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)

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)

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.

The first part of this long two-part work is a history of the development of the modern theory of the atom from Dalton to the present. The second part offers philosophical reflections on this history beginning with a discussion of epistemological implications and following that with an account of ontological implications. The author deals with familiar questions about the reality of micro-particles, complementarity, indeterminism, the role of the observer and other topics. But he also discusses topics like holism, atomic order, (...) the intelligibility of matter and others which are less commonly discussed by philosophers in connection with modern physical theories. The author, who is trained in physics as well as philosophy, has a flair for metaphysical speculation as well as wide knowledge of contemporary physical theory. He stresses the novelties of the quantum conception of matter, argues against its critics like Bohm, and sees it as presenting a radically new conception of atomic order despite its commitment to indeterminism. The views of Werner Heisenberg, who encouraged the author to write the book and who read it in manuscript, have clearly influenced the author, although they do not dominate his thinking.--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 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)

One of the aims of this book is to bring contemporary research in the neurological and physiological sciences into relationship with discussions in the philosophy of mind. The author does not deny the significance of ordinary talk about the mind, including talk about actions, intentions, beliefs and the like, but he wants to see how this language is compatible with evolutionary and neurophysiological accounts of man. He frequently refers to and accepts Charles Taylor's arguments that "peripheralist" or S-R behavioral theories (...) fail to account for the intentionality of mental states and the teleology of behavior. In fact, one way of reading this book is to see it as an attempt to answer a question raised by Taylor's book: If "peripheralist" theories of behavior cannot account for intentionality and teleology, can a "centralist" or neurophysiological theory of man account for these characteristics? The key chapters of the book attempt to answer this question in the affirmative. The author thinks of the intentionalist characterization of the physical structures of behavior as a "heuristic overlay" on the extensional account of functioning. But the two descriptions, intentional and extensional, are linked together by a series of hypotheses describing the evolutionary source of the functioning. The important problem is to explain how conceptual content or information gets into the neurophysiological picture. The author attempts to deal with this as well as with other problems about the nature of mind including introspection, consciousness, imagery, reasoning, intention, action and language. His discussion of the neurophysiological background for his speculations is purposely general in order to free his conclusions from specific empirical hypotheses about the nervous system which may turn out to be false. This purposeful limitation makes his argument less convincing in some places than it might have been. But he is asking important questions and offering answers to them which deserve careful consideration.--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)

The chief topics discussed in this carefully written book are the nature of definitions in science, the distinction between observational and theoretical terms, changes in scientific concepts and the role of analogies and models in science. The unifying theme is that of meaning in the sciences. Its treatment by Achinstein indicates a trend in recent philosophy of science toward finding a middle ground between two antithetical positions on the topic of the meaning of scientific terms. On the one side stands (...) the traditional positivist and logical empiricist account which distinguishes sharply between the meaning of observational and theoretical terms, and on the other side, the more recent views of Feyerabend, Kuhn, Hanson, Toulmin and others who stress the dependence of the meaning of observational terms on that of theoretical terms and the change of meaning of all terms connected with a theory when the theory changes. Achinstein argues cogently that the extreme versions of these positions will not work. Their main problem is that their treatment of meaning is too rigid and monolithic. His own discussion of meaning in the early chapters on definition bristles with distinctions, nuances, and concrete examples from the sciences. In terms of the distinctions of this part of the book he is later able to argue against Feyerabend and Kuhn that in changes of scientific concepts such as characterize scientific revolutions not all of the meaning connections of the various terms need be altered. He also argues that of the many ways proposed to distinguish between theoretical and observational terms, no one is fundamental, though each may be relevant to certain categories of questions one might want to raise about scientific terms. This book thus leads away from the simpler doctrinal statements of the past about the meaning of scientific terms toward a theory of meaning requiring more distinctions, qualifications, nuances, and more subtlety all around.--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. 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)

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)

In this phenomenological approach to meaning, the author defines his task as one of taking account of the kinds of relations the logical order can have to the preconceptual order. This preconceptual order is represented by a pre-logical activity which is called "experiencing." There is experiencing of meaning as well as of things. This "experienced or felt meaning" is said to be as important a dimension of meaning as the traditional modes distinguished by philosophers, e.g., denotation, connotation. Apparent throughout is (...) the author's concern as a psychotherapist to find theoretical foundations for clinical methods.--R. H. K. (shrink)

This is the first comprehensive study of Schrödinger's scientific and philosophical writings. The task requires a person trained thoroughly in physical science and yet capable of appreciating the sometimes puzzling philosophical ideas Schrödinger put forward. Professor Scott, a physicist, is remarkably successful at communicating both the physical and the philosophical ideas. After a brief summary of Schrödinger's diverse writings, he divides the writings into four groups which are treated in separate chapters. The first group, including very early papers, deals with (...) Schrödinger's work on Statistical Mechanics, and statistical theories in general. The second covers the crucial development of Wave Mechanics. The third concerns Schrödinger's interpretation of quantum mechanics and the important departures from the prevailing views of the Copenhagen school. Finally the fourth group contains Schrödinger's views on life and the self. The author shows that Schrödinger was led to his doctrine of identity by reflecting on the paradox of freedom and determinism. His study "What is Life?" convinced him that living systems are governed by the law of causality but he also believed that men were free. The doctrine of identity was his solution to the paradox. Scott is critical of this solution and a number of other doctrines of Schrödinger. The book is clearly written throughout and is a good introduction to Schrödinger's thought.--R. H. K. (shrink)

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)

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 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)

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)

As Max Jammer has rightly said, contemporary discussion of the metrical properties of space have been dominated in recent years by the work of Adolf Grünbaum. One of Grünbaum's most important essays in this area, "Geometry, Chronometry and Empiricism" is reprinted in its entirety as the first chapter of this work. The third and final chapter is a lengthy reply to Hilary Putnam who published a critique of Grünbaum's original essay in 1963. Putnam's criticisms have not led Grünbaum to substantially (...) change his views but they have provided the means for some clarification and extension of those views, e.g., with respect to the notions of congruence and conventionality and in relation to Zeno's paradoxes, color attributes, and other topics. Between the original essay and the lengthy reply to Putnam there is a shorter chapter which deals with, among other things, the hypothesis that everything has doubled overnight, a related topic to which Grünbaum has given some attention in journal articles. It is safe to say that persons concerned with the problem of conventionalism and other philosophical problems about space will have to work their way through this important book.--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)

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)

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)

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)

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 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.

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)

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)

Suzanne Langer's earlier works on the philosophy of art, particularly her Feeling and Form, are the points of departure for this general study of the phenomena of life and mind which she clearly intends to be her magnum opus. This is the first of two volumes, the second volume as yet unpublished. Her main thesis is that the "departure [of man] from the normal pattern of animal mentality is a vast and special evolution of feeling in the hominoid stock". She (...) opposes all attempts to bifurcate nature into matter and mind, and in this regard aligns herself with the main currents of contemporary thought. But the centrality she gives to the notion of feeling is uniquely her own, separating her views from those of most other contemporary thinkers and providing the most controversial part of her book. In different places throughout the work, the term "feeling" includes within its scope "sensation," "inward tension," "pain," "emotion," "intent," and a number of other phenomena. Critics of the work will no doubt argue that the theory cannot overcome the vagueness engendered by giving this central concept such a wide scope. But before making a final judgment on this point they will have to pay special attention to the second and third parts of this book where her concept of feeling slowly takes shape through reflection on the arts and on the nature of living things. In a second volume she promises to move beyond living things in general to the distinctive features of human consciousness. A second respect in which this work differs from much other writing in the philosophy of mind is the wealth of references and examples from the biological and psychological sciences which display the encyclopedic interests and openness which have always characterized Suzanne Langer's writings.--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."

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)

A critical treatment of four basic methodological principles of science: simplicity, micro-reduction, verification, and connectivity. In each case, the major question is whether, and on what grounds, the principle can be justified. This quest for justification should be of particular interest to those concerned with the philosophy of science from the standpoint of epistemology and metaphysics.--R. H. K.

This third volume of the Minnesota series differs from the first two in its greater emphasis on the methodology of the physical sciences. Most of the interest of these earlier volumes was directed to an analysis of the concepts of psychology, psycho-analysis, and the philosophy of mind. The concept of scientific explanation is here analyzed in successive papers by Feyerabend, Hempel, Scriven, and Brodbeck; and the problem of the status of theoretical entities in science is treated by Maxwell and Rozeboom. (...) The volume closes with two lengthy articles on problems surrounding the concepts of space and time. The first, by A. Grünbaum, makes a thorough attempt to resolve the problem of conventionalism in physical science; and the other, a detailed analysis by W. Sellars, examines the concepts of existence, becoming, event, and truth in their relationships to the concept of time. This important addition to the Minnesota series confirms the impression of the earlier volumes, that, although the contributors differ in details, they share the common goal of formulating, with the tools of modern logical and linguistic analysis, a reasonable empiricist interpretation of modern science which will avoid the dogmas and crudities of the empiricisms as well as the rationalisms of the past.--R.

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.

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.

Suzanne Langer's earlier works on the philosophy of art, particularly her Feeling and Form, are the points of departure for this general study of the phenomena of life and mind which she clearly intends to be her magnum opus. This is the first of two volumes, the second volume as yet unpublished. Her main thesis is that the "departure [of man] from the normal pattern of animal mentality is a vast and special evolution of feeling in the hominoid stock". She (...) opposes all attempts to bifurcate nature into matter and mind, and in this regard aligns herself with the main currents of contemporary thought. But the centrality she gives to the notion of feeling is uniquely her own, separating her views from those of most other contemporary thinkers and providing the most controversial part of her book. In different places throughout the work, the term "feeling" includes within its scope "sensation," "inward tension," "pain," "emotion," "intent," and a number of other phenomena. Critics of the work will no doubt argue that the theory cannot overcome the vagueness engendered by giving this central concept such a wide scope. But before making a final judgment on this point they will have to pay special attention to the second and third parts of this book where her concept of feeling slowly takes shape through reflection on the arts and on the nature of living things. In a second volume she promises to move beyond living things in general to the distinctive features of human consciousness. A second respect in which this work differs from much other writing in the philosophy of mind is the wealth of references and examples from the biological and psychological sciences which display the encyclopedic interests and openness which have always characterized Suzanne Langer's writings.--R. H. K. (shrink)

The author attempts to extract from Carnap’s writings a coherent theory of the nature of philosophical questions and then tries to defend this theory against criticism from various quarters. Special attention is given in the middle chapters to the alternative views of Quine on ontological questions and ontological commitment and to Quine’s criticisms of related Carnapian views.

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.

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)

In the introduction to this bibliography of works in the philosophy of science, the author stresses that it provides only the éléments of a bibliography and does not claim to be complete. His aim is to provide a starting point around which interested parties can build their own bibliographies. Although it may be of some use in this regard, philosophers of science in the English-speaking world will not find the volume of very much use for authors writing in English. Some (...) authors are not listed at all and others who do appear have only two or three listings. Examples could be multiplied, but these provide a representative picture of the volume's limitations in this regard. On the other hand, as a preliminary guide to books and articles in the philosophy of science by authors writing in different languages than one's own, the book can be of undoubted usefulness. Works in most of the languages of Western Europe are listed, the majority in French, German and Italian, as well as English.--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.

This anthology collects readings from important nineteenth and early twentieth century figures who contributed to the philosophy of science before that discipline emerged in the last 40 years as an area of study in its own right. It begins with a seldom-read selection by Kant ) and ends with a selection from Bridgman's The Logic of Modern Physics. Each selection is preceded by a three-page biography of the author together with a bibliography of his major writings and some writings on (...) his work. Many familiar names appear, e.g., Mill, Mach, Pearson, Hertz, Poincare, Peirce, Duhem, Russell, Whitehead, and Campbell. But there are others represented whose actual writings are not so familiar to many students of the philosophy of science, e.g., J. F. W. Herschel, William Whewell, Hermann Von Helmholtz, J. B. Stallo, Emile Boutroux and William Ostwald. With the exception of Stallo, the writings of these figures have been long out of print. In one case, a selection from Ludwig Boltzmann on the nature of mechanics, the editor has translated the selected passage into English expressly for this volume. A wide range of topics are considered in the readings: physical laws, theories, induction, observation, space, time, and others; but, as the nature of the case requires, the focus of attention is on classical science. For this reason most existing courses in the philosophy of science could use this collection only as a supplementary text. But it would function well in such a role. Moreover, specialized courses in the history of philosophical thinking about science will find it very useful.--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 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.

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.

The problem of perception is one of specifying correct and consistent meanings for the concepts we use in talking about it. The most frequent mistake in the history of this concept has been to "reduce" perception either to sensation or to judgment. With this in mind, the author deals primarily with the period from Descartes to Kant, though ancient, medieval, and contemporary developments are also treated.--R. H. K.

Two fundamental theses of sensationalism as a theory of science, formulated by Mach and influential since his time, are critically treated in this analytic study. The first is that the basic elements of experience are sensations, the second that scientific explanation is no more than a complete description of phenomena in terms of sensations. In arguing against these claims the author touches on many important issues in the philosophy of science, including questions about the nature of description and explanation. He (...) argues against the view that there are no pure descriptions, in the sense of descriptions which are free of interpretation.--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.
