After discussing in the first five sections the meaning and the difficulties of the principle of relativity we present a new sel of spacetime transformations between inertial systems (“inertial” transformations), based on three assumptions: (1) The two-way velocity of light is c in all inertial systems and in all directions; (2) Time dilation effects take place with the usual relativistic factor; (3) Clocks are synchronized in the way chosen by nature itself, e.g., in the Sagnac effect. We show that our (...) new transformation laws can explain the available experimental evidence in spite of the implied noninvariance of the one-way velocity of light. (shrink)

Fundamental experiments on the dual nature of atomic entities (photons, electrons, neutrons, etc.) can be interpreted in terms of “empty” waves not carrying energy and momentum. Similar points of view were advanced in famous papers by Einstein, de Broglie, Bohr, and Born. Recent proposals could lead to experimental tests of this idea, using low intensity photon beams, thanks to modern experimental apparatuses.

After some considerations about the equivalence of the objective local theories to the deterministic theories of Bell's type, a simple and systematic way to deduce inequalities from Einstein locality is introduced: All the inequalities deduced by Bell and by other authors, as well as several new ones, are so obtained. Some theorems are proven which show how striking the difference is at small angles between a correlation function satisfying Einstein locality and the quantum mechanical one. Experiments at small angles involve (...) weaker additional assumptions than those used up to now in experimental research on Bell's inequality. (shrink)

The experimental evidence for electromagnetic signals propagating with superluminal group velocity is recalled. Transformations of space and time depending on a synchronization parameter, e1, indicate the existence of a privileged inertial system. The Lorentz transformations are obtained for a particular e1≠0. No standard experiment on relativity depends on e1, but if accelerations are considered only e1=0 remains possible. The causal paradox generated by superluminal signals (SLS) in the theory of relativity does not exist in the theory with e1=0. The irrelevance (...) of SLS for the Einstein, Podolsky and Rosen paradox is pointed out. (shrink)

A generalized reality criterion which attributes physical properties to statistical ensembles is used in order to deduce an inequality which is violated by quantum mechanics in realistic conditions. This new form of the Einstein-Podolsky-Rosen paradox is developed exclusively from the reality criterion and from separability without any use of the previously introduced restrictive assumptions about the probabilistic scheme.

We formulate a model of EPR experiments by including variables determining whether a photon will be detected or not. The resulting deterministic model satisfies Bell's original inequality even though it can agree exactly with the quantum mechanical predictions for the performed experiments. It violates variations of the inequality used in the interpretation of the experiments and deduced with the help of additional assumptions.

The traditional approach to light amplification is shown to be based on the idea that photons of the incoming beam act as independent particles. If atomic stimulation is instead attributed to the action of the wave, a different photon distribution is obtained in the final state. The new distribution turns out to be Poissonian, in agreement with some experimental evidence. The expected rate of coincidences for an empty-wave amplification experiment is calculated, and found up to 30% higher than obtained from (...) the traditional approach. (shrink)

Old and recent ideas concerning the nature of time are reviewed, starting from Mach's refusal of Newton's absolute time. Many experiments show that the slowing down of moving clocks is a real phenomenon. Such must then also be the so-called “twin paradox,” which owes its name to its evident incompatibility with the philosophy of relativism (not to be confused with the theory of relativity). The Lorentz reformulation of special relativity started by postulating physical effects of the ether, but accepted Einstein's (...) clock synchronization. Only because of this Lorentz could not understand the advantages of an easily deducible different theory. As stressed by Popper, one of the main problems of the usual approach is the introduction of a superdeterministic universe. Recent results obtained by the author show that a theory is possible, based on relative time but on absolute simultaneity, in which the conceptual difficulties of relativity are avoided. (shrink)

Popper's idea of propensities constituting the physical background of predictable probabilities is reviewed and developed by introducing a suitable formalism compatible with standard probability calculus and with its frequency interpretation. Quantum statistical ensembles described as pure cases (“eigenstates”) are shown to be necessarily not homogeneous if propensities are actually at work in nature. An extension of the theory to EPR experiments with local propensities leads to a new and more general proof of Bell's theorem. No joint probabilities for incompatible observables (...) need to be introduced. (shrink)

The results of a previous paper for the properties of the correlation functionP(θ) at small angles following from Einstein locality are extended to the general case whereP(0)≠−1. Experimental investigations are suggested to check the validity of some theorems on the behavior of the correlation functionP(θ) which are deduced directly from Einstein locality.

First it is proved that, in a deterministic theory, Malus' law requires that, if a photon is successively transmitted by two polarizers with appropriately chosen settings, the first transmission influences a hidden variable (co-) determining the second one. We derive from this that in an ideal EPR experiment (giving the result predicted by quantum mechanics for two correlated photons transmitted by two polarizers with suitably chosen settings) there has to be a nonlocal influence from the “first” transmission interaction to the (...) second. Subsequently we argue that we can abandon determinism as an assumption so that the locality hypothesis is in any case untenable if the predictions of quantum mechanics are all correct. (shrink)

We show that a method exists for deducing from Einstein locality all the possible inequalities for linear combinations of correlation functions. This allows us to show also that there is a complete observational equivalence of deterministic local theories and probabilistic local theories.

Probabilistic local realism for two correlated systems as formulated by Clauser and Horne in 1974 is shown to be necessarily based on a perfect specification of the state and on an individual definition of probability. All known realistic formulations of probability calculus are instead defined in terms of relative frequencies, and perfect specifications of states are impossible. We reformulate probabilistic local realism by using the relative frequency definition only and show that the Einstein, Podolsky, and Rosen paradox still obtains.

In this paper I want to do the following things. First I want to show that in the part of the Theaetetus where the relationship between knowledge and perception is examined, the concept of knowledge that is in question is very clearly characterized. We are left in no doubt as to what is to count as knowing. Secondly I want to unravel in some detail the case that Socrates puts on Protagoras’ behalf where he draws on what Protagoras actually wrote (...) (151 E-152C); as opposed to what he may have taught secretly to his pupils (152C-160D). Thirdly I wish to argue that if we let the dialogue speak for itself, it is manifest that this case put up on Protagoras’ behalf at 151 E-152C is not overthrown; it is not even shaken. (shrink)

That is, he restricts the use of the word by setting down what he will consider to be the essential characteristics of knowledge, the sufficient and necessary conditions of its being instantiated. An excellent piece of philosophical procedure. (shrink)

It is not quite as easy to see that there is in fact no formula of this modal language having the same truth conditions (in terms of S5 Kripke semantics) as (1). This was rst conjectured by Allen Hazen2 and later proved by Harold Hodes3. We present a simple direct proof of this result and discuss some consequences for the logical analysis of ordinary modal discourse.

Because anticipated and retrospective regret play important roles in practical deliberation and motivation, better understanding them can illuminate the contours of human agency. However, the possibility of self-ignorance and the fact that we change over time can make regret—especially anticipatory regret—not only a poor predictor of where the agent will be in the future but also an unreliable indicator of where the agent stands. Granting these, this paper examines the way in which prospective and, particularly, retrospective regret can nevertheless yield (...) important insight into the sorts of creatures we are, both generally and individually. The experience of retrospective regret can show a person she values something in a way she did not know or that she is (or was) a different person than she had thought, insights which can factor into forward-looking, or prospective, deliberation. Such instances of revelatory regret reveal something to the agent about herself as agent. I examine two cases of agential self-ignorance. In the first, the experience of regret reveals what the agent values, not only to others but even to the agent himself. In the second, the agent anticipates experiencing regret for an action but does not experience the regret, suggesting that the agent did not value the rejected alternative in the way she thought. Anticipatory regret is forward-looking and can play an important role in practical deliberation. But insofar as anticipatory regret flows from one’s imperfect judgment and prospection about oneself, retrospective regret can be an important corrective in helping the agent understand her own standpoint.

The present book is intended to help students overcome difficulties by presenting Jaspers' thoughts in comparatively clear and straightforward fashion. While it denies that philosophy is "practical" in any cheap and obvious sense, it follows Jaspers in attempting to avoid the otiose and emphasize the relevance of philosophy to matters of ultimate concern. Those who wish a more theoretical and systematic presentation may well call to mind that, as Heidegger's followers express it, Jaspers, like Kierkegaard- and to some extent Sartre- (...) quite deliberately spurned the "ontological" in favor of the "ontic.".

This book is about the interaction between literary studies and the philosophy of literature. It features essays from internationally renowned and emerging philosophers and literary scholars, challenging readers to join them in taking seriously the notion of interdisciplinary study and forging forward in new and exciting directions of thought. It identifies that literary studies and the philosophy of literature address similar issues: What is literature? What is its value? Why do I care about characters? What is the role of the (...) author in understanding a literary work? What is fiction as opposed to non-fiction? Yet, genuine, interdisciplinary interaction remains scarce. This collection seeks to overcome current obstacles and seek out new paths for exploration. (shrink)

That Oscar Wilde was a central figure for aestheticism needs no arguing; that he should be taken seriously as an aesthetician is perhaps a less obvious matter. While much of his work concerns itself with the traditional purview of aesthetics as a philosophical discipline, commentators have rarely granted his writings that attention to ideas qua ideas that marks off a philosophical interest in a writer's oeuvre from other types of analysis. A number of attempts to tackle Wilde's pronouncements in a (...) broadly philosophical fashion have been made through the decades.1 Most recent scholarship, however, has regarded Wilde... (shrink)

Con E = m c2 la teoria della relatività ha generato una conquista conoscitiva di enorme importanza. Tuttavia la stessa teoria ha svuotato di significato oggettivo questa scoperta affermando che i punti di vista divergenti dei diversi osservatori inerziali sul valore numerico di Esono equivalenti. Una recente critica della nozione relativistica del tempo ha spostato il baricentro concettuale della fisica dello spazio e del tempo verso l'esistenza di un sistema privilegiato, restituendo alla formula di Einstein tutta la sua importanza.

In his newly updated version of The Anatomy of a Constitutional Law Case, Alan F. Westin provides a documentary portrait of historically important constitutional law case, 'Youngstown Sheet & Tube Co. v. Sawyer, ' from its rise in a bargaining dispute in the steel industry during 1952 to the aftermath of its decision by the United States Supreme Court. Westin has added to his classic book additional materials and personal commentaries collected since the work was first published. The new information (...) covers what went on within the Truman administration, what went on within the Supreme Court when analyzing and resolving issues that come before it. Westin includes selections from transcripts, briefs and other official proceedings, adds notes describing each phase of the constitutional process, and a section of commentary and questions relating this case to others.

What does social justice require in contemporary societies? What are the requirements of social democracy? Who and where are the individuals and groups that can carry forward agendas for progressive social transformation? What are we to make of the so-called new social movements of the last thirty years? Is identity politics compatible with egalitarianism? Can cultural misrecognition and economic maldistribution be fought simultaneously? What of the heritage of Western Marxism is alive and dead? And how is current critical social theory (...) to approach these and other questions? Much of the most productive work done in recent social theory has revolved around such issues, in particular, around those concerning the relationship between the politics of recognition and the politics of distribution. After the intense theoretical focus over the last fifteen years or so on the issues of recognition politics—multiculturalism, multi-nationalism, identity politics, group-differentiated rights, the accommodation of difference, and so on—some social theorists have worried that attention has been diverted from important issues of distributive equality—systematic impoverishment, increasing material inequality, ‘structural’ unemployment, the growth of oligarchic power, global economic segmentation, and so on. While some critics seem to have adopted a blunt ‘it’s the economy, stupid’ line of criticism,1 others have attempted to develop an overarching, integrative theoretical framework adequate to the diverse issues concerning both economic and cultural justice. For example, Axel Honneth proposes that a suitably developed and normatively robust theory of intersubjective recognition can adequately integrate an analysis of apparently diverse contemporary struggles: those for a just division of labor and hence, a fair distribution of resources and opportunities, as well as those for a culture free of identity-deforming disrespect and denigration.

Since Mueller’s 1958 article calling Hegelian dialectics a “legend,” it has been fashionable to deny that Hegel used thesis-antithesis-synthesis dialectics. But in truth, Hegel’s Phenomenology of Spirit has 28 dialectics hidden on four outline levels, and The Philosophy of History has 10 more on three outline levels. In Phenomenology’s macrodialectic, Hegel’s nonsupernatural Spirit–all reality, everything in the universe, including man and artificial objects–advances from unconscious + union (thesis) to conscious + separation (antithesis) to a synthesis of conscious (from the antithesis) (...) + union (from the thesis). Previous interpretations of Phenomenology have missed this dialectic: they have assumed that Spirit’s journey begins with consciousness, whereas the journey actually begins in the primordial state of nature, before man arrives and provides Spirit with its Mind (the collective mind of man). Mind then misperceives itself as a multitude of separate alien “objects”–things other than itself. The macrodialectic and all other dialectics are based on Christianity’s Johannine separation-and-return mythology; all Hegelian dialectics separate from a concept in the thesis, going to that something’s opposite (antithesis), and then return to the thesis concept. Thus, in Hegel’s master-and-slave dialectic (God = master, man = slave), man advances from potential + freedom to actual + bondage (religiosity) to actual + freedom (atheism). Only Marx and Tillich understood Hegelian dialectics. Marx’s basic dialectic (one of four) saw history separating from and returning to Communism, going from communal ownership + poverty (primitive communism, or gens) to private ownership + wealth (slavery, feudalism, capitalism) to communal ownership + wealth (final communism). Tillich’s basic dialectic (one of many) separates from and returns to God, advancing from Yes to God + Yes to supernaturalism (theism) to No to God + No to supernaturalism (atheism) to Yes to God + No to supernaturalism (humanism: humanity is the nonsupernatural “God above the God of theism”).

A key philosophical feature of Peter Jackson’s film interpretation of J.R.R. Tolkien’s The Lord of the Rings is its use of fantasy to inspire a “recovery” of the actual or, in other words, a reawakening to the beauty of nature and the many possible ways of living in healthier ecological relation to the world. Though none of these ways is perfectly achieved, this pluralistic view is demonstrated in the various lifeways of Hobbits, Elves, Men, and Ents. All of the positive (...) relationships embodied in the films—to trees, mountains, horses, and vegetable gardens—involve loving care and attention, receiving nourishment and livelihood without instrumentalization, or reducing nature to mere resource. The films also vividly display a variety of ugly and destructive ways of using the land to accrue power and wealth. These noxious ways, specifically because they actively destroy the lands that they use, always need more. They will thus eventually annihilate the beautiful ways of being if they are not actively resisted. Some of those who would rather be tending their own trees, gardens, or horses or even wandering in the wild forests must therefore turn their attention to struggle and resistance instead. This is a struggle full of grief, and at times even verging on despair, but it is marked by the refusal to give up hope. Indeed, what Jackson and Tolkien have to say about hope is as important in responding to the ecological crisis as anything they have to say about nature, inasmuch as they help to remind us that even in our own times, “there is still hope.”.

In recent years, there has been a heated debate about how to interpret findings that seem to show that humans rapidly and automatically calculate the visual perspectives of others. In the current study, we investigated the question of whether automatic interference effects found in the dot-perspective task (Samson, Apperly, Braithwaite, Andrews, & Bodley Scott, 2010) are the product of domain-specific perspective-taking processes or of domain-general “submentalizing” processes (Heyes, 2014). Previous attempts to address this question have done so by implementing inanimate (...) controls, such as arrows, as stimuli. The rationale for this is that submentalizing processes that respond to directionality should be engaged by such stimuli, whereas domain-specific perspective-taking mechanisms, if they exist, should not. These previous attempts have been limited, however, by the implied intentionality of the stimuli they have used (e.g. arrows), which may have invited participants to imbue them with perspectival agency. Drawing inspiration from “novel entity” paradigms from infant gaze-following research, we designed a version of the dot-perspective task that allowed us to precisely control whether a central stimulus was viewed as animate or inanimate. Across four experiments, we found no evidence that automatic “perspective-taking” effects in the dot-perspective task are modulated by beliefs about the animacy of the central stimulus. Our results also suggest that these effects may be due to the task-switching elements of the dot-perspective paradigm, rather than automatic directional orienting. Together, these results indicate that neither the perspective-taking nor the standard submentalizing interpretations of the dot-perspective task are fully correct. (shrink)
