This volume offers a collection of in-depth explorations of pragmatism as a framework for discussions in philosophy of science and metaphysics. Each chapter involves explicit reflection on what it means to be pragmatist, and how to use pragmatism as a guiding framework in addressing topics such as realism, unification, fundamentality, truth, laws, reduction, and more. -/- .

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 This is the first of two volumes, the second volume as yet unpublished.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.

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

The 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.

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)

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)

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)

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.

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)

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)

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)

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

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)

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

In 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)

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)

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.

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)

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

The 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)

The essays in philosophical logic collected in this volume are dedicated to Henry S. Leonard who was one of the first American philosophers to urge the application of modern logic to non-mathematical areas. Leonard also inspired the development of certain areas of contemporary philosophical logic discussed in some of the papers of this volume. This is especially clear in the case of free, or presupposition free, logics which Leonard's early work on a logic of existence inspired. In one essay of (...) this volume Bas C. Van Frassen further develops his work on the semantics of free logic. In another, Milton Fisk relates free logic to modal logic, suggesting a new semantics of strength to deal with various problems in the area and in a third essay, Karel Lambert relates free logic to certain logical puzzles about quantum theory. Leonard was also one of the first to entertain the idea of and discuss a logic of questions and an erotetic logic or logic of interests. The volume contains essays on these topics by Nuel D. Belnap and David Harrah. Leonard's interest in modal logic is reflected in Fisk's article as well as in an article by Richmond Thomason on modal logic and metaphysics. His interest in epistemic logic is seen in an essay on the logic of belief by Jon Vickers and an essay by Hintikka applying the logic of belief and knowledge to problems about the ontological argument. In addition to these essays, there are five others of high quality on diverse topics: R. M. Martin on intentions, Wilfrid Sellars on the metaphysics of the person, R. M. Chisholm on agency, Frederick Fitch on combinatory logic and negative numbers, and H. E. Hendry and G. J. Massey on Sheffer functions. This is a worthy memorial to a quietly influential American philosopher.--R. H. K. (shrink)

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