Important to Kuhn's account of scientific change is the observation that when paradigms are in competition with one another, there is a curious breakdown of rational argument and communication between adherents of competing programs. He attributed this to the fact that competing paradigms are incommensurable. The incommensurability thesis centrally involves the claim that there is a deep conceptual gap between competing paradigms in science. In this paper I argue that in one important case of competing paradigms, the Aristotelian explanation of (...) the properties of bodies in terms of matter and form as opposed to the Cartesian mechanist paradigm, where the properties of bodies are explained on the model of machines, there was no such conceptual gap: the notion of a machine was as fully intelligible on the Aristotelian paradigm as it was on the Cartesian. But this does not mean that the debate between the two sides was conducted on purely rational terms. Rational argument breaks down not because of Kuhnian incommensurability, I argue, but because of other cultural factors separating the two camps. (shrink)

As national and state health care policy -making becomes contentious and complex, there is a need for a forum to debate and explore public concerns and values in health care, give voice to local citizens, to facilitate consensus among various stakeholders, and provide feedback and direction to health care institutions and policy makers. This paper explores the role that regional health care ethics committees can play and provides two contrasting examples of Networks involved in facilitation of public input into and (...) the development of health care policies and adoption of state-wide practices.

Van Fraassen's Judy Benjamin problem asks how one ought to update one's credence in A upon receiving evidence of the sort ``A may or may not obtain, but B is k times likelier than C'', where {A,B,C} is a partition. Van Fraassen's solution, in the limiting case of increasing k, recommends a posterior converging to the probability of A conditional on A union B, where P is one's prior probability function. Grove and Halpern, and more recently Douven and Romeijn, (...) have argued that one ought to leave credence in A unchanged, i.e. fixed at P(A). We argue that while the former approach is superior, it brings about a Reflection violation due in part to neglect of a ``regression to the mean'' phenomenon, whereby when C is eliminated by random evidence that leaves A and B alive, the ratio P(A):P(B) ought to drift in the direction of 1:1.

A number of recent studies have called into question the traditional interpretation of Leibniz as an idealist beginning, at the latest, with the composition of the Discourse on Metaphysics (1686). In particular, in a recent book Daniel Garber affirms that between the late 1670s and late 1690s Leibniz maintains a realist doctrine according to which the created world is populated with extended corporeal substances. In trying to prove his thesis, Garber appeals to a document written in 1690 where (...) Leibniz, addressing an objection by Michelangelo Fardella, denies that bodies are composed of souls, declares that souls are substantial forms, and affirms that bodies are composed instead of substances. According to Garber, this shows that Leibniz then believed that bodies were composed, not of simple substances, but of extended substances possessing souls. Here I try to show that, to the contrary, the mentioned document (along with two others closely associated with it) support the traditional interpretation of Leibniz as an idealist in 1690. (shrink)

In this article, we address a major outstanding question of probabilistic Bayesian epistemology: how should a rational Bayesian agent update their beliefs upon learning an indicative conditional? A number of authors have recently contended that this question is fundamentally underdetermined by Bayesian norms, and hence that there is no single update procedure that rational agents are obliged to follow upon learning an indicative conditional. Here we resist this trend and argue that a core set of widely accepted Bayesian norms is (...) sufficient to identify a normatively privileged updating procedure for this kind of learning. Along the way, we justify a privileged formalization of the notion of ‘epistemic conservativity’, offer a new analysis of the Judy Benjamin problem, and emphasize the distinction between interpreting the content of new evidence and updating one’s beliefs on the basis of that content.

Images abound of women throughout the ages engaging in various activities. But why are there so few representations of childbirth in visual art? Feminist artist Judy Chicago once suggested that depictions of women giving birth do not commonly occur in Western culture but can be found in other contexts such as pre-Columbian art or societies previously considered "primitive." Chicago's own exploration of the theme resulted in the creation of The Birth Project (1980-85): an unprecedented series of eighty handcrafted works (...) of art created in a variety of needlework techniques by more than 130 artisans that celebrate the experience of birth and a woman's transformation into motherhood. But why is The Birth Project an aberration from today's norm? What are the reasons that childbirth remains a taboo subject in our visual culture? Why is the birthing experience--so pervasive for women--so infrequently celebrated, even by female artists? (shrink)

It would be good to have a Bayesian decision theory that assesses our decisions and thinking according to everyday standards of rationality — standards that do not require logical omniscience (Garber 1983, Hacking 1967). To that end we develop a “fragmented” decision theory in which a single state of mind is represented by a family of credence functions, each associated with a distinct choice condition (Lewis 1982, Stalnaker 1984). The theory imposes a local coherence assumption guaranteeing that as an (...) agent's attention shifts, successive batches of "obvious" logical information become available to her. A rule of expected utility maximization can then be applied to the decision of what to attend to next during a train of thought. On the resulting theory, rationality requires ordinary agents to be logically competent and to often engage in trains of thought that increase the unification of their states of mind. But rationality does not require ordinary agents to be logically omniscient. (shrink)

This paper examines Descartes' problematic relational theory of motion, especially when viewed within the context of his dynamics, the Cartesian natural laws. The work of various commentators on Cartesian motion is also surveyed, with particular emphasis placed upon the recent important texts of Garber and Des Chene. In contrast to the methodology of most previous interpretations, however, this essay employs a modern "spacetime" approach to the problem. By this means, the role of dynamics in Descartes' theory, which has often (...) been neglected in favor of kinematic factors, is shown to be central to finding a solution to the puzzle of Cartesian motion.

I discuss a contemporary solution to the dynamic problem of old evidence (POE), as proposed by Sprenger. Sprenger’s solution combines the Garber–Jeffrey–Niiniluoto (GJN) approach with Howson’s suggestion of counterfactually removing the old evidence from scientists’ belief systems. I argue that in the dynamic POE, the challenge is to explain how an insight under beliefs in which the old evidence E is known increased the credence of a scientific hypothesis. Therefore, Sprenger’s counterfactual solution, in which E has been artificially removed, (...) does not resolve the problem. I consider several potential responses. (shrink)

In 2019, Christia Mercer has published a paper in which she does a reassessment of the 2015 debate between Garber and Della Rocca on what would be the correct interpretation of Spinoza. Following Mercer, the two philosophers instantiated two main positions regarding the concept and the methodology of doing history of philosophy, namely, contextualism and appropriationism. As Mercer puts it, it is pivoted around the acceptance or rejection of one single principle, i.e. the "Getting Things right Constraint" (GTRC) which (...) can be rendered as the clause that forbids the attribution of claims or ideas to historical figures without concern for whether or not they are ones the figures would recognize as their own. However, rather than be an undoubtful principle, it conceals a great number of tough questions about the very meaning of what names the “Austrian approach” to the history of philosophy, this paper aims to unfold some aspects of Brentano’s “philosophy of history of philosophy” to look for his contributions to a problem that was already present at the origins of contemporary philosophy.

This highly multidisciplinary collection discusses an increasingly important topic among scholars in science and technology studies: objectivity in science. It features eleven essays on scientific objectivity from a variety of perspectives, including philosophy of science, history of science, and feminist philosophy. Topics addressed in the book include the nature and value of scientific objectivity, the history of objectivity, and objectivity in scientific journals and communities. Taken individually, the essays supply new methodological tools for theorizing what is valuable in the pursuit (...) of objective knowledge and for investigating its history. The essays offer many starting points, while suggesting new avenues of research. Taken collectively, the essays exemplify the very virtues of objectivity that they theorize—in reading them together, the reader can sense various anxieties about the dangerously subjective in our age and locate commonalities of concern as well as differences of approach. As a result, the volume offers an expansive vision of a research community seeking a communal understanding of its own methods and its own epistemic anxieties, struggling to enunciate the key problems of knowledge of our time and offer insight into how to overcome them. -/- (Contributors: Alex Csiszar, Scott Edgar, Peter Galison, Ian Hacking, Sandra Harding, Moira Howes, Paolo Savoia, Judy Segal, Joan Steigerwald, and Alison Wylie).

Leibnizian metaphysics is traditionally held to be idealistic. It means that reality is composed of soul-like substances whereas material bodies are mere phenomena. The traditional interpretation presupposes that Leibniz’s view has not changed during the mature period (from 1683 onward). Some commentators have recently challenged this view. They claim that either Leibniz (despite inconsistency) was both a realist and an idealist (Hartz), or changed his view on the nature of substance (Garber). The aim is to defend the traditional interpretation (...) and to reply to the arguments by realist commentators. (shrink)

Spinoza’s conatus doctrine, the main proposition of which claims, “[e]ach thing, to the extent it is in itself, strives [conatur] to persevere in its being” (E3p6), has been the subject of growing interest. This is understandable, for Spinoza’s psychology and ethics are based on this doctrine. In my paper I shall examine the way Spinoza argues for E3p6 in its demonstration which runs as follows: "For singular things are modes by which God’s attributes are expressed in a certain and determinate (...) way (by 1p25c), i.e. (by 1p34), things that express, in a certain and determinate way, God’s power, by which God is and acts. And no thing has anything in itself by which it can be destroyed, or which takes its existence away (by p4). On the contrary, it is opposed to everything which can take its existence away (by p5). Therefore, to the extent it can, and is in itself, it strives to persevere in its being." This argument has been severely criticized for being defective in many ways. E3p6d contains four items, E1p25c, 1p34, 3p4, and 3p5. Most often, only the two last mentioned are regarded as doing any real work in the demonstration. However, I shall argue that having a proper grasp of Spinoza’s concept of power enables us see that the demonstration’s beginning, built on E1p25c and 1p34, brings forth a certain dynamic framework in which finite things are centers of causal power, capable of producing effects in virtue of their essences. My examination of this framework shows the beginning of the demonstration to be irreplaceable: in the end, conatus is one form of power, and E1p25c and 1p34 not only bring the notion of power into play, but also inform us on how finite things’ power should be understood in the monistic system. So, I disagree with such commentators as Jonathan Bennett, Edwin Curley, Daniel Garber, Michael Della Rocca, and Richard Manning, who see Spinoza as trying to derive the conatus doctrine from E3p4 and 3p5 alone; and I agree with Alexandre Matheron, Henry Allison, and Martin Lin, who stress the importance of E1p25c and 1p34. -/- However, this still leaves us the task of reconstructing the whole derivation and showing how its various ingredients fit together. If E1p25c and 1p34 are so important, could E3p6 not be derived from them alone, as Martin Lin has argued? In other words, why are E3p4 and 3p5 needed at all? To answer these questions I shall provide an interpretation of E3p6d that explains how the argument is supposed to work. E1p25c and 1p34 say that finite things are, in essence, dynamic causers, which, in case of opposition, truly resist opposing factors with their power and do not simply cease their causal activities whenever facing obstacles; in other words, they strive against any opposition. However, this is not enough to guarantee that they could not act self-destructively or restrain their own power, which would make them incapable of self-preservation. But this would go against E3p4, “No thing can be destroyed except through an external cause,” and Spinoza uses it to claim, “no thing has anything in itself by which it can be destroyed, or which takes its existence away.” So all this allows Spinoza to hold that finite things are consistent causers, that is, entities endowed with power and, insofar they cause effects solely in virtue of their essence, they never use their power self-destructively. The significance and role of the final item in the demonstration, E3p5 (“Things are of a contrary nature, i.e., cannot be in the same subject, insofar as one can destroy the other”), still needs to be determined. Indeed, considering its content and the way it is used in the demonstration, it seems to be a surprisingly decisive ingredient in the argument. Namely, what “each thing, to the extent it is in itself,” that is, insofar as any thing is considered disregarding everything external to it, strives to preserve, is its being (esse), not simply its present state. This together with E3p5’s view of subjecthood – which I shall explicate in my paper – suggests that we should rethink what kind of “being” or “existence” is meant in E3p6. Indeed, for Spinoza, each subject has a definable essence from which, as far as the subject in question is in itself, certain properties or effects necessarily follow; consequently a subject’s full being involves not only instantiating a certain essence, but also those properties inferable from the essence-expressing definition. Thus, E3p5 is meant to bring forward that things are not merely non-self-destroyers but subjects from whose definitions properties follow; and as Spinoza thinks to have shown (by E1p25c and 1p34) that finite modifications are entities endowed with power, any subject has true power to produce the properties or effects derivable from its definition, which, Spinoza claims, implies opposing everything harmful. In other words, things exercise power as their definition states, i.e. according to their definitions, and thus bringing in the idea of things as expressers of power enables Spinoza to convert logical oppositions (of E3p5) into real ones (of E3p6). To summarize, Spinoza reasons that each true finite thing is, in itself, an expresser of power (E1p25c, 1p34) that never acts self-destructively (E3p4) but instead strives to drive itself through opponents to produce effects as they follow from the definition of the thing in question (E1p25c, 1p34, and 3p5). Therefore, “each thing, to the extent it is in itself, strives to persevere in its being.” The demonstration of E3p6 has its roots deep in Spinoza’s ontology, and since its concept of power is supposed to provide the metaphysical grounding for real opposition, the importance of E1p25c and 1p34 should not be underestimated just because Spinoza – as often happens – puts his point exceedingly briefly. Moreover, the derivation is basically valid and contains no superfluous elements. Finally, all this tells us something decisive about the meaning of Spinoza’s doctrine: according to it, things are active causers whose “power to exist and act” has conatus character in temporality, amounting not only to striving to prolong the duration of one’s actualization but also to striving to be as active or autonomous as possible, that is, to attain a state determined by the striving subject’s essence alone.

Complex constraints like conditionals ('If A, then B') and probabilistic constraints ('The probability that A is p') pose problems for Bayesian theories of learning. Since these propositions do not express constraints on outcomes, agents cannot simply conditionalize on the new information. Furthermore, a natural extension of conditionalization, relative information minimization, leads to many counterintuitive predictions, evidenced by the sundowners problem and the Judy Benjamin problem. Building on the notion of a `paradigm shift' and empirical research in psychology and economics, (...) I argue that the model of hypothesis testing can explain how people learn complex, theory-laden propositions like conditionals and probability constraints. Theories are formalized as probability distributions over a set of possible outcomes and theory change is triggered by a constraint which is incompatible with the initial theory. This leads agents to consult a higher order probability function, or a 'prior over priors,' to choose the most likely alternative theory which satisfies the constraint. The hypothesis testing model is applied to three examples: learning a simple probabilistic constraint involving coin bias, the sundowners problem for conditional learning, and the Judy Benjamin problem for learning conditional probability constraints.

This essay explores two of the more neglected hypotheses that comprise, or supplement, Descartes’ relationalist doctrine of bodily motion. These criteria are of great importance, for they would appear to challenge Descartes’ principal judgment that motion is a purely reciprocal change of a body’s contiguous neighborhood. After critiquing the work of the few commentators who have previously examined these forgotten hypotheses, mainly, D. Garber and M. Gueroult, the overall strengths and weaknesses of Descartes’ supplementary criteria will be assessed. Overall, (...) despite their ingenuity, it will be demonstrated that Descartes’ criteria cannot rescue his brand of natural laws from the inherent limitations of his strong relational account of motion.

Benjamin Libet's celebrated experiments concerning freedom elicited numerous attempts of _philosophical_ repudiation. Ten years ago, however, Judy Trevena and Jeff Miller published a _technical_ objection; they claim to have detected a,,smearing artifact" in Libet's calculations. This rests on a misunderstanding of Libet's methodology. In my reconstruction of Libet's argument, he draws an abductive inference to the best explanation. Now, Trevena's and Miller's objection does indeed lead to alternative explanations of Libet's measurements. These alternatives are _ad hoc_ and extremely improbable. (...) They constitute worse explanations than the explanation offered by Libet. _German_ Benjamin Libets bahnbrechende Experimente zur Willensfreiheit aus den Achtziger Jahren des vorigen Jahrhunderts gehören längst zu den Klassikern der Experimentalkunst. Aus _philosophischer_ Perspektive sind sie oft kritisiert worden; unabhängig davon ist zu Beginn des neuen Jahrtausends ein _technischer_ Einwand gegen Libet prominent geworden, der von Freiheitsfreunden gerne zitiert wird. Er geht auf Judy Trevena und Jeff Miller zurück und besteht in dem Vorwurf, dass Libet mit seiner Berechnung der _gemittelten_ Bereitschaftspotential-Kurven die wahren Verhältnisse verschmiere und dabei aus mathematischen Gründen den Anstiegs-Zeitpunkt des Bereitschaftspotentials künstlich nach vorne verschiebe – das ist der Vorwurf des sog. Verschmierungsartefakts. Ich zeige, dass der Vorwurf nicht sticht. Er beruht auf einem Missverständnis der Schlussmethode Libets. Laut meiner wissenschaftstheoretischen Rekonstruktion zieht Libet weder deduktive noch induktive Schlüsse aus seinen Einzelbeobachtungen; er schließt abduktiv, d.h. er schließt auf die beste Erklärung seiner Einzelbeobachtungen. Wie eine genaue arithmetische Analyse zeigt, bieten die Alternativ-Erklärungen, unter denen sich das Verschmierungsartefakt bewahrheiten würde, schlechtere Erklärungen als Libets Erklärung – sie sind an den Haaren herbeigezogen und extrem unwahrscheinlich.

This is basically a paper about artistic evaluation and how multiple interpretations can give rise to inconsistent and conflicting meanings. Images like Joel-Peter Witkin’s First Casting for Milo (2004) challenge the viewer to look closely, understand the formal properties at work, and then extract a meaning that ultimately asks, Is the model exploited or empowered? Is Karen Duffy, pictured here, vulnerable and “enfreaked” or is she potentially subversive, transgressive, and perhaps self-empowered? I will offer an argument in agreement with artist/author/ (...) performer Ann Millett-Gallant that favors the latter interpretation, but will augment and complicate the issue by also introducing a pointed question or two taken from a recent analysis by Cynthia Freeland on objectification. I judge the works by photographer Joel-Peter Witkin to be representations of disabled persons who are empowered through agency and pride, but I also worry about the risk of multiple, conflicting interpretations on the part of viewers who do not, or cannot, entertain such enlightened readings. Like second wave feminist views about pornography that depicted women in demeaning ways, or feminist critiques of Judy Chicago’s The Dinner Party , Witkin’s photos can be judged as potentially offensive. But they are also objects of beauty—both in terms of aesthetic properties (they are magnificent studies in black and white, shadows, the human body, with many classical references) and because of the feeling of beauty and pride felt by the posers, who become performers of their own beauty and pride. I argue that beauty trumps offensiveness. Pride wins. But I’m not sure that everyone will agree. (shrink)

Arthur C. Danto, philosopher and art critic for The Nation from 1984-2009, offered interpretations of artworks by a wide array of artists, including Eva Hesse, Judy Chicago, and Cindy Sherman, whose "disturbatory" works were either ignored or denounced by mainstream critics at the time. Danto's championing of feminist art was deliberate and delightful; he openly endorsed the Guerilla Girls! His feminist art critical writings ultimately shaped the early development of what has come to be known as "feminist aesthetics" particularly (...) his focus on defiant artworks by female artists who sought to reclaim agency and expression of the female body. He revived interest in the neglected topic of beauty while simultaneously advancing radical political goals within the artworld. His call to arms urged art viewers to experience the new--what he often called "art on the edge and over"--wherein, "The experience of art becomes a moral adventure rather than merely an aesthetic interlude" (in Art on the Edge and Over: Searching for Art's Meaning in Contemporary Society 1970s-1990s, 1996).

This anthology is about the signal change in Leibniz’s metaphysics with his explicit adoption of substantial forms in 1678-79. This change can either be seen as a moment of discontinuity with his metaphysics of maturity or as a moment of continuity, such as a passage to the metaphysics from his last years. Between the end of his sejour at Paris and the first part of the Hanover period, Leibniz reformed his dynamics and began to use the theory of corporeal substance. (...) This book explores a very important part of the philosophical work of the young Leibniz. Expertise from around the globe is collated here, including Daniel Garber’s work based on the recent publication of Leibniz's correspondence from the late 1690s, examining how the theory of monads developed during these crucial years. Richard Arthur argues that the introduction of substantial forms, reinterpreted as enduring primitive forces of action in each corporeal substance, allows Leibniz to found the reality of the phenomena of motion in force and thus avoid reducing motion to a mere appearance. Amongst other themes covered in this book, Pauline Phemister’s paper investigates Leibniz’s views on animals and plants, highlighting changes, modifications and elaborations over time of Leibniz’s views and supporting arguments and paying particular attention to his claim that the future is already contained in the seeds of living things. The editor, Adrian Nita, contributes a paper on the continuity or discontinuity of Leibniz’s work on the question of the unity and identity of substance from the perspective of the relation with soul and mind.

This paper is an engagement with Equality by John Baker, Kathleen Lynch, Judy Walsh and Sara Cantillon. It identifies a dilemma for educational egalitarians, which arises within their theory of equality, arguing that sometimes there may be a conflict between advancing equality of opportunity and providing equality of respect and recognition, and equality of love care and solidarity. It argues that the latter values may have more weight in deciding what to do than traditional educational egalitarians have usually thought.

The immediate occasion for this special issue was Christia Mercer’s influential paper “The Contextualist Revolution in Early Modern Philosophy”. In her paper, Mercer clearly demarcates two methodologies of the history of early modern philosophy. She argues that there has been a silent contextualist revolution in the past decades, and the reconstructivist methodology has been abandoned. One can easily get the impression that ‘reconstructivist’ has become a pejorative label that everyone outright rejects. Mercer’s examples of reconstructivist historians of philosophy are deceased (...) (P. F. Strawson, Margaret J. Osler, Richard Watson, and Bernard Williams), anonymous (the fans of philosopher* mentioned by Lisa Downing), or authors whose more recent work followed a contextualist methodology (Jonathan Bennett). The reconstructivist camp seems to have turned into a shadowy group, largely extinct by now, not unlike the Death Eaters in the fictional universe of Harry Potter. There are some figures who previously belonged to this group, but they have since reformed their ways – or so it seems. Sometimes it is rumoured that certain people may still have secret allegiance to it, but no one dares to fly its banner openly. We decided to create this special issue because we believe that reconstructivist methodology does not deserve this shadowy existence. (shrink)
