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)
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.

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)
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)
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.
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)
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)
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)
This volume claims to offer first a correct interpretation of Hume's theory of causation, and second, a philosophical defense of it against many recent criticisms. The first two chapters try to reconcile Hume's two definitions of "cause," and to prove that Hume was not a skeptic about induction. The authors contend that Hume's views on causation can be rationally reconstructed as a unified theory that is, they believe, faithful to his intentions, namely that causation involves regularities or constant conjunctions, and (...) some kind of necessity.

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)
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)
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.
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 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.
The author tries to show that modern western science is coherent with past philosophical speculation, both western and eastern. Some of the book's 9 chapters have previously been published in American and Indian journals.--R. H.
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.

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)
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)
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)
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)
Science in a Free Society is the sequel to Feyerabend's earlier iconoclastic, provocative book, Against Method. As he states in the preface: "Like the earlier book this volume has one aim: to remove obstacles intellectuals and specialists create for traditions different from their own and to prepare the removal of the specialists themselves from the life centers of society". The book is divided into three parts: Part 1 resumes the argument presented in Against Method; part 2 extends the implications of (...) that position to the conception of a "free society"; and part 3 contains a revealing autobiographical account along with answers to his critics--no less inhibited in style than his earlier book. Thus the conclusions in this volume should be viewed as an extension of the arguments of the previous essay. (shrink)
A careful presentation of the foundations of probability theory, containing many valuable innovations. Two accounts of probability are adduced: probability as a measure on the subsets of a probability set, and as a measure on the sentences of a formal language. The book stresses connections between these two accounts; of particular interest is its thesis that statistical probabilities may be regarded as estimates of inductive probabilities.—R. H. T.
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)
Fr. Butler centers attention on Santayana's doctrine of essence, seen as the expression of a total outlook on life, as well as of a theory of knowledge. The basic criticism is that Santayana's scepticism and "essentialism" arise from a self-defeating doubt about the existence of knowledge.--R. H.
An interesting book, offering a forceful criticism of some classical and modern traditions in philosophy, especially of speculative idealism, phenomenology, and existentialism. The argument is not so much an attack on the explicit theories of these traditions as it is a criticism of their underlying assumptions about the purpose and limits of philosophizing itself. For the author this purpose has been and must always be the clarification of "confusions," as against the discovery of ultimate truths about reality.--R. H.
An independent attempt to discover the standards of judging goodness and right, based on a description of the ways in which such judgments arise in economics and law. The approach and outcome are generally Kantian, and the author concludes with an effort to reconcile the claims of causality and freedom.--R. H.
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 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)
Shows the Enlightenment concern with human affairs, and in particular with the problem of human knowledge, by extensive selections from Locke's Essay, and the Treatises of Berkeley and Hume. The editor's comments point out major confusions and errors, and aid the reader in understanding the selections in their own terms.--R. H.
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.
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)
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)
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)
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)
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. H. K. (shrink)
A development of a constructive fragment of analysis: "constructive" in the strong sense that instead of, say, Cauchy sequences, it deals only with recursive sequences of rationals which can be recursively shown to converge. Analogues of classical subjects such as continuity and differentiability are explored in detail. The book presupposes familiarity with both classical analysis and the theory of recursive functions.—R. H. T.
