By means of a Clebsch representation which differs from that previously applied to electromagnetic field theory it is shown that Maxwell's equations are derivable from a variational principle. In contrast to the standard approach, the Hamiltonian complex associated with this principle is identical with the generally accepted energy-momentum tensor of the fields. In addition, the Clebsch representation of a contravariant vector field makes it possible to consistently construct a field theory based upon a direction-dependent Lagrangian density (it is this kind (...) of Lagrangian density that may arise when developing the Finslerian extension of general relativity). The corresponding field equations are proved to be independent of any gauge of Clebsch potentials. The law of energy-momentum conservation of the field appears to be covariant and integrable in a rather wide class of direction-dependent Lagrangian densities. (shrink)

A Finslerian extension of general relativity is examined with particular emphasis on the Finslerian generalization of the equation of motion in a gravitational field. The construction of a gravitational Lagrangian density by substituting the osculating Riemannian metric tensor in the Einstein density is studied. Attention is drawn to an interesting possibility for developing the theory of test bodies against the Finslerian background.

The analysis of a previous paper (see Ref. 1), in which the possibility of a Finslerian generalization of the equations of motion of gravitational field sources was demonstrated, is extended by developing the Finslerian generalization of the gravitational field equations on the basis of the complete contractionK = K lj lj of the Finslerian curvature tensorK l j hk (x, y). The relevant Lagrangian is constructed by the replacement of the directional variabley i inK by a vector fieldy i (x), (...) so that the notion of osculation may be regarded as the key concept on which the approach is based. The introduction of the auxiliary vector fieldy i (x) is shown to be of physical significance, for the field equations refer not only to the proper field variables but also to a special coordinate system associated withy i (x) through the Clebsch representation of the latter. The status of the conservation laws proves to be similar to that in the theory of the Yang-Mills field. By choosing a special Finslerian metric function we elucidate in detail the structure of the field equations in the static case. (shrink)

The degree of success in creating quality care for people suffering from dementia is limited despite extensive research. This article describes Healthcare providers’ experience with the ethical challenges and possibilities in the relationship with patients suffering from dementia and its impact on quality care. The material is based on qualitative, in-depth individual narrative interviews with 12 professional Healthcare providers from two different nursing homes. The transcribed interview texts were subjected to a phenomenological–hermeneutical interpretation. To provide quality care to patients with (...) dementia, the Healthcare providers emphasized the importance of sensing and understanding the patients’ emotional and bodily expressions through sentient attentiveness and recognition of the patient as a person. They also described reciprocity of expressions in the relationship where the patient recognized them both as persons and Healthcare providers. The analyses of the findings are, inter alia, discussed in light of Løgstrup’s relational philosophy of ethics. (shrink)

This article deals with four almost classic problems in Anaximander. of these the first is of comparatively minor importance, and the second is important not for what Anaximander thought but for what Aristotle thought he thought. Problem i is: Did Anaximander describe his as ? Problem 2: Did Aristotle mean Anaximander when he referred to people who postulated an intermediate substance ? Problem 3: Did Anaximander think that there were innumerable successive worlds? Problem 4: What is the extent and implication (...) of the extant fragment of Anaximander? Appended is a brief consideration of the nature of Theophrastus' source-material for Anaximander; on one's opinion of this question the assessment of the last two problems will clearly depend.

This work provides a text and an extended study of those fragments of Heraclitus' philosophical utterances whose subject is the world as a whole rather than man and his part in it. Professor Kirk discusses fully the fragments which he finds genuine and treats in passing others that were generally accepted as genuine but here considered paraphrased or spurious. In securing his text, Professor Kirk has taken into account all the ancient testimonies, and in his critical work he attached particular (...) importance to the context in which each fragment is set. To each he gives a selective apparatus, a literal translation and and an extended commentary in which problems of textual and philosophical criticism are discussed. Ancient accounts of Heraclitus were inadequate and misleading, and as Kirk wrote, understanding was often hindered by excessive dogmatism and a selective use of the fragments. Professor Kirk's method is critical and objective, and his 1954 work marks a significant advance in the study of Presocratic thought. (shrink)

Popper proposes a technical concept of 'verisimilitude' as a test of the progressiveness of scientific theories. The paper attempts to show its uselessness and inapplicability on mathematical and practical grounds, As well as raising doubts about the value of any such attempt to give a mechanical test of scientific progress.

I present the current experimental and theoretical work on interference in complementary spaces. These ideas are applicable to both light and matter waves. I give a detailed treatment for classical light beams in frequency and time domains. I also present a description which gives the totality of interferences.

The present and future rapid increase in the hospital population of geriatric patients is discussed with particular reference to the problem of advanced brain degeneration. The consequences of various clinical management options are outlined and it is suggested that extreme attempts either to preserve or terminate life are medically, morally and socially unacceptable. The preservation of life in senile patients has important economic consequences. In achieving a decision on the medical management of patients with advanced brain decay it is suggested (...) that substantial help would be derived from: knowledge of the previously declared wishes of individual patients; improvements in geriatric assessments; broader consultation with relatives, and greater use of inter-disciplinary discussion in the preparation of criteria for terminating medical efforts to maintain survival.

Professor Peter Bodunrin's paper ‘The Question of African Philosophy’ 161–179) has, as it were, become the first question for most African scholars, teachers or students, starting a course in African philosophy. In most of the discussions, the controversy over what constitutes an African philosophy tends to dominate, sometimes so much that it forms almost the entire content of the course.

In the sixties I attempted to comprehend the Zen paradox: 1,400 years of handing down a tradition through absurd statements. I had to construct a theory of the absurd. It led me to the conclusion that not only connections among words could be absurd ; connections among objects themselves could also be absurd. God hung on the cross seemed an absurdity. The Apostle Paul acutely felt this absurdity, and later Tertullian felt it even more acutely. A thousand years later, for (...) Aquinas, the sense of absurdity had subsided, and the diminution of God to the "perspective of the slave" became a postulate of scholastic reason. In all transitional periods, when the "world is out of joint," a palpably absurd situation arises, and grotesque, absurd literature is created. François Villon became popular in Russia in the twentieth century, not very long before Kafka; the poem written for the contest in Blois engraved itself in my memory. The poem is rational in its own way, i.e., it describes well the realities of life itself. (shrink)

Philosophical anthropologist Mircea Eliade once said that "the union of opposites" is a basic category of archaic ontology and comparative world religions. In this paper I develop the theory of contrariety or opposition as a prime focus for East/West comparative philosophy. The paper considers especially Nishida Kitaro's later works and the complex phrase "zettai mujuntekijikodbitsu," variously translated by Schinzinger as "absolute contradictory self-identity," "the self-identity of absolute contradictories," or more simply as "oneness" or "unity" of opposites.

We propose partial measurements as a conceptual tool to understand how to operate with counterfactual claims in quantum physics. Indeed, unlike standard von Neumann measurements, partial measurements can be reversed probabilistically. We first analyze the consequences of this rather unusual feature for the principle of superposition, for the complementarity principle, and for the issue of hidden variables. Then we move on to exploring non-local contexts, by reformulating the EPR paradox, the quantum teleportation experiment, and the entanglement-swapping protocol for the situation (...) in which one uses partial measurements followed by their stochastic reversal. This leads to a number of counter-intuitive results, which are shown to be resolved if we give up the idea of attributing reality to the wavefunction of a single quantum system. (shrink)

We show that local realism applied to states characterized by a single quantum equally and coherently shared between a number of qubits (so-called W states) produces predictions incompatible with quantum theory. The origin of this incompatibility is shown to originate from the destructive interference of amplitude probabilities associated with nonlocal states, a phenomenon that has no classical analog.

During the excavations of 1924–5 at Karanis a papyrus of the second or early third century A.D. was discovered, and subsequently published by J. G. Winter , which under its single column has a subscribed title which should almost certainly be restored as ‘Alcidamas, On Homer’. The first fourteen lines of the papyrus give most of the story of Homer's death and the riddle that caused it, which is common to all the extant Lives of Homer; the remainder is a (...) general eulogy of Homer and a profession of transmitting his works to posterity. The interest of the discovery lies in the knowledge that it gives of a hitherto unrecorded work by Alcidamas, the rhetorician and contemporary of Isocrates, and the new fuel that it provides for an old controversy about the origins of the work known as the Certamen. The first part of this article aims at both re-examining the value of the papyrus and reopening some of the old questions on the Certamen. (shrink)

One of the curious things about Homeric studies is the way in which, although opinions in this field fluctuate violently, from time to time certain among them tend to become crystallized for no particular reason and are then accepted as something approaching orthodoxy. It is to try to delay such a crystallization, if it is not already too late, that I direct this brief coup d'ail at some current opinions on whether Homer—for the sake of clarity I apply this name (...) in the first instance to the monumental composer of the Iliad—used the aid of writing, and in general at the value of comparative inferences based on the heroic poetry of modern Yugoslavia.
