It has been claimed that Massimi’s recent perspectival approach to science sits in tension with a realist stance. I shall argue that this tension can be defused in the quantum context by recasting Massimi’s perspectivalism within a phenomenological framework. I shall begin by indicating how the different but complementary forms of the former are manifested in the distinction between certain so-called ‘-epistemic’ and ‘-ontic’ understandings of quantum mechanics, namely QBism and Relational Quantum Mechanics, respectively. A brief consideration of Dieks’ perspectivism (...) will then lead to a consideration of the much-maligned and typically dismissed role of the observer in the measurement process. This opens the door to London and Bauer’s presentation of a form of ‘phenomenological quantum perspectivalism’ that brings together Massimi’s two forms and explicitly eschews the ‘naïve’ realism that creates the above tension. I shall conclude with some reflections on how intersubjectivity can still be established within this framework, focusing in particular on how Massimi’s idea of ‘interlacing’ scientific perspectives can be accommodated, using the example of a ‘new cosmopolitanism’ that gave rise to Bose-Einstein statistics.

Steven French and Decio Krause examine the metaphysical foundations of quantum physics. They draw together historical, logical, and philosophical perspectives on the fundamental nature of quantum particles and offer new insights on a range of important issues. Focusing on the concepts of identity and individuality, the authors explore two alternative metaphysical views; according to one, quantum particles are no different from books, tables, and people in this respect; according to the other, they most certainly are. Each view comes with (...) certain costs attached and after describing their origins in the history of quantum theory, the authors carefully consider whether these costs are worth bearing. Recent contributions to these discussions are analyzed in detail and the authors present their own original perspective on the issues. The final chapter suggests how this perspective can be taken forward in the context of quantum field theory. (shrink)

Implicit Learning and Consciousness challenges conventional wisdom and presents the most up-to-date studies to define, quantify and test the predictions of the main models of implicit learning. The chapters include a variety of research from computer modeling, experimental psychology and neural imaging to the clinical data resulting from work with amnesics. The result is a topical book that provides an overview of the debate on implicit learning, and the various philosophical, psychological and neurological frameworks in which it can be placed. (...) It will be of interest to undergraduates, postgraduates and the philosophical, psychological and modeling research community. (shrink)

This is the first anthology to take a theoretical look at violence against women. Each essay shows how philosophy provides a powerful tool for examining a difficult and deep-rooted social problem. Stanley G. French, Wanda Teays, and Laura M. Purdy, all philosophers, present a familiar phenomenon in a new and striking fashion. The editors employ a two-tiered approach to this vital issue. Contributors consider both interpersonal violence, such as rape and battering; and also systemic violence, such as sexual harassment, (...) pornography, prostitution, and violence in a medical context. The editors have further broadened the discussion to include such cross-cultural issues as rape in war, dowry deaths, female genital mutilation, and international policies on violence against women. Against this wide range of topics, which integrate personal perspectives with the philosophical, the contributors offer powerful analyses of the causes and effects of violence against women, as well as potential policies for effecting change.

In recent years naturalism has become a focal point in the discussions of many contemporary philosophers. Philosophical Naturalism in the series Midwest Studies in Philosophy offers a broad sampling of previously unpublished essays that represent the current status of discussions of naturalism.

The 21 essays collected in this volume of Midwest Studies in Philosophy question and debate the primary assumptions of science. These are its conception of an orderly universe; its ability to define; and its ability to explain. The contributors approach these topics from varying perspectives, including the historic development of our understanding of the scientific enterprise; the controversy of opposing paradigms; and the challenges raised by quantum mechanics.

he relationship between metaphysics and science has recently become the focus of increased attention. Ladyman and Ross, in particular, have accused even naturalistically inclined metaphysicians of pursuing little more than the philosophy of A-level chemistry and have suggested that analytic metaphysics should simply be discontinued. In contrast, we shall argue, first of all, that even metaphysics that is disengaged from modern science may offer a set of resources that can be appropriated by philosophers of physics in order to set physics (...) within an interpretational framework. Secondly, however, we shall urge that insofar as metaphysics is intended to be more than just a toolbox it needs to accommodate the implications of physics if many of its core claims are to be sustained. We shall illustrate this last point with a discussion of the nature of laws and modality in the context of modern physics. (shrink)

Many important explanations in physics are based on ideas and assumptions about symmetries, but little has been said about the nature of such explanations. This chapter aims to fill this lacuna, arguing that various symmetry explanations can be naturally captured in the spirit of the counterfactual-dependence account of Woodward, liberalized from its causal trappings. From the perspective of this account symmetries explain by providing modal information about an explanatory dependence, by showing how the explanandum would have been different, had the (...) facts about an explanatory symmetry been different. Furthermore, the authors argue that such explanatory dependencies need not be causal. (shrink)

Many contemporary theorists charge that naïve realists are incapable of accounting for illusions. Various sophisticated proposals have been ventured to meet this charge. Here, we take a different approach and dispute whether the naïve realist owes any distinctive account of illusion. To this end, we begin with a simple, naïve account of veridical perception. We then examine the case that this account cannot be extended to illusions. By reconstructing an explicit version of this argument, we show that it depends critically (...) on the contention that perceptual experience is diaphanous, or more minimally and precisely, that there can be no difference in phenomenal properties between two experiences without a difference in the scenes presented in those experiences. Finding no good reason to accept this claim, we develop and defend a simple, naïve account of both veridical perception and illusion, here dubbed Simple, Austere Naïve Realism. (shrink)

Stein once urged us not to confuse the means of representation with that which is being represented. Yet that is precisely what philosophers of science appear to have done at the meta-level when it comes to representing the practice of science. Proponents of the so-called ‘syntactic’ view identify theories as logically closed sets of sentences or propositions and models as idealised interpretations, or ‘theoruncula, as Braithwaite called them. Adherents of the ‘semantic’ approach, on the other hand, are typically characterised as (...) taking them to be families of models that are set-theoretic, according to Suppes and others, or abstract, as Giere has argued. da Costa and French (Science and Partial Truth. OUP, Oxford, 2003) suggested that we should refrain from ontological speculation as to the nature of scientific theories and models and focus on their appropriate representation for various purposes within the philosophy of science. Such an approach allows both linguistic and non-linguistic resources to play their appropriate role (see also French and Saatsi, Philosophy of Science, Proceedings of the 2004 PSA Meeting, 78:548–559, 2006) and can be supported by recent case studies illustrating the heterogeneity of scientific practice. My aim in this paper is to further develop this ‘quietist’ view, and to indicate how it offers a fruitful way forward for the philosophy of science. (shrink)

What role have experiments played, and should they play, in physics? How does one come to believe rationally in experimental results? The Neglect of Experiment attempts to provide answers to both of these questions. Professor Franklin's approach combines the detailed study of four episodes in the history of twentieth century physics with an examination of some of the philosophical issues involved. The episodes are the discovery of parity nonconservation in the 1950s; the nondiscovery of parity nonconservation in the 1930s, when (...) the results of experiments indicated, at least in retrospect, the symmetry violation, but the significance of those results was not realized; the discovery and acceptance of CP symmetry; and Millikan's oil-drop experiment. Franklin examines the various roles that experiment plays, including its role in deciding between competing theories, confirming theories, and calling fo new theories. The author argues that one can provide a philosophical justification for these roles. He contends that if experiment plays such important roles, then one must have good reason to believe in experimental results. He then deals with deveral problems concerning such reslults, including the epistemology of experiment, how one comes to believe rationally in experimental results, the question of the influence of theoretical presuppositions on results, and the problem of scientific fruad. This original and important contribution to the study of the philosophy of experimental science is an outgrowth of many years of research. Franklin brings to this work more than a decade of experience as an experimental high-energy physicist, along with his significant contributions to the history and philosophy of science. (shrink)

Visual experiences seem to exhibit phenomenological particularity: when you look at some object, it – that particular object – looks some way to you. But experiences exhibit generality too: when you look at a distinct but qualitatively identical object, things seem the same to you as they did in seeing the first object. Naïve realist accounts of visual experience have often been thought to have a problem with each of these observations. It has been claimed that naïve realist views cannot (...) account for the generality of visual experiences, and that the naïve realist explanation of particularity has unacceptable implications for self- knowledge: the knowledge we have of the character of our own experiences. We argue in this paper that neither claim is correct: naïve realism can explain the generality of experiences, and the naïve realist explanation of particularity raises no problems for our self-knowledge.

Current analytic metaphysics has been claimed to be, at best, out of touch with modern physics, at worst, actually in conflict with the latter The continuum companion to the philosophy of science, Continuum, London, 2011; Ladyman and Ross Every thing must go: metaphysics naturalized, Oxford University Press, Oxford, 2007). While agreeing with some of these claims, it has been suggested that metaphysics may still be of service by providing a kind of ‘toolbox’ of devices that philosophers of science can access (...) in order to help provide an interpretation of theories in fundamental physics Metaphysics in contemporary physics, Rodopi, Amsterdam, 2015). In this context it has been argued that ‘standard’ forms of dispositionalism simply cannot be sustained in the context of modern physics but that certain ‘non-standard’ views may provide the resources to help explicate the sense in which physics may be regarded as ‘modally informed’. Here that suggestion will be further extended in order to consider the implications both with regard to the overall relevance of metaphysics given advances in science and for the prospects of a naturalised metaphysics more generally. In particular, this paper will focus on three concerns: that the particular tools identified are not, in fact, ‘scientifically disinterested’ and thus that the distinction between ‘naturalised’ and ‘non-naturalised’ metaphysics is at best vague or poorly drawn; that the usefulness of such tools depends on their being shaped to fit the relevant physics and thus the latter ‘guts’ metaphysics; that if metaphysics does prove to be useful in this sense then we have no reason to scorn non-naturalised metaphysics to begin with.

How is that when scientists need some piece of mathematics through which to frame their theory, it is there to hand? What has been called 'the unreasonable effectiveness of mathematics' sets a challenge for philosophers. Some have responded to that challenge by arguing that mathematics is essentially anthropocentric in character, whereas others have pointed to the range of structures that mathematics offers. Otavio Bueno and Steven French offer a middle way, which focuses on the moves that have to be (...) made in both the mathematics and the relevant physics in order to bring the two into appropriate relation. This relation can be captured via the inferential conception of the applicability of mathematics, which is formulated in terms of immersion, inference, and interpretation. In particular, the roles of idealisations and of surplus structure in science and mathematics respectively are brought to the fore and captured via an approach to models and theories that emphasize the partiality of the available information: the partial structures approach. The discussion as a whole is grounded in a number of case studies drawn from the history of quantum physics, and extended to contest recent claims that the explanatory role of certain mathematical structures in scientific practice supports a realist attitude towards them. The overall conclusion is that the effectiveness of mathematics does not seem unreasonable at all once close attention is paid to how it is actually applied in practice. (shrink)

This volume is presented in honour of Heinz Post, who founded a distinc tive and distinguished school of philosophy of science at Chelsea College, University of London. The 'Chelsea tradition' in philosophy of science takes the content of science seriously, as exemplified by the papers presented here. The unifying theme of this work is that of 'Correspondence, Invariance and Heuristics', after the title of a classic and seminal paper by Heinz Post, published in 1971, which is reproduced in this volume (...) with the kind permission of the editors and publishers of Studies in History and Philosophy of Science. Described by Paul Feyerabend in Against Method as "brilliant" and " . . . a partial antidote against the view which I try to defend" (1975, p. 61, fn. 17), this paper, peppered with illustrative examples from the history of science, brings to the fore some of Heinz Post's central concerns: the heuristic criteria used by scientists in constructing their theories, the intertheoretic relationships which these criteria reflect and, in particular, the nature of the correspondence that holds between a theory and its predecessors (and its suc cessors). The appearance of this volume more than twenty years later is an indica tion of the fruitfulness of Post's contribution: philosophers of science continue to explore the issues raised in his 1971 paper.

The ontological status of theories themselves has recently re-emerged as a live topic in the philosophy of science. We consider whether a recent approach within the philosophy of art can shed some light on this issue. For many years philosophers of aesthetics have debated a paradox in the (meta)ontology of musical works (e.g. Levinson [1980]). Taken individually, there are good reasons to accept each of the following three propositions: (i) musical works are created; (ii) musical works are abstract objects; (iii) (...) abstract objects cannot be created. However it seems clear that, if one wants to avoid inconsistency, one cannot commit to all three. Following up recent developments courtesy of Cameron ([2008a]), we consider how one might respond to the corresponding set of propositions in the (meta)ontology of scientific theories. 1 Introduction2 Setting up the Problem3 What to Reject? 3.1 Scientific theories are not created? 3.2 Scientific theories are not abstract objects? 3.3 Abstract objects can be created?4 A Fourth Way: Truth-maker Theory5 Objections and Replies 5.1 What are the truth-makers? 5.2 Objections from World 3 5.3 Fictionalism 5.4 Concrete/abstract6 Conclusion.

In lieu of an abstract, here is a brief excerpt of the content:Present Trends of French Philosophical ThoughtAlexandre Koyré and Paola ZambelliThe paper that is published here for the first time was read to the Graduate Faculty of the New School for Social Research by Alexandre Koyré, probably during one of his first trips to the United States as a visiting professor in the fall of 1946 or in the fall of 1950. 1 Given its content and the secondary (...) literature he quoted, the paper seems to go back to the end of 1946, when eight lectures were announced in the Bulletin of the New School, 2 but Koyré probably read only the first of them, deciding to postpone the later ones, because the other subject chosen for his 1946 seminars at the New School (“Les philosophes et la machine”) gained more interest and grew longer. He came back to the New School in 1950 to give some lectures on existentialism [End Page 521] in France, but this time he was the guest of Horace Kallen. 3 But we read in this paper that Koyré had spoken in a series of seminars organized by Albert Salomon. It was determined that Koyré should speak on a broad subject—not only on Sartre’s existentialism, but also on French philosophical trends in general in the first year after the Second World War. His American listeners were obviously interested in hearing about Sartre, Camus, Merleau-Ponty, and the development of the new existentialist school in France.The result was that Koyré prepared a long paper—one that began by mentioning philosophers who had died in the War and the Resistance and concluded with an analysis of Sartre’s ontology and ethics. In the archives of the Centre Koyré in Paris there are three originals of this paper: a longer manuscript which, though earlier in date than the other two, is more complete and provides the basis of my edition, and two shorter typescripts, possibly prepared by the author’s typist with a view to publishing the piece in an American journal. In the first of the two typed versions several sentences, names, and words are missing in the typescript but were inserted into the text by an unknown hand. The second of the typescripts is complete in these points, but its preparation was interrupted for unknown reasons, and the copies (an original and two carbons) bear a final handwritten note: “Le texte s’arrête là.” Happily, the present manuscript version continues to the paper’s original conclusion.Perhaps Koyré, having temporarily mislaid the last pages of the manuscript among his many notes, decided not to publish the paper. 4 The omission from the [End Page 522] body of his published work is regrettable, since this is one of the few papers in which Koyré took a position on contemporary philosophical problems. On the basis of his deep knowledge of Husserl’s and Heidegger’s philosophies, he was able to give a serious interpretation of Sartre. In discussing Sartre, Koyré predominantly used Sartre’s polemical lecture L’exis-tentialisme est un humanisme, read, and published in 1946 as a response to Catholic and Marxist critiques. This was certainly a simpler text than the bulky but more authoritative L’être et le néant. And perhaps it was to avoid taking this latter work in his suitcase that Koyré—as he often did—prepared a selection of fundamental passages for his American trip, copying them first in French and then making what was their first translation into English (published below in an appendix).No doubt, after five years of exile, Koyré wished to familiarize himself with the work of contemporary thinkers, both French and German. Indeed, he had already been doing this, since just before the lecture in New York, Koyré took part in a private debate with Jean Wahl, Maurice Merleau-Ponty, Georges Blin, Maurice de Gandillac, and Gabriel Marcel on the subject of Heidegger’s philosophy. The last two speakers, together with Koyré himself, published their papers from the exchange in a journal and later in a volume introduced by Wahl. In his contribution Koyré emphasized Heidegger’s ideas of “concern [Sorge, souci]” and of “being unto death [zum Tode sein],” writing... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:French Philosophical Thought: Present Trends of French Philosophical Thought *Alexandre Koyré*This is a rather large subject, so you will not be astonished that I shall not treat it in its entirety. French philosophy during the years of war and occupation was pretty active. Though there were some heavy losses: the death of Brunschvicg, posthumous book [...], Héritage de mots, héritage d’idées, 1 a book written when (...) Brunschvicg was in hiding, and a book as “clear and serene as that of Condorcet,” has appeared after the liberation of France; the death of Halbwachs, of Politzer, of Cavaillès, of Lautman shot by the Nazis, of others less well known...; there was the ban on publications by Jewish authors, yet, in spite of this, there has been a surprising number of interesting and even important publications, both during and after the war.It seems that for the elder generation of French philosophers—and that applies not only to philosophers, but to scholars in general—for the generation of men too old to take an active part in the underground move-ment—work, as if nothing happened, has been in the same time a means of escape and a means of resistance. They felt themselves asserting a spiritual tradition that could not be destroyed, and should not be destroyed, and should not be endangered by such contingent “accidents” as Vichy government or even the Gestapo.Thus there have been a new translation of Plato by Robin, books on Plato, on Aristotle, on the medieval (Gilson) and modern philosophy etc., books on philosophy of science, books on sociology, psychology, logic (Méray, Serrus), 2 philosophy of religion, translations of philosophy classics. At the first glance the bibliography of this period (Lavelle, Le Senne, Bachelard, Gilson, etc.) you could have the impression wander in a familiar landscape: yet this would be a completely false impression, because as a matter of fact, this familiar landscape has been completely upturned by the upsurge of existentialism and the revival of Catholic philosophy [End Page 531] (Fessard, 3 De Lubac, Blondel, Nedoncelle, G. Marcel). Under this double impact everything—even the “climate” of philosophy—has changed. Philosophy has become a socially phenomenon.Neither Catholicism nor existentialism are, of course, specifically French intellectual movements. Catholicism is universal ex definitione, and as for existentialism, though French existentialism possesses some specific fea-tures that distinguish it from and even oppose it to the German one, fea-tures that can probably be explained by different national traditions—Descartes, Pascal—it, too, is no more French than it is German. Existen-tialism as such is European by-phenomenon, a definite phase of Western philosophical thought (and European thought, European civilization, at least until the recent—perhaps successful—attempts to destroy it, has been a unity). It originates more than a hundred years ago with Maine de Biran and Kierkegaard, and only has been rediscovered by the twentieth century now. Two thinkers that have been nearly completely neglected by the 19th century—but the 19th century, at least the second part of it, has been a dark age for philosophy—and after the rediscovery or simply the discovery of Kierkegaard in the 20th, it spreads, in Kierkegaard’s wake, from country to country with the usual speed or delay with which ideas travel today. Thus existential philosophy has been, first, developed in Germany in the ‘20s and ‘30s by Heidegger and Jaspers, then—Kierkegaard having been translated into French during the long armistice between the World Wars—in France, some 15 years later. 4 I have heard, by the way, that Kierkegaard has been, or is in the process of being translated into English. So, it is possible that in some 15 or 20 years you will have an existentialism in this country.But to return to France, the rise or upsurge of existentialism has been extraordinarily rapid. It was simultaneous with Husserl’s phenomenolo-gy becoming known in France (Husserl’s last work, Meditations Car-tesiennes, being the text of the lectures he gave in the Sorbonne in 1929, which is now available only in the French translation): from Husserl to...

_The Scope of Morality _ was first published in 1980. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. The scope of morality, Peter A. French contends, is much narrower than many traditional and contemporary works in ethical theory suggest. We trivialize morality if we think it has something to say about everything we do; it touches us all, but not at all times. (...) This essay in philosophical ethics focuses upon the origin, purpose, and function of the various concepts to be found in a more or less mature morality. The author draws a distinction between moral concepts that arise from an individual's wish to live a worthwhile life and those directed towards the development of virtue in the moral community. Moral concepts, in his view, are subjective creations of human beings rather than laws with an objective basis in nature. The ethics of sociobiology, of the lifeboat and spaceship models, and of game theory all come under his critical eye in this useful and progressive work. _The Scope of Morality_, says Hector-Neri Castaneda, "represents a serious effort at discussing the nature of morality, taking into account the most important contributions of recent writers.".

Quassim Cassam offers a conception of ways of knowing which he argues is preferable to rival accounts such as the account we find in Williamson. The correct way to think about ways of knowing matters for philosophers, such as Cassam and Williamson, who want to understand knowledge itself in terms of ways of knowing. So is Cassam right that his conception of ways of knowing is preferable to Williamson's? The discussion to follow is irenic in spirit: I will argue that (...) in fact Cassam and Williamson don't offer competing accounts of the same phenomenon, but consistent accounts of subtly different phenomena. It is then open that ways of knowing in both senses are relevant to elucidating knowledge itself. (shrink)

Some recent work in the philosophy of quantum mechanics has suggested that quantum systems can be thought of as non-separable and therefore non-individual, in some sense, in Bell and E.P.R. type situations. This suggestion is set in the context of previous work regarding the individuality of quantal particles and it is argued that such entities can be considered as individuals if their non-classical statistical correlations are understood in terms of non-supervenient relations holding between them. We conclude that such relations are (...) strongly non-supervenient in Cleland's sense and note a possible connection between this idea and the realist quantum logic programme. (shrink)
