corporate conduct for their decisions to be considered democratically legitimate. However, critics argue that decisions reached within deliberative MSIs will lack democratic legitimacy so long as corporations are granted a role in helping to make them. If the critics are correct, it leads to a paradox. Corporations must be excluded from holding decision-making authority within MSIs if they (...) are to function as democratically legitimate regulatory institutions at a global level. However, this risks severely diminishing the incentive of corporations to support and participate within MSIs, which often depend heavily for their success on the visibility provided them by corporate participants. In this paper, I argue that this apparent paradox should be considered irrelevant to the future study of MSIs since it is both unnecessary and impractical for researchers to focus on establishing democratically legitimate systems of governance within them. Instead, I recommend an approach informed by three touchstones of pragmatic philosophy to guide their future study—a criterion of usefulness, wariness of category disputes and commitment to experimentalism. I conclude by drawing on research in political science and social psychology that demonstrates an important practical role for deliberation within such organizations, arguing that researchers must zero in on the role that inclusive deliberation can play in bolstering their effectiveness as regulatory instruments.

According to the theory of intrinsic value and moral standing called the ‘substance view,’ what makes it prima facie seriously wrong to kill adult human beings, human infants, and even human fetuses is the possession of the essential property of the basic capacity for rational moral agency – a capacity for rational moral agency in root form and thereby not remotely exercisable. In this critique, I cover three distinct reductio charges directed at the substance view's conclusion that human fetuses have (...) the same intrinsic value and moral standing as adult human beings. After giving consideration to defenders of the substance view's replies to these charges, I then critique each of them, ultimately concluding that none is successful. Of course, in order to understand all of these things – the reductio charges, defenders of the substance view's replies to them, and my criticisms of their replies – one must have a better understanding of the substance view as well as its defense. Accordingly, I address the substance view's understanding of rational moral agency as well as present its defense. (shrink)

This article is about a sidebar in James Gibson's last book, The ecological approach to visual perception. In this sidebar, Gibson, the founder of the ecological perspective of perception and action, argued that to perceive an affordance is not to classify an object. Although this sidebar has received scant attention, it is of great significance both historically and for recent discussions about specificity, direct perception, and the functions of the dorsal and ventral streams. It is argued that Gibson's acknowledgment of (...) Wittgenstein's ideas of classification suggests a limited scope of his theory of direct perception?it cannot account for the classification of objects. The implications for both the specification debate and theorizing about the brain's dorsal and ventral pathways are explored. Based on a recent ecological conception of information and direct perception, we ultimately argue that both affordance perception and classification are direct. (shrink)

Some people (e.g., Drs. Paul and Susan Lim) and, with them, organizations (e.g., the National Embryo Donation Center) believe that, morally speaking, the death of a frozen human embryo is a very bad thing. With such people and organizations in mind, the question to be addressed here is as follows: if one believes that the death of a frozen embryo is a very bad thing, ought, morally speaking, one prevent the death of at least one frozen embryo via embryo adoption? (...) By way of a three‐premise argument, one of which is a moral principle first introduced by Peter Singer, my answer to this question is: at least some of those who believe this ought to. (Just who the “some” are is identified in the paper.) If this is correct, then, for said people, preventing the death of a frozen embryo via embryo adoption is not a morally neutral matter; it is, instead, a morally laden one. Specifically, their intentional refusal to prevent the death of a frozen embryo via embryo adoption is, at a minimum, morally criticizable and, arguably, morally forbidden. Either way, it is, to one extent or another, a moral failing. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy of Music Education Review 12.1 (2004) 60-63 [Access article in PDF] Response to Bennett Reimer, "Once More with Feeling: Reconciling Discrepant Accounts of Musical Affect" Constantijn Koopman University of Nijmegen and Royal Conservatory of the Hague, The Netherlands Bennett Reimer has pointed out the crucial distinction between intrinsic and extrinsic meaning or, in his terminology, between inherent and delineated meaning. He has eloquently described how feeling in (...) music can be both of the inherent type and of the delineated type and has argued that both types of meaning can coexist. There is no point in denying the validity of either of them; rather the challenge is to develop a view which allows us to combine both perspectives of musical meaning into a unified musical practice.As far as I am concerned, Reimer has succeeded in his reconciliatory approach. Therefore, rather than providing criticism, I would like further to elaborate on the subject. First, I shall examine the difference between the two types of meaning Reimer has illustrated in his examples: feeling as a part of inherent meaning and feeling as portrayed or represented. Then, I shall briefly discuss the problem of articulating these two types of meaning and its educational implications.When reflecting on inherent and delineated meaning, I find that the dichotomy [End Page 60] goes beyond the opposition between intrinsic and extrinsic. We are also dealing with different versions of the concept of meaning; different meanings of 'meaning' so to speak. In the case of feelings, actions, or objects portrayed in music we have a rather unproblematic use of the meaning concept-meaning as reference. Music functions as a meaning bearer that directs our attention to something beyond itself. Musical structure is used to represent something that exists independently of music. With Charles S. Peirce, we might say that it serves the function of an "icon." The iconic sign has a form which is similar to the thing it denotes.1 Similarity may have the form of direct resemblance but it may also may be based on analogy. I guess that both kinds of portrayal were present in the Chinese swamp battle piece. Battle sounds can easily be imitated by musical instruments and violent movement and feelings can be represented by analogous tonal movement.With inherent meaning, things are different. Feelings are not pointed to and represented by musical structure; instead they are experienced by the person who engages in music. This is in line, I suppose, with Reimer's exposition; not only does he say that feeling is contained and expressed in sounds but also that feeling is undergone by the performer and the listener. What precisely is the place of inherent feeling in music? Feelings are not contained in the sense that they require an act of decoding so that by interpreting the musical structure we can decipher its affective contents. Nor is it appropriate simply to declare that musical feelings are caused by musical perception. Such an explanation suggests that feelings are a secondary phenomenon in music, a sort of byproduct of musical cognition; first the music is conceived in a cognitive act, then feelings are released. But in fact feeling is much more directly and actively involved in musical experience; it is vital to the constitution of the musical object. For example, to appreciate the specific character and import of themes and motifs we have to sense their affective value. We realize the power of rhythms by feeling them in our body. Chords and chord progressions are perceived as subtle qualities of tension and release. Only by feeling the curve of tension and release can we appreciate how the work progresses-whether the music is moving forward or coming to closure, whether a climax is prepared or there is consolidation, whether a case of closure is partial or final. Likewise, the perception of contrasting musical episodes-like soft versus rough, supple versus stubborn, warm versus frigid-involves the participation of feeling. In short, the function of feeling contributes a major part to the constitution of the musical... (shrink)

This paper presents a longue durée account of the discursive emergence of ‘the market'. It seeks to develop understanding of the ‘crisis system' by showing that the crises of the present have their origins earlier than some critical realist scholars have suggested and can be better understood by the theorization of the generative mechanisms that emerged from the economic and political chaos of the early 1600s. Critical discourse analysis (CDA) is employed to show that in the context of the emergence (...) of capitalism in England, these generative mechanisms resulted in the meaning of the word ‘market’ slipping loose of the geo-spatial semiotic bounds by which it had commonly been delineated – i.e. as a physical space in a town or city where goods were bartered or sold – and being re-semioticised to refer to abstract space where all acts of capitalist economic exchange, including those impacting upon the natural world, take place.

Some conspicuous characteristics of argumentation as we all know this phenomenon from our shared everyday experiences are in my view vital to its theoretical treatment because they should have methodological consequences for the way in which argumentation research is conducted. To start with, argumentation is in the first place a communicative act complex, which is realized by making functional verbal communicative moves.

Philosophical reflection on quantum field theory has tended to focus on how it revises our conception of what a particle is. However, there has been relatively little discussion of the threat to the "reality" of particles posed by the possibility of inequivalent quantizations of a classical field theory, i.e., inequivalent representations of the algebra of observables of the field in terms of operators on a Hilbert space. The threat is that each representation embodies its own distinctive conception of what a (...) particle is, and how a "particle" will respond to a suitably operated detector. Our main goal is to clarify the subtle relationship between inequivalent representations of a field theory and their associated particle concepts. We also have a particular interest in the Minkowski versus Rindler quantizations of a free Boson field, because they respectively entail two radically different descriptions of the particle content of the field in the *very same* region of spacetime. We shall defend the idea that these representations provide *complementary descriptions* of the same state of the field against the claim that they embody completely *incommensurable theories* of the field.

In his paper, “Should the Numbers Count?" John Taurek imagines that we are in a position such that we can either save a group of five people, or we can save one individual, David. We cannot save David and the five. This is because they each require a life-saving drug. However, David needs all of the drug if he is to survive, while the other five need only a fifth each.Typically, people have argued as if there was a choice to (...) be made: either numbers matter, in which case we should save the greater number, or numbers don't matter, but rather there is moral value in giving each person an equal chance of survival, and therefore we should toss a coin. My claim is that we do not have to make a choice in this way. Rather, numbers do matter, but it doesn't follow that we should always save the greater number. And likewise, there is moral value in giving each person an equal chance of survival, but it doesn't follow that we should always toss a coin. (shrink)

If culture is defined as variation acquired and maintained by social learning, then culture is common in nature. However, cumulative cultural evolution resulting in behaviors that no individual could invent on their own is limited to humans, song birds, and perhaps chimpanzees. Circumstantial evidence suggests that cumulative cultural evolution requires the capacity for observational learning. Here, we analyze two models the evolution of psychological capacities that allow cumulative cultural evolution. Both models suggest that the conditions which allow the evolution of (...) such capacities when rare are much more stringent than the conditions which allow the maintenance of the capacities when common. This result follows from the fact that the assumed benefit of the capacities, cumulative cultural adaptation, cannot occur when the capacities are rare. These results suggest why such capacities may be rare in nature. (shrink)

In my articles ‘The Substance View: A Critique’ and ‘The Substance View: A Critique,’ I raise objections to the substance view, a theory of intrinsic value and moral standing defended by a number of contemporary moral philosophers, including Robert P.

In part one of my critique of the substance view, I raise reductio-style objections to the substance view's conclusion that the standard human fetus has the same intrinsic value and moral standing as (...) the standard adult human being, among other human beings. In part two, I raise objections to some of the premises invoked in support of that conclusion. Here, in part three, I raise objections to Henrik Friberg-Fernros's attempt to rebut some of the aforementioned objections. (shrink)

A flourishing literature assesses how sustainable business models create and capture value in socio-ecological systems. Nevertheless, we still know relatively little about how the organization of sustainable business models—of which cross-sector partnerships represent a core and distinctive mechanism—can support socio-ecological resilience. We address this knowledge gap by taking a complex adaptive systems (CAS) perspective. We develop a framework that identifies the key strategic, institutional, and learning elements of partnerships that sustainable business models rely on to support socio-ecological resilience. With our (...) analytical framework, we underpin the importance of assessing sustainable business initiatives in terms of their impact on resilience at the level of socio-ecological systems, not just of organizations. Therefore, we reveal how cross-sector partnerships provide the organizational support for sustainable business models to support socio-ecological resilience. By combining the key features of CAS and the key elements of partnerships, we provide insight into the formidable task of designing cross-sector partnerships so that they support socio-ecological resilience and avoid unintended consequences.

This paper explores the relation between metaethical reflection and value experience, and does so by focusing on robust realism. Robust realism is typically criticized for its ontological and epistemological commitments. In this paper, however, we hope to shed new critical light on the plausibility of the theory by using two concepts – ‘reification’ and ‘alienation’ – that have their origin in critical social theory. We use the concept of ‘reification’ as an interpretative lens to look at robust realism and show (...) that it is reifying in two respects: it turns values into things, and, correspondingly, turns human agents into disengaged observers of those things. This analysis is then used to argue that robust realism is alienating in the sense that it distances us from the world that presents itself to us in value experience, and that it separates us from what we call our engaged responsiveness. We also argue that its alienating effects give us good reason to reject the theory. (shrink)

'Shades of Goodness' is aimed at readers interested in moral theories, and particularly those wishing to construct or defend a moral theory.

Emotion, Sense, Experience calls on historians of emotions and the senses to come together in serious and sustained dialogue. The Element outlines the deep if largely unacknowledged genealogy of historical writing insisting on a braided history of emotions and the senses; explains why recent historical treatments have sometimes profitably but nonetheless unhelpfully segregated the emotions from the senses; and makes a compelling case for the heuristic and interpretive dividends of bringing emotions and sensory history into conversation. Ultimately, we envisage a (...) new way of understanding historical lived experience generally, as a mutable product of a situated world-brain-body dynamic. Such a project necessarily points us towards new interdisciplinary engagement and collaboration, especially with social neuroscience. Unpicking some commonly held assumptions about affective and sensory experience, we re-imagine the human being as both biocultural and historical, reclaiming the analysis of human experience from biology and psychology and seeking new collaborative efforts.

Entanglement has long been the subject of discussion by philosophers of quantum theory, and has recently come to play an essential role for physicists in their development of quantum information theory. In this paper we show how the formalism of algebraic quantum field theory (AQFT) provides a rigorous framework within which to analyse entanglement in the context of a fully relativistic formulation of quantum theory. What emerges from the analysis are new practical and theoretical limitations on an experimenter's ability to (...) perform operations on a field in one spacetime region that can disentangle its state from the state of the field in other spacelike-separated regions. These limitations show just how deeply entrenched entanglement is in relativistic quantum field theory, and yield a fresh perspective on the ways in which the theory differs conceptually from both standard non-relativistic quantum theory and classical relativistic field theory.

Combining methods in social scientific research has recently gained momentum through a research strand called Mixed Methods Research. This approach, which explicitly aims to offer a framework for combining methods, has rapidly spread through the social and behavioural sciences, and this article offers an analysis of the approach from a field theoretical perspective. After a brief outline of the MMR program, we ask how its recent rise can be understood. We then delve deeper into some of the specific elements that (...) constitute the MMR approach, and we engage critically with the assumptions that underlay this particular conception of using multiple methods. We conclude by offering an alternative view regarding methods and method use. (shrink)

William James's writings on morality form a vexed collection. Most philosophers regard James as having contributed primarily to epistemology, metaphysics, and psychology, viewing his moral philosophy as secondary, derivative, and accordingly uninteresting for contemporary debates. Among James's writings on moral matters, surely the most infamous is "The Will to Believe." Often read as primarily a contribution to epistemology or philosophy of religion,1 a number of critics spanning well over one hundred years of readership argue that "The Will to Believe" attempts (...) to foist an incredible ethics of belief, one that is problematic in that it defends believing in precisely that which has not been credited as being...

Aesthesis, the classical term for sensing and perceiving, is at the heart of innumerable problems that plague global society. The purpose of this article is to open a conversation on aesthesis. We survey the roots and relevance of aesthesis as a direct albeit contested relation and engagement with the world and with Others. From its pre-Socratic origins, aesthesis has been both a pragmatic, somatic concept, prompting a re-evaluation of the distinction between experience and abstraction. We trace its ongoing repression from (...) Plato through ‘western’ theories of formal Aesthetics. Drawing on a relational interpretation of Protagoras’ aesthesis, we argue that modern pragmatists and radical empiricists, as well as more contemporary critics of the ‘colonization’ of aesthesis (Mignolo and Vasquez) by formal Aesthetics recognize and develop the relational and ethical aspects of aesthesis. We consider the role of the body, affect, and of the intangible or virtual qualities of aesthesis. The ethics of obligations (Weil) in the polis (Arendt) shows how aesthesis informs politics despite its repression in favour of moral and legal norms. We argue this is relevant to contemporary crises such as xenophobia and ecocidal climate warming. (shrink)

Peter Lewis ([1997]) has recently argued that the wavefunction collapse theory of GRW (Ghirardi, Rimini and Weber [1986]) can only solve the problem of wavefunction tails at the expense of predicting that arithmetic does not apply to ordinary macroscopic objects. More specifically, Lewis argues that the GRW theory must violate the enumeration principle: that 'if marble 1 is in the box and marble 2 is in the box and so on through marble n, then all n marbles are in the (...) box' ([1997], p. 321). Ghirardi and Bassi ([1999]) have replied that it is meaningless to say that the enumeration principle is violated because the wavefunction Lewis uses to exhibit the violation cannot persist, according to the GRW theory, for more than a split second ([1999], p. 709). On the contrary, we argue that Lewis's argument survives Ghirardi and Bassi' s criticism unscathed. We then go on to show that, while the enumeration principle can fail in the GRW theory, the theory itself guarantees that the principle can never be empirically falsified, leaving the applicability of arithmetical reasoning to both micro- and macroscopic objects intact.

In his recent article On Relativity Theory and Openness of the Future (1991), Howard Stein proves not only that one can define an objective becoming relation in Minkowski spacetime, but that there is only one possible definition available if one accepts certain natural assumptions about what it is for becoming to occur and for it to be objective. Stein uses the definition supplied by his proof to refute an argument due to Rietdijk (1966, 1976), Putnam (1967) and Maxwell (1985, 1988) (...) that Minkowski spacetime leaves no room for objective becoming whatsoever. However, Stein's proof does not seem to go far enough. By considering only what events have become from the standpoint of any given event, Stein's uniqueness proof fails from the outset to allow for a more general kind of becoming whereby it is understood to occur from the standpoint of events on the particular worldlines followed by observers. This suggests that there may, after all, be more than one way to define objective becoming in Minkowski spacetime once each observer's worldline is allowed to figure in the definition. This suspicion is further aroused by two recent proposals for objective, worldline-dependent becoming due to Peacock (1992) and Muller (1992) who advocate ways of defining becoming that are not equivalent to the definition Stein's uniqueness proof delivers. Nevertheless, we show that Stein's uniqueness proofcan be extended in a natural way to cover this more general kind of becoming, provided one does not enrich standard Minkowski spacetime by privileging certain sets of worldlines over others in an unwarranted manner. Thus we aim to reinforce Stein's point that standard Minkowski spacetime does make room for objective becoming, but in essentially only one way, despite arguments and proposals to the contrary.

In this paper (which is, at best, a work in progress), I discuss different modes of scientific explanation identified by philosophers (Hempel, Salmon, Kitcher, Friedman, Hughes) and examine how well or badly they capture the "explanations" of phenomena that modern quantum theory provides.

Problems and prospects for structural explanation in quantum theory are also (...) discussed. (shrink)
