Classical mechanics and quantum mechanics are two of the most successful scientific theories ever discovered, and yet how they can describe the same world is far from clear: one theory is deterministic, the other indeterministic; one theory describes a world in which chaos is pervasive, the other a world in which chaos is absent. Focusing on the exciting field of 'quantum chaos', this book reveals that there is a subtle and complex relation between classical and quantum mechanics. It challenges the (...) received view that classical and quantum mechanics are incommensurable, and revives another, largely forgotten tradition due to Niels Bohr and Paul Dirac. By artfully weaving together considerations from the history of science, philosophy of science, and contemporary physics, this book offers a new way of thinking about intertheory relations and scientific explanation. It will be of particular interest to historians and philosophers of science, philosophically-inclined physicists, and interested non-specialists. (shrink)

Scientific models invariably involve some degree of idealization, abstraction, or nationalization of their target system. Nonetheless, I argue that there are circumstances under which such false models can offer genuine scientific explanations. After reviewing three different proposals in the literature for how models can explain, I shall introduce a more general account of what I call model explanations, which specify the conditions under which models can be counted as explanatory. I shall illustrate this new framework by applying it to the (...) case of Bohr's model of the atom, and conclude by drawing some distinctions between phenomenological models, explanatory models, and fictional models.

In semiclassical mechanics one finds explanations of quantum phenomena that appeal to classical structures. These explanations are prima facie problematic insofar as the classical structures they appeal to do not exist. Here I defend the view that fictional structures can be genuinely explanatory by introducing a model-based account of scientific explanation. Applying this framework to the semiclassical phenomenon of wavefunction scarring, I argue that not only can the fictional classical trajectories explain certain aspects of this quantum phenomenon, but also that (...) an explanation that does not make reference to these classical structures is, in a certain sense, deficient.

The aim of this paper is to examine in detail the similarities and dissimilarities between Werner Heisenberg’s account of closed theories and Thomas Kuhn’s model of scientific revolutions. My analysis draws on a little‐known discussion that took place between Heisenberg and Kuhn in 1963, in which Heisenberg, having just read Kuhn’s Structure of Scientific Revolutions, compares Kuhn’s views to his own account of closed theories. I conclude that while Heisenberg and Kuhn share a holist conception of theories, a revolutionary model (...) of theory change, and even a notion of incommensurability, their views diverge fundamentally when it comes to the issue of scientific realism. I show that, contrary to popular opinion, Heisenberg is not an instrumentalist, but rather a pluralistic realist. (shrink)

Despite widespread evidence that fictional models play an explanatory role in science, resistance remains to the idea that fictions can explain. A central source of this resistance is a particular view about what explanations are, namely, the ontic conception of explanation. According to the ontic conception, explanations just are the concrete entities in the world. I argue this conception is ultimately incoherent and that even a weaker version of the ontic conception fails. Fictional models can succeed in offering genuine explanations (...) by correctly capturing relevant patterns of counterfactual dependence and licensing correct inferences. Using the example of Newtonian force explanations of the tides, I show how, even in science, fiction can be a vehicle for truth. (shrink)

Recent work in quantum information science has produced a revolution in our understanding of quantum entanglement. Scientists now view entanglement as a physical resource with many important applications. These range from quantum computers, which would be able to compute exponentially faster than classical computers, to quantum cryptographic techniques, which could provide unbreakable codes for the transfer of secret information over public channels. These important advances in the study of quantum entanglement and information touch on deep foundational issues in both physics (...) and philosophy. This interdisciplinary volume brings together fourteen of the world's leading physicists and philosophers of physics to address the most important developments and debates in this exciting area of research. It offers a broad spectrum of approaches to resolving deep foundational challenges - philosophical, mathematical, and physical - raised by quantum information, quantum processing, and entanglement. This book is ideal for historians, philosophers of science and physicists"--Provided by publisher. (shrink)

We critically engage two traditional views of scientific data and outline a novel philosophical view that we call the pragmatic-representational view of data. On the PR view, data are representations that are the product of a process of inquiry, and they should be evaluated in terms of their adequacy or fitness for particular purposes. Some important implications of the PR view for data assessment, related to misrepresentation, context-sensitivity, and complementary use, are highlighted. The PR view provides insight into the common (...) but little-discussed practices of iteratively reusing and repurposing data, which result in many datasets’ having a phylogeny—an origin and complex evolutionary history—that is relevant to their evaluation and future use. We relate these insights to the open-data and data-rescue movements, and highlight several future avenues of research that build on the PR view of data. (shrink)

This book will be of particular interest to those philosophers, scientists, and mathematicians who are interested in the foundations of science.

In 2012, the Geological Time Scale, which sets the temporal framework for studying the timing and tempo of all major geological, biological, and climatic events in Earth’s history, had one-quarter of its boundaries moved in a widespread revision of radiometric dates. The philosophy of metrology helps us understand this episode, and it, in turn, elucidates the notions of calibration, coherence, and consilience. I argue that coherence testing is a distinct activity preceding calibration and consilience, and I highlight the value of (...) discordant evidence and trade-offs scientists face in calibration. The iterative nature of calibration, moreover, raises the problem of legacy data. (shrink)

How can black feminist and women of color feminist theoretical interventions help create frameworks for discerning agentic action in the context of power, oppression, and violence? In this paper, I explore the social dimension of agency and argue that intention is not just authored by the agent as a function of practical reasoning, but is also socially authored through others' discernment and translation of her action. Further, when facilitated by reasoning designed to reinforce and rationalize systems of domination, social authoring (...) systematically distorts the intentions of some agents. Although some theorists have argued that those agents whose intentions are not recognized by others are forced to exercise a diminished agency, I contend that this account obscures agency that is practiced despite or through conditions of oppression. As an alternative, I propose that feminist of color theory that examines the structural and existential erasures of women of color maps a conceptual space to help us better discern agentic action that is practiced by those subjects whose acts are defined away from them.

There is a growing recognition that fictions have a number of legitimate functions in science, even when it comes to scientific explanation. However, the question then arises, what distinguishes an explanatory fiction from a nonexplanatory one? Here I examine two cases—one in which there is a consensus in the scientific community that the fiction is explanatory and another in which the fiction is not explanatory. I shall show how my account of “model explanations” is able to explain this asymmetry, and (...) argue that realism—of a more subtle form—does have a role in distinguishing explanatory from non- explanatory fictions.

At the center of quantum chaos research is a particular family of models known as quantum maps. These maps illustrate an important “horizontal” dimension to model construction that has been overlooked in the literature on models. Three ways in which quantum maps are being used to clarify the relationship between classical and quantum mechanics are examined. This study suggests that horizontal models may provide a new and fruitful framework for exploring intertheoretic relations.

While the predominant focus of the philosophical literature on scientific modeling has been on single-scale models, most systems in nature exhibit complex multiscale behavior, requiring new modeling methods. This challenge of modeling phenomena across a vast range of spatial and temporal scales has been called the tyranny of scales problem. Drawing on research in the geosciences, I synthesize and analyze a number of strategies for taming this tyranny in the context of conceptual, physical, and mathematical modeling. This includes several strategies (...) that can be deployed in physical modeling, even when strict dynamical scaling fails. In all cases, I argue that having an adequate conceptual model—given both the nature of the system and the particular purpose of the model—is essential. I draw a distinction between depiction and representation, and use this research in the geosciences to advance a number of debates in the philosophy of modeling. (shrink)

Model-data symbiosis is the view that there is an interdependent and mutually beneficial relationship between data and models, whereby models are not only data-laden, but data are also model-laden or model filtered. In this paper I elaborate and defend the second, more controversial, component of the symbiosis view. In particular, I construct a preliminary taxonomy of the different ways in which theoretical and simulation models are used in the production of data sets. These include data conversion, data correction, data interpolation, (...) data scaling, data fusion, data assimilation, and synthetic data. Each is defined and briefly illustrated with an example from the geosciences. I argue that model-filtered data are typically more accurate and reliable than the so-called raw data, and hence beneficially serve the epistemic aims of science. By illuminating the methods by which raw data are turned into scientifically useful data sets, this taxonomy provides a foundation for developing a more adequate philosophy of data. (shrink)

Although predictive power and explanatory insight are both desiderata of scientific models, these features are often in tension with each other and cannot be simultaneously maximized. In such situations, scientists may adopt what I term a ‘division of cognitive labor’ among models, using different models for the purposes of explanation and prediction, respectively, even for the exact same phenomenon being investigated. Adopting this strategy raises a number of issues, however, which have received inadequate philosophical attention. More specifically, while one implication (...) may be that it is inappropriate to judge explanatory models by the same standards of quantitative accuracy as predictive models, there still needs to be some way of either confirming or rejecting these model explanations. Here I argue that robustness analyses have a central role to play in testing highly idealized explanatory models. I illustrate these points with two examples of explanatory models from the field of geomorphology. (shrink)

This article is a textual analysis of messages and themes in "Calvin and Hobbes," a comic strip nationally syndicated from 1985 to 1995. The article examines the content found in "Calvin and Hobbes" to determine underlying messages concerning ethics and values. Specifically, the messages are analyzed to determine under which category of metaethics-deontological, teleological, and virtue-they fall.

Most liberal political theorists of education argue that it is better to teach students to tolerate diversity, than to protect the potentially illiberal commitments of some members of the political communities. In fact, neither approach is wholly satisfying, yet they remain the focus of much political theorizing about education. This article suggests that this misguided focus is, in part, a consequence of a focus, by liberal political theorists of education, upon the 1987 Mozert v. Hawkins court case. Mozert raised serious (...) questions about the nature of toleration in liberal society, but from an educational standpoint, the Mozert case led political theorists to consider what curricular content is appropriate for liberal political education, rather than on the practices that democratic citizens must cultivate. I turn to Hannah Arendt to offer a critical account of the liberal responses to Mozert and then call for a theory of democratic education that fosters practices of democratic decision-making and has, as its aim, not merely to foster respect for diversity, but to allow future citizens to practice critical engagement with diversity.

Despite an enormous philosophical literature on models in science, surprisingly little has been written about data models and how they are constructed. In this paper, I examine the case of how paleodiversity data models are constructed from the fossil data. In particular, I show how paleontologists are using various model-based techniques to correct the data. Drawing on this research, I argue for the following related theses: first, the ‘purity’ of a data model is not a measure of its epistemic reliability. (...) Instead it is the fidelity of the data that matters. Second, the fidelity of a data model in capturing the signal of interest is a matter of degree. Third, the fidelity of a data model can be improved ‘vicariously’, such as through the use of post hoc model-based correction techniques. And, fourth, data models, like theoretical models, should be assessed as adequate for particular purposes. (shrink)

The fact that the same equations or mathematical models reappear in the descriptions of what are otherwise disparate physical systems can be seen as yet another manifestation of Wigner's “unreasonable effectiveness of mathematics.” James Clerk Maxwell famously exploited such formal similarities in what he called the “method of physical analogy.” Both Maxwell and Hermann von Helmholtz appealed to the physical analogies between electromagnetism and hydrodynamics in their development of these theories. I argue that a closer historical examination of the different (...) ways in which Maxwell and Helmholtz each deployed this analogy gives further insight into debates about the representational and explanatory power of mathematical models.

: An examination of two thought experiments in contemporary physics reveals that the same thought experiment can be reanalyzed from the perspective of different and incompatible theories. This fact undermines those accounts of thought experiments that claim their justificatory power comes from their ability to reveal the laws of nature. While thought experiments do play a genuine evaluative role in science, they do so by testing the nonempirical virtues of a theory, such as consistency and explanatory power. I conclude that, (...) while their interpretation presupposes a whole set of background theories and putative laws, thought experiments nonetheless can evolve and be retooled for different theories and ends.

Pornographic speech harms women by playing a key role in sustaining the social conditions through which women's liberty and equality are undercut. Though there is a principled moral and constitutional basis for pursuing a legal strategy in fighting pornography, we should not overestimate the effectiveness of the law or underestimate its potential dangers. The struggle against pornography must be waged through education, expressive exploration, and protest, not through the law.

The etiology of Tauopathies, a diverse class of neurodegenerative diseases associated with the Microtubule Associated Protein (MAP) Tau, is usually described by a common mechanism in which Tau dysfunction results in the loss of axonal microtubule stability. Here, we reexamine and build upon the canonical disease model to encompass other Tau functions. In addition to regulating microtubule dynamics, Tau acts as a modulator of motor proteins, a signaling hub, and a scaffolding protein. This diverse array of functions is related to (...) the dynamic nature of Tau isoform expression, post‐translational modification (PTM), and conformational flexibility. Thus, there is no single mechanism that can describe Tau dysfunction. The effects of specific pathogenic mutations or aberrant PTMs need to be examined on all of the various functions of Tau in order to understand the unique etiology of each disease state. (shrink)

The United Nations (UN), facing increasingly intense challenges in the fulfillment of its mission, also harbors the potential for enhanced effectiveness, relevance, and legitimacy in the form of the human rights-based approach. The human rights-based approach (HRBA) is one model for translating the organization’s values into a more adaptive, inclusive, dynamic, and responsive system of processes and outcomes. In the arena of politics, its meeting with a meaningful degree of receptiveness could signal a growing acceptance of the validity of structural (...) approaches to development and other issues despite traditional defensive positions on human rights. Application of the HRBA in programming is leading to greater appreciation for addressing core disparities and promoting empowerment for sustainable outcomes. It is also cultivating new qualities in development practitioners, advancing creativity, openness and responsiveness in organizational culture. In feeding its evolution in this way, the UN as a system has the potential for deeper, longer-term mission fulfillment and thus ensuring its viability. (shrink)

We can think about ourselves in a variety of ways, but only some of the thoughts that we entertain about ourselves will be thoughts which we know concern ourselves. I call these first-person thoughts, and the component of such thoughts that picks out the object about which one is thinking—oneself—the self-concept. In this thesis I am concerned with providing an account of the content of the self-concept. The challenge is to provide an account that meets two conditions on first-person thought. (...) The account must show how we are aware of ourselves when we entertain first-person thoughts, so that we have an account that establishes the cognitive significance of first-person thoughts. But, in addition, this awareness must be as robust as the thinker’s ability to entertain first-person thoughts if our account is to respect the guaranteed referential success of the self-concept. I introduce both the subject matter of the thesis, and the constraints on a satisfactory account of that subject matter in the first chapter. In the second chapter I then set up a further problem: much of our self-knowledge is knowledge of our current mental states and it is often argued that we know about and can ascribe those mental states on the basis of introspection alone. The first constraint on an account of first-person thought described in the preceding paragraph requires that we be aware of ourselves in some way if our thoughts are to have the special cognitive significance of first-person thoughts. Yet, I argue, we neither do nor can introspectively observe a subject of thought and experience when we come to know about our mental states and experiences. The failure of introspection to supply us with perceptual information about a subject of thought presents us with the further potential problem. According to Fregean semantics sense determines reference: we count on the content of the elements of thought to determine the reference of terms that are used to express those elements. If we do not introspectively observe a subject of thought then we seem to be at a loss to account for the concept and we are at risk of having to accept that neither the self-concept nor the first-person pronoun are referential. In the remainder of my thesis I consider various responses that we can offer to this problem. First, I examine whether we can avoid the problem with an alternative account of first-person reference according to which reference is fixed by a reflexive rule, and whether we can also base an account of first-person thought on this account of first-person reference. Secondly, I look at the descriptivist view of first-person thought which could potentially provide both an account of first-person thought and first-person reference. These two suggestions must be rejected on the grounds that they fail to accommodate the special cognitive significance of first-person thought. A third approach to first-person thought argues that we employ an objective self-concept when we think about ourselves, a concept that is informed by bodily experience, rather than by introspective observation of a subject. Yet such an account cannot make sense of first-person thoughts in which we question our own embodiment. Lastly I consider whether it is possible to explain the cognitive significance of first-person thought in terms of non-conceptual first-person contents. (shrink)

The Bayesian model of multisensory cue integration proposed by Ernst and Banks provides an attractive model for understanding a way that our sensory systems may interact. Moreover, it has been suggested that the process of multisensory integration that it models underpins conscious experiences with multisensory representational contents merged across modalities. Should we therefore take empirical support for the Bayesian model as evidence of the multimodality of perception? Focusing on evidence of integration across vision and touch, I argue that apparent support (...) for the model does not warrant the rejection of the view that each of our conscious perceptual experiences is associated with one and only one sense modality.

It has frequently been suggested that quantum mechanics may provide a genuine case of ontic vagueness or metaphysical indeterminacy. However, discussions of quantum theory in the vagueness literature are often cursory and, as I shall argue, have in some respects been misguided. Hitherto much of the debate over ontic vagueness and quantum theory has centered on the “indeterminate identity” construal of ontic vagueness, and whether the quantum phenomenon of entanglement produces particles whose identity is indeterminate. I argue that this way (...) of framing the debate is mistaken. A more thorough examination of quantum theory and the phenomenon of entanglement reveals that quantum mechanics is best interpreted as supporting what I call the “vague property” construal of ontic vagueness, where vague properties are understood in terms of determinable properties without the corresponding determinates.

This essay critically assesses two strategies of accommodation used by defenders of impartialism in ethics to argue that the care orientation represents no genuine challenge to impartialist theoretical paradigms. One strategy focuses on impartiality as a constraint on moral deliberation, the other as a constraint on moral justification.

The ontic conception of explanation, according to which explanations are "full-bodied things in the world," is fundamentally misguided. I argue instead for what I call the eikonic conception, according to which explanations are the product of an epistemic activity involving representations of the phenomena to be explained. What is explained in the first instance is a particular conceptualization of the explanandum phenomenon, contextualized within a given research program or explanatory project. I conclude that this eikonic conception has a number of (...) benefits, including making better sense of scientific practice and allowing for the full range of normative constraints on explanation.

The 2006 decision by the International Astronomical Union to strip Pluto of its status as a planet generated considerable uproar not only in scientific circles, but among the lay public as well. After all, how can a vote by 424 scientists in a conference room in Prague undermine what every well-educated second grader knows is a scientific fact? The Pluto controversy provides a new and fertile ground in which to revisit the traditional philosophical problems of natural kinds and scientific change. (...) Before engaging these philosophical problems, however, there are two misguided reactions to the Pluto controversy worth dispelling from the start. The first misguided reaction is that this sort of classificatory .. (shrink)

Narratives of artificial intelligence frame public perceptions and expectations, and have a performative role, potentially leading to increased attention and resource allocation, acceptance of AI, or resistance to the technology. However, research on AI narratives frequently produces generalized and decontextualized accounts. This paper argues for closer examination of the specific processes that shape AI narratives in particular contexts. To explore this, nine AI-related exhibitions held in German museums from 2022 to 2023 were analyzed. The study draws on interviews with curatorial (...) teams and exhibition materials to investigate what narratives of AI museums are formed and how those relate to the dominant AI narratives described in previous research. It is shown that curators are critical of dominant AI narratives and aim to deconstruct common myths and present more nuanced portrayals of AI. Yet, they also face challenges in balancing this critical stance with the need for creating engaging, accessible exhibitions. The analysis reveals that while some curatorial strategies successfully counter AI stereotypes, others fail or inadvertently reproduce mainstream imaginaries. Curators discover that avoiding problematic understandings of AI in the way they had initially intended is challenging or even impossible. In other cases, when elements of mainstream AI discourse resurface in museum exhibits despite the critical stance of the curators, they remain unexamined, or are regarded as insignificant and inconsequential.

We introduce what we call the Emergent Model of forgiving, which is a process-based relational model conceptualizing forgiving as moral and normative repair in the wake of grave wrongs. In cases of grave wrongs, which shatter the victim’s life, the Classical Model of transactional forgiveness falls short of illuminating how genuine forgiveness can be achieved. In a climate of persistent threat and distrust, expressions of remorse, rituals and gestures of apology, and acts of reparation are unable to secure the moral (...) confidence and trust required for moral repair, much less for forgiveness. Without the rudiments of a shared moral world — a world in which, at the very least, the survivor’s violation can be collectively recognized as a violation, and her moral status and authority collectively acknowledged and respected — expressions of remorse, gestures and rituals of apology, or promises of compensation have no authority as meaningful communicative acts with reparative significance. Accordingly, we argue that repair in the wake of traumatic violence involves ‘world-building,’ which supports the ability of survivors to move from despair to hope, from radical and disabling distrust to trust and engagement, and thus from impotence to effective agency. Our Emergent Model treats forgiveness as a slowly developing outcome of a series of changes in a person’s relationship to the trauma and its aftermath, in which moral agency is regained. We argue that forgiveness after grave wrongs and world-shattering harm, when it occurs, emerges from other phenomena, such as cohabitation within a community, gestures of reconciliation, working on shared projects, the developing of trust. On this view, forgiveness is an emergent phenomenon; it entails taking and exercising normative power—coming to claim one’s own moral authority in relation to oneself, one’s assailant, and one’s community. The processes that ultimately constitute forgiving are part and parcel of normative repair more broadly construed. (shrink)

In her groundbreaking volume Anaesthetics of Existence: Essays on Experience at the Edge, Cressida Heyes provokes readers with the question, “How might experience not only motivate politics but also itself act as a medium of political change?” This essay builds on Heyes’s provocation by exploring self-making and self-advocacy within carceral political economies. Engaging Heyes’s discussion of “normative temporality,” I consider unstable subjectivities and a black feminist formation of “revelatory agency” to contend that the carceral consumption of human life-time expands, complicates, (...) or radically shifts the scope of the political.

Simulations using idealized numerical models can often generate behaviors or patterns that are visually very similar to the natural phenomenon being investigated and to be explained. The question arises, when should these model simulations be taken to provide an explanation for why the natural phenomena exhibit the patterns that they do? An important distinction for answering this question is that between ‘how-possibly’ explanations and ‘how-actually’ explanations. Despite the importance of this distinction there has been surprisingly little agreement over how exactly (...) this distinction should bedrawn. I shall argue that inadequate attention has been paid to the different contexts in which an explanation can be given and the different levels of abstraction at which the explanandum phenomenon can be framed. By tracing how scientists are using model simulations to explain a striking periodic banding of vegetation known as tiger bush, I will show how our understanding of the distinction between how-possibly and how-actually model explanations needs to be revised.

: Although Dirac rarely participated in the interpretational debates over quantum theory, it is traditionally assumed that his views were aligned with Heisenberg and Bohr in the so-called Copenhagen-Göttingen camp. However, an unpublished—and apparently unknown—lecture of Dirac's reveals that this view is mistaken; in the famous debate between Einstein and Bohr, Dirac sided with Einstein. Surprisingly, Dirac believed that quantum mechanics was not complete, that the uncertainty principle would not survive in the future physics, and that a deterministic description of (...) the microworld would be recovered. In this paper I show how we can make sense of this unpublished lecture in the context of Dirac's broader philosophy of quantum mechanics, and how our present understanding of Dirac's philosophical views must be revised.

Detailed examinations of scientific practice have revealed that the use of idealized models in the sciences is pervasive. These models play a central role in not only the investigation and prediction of phenomena, but in their received scientific explanations as well. This has led philosophers of science to begin revising the traditional philosophical accounts of scientific explanation in order to make sense of this practice. These new model-based accounts of scientific explanation, however, raise a number of key questions: Can the (...) fictions and falsehoods inherent in the modeling practice do real explanatory work? Do some highly abstract and mathematical models exhibit a noncausal form of scientific explanation? How can one distinguish an exploratory "how-possibly" model explanation from a genuine "how-actually" model explanation? Do modelers face tradeoffs such that a model that is optimized for yielding explanatory insight, for example, might fail to be the most predictively accurate, and vice versa? This chapter explores the various answers that have been given to these questions. (shrink)
