© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

Chauncey Wright (1830–1874) was one of the first American philosophers to explore the implications of Charles Darwin's work in evolutionary biology. Wright became a strong supporter of the idea of natural selection and a strong critic of the anti-selectionist and teleological arguments of St. George Jackson Mivart and Herbert Spencer, and he laid the groundwork for the field that is today called evolutionary epistemology. As the mentor of the original Cambridge "Metaphysical Club" (William James, Charles Sanders Peirce, and Oliver (...) Wendell Holmes, Jr.), Wright was also instrumental in the development of the American school of Pragmatism. Although his analytical brilliance was widely acknowledged, he never became professionally successful, and he died in 1874 in his 45th year. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Plotinus and the Parmenz'des B. DARRELL JACKSON IN 1928 E. R. DODDSARGUED that the first two hypotheses of Plato's Parmenides are the primary source of Plotinus' doctrines of the One and of Nous. I Dodds' main evidence was a list of parallels between the Parmenides and the Enneads? He argued further that the Neoplatonic interpretation of the Parmenides as positive metaphysics was neo-Pythagorean in origin. Several Plotinus scholars (...) have accepted and extended Dodds' view of the importance of the Parmenides for Plotinus. This group includes ]~mile Br6hier, ~ A. H. Armstrong, 4 Hans-Rudolf Schwyzer, 5 and Paul Henry. n But Dodds' position is by no means universally accepted. Elmer O'Brien has recently argued that the Plotinian One was derived ultimately from Philo and mediated to Plotinus through Albinus and Numenius. 7 He says that Dodds' case, though good, is not convincing. It. A. Wolfson has been the great advocate of the Philonic origin of Plotinus' views. According to Wolfson, the doctrines attributed by Plotinus to Plato are not Plato's but mainly Philo's. 8 Others see Plotinus in varying degrees of dependence upon Plato. Philip Merlan holds that Plotinus is more in debt to the immediate successors of Plato and to Aristotle's interpretation of Plato than to the Platonic writings themselves. 9 C. J. de Vogel sees Plotinus as dependent upon Plato for a hierarchy of being which was accepted and elaborated by various middle Platonists and Gnostics. 1~According to de Vogel, the Parmenides wus not importan% in this hierarchy tradition, n In this article I shall re-examine Dodds' position. I believe the case for Plotinus' dependence upon the Parmenides can be strengthened. I shall try to do this by examining the systematic relation of Plotinus' thought to the Parmenides.

[3]5] 316 HISTORY OF PHILOSOPHY considered only parallel terminology. I shall in addition look at parallel argumentation and conclusions. Furthermore, since Dodds accounts only for Plotinus' first two hypostases, I shall consider the relation of the third hypostasis (soul) to the Parmenides. My primary interest is not the source of Plotinus' interpretation of the Parmenides but the way he carries that interpretation out. TM The former issue has often been focal in the literature on this subject. ~8It is certain thay many of the ideas used by Plotinus were already in circulation. But it is equally certain that in his combination of these ideas of a hierarchy, of transcendence, etc., Plotinus is original. I shall argue that this originality of combination is largely determined by an interpretation of the Parmenides. I should add that I am not concerned with whether Plotinus' interpretation is correct. ~4 In the following pages I shall attempt to show three things: (1) how Plotinus explicitly interprets the Parmenides, (2) to what extent he draws upon the language of the Parmenides, and (3) to what extent Plotinus' system may be understood by its relation to the Parmenides. I. Plotinus' Interpretation of the Parmenides The obvious place to begin an analysis of Plotinus' relation to the Parmenides is Enneads V... (shrink)

The essays in this volume explore current work in central areas of philosophy, work unified by attention to salient questions of human action and human agency. They ask what it is for humans to act knowledgeably, to use language, to be friends, to act heroically, to be mortally fortunate, and to produce as well as to appreciate art. The volume is dedicated to J. O. Urmson, in recognition of his inspirational contributions to these areas. All the essays but one have (...) been specially written for this volume. (shrink)

The problem to be discussed here concerns ontology so far as it may not be formed by scientific theory. In brief terms, the problem arises in the following way. On the one hand, the world surely consists of whatever is there, irrespective of whether human beings are around or not, and irrespective especially of whether human beings have constructed any scientific theories depicting the nature of the world; on the other hand, scientific theories are subject to the limitation that we (...) can never verify them or prove them to be true, so that the ontology prescribed by scientific theory is not firmly established but is only what is attributed to the world by a fallible scientific theory at any given time. The problem could also be put in terms of ‘conceptual networks’ or in terms of language-systems. (shrink)

This article discusses two interpretations of musical harmony around the 3rd century BCE based on the Xunzi 荀子 and the Lüshi Chunqiu 呂氏春秋, comparing the concepts of resonance between sound and qi 氣 in each interpretation. The Xunzi supports the moral influence of the sage kings’ music where ethical resonance between sound and bodily qi serves as firm ground for musical harmony begetting social harmony. In contrast, the Lüshi Chunqiu advocates the idea of physical resonance between sound and cosmic qi (...) whereby musical harmony acts as a contributor to cosmic harmony. In discussing resonance between sound and qi, the Xunzi restricts its scope to the human realm while the Lüshi Chunqiu extends it more broadly to the cosmic realm, which indicates that humans foster cosmic harmony. This broader perspective is an adequate reflection of the germinating idea of a resonant correlation between the human and cosmic realms. (shrink)

The paper contains a philosophically examinesation of the notion of the common good. The major point argued is that the common good, contrary to the way it isits traditionally definedition in political philosophy, need not be communitarian alone, itbut couldan also be liberal. The paper juxtaposes the normative liberal idea of liberty to the communitarian notion of the common good. The conclusion is that the liberal notion of liberty couldan serve the common good, especially in a liberal society. Theis idea (...) of liberal liberty is not antithetical to the common good.

Philosophical Analysis Its Development between the Two World Wars.

Instrumentalism is an approach to science that treats a theory as a tool and only as a tool for computation; it dispenses with the concept of truth.Conventionalism treats a theory as true by convention if it forms a pattern of observations from which correct predictions can be made.Operationalism denies meaning to the concepts of a theory unless they can be defined operationally. It is argued in this paper that truth-value is indispensable to science, because a theory can be rejected only (...) if an empirical consequence is false and if falsity of a conclusion entails falsity of a premise. This undermines the above positions. The fourth interpretation isinduction. Induction, by contrast, uses the notion of truth-value. What is focused on here is its reliance on the ultimacy ofobservation. The present thesis is that instrumentalism, conventionalism, and induction are different attempts to handle observations. The common problem is the gap between data and theory.All these interpretations share a philosophy of observationalism. The aim of this paper is to show that the several orthodox interpretations of science all fail to solve the problem of the data-theory gap, and to show that they all presuppose a philosophy of observation.

The schema, or theoretical framework, holism, is concerned with the essence of society as a whole. Though undermined by Popper, it cannot be refuted ? nor proved. The extreme alternative is individualism. Several forms, due to Freud, Wittgenstein, and phenomenology, make presuppositions that require the individualist interpretation of society to be reopened at a new point. Popper's ? or Weber's ? is the sturdiest; its units being individual actions plus their unintended by?products. The Weber?Popper schema can provide a framework for (...) many satisfactory societal explanations. But individualism misses the holistic possibility of dynamic societal forces; the individualist fails to produce any dynamic laws. A dynamic bipolar schema could put both schemata to work without prescribing which would predominate. Empirical investigation would determine the more fruitful for a given problem. This schema would be ?justified? by fostering a satisfactory empirical social theory. The present investigation also reveals where the real controversies about schemata lie. (shrink)

Some twenty different background approaches, or schemata, permeate the social sciences. Most of their exponents regard their choice as excluding the rest. This paper is concerned to show that all such conflict is merely disputatious since virtually all the schemata require one another. Taking the individual's need to act as starting-point, certain restrictions limiting his freedom of action are identified as factors of the overt societal situation. These, however, fail to explain all aspects of his powerlessness, to account for which (...) he then seeks such deeper constraints as unseen powers or human conspiracies. Social scientists for their part develop theories or interpretations of the societal situation. The paper turns to the first of three groups of interpretations, concentrating on one constituent of the group, functionalism, which is a mirror-image of another constituent, 'conflict theory'. The complementarity of these two is claimed to apply to virtually all the schemata considered. (The second and third groups are deferred to the sequel.) The Appendix deals with the way in which explanatory factors can be combined. Having removed the unreal contentions associated with various schemata, the way is clear to treatment of the one substantive issue among them - to do with holism - in the sequel. (shrink)
