It is shown that Einstein abandoned his earlier view that there are material consequences, such as asymmetric aging, implied by the space-time transformations of transformations of relativity theory.

The most general expression of electromagnetic theory is examined in the light of (1) Faraday's interpretation of the field as a potentiality for the force of charged matter to act upon a test body, and (2) Einstein's view of the field equations as an example of a covariant expression of special relativity. Faraday's original interpretation, in which all physical variables must be expressible as nonsingular fields, implies a particular generalization of the standard forms of the conservation equations and leads to (...) a removal of the problem of the infinite self-energy of point sources. A further generalization of the mathematical expression of electromagnetism occurs when it is asserted that the form of the laws must be compatible with the symmetry requirements of the irreducible representations of the Poincaré group. This yields a factorization of the vector field equations, giving a set of two uncoupled two-component spinor equations. It is shown that the latter lead to twice as many conservation equations for electromagnetism, compared with the vector formalism, thus making extra predictions that are not made in the latter formalism. It is shown that the extra conservation equations reveal themselves only when incorporating the requirements of Faraday's interpretation of the field solutions. (shrink)

The first part of this paper examines conditions in accord with Einstein's criterion of regularity on the field solutions everywhere that would correspond to the existence of a black hole star, following from solutions of his (nonvacuum) field equations. ‘Black hole’ is defined here as a star whose matter is so condensed as to correspond to a complete family of spatially closed geodesics. The condition imposed is that the angular momentum of a test body in each of the closed geodesics (...) is a constant of the motion. The second part of the paper examines the implications in the problem of the condensed star of a generalized (factorized) version of the metrical field equations, discovered earlier by the author. It is found that in general relativity stars should naturally pulsate, and in its succeeding cycles the gravitational radius of the star is attenuated by a factor exp(−0.349T), where T is the pulsation period. Conditions are discussed for the possibility that the (relatively) regular emissions of radiation from a pulsar may be dynamically rooted in a (smaller) part of the pulsation cycle when the star is out of the black hole state (less dense → open geodesics)—when radiation would be emitted to the outside world—and the (greater) part of the cycle when it is in the black hole state (more dense → closed geodesics)—when radiation would not be emitted.

This paper presents a qualitative comparison of opposing views of elementary matter—the Copenhagen approach in quantum mechanics and the theory of general relativity. It discusses in detail some of their main conceptual differences, when each theory is fully exploited as a theory of matter, and it indicates why each of these theories, at its presently accepted state, is incomplete without the other. But it is then argued on logical grounds that they cannot be fused, thus indicating the need for a (...) third revolution in contemporary physics. Toward this goal, the approach discussed is one of further generalizing the theory of general relativity in a way that incorporates the inertial manifestations of matter in covariant fashion, with quantum mechanics serving as a low-energy, linear approximation. Such a theoretical extension of general relativity will be discussed, with applications in elementary particle physics, such as the appearance of mass spectra in the microdomain, as an asymptotic feature of matter, mass doublets (electron-muon and proton-heavy proton), the explanation of pair annihilation and creation from a deterministic field theory, charge quantization, and features of pions.

This paper responds briefly to the criticism of Rodrigues and Rosa on my earlier analysis of the twin paradox. The main point that I have emphasized (and that the authors have not refuted, either logically or mathematically) is the error in directly identifying anabstract measure relative to a reference frame [and its transformations to all other possible reference frames in which the laws of nature are to be compared (such as temporal and spatial measures)], with aphysical extension and duration of (...) a material body.

The precessional frequency of a gyroscope in a reference frame that orbits about a gravitational body is compared between Einstein's tensor formulation of general relativity and the author's quaternion generalization—obtained from a factorization of the tensor form. The difference in predictions then suggests an experiment that could choose which of these formulations of general relativity is more valid in the analysis of gyroscopic motion.

Myth, Utopia, and Political Action Starting from the premise that some form of "reality transcendence", i.e. the ability to imagine a different reality and reach out for the (un)thinkable, is necessary for political action, the aim of this paper is to analyse the concepts of myth and utopia elaborated by Georges Sorel and Karl Mannheim and to examine their possible contributions to a theory of political action and social change. By comparing the role the authors assign to rationality and irrationality (...) in human affairs, methodological and conceptual differences between Sorel's and Mannheim's approaches to the political are illustrated. It turns out that due to its immunity to critique Sorel's concept of the social myth is highly problematic. Mannheim's concept of utopia, on the other hand, culminates in a technocratic understanding of the political. Though both approaches emphasise the collective dimension of political action, they ultimately exhibit elitist understandings of the political. (shrink)

Following the practice of human beings everywhere historians distinguish the real or most significant cause of an occurrence or state of affairs from ‘less important considerations’, ‘precipitating circumstances’, or ‘mere conditions’. I shall term claims that some phenomenon is most basically to be attributed to some one of the factors causally necessary for its occurrence attributive causal explanations or causal attributions and discuss here the extent to which moral convictions are constitutive of them.

The author argues, Contra hume, That "the motives of human action are not related to the action in the way in which the causes of the sort of physical behaviour to which hume refers are related to that behaviour." the author contends this because he is opposed to the consequence of hume's theory that "moral appraisal presupposes 'necessity' or determinism." he concludes that we do have to explain morality in terms of human motives, But that a different sort of causality (...) is involved here than in the physical world.

This is an English translation of four of Plato’s dialogue (Protagoras, Euthydemus, Hippias Major, and Cratylus) that explores the topic of sophistry and philosophy, a key concept at the source of Western thought. Includes notes and an introductory essay. Focus Philosophical Library translations are close to and are non-interpretative of the original text, with the notes and a glossary intending to provide the reader with some sense of the terms and the concepts as they were understood by Plato’s immediate audience.

Esta pesquisa teve como objetivo analisar o conhecimento teórico de conselhos tutelares sobre o Estatuto da Criança e do Adolescente e suas atuações a partir disso. Para isso, realizamos entrevistas com dois conselhos por meio de um questionário. As respostas foram dadas por escrito e, com elas, pudemos notar convergências e divergências entre esses conselhos. Com a análise, percebemos que cada conselho possui um olhar no seu trabalho, porém ambos possuem consciência de que seu dever é o de proteger e (...) garantir os direitos das crianças e dos adolescentes. Ambos os conselhos admitiram existir interação com a escola, porém, ela se restringe ao controle de frequência e da evasão escolar. Também, ambos remetem casos de violação de direitos à realidade social, afirmando que fatores econômicos não são determinantes nesses atos, porém, nos casos de famílias em situações econômicas desfavoráveis, o conselho tutelar é acionado. Por fim, enquanto um dos conselhos diz que aquele que viola algum direito da criança ou do adolescente deve ser responsabilizado, outro afirma que ele deve intervir com medidas educativas para resgatas a proteção do menor. Concluímos que os conselhos conhecem seus deveres, porém deixam a desejar no que tange à relação com as escolas. (shrink)

In November 2008 Professor Mike Richards issued his much awaited review of the British Department of Health's policy on out-of-pocket payments for drugs not approved as cost effective by the National Institute for Health and Clinical Excellence. The policy stated, or had been construed as stating, that those who top up thereby became ineligible for further National Health Service treatment for the condition targeted by the drug. For instance, if a lung cancer sufferer bought Avastin, which is not NICE approved, (...) she could no longer receive free treatment for her cancer on the NHS's tab. Richards, the National Cancer Director, recommended that the policy be repealed. From an ethical point of view, this change should be enthusiastically welcomed. (shrink)

It is commonly held that moral judgements are implicitly general — or universalizable — in that if anyone is morally obligated to perform or refrain from some action, everyone in relevantly similar circumstances is similarly obligated. I undertake here to show that David Hume fully subscribed to this thesis and that because of the way it is related to his conceptions of obligation and what he terms the practicality of morals he is pushed to insist that the moral sentiments of (...) human beings across space and time are much more uniform than he knew them to be. My discussion places Hume in the historical context of the controversy about 'the general foundation of morals' referred to near the beginning of the second Enquiry, and it is part of my thesis that Hume's moral philosophy can be understood only in terms of arguments and counter-arguments developed by other contributors to the controversy.

Seit ihrer Begründung im 18. Jahrhundert war die Ästhetik auch ein Korrektiv der Logik, indem sie die Sinnlichkeit des Menschen - Wahrnehmungen, Gefühle, Erinnerungen sowie deren Ausdruck in Kunst, Literatur und Wissenschaft - in den Blick genommen hat. In diesem Band wird die Vielfalt ästhetischer Perspektiven dokumentiert: Als Gesellschaftskritik und Erkenntnistheorie, als Lehre vom Schönen und Theorie der Kunst ist die Ästhetik nicht wegzudenken, wenn man den Menschen in seiner kulturellen Existenz begreifen möchte.
