Is change missing in Hamiltonian Einstein–Maxwell theory? Given the most common definition of observables, observables are constants of the motion and nonlocal. Unfortunately this definition also implies that the observables for massive electromagnetism with gauge freedom are inequivalent to those of massive electromagnetism without gauge freedom. The alternative Pons–Salisbury–Sundermeyer definition of observables, aiming for Hamiltonian–Lagrangian equivalence, uses the gauge generator G, a tuned sum of first-class constraints, rather than each first-class constraint separately, and implies equivalent observables for equivalent massive electromagnetisms. (...) For General Relativity, G generates 4-dimensional Lie derivatives for solutions. The Lie derivative compares different space-time points with the same coordinate value in different coordinate systems, like 1 a.m. summer time versus 1 a.m. standard time, so a vanishing Lie derivative implies constancy rather than covariance. Requiring equivalent observables for equivalent formulations of massive gravity confirms that G must generate the 4-dimensional Lie derivative for observables. These separate results indicate that observables are invariant under internal gauge symmetries but covariant under external gauge symmetries, but can this bifurcated definition work for mixed theories such as Einstein–Maxwell theory? Pons, Salisbury and Shepley have studied G for Einstein–Yang–Mills. For Einstein–Maxwell, both \ and \ are invariant under electromagnetic gauge transformations and covariant under 4-dimensional coordinate transformations. Using the bifurcated definition, these quantities count as observables, as one would expect on non-Hamiltonian grounds. (shrink)

A primary criterion on which models of cognition are evaluated is their ability to fit empirical data. To understand the reason why a model yields a good or poor fit, it is necessary to determine the data‐fitting potential (i.e., flexibility) of the model. In the first part of this article, methods for comparing models and studying their flexibility are reviewed, with a focus on parameter space partitioning (PSP), a general‐purpose method for analyzing and comparing all classes of cognitive models. PSP (...) is then demonstrated in the second part of the article in which two connectionist models of speech perception (TRACE and ARTphone) are compared to learn how design differences affect model flexibility.

James L. Anderson analyzed the novelty of Einstein's theory of gravity as its lack of "absolute objects." Michael Friedman's related work has been criticized by Roger Jones and Robert Geroch for implausibly admitting as absolute the timelike 4-velocity field of dust in cosmological models in Einstein's theory. Using the Rosen-Sorkin Lagrange multiplier trick, I complete Anna Maidens's argument that the problem is not solved by prohibiting variation of absolute objects in an action principle. Recalling Anderson's proscription of "irrelevant" variables, (...) I generalize that proscription to locally irrelevant variables that do no work in some places in some models. This move vindicates Friedman's intuitions and removes the Jones-Geroch counterexample: some regions of some models of gravity with dust are dust-free and so naturally lack a timelike 4-velocity, so diffeomorphic equivalence to is spoiled. Torretti's example involving constant curvature spaces is shown to have an absolute object on Anderson's analysis, viz., the conformal spatial metric density. The previously neglected threat of an absolute object from an orthonormal tetrad used for coupling spinors to gravity appears resolvable by eliminating irrelevant fields. However, given Anderson's definition, GTR itself has an absolute object : a change of variables to a conformal metric density and a scalar density shows that the latter is absolute. (shrink)

It has become almost commonplace to claim that utilitarianism was, from its inception, an imperialist theory. Many writers, from Bentham’s own followers to recent scholars, have suggested that from Bentham onward, utilitarians reveled in the opportunity that they believed despotic power provided for the establishment of perfectly rational laws and institutions. A closer look at Bentham’s own views on empire, however, reveals a sharp break between his position on European colonies and that of followers such as James and John (...) Stuart Mill. For Bentham, the utilitarian doctrine led to criticisms of the empires of his day. Bentham is better understood as a participant in the late-eighteenth-century skepticism about imperial conquests and aspirations than he is as a proto-colonialist or a “Solon” of India. Once he is understood in this light, our picture of his successors, especially J. S. Mill, is revised as well. (shrink)

James L. Anderson analyzed the conceptual novelty of Einstein's theory of gravity as its lack of ``absolute objects.'' Michael Friedman's related concept of absolute objects has been criticized by Roger Jones and Robert Geroch for implausibly admitting as absolute the timelike 4-velocity field of dust in cosmological models in Einstein's theory. Using Nathan Rosen's action principle, I complete Anna Maidens's argument that the Jones-Geroch problem is not solved by requiring that absolute objects not be varied. Recalling Anderson's proscription of (...) (globally) ``irrelevant'' variables that do no work (anywhere in any model), I generalize that proscription to locally irrelevant variables that do no work in some places in some models. This move vindicates Friedman's intuitions and removes the Jones-Geroch counterexample: some regions of some models of gravity with dust are dust-free, and there is no good reason to have a timelike dust 4-velocity vector there. Eliminating the irrelevant timelike vctors keeps the dust 4-velocity from counting as absolute by spoiling its neighborhood-by-neighborhood diffeomorphic equivalence to (1,0,0,0). A more fundamental Gerochian timelike vector field presents itself in gravity with spinors in the standard orthonormal tetrad formalism, though eliminating irrelevant fields might solve this problem as well.

The question of when and how bottom‐up input is integrated with top‐down knowledge has been debated extensively within cognition and perception, and particularly within language processing. A long running debate about the architecture of the spoken‐word recognition system has centered on the locus of lexical effects on phonemic processing: does lexical knowledge influence phoneme perception through feedback, or post‐perceptually in a purely feedforward system? Elman and McClelland (1988) reported that lexically restored ambiguous phonemes influenced the perception of the following phoneme, (...) supporting models with feedback from lexical to phonemic representations. Subsequently, several authors have argued that these results can be fully accounted for by diphone transitional probabilities in a feedforward system (Cairns et al., 1995; Pitt & McQueen, 1998). We report results strongly favoring the original lexical feedback explanation: lexical effects were present even when transitional probability biases were opposite to those of lexical biases.

The classical utilitarian legacy of Jeremy Bentham, J. S. Mill, James Mill, and Henry Sidgwick has often been charged with both theoretical and practical complicity in the growth of British imperialism and the emerging racialist discourse of the nineteenth century. But there has been little scholarly work devoted to bringing together the conflicting interpretive perspectives on this legacy and its complex evolution with respect to orientalism and imperialism. This volume, with contributions by leading scholars in the field, represents the (...) first attempt to survey the full range of current scholarly controversy on how the classical utilitarians conceived of 'race' and the part it played in their ethical and political programs, particularly with respect to such issues as slavery and the governance of India. The book both advances our understanding of the history of utilitarianism and imperialism and promotes the scholarly debate, clarifying the major points at issue between those sympathetic to the utilitarian legacy and those critical of it.

The essays in this volume grew out of a seminar examining the possibility of the emergence of a new consensus in the philosophy of science. While that issue is not resolved, we are presented with the most thorough examination of problems associated with the deductive-nomological model of explanation and its variants since the publication of Hempel's Aspects of Scientific Explanation and other Essays in the Philosophy of Science. The discussion begins with Wesley Salmon's monograph-length review of the past forty years (...) of work in the tradition initiated by Hempel and Oppenheim in their groundbreaking article "Studies in the Logic of Explanation". As one of the major players in the debates, Salmon's personal account is informative; it provides a useful introduction to the topic and covers the recent history of work on explanation in a manner that allows the uninitiated to follow the arguments and intricacies of the essays that follow. A main theme in Salmon's essay, as in much of his work, is the relation between the theory of explanation and the concept of causation. Given that the notion of causal laws plays a dominant role in DN explanations, this discussion is most welcome. Causation is also a clear concern of many of the other papers. The resolution of some of the tensions between Salmon's approach to causation, and the various roles of explanation in the philosophy of science, is, in fact, one of the main objectives of the extended concluding piece by Philip Kitcher. For Kitcher, explanations serve as unifying mechanisms for theories within different disciplines. Unification in turn also serves as a criterion for choosing between competing theories. The interplay between, on the one hand, Salmon's attention to the problems deriving from Hempel's initial formulation of DN and, on the other hand, Kitcher's concerns with Salmon's conceptualization of causation, produces one of the more fascinating dialectics of the volume. By attending to their dialogue, we see just how far the theory of explanation has come in the last forty years and yet how slow progress can be when fundamental problems are deeply entrenched. Causation continues to bedevil us. With one exception, the remaining contributors to this volume seem to confirm that judgment. Matti Sintonen, Paul Humphreys, David Papineau, Nancy Cartwright, James Woodward, and Merilee Salmon explore the many facets of causation as it applies to clarifying our explanatory objectives. Peter Railton is an exception. In his paper Railton reminds us that behind the epistemological and pragmatic concerns of most of the other contributors, Wesley Salmon included, there lies a set of metaphysical concerns. A thorough analysis of causation and, hence, a resolution to many of the DN model's problems requires a logically prior assessment of the relation between the epistemology of causation and the metaphysics of necessity. How one decides that issue or cluster of issues, Railton reminds us, will play heavily in the controversies between realists and nonrealists over the proper use of the principle of inference to the best explanation.

Andrea Pitts’ Anzaldúan reading of multiplicitous agency critically weaves together Latinx, Latina feminist, Black, Indigenous, queer and trans, and disability theorizing alongside Anzaldúan scholarship to demonstrate how pluralistic communities come together for positive social transformation. In this process, they provide a powerful scholarly resource to Anzaldúan scholarship. Ultimately, Pitts invites us to break away from modes of being that fall into individualism, insularities, binaries, isolation, and even imperialism to imagine instead “new geographies of selves” (32). This revision involves (...) developing an agential capacity that recognizes ours and other’s (nos y otrxs) multiplicitous and complex identities and their interaction. By being open to this complexity, opacity, ambivalence, and the imperative to new ways of being both intangible and tangible radical transformations emerge in practice. However, though rooted in Leonard Harris’ insurrectionist ethics, Pitts recognizes one must leave room for a coalitional process that may not succeed but is always open to interpretation and challenge considering the fluidity of multiplicitous agency that informs it (166).

The Quality of Thought develops and defends the thesis that thinking is a kind of experience, characterized by a sui generis (“cognitive”) phenomenology, determinates of which are thought contents—what I call the phenomenal intentionality of thought thesis. It draws out the implications of this thesis for issues in philosophy of mind, philosophy of language and metaphysics. The view defended is radically internalist and intensionalist, and thus goes against received doctrines in philosophy of mind (externalism) and language (extensionalism). It also advocates (...) for a metaphysically neutral, non-naturalistic approach to the philosophical study of mind—what I call “Analytic Phenomenology”—in combination with agnosticism about the nature of the relationship between consciousness and physical reality. -/- The book identifies persistent problems with Dretske-inspired causal-informational-teleological theories of conceptual content, and diagnoses them as due to leaving out what it’s like to think a thought—to entertain or grasp a propositional (conceptual) content. It is thus a contribution to the increasingly influential Phenomenal Intentionality Research Program. It includes refutations of classic externalism (Putnam and Burge) and arguments that standard motivations for direct reference theories of names (Kripke), indexicals and demonstratives (Kaplan) are not inevitable, and alternative accounts of their (and their conceptual equivalents’) semantics. It also addresses outstanding challenges to the phenomenal intentionalist view of thought content, including the existence of unconscious thought, the elusiveness of conceptual phenomenology, the matching content problem, phenomenal compositionality, and the determination of conceptual reference.

Philosophers have long endeavored to support politically relevant efforts, including institutional and legal reforms, insurrectionist uprisings, anticolonial independence struggles, cultural movements, and anti‐violence work. While some debates have emerged regarding normative questions of whether or how philosophers should be activists, this chapter focuses more directly on the manner in which philosophical authors have supported, engaged in, or examined forms of political participation that seek to end forms of oppression such as racism, sexism, colonialism, and systemic poverty. It distinguishes between philosophers (...) who are writing about or in support of forms of political activism and social movements. The chapter explores specific activists and movements that have become relevant within academic philosophy. It examines philosophers who have engaged in direct political action while working within academic philosophy. (shrink)

This volume brings together many prominent philosophical voices today focusing on issues of U. S. Latinx and Latin American identities and feminist theory. As such, the essays collected here highlight the varied and multidimensional aspects of gender, racial, cultural, and sexual questions impacting U.S. Latinx and Latin American communities today. The collection also highlights a number of important threads of analysis from fields as diverse as disability studies,aesthetics, literary theory, and pop culture studies.

Structural realism is considered by many realists and antirealists alike as the most defensible form of scientific realism. There are now many forms of structural realism and an extensive literature about them. There are interesting connections with debates in metaphysics, philosophy of physics and philosophy of mathematics. This entry is intended to be a comprehensive survey of the field.

Feminists today are re-imagining nature, biology, and matter in feminist thought and critically addressing new developments in biology, physics, neuroscience, epigenetics and other scientific disciplines. Mattering, edited by noted feminist scholar Victoria Pitts-Taylor, presents contemporary feminist perspectives on the materialist or ‘naturalizing’ turn in feminist theory, and also represents the newest wave of feminist engagement with science. The volume addresses the relationship between human corporeality and subjectivity, questions and redefines the boundaries of human/non-human and nature/culture, elaborates on the entanglements (...) of matter, knowledge, and practice, and addresses biological materialization as a complex and open process. This volume insists that feminist theory can take matter and biology seriously while also accounting for power, taking materialism as a point of departure to rethink key feminist issues. The contributors, an international group of feminist theorists, scientists and scholars, apply concepts in contemporary materialist feminism to examine an array of topics in science, biotechnology, biopolitics, and bioethics. These include neuralplasticity and the brain-machine interface; the use of biometrical identification technologies for transnational border control; epigenetics and the intergenerational transmission of the health effects of social stigma; ADHD and neuropharmacology; and randomized controlled trials of HIV drugs.A unique and interdisciplinary collection, Mattering presents in grounded, concrete terms the need for rethinking disciplinary boundaries and research methodologies in light of the shifts in feminist theorizing and transformations in the sciences.

Because of the “all-or-none” character of nervous activity, neural events and the relations among them can be treated by means of propositional logic. It is found that the behavior of every net can be described in these terms, with the addition of more complicated logical means for nets containing circles; and that for any logical expression satisfying certain conditions, one can find a net behaving in the fashion it describes. It is shown that many particular choices among possible neurophysiological assumptions (...) are equivalent, in the sense that for every net behaving under one assumption, there exists another net which behaves under the other and gives the same results, although perhaps not in the same time. Various applications of the calculus are discussed. (shrink)

Moral philosophy is the study of what morality is and what it requires of us. As Socrates said, it's about "how we ought to live"-and why. It would be helpful if we could begin with a simple, uncontroversial definition of what morality is. Unfortunately, we cannot. There are many rival theories, each expounding a different conception of what it means to live morally, and any definition that goes beyond Socrates's simple formula-tion is bound to offend at least one of them. (...) This should make us cautious, but it need not paralyze us. In this chapter, I will describe the "minimum conception" of morality. (shrink)

It is a commonplace in the philosophy of physics that any local physical theory can be represented using arbitrary coordinates, simply by using tensor calculus. On the other hand, the physics literature often claims that spinors \emph{as such} cannot be represented in coordinates in a curved space-time. These commonplaces are inconsistent. What general covariance means for theories with fermions, such as electrons, is thus unclear. In fact both commonplaces are wrong. Though it is not widely known, Ogievetsky and Polubarinov constructed (...) spinors in coordinates in 1965, enhancing the unity of physics and helping to spawn particle physicists' concept of nonlinear group representations. Roughly and locally, these spinors resemble the orthonormal basis or "tetrad" formalism in the symmetric gauge, but they are conceptually self-sufficient and more economical. The typical tetrad formalism is de-Ockhamized, with six extra field components and six compensating gauge symmetries to cancel them out. The Ogievetsky-Polubarinov formalism, by contrast, is Ockhamized, with most of the fluff removed. As developed nonperturbatively by Bilyalov, it admits any coordinates at a point, but "time" must be listed first. Here "time" is defined in terms of an eigenvalue problem involving the metric components and the matrix $diag$, the product of which must have no negative eigenvalues in order to yield a real symmetric square root that is a function of the metric. Thus even formal general covariance requires reconsideration; the atlas of admissible coordinate charts should be sensitive to the types and \emph{values} of the fields involved. Apart from coordinate order and the usual spinorial two-valuedness, Ogievetsky-Polubarinov spinors form, with the metric, a nonlinear geometric object, for which important results on Lie and covariant differentiation are recalled. Such spinors avoid a spurious absolute object in the Anderson-Friedman analysis of substantive general covariance. They also permit the gauge-invariant localization of the infinite-component gravitational energy in General Relativity. Density-weighted spinors exploit the conformal invariance of the massless Dirac equation to show that the volume element is absent. Thus instead of an arbitrary nonsingular matrix with 16 components, 6 of which are gauged away by a new local $O$ gauge group and one of which is irrelevant due to conformal covariance, one can, and presumably should, use density-weighted Ogievetsky-Polubarinov spinors coupled to the 9-component symmetric square root of the part of the metric that fixes null cones. Thus $\frac{7}{16}$ of the orthonormal basis is eliminated as surplus structure. Greater unity between spinors and tensors and the like is achieved, such as regarding conservation laws. Regarding the conventionality of simultaneity, an unusually wide range of $\epsilon$ values is admissible, but some extreme values are inadmissible. Standard simultaneity uniquely makes the spinor transformation law linear and independent of the metric, because transformations among the standard Cartesian coordinate systems fall within the conformal group, for which the spinor transformation law is linear. The surprising mildness of the restrictions on coordinate order as applied to the Schwarzschild solution is exhibited. (shrink)

"The lectures that follow were delivered at the Lowell Institute in Boston in November and December, 1906, and in January, 1907, at Columbia University, in New York."-Preface, pg. 3.

For this 1897 publication, the American philosopher William James brought together ten essays, some of which were originally talks given to Ivy League societies. Accessible to a broader audience, these non-technical essays illustrate the author's pragmatic approach to belief and morality, arguing for faith and action in spite of uncertainty. James thought his audiences suffered 'paralysis of their native capacity for faith' while awaiting scientific grounds for belief. His response consisted in an attitude of 'radical empiricism', which deals (...) practically rather than ideologically with real-world phenomena. When facing a 'momentous' decision about belief, he says, we both can and must choose the best hypothesis. The first four essays apply this principle to religious faith, and the rest explore the pragmatic approach to such topics as determinism, ethics and individual achievement. James developed his ideas further in The Varieties of Religious Experience and Pragmatism, both of which are reissued in this series. (shrink)

The Gifford Lectures were established in 1885 at the universities of St Andrews, Glasgow, Aberdeen and Edinburgh to promote the discussion of 'Natural Theology in the widest sense of the term - in other words, the knowledge of God', and some of the world's most influential thinkers have delivered them. The 1901–2 lectures given in Edinburgh by American philosopher William James are considered by many to be the greatest in the series. The lectures were published in book form in (...) 1902 and have been reprinted many times. James, who was educated in the United States and Europe, and spent much of his career teaching philosophy at Harvard, was very influential in the development of modern psychology, and in these twenty lectures he explores the personal experience of religion. Some of the topics include religion and neurology, 'the sick soul', saintliness, and mysticism. (shrink)
