    On the Two Aspects of Time: The Distinction and its Implications. [REVIEW]L. P. Horwitz, R. I. Arshansky & A. C. Elitzur - 1988 - Foundations of Physics 18 (12):1159-1193.
    The contemporary view of the fundamental role of time in physics generally ignores its most obvious characteric, namely its flow. Studies in the foundations of relativistic mechanics during the past decade have shown that the dynamical evolution of a system can be treated in a manifestly covariant way, in terms of the solution of a system of canonical Hamilton type equations, by considering the space-time coordinates and momenta ofevents as its fundamental description. The evolution of the events, as functions of (...)

    Selection Rules for Dipole Radiation From a Relativistic Bound State.M. C. Land, R. I. Arshansky & L. P. Horwitz - 1994 - Foundations of Physics 24 (4):563-578.
    Recently, in the framework of a relativistic quantum theory with invariant evolution parameter, solutions have been found for the two-body bound state, whose mass spectrum agrees with the nonrelativistic Schrödinger energy spectrum. In this paper, we study the radiative transitions of these states in the dipole approximation and find that the selection rules are identical with those of the usual nonrelativistic theory, expressed in a manifestly covariant form. In addition to the transverse and longitudinal polarizations of the nonrelativistic theory, we (...)

    Off-Shell Electromagnetism in Manifestly Covariant Relativistic Quantum Mechanics.David Saad, L. P. Horwitz & R. I. Arshansky - 1989 - Foundations of Physics 19 (10):1125-1149.
    Gauge invariance of a manifestly covariant relativistic quantum theory with evolution according to an invariant time τ implies the existence of five gauge compensation fields, which we shall call pre-Maxwell fields. A Lagrangian which generates the equations of motion for the matter field (coinciding with the Schrödinger type quantum evolution equation) as well as equations, on a five-dimensional manifold, for the gauge fields, is written. It is shown that τ integration of the equations for the pre-Maxwell fields results in the (...)

    Particles Vs. Events: The Concatenated Structure of World Lines in Relativistic Quantum Mechanics. [REVIEW]R. Arshansky, L. P. Horwitz & Y. Lavie - 1983 - Foundations of Physics 13 (12):1167-1194.
    The dynamical equations of relativistic quantum mechanics prescribe the motion of wave packets for sets of events which trace out the world lines of the interacting particles. Electromagnetic theory suggests thatparticle world line densities be constructed from concatenation of event wave packets. These sequences are realized in terms of conserved probability currents. We show that these conserved currents provide a consistent particle and antiparticle interpretation for the asymptotic states in scattering processes. The relation between current conservation and unitarity is used (...)

    Coevolution of Neocortical Size, Group Size and Language in Humans.R. I. M. Dunbar - 1993 - Behavioral and Brain Sciences 16 (4):681-694.
    Group size is a function of relative neocortical volume in nonhuman primates. Extrapolation from this regression equation yields a predicted group size for modern humans very similar to that of certain hunter-gatherer and traditional horticulturalist societies. Groups of similar size are also found in other large-scale forms of contemporary and historical society. Among primates, the cohesion of groups is maintained by social grooming; the time devoted to social grooming is linearly related to group size among the Old World monkeys and (...)

    The Theoretical Practices of Physics: Philosophical Essays.R. I. G. Hughes - 2009 - Oxford University Press.
    R.I.G. Hughes presents a series of eight philosophical essays on the theoretical practices of physics. The first two essays examine these practices as they appear in physicists' treatises (e.g. Newton's Principia and Opticks ) and journal articles (by Einstein, Bohm and Pines, Aharonov and Bohm). By treating these publications as texts, Hughes casts the philosopher of science in the role of critic. This premise guides the following 6 essays which deal with various concerns of philosophy of physics such as laws, (...)

    Resource Competition and Reproduction.Eckart Voland & R. I. M. Dunbar - 1995 - Human Nature 6 (1):33-49.
    A family reconstitution study of the Krummhörn population (Ostfriesland, Germany, 1720–1874) reveals that infant mortality and children’s probabilities of marrying or emigrating unmarried are affected by the number of living same-sexed sibs in farmers’ families but not in the families of landless laborers. We interpret these results in terms of a “local resource competition” model in which resource-holding families are obliged to manipulate the reproductive future of their offspring. In contrast, families that lack resources have no need to manipulate their (...)

    First-Order Definability in Modal Logic.R. I. Goldblatt - 1975 - Journal of Symbolic Logic 40 (1):35-40.
    It is shown that a formula of modal propositional logic has precisely the same models as a sentence of the first-order language of a single dyadic predicate iff its class of models is closed under ultraproducts. as a corollary, any modal formula definable by a set of first-order conditions is always definable by a single such condition. these results are then used to show that the formula (lmp 'validates' mlp) is not first-order definable.

    Thucydides 3.12.3.R. I. Winton - 1998 - Classical Quarterly 48 (01):294-.
    The Oxford text of this passage reads as follows:This gives the received text and punctuation. No generally agreed meaning has been found in the opening sentence as it thus stands; nor have any of the numerous alternative versions which have been proposed gained widespread support. In this paper I suggest that good sense can, after all, be made of this passage in its received form.

    Thucydides 2.35 and 45.2: Against Praise.R. I. Winton - 2010 - Journal of Hellenic Studies 130:153-163.
    This paper suggests that two much-discussed passages in Pericles' Funeral Speech in Thucydides Book 2, the first in 2.35.2, the second in 2.45.2, are more closely related than has previously been recognized: both express a negative view of praise - praise of the fallen; and of their widows. It proposes new interpretations of the passages in question: in the first sentence of 35.2 Pericles is contrasting the splendour of the funeralceremonywith the necessary restraint of a funeralspeech; in the second sentence (...)

    On the Identification of the Soma/Haoma Plant.R. I. Zaguidoullin - 2008 - Proceedings of the Xxii World Congress of Philosophy 50:907-912.
    During the second half of the XX century drug addiction ceased to be only the epiphenomenon of crime, prostitution and a number of other social-relations deviation, and became a constant value of post-industrial society and at the end of XX century turned into a global problem of mankind. A new form of mass neurosis shows that drug dependence is nowadays socially conditioned mental degeneration, caused by activation of unconscious collective archetypes that are experienced depending on the corresponding situation. The identification (...)

    Data on the number of adults that an individual contacts at least once a month in a set of British populations yield estimates of network sizes that correspond closely to those of the typical “sympathy group” size in humans. Men and women do not differ in their total network size, but women have more females and more kin in their networks than men do. Kin account for a significantly higher proportion of network members than would be expected by chance. The (...)

    Size and Structure of Freely Forming Conversational Groups.R. I. M. Dunbar, N. D. C. Duncan & D. Nettle - 1995 - Human Nature 6 (1):67-78.
    Data from various settings suggest that there is an upper limit of about four on the number of individuals who can interact in spontaneous conversation. This limit appears to be a consequence of the mechanisms of speech production and detection. There appear to be no differences between men and women in this respect, other than those introduced by women’s lighter voices.

    Utilitarianism: The Classical Principle and the Average Principle.R. I. Sikora - 1975 - Canadian Journal of Philosophy 5 (3):409 - 419.
    Act Utilitarianism has traditionally been regarded as the view that you should always perform the action that will bring about the greatest possible excess of happiness over unhappiness or, if there is no such alternative, the least possible excess of unhappiness over happiness.1 Following Rawls, I shall call this the classical principle. An alternative which Rawls calls the average principle is the view that you should always do the thing that will bring about the highest possible average happiness level. Rawls, (...)

    Utilitarianism, Supererogation and Future Generations.R. I. Sikora - 1979 - Canadian Journal of Philosophy 9 (3):461 - 466.
    I shall argue here that the reason supererogatory acts are not obligatory is that they require too much personal sacrifice, and that in order for an act to be supererogatory, it must have a kind of result that you would have an obligation to bring about if you could do so with no personal sacrifice. I further argue that traditional utilitarianism should be modified so as not to treat supererogatory acts as obligatory.

    Symmetry Arguments in Probability Kinematics.R. I. G. Hughes & Bas C. van Fraassen - 1984 - PSA: Proceedings of the Biennial Meeting of the Philosophy of Science Association 1984:851-869.
    Probability kinematics is the theory of how subjective probabilities change with time, in response to certain constraints . Rules are classified by the imposed constraints for which the rules prescribe a procedure for updating one's opinion. The first is simple conditionalization , and the second Jeffrey conditionalization . It is demonstrated by a symmetry argument that these rules are the unique admissible rules for those constraints, and moreover, that any probability kinematic rule must be equivalent to a conditionalization preceded by (...)
