Consequentialists typically think that the moral quality of one's conduct depends on the difference one makes. But consequentialists may also think that even if one is not making a difference, the moral quality of one's conduct can still be affected by whether one is participating in an endeavour that does make a difference. Derek Parfit discusses this issue – the moral significance of what I call ‘participation’ – in the chapter of Reasons and Persons that he devotes to what he (...) calls ‘moral mathematics’. In my paper, I expose an inconsistency in Parfit's discussion of moral mathematics by showing how it gives conflicting answers to the question of whether participation matters. I conclude by showing how an appreciation of Parfit's error sheds some light on consequentialist thought generally, and on the debate between act- and rule-consequentialists specifically. (shrink)

The meaning of Lorentz contraction in special relativity and its connection with Bell’s spaceships parable is discussed. The motion of Bell’s spaceships is then compared with the accelerated motion of a rigid body. We have tried to write this in a simple form that could be used to correct students’ misconceptions due to conflicting earlier treatments.

In this paper I will present conceptions of state reduction and particle and/or system localization which render these subjects fully compatible with the general requirements of a relativistic, i.e. Lorentz invariant, quantum theory. The approach consists of a systematic generalization of the concepts of initial data assignment at definite times, initiation and completion of measurements at definite times, and dynamical evolution as time dependence, to the concepts of initial data assignment on arbitrary space-like hyperplanes, initiation and completion of measurements (...) on arbitrary space-like hyperplanes, and dynamical evolution as space-like hyperplane dependence, respectively. I also briefly discuss the superluminal propagation which emerges from the localization study and the manner in which causal anomalies are nevertheless avoided. (shrink)

Well-Being and Death addresses philosophical questions about death and the good life: what makes a life go well? Is death bad for the one who dies? How is this possible if we go out of existence when we die? Is it worse to die as an infant or as a young adult? Is it bad for animals and fetuses to die? Can the dead be harmed? Is there any way to make death less bad for us? Ben Bradley defends the (...) following views: pleasure, rather than achievement or the satisfaction of desire, is what makes life go well; death is generally bad for its victim, in virtue of depriving the victim of more of a good life; death is bad for its victim at times after death, in particular at all those times at which the victim would have been living well; death is worse the earlier it occurs, and hence it is worse to die as an infant than as an adult; death is usually bad for animals and fetuses, in just the same way it is bad for adult humans; things that happen after someone has died cannot harm that person; the only sensible way to make death less bad is to live so long that no more good life is possible.

Inertial frames and Lorentz transformations have a preferred status in the special theory of relativity (STR). Lorentz transformations, in turn, embody Einstein's convention that the velocity of light is isotropic, a convention that is necessary for the establishment of a standard signal synchrony. If the preferred status of Lorentz transformations in STR is not due to some particular bias introduced by a convention on signal synchronism, but to the fact that the Lorentz transformation group is the (...) symmetry group of the theory, then the signal synchronism is not a matter of convention but rather a matter of fact. In order to explore the conventionalist thesis, that within the frame of STR isotropy in the velocity of light and, hence, signal synchronism is a matter of convention, we need a generalized Lorentz transformation group that does not embody Einstein's isotropy convention, and upon which STR can be based. We present here a new approach to the resulting search for a generalized STR, which is well suited for establishing some well-known results of Winnie as well as some new results. (shrink)

The purpose of this paper is to show that the Lorentz contraction of a rod is possible only if the rod’s world path is a real four-dimensional object. This result demonstrates that special relativity does require reality at the microscopic level to be a four-dimensional world represented by Minkowski spacetime.

In support of their contention that it is the absence of a subsisting medium that imbues the speed of light with fundamentality, Bryan Cheng and James Read discuss certain “fishbowl universes” in which physical influences evolve, not at the speed of light, but that of sound. The Lorentz transformation simulated in these sonic universes, which the authors cite from the literature of analogue gravity, is not that of Einstein, for whom an aether was “superfluous”, but that of the earlier (...) relativity of Lorentz and Poincaré, which did suppose such a medium. The authors’ intention is not to argue analogically, but simply to contrast the situation of light with that of sound. However, I argue that these universes are too successful as analogues to support the authors’ case. By reducing Lorentzian relativity to its bare essentials, they provide a compelling demonstration of the viability and explanatory strengths of the earlier theory. They show how a thoroughly wave-theoretic treatment of the elementary particles would explain why all aspects of matter transform in like manner, thereby avoiding a difficulty that was a significant reason for the demise of Lorentzian relativity after 1905. Importantly, these sonic universes suggest a unifying explanation, not only of the Lorentz transformation and de Broglie wave, but of the principle of relativity, which was merely postulated, rather than explained, by Einstein in 1905.

Relative distance and velocity magnitudes between two arbitrarily moving particles are independent of an observer's reference frame, and may be used to construct theoretically a clock whose rate is Lorentz-invariant. This result is in accord with the principle of relativity, using the interaction interpretation: Relativistic changes arise in association with momentum-energy transfer, rather than in consequence of velocity-induced changes in measuring clocks and rods.

I address a number of questions concerning the interpretation of local time and the corresponding states theorem (CST) of the Versuch, questions which have been addressed either incompletely or inadequately in the secondary literature. In particular: (1) What is the relation between local time and the behavior of moving clocks? (2) What is the relation between the primed field variables and the electric and magnetic fields in a moving system? (3) What is the relation of the CST to the principle (...) of relativity and requirements of covariance? (4) Does the introduction of local time and the primed field variables constitute a hypothesis, i.e., an addition to or a modification of the basic theory? (shrink)

We consider a representation of the state reduction which depends neither on its reality nor on the details of when and how it emerges. Then by means of the representation we find necessary conditions, even if not the sufficient ones, for a decomposition of the state vector space to be a solution to the basis problem. The conditions are that the decomposition should be Lorentz invariant and orthogonal and that the associated projections should be continuous. They are shown to (...) be able to determine a decomposition in each of a few examples considered if the other circumstances are taken into account together. (shrink)

The Lorentz transformation of space and time between two reference frames is one of the pillars of the special relativity theory. As a result of the Lorentz transformation, space and time are only relative and are entangled, while the Minkowski metric is Lorentz invariant. For this reason, the Lorentz transformation is one of the major obstructions in the development of physical theories with quantized space and time. Here is described the Lorentz transformation of a physical (...) system with a discrete dynamical time and a continuous space that fulfills Lorentz invariance while approximating the Lorentz transformation at the time continuous limit and the Galilei transformation at the classical limit. Furthermore, the discreteness of time is not mixed with the continuous nature of space, making time distinct from space. (shrink)

This essay highlights Ben-Ami Scharfstein’s major philosophical projects: first, philosophizing that includes nonwestern philosophies, especially Chinese and Indian, and that creates a dialogue between philosophers and philosophical traditions without prioritizing any of them, and without taking western philosophy as the point of departure. Second, a similar, inclusive move in the field of art, art without borders if you wish. Here the inclusivity applies not just to east and west, north and south, but even to animal-made art. Just as he wrote (...) about philosophy in China and India, attempting to say something broader about humanity and humanism, so too does Scharfstein’s argument about animals and art have far-reaching implications, above and beyond the question of the demarcation of art. He aims to tell us something about the human-animal relationship, about lack of solidarity between fellow inhabitants of planet earth, not just humans, and about cruelty and exploitation and blindness to the other, whichever other. And finally, I touch on Scharfstein’s work The Philosophers, beautifully translated into Hebrew as Philosophers as Human Beings, where “he dares to imply that philosophizing is in fact a sublimated expression of the unconscious,” as Yoav Ariel—sinologist and much more—puts it. Such a move, Ariel continues to argue, “dethrones philosophy of its unique position of honor and supremacy, and disperses the atmosphere of conceptual terror that philosophy created generation after generation.”.

Aaron Ben-Ze'ev carries out what he calls "a careful search for general patterns in the primeval jungle of emotions.".

The Lorentz-formulae are deduced from three factual statements the physical meaning of which is explained in terms of operations with clocks, light-signals and measuring rods. These statements are: (1) The time-length of a process is invariant. (2) The velocity of light is the same in all inertial systems. (3) The velocity of light is independent of the source. It is also shown that these statements can be deduced from the Lorentz-formulae. They are the physical content of the latter. (...) The principle of relativity and the light-principle together, however, contain more physical meaning than the Lorentz-formulae. Operational definitions are given for all relevant concepts. (shrink)

Ben Fine traces the origins of social capital through the work of Becker, Bourdieu and Coleman and comprehensively reviews the literature across the social sciences. The text is uniquely critical of social capital, explaining how it avoids a proper confrontation with political economy and has become chaotic. This highly topical text addresses some major themes, including the shifting relationship between economics and other social sciences, the 'publish or perish' concept currently burdening scholarly integrity, and how a social science interdisciplinarity requires (...) a place for political economy together with cultural and social theory.

I argue that extant accounts of harm all fail to account for important desiderata, and that we should therefore jettison the concept when doing moral philosophy.

In a recent paper in this journal which was part of a panel discussion of Grünbaum's philosophy of science, M. G. Evans discusses the Lorentz-Fitzgerald contraction hypothesis and related matters [2]. The purpose of this note is to clarify and correct some of the points in Evans' paper.

This paper defends the view, put roughly, that to think that p is to guess that p is the answer to the question at hand, and that to think that p rationally is for one’s guess to that question to be in a certain sense non-arbitrary. Some theses that will be argued for along the way include: that thinking is question-sensitive and, correspondingly, that ‘thinks’ is context-sensitive; that it can be rational to think that p while having arbitrarily low credence (...) that p; that, nonetheless, rational thinking is closed under entailment; that thinking does not supervene on credence; and that in many cases what one thinks on certain matters is, in a very literal sense, a choice. Finally, since there are strong reasons to believe that thinking just is believing, there are strong reasons to think that all this goes for belief as well. (shrink)

We review several no-go theorems attributed to Gisin and Hardy, Conway and Kochen purporting the impossibility of Lorentz-invariant deterministic hidden-variable model for explaining quantum nonlocality. Those theorems claim that the only known solution to escape the conclusions is either to accept a preferred reference frame or to abandon the hidden-variable program altogether. Here we present a different alternative based on a foliation dependent framework adapted to deterministic hidden variables. We analyse the impact of such an approach on Bohmian mechanics (...) and show that retrocausation necessarily comes out without time-loop paradox. (shrink)

We show how a recently introduced retarded version of the Bohm Model evades the Hardy proof that hidden-variable models must violate Lorentz Invariance. We also discuss a possible test of such models.

Uma interpretação corrente do fenômeno social ensina que todos os bens coletivos são bens convergentes. As concepções bem-estarista e utilitarista na economia e na filosofia, respectivamente, são os seus principais expoentes. A tese consiste em aceitar que “totalidades sociais” são inexoravelmente compostas de “partes” e que, por isso, na base de cada bem público ou social se encontrariam sempre os indivíduos, os quais seriam, em última análise, responsáveis pela sua existência. Assim, os bens públicos seriam bens para os quais convergem (...) interesses e escolhas dos agentes sociais. O presente estudo mostra, em primeiro lugar, segundo a compreensão de Taylor, que nem todos os bens coletivos são bens convergentes. Alguns bens sociais podem ser considerados bens irredutivelmente sociais, cuja justificativa se encontra na reflexão sobre o significado. Em segundo lugar, aborda a contribuição que a noção hegeliana de eticidade teve sobre a formulação desse argumento. (shrink)

It is shown that the jet mechanism derivable from the Lorentz deformation picture leads to a nearly constant average jet transverse momentum. It is pointed out that this is consistent with the high-energy experimental data. It is pointed out further that this result strengthens the physical basis for the minimal time-energy uncertainty combined covariantly with Heisenberg's space-momentum uncertainty relation.

One prominent argument in international law and religious thought for abolishing capital punishment is that it violates individuals’ right to life. Notably, this _right-to-life argument_ emerged from normative and legal frameworks that recognize deadly force against aggressors as justified when necessary to stop their unjust threat of grave harm. Can capital punishment be necessary in this sense—and thus justified defensive killing? If so, the right-to-life argument would have to admit certain exceptions where executions are justified. Drawing on work by Hugo (...) Bedau, I identify a thought experiment where executions are justified defensive killing but explain why they cannot be in our world. A state’s obligations to its prisoners include the _obligation to use nonlethal incapacitation_ (ONI), which applies as long as prisoners pose no imminent threat. ONI precludes executions for reasons of future dangerousness. By subjecting the right-to-life argument to closer scrutiny, this article ultimately places it on firmer ground. (shrink)
