© 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)

The title essay was originally presented as two lectures inaugurating the John Dewey lectures at Columbia. It is an important essay for understanding Quine's work for it brings together many themes at the center of his thinking since Word and Object. Quine quotes with approval Dewey's statement "meaning is primarily a property of behavior" and then goes on to consider a thesis which, according to Quine, is a consequence of such a behavioral theory of meaning, i.e., the thesis of the (...) indeterminacy of meaning and translation. Quine relates this indeterminacy thesis, which he has been defending for some time, to language learning, the foundations of mathematics, and to a general view of ontological relativity. Other essays in the volume concern natural kinds and the various paradoxes of confirmation, propositional objects, quantification and existence and the empirical basis of science. All the essays are post-1965 except the introductory essay which was Quine's Presidential Address to the Eastern Division of the American Philosophical Association in 1956. This address was something of an introduction to the ideas to appear in Word and Object and is placed at the beginning of this collection to emphasize that all the essays collected here expand on and defend some of the positions of Word and Object. Quine's fluid style is everywhere in evidence.--R. H. K. (shrink)

Three short essays on the position of the philosopher and philosophy in modern society. Maritain illuminates the situation of the philosopher in a milieu of conflicting systems. The final essay, which deals with the relation of science and religion, shows evidence of a growing appreciation by Maritain of the aims of modern science.--R. H. K.

Leibniz' General Investigations, a group of memoranda on logical and methodological matters, remained unpublished until Couturat published the original Latin manuscript in 1903. Only after 1960 was a German translation made by F. Schmidt and an English translation by G. H. R. Parkinson. The present translation provides extensive reference notes to Leibniz' other manuscripts, and a commentary and notes to the text. In these respects it has some advantages over previous translations. The translation is clear although the work itself is (...) sometimes difficult to follow and the notes are most welcome. An introduction discusses the place of the General Investigations within the context of Leibniz' thought. With the interest in Leibniz' logical writings very strong at present, this new translation and commentary is most welcome.--R. H. K. (shrink)

Peter Geach brings the same careful attention to logical detail to these studies in the philosophy of religion and philosophy of mind as he has brought to other philosophical works. Some of the topics discussed here, however, will surprise some readers of Geach's earlier works, e.g., reincarnation, immortality, creation, praying for things to happen, and worshipping the right God. There are separate chapters on these topics as well as chapters on thought, form and existence, and the moral law. It should (...) be noted for readers who may not share Geach's interest in some of these topics that each of the chapters makes important points about issues which go beyond the topics of immediate interest. For example, Geach's two chapters on reincarnation and immortality are very interesting commentaries on the problem of personal identity, and the chapter on praying for things to happen is an interesting essay on time. The chapters on existence and thought pick up themes from Geach's earlier writing on Aquinas and Frege and mental acts. The Aristotelian roots of Geach's thought are clear in these essays from his account of existence and thought to his denial of clear sense to the idea of an immortality of a separate soul or its reincarnation. There is a helpful analytical index.--R. H. K. (shrink)

Reichenbach wrote this book just after taking the first course Einstein ever taught on the theory of relativity. His important and influential work The Philosophy of Space and Time was written several years later and relied in part on the axiomatization of the special and general theories of relativity already worked out in this book. For special relativity Reichenbach divides his axioms into two sets, the light axioms which relate light signals to the topology and metric of time and space, (...) and the matter axioms which do the same for rigid rods and clocks. Thus the axioms focus on the conventions uniting theory and observation and give more insight into the physical foundations of the theory than do most axiomatizations. Reichenbach's approach has been criticized by Weyl and others, but at least some of the criticism seems to rest on a misunderstanding of what Reichenbach was attempting to do. Now that this early work has been translated into English, there is hope that it will be more widely read. There is no doubt that students of the theory or of recent philosophical discussion of space and time will profit from a careful reading of this book.--R. H. K. (shrink)

The expressed aim of Alf Ross' study is to lay the philosophical foundations for deontic logic by explicating the concepts of directive and norm. But there is a wider significance to his task, for he makes clear throughout that the concepts of directive and norm are central to a wide variety of disciplines, including moral, legal, and social philosophy, linguistics and the other social sciences. Moreover, the test of adequacy of his explications include an appeal to the usefulness the concepts (...) have, not only to the logician, but for the moral and legal philosopher and especially in the case of his account of norms, for the social scientist. He begins with a discussion of speech acts, developing a distinction between indicative and directive speech. A "directive" is defined in terms of directive speech as an action-idea conceived as a pattern of behavior in directive speech and a variety of different sorts of directives are distinguished. A "norm" is then defined as a directive which stands in a certain kind of relation to social facts and the elements of norms are discussed. Finally, Ross offers an interpretation of deontic logic as a set of postulates defining directive speech. He discusses some of the problems of interpretation although he does not make contact with some of the more recent discussion of deontic paradoxes, e.g., the paradoxes engendered by contrary-to-duty imperatives. This is an informative and thought provoking study. The writing is very clear and the reader is guided throughout by a helpful analytical index.--R. H. K. (shrink)

The virtue of this book is that it brings together in one volume discussions related to our ordinary conception of space and time on the one hand and discussions related to the conception of space and time in contemporary physical theory on the other. Thus we have discussion of the topology, metrical geometry, and tri-dimensionality of space; absolute vs. relative space; the order and direction of time in physical theory; the size and physical limits of the universe; and the beginning (...) and end of the universe in contemporary cosmological theory. But in addition there is discussion of the problems of identifying objects in space and time, including problems of personal identity, the notion of place and its relation to matter, the ordinary conception of past and future, and other topics. The author works through this maze by making use of a distinction between the necessary and contingent properties of space and time. His manner of drawing the line between the necessary and contingent is surely the most controversial aspect of his book. Certain cosmological theories, for example, are ruled out on logical grounds despite the fact that they may be compatible with general relativity. But the author's arguments are challenging and are backed up by an extensive knowledge of contemporary physical theory as well as of recent philosophical discussion of space and time in the English speaking world.--R. H. K. (shrink)

A book which attempts to introduce the reader to current problems in the philosophy of science, and at the same time to provide a new and significant treatment of some of these problems. The "modest empiricism" which Scheffler has espoused in a number of previous publications is given a detailed presentation in a study of historical attempts to provide meaning for three crucial concepts in the field: explanation, signification and confirmation.--R. H. K.

This book considers some of the problems of a logical nature about reference which have troubled contemporary philosophers--particularly problems about existence, identity, and definite descriptions. It deals with five philosophers who have been especially concerned with these logical problems: Meinong, Frege, Russell, Strawson, and Quine. The pivotal chapters concern Russell's theory of descriptions and Strawson's well-known critique of that theory in his paper "On Referring." According to Linsky, some of Strawson's criticisms of Russell hit their mark; but not all of (...) them do, because Russell and Strawson turn out to have "compatible views about different subjects". Strawson is concerned with certain uses of words, Russell with propositions of certain kinds. Linsky's arguments on these matters are challenging precisely because they turn some of Strawson's own assumptions against him. But Strawsonians would surely want to carry the argument beyond this book by demanding a more thorough defense of the usefulness of introducing propositions into philosophical analysis as Russell does. Other noteworthy discussions of the book concern the consequences of Frege's semantics, substitutivity and impure reference in the chapter on Quine, and a discussion of extensionality and descriptions.--R. H. K. (shrink)

This is a translation of Jacob Klein's study "Die Griechische Logistik und die Entstehung der Algebra" which appeared in 1934-1936. His principal thesis is that the Renaissance mathematicians of the sixteenth century did not simply continue the work of the Greek and Arab mathematicians but in the process of developing ancient mathematics introduced a radically new conception of number which has since guided modern mathematical thought. The central figure in this revolution is Vieta. Klein traces the influence of Vieta's ideas (...) upon Stevin, Descartes, Wallis, and other figures of the scientific revolution, after discussing the conception of number and arithmetic in Plato, Aristotle, and other Greek sources. Persons reading this book with a primary interest in the philosophical ideas involved will be frustrated by the mass of historical detail which often obscures rather than illuminates the philosophical issues. But the book deserves its reputation as an important historical study.--R. H. K. (shrink)

A highly technical theory of visual perception is developed in the first half of this psychological study with the aid of set-theoretical symbols and a complex array of variables ranging over states of the various sub-systems of the organism related to perception. In the later chapters the author describes several new and crucial experiments favoring the theory over other theories of perception, and discusses its philosophical implications for a behavioral account of mind. Those who wade through the welter of symbols (...) will find important material for a philosophy of perception in the theory and especially in the experiments, involving externally induced environmental changes which are corrected by the behavior of the organism over a period of time. --R. H. K. (shrink)

This is a careful analytical study of some of the central concepts of contemporary political thought. In separate chapters the author deals with the concepts of liberty, loyalty, power, and tolerance, exposing in the process some of the contradictions and confusions of contemporary American liberal and conservative thought. In the first chapter, which takes its point of departure from J. S. Mill's writings on liberty and political economy, Wolff shows that conservatives and liberals in the U.S. often share common principles (...) but disagree over the relevant facts. Since he thinks liberals have usually been right about the facts they have come, in his opinion, to dominate political debates. But the principles themselves need questioning, according to Wolff, and he formulates his own alternative in a final chapter entitled "Community." His aim in this final chapter is to rehabilitate the notion of the general or public good as distinct from the sum of the private goods of individuals, without falling into the totalitarian mold of various theories of the general good during the past few centuries. His ideas are not fully worked out in this chapter but they are interesting and stimulating. The other chapters on loyalty, power, and tolerance exemplify the two virtues which the book as a whole possesses. On the one hand they contain a careful analysis of the concepts involved, and on the other hand they represent a successful attempt to relate the analysis to current political problems.--R. H. K. (shrink)

A comprehensive introduction to modal logic is long overdue and this one has many virtues. It is clearly written and should be accessible to any student who has at least one semester of basic logic and is willing to read carefully and think abstractly. The first part, on modal propositional logic, begins with a summary account of classical propositional logic, the axiomatization of Principia Mathematica being the basis for the development of modal logics throughout the book. The transition to modal (...) logic is nicely motivated by a clear presentation of intuitive notions of modality and the requirements to be included in a modal logic. Thereafter three standard systems of modal propositional logic are developed axiomatically, Feys' system T and Lewis' systems S4 and S5. The semantics for these systems is then developed in the manner of Kripke with some terminological modifications. The explanation of accessibility relations between possible worlds is made especially clear through a helpful analogy with certain sorts of games. Decision procedures and completeness proofs are then developed. A similar pattern of exposition is given to modal predicate logic in Part II, the difference being that Henkin-type methods are used in the completeness proofs. Because of the many philosophical problems raised by modal predicate logic, Part II contains more philosophical discussion than Part I. A discussion of identity and descriptions in modal predicate logic is also included. The third and final part is a survey of modal systems beginning with the Lewis' systems S1-S5 and going on to systems weaker and stronger than the Lewis' systems and others which are independent of them. Systems with alternative primitives and axiomatic bases are also discussed. A final chapter discusses the relation of Boolean algebras to modal logics and brief appendices deal with natural deduction systems of modal logic, systems of entailment, alternative notations and the semantics of Kripke and Hintikka among other topics. There are exercises at the end of each chapter. This summary suggests the merits of this introduction, its clear exposition and the enormous amount of material it brings together and summarizes.--R. H. K. (shrink)

When in 1950, the distinguished psychologist, Jean Piaget, published a book on the relation of logic and psychology, the book was severely criticized in the journal Methodos by the logician E. V. Beth. Piaget asked to get together with Beth to discuss the issues involved. The result, over 15 years later, is the present book. Beth is the author of the first half in which he defends the complete autonomy of logic in relation to psychology by means of a partly (...) philosophical, partly historical treatment of logicist, formalist, and intuitionist philosophies of mathematics. Briefly put, Beth's thesis is the now familiar one in contemporary philosophy that logic and mathematics are normative sciences, psychology is a factual science. As a consequence, Beth argues that we must renounce all "psychologism" in logic and mathematics, and all "logicism" in psychology. Piaget has come to accept these main contentions of Beth and affirms them in the second half of the volume. But Piaget is impressed by the fact that a good deal of human conceptual development must go on before human beings recognize and state normative laws of logical thought. Piaget attempts to chart this conceptual development and explain how it takes place. He attempts to show that this genetic-psychological approach to the study of logical and mathematical thought is complementary to and fully compatible with the deductive approach of the formal logician, and hence compatible with Beth's thesis about the conceptual autonomy of logic and psychology. Logician and psychologist can thus deal with the same material although their approaches are conceptually autonomous. The book repays careful reading not only for the arguments defending these challenging claims but also for many other details in both parts.--R. H. K. (shrink)

The aim of this book is to introduce the reader to some new areas of contemporary logic which generally fall under the rubric of philosophical logic. It succeeds in this task to a degree, although the chapters are for the most part adaptations of journal articles published by Rescher over the last ten years and are more self-contained than they might have been. But the book should renew interest in the problems of philosophical logic. It contains many interesting discussions and (...) a great deal of useful information. Rescher begins with chapters on modal logic which include some discussion of intuitionistic logic and the causal modalities as well as the alethic modalities. He then discusses the notion of belief as a representative notion of epistemic logic. A long chapter is devoted to a history and survey of the main systems of many valued logics. Shorter, but still substantial, chapters are devoted to the logic of existence, non-standard quantification theory, chronological or tense logic, topological or positional logic, logic of assertion and logic of preference. Still shorter chapters are given to deontic logic, probability logic, a discussion of random individuals and self-reference. An interesting final chapter provides a new "discourse on method" for the philosophical or applied logician.--R. H. K. (shrink)

Intended for students of Thomistic metaphysics, this is a companion to Smith's earlier work on Natural Theology. From the basic question of being, stated in terms of the one and the many, a consistent metaphysics is developed. Stress is put upon the questions of our knowledge and the cause of being, and the relations of metaphysics, epistemology, and theology in Thomistic philosophy. The treatments of analogy, possibility, abstraction, and the transcendentals are especially informative.--R. H. K.

In this British Academy lecture, Popper argues for a reformulation of epistemological questions. In the past we have asked for the ultimate sources of knowledge and thus begged for authoritarian answers. He charges that this question of origins is relevant to the determination of meaning but not to the determination of truth. The historical sections are often interesting in their own right, especially those on the conspiracy theory of ignorance.--R. H. K.

This book is far more than an exposition of Frege's logical system and semantic concepts, although it is that. The author puts forward the challenging thesis that in trying to cope with Russell's paradox Frege deserted principles of his system which he had relied on throughout. Sternfeld attempts to show, by offering his own interpretation of Frege's logical theory, that if Frege had relied consistently on his previously formulated logical principles, Russell's paradox would have given him no trouble. Further, he (...) uses these arguments as a basis for defending the general thesis that paradoxes and other difficulties with various logical systems can only be discussed relative to the philosophical principles underlying the logical system and adopted independently of it. While these are the most challenging of the book's theses they are not its only topics. The author seems to have read everything by and about Frege and is in control of his material. There will undoubtedly be disagreements over his interpretation of Frege because Frege did not write to make expositors happy. But all students of Frege, as well as students of the philosophy of logic and philosophy of mathematics, will find this book rewarding.--R. H. K. (shrink)

Many of the papers in this volume originated in a colloquium at the University of Western Ontario in 1967. These include a paper on the logic of norms by G. H. Von Wright, a paper on the logic of questions by L. Åqvist, a paper on the logic of belief by W. Sellars, and a paper on inductive logic by R. Ackermann. The commentaries by Anderson and Sosa have been revised for the volume and a further commentary to Ackermann's paper (...) by Wesley Salmon has been added. In addition to the colloquium papers a number of further papers are published here for the first time: J. Hintikka on the semantics of propositional attitudes, R. Hilpinen on relativized modalities, C. Harrison on the unanticipated examiner and H. Smokler and M. Rohr on confirmation and translation. The volume is completed by two papers published in Synthese and a well-known paper in modal logic by Lemmon, Meredith, Meredith, Prior, and Thomas published complete with a new postscript by Prior. Although the collection is somewhat haphazard and seems to have no unifying theme, philosophers interested in these topics in philosophical logic will be thankful for the availability of the papers, both old and new.--R. H. K. (shrink)

In an introductory sketch of history of scholastic interest in aesthetics, the author notes the reawakening of Thomistic interest in this subject since the last century. He adds, with evidence drawn from nineteenth and twentieth century works, that this interest has been accompanied by methodological confusions and a misunderstanding of the theory of beauty of St. Thomas himself. He seeks to remedy this situation with a scholarly treatment of Aquinas' theory of beauty, divided into two parts; the first a genetic (...) investigation of the development of Thomas's ideas on beauty, the second a systematic account of the mature theory. A notable attempt to develop Aquinas' ideas on this subject from the entire corpus of his writings and not merely from the Summas and one or two other major works.--R. H. K. (shrink)

Papers collected in this volume were originally presented at a symposium held at the University of Pennsylvania in December, 1968 and revised in the light of discussion at the symposium for publication. The contributors hold different views about the role played by induction in theories of knowledge and rational belief but many of the papers are conciliatory, reflecting no doubt a good deal of helpful communication at the symposium. For example, Frederic Schick's clearly written and informative lead article considers subjectivist, (...) empiricist, and pragmatist theories of rational belief, arguing that they are compatible theories relevant to different types of issues. Marshall Swain follows with an article which presents a general framework within which rules of rational acceptance can be constructed. An exchange between Isaac Levi and Richard Jeffrey shows that advocates of theories of acceptance and theories of partial belief may be defending complementary and not mutually exclusive theories. In the remaining three essays Henry Kyburg Jr., Gilbert Harman, and Keith Lehrer defend their own distinctive views about the nature of inductive inference and rational belief. Kyburg traces difficulties in some theories to the acceptance of the principle of conjunction which he rejects. Harman and Lehrer both see the relation of inductive inference to explanation as crucial to understanding the former and they develop theories along different lines which make use of this relation. A long and useful bibliography was prepared for the symposium by Ralph L. Slaght and revised for publication in the volume.--R. H. K. (shrink)

In this Eddington Memorial lecture, Von Wright distinguishes two points of view from which a logician may study time. The one focuses interest on the order of temporal events and the macro-aspect of time, its flow from an indefinitely remote past through the present to an indefinitely remote future. The other focuses attention on the micro-aspect of time, the nature of the time medium, on questions of whether time is discrete or infinitely divisible or the internal structure of limited time (...) intervals. Von Wright takes the second point of view and as a result his study of time is different in some respects than that of other contemporary tense logicians. Assuming a Tractatus type ontology of possible worlds which can be totally described by stating the existence or non-existence of all possible states of affairs, Von Wright constructs several logical systems, one of discrete time ordering, another of discrete time division. He shows the latter, which is the most important for his purposes, to be formally related to certain systems of modal logic. An interpretation of this system yields an interesting definition of continuity of change and time. The definition is interesting because of its relation to another result which he derives, namely that this definition of continuity implies that the world sometimes will have to be described as being in two contradictory states at one time, a conclusion which he relates to Hegel's philosophy. This is an original and thought provoking essay.--R. H. K. (shrink)

The author offers some interesting suggestions for the rewriting of the history of logic which modern developments in symbolic logic demand. He divides the history into two parts, the first dealing with what is called the Aristotelian core of logic and the improvements made on that core within a basically classical tradition, and the second, with the tradition of improvements inspired by Leibniz' idea of mathematical logic. The book is brief and much less of a comprehensive history than a prolegomena.--R. (...) H. K. (shrink)

In this book the author develops his own systems of and semantics for presupposition free logic. He calls his systems logics without existence assumptions, by which he means logical systems which are sound and complete with respect to a semantic theory in which a universe of discourse can be empty but any term which denotes must denote something in the universe, all predicates including identity represent relations holding among members of the universe and the quantifiers range over just all the (...) members of the universe. In a brief introductory chapter the author reviews the motivations for constructing non-standard logics of this kind and briefly discusses what he takes to be the limitations of previous work done in the field. Persons interested in the philosophical problems and uses of such logics are likely to find this chapter interesting though disappointingly brief. Four of the eight chapters are devoted to the development of a natural deduction system N which is a logic without existence assumptions in the author's sense. The system N is shown to be sound and complete with respect to the author's semantics. An axiomatic system L is later developed and shown to be equivalent to N. The final chapter is devoted to discussing the relation of his work to many-valued logics, modal logics, intuitionistic logic and the theory of classes among other topics. The author believes that logics without existence assumptions "will in the long run displace the less natural and more narrow standard logics."--R. H. K. (shrink)

This work gives a fresh approach to the discussion of psychological phenomena in philosophical terms. Beginning with a discussion of the emotions and feelings, it works back to a theory of willing and judging. The method is analytic, and the influence of Wittgenstein and Ryle is everywhere in evidence, though in different ways: the author usually improves on what Ryle, but simply approves of what Wittgenstein, says. In the final two chapters, the theory of judgment put forward by Geach in (...) Mental Acts is modified and extended to apply to acts of will, in the light of what has been said in the earlier chapters about emotions, feelings and desires.--R. H. K. (shrink)

Three short essays on the position of the philosopher and philosophy in modern society. Maritain illuminates the situation of the philosopher in a milieu of conflicting systems. The final essay, which deals with the relation of science and religion, shows evidence of a growing appreciation by Maritain of the aims of modern science.--R. H. K.

This collection contains twenty-three papers published by Suppes over the last eighteen years. For the most part they are foundational studies ranging over a wide variety of topics in the philosophy of science. The first two of four parts contain papers on methodological issues like models, measurement, probability and utility. There are two papers on models, an axiomatic treatment of extensive quantity and two papers on measurement. The six papers in Part II deal with probability theory and decision theory with (...) reference to theories of behavior, economics, and other topics. Part III contains studies in the axiomatic foundations of physics, one on relativistic kinematics and three on probability in quantum mechanics. The final and longest section contains eight papers on the foundations of psychology. Several of these deal with the psychological or behavioral bases of mathematics. Others deal with unpredictability in human behavior, finite automata, cognition and other topics. The book is nicely printed and those who have learned from Suppes work in the past will be grateful for this collection of his most important papers.--R. H. K. (shrink)

The translator has collected passages from the varied corpus of Schweitzer's writing and has pieced them together into a brief but impressive sketch of the man and the thinker. Some sections are autobiographical; others contain Schweitzer's thoughts on Africa, world peace, on Goethe and Bach among historical figures, and a few of his basic philosophical ideas. An index provides references to the original works.--R. H. K.

The fact that this study of Russian dialectical materialism originally appeared before the demotion of Stalin should not be allowed to obscure its value as a source book in the development of dialectical materialism in the U.S.S.R. The author notes its limitations in the preface to the second edition and remedies the situation somewhat in a second appendix with an account of significant developments from 1950 to 1958. Each of the two major parts of the main text, the first historical (...) the second systematic, is marked by the author's capacity for terse and pointed analysis of his material.—R. H. K. (shrink)

For a helpful presentation of the various views on probability and inductive logic as well as a thorough survey of the present literature on these topics, one could hardly do better than this work. Kyburg presents, in separate chapters, classical, frequency, logical, subjectivist and epistemological theories of probability, referring to major classical and contemporary works where each of these views is defended. He presents the common criticisms of each view as well as some criticisms of his own and brings out (...) what he takes to be of value in each view. These chapters are preceded by a brief but clear presentation of the probability calculus and a chapter on informal interpretations of probability in ordinary language. A descriptive bibliography follows each chapter in which Kyburg comments on the leading works in each area. The same format applies to his discussion of inductive logic in part II. Inductive inference is discussed in ordinary language and in formal contexts. Statistical inference, confirmation theories, acceptance theories, and demonstrative induction are discussed in separate chapters. There are also discussions of the role of simplicity in inductive inference and the problem of justifying induction. Exercises are added to each chapter and the work might serve well as a text in this field. A forty-eight page bibliography at the end of the book is another one of its assets.--R. H. K. (shrink)

Anyone interested in the highly active field of human communication will find this collection of essays by authors in different disciplines a very useful compendium of present results and problems. Communication theory is related in different essays to current work in Anthropology, Neurophysiology, Organization Theory, Philosophy of Language, Psychiatry, Psycholinguistics, Psychology, Sociology, and several other areas. The editor concludes with an essay "Toward a Theory of Human Communication." Each essay contains a very helpful bibliography of work in the appropriate area (...) and in addition the book contains a general bibliography prepared by Hugh Duncan which includes comments about the contents and nature of each book listed. The excellent essays of Searle and Fodor, Jenkins, and Saporta make the most direct connection with philosophical issues being widely discussed today, but most of the essays provide material which should be of interest to philosophers.--R. H. K. (shrink)

Those looking for extensive accounts of Islamic theological and philosophical systems will not find them in this survey. It presents rather a historical sketch of the political and social forces operating in the Islamic world, from the time of Mohammed to the present, which gave rise to the basic trends in theology and philosophy. The complexity of these forces will impress the Western reader, and those wanting a background for more detailed study of Islamic philosophers and theologians will find the (...) book useful. The first in a series of volumes on Islamic culture directed to the English-speaking student.--R. H. K. (shrink)

As the author states, this book could be read as an introductory text on scientific explanation and related topics or as a monograph which introduces some new ideas and takes a stand on these topics. Part I is strictly a textbook treatment of explanations and laws. It is clearly written and is particularly good in the classification of sorts of explanations. Part II is less successful as introductory material, but it contains some novel ideas. The author develops an approach to (...) explanation, prediction, and retrodiction by considering discrete state systems. He shows that for any number of simple systems of this kind, deterministic and probabilistic explanation, prediction, and retrodiction may not work. The discussion is abstract and the results are not related to actual physical systems. But the possibility of such systems is surely important for any complete theory of explanation as the author suggests. Discussions are also included of teleological systems and of confirming evidence. Part III discusses philosophical issues about the nature of laws, causality, indeterminism, and the limits of explanation. Two appendices discuss problems of scientific explanation in history and the social sciences. There is a long and very useful bibliography.--R. H. K. (shrink)

In this very brief space the author summarizes in the form of a succession of theses, all but the purely historical sections of Osnovy Marksistskoj Filosofii, the 1958 text of Soviet Marxist Philosophy published by the Institute of Philosophy and the Academy of Sciences of the Soviet Union. For specialists, this synopsis cannot replace the original text, as yet untranslated into English, but it will provide for the general reader an excellent summary of what is currently, in the author's words, (...) "the heart of Soviet dogma." Philosophically significant theses are given in direct translation. The only complaint would be that the price of this slim volume is rather high.—R. H. K. (shrink)

The debate between hard and soft determinists is dealt with in this brief but interesting study. The author argues that there is no empirical dispute between hard and soft determinists. They draw different conclusions from the observed facts and these differences are the result of using different senses of the terms 'freedom' and 'moral responsibility'. Moritz Schlick's Problems of Ethics is the author's favored source for the soft determinist position and well-known articles by Paul Edwards and John Hospers the sources (...) for hard determinism. Other writers are quoted and briefly discussed. The treatment of many criticisms and countercriticisms is all too brief to do full justice to all the issues involved, but those topics which the author discusses are often illuminated. Interesting things are said about such topics as kleptomania, post-hypnotic suggestion, punishment, and excusable behavior. The book makes a convincing case, at least for the claim that a sophisticated version of the hard determinist position, such as appears in Hospers article, is only verbally different than many versions of soft determinism. Other versions of hard and soft determinism can and do come in substantive conflict with one another.--R. H. K. (shrink)

The essays collected in this volume to honor Ernest Nagel reflect his wide interest in all topics relating philosophy to the natural and social sciences. The essays, written by distinguished philosophers and scientists form a mixed bag, but most of them are very good. The first part, "Science and Inquiry" begins with notes taken by Patrick Suppes of Nagel's lectures on Dewey's logic delivered in 1947. It follows with essays on knowledge by Stuart Hampshire, on intensions and the law of (...) inverse variation by R. M. Martin, and four essays on problems of induction and confirmation which contribute markedly to this well-worn field. The eleven essays of the second part, "Structure of Science" range from discussions of physics and ontology, mechanism and evolution to essays on functionalism in anthropology and ethics and legal theory. In between there are very good essays by C. Hempel on reduction, S. Morgenbesser on the realist-instrumentalist controversy, essays on the identity thesis, extensive measurement, causation and action, philosophy of language, and the differences between the natural and social sciences. Part three contains six essays on the role of values in various settings, e.g., ethical theory, the social sciences, legal theory and existentialism. The fourth and final part contains a variety of historical studies: Clagett on the quadrature of lunes in medieval science, I. Bernard Cohen on Newton, A. Koslow on the law of inertia, Charles Parsons on Kant's philosophy of arithmetic, Philip Wiener on a Soviet view of Peirce's pragmatism and S. Diamond on John D. Rockefeller and the historians.--R.

The much neglected "fifth sense" provides the subject matter for this analytical study. The author distinguishes two kinds of perception associated with this sense, perception by touch and perception of bodily state, and gives an account of the nature of the sensations proper to each. The latter are divided into intransitive bodily sensations and transitive bodily sensations. The greater part of the book is devoted to developing the thesis that bodily sensations can be interpreted as sense impressions of occurrences in (...) our own body.--R. H. K. (shrink)

This fifth volume in the Boston Studies in the Philosophy of Science is devoted primarily to the natural sciences, but like previous volumes in this series there is considerable variety in the topics discussed and the approaches taken by different contributors differ markedly. The first contribution is a 150 page essay by A. Grünbaum which is a reply to Hilary Putnam's critique of Grünbaum's philosophy of geometry. The essays by Peter Havas on causality and relativity and by Carl F. von (...) Weizäcker on the unity of physics are essays on the foundations of physical science by physicists who have distinguished themselves in this area. Helpful comments are added to the Havas' paper by John Stachel and to the von Weizäcker paper by Francis Zucker. Zucker provides a useful introduction to von Weizäcker's ambitious project of unifying physics for reader's unfamiliar with von Weizäcker's work. A symposium on theoretical entities and functional explanation in biology is included, with a paper by June Goodfield and comments by Ernst Mayr and Joseph Agassi. Historical essays include a discussion of hypotheses in Newton's philosophy and the development of the cognitive faculties in the theories of Ernst Mach. In addition, there are essays on logic in relation to physical science, measurement, models, symmetry, proof, truth, and the Copenhagen interpretation of quantum theory.--R. H. K. (shrink)

The German philosopher Rickert substituted for Hegel's formulation of the dialectic a "Heterological Principle of Thought" where identity and otherness become moments within the pure logical object of thought. The logical object of thought takes precedence over dialectical movement, and otherness takes precedence over negation. Flach expounds and defends Rickert's position against its critics. The discussion is specialized but contains some valuable insights into Hegel. --R. H. K.

A physicist searches for models with which to interpret the idea of atomicity in modern physical theory. He favors a notion of atomic connexions over traditional particle and wave interpretations. The implications of physical theory, it is argued, cannot be understood without a familiarity with the mathematical tools, and in particular the experimental procedures of physicists. This is not a crude operationalism but a simple statement of the thesis that much writing in the philosophy of science is of less value (...) than it could be were more attention given to matters of experimental practice.--R. H. K. (shrink)

This is a collection of essays written by Hintikka over a period of eight or nine years on logics of existence and on the semantics of modal logics, areas in which he has made pioneer studies. The introductory essay defends formal methods in philosophical analysis. Two essays follow on logics of existence, one of them relating such logics to discussions of the ontological argument. Of the four essays on the semantics of modal logics, the first two "Modality and Quantification" and (...) "The Modes of Modality" discuss the possibilities for philosophical work with the semantics of modal logics generally and the second two "Semantics for Propositional Attitudes" and "Existential Presuppositions and Uniqueness Presuppositions" discuss philosophical applications and try to deal with some of Quine's objections to modal logics. Two final essays apply Hintikka's methods to problems in the philosophy of perception and metaethics. In a paper "On the Logic of Perception" he discusses the nature of immediate perception and sense-data theories and in a paper "Deontic Logic and its Philosophical Morals" he discusses the distinction between prima facie and absolute obligation and John Searle's attempted derivation of "ought" from "is." All essays but this last one have been previously published, but not all in places readily available to English-speaking readers.--R. H. K. (shrink)

Foundations research in physics, according to Bunge, has lagged behind its sister discipline, the foundations of mathematics. His book is an attempt to partially remedy this situation by analyzing the form and content of some basic ideas in physics and presenting some of the fundamental theories of physics in an axiomatic fashion. The heart of the book consists of axiomatizations of Classical Mechanics, Classical Field Theories, and Quantum Mechanics. Bunge does not claim to be working without predecessors. While the idea (...) of a separate discipline in the foundations of physics is rather new, the existence of material that clearly belongs to foundations research is not. This is attested to by the substantial bibliography at the end of the book. But he is ideally suited to the task of bringing this difficult material together and welding it in his own fashion into a coherent whole. His grasp of physical theory is wide-ranging and he writes with clarity and wit. In the first chapter he states his views on a number of issues in the philosophy of science: explanation, prediction, operationalism, laws, and other topics. The arguments are usually summarized very briefly, or reference is made to other books. Thus those who disagree with his philosophical presuppositions will not be convinced; but friends or foes will miss a great deal of informative material if they do not push on to the axiomatizations which follow and which are the main concern of the book. This book will undoubtedly be a source-book for future foundations research in the physical sciences.--R. H. K. (shrink)

This book is a study of meaning and meaninglessness which takes as its point of departure a discussion of sentences like "The theory of relativity is blue" which some philosophers call category mistakes and which this author calls type crossings. His answer to the question of the basis of the meaninglessness of such sentences differs from most currently fashionable ones. For example, he argues in separate chapters against the view that the basis for the meaninglessness of sentences involving type crossings (...) is in the fact that they are ungrammatical. He also rejects the view that this basis is in the fact that the sentences violate certain rules of language His answer is that type crossings are meaningless because they designate unthinkable propositions. He then devotes two long and crucial chapters to an attempt to elaborate on the notion of unthinkability. His approach is more complicated than this brief summary would suggest for he distinguishes between accidental and essential properties and relations, requiring different criteria for type crossings involving accidental or essential attributes. Drange's views run against the grain of much contemporary philosophizing about meaning, e.g., his essentialism, his advocacy of a kind of synthetic a priori and his emphasis on thinkability over rules of language. But he comes to these positions by exposing what he takes to be difficulties in alternative views, so that his views are always challenging. Aside from its main theses, the book looks into topics about meaning and type crossings which other writers have scarcely noticed or discussed. For example, he tries to come to grips with the largely uncharted region of type crossings involving relational properties and those involving types other than types of things.--R. H. K. (shrink)

In spite of the title, the author of this book asserts that its primary aim is to offer a reasonable account of the concepts of possibility and potentiality. His analysis of these concepts allows him to approach the free will controversy in his own way and to offer many interesting analyses and arguments bearing on the issue. He distinguishes three kinds of non-logical possibility: epistemic or relative possibility, natural possibility or natural power, and possibility of choice or personal power. He (...) thinks that the arguments for determinism have been based in one way or another on a failure to notice the subtle differences which exist between these three kinds of non-logical possibility. Although there is room for doubt that his analysis adds up to a decisive refutation of determinism, he has found many interesting differences between kinds of possibility and potentiality which bear on the free will issue and other philosophical issues as well. There is a discernible influence of Ryle and Austin on the book although both of these philosophers come in for criticism, especially Ryle for his failure to carefully separate the different meanings of 'power', 'tendency', 'capacity', and similar terms, and for his general commitment to the notion that all power is conditional. This latter thesis is one of the author's main targets.--R. H. K. (shrink)

In this work R. M. Martin carries his semiotical studies into the fields of intensional semantics and pragmatics, dealing with such philosophically important concepts as meaning, preference, reasonableness and indifference. The crucial notion is that of the meaning or intension of an expression. Two major categories are distinguished, objective intensions and subjective intensions. To deal with objective intensions an intensional semantics is developed as an extension of denotational semantics in the tradition of Tarski, Carnap and Martin's earlier Truth and Denotation. (...) In the treatment of subjective intensions Martin makes an advance over his earlier study of pragmatics by utilizing the work of von Neumann and Morgenstern in their Theory of Games and Economic Behavior.—R.

This book is an introduction to certain problems in the philosophy of science through the study of four case histories in the history of science. It is designed for undergraduate science majors whom, the author feels, often have difficulties connecting the usual discussions in the philosophy of science with the science they have studied and are studying. Each case history is followed by a commentary which considers its philosophical implications. The first case, Harvey's discovery of the circulation of the blood, (...) is treated briefly and from it some implications are drawn about the relation of simple theories and the facts supporting them. The next three cases are considerably more complicated and receive more extended treatment. The first of these concerns scientific work on the motions and spacing of the planets from early Babylonian and Greek observations and theories to Kepler and Newton. The second concerns the development of the periodic table of the elements from Dalton to Mendeleev and the third discusses gene theories of inheritance from Mendel onward. In connection with these studies the author considers questions about the nature of theories and theoretical entities, methods of testing theories, the dependence of observation on theory and the issues of reduction among other topics. Although he limits his discussion to a few selected topics in the philosophy of science he has written an informative and interesting study which should fulfill its stated aims.--R. H. K. (shrink)

This is the first of a number of volumes designed to review the philosophical work which has been done in various areas of philosophy between the years 1956 and 1966. It succeeds an earlier three volume publication entitled Philosophy in the Mid-Century which covered the period from 1949 to 1955. This first volume in the series covers the fields of logic, philosophical logic, foundations and philosophy of mathematics. For anyone interested in these fields, the book is an indispensable guide. The (...) procedure is that an expert in a given area writes a summary of the work done in the area in the last ten years and adds a bibliography covering the same period. In all there are thirty-two such essays, most written in English, but a few in French and German. Some representative essays and their authors are the following: On the logical side, Modal Logic, Many Valued Logics, Logic of Practical Discourse, Semantics, Model Theory, Pragmatics, Chronological or Tense Logic, The Logic of Questions, Combinatory Logic and others. There are two general essays on recent developments in philosophical logic and a number of essays on the development of logic in various Eastern and Western European countries and Japan. On the mathematical side are three essays on foundations of set theory and mathematics, essays on Intuitionism in mathematics, and general essays by A. Church, H. Freudenthal and others. The essays are generally of high caliber and the bibliographies in most cases very comprehensive. Occasionally the essays contain not only summary of work done but original suggestions and development of ideas. It would be hard to find a more useful guide for the philosopher overwhelmed by the many developments in these fields in recent years.--R. H. K. (shrink)

This second volume in the series designed to review the work done in various areas of philosophy during the period 1956-1966 is concerned with the philosophy of science. There are forty essays on a variety of topics in the philosophy of science describing the work done in that area in the past decade and a bibliography covering the same period. Most are in English, some in French or German. Some representative topics and their authors are: Laws, Models, Causality, Induction and (...) Probability, Scientific Methodology, Time, Space, Cosmology, Philosophy and Physics, Quantum Theory, Biology and Philosophy. In addition there are several general essays on the influence of various philosophers and scientists on current developments in the philosophy of science, on the ethical and philosophical implications of science, on Cybernetics, Information Theory, Game theory and a number of essays on the development of philosophy of science in different countries of Western and Eastern Europe and Japan. Like the first volume of this series, this book is an indispensable guide to anyone interested in the field, and a place should be made for it on every library shelf---where there is an interest in philosophy of science.--R.

This publication of the proceedings of the first of a new series of colloquia to be held at the University of Western Ontario contains an opening address on existence and quantification by W. V. Quine and three symposia. The paper discussed in the first of these symposia, "Descartes' Ontological Argument" by Anthony Kenny, follows closely one chapter of Kenny's recent book on Descartes. Kenny's paper contains both an interesting account of Descartes' views and some challenging remarks about ontological arguments in (...) general. His paper is discussed in separate commentaries by Norman Malcolm and Terence Penelhum. An interesting feature of this volume is that some comments from the floor are recorded and included along with the regular commentaries. Ernest Sosa and Bernard Williams comment on Kenny's paper along with Malcolm and Penelhum. Kenny responds to all four commentators. The other two symposia follow a similar format. The second, "On Events and Event-descriptions," features a paper by R. M. Martin which focuses on the logic of event descriptions and their role in scientific explanation. Events for Martin are extensional entities, unlike facts, but like facts they are "fictitious in the sense of being handled on virtually." His views are discussed by Donald Davidson, R. J. Butler and Wesley Salmon. In the third symposium on "Existence Assumptions in Practical Thinking," Stephan Körner elaborates on his view of effective choice, relating his account to those of Hume, Kant, and Peirce on the specific topic of the relationship of choice and natural necessity. The commentaries of J. J. Thomson and Bernard Williams are helpful here in getting Körner to clarify his interesting views. In sum, this first colloquium at the University of Western Ontario features genuine philosophical communication on some important issues.--R. H. K. (shrink)
