Moral anti-realism comes in two forms – noncognitivism and the error theory. The noncognitivist says that when we make moral judgments we aren’t even trying to state moral facts. The error theorist says that when we make moral judgments we are making statements about what is objectively good, bad, right, or wrong but, since there are no moral facts, our moral judgments are uniformly false. This development of moral anti-realism was first seriously defended by John Mackie. In this paper I (...) explore a dispute among moral error theorists about how to deal with false moral judgments. The advice of the moral abolitionist is to stop making moral judgments, but the contrary advice of the moral fictionalist is to retain moral language and moral thinking. After clarifying the choice that arises for the moral error theorist, I argue that moral abolitionism has much to recommend it. I discuss Mackie’s defense of moral fictionalism as well as a recent version of the same position offered by Daniel Nolan, Greg Restall, and Caroline West. Then I second some remarks Ian Hinckfuss made in his defense of moral abolitionism and his criticism of “the moral society.” One of the worst things about moral fictionalism is that it undermines our epistemology by promoting a culture of deception. To deal with this problem Richard Joyce offers a “non-assertive” version of moral fictionalism as perhaps the last option for an error theorist who hopes to avoid moral abolitionism. I discuss some of the problems facing that form of moral fictionalism, offer some further reasons for adopting moral abolitionism in our personal lives, and conclude with reasons for thinking that abolishing morality may be an essential step in achieving the goals well-meaning moralists and moral fictionalists have always cherished.

In line with the British Psychological Society's recent recommendations for teaching the history of psychology, this comprehensive undergraduate textbook emphasizes the philosophical, cultural and social elements that influenced psychology's development. The authors demonstrate that psychology is both a human (e.g. psychoanalytic or phenomenological) and natural (e.g. cognitive) science, exploring broad social-historical and philosophical themes such as the role of diverse cultures and women in psychology and the complex relationship between objectivity and subjectivity in the development of psychological knowledge. The result (...) is a fresh and balanced perspective on what has traditionally been viewed as the collected achievements of a few 'great men'. With a variety of learning features, including case studies, study questions, thought experiments and a glossary, this new textbook encourages students to critically engage with chapter material and analyze themes and topics within a social, historical and philosophical framework.

Written by leading experts in the field, Stellar Spectral Classification is the only book to comprehensively discuss both the foundations and most up-to-date techniques of MK and other spectral classification systems. Definitive and encyclopedic, the book introduces the astrophysics of spectroscopy, reviews the entire field of stellar astronomy, and shows how the well-tested methods of spectral classification are a powerful discovery tool for graduate students and researchers working in astronomy and astrophysics. The book begins with a historical survey, followed by (...) chapters discussing the entire range of stellar phenomena, from brown dwarfs to supernovae. The authors account for advances in the field, including the addition of the L and T dwarf classes; the revision of the carbon star, Wolf-Rayet, and white dwarf classification schemes; and the application of neural nets to spectral classification. Copious figures illustrate the morphology of stellar spectra, and the book incorporates recent discoveries from earth-based and satellite data. Many examples of spectra are given in the red, ultraviolet, and infrared regions, as well as in the traditional blue-violet optical region, all of which are useful for researchers identifying stellar and galactic spectra. This essential reference includes a glossary, handy appendixes and tables, an index, and a Web-based resource of spectra. In addition to the authors, the contributors are Adam J. Burgasser, Margaret M. Hanson, J. Davy Kirkpatrick, and Nolan R. Walborn. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:212 HISTORY OF PHILOSOPHY with Gassendi and his studies on atomism. Yet Papi gives us very little which is not already generally known. There is but a mere hint of how atomistic philosophy was handled by the Aristotelians and to what extent they actually absorbed some of that tradition themselves. Nothing in detail is said of the process whereby atomistic and Platonic motives became coupled, not only by Bruno, (...) but by Ficino before and by Cudworth afterwards. On the credit side, however, the author does call attention to the commentary and paraphrase of Lucretius by Girolamo Frachetta of Rovigo (printed 1589), a work of some interest, which has been but little studied. Such rays of light are all too infrequent in this section and Papi is usually content to follow the conventional beaten path. For one to write a book on Bruno which breaks new ground is now difficult, for the field has been so thoroughly worked over. This one takes up a number of interesting themes found in Bruno's writings and sheds some light on them, but it seldom if ever says anything very different from the well-established tradition of Bruno scholarship in Italy which has produced so many mediocre books over the years. The specialist on Bruno and the sixteenth century will find little to detain him; the more casual reader could be ~rected to a number of superior treatments of various aspects of the Nolan's thought. In short, this study adds but little to what is already known. CHAm~V_SB. ScH~rrr University of Leeds Sir Walter Ralegh dcrivain, l'~uvre et les iddes. By Pierre Lefranc. (Qutbec: Les Presses de l'Universit~ Laval, 1968. Pp. 733. $19.50) This excellent study, the fruit of more than a dozen years of research, throws much light on Ralegh's thought and literary achievement. Lefranc has examined the manuscript sources, and unearthed quite a few new ones, and has patiently, carefully, and with much detective work, established what is no doubt the best available hypothesis of what is authentic among Ralegh's purported prose and poetic writings, and the date and circumstances of their composition. He has analyzed them in the context of Ralegh's carver, and has developed an exciting and rich interpretation of his political, philosophical and religious ideas. Ralegh's role in intellectual history derives mainly from his reputation as a Machiavellian, as an atheist, and from his mammoth, "pious," much-read providential History of the World (written during his years as a prisoner in the Tower of London). Lefranc deftly sorts and weighs the evidence for the various views and attitudes attributed to Ralegh in his own day and by interpreters ever since, and emerges from this examination with a fresh and striking picture of one of the liveliest bridge figures between the Elizabethan Renaissance and the modern world. The establishment of the canon leads to discarding as not by Ralegh many writings that have previously been used in interpreting the courtier's views. Three philosophical works which have played a role in twentieth-century interpretation, "A Treatise of the Soule," "The Prince, or Maxims of State" and "The Sceptick" are shown to be doubtful to a greater or lesser degree. "The Sceptick," which Strathmann (Sir Walter Ralegh,,4 Study in Elizabethan Skepticism, New York, 1951) had used to interpret Ralegh as a sceptical-Christian fideist, had been questioned earlier by Lefranc, Sprott, and myself. It is just a translation of portions of Book I of Sextus F_znpiricus' Outlinea of Pyrrhonism, and contains no connection with Ralegh, except that it was BOOK REVIEWS 213 published in his literary remains in 1651. Lefranc now, examining the evidence of the four manuscripts that have been discovered, concludes that it was a part of Ralegh's documentation when he was doing his research, but that 'Tattribution de 'The Sceptick' Ralegh lui-m~me ne repose sur rien" (p. 67). With the canon shorn of the dubious items, Lefranc proceeds to unfold a picture of Ralegh's intellectual world. As a practical statesman, buccaneer and explorer, Ralegh had a view of the role England should play vis-,'t-vis Spain and the New World that contained... (shrink)

In Minkowski spacetime, because of the relativity of simultaneity to the inertial frame chosen, there is no unique world-at-an-instant. Thus the classical view that there is a unique set of events existing now in a three dimensional space cannot be sustained. The two solutions most often advanced are that the four-dimensional structure of events and processes is alone real, and that becoming present is not an objective part of reality; and that present existence is not an absolute notion, but is (...) relative to inertial frame; the world-at-an-instant is a three dimensional, but relative, reality. According to a third view, advanced by Robb, Capek and Stein, what is present at a given spacetime point is, strictly speaking, constituted by that point alone. I argue here against the first of these views that the four-dimensional universe cannot be said to exist now, already, or indeed at any time at all; so that talk of its existence or reality as if that precludes the existence or reality of the present is a non sequitur. The second view assumes that in relativistic physics time lapse is measured by the time co-ordinate function; against this I maintain that it is in fact measured by the proper time, as I argue by reference to the Twin Paradox. The third view, although formally correct, is tarnished by its unrealistic assumption of point-events. This makes it susceptible to paradox, and also sets it at variance with our normal intuitions of the present. I argue that a defensible concept of the present is nonetheless obtainable when account is taken of the non-instantaneity of events, including that of conscious awareness, as that region of spacetime comprised between the forward lightcone of the beginning of a small interval of proper time t and the backward lightcone of the end of that interval. This gives a serviceable notion of what is present to a given event of short duration, as well as saving our intuition of the “reality” or robustness of present events. (shrink)

"This is an excellent textbook on Neoplatonism which gives the reader a very concise and lucid overview of the basic doctrines and leading thinkers of the last great philosophy to emerge before the Christianization of the Roman Empire. I’ve no doubt that my students next semester will benefit from the analyses contained in the book. The contents of the chapters are very informative and adequately place developments in their socio-cultural context." --Michael B. Simmons, Auburn University at Montgomery.

It is commonly held that there is no place for the 'now’ in physics, and also that the passing of time is something subjective, having to do with the way reality is experienced but not with the way reality is. Indeed, the majority of modern theoretical physicists and philosophers of physics contend that the passing of time is incompatible with modern physical theory, and excluded in a fundamental description of physical reality. This book provides a forceful rebuttal of such claims. (...) In successive chapters the author explains the historical precedents of the modern opposition to time flow, giving careful expositions of matters relevant to becoming in classical physics, the special and general theories of relativity, and quantum theory, without presupposing prior expertise in these subjects. Analysing the arguments of thinkers ranging from Aristotle, Russell, and Bergson to the proponents of quantum gravity, he contends that the passage of time, understood as a local becoming of events out of those in their past at varying rates, is not only compatible with the theories of modern physics, but implicit in them.

In the transition to Einstein’s theory of Special Relativity (SR), certain concepts that had previously been thought to be univocal or absolute properties of systems turn out not to be. For instance, mass bifurcates into (i) the relativistically invariant proper mass m0, and (ii) the mass relative to an inertial frame in which it is moving at a speed v = βc, its relative mass m, whose quantity is a factor γ = (1 – β2) -1/2 times the proper mass, (...) m = γm0.

Previous work suggests that threat-related stimuli are stored to a greater degree in working memory compared to neutral stimuli. However, most of this research has focused on stimuli with physically salient threat attributes, failing to account for how a “neutral” stimulus that has acquired threat-related associations through differential aversive conditioning influences working memory. The current study examined how differentially conditioned safe and threat stimuli are stored in working memory relative to a novel, non-associated stimuli. Participants completed a differential fear conditioning (...) task followed by a change detection task consisting of three conditions across two loads. Results revealed individuals successfully learned to distinguishing CS+ from CS– conditions during the differential aversive conditioning task. Our working memory outcomes indicated successful load manipulation effects, but no statistically significant differences in accuracy, response time, or Pashler’s K measures of working memory capacity between CS+, CS–, or N conditions. However, we observed significantly reduced RT difference scores for the CS+ compared to CS– condition, indicating greater RT differences between the CS+ and N condition vs. the CS– and N condition. These findings suggest that differentially conditioned stimuli have little impact on behavioral outcomes of working memory compared to novel stimuli that had not been associated with previous safe of aversive outcomes, at least in healthy populations.

Philosophers have constituted business ethics as a field by providing a systematic overview that interrelates its problems and concepts and that supplies the basis for building on attained results. Is there a properly theological task in business ethics? The religious/theological literature on business ethics falls into four classes: (1) the application of religious morality to business practices; (2) the use of encyclical teachings about capitalism; (3) the interpretation of business relations in agapa-istic terms; and (4) the critique of business from (...) a liberation theological point of view. Theologians have not adequately addressed the questions of whether there are particular theological tasks in the field as they define it, and whether, if they define it, the theological definition is different from the philosophical.

Before establishing his mature interpretation of infinitesimals as fictions, Gottfried Leibniz had advocated their existence as actually existing entities in the continuum. In this paper I trace the development of these early attempts, distinguishing three distinct phases in his interpretation of infinitesimals prior to his adopting a fictionalist interpretation: (i) (1669) the continuum consists of assignable points separated by unassignable gaps; (ii) (1670-71) the continuum is composed of an infinity of indivisible points, or parts smaller than any assignable, with no (...) gaps between them; (iii) (1672- 75) a continuous line is composed not of points but of infinitely many infinitesimal lines, each of which is divisible and proportional to a generating motion at an instant (conatus). In 1676, finally, Leibniz ceased to regard infinitesimals as actual, opting instead for an interpretation of them as fictitious entities which may be used as compendia loquendi to abbreviate mathematical reasonings.

This book gathers together for the first time an important body of texts written between 1672 and 1686 by the great German philosopher and polymath Gottfried Leibniz. These writings, most of them previously untranslated, represent Leibniz's sustained attempt on a problem whose solution was crucial to the development of his thought, that of the composition of the continuum. The volume begins with excerpts from Leibniz's Paris writings, in which he tackles such problems as whether the infinite division of matter entails (...) perfect points, whether matter and space can be regarded as true wholes, whether motion is truly continuous, and the nature of body and substance. Comprising the second section is Pacidius Philalethi, Leibniz's brilliant dialogue of late 1676 on the problem of the continuity of motion. In the selections of the final section, from his Hanover writings of 1677-1686, Leibniz abandons his earlier transcreationism and atomism in favor of the theory of corporeal substance, where the reality of body and motion is founded in substantial form or force.Leibniz's texts (one in French, the rest in Latin) are presented with facing-page English translations, together with an introduction, notes, appendixes containing related excerpts from earlier works by Leibniz and his predecessors, and a valuable glossary detailing important terms and their translations.

Evaluation of the influence of Hayden White on the theory of history is made difficult by his preference for the essay form, valued for its experimental character, and by the need to find comparable data. A quantitative study of citations of his work in English and foreign-language journals, 1973–1993, reveals that although historians were prominent among early readers of Metahistory, few historical journals reviewed White's two subsequent collections of essays and few historians-except in Germany-cited them. Those historians who did tended (...) still to cite Metahistory and often the parts of it devoted specifically to nineteenth-century historians.Literary critics, on the other hand, were relatively late to discover White, but during the "narrative turn" of the 1970s and 1980s his work was important for students of the novel and the theater. Recognition of it was especially marked in Spanish-speaking countries and in Germany.As a result, salient themes of White's later work-the ideological and political import of narrativization, the "historical sublime," and writing in the "middle voice"-have largely gone unremarked by historians and philosophers. Both these groups have tended to be irritated by White's bracketing of questions of historical epistemology; some have accused him of effacing the line between fiction and history, while White's numerous literary readers have generally applauded his tendencies in this direction. White however has consistently maintained that there is a difference, although not the one conventionally postulated. His exploration of writing in the "middle voice" brings his work full circle, in that it promises a "modernist" realism appropriate for representing the "sublime" events of our century. (shrink)

This paper consists in a study of Leibniz’s argument for the infinite plurality of substances, versions of which recur throughout his mature corpus. It goes roughly as follows: since every body is actually divided into further bodies, it is therefore not a unity but an infinite aggregate; the reality of an aggregate, however, reduces to the reality of the unities it presupposes; the reality of body, therefore, entails an actual infinity of constituent unities everywhere in it. I argue that this (...) depends on a generalized notion of aggregation, according to which a thing may be an aggregate of its constituents if every one of its actual parts presupposes such constituents, but is not composed from them. One of the premises of this argument is the reality of bodies. If this premise is denied, Leibniz’s argument for the infinitude of substances, and even of their plurality, cannot go through.

In contrast with some recent theories of infinitesimals as non-Archimedean entities, Leibniz’s mature interpretation was fully in accord with the Archimedean Axiom: infinitesimals are fictions, whose treatment as entities incomparably smaller than finite quantities is justifiable wholly in terms of variable finite quantities that can be taken as small as desired, i.e. syncategorematically. In this paper I explain this syncategorematic interpretation, and how Leibniz used it to justify the calculus. I then compare it with the approach of Smooth Infinitesimal Analysis, (...) as propounded by John Bell. I find some salient differences, especially with regard to higher-order infinitesimals. I illustrate these differences by a consideration of how each approach might be applied to propositions of Newton’s Principia concerning the derivation of force laws for bodies orbiting in a circle and an ellipse. “If the Leibnizian calculus needs a rehabilitation because of too severe treatment by historians in the past half century, as Robinson suggests (1966, 250), I feel that the legitimate grounds for such a rehabilitation are to be found in the Leibnizian theory itself.”—(Bos 1974–1975, 82–83).

It is well known that Leibniz advocated the actual infinite, but that he did not admit infinite collections or infinite numbers. But his assimilation of this account to the scholastic notion of the syncategorematic infinite has given rise to controversy. A common interpretation is that in mathematics Leibniz’s syncategorematic infinite is identical with the Aristotelian potential infinite, so that it applies only to ideal entities, and is therefore distinct from the actual infinite that applies to the actual world. Against this, (...) I argue in this paper that Leibniz’s actual infinite, understood syncategorematically, applies to any entities that are actually infinite in multitude, whether numbers, actual parts of matter, or monads. It signifies that there are more of them than can be assigned a number, but that there is no infinite number or collection of them, which notion involves a contradiction. Similarly, to say that a magnitude is actually infinitely small in the syncategorematic sense is to say that no matter how small a magnitude one takes, there is a smaller, but there are no actual infinitesimals. In geometry one may calculate with expressions apparently denoting such entities, on the understanding that they are fictions, standing for variable magnitudes that can be made arbitrarily small, so as to produce demonstrations that there is no error in the resulting expressions.

The reappearance of the question of moral judgments by historians makes a reappraisal of the issues timely. Almost all that has been written on the subject addresses only the propriety of moral judgments in the written texts historians produce. However, historians have to make moral choices when selecting a subject upon which to write; and they make a tacit moral commitment to write and teach honestly. Historians usually dislike making explicit moral evaluations, and have little or no training in how (...) to do so. They can argue it’s not their job; they are only finders of fact. Historians holding a determinist view of actions do not think it appropriate to blame people for doing what they couldn’t help doing; for those believing there is an overall pattern to history, individual morality is beside the point. Finally, since earlier cultures had values different from ours, it seems unjust to hold them to contemporary standards. This essay modifies or rejects these arguments. Some historians have manifested ambivalence, acknowledging it is difficult or impossible to avoid making moral evaluations . Ordinary-language philosophers, noting that historiography has no specialized vocabulary, see it as saturated by the values inherent in everyday speech and thought. I argue that the historicist argument about the inevitably time-bound limitation of all values is exaggerated. Historians who believe in the religious grounding of values obviously disagree with it; but even on a secular level, morals are often confused with mores. If historians inevitably make moral evaluations, they should examine what philosophical ethicists—virtue ethicists, deontologists, and consequentialists—have said about how to make them; and even if they find no satisfactory grounding for their own moral attitudes, it is a brute fact that they have them. I end with an argument for “strong evaluations”—neither treating them as a troublesome residue in historiography nor, having despaired of finding a solid philosophical ground for moral evaluations, concluding that they are merely matters of taste. I believe historians should embrace the role of moral commentators, but that they should be aware that their evaluations are, like all historical judgments, subject to the criticisms of their colleagues and readers. Historians run little risk of being censorious and self-righteous; the far greater danger is acquiescing in or contributing to moral confusion and timidity. (shrink)

In lively and readable prose, Arthur presents a new approach to the study of logic, one that seeks to integrate methods of argument analysis developed in modern “informal logic” with natural deduction techniques. The dry bones of logic are given flesh by unusual attention to the history of the subject, from Pythagoras, the Stoics, and Indian Buddhist logic, through Lewis Carroll, Venn, and Boole, to Russell, Frege, and Monty Python. A previous edition of this book appeared under the title _Natural (...) Deduction_. This new edition adds clarifications of the notions of explanation, validity and formal validity, a more detailed discussion of derivation strategies, and another rule of inference, Reiteration.

The development of Louis Mink's philosophy of history is traced beginning with his classic essay "The Autonomy of Historical Understanding" and culminating in "Narrative Form as a Cognitive Instrument". Mink's thoughts on history during this period were marked by an everdeepening interest in the textuality and intertextuality of historical accounts, in the modes of representation which historians adopt and use to produce their "reality effects," and in the effort to mediate between what he was to call the New Rhetorical Relativism (...) and the claim that histories are in some sense true. Mink's response to Hempel's "The Function of General Laws in History," the beginning of Mink's consideration of narrative in "The Autonomy of Historical Understanding" and later in "History and Fiction as Modes of Comprehension," his association with Hayden White, his critique of a paper by Arno Mayer, and the beginning of Mink's final thoughts in "History and Narrative" and "Narrative Form as a Cognitive Instrument" are considered in elaborating the development of Mink's philosophy of history.

In this paper I try to sort out a tangle of issues regarding time, inertia, proper time and the so-called “clock hypothesis” raised by Harvey Brown's discussion of them in his recent book, Physical Relativity. I attempt to clarify the connection between time and inertia, as well as the deficiencies in Newton's “derivation” of Corollary 5, by giving a group theoretic treatment original with J.-P. Provost. This shows how both the Galilei and Lorentz transformations may be derived from the relativity (...) principle on the basis of certain elementary assumptions regarding time. I then reflect on the implications of this derivation for understanding proper time and the clock hypothesis. (shrink)

In this paper I offer a fresh interpretation of Leibniz’s theory of space, in which I explain the connection of his relational theory to both his mathematical theory of analysis situs and his theory of substance. I argue that the elements of his mature theory are not bare bodies (as on a standard relationalist view) nor bare points (as on an absolutist view), but situations. Regarded as an accident of an individual body, a situation is the complex of its angles (...) and distances to other co-existing bodies, founded in the representation or state of the substance or substances contained in the body. The complex of all such mutually compatible situations of co-existing bodies constitutes an order of situations, or instantaneous space. Because these relations of situation change from one instant to another, space is an accidental whole that is continuously changing and becoming something different, and therefore a phenomenon. As Leibniz explains to Clarke, it can be represented mathematically by supposing some set of existents hypothetically (and counterfactually) to remain in a fixed mutual relation of situation, and gauging all subsequent situations in terms of transformations with respect to this initial set. Space conceived in terms of such allowable transformations is the subject of Analysis Situs. Finally, insofar as space is conceived in abstraction from any bodies that might individuate the situations, it encompasses all possible relations of situation. This abstract space, the order of all possible situations, is an abstract entity, and therefore ideal. (shrink)

In this paper I attempt to throw new light on Leibniz's apparently conflicting remarks concerning the continuity of matter. He says that matter is "discrete" yet "actually divided to infinity" and (thus dense), and moreover that it fills (continuous) space. I defend Leibniz from the charge of inconsistency by examining the historical development of his views on continuity in their physical and mathematical context, and also by pointing up the striking similarities of his construal of continuity to the approach taken (...) by 20th century Combinatorial Topology.
