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. -/- .

Originally published as a long essay in Mind and Cosmos, Volume II of the University of Pittsburgh series in the philosophy of science, this study admirably fills the need for an elementary survey of problems in the area of probability and induction. But it is more than an introduction. The author is working on the general thesis that Bayes' theorem of the probability calculus holds the key to the understanding of scientific inference. Guided by this idea he attempts to salvage (...) what he thinks is of value in various current theories of probability and scientific inference, particularly, the frequency theory of probability as defended by Reichenbach, Popper's views on the falsifiability of theories, and Hanson's work on the logic of discovery. These attempts to develop a theory in the latter part of the book follow discussions of Hume's critique of induction, the probability calculus and five past and present interpretations of the calculus. This is a well-written and challenging introduction to the field.—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)

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)

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)

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 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.

Rapid handwriting, popularly known as shorthand, involves writing symbols and abbreviations in lieu of common words or phrases. This method increases the speed of transcription and is primarily used to record oral dictation. Someone skilled in shorthand will be able to write as fast as the dictation occurs, and these patterns are later transliterated into actual, natural language words. A new kind of rapid handwriting scheme is proposed, called the Pattern-Based Shorthand. A word on a keyboard involves pressing a unique (...) sequence of keys in a particular order. This sequence forms a pattern that defines the word. Such a pattern forms the shorthand for that word. Speech recognition involves identifying, by a machine, the words spoken by a speaker. These spoken words form speech input signals to a computer that is equipped to correctly recognize the words and do further action, such as convert it to text. From this text input, unique shorthand patterns are generated by the system. The system employs machine learning to improve its performance with experience, by creating a dictionary of mappings from word to patterns in such a way that the access to existing patterns is faster with progression. This forms a new knowledge representation schema that reduces the redundancy in the storage of words and the length of information content. In conclusion, the speech is converted into textual form and then reconstructed into Pattern-Based Shorthand. (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.

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. 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)

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 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)

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)

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.

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

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.

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)

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)

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)
