Many structures in nature are invariant under the transformation pair, (p,r)→(b r,−p/b), where b is some scale factor. Born’s reciprocity hypothesis affirms that this invariance extends to the entire Hamiltonian and equations of motion. We investigate this idea for atomic physics and galactic motion, where one is basically dealing with a 1/r potential and the observations are very accurate, so as to determine the scale b≡mΩ. We find that an Ω∼1.5×10−15 s−1 has essentially no effect on atomic physics but might (...) possibly offer an explanation for galactic rotation, without invoking dark matter. (shrink)

This article proposes a new global approach to the history of science centered on questions of geopolitics, historical consciousness, and cultural identity. Arguing that the field is now at a crossroads between its longstanding focus on the history of the natural sciences in the Western world, and the prospect of some form of worldwide history of science, the article describes a new undergraduate lecture course, designed by the author and taught at Rutgers and Harvard since 2015, which neither begins in (...) Western Europe nor culminates with the United States. It aims to articulate an original vision for the field on this basis. Histories of science can and should offer deep histories of the global present, it is argued, by rethinking how historical narratives involve geographical decisions about where to focus analytical attention (and where not) and tackling narrative and geography together as linked issues. The approach proposed here is neither science in context nor knowledge in transit but engages the notion of a knowing world: one made up of multiple scientific cultures and long historical memory, and requiring dialectical movement back and forth across both space and time on a worldwide scale to grasp the scientific past’s importance for the present, as well as the present’s impact on how we perceive the past. Explicitly addressing polemics of identity, culture, race, and nationhood can help us to construct a more civic-minded and geopolitically informed history of science of use in the changing circumstances of the twenty-first century.

Anthropologists, linguists, cultural historians, and literary scholars have long emphasized the value of examining writing as a material practice and have often invoked the list as a paradigmatic example thereof. This Focus section explores how lists can open up fresh possibilities for research in the history of science. Drawing on examples from the early modern period, the contributors argue that attention to practices of list making reveals important relations between mercantile, administrative, and scientific attempts to organize the contents of the (...) world. Early modern lists projected both spatial and temporal visions of nature: they inventoried objects in the process of exchange and collection; they projected possible trajectories for future endeavor; they publicized the social identities of scientific practitioners; and they became research tools that transformed understandings of the natural order.

Historians and commentators have long discussed tensions between specialist and lay expertise in the making of scientific knowledge. Such accounts have often described quarrels over the distribution of expertise in nineteenth-century “popular” and imperial sciences. The “crowdsourcing” of science on a global scale, however, arguably began in the early modern era. This essay examines the lists of specimen suppliers, the artifacts of a worldwide collecting campaign, published by the London apothecary James Petiver at the turn of the eighteenth century. Listing (...) suppliers helped Petiver advertise his status as a global specimen broker in the Republic of Letters. However, publicly listing his sources drew criticism over the social character of his collecting project, while lists became synonymous with the debasement of learning in polemics over natural history.

That objects of knowledge get moved across boundaries is well known. But how they get moved often goes unexamined. Modes of movement cannot be ignored when considering objects’ historical signi?cance. Put differently, how geographies are negotiated is central to the constitution of knowledge objects. This essay offers a brief assessment of the competing agencies at work in the global collections of the Enlightenment naturalist Sir Hans Sloane (1660–1753). While discussing broadly the relationship between collecting and power in Sloane’s career, the (...) essay stresses the passivity and strategic weakness of the collector, and suggests how the meanings of speci?c curiosities varied according to asymmetries in their mode of transfer.

We discuss five kinds of representations of rationales and provide a formal account of how they can alter disputation. The formal model of disputation is derived from recent work in argument. The five kinds of rationales are compilation rationales, which can be represented without assuming domain-knowledge (such as utilities) beyond that normally required for argument. The principal thesis is that such rationales can be analyzed in a framework of argument not too different from what AI already has. The result is (...) a formal understanding of rationales, a partial taxonomy, and a foundation for computer programs that represent and reason with rationales.The five kinds of rationales are as follows: (c)ompression and (s)pecialization, which yield rules, and (d)isputation, which yields a decision. These are modeled as potentially changing the focus of the dispute. Then there are (f)it, a rationale for rules, and (r)esolution, a rationale for decisions. These cannot be modeled as simply; they force disputation to a meta-level, at least temporarily. (shrink)

Among Plato's later dialogues, the _Parmenides_ is one of the most significant. Not only a document of profound philosophical importance in its own right, it also contributes to the understanding of Platonic dialogues that followed it, and it exhibits the foundations of the physics and ontology that Aristotle offered in his _Physics_ and _Metaphysics _VII. In this book, R.E. Allen provides a superb translation of the _Parmenides_ along with a structural analysis that procedes on the assumption that formal elements, logical (...) and dramatic, are important to its interpretation and that the argument of the _Parmenides_ is aporetic, a statement of metaphysical perplexities. Allen's original translation of and commentary on the _Parmenides_ were published in 1983 to great acclaim and have now been revised by the author. (shrink)

H. Richard Nieburh's major work, which he did not live to complete, was to be on theological ethics. Based on the published and unpublished writings that Niebuhr completed during the last decade of his life, Roots of Relational Ethics demonstrates that Niebuhr's conception of responsibility was the culmination of his thought about self, God, Christ, the church, ethics and decision-making, and social evil. R. Melvin Keiser examines the limitations and potential of Niebuhr's use of responsibility in comparison with relevant themes (...) in liberation and feminist theological ethics. He suggests that Niebuhr's mature work can contribute to the alleviation of environmental exploitation, sexism, anti-Judaism, war, racism, and classism. (shrink)

A defence of the idea that there are sui generis duties of love: duties, that is, that we owe to people in virtue of standing in loving relationships with them. I contrast this non‐reductionist position with the widespread reductionist view that our duties to those we love all derive from more generic moral principles. The paper mounts a cumulative argument in favour of the non‐reductionist position, adducing a variety of considerations that together speak strongly in favour of adopting it. The (...) concluding section connects this debate with larger issues in moral theory concerning the general idea of obligation. (shrink)

In a detailed and careful manner, Taylor sets about an analysis of the notions of causation, human action, purpose, and a whole host of other conceptions such as deliberation, willing, mental acts, and reasons that relate to these key concepts in the philosophy of human action. The issue is, of course, what sort of explanation is suited to grasping the inherent intelligibility of human action. Having argued his way through to a notion of agent causality, which differs little from that (...) of Aristotle, and having concluded to the irreducibility of purpose that this conception implies, Taylor maintains that logical reductionism, behaviorism, and/or mechanism are logically deficient and leave human action unexplained; however, the non-reducibility of common sense, teleological and free will concepts does not imply, for Taylor, a dualism Taylor does leave it open as a matter to be empirically decided whether or not ontological reductionism is a viable alternative. While the book is an extraordinarily skillful and dialectical handling of current discussion in the philosophy of action, there is distressingly little mention of the sources and supports of this discussion. The effect is to make some of Taylor's more controversial pronouncements appear a bit more dogmatic than should be the case; but in the end, content triumphs sufficiently over style to make this book important reading for anyone interested in having some clear light thrown on the thorny problems surrounding the philosophy of action.—E. A. R. (shrink)

An important contribution to the philosophical inquiry on death. Ferrater Mora rescues the problem from the underground men of philosophy and places it in the ample yet fastidious perspective of reason. The first three chapters discuss "death" or "cessation" in inorganic, organic, and human nature. The last resumes the history of Western opinion on the subject. The subtitle, "an outline of an integrationist philosophy," indicates no facile eclecticism but a willingness to avoid absolutes. The main asset of this enormously learned (...) book is the brilliance with which the author leads us through a labyrinth of conflicting attitudes and presuppositions, always sustained by the dynamism of an inquiry in which doubt is not an abyss but a ground.--A. R. (shrink)

Taking the artistic return to "primitive symbols" to be a sign of renewed religious consciousness, Mr. Baird analyzes in detail the use and meaning of symbols in the work of Melville, Gaugin, Stevenson, and others who have travelled in the East. The author, who is much influenced by Jung and Langer, finds this atavistic return promising both artistically and culturally. An erudite work, critically perceptive, but far more valuable for its literary insights than for its psychological theses.--A. R.

Mauchaussat gives a detailed, chronological, and dense picture of Lachelier's thought and its milieu. He studies with erudition the connections with thinkers of analogous tendencies: Maine de Biran, Ravaisson, Boutroux, and Brunschvicg, and, outside the French tradition, Lachelier's relations and debts to Kant.--A. R.

From an examination of Leibniz's letters and papers, the author traces the influence of Spinoza on Leibniz, and considers the criticisms which Leibniz raised against Spinoza. There is an appendix on the scholastic and renaissance antecedents of the two philosophers.--A. R.

This is a "philosophic inquiry concerning the order of human existence in society and history." The first in a projected series of six volumes, it deals with the cosmological myth as the principle of organization in the imperialistic societies of ancient Mesopotamia and Egypt. The imbalance of such an order is diagnosed, and the emergence of the historical order of ancient Israel is analyzed. The order of history is also treated as manifesting itself in different modes of symbolizing: 1) the (...) participation in being, 2) the pre-occupation with the lasting and the passing, 3) the construction of symbols "to interpret the unknown by analogy with the really or supposedly known. The history of symbols is a progression from compact to differentiated experiences and symbols."--A. R. (shrink)

This voluminous treatise develops a "temporal" theory of knowledge out of the basic premisses of Sein und Zeit. It depends completely on Heidegger, aping his style as well as his terminology.--A. R.

This book attempts to place the problems of logic, epistemology, science, history, and ethics on a new scientific basis.--A. R.

A study of Blake's poetry and its use of Kabalistic imagery to depict the fall of man to selfhood and the hope of regeneration through the "sweet science" of imagination.--A. R.

Fifty two scholars from the east and west have contributed essays to this volume presented to T. M. P. Mahadevan, head of the Department of Philosophy, University of Madras on his fiftieth birthday. Although the range of papers is broad, collectively they present an overview of the diverse currents in traditional and contemporary Indian philosophy. A bibliography of Mahadevan's writings is also included.—R. J. B.

Based on personal acquaintance with the master and a study of his works, this book provides an excellent introduction to the thought of one of the great spiritual leaders of our time. A. Basu contributes a helpful foreword.--D. R.

A cooperative study of the development of Buddhism by eleven top Buddhist scholars. It is about as comprehensive in scope and accurate in detail as one could hope for within any one volume. While each contributor is responsible for his own chapter, the book forms a single, homogeneous whole.--D. R.

A sane, practical guide to the art of meditation by a Swiss trained in Buddhism. The preliminaries are patiently and clearly dealt with and it is p. 112 before the author indicates that "meditation can now begin." Despite the Buddhist background, no religious commitment is presupposed. The approach is psychologically sound, the treatment free from obscurantism, and the manner engaging.--D. R.

A systematic effort to state and answer the classical problems of moral philosophy, including that of the metaphysical foundations of morals. The outline of problems and the general position argued is reminiscent of Kant's Grundlegung; like Kant, Mr. Raphael locates the essence of morality in the recognition that human personality, including the ability to choose freely, is an "evil in itself." Even more than Kant, however, he is doubtful of demonstrating the force of this conception of morality by rational argument.--R. (...) H. (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)

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

Eight articles written by members of the Tulane philosophy department. The contributions range from a discussion of classifications of supposition in medieval logic by Louise Nisbet Roberts and a comparatively lengthy consideration of the relationship between universals and individuals by James K. Feibleman to an attempt by Paul G. Morrison to clarify in a restricted system the expressions, 'invariance,' 'homogeneity,' and 'heterogeneity.'--R. P.

A defense of the value of a liberal education to young people interested in entering the modern field of corporate management.--R. P.

With these two thick volumes Thorndike's well-known history reaches its conclusion in the 17th century. The century is seen, not as a period in which science replaces magic, but as one in which old magic gives way to new.--R. P.

"Why are there essents rather than nothing?" is the central question of this work. Heidegger here uncovers the meaning of "being" and the history of man's understanding of "being," mainly through a discussion of the origin and overtones of the pertinent Greek and German terms. The style is difficult; the translation on the whole satisfactory.--R. D. G.

This edition makes available the author's privately printed Course of Lectures on Aesthetics, a 1920 article, "Mind and Medium in Art," in which appreciation and creation are sharply distinguished, and his well known, but already reprinted, article on "Psychical Distance." The author held that the future of aesthetics lies in psychology, and argues in his Lectures that aesthetics is the systematic attitude which "man takes up vis-à-vis human life."--R. P.

A competent systematic exposition, following the accounts of Couturat and Lewis.--R. W.

An attempt to defend Bultmann's existentialist re-interpretation of Protestant Theology against its critics. The major areas of disagreement center around the existentialists' rejection of the subject-object scheme in epistemology, rival conceptions of history, and the relation of faith to the Bible as an historical document. Provides an interesting view of the troubled waters of contemporary Protestant Theology.--R. G. S.

Treatises of this length and care are rarely written today and in the course of Cumming's explorations there is an enormous richness of insight, commentary, and analysis of the history of liberal thought. But at the same time, it is difficult to keep the main themes of this study in clear focus. One gets the impression that Cumming originally set out to understand liberal thought as expressed by John Stuart Mill and found himself digging into origins. Dig he does, taking (...) into account in his intellectual journey through Western Civilization: Polybius, Cicero, Augustine, Petrarch, Machiavelli, Hobbes, Locke, Hume, Bentham, James Mill and many others along the way. One can learn a great deal about this western political tradition by following Cumming's patient explications and critiques. In the foreground is always John Stuart Mill and at times Cumming fosters the misimpression that Mill culminates this entire tradition. Yet Cumming's attitude toward Mill is strangely ambivalent and toward the end of this study, Cumming seems to be more fascinated with the stages of Mill's development and his mental crisis rather than with the integrity and coherence of his political philosophy. Liberal political thought has recently come in for a severe polemical thrashing and Cumming's study might have been a detailed, eloquent defense of this tradition. But the study is deficient in attempting to show how liberal thought can directly meet the numerous criticisms that have been raised from many sides. In the preface, Cumming reports that the manuscript was on the way to the typesetters during the upheaval at Columbia when police arrived on campus. This episode symbolizes the strange feeling one has that the book is dated by the time it appeared. Despite its weaknesses as an apology for liberal thought, it excels in making us sensitive to its long and vital history.--R. J. B. (shrink)

The acquisition by the Bodleian Library in 1948 of the Lovelace papers has made possible a number of historically oriented papers on Locke and his philosophy, e.g., J. Yolton's John Locke and the Way of Ideas, J. W. Gough's, Locke's Political Philosophy, and W. v.Leyden's publication of the Essays on the Law of Nature. Cranston's biography is a distinguished addition to this list: it makes full use of the source material and is as thorough as one could ask in revealing (...) the concerns--especially political concerns --of Locke's life. It is rather less satisfactory in its treatment of his epistemological development. --R. F. T. (shrink)

The author explores Aristotle’s theory of signification by contrasting it to Plato’s theory of language, which is interpreted, rather uncritically, as a theory of "natural" signification. She discusses Aristotle’s position on the meaning of sentences and sentential parts, and his theory of reference. She then considers Aristotle’s concept of philosophical language as the language of demonstration, in contrast to the saying of myths, and compares apodeixis to rhetoric and poetry. "Clarity" is required in philosophical discourse, and is defined by contrast (...) with equivocation, ambiguity and metaphor. It is good to have a collection of Aristotle’s remarks on these important items, but the author seems not to draw much philosophical capital from them: "clarity" seems to be taken as little more than "careful writing." Finally some passages from the Metaphysics are examined to give an example of how Aristotle uses language in philosophy. The book contains interesting remarks, but the general problem seems misplaced: we are to be shown that Aristotle is "not concerned solely with linguistic clarification but with positive knowledge of nonlinguistic reality", but such a dichotomy is certainly not Aristotelian. Neither is the problem raised in this sentence, "It is difficult to say whether Aristotle thinks men are social because they have the power of speech or the converse". Again, the author says "poetry is the imitation of things" when she means tragedy is the imitation of action.—R. S. (shrink)

A survey of the history of the ideal of a balance between man and nature in America, this book outlines the development of the conservation movement and summarizes the thinking of such men as Thoreau. One misses a critical discussion of the men and ideas opposed by the conservationists, e.g., Carnegie. The discussion of contemporary problems, the population-explosion and the arms race, is provocative but less careful and well-documented than the rest of the book.—R. J. W.

A collection of discussions of Descartes' philosophy, ranging from Gassendi to Ryle. Since it brings together a considerable amount of relevant material, it may prove useful as a pedagogical supplement to the Meditations.—R. J. W.

In this group of well-written essays Randall discusses explicitly the group of ideas which have been implicit in his earlier works in intellectual history. The first section, which deals with the philosophy of history, argues that particular things have particular histories, and that these histories belong to them on the basis of what they are taken to be and expected to become. The metaphysics of the second section is a pluralistic analysis of actual experience and its symbolic representation.--R. F. T.

Convinced of the truth of materialism, which he associates with a "leftist" political outlook, the author argues that traditional philosophic, religious, and artistic insights ought nevertheless to be preserved, by retaining old words and emotions stripped of their supernatural and idealistic associations.--R. H.

The author--biologist, physiologist, and psychologist--shows the limitations of the all-too-scientific approaches to the human being, and argues effectively that "psychology requires an ontological interpretation of human existence." Psychology and philosophy must return to the living subject as their basis, the subject as self-and-context. The ultimate meaning of "physiological" pain lies in the person's disposition towards pain and his consequent reactions to its occurrence. Although he does not discuss abstract phenomenological principles, he works in an altogether phenomenological way, and throughout the (...) book enlightens the continuous path between man, the object of scientific study, and man, the subject in an ethical world.--R. C. D. (shrink)

In examining Kant's Foundations for the Metaphysics of Morals, Duncan contrasts his own, Critical interpretation with the Ethical interpretation which is far more common. His principal contention is that the Foundations is not an exposition of Kant's ethical views but a "partial critique of practical reason"; Kant's object "is to understand the nature of morality and to state its principle, that is, the principle which describes what morality is." The net effect of this approach is to take the emphasis away (...) from the categorical imperative as a criterion of morality and to place it on parts of the Foundations which are inherently stronger, particularly on Sections I and III. At the same time it brings the Foundations closer to the first and second Critiques and makes it a sounder and more thoroughly Kantian work.--R. F. T. (shrink)

Although political theory was pronounced dead only a few short years ago, this collection of articles shows that much life is left in contemporary political theory. Based on a symposium concerning human rights held at the Sixth World Congress of the International Political Science Association held at Geneva in 1964, the collection includes papers by Macpherson, Polin, Chapman, Cranston, Raphael, Mayo, Schneider, and Fawcett. Macpherson and Polin set the context by exploring the concept of rights in Hobbes and Locke. While (...) the other papers have an eye on traditional discussions, they are also concerned with exploring what "rights" does and can mean in the contemporary world. The international gathering of authors brings together diverse points of view on the common problem of human rights.--R. J. B. (shrink)
