Standard lore holds that magnetic forces are incapable of doing mechanical work. More precisely, the claim is that whenever it appears that a magnetic force is doing work, the work is actually being done by another force, with the magnetic force serving only as an indirect mediator. However, the most familiar instances of magnetic forces acting in everyday life, such as when bar magnets lift other bar magnets, appear to present manifest evidence of magnetic forces doing work. These sorts of (...) counterexamples are often dismissed as arising from quantum effects that lie outside the classical regime. In this paper, we show that quantum theory is not needed to account for these phenomena, and that classical electromagnetism admits a model of elementary magnetic dipoles on which magnetic forces can indeed do work. In order to develop this model, we revisit the foundational principles of the classical theory of electromagnetism, showcase the importance of constraints from relativity, examine the structure of the multipole expansion, and study the connection between the Lorentz force law and conservation of energy and momentum. (shrink)

We address a long-standing debate over whether classical magnetic forces can do work, ultimately answering the question in the affirmative. In detail, we couple a classical particle with intrinsic spin and elementary dipole moments to the electromagnetic field, derive the appropriate generalization of the Lorentz force law, show that the particle's dipole moments must be collinear with its spin axis, and argue that the magnetic field does mechanical work on the particle's elementary magnetic dipole moment. As consistency checks, (...) we calculate the overall system's energy-momentum and angular momentum, and show that their local conservation equations lead to the same force law and therefore the same conclusions about magnetic forces and work. We also compute the system's Belinfante-Rosenfeld energy-momentum tensor. (shrink)

We describe a new experiment to measure the gravitomagnetic field of the Earth. This field, a consequence of the general relativistic formulation of Mach's principle (WEM—Wheeler-Einstein-Mach principle), has never been detected. The idea is to measure the Lense-Thirring precession of the nodal lines of two laser-ranged satellites with supplementary inclinations. In this way it is possible to separate the relativistic nodal precession from the classical nodal precession due to the multipole moments of the Earth.

In the United States, it is common for people entering christian organizations to receive explanation of what the Bible means before being handed the book and asked to read. Religious ideological transfer stems from this strict codification, and the Story of Abraham highlights the effective blending between original text and interpretation. Recognizing how the Story of Abraham calls for, as Kierkegaard suggested, a suspension of the ethical for obedience, it justifies entrance into a religious state of exception, a fully subjective (...) moment into which the sole sovereign of “divine will” is the self. The social ramifications, beyond a-logical relativism, involve the historic and continued justification of religious otherization and dehumanization, shrined in a belief of divinity. In contemporary debate, the religious hunker down, entrenching themselves within their ideology, while many in deconstructivist camps want to tear these institutions apart. I suggest a middle-ground: a radical reinterpretation — through philosophical, linguistic and literary theory methods — of the Story of Abraham as a narrative reflecting the Tower of Babel motif, to work within the christian ideological system to create strategic biblical interpretations for positive social effect.

By decomposing the charge-current density, it is demonstrated that the “built-in” spin magnetic moment of a free relativistic electron iseħ/2mc, wherem is the Lorentz mass.

In this work, a neo-classical relativistic mechanics theory is presented where the spin of an electron is an inherent part of its world space-time path as a point particle. The fourth-order equation of motion corresponds to the same covariant Lagrangian function in proper time as in special relativity except for an additional spin energy term. The theory provides a hidden-variable model of the electron where the dynamic variables give a complete description of its motion, giving a classical mechanics explanation (...) of the electron’s spin, its dipole moments, and Schrödinger’s zitterbewegung, These features are also described mathematically by quantum mechanics theory, of course, but without any physical picture of an underlying reality. The total motion of the electron can be decomposed into a sum of a local spin motion about a point and a global motion of this point, called here the spin center. The global motion is sub-luminal and described by Newton’s Second Law in proper time, the time for a clock fixed at the spin center, while the total motion occurs at the speed of light c, consistent with the eigenvalues of Dirac’s velocity operators having magnitude c. The local spin motion is an inherent perpetual motion, which for a free electron is periodic at the ultra-high zitterbewegung frequency and its path is circular in a spin-center reference frame. In an electro-magnetic field, this spin motion generates magnetic and electric dipole energies through the Lorentz force on the electron’s point charge. The electric dipole energy corresponds to the spin-orbit coupling term involving the electric field that appears in the corrected Pauli non-relativistic Hamiltonian, which has long been used to explain the doublet structure of the spectral lines of the excited hydrogen atom. Pauli’s spin-orbit term is usually derived, however, from his magnetic dipole energy term, including also the effect of Thomas precession, which halves this energy. The magnetic dipole energy from Pauli’s and Dirac’s theory is twice that in the neo-classical theory, a discrepancy that has not been resolved. By defining a spin tensor as the angular momentum of the electron’s total motion about its spin center, the fundamental equations of motion can be re-written in an identical form to those of the Barut–Zanghi electron theory. This allows the equations of motion to be expressed in an equivalent form involving operators applied to a state function of proper time satisfying a neo-classical Dirac–Schrödinger spinor equation. This state function produces the dynamic variables from the same operators as in Dirac’s theory for the electron but without any probability implications. It leads to a neo-classical wave function that satisfies Dirac’s relativistic wave equation for the free electron by applying the Lorentz transformation to express proper time in the state function in terms of an observer’s space-time coordinates, showing that there is a close connection between the neo-classical theory and quantum mechanics theory for the electron’s dynamics.

Within the context of Barut's self-field approach to quantum electrodynamics, we show that the exact relativistic expression for the Einstein A-coefficient of atomic spontaneous emission reduces, in the long wavelength approximation, to a form containing electric- and magnetic-like multipole contributions related to the transition charge and current distributions of the relativistic electron. A number of interesting features of the expressions involved are discussed, and their generalization to interacting composite systems is also pointed out.

Moral relativism is the doctrine that morality may vary from culture to culture. Given the difficulty of saying when two individuals belong to the same culture it can be taken in more or less radical forms. In its least radical form it means nothing more than that, although morality is fixed and universal for human beings, Martian morality may be different. In its most radical form it implies that each person has his own morality which may vary from one individual (...) to another and from one moment to the next. (shrink)

It was shown in Dirac A117, 610; A118, 351, 1928) that the ultra-violet divergence in quantum electrodynamics is caused by a violation of the time-energy uncertainly relationship, due to the implicit assumption of infinitesimal time information. In Wheeler et al. it was shown that Einstein’s special theory of relativity and Maxwell’s field theory have mathematically equivalent dual versions. The dual versions arise from an identity relating observer time to proper time as a contact transformation on configuration space, which leaves phase (...) space invariant. The special theory has a dual version in the sense that, for any set of n particles, every observer has two unique sets of global variables \\) and \\) to describe the dynamics, where \ is the canonical center of mass. In the \\) variables, time is relative and the speed of light is unique, while in the \\) variables, time is unique and the speed of light is relative with no upper bound. In the Maxwell case, the two sets of particle wave equations are not equivalent. The dual version contains an additional longitudinal radiation term that appears instantaneously with acceleration, leading to the prediction that radiation from a cyclotron will not produce photoelectrons. A major outcome is the dual unification of Newtonian mechanics and classical electrodynamics with Einstein’s special theory of relativity, without the need for point particles, without a self-energy divergency and, without need for the problematic Lorentz–Dirac equation. The purpose of this paper is to introduce the dual theory of relativistic quantum mechanics. In our approach, we obtain three distinct dual relativistic wave equations that reduce to the Schrödinger equation when minimal coupling is turned off. We show that the dual Dirac equation provides a new formula for the anomalous magnetic moment of a charged particle. We can obtain the exact value for the electron g-factor and phenomenological values for the muon and proton g-factors. (shrink)

In this paper, I introduce a quantifier-pluralist theory of time, temporal quantifier relativism. Temporal quantifier relativism includes a restricted quantifier for every instantaneous moment of time. Though it flies in the face of orthodoxy, it compares favorably to rival theories of time. To demonstrate this, I first develop the basic syntax and semantics of temporal quantifier relativism. I then compare the theory to its rivals on three issues: the passage of time, the analysis of change, and temporal ontology.

Truth, Christopher Norris reminds us, is very much out of fashion at the moment whether at the hands of politicians, media pundits, or purveyors of postmodern wisdom in cultural and literary studies. Across a range of disciplines the idea has taken hold that truth-talk is either redundant or the product of epistemic might. Questions of truth and falsehood are always internal to some specific language-game; history is just another kind of fiction; philosophy is only a kind of writing; law is (...) a wholly rhetorical practice. In _Reclaiming Truth_, Norris critiques these fashionable trends of thought and mounts a specific challenge to cultural relativist doctrines in epistemology, philosophy of science, ethics, and political theory. Norris presents his case in a series of closely argued chapters that take issue with the relativist position. He attempts to rehabilitate the value of truth in philosophy of science by restoring a lost distinction between concept and metaphor and argues that theoretical discourse, so far from being an inconsequential activity, has very real consequences, particularly in ethics and politics. This debate has become skewed, he suggests, through the widespread and typically postmodern idea that truth-claims must always go along with a presumptive or authoritarian bid to silence opposing views. On the contrary, there is nothing as dogmatic—or as silencing—as a relativism that acknowledges no shared truth conditions for valid or responsible discourse. Norris also offers a timely reassessment of several thinkers—Althusser and Derrida among them—whose reception history has been distorted by the vagaries of short-term intellectual fashion. _Reclaiming Truth _will be welcomed by readers concerned with the uses and abuses of theory at a time when such questions are in urgent need of sustained and serious debate.

A fundamentally new understanding of the classical electromagnetic interaction of a point charge and a magnetic dipole moment through order v 2 /c 2 is suggested. This relativistic analysis connects together hidden momentum in magnets, Solem's strange polarization of the classical hydrogen atom, and the Aharonov–Bohm phase shift. First we review the predictions following from the traditional particle-on-a-frictionless-rigid-ring model for a magnetic moment. This model, which is not relativistic to order v 2 /c 2 , does reveal a (...) connection between the electric field of the point charge and hidden momentum in the magnetic moment; however, the electric field back at the point charge due to the Faraday-induced changing magnetic moment is of order 1/c 4 and hence is negligible in a 1/c 2 analysis. Next we use a relativistic magnetic moment model consisting of many superimposed classical hydrogen atoms (and anti-atoms) interacting through the Darwin Lagrangian with an external charge but not with each other. The analysis of Solem regarding the strange polarization of the classical hydrogen atom is seen to give a fundamentally different mechanism for the electric field of the passing charge to change the magnetic moment. The changing magnetic moment leads to an electric force back at the point charge which (i) is of order 1/c 2 , (ii) depends upon the magnetic dipole moment, changing sign with the dipole moment, (iii) is odd in the charge q of the passing charge, and (iv) reverses sign for charges passing on opposite sides of the magnetic moment. Using the insight gained from this relativistic model and the analogy of a point charge outside a conductor, we suggest that a realistic multi-particle magnetic moment involves a changing magnetic moment which keeps the electromagnetic field momentum constant. This means also that the magnetic moment does not allow a significant shift in its internal center of energy. This criterion also implies that the Lorentz forces on the charged particle and on the point charge are equal and opposite and that the center of energy of each moves according to Newton's second law F=Ma where F is exactly the Lorentz force. Finally, we note that the results and suggestion given here are precisely what are needed to explain both the Aharonov–Bohm phase shift and the Aharonov–Casher phase shift as arising from classical electromagnetic forces. Such an explanation reinstates the traditional semiclassical connection between classical and quantum phenomena for magnetic moment systems. (shrink)

Relativistic quantum mechanics has been formulated as a theory of the evolution ofevents in spacetime; the wave functions are square-integrable functions on the four-dimensional spacetime, parametrized by a universal invariant world time τ. The representation of states with spin is induced with a little group that is the subgroup of O(3, 1) leaving invariant a timelike vector nμ; a positive definite invariant scalar product, for which matrix elements of tensor operators are covariant, emerges from this construction. In a previous (...) study a second-order equation was introduced similar to the second-order Dirac equation, based on a quadratic function of two operators which are the self-adjoint parts, in this new scalar product, of γμpμ. It is shown in this paper that one of these operators, in fact the one from which the gyromagnetic moment is obtained, can be used to construct a first-order equation. The corresponding quantum theory is somewhat analogous to Dirac's spinor form; the Hamilton equations appear to describe dynamical degrees of freedom in a spacelike hyperplane orthogonal to nμ (in Dirac's theory the motion appears to be lightlike). It is shown that the integration over nμ required by unitarity results in timelike motion (as in the expectation value of Dirac's α). Explicit forms are obtained for the wave functions and currents for free motion. The general form of the theory is written for the (five-dimensional) pre-Maxwell fields required by gauge invariance.

Christopher Norris DERRIDA AT YALE: THE "DECONSTRUCTIVE MOMENT" IN MODERNIST POETICS IN seven types of ambiguity, William Empson breezily remarked of his critical method that it was "either all nonsense or all very startling and new." The reactions went very much as Empson predicted, with a whole new school of criticism eagerly latching on to the idea of multiple meanings in poetry, while the sober-sided scholars indignantly attacked his wayward "misreadings" and flagrant anachronisms. At present, there is a similar controversy (...) raging around the figure of Jacques Derrida, whose influence on literary critics—mainly the Yale school of Geoffrey Hartman, Harold Bloom and J. Hillis Miller— occupies the forefront of debate in current theoretical exchange. Apart from all the sideshow of polemics, this parallel with Empson is a useful jumping-off point for an approach to Derrida and the implications of his writing. Empson opened up the literary text to a practice of reading which released as many ambiguities, overtones, and hints of recondite meaning as the analyst could reasonably claim to find in it. Reason, or commonsense judgment, still played an arbitrating role, since Empson wanted his readings at least to match something in the credible intention—at whatever "unconscious" level—of the author concerned. Subsequently, Empson has taken issue with the American New Critics on precisely this ground of authorial intention. Where they have dismissed all such considerations as outside the critic's proper interest or competence—treating the text as a "verbal icon," detached from any speculative background of motive or intent—Empson has come out in sturdy defense of "intentionalist" readings, based on available evidence of what the poet was trying to express. In other words, Empson, for all his dazzling inventiveness, held to a notion of the author as (implicitly) a self-possessed creator of meanings, one whose intentions demand critical respect, however broadly that requirement is to be interpreted in practice. Anglo-American criticism 242 Christopher Norris243 has lately been much preoccupied with the question of whether—or exactly how far—an author's original "meaning" can be recovered by close attention to his text. E. D. Hirsch's Validity in Interpretation is a classic if long-winded statement of the conservative view: that the critic's obligation is to come as close as possible to establishing what an author most probably meant in using language as. he did.3 The discipline involved is partly a matter of historical semantics (drawing a limit or "horizon" of possible meanings in context), and partly a matter of interpretative tact and sympathy. Hirsch grounds his argument on the Kantian premise that a text is in some sense the surrogate voice of its author, and that texts must therefore be treated, like people, as ends in themselves, and not means toward the critic's display of self-advertising brilliance. All the same, Hirsch has to acknowledge that authorial intention, as such, is beyond the grasp of this reconstructive program, which offers at best a kind of inferential yardstick for narrowing down the range of semantic potential. The problem which Hirsch never quite gets to grips with, despite his elaborate argumentation, is the fact that texts come across to us always from a distance of time, of experience or culture, which makes their meaning more or less opaque and problematic. The author is not simply there in the text, a self-authenticating "voice" of intent, as Hirsch (in his more sanguine moments) would have us believe. One might expect some such assurance from the homely narrative address of a novelist like Fielding, or the intimate soul-baring style of Wordsworth's poetry. Yet Fielding is as cunning a narrative tactician as any, his "voice" a shifting multitude of ironies and ploys; while Wordsworth manages a complex and selective rhetoric of memory which (as recent critics have shown) by no means communicates the "unmediated vision" of purely personal address. Hirsch yields a hostage to the relativist case by proposing a distinction between "meaning" (that which inheres in the text, and which the critic is duty-bound to preserve), and "significance" (the purely associative values which change with the passage of time and make room for rival or updated interpretations...

Corporate management is torn between either focusing solely on the interests of stockholders or taking into account the interests of a wide spectrum of stakeholders. Of course, there need be no conflict where taking the wider view is also consistent with maximising stockholder wealth. In this paper, we examine the extent to which a conflict actually exists by examining the relationship between a company's positive and negative corporate social responsibility activities and equity performance. In general, we find little evidence to (...) suggest that managers taking a wider stakeholder perspective will jeopardise the interest of its stockholders. However, our findings do suggest that the market is not only influenced by the independent CSR activities, but also the totality of these activities and that the facets that they value do vary over time. It seems that most recently, the market has valued most firms that satisfied minimum requirements in the areas of diversity and environmental protection but were most proactive in the area of employee-relations.

In this paper I explore the relationship between social epistemology and relativism in the context of feminist epistemology. I do this by focusing on one particular branch of feminist epistemology - a branch known as standpoint theory - and investigating the connection between this view and epistemic relativism. I begin by defining both epistemic relativism and standpoint theory, and by briefly recounting the standard way that the connection between these two views is understood. The literature at the moment focuses on (...) an aspect of standpoint theory called the epistemic advantage thesis, and on an aspect of relativism which has been called equality. I then show that the connection between relativism and standpoint theory actually turns on a different aspect of standpoint theory, known as the standpoint thesis, and on an aspect of relativism which has been called non-neutrality. I argue that shifting our attention to these other aspects reveals that standpoint theory is clearly and unavoidably relativist, but that this isn’t a problem - standpoint theory can capture everything that it set out to, even on a relativist understanding of the view.

The democratic surprises of 2016—Brexit and the Trump phenomenon—fueled by “fake news”, both real and imagined, have come to constitute a centrifugal, nationalistic, even tribal moment in politics. Running counter to the shared postwar narrative of increasing internationalism, these events reignited embers of cultural and moral relativism in academia and public discourse dormant since the culture wars of the 1990s and ‘60s. This counternarrative casts doubt on the value of belief in universal human rights, which many in the humanities and (...) social sciences argue have of late been used as instruments of postcolonial oppression. This book essay introduces three texts written before the dawn of the latest “post-truth” era—The Sociology of Human Rights by Mark Frezzo, The Political Sociology of Human Rights by Kate Nash, and Keeping Faith with Human Rights by Linda Hogan—that address moral skepticism of human rights. Along with these authors, the essay briefly treats human rights’ past and prospects, analogizing it to the waves of feminist thought: in international politics, developing nations first desired a seat at the table and repeal of discriminatory laws and practices; when one-nation-one-vote did not result in equal treatment, the persistence of hierarchy helped developing nations awaken to their own evolving national identities and they wished to be recognized as not only equal, but different and unique. The essay recapitulates and amplifies these authors’ argument that the contemporary challenge for all nations, their citizens, and for the human rights community is to deliberatively decide what values unite these identities beyond simple self-determination and extend them toward the goal of a just global whole. The essay also makes an original contribution in summarizing the initial post-war debate in the United Nations that birthed the 1948 Declaration of Human Rights, which has been subject to revisionism and perspectivism typical of cultural and moral relativism. It provides some social scientific, historical, and philosophic grounding for serious conversation of the ideas of truths in politics, and universal, transcultural goods and rights that underpin the authority of the international human rights regime in theory and practice. It does so while recognizing the serious epistemological challenges to this universalist conception, chiefly: how a social construct can be both time-bound human creation and continue to be morally binding across space, time, and the accelerated change global citizens of all corners are experiencing, simultaneously yet in their own way.

A characteristics of Contemporary Occidental Cultural machinery is making Ethics a central point concerning to the several spheres of human activity, including the action of mass media, crossing public health problems and economic questions, and coming to political activity, new technologies development and ecology.

We think the present moment is a timely one for debating the relation between evidentiary protocols and academic disciplines. Since academic practices for constituting and deploying evidence tend to be discipline-specific, the much-discussed crisis of the disciplines in recent years has given rise to a series of controversies about the status of evidence in current modes of investigation and argument: deconstruction, gender studies, new historicism, cultural studies, new approaches to the history and philosophy of science, the critical legal studies movement, (...) and so on. Unfortunately, these controversies too often devolve into oversimplified debates about who has the evidence and who does not, who did their homework and who did not, or about the dangers of an ill-defined academic relativism. Attention needs to be better and otherwise directed: at the configuration of the fact-evidence distinction in different disciplines and historical moments, for example; or at the relative function of such notions as “self-evidence,” “experience,” “test,” “testimony,” and “textuality” in various academic discourses; or at the ways in which the invoked “rules of evidence” are themselves the products of historical developments, and themselves undergo redifferentiation and reformulation.

The manifest image is teeming with activity. Objects are booming and buzzing by, changing their locations and properties, vivid perceptions are replaced, and we seem to be inexorably slipping into the future. Time—or at least our experience in time— seems a very turbulent sort of thing. By contrast, time in the scientist image seems very still. The fundamental laws of physics don’t differentiate between past and future, nor do they pick out a present moment that flows. Except for a minus (...) sign in the relativistic metric, there are few differences between the temporal and spatial coordinates in natural science. We seem to have, to echo another debate, an “explanatory gap” between time as we find it in experience and as we find it in science. Reconciling these two images of the world is the principal goal of philosophy of time. (shrink)

This book approaches classic epistemological problems from a contextualist perspective. The author takes as his point of departure the fact that we are situated beings, more specifically that every single moment in our lives is already given within the framework of a specific context in the midst of which we understand ourselves and what surrounds us. In the process of his investigation, the author explores, in a fresh way, the works of key thinkers in epistemology. These include Bernard Bolzano, René (...) Descartes, Gottlob Frege, Edmund Husserl, Immanuel Kant and Ludwig Wittgenstein, but also contemporary authors such as Stewart Cohen, Keith DeRose, David Lewis, Duncan Pritchard, Ernest Sosa and Charles Travis. Some of the topics covered are attributions of knowledge, the correspondence theory of truth, objectivity and subjectivity, possible worlds, primary and secondary evidence, scepticism, transcendentalism and relativism. The book also introduces a new contextualist thought-experiment for dealing with moral questions. Contextualism has received a great deal of attention in contemporary epistemology. It has the potential to resolve a number of issues that traditional epistemological approaches cannot address. In particular, a contextualist view opens the way to an understanding of those cognitive processes that require situational information to be fully grasped. However, contextualism poses serious difficulties in regard to epistemic invariance. This book offers readers an innovative approach to some fundamental questions in this field. (shrink)

The special theory of relativity (STR) is widely supposed to be in tension with A-theories of time, those giving special significance to the present moment. A-theories are diverse in the features they regard as distinctive of the present, but all agree that there is an absolute fact of the matter about which events have the feature of presentness. Famously, the standard notion of simultaneity operationalised within the theory of relativity is not absolute. If A-theorists accept relativistic physics, they must (...) either refine their A-theory and sever joint presentness from simultaneity (‘conciliatory’ responses to the problem), or supplement standard relativity by adding further spacetime structure that grounds a relation of absolute simultaneity (‘supplementing’ responses). This chapter considers the prospects for such approaches, concluding that while there is no knock-down argument from relativity against the A-theory, attempts to marry the A-theory with STR are more trouble than they are worth.

Where the old objectivity question asked, Objectivity or relativism: which side are you on?, the new one refuses this choice, seeking instead to bypass widely recognized problems with the conceptual framework that restricts the choices to these two. It asks, How can the notion of objectivity be updated and made useful for contemporary knowledge-seeking projects? One response to this question is the strong objectivity program that draws on feminist standpoint epistemology to provide a kind of logic of discovery for maximizing (...) our ability to block might makes right in the sciences. It does so by delinking the neutrality ideal from standards for maximizing objectivity, since neutrality is now widely recognized as not only not necessary, not only not helpful, but, worst of all, an obstacle to maximizing objectivity when knowledge-distorting interests and values have constituted a research project. Strong objectivity provides a method for correcting this kind of situation. However, standpoint approaches have their own limitations which are quite different from the misreadings of them upon which most critics have tended to focus. Unfortunately, historically limited epistemologies and philosophies of science are all we get to choose from at this moment in history. (shrink)

In the "Republic," Plato has Socrates attack poetry’s use of mimēsis, often translated as ‘imitation’ or ‘representation.’ Various scholars (e.g. Blondell 2002; Frank 2018; Halliwell 2009; K. Morgan 2004) have noticed the tension between Socrates’ theory critical of mimēsis and Plato’s literary practice of speaking through various characters in his dialogues. However, none of these scholars have addressed that it is not only Plato the writer who uses mimēsis but also his own character, Socrates. At crucial moments in several (...) dialogues, Socrates takes on a role and speaks as someone else. I call these moments “Socratic mimēsis.” While previous commentators have noticed some of these moments, they have either overstated their rarity or they have not studied them collectively. My dissertation is the first in-depth investigation of this phenomenon in the dialogues. Socrates’ dramatic imitation of others is way of teaching in a voice separate from his own, and it is also a way for Plato to speak to, and to educate, different kinds of audiences. Although “Socratic mimēsis” occurs throughout the Platonic corpus, I focus on three passages from three different dialogues, which are paradigm instances: [1] in the "Crito" Socrates plays the part of ‘the Laws’ (50a-54c); [2] in the "Theaetetus" he acts the part of ‘Protagoras’ (166a-168c); and [3] in the "Menexenus" he recites a funeral speech learned from ‘Aspasia’ (236d-249c). Instead of one-sidedly reading the dialogues as either only literary works of art or as only a series of philosophical arguments, this study gleans philosophic insights from the literary and dramatic details of the dialogues. In chapter one I argue that in the "Crito" Socrates tries to convince Crito of a universal and absolute ethics based on never committing injustice, but Crito is not able to understand. In order to make Crito more just—but not yet at the level of Socratic ethics—Socrates creates ‘the Laws’ to persuade Crito to expand his personal notion of justice. Socrates instills a political obedience in place of Crito’s existing lawlessness as a second-best recourse. Plato expects the astute listener or reader to see the contrast between Socrates’ earlier ethical principles, said in his own voice, with what he says in the voice of ‘the Laws.’ In chapter two I argue that in the part of the "Theaetetus" where Socrates defends Protagoras (often called ‘the Defense’), Socrates, by imitating ‘Protagoras,’ is actually criticizing Protagorean relativism. The Protagorean theory cannot account for mimēsis and Socrates’ mimetic act performatively contradicts the identity of appearance and reality, which the theory presupposes. Finally, in chapter three I argue that in the Menexenus the funeral oration that Socrates recounts for Menexenus that he heard from ‘Aspasia’ is actually a disguised criticism of political rhetoric and of Athenian imperialism. Although the speech is never interrogated within the dialogue, Plato provokes the listener or reader outside the dialogue to question its message and to see how it conflicts with many of Socrates’ positions in other dialogues. Beyond reconsidering the long-standing and persistent view that Plato was against poetry and mimetic performance, I re-examine the role that performance and role-playing can have in philosophy and pedagogy more generally. Actors, by taking on other personas, and audience members, in observing actors and their actions, are both involved in acts of imagination that can expand their horizon of thinking and feeling.

Focusing solely on the near-death cognizance of the dying, rather than the material perspective of the living, reveals a new understanding of death. Its significance to psychology, philosophy, and religion is huge for what emerges is a long overlooked phenomenon: a nonsupernatural, relativistic, and timelessly eternal consciousness, which can be a natural afterlife. Ironically, the validity of the theory of a natural eternal consciousness (NEC) assumes the loss of all materially based consciousness with death—more specifically, the permanent loss of (...) time perception. The theory claims, and the article deduces from empirical knowledge, that by imperceptibly entering the timelessness before death, one’s last conscious moment, whatever the type, becomes by default—psychologically, from one’s perspective—a forever present moment. To help explain and validate the theory, the article presents thought experiments and a formal model of all of life’s moments and all transitions between periods of time perception and those of timelessness. An open-minded reading should reveal that the NEC does not threaten faith in a god or a heaven. (shrink)

This is a discussion of how we can understand the world-view given to us by the Everett interpretation of quantum mechanics, and in particular the role played by the concept of 'world'. The view presented is that we are entitled to use 'many-worlds' terminology even if the theory does not specify the worlds in the formalism; this is defended by means of an extensive analogy with the concept of an 'instant' or moment of time in relativity, with the lack of (...) a preferred foliation of spacetime being compared with the lack of a preferred basis in quantum theory. Implications for identity of worlds over time, and for relativistic quantum mechanics, are discussed. (shrink)

Recent years have seen a continual rise of interest in the empirical study of questions traditionally located in moral philosophy, i.e., studies in Experimental Ethics. In this chapter we briefly outline the recent history of this field. To do so we have to cross disciplinary borders to quite some extent. Tracing the beginnings of Experimental Ethics back to early works in moral psychology, we delineate a sequence of theories which eventually flow into current Experimental Ethics. We then briefly review four (...) topics which are intensively investigated in Experimental Ethics at the moment: moral relativism, individual and cross-cultural differences in moral judgment, and interactions of moral evaluation with other philosophical concepts. We conclude with a short historically informed comment on the demarcation problem of Experimental Ethics. (shrink)

Dans les tentatives pour donner à la philosophie un fondement nouveau, le concept d’essence constitue le point central de la discussion, La phénoménologie de Husserl aussi bien que Feidétique de Scheler et de ses successeurs avait pour but de fonder, grâce à la doctrine de l’essence, une connaissance absolument certaine des vérités intemporelles. Cette prétention montre que la doctrine moderne de l’essence est la dernière étape de la pensée bourgeoise dont l’origine est la philosophie de Descartes. L’article se propose d’interpréter (...) les différentes conceptions de l’essence en tant que moments de l’évolution historique de cette pensée bourgeoise. La bourgeoisie dans sa période ascendante exigeait des vérités essentielles qu’elles fussent capables de se justifier devant la raison critique autonome de l’individu : au contraire la philosophie moderne fait de l’essence l’objet d’une intuition que la raison doit accepter telle quelle. Les tendances rationnelles de la doctrine de l’essence sont refoulées : la raison devient réceptrice, hétéronome. Cette démission de la raison critique reflète l’adaptation de la philosophie à l’idéologie antirationaliste des systèmes nouveaux d’autorité : dans la dernière phase de l’évolution, la doctrine de l’essence devient mythologie politique. Le positivisme représente l’opposition non dialectique à cette doctrine de l’essence : il veut entièrement chasser de la science le concept d’essence, mais du même coup il tombe dans le défaut de rabaisser tous les faits sur le même plan, sans établir entre eux de différences. Dans l’idée d’essence opposée au phénomène sont contenus des éléments positifs, critique de la réalité « mauvaise », processus de réalisation des possibilités aflxthentiques de l’homme et des choses. Ces éléments positifs, la doctrine dialectique de l’essence les conserve. — La deuxième partie du travail cherche à montrer la formation du concept d’essence dans la philosophie dialectique qui, grâce à ce concept, surmonte le relativisme sans retomber dans la métaphysique dogmatique. L’opposition de l’essence et du phénomène est conçue ici comme une relation historique, et dans la constitution de celle-ci les intérêts sociaux de la théorie pénètrent à titre d’élément constitutif. La praxis historique à laquelle la théorie est liée et qui doit supprimer (aufheben) l’opposition, rend les intérêts particuliers vraiment généraux et fonde un type nouveau de vérité universelle. Le concept d'essence qui est au centre de la doctrine dialectique et qui détermine tous les autres concepts est le concept de l’homme. Le souci d’atteindre l’homme véritable remplace le souci de connaissance absolument certaine qui caractérise la philosophie idéaliste. De même que les formes phénoménales de l’henime et des choses ont leur origine dans la structure sociale présente, ainsi cette structure dessine à l’avance l’image de l’essence et des possibilités humaines que l’homme doit comprendre comme des tâches historiques, dont la voie de réalisation est marquée par la réalité elle-même.During the last decades the concept of essence has been widely discussed in the various attempts to seek a new foundation for philosophy. Both the phenomenology of E. Husserl and the theory of essence of M. Scheler and his followers were devoted to discovering through their theories of reality the unconditioned and exact knowledge of eternal verities. This attempt characterizes modern theory of reality as the last stage of bourgeois thought which began with Descartes. — The article endeavors to interpret the various conceptions of essence as specific stages of the historical development of that thought. With the rise of modern society the demand was made that the essential verities justify themselves before the critical and autonomous reason of the individual, whereas contemporary theory regards them as objects of an intuition and believes that reason has to accept them in the way in which they manifest themselves. The critical and rational tendencies in the theory of reality are abandoned, reason becomes receptive and heteronomous. This abdication of autonomous critical reason mirrors the adjustment of philosophy to the anti-rational ideology of the new form of authoritarian state. In the last phase of development the theory of reality turns out to be political mythology. — Positivism represents the undialectical opposition to this theory of reality. It wishes to remove completely the concept of essence from science, but thereby arrives only at an indifferent levelling of all facts. The idea of reality as opposed to appearance contains the positive elements of a critique of reality and of the process of realization of the essential potentialities of man and things. They are preserved in the dialectical conception of reality. — The second part of the essay attempts to point out the function of the concept of reality in dialectical philosophy, with the help of which it overcomes relativism. The opposition between appearance and reality is here conceived as a historical relationship, in the determination of which enter as integral elements the social interests of the theory. In the course of the historical trend, with which the theory is bound up and which is supposed to abolish the opposition between appearance and reality, the particular interests become truly general, and a new kind of universally valid truth arises. Reality which stands at the center of the dialectical theory and determines all other concepts, refers primarily to the essence of man. Concern about concrete man is taking the place of concern about the unconditioned exact truth of idealist philosophy. In the same way as man’s (and thing’s) forms of appearance is grounded in the present social structure, likewise the idea of his essence and the process of its realization arise out of this structure, and its realization must be conceived as a historical task.

I examine the issue of persistence over time in thecontext of the special theory of relativity (SR). Thefour-dimensional ontology of perduring objects isclearly favored by SR. But it is a different questionif and to what extent this ontology is required, andthe rival endurantist ontology ruled out, by thistheory. In addressing this question, I take theessential idea of endurantism, that objects are whollypresent at single moments of time, and argue that itcommits one to unacceptable conclusions regardingcoexistence, in the context of (...) SR. I then propose anddiscuss a plausible account of coexistence forperduring objects, which is free of these defects. This leaves the endurantist room for some maneuvers. I consider them and show that they do not really helpthe endurantist out. She can accommodate the notionof coexistence in the relativistic framework only atthe cost of renouncing central endurantist intuitions. (shrink)

Special relativity has been understood by many as vindicating a tenseless conception of time, denying the existence of tensed facts and a fortiori objective temporal passage. The reason for this is straightforward: both passage and the obtaining of tensed facts require a universal knife-edge present moment—yet this structure is not easily reconcilable with the relativity of simultaneity. The above being said, the prospects for tense and passage are sometimes claimed to be improved on moving to cosmological solutions of general relativity. (...) In this paper, we evaluate in detail these arguments, finding that there remain several open questions to be addressed if the introduction of tensed facts into the relativistic context is to be compelling. Moreover, we argue that, even setting aside these issues, objective tense stands and falls in relativity for exactly the same reasons that it does in classical philosophical discussions on the matter.

There are two main theories about the persistence of objects through time: endurantism and perdurantism. Endurantists hold that objects are three-dimensional, have only spatial parts, and wholly exist at each moment of their existence. Perdurantists hold that objects are four-dimensional, have temporal parts, and only partly exist at each moment of their existence. In this paper we argue that endurantism is poorly suited to describe the persistence of objects in a world governed by Special Relativity, and can accommodate a (...) class='Hi'>relativistic world only at a high price, one that we argue is not worth paying. Perdurantism, on the other hand, fits beautifully with our current scientific understanding of the world. Furthermore, we make this argument from implications of the Lorentz transformations, without appeals to geometrical interpretations, dimensional analogies, or auxillary premises like temporal eternalism.

A physical and mathematical framework for the analysis of probabilities in quantum theory is proposed and developed. One purpose is to surmount the problem, crucial to any reconciliation between quantum theory and space-time physics, of requiring instantaneous “wave-packet collapse” across the entire universe. The physical starting point is the idea of an observer as an entity, localized in space-time, for whom any physical system can be described at any moment, by a set of (not necessarily pure) quantum states compatible with (...) his observations of the system at that moment. The mathematical starting point is the theory of local algebras from axiomatic relativistic quantum field theory. A function defining thea priori probability of mistaking one local state for another is analysed. This function is shown to possess a broad range of appropriate properties and to be uniquely defined by a selection of them. Through a general model for observations, it is argued that the probabilities defined here are as compatible with experiment as the probabilities of conventional interpretations of quantum mechanics but are more likely to be compatible, not only with modern developments in mathematical physics, but also with a complete and consistent theory of measurement.

This article exploits the “binary license” offered by the title of the symposium in which it appears (“Comparative Relativism”) as a kind of promise of connection. The author suggests, however tentatively, that in the challenge of heterogeneity, fractality, perspective/-alism, and multiplicities lies the power of the forking pathway: the moment a relation is created through divergence. If we are invited—in the same breath—to consider forms of comparison and forms of relativism (dropping difference and similarity), we are also offered two paths, (...) one based on a world of singularities and multiplicities, and the other on a world of not-quite repetitions. The article asks if the binary is not essential to the epistemic work that Western (Euro-American) scholars might want to do, since we forever reinvent the divide between the modern and the post-/pre-modern. Strathern assumes the anthropologist's license to talk about concepts through persons, and begins by asking how Papua New Guineans who come together in a city compare themselves, and in contrast to ethnic comparisons elsewhere (e.g., contra Sarah Green's Balkan interactions). In talking about persons through concepts, it is worth asking what is entailed in relativizing one scholar's work through that of another. The author says that her “hunch” is that in both cases the analyst might wish to have the liberty of discerning—in the same breath—the multiplicities of what John Law and Annemarie Mol call perspectivalism (their very general alternative to comparison) and Eduardo Viveiros de Castro's radically divergent perspectivism (a self-contained, recursive and above all socially specific relativism).
