This series of images forms part of the ongoing project Soft Ground, Hard Light, which speculates on a multiscalar spatial ontology of photography emanating from the Arditurri silver mine complex in the Basque Country. Evoking the mountainous massif around Arditurri where silver ore and galena have been extracted since Roman presence in the area, the depicted topographies are, in fact, data transcriptions from atomic force microscopy (AFM) probing the analogue film stock of an early 1930s experiment in 3D (...) cinema, Cine en Relieve, by the Basque cinematographer Teófilo Mingueza. In contrast to optical or electron microscopy, AFM uses a scanning probe to physically touch the specimen, recording its surface undulations at the atomic scale of a nanometre, or a billionth of a metre. As a haptic operation based on direct contact between instrument and sample, between apparatus and referent, AFM is literally a contact print, a ‘blind’ scan that senses not the visual content of the recorded image but ‘feels’ its underlying material substrate of silver nanoparticles within the 35 mm film emulsion. The resulting image assemblies visualize a topography resulting from the intra-action between the silver nanoparticles and the scanning probe as much as its transcription through the particular parameters afforded by the AFM analysis software. Hard Light, Soft Ground was initiated during an artist’s residency at Tabakalera Centre for Contemporary Culture, Donostia-San Sebastián, and is currently in production as part of the wider research project Esper Syndrome: Archaeotopologies of the Image at the Royal College of Art, funded by the AHRC through the London Arts & Humanities Partnership.

This paper discusses the operations meant to act on situations of ontological uncertainties for chemicals. Using examples related to substances developed as part of nanotechnology programs, it analyses technical and social instruments meant to define the existence of these substances, as « new » or « existing » chemicals. Carbon nanotubes developed by a French company offer an illustration of containment, while the legal disputes about nano silver in the U.S. display oppositions about whether or not these compounds are (...) equivalent to colloïdal silver. The operations meant to deal with the ontological uncertainty of these substances define categories and craft political organizations. As such, they suggest developing an analytical approach able to jointly examine the ontologies of material objects and the forms of political ordering. (shrink)

ObjectiveThe use of nanotechnologies is important to reduce environmental health problems in Iran, so the present study was conducted to determine the effectiveness of nanotechnologies in environmental health. This is a cross-sectional descriptive study for 11-year periods (2008–2018) on all articles published in three specialized journals of environmental health with emphasis on the use of nanotechnologies in various fields of environmental health (water, air, sewage, waste, food, radiation, etc).ResultsIn this study, 774 articles related to 114 issues of 3 specialized environmental (...) health journals were reviewed. A review of 774 articles showed that 80 articles (10.3%) were published in the field of nanotechnologies. Out of 80 articles published in the field of nanotechnology, 66 articles (82.5%) were published on the subject of water, 9 articles (11.3%) on wastewater and 5 articles (6.2%) on air pollution. Subject review of articles showed that articles using carbon nanotubes to remove natural organic pollutants, surfactants, hydroxybenzenes, phenol, dimethyl phthalates, use of titanium dioxide nanoparticles, iron-magnesium nanoparticles for wastewater treatment, Silver nanoparticles were used to remove air pollution. The results showed that published articles on nanotechnology in the field of environmental health were few. (shrink)

Nanotechnology thrives in the realm of the virtual. Throughout its history, the field has been shaped by futuristic visions of technological revolution, hyperbolic promises of scientific convergence at the molecular scale, and science fiction stories of the world rebuilt atom by atom. Even today, amid the welter of innovative nanomaterials that increasingly appear in everyday consumer products—the nanoparticles enhancing our sunscreens, the carbon nanotubes strengthening our tennis rackets, the antimicrobial nano-silver lining our socks, the nanofilms protecting our wrinkle-free (...) trousers—the public rhetoric of nanotechnology constantly reminds us that such precision-engineered materials merely represent a trace or a premonition of the amazing future still to come...

In this article, ethylene glycol + waterbased Maxwell nanofluid with radiation and Soret effects within two parallel plates has been investigated. The problem is formulated in the form of partial differential equations. The dimensionless governing equations for concentration, energy, and momentum are generalized by the fractional molecular diffusion, thermal flux, and shear stress defined by the Caputo–Fabrizio time fractional derivatives. The solutions of the problems are obtained via Laplace inversion numerical algorithm, namely, Stehfest’s. Nanoparticles of silver are suspended (...) in a mixture of EG + water to have a nanofluid. It is observed that the thermal conductivity of fluid is enhanced by increasing the values of time and volume fraction. The temperature and velocity of water-silver nanofluid are higher than those of ethylene glycol + water -silver nanofluid. The results are discussed at 2% of volume fraction. The results justified the thermo-physical characteristics of base fluids and nanoparticles shown in the tables. The effects of major physical parameters are illustrated graphically and discussed in detail. (shrink)

In his essay, “Negative and Positive Positivism,” Jules L. Coleman extends in two important ways the Legal Positivism of H. L. A. Hart. First, he shows that the “separability thesis”—the claim that no necessary or constitutive relationship exists between law and morality—to which Positivists are wedded does not entail the view, attributed by Ronald Dworkin to Legal Positivists, that law consists in “hard facts.” Instead, the separability thesis requires only the possibility of deciding the truth of propositions of law. This (...) weaker requirement can be met by rules of recognition that are semantically adequate but that fail to set out tests by means of which the legal status of rules and norms may be verified. Second, Coleman argues that one can subscribe to the separability thesis and still maintain that judges may have a legal duty to couch decisions in moral terms whenever the “content or proper formulation of [a] rule of recognition” is in dispute. Such a legal duty may exist in virtue of a convergent practice “among judges of resolving the controversy in a particular way”. (shrink)

This paper argues that Wittgenstein opposed theories of meaning, and did so for good reasons. Theories of meaning, in the sense discussed here, are attempts to explain what makes it the case that certain sounds, shapes, or movements are meaningful linguistic expressions. It is widely believed that Wittgenstein made fundamental contributions to this explanatory project. I argue, by contrast, that in both his early and later works, Wittgenstein endorsed a disjunctivist conception of language which rejects the assumption underlying the question (...) that such theories seek to answer—namely, the assumption that the notion of a meaningful linguistic expression admits of non-circular analysis. Moreover, I give two arguments in favor of the view I ascribe to Wittgenstein: one based on later Wittgenstein's discussion of meaning skepticism and one based on considerations concerning the identity of linguistic expressions.

Most business ethicists maintain that corporate actors are subject to a variety of moral obligations. However, there is a persistent and underappreciated concern that the competitive pressures of the market somehow provide corporate actors with a far-reaching excuse from meeting these obligations. Here, we assess this concern. Blending resources from the history of philosophy and strategic management, we demonstrate the assumptions required for and limits of this excuse. Applying the idea of ‘the state of nature’ from Thomas Hobbes, we suggest (...) that corporate actors would be excused from duties if complying with them threatened their vital interests. We show how this excuse is not available for most individuals within firms; instead, it is an excuse perhaps available to firms themselves, but only given substantive assumptions about corporate personhood. For those willing to make these assumptions, we apply the competitive advantage construct to delimit the scope of this excuse. We suggest that firms are excused from fulfilling an obligation when complying leads to a competitive disadvantage, as this imperils the firm’s vital interests. After revealing why this excuse does not generalize, we conclude by considering when we should reform the market to avoid the legitimacy of this excuse. (shrink)

Originally published 1974. Thousands of elementary schools for the children of the poor were founded during the nineteenth century, yet there is scarcely a published history of a single one of them. This volume is precisely such a history and the authors trace its story against the background of local and national change in education and society. On the basis of a unique collection of records the authors have pieced together a picture of the social composition of the school, its (...) curriculum and teaching methods, and its administration and finance. They relate the history of the school to that of London and the church, to that of educational authorities and educational policy. (shrink)

Groups behave in a variety of ways. To show that this behavior amounts to action, it would be best to fit it into a general account of action. However, nearly every account from the philosophy of action requires the agent to have mental states such as beliefs, desires, and intentions. Unfortunately, theorists are divided over whether groups can instantiate these states—typically depending on whether or not they are willing to accept functionalism about the mind. But we can avoid this debate. (...) I show how a more general view of action captures what is central to action without mentioning mental states, and I argue that a group’s members can fulfill the role in group action that mental states play in our actions. Group behavior is explicable in terms of reasons, regardless of whether the group itself cognizes those reasons. After discussing the kind of reasons at issue and arguing that groups can act in light of them without minds, I assess how this account bears on the question of group responsibility. (shrink)

Nonreductive naturalism holds that we can preserve the (scientifically valued) metaphysical truth of physicalism while averting the methodological mistakes of reductionism. Acceptable scientificexplanation need not (in some cases cannot and in many cases, should not) be formulated in the language of physical science. Persuasive arguments about the properties of phenomenal consciousnesspurport to show that physicalism is false, namely that phenomenal experience is a nonphysical fact. I examine two recent, comprehensive efforts to naturalize phenomenal consciousness and argue thatnonreductive naturalism yields a (...) dilemma of reductionism or panpsychism. (shrink)

Whereas many philosophers take backwards causation to be impossible, the few who maintain its possibility either take it to be absent from the actual world or else confined to theoretical physics. Here, however, I argue that backwards causation is not only actual, but common, though occurring in the context of our social institutions. After juxtaposing my cases with a few others in the literature and arguing that we should take seriously the reality of causal cases in these contexts, I consider (...) several objections. These objections involve whether the cases should be reinterpreted, whether they are properly within the institution, whether they involve necessitation or else Cambridge changes, whether and how they involve changing the past, and whether this should call us to question institutional reality. I end by suggesting that it is a virtue of our institutions that they allow backwards causation, that this is a kind of technology that they are often built to incorporate. (shrink)

Agent causation presupposes that actions are behaviors under the causal control of the agent’s mental states, its beliefs and desires. Here the idea of conscious causation in causal explanations of actions is examined, specifically, actions said to be the result of conscious efforts. Causal–functionalist theories of consciousness purport to be naturalistic accounts of the causal efficacy of consciousness. Flanagan argues that his causal–functionalist theory of consciousness satisfies naturalistic constraints on causation and that his causal efficacy thesis is compatible with results (...) of Libet’s experiments on conscious causation. First, the notions of conscious effort and conscious causation are analyzed with respect to the project of naturalizing the mind, that is, the attempt to assimilate folk-psychological explanation to the causal model of explanation in the natural sciences. It is argued that a serious obstacle for any naturalist program is that mental states are individuated by their semantic content, not the mechanistic, physical properties of their neural state instantiations. In particular, it is argued that explanation by reference to mental state content yields not a causal but an interpretive or rationalizing account of action in which the question of causal efficacy is irrelevant. Then, Flanagan’s causal–functionalist theory of consciousness is critically assessed; specifically his interpretations of Libet’s negative experimental results on the causal efficacy of consciousness are diagnosed and disputed. It is contended that Flanagan misinterprets the results of Libet’s consciousness experiments and that his functionalist concept of consciousness fails to yield an adequate explanation of the alleged causal efficacy of consciousness. Finally, his thesis is countered with other experimental results that appear to favor an epiphenomenalist view over the causal efficacy account of consciousness. (shrink)

To some students with disabilities who take philosophy classes, and even to some professors with disabilities who teach philosophy, the discipline is not welcoming. Philosophical theory traditionally recognizes so-called normal people and common modes of functioning but seems to ignore or disparage biologically anomalous individuals. The adequacy of our epistemological and ethical philosophies is a pressing reason for us to acknowledge disability in philosophical theorizing. And there are equally pressing reasons to acknowledge that students with various kinds of disabilities are (...) members of our classes. In this special issue of Teaching Philosophy the authors reflect on how disability is engaged with in their philosophy classrooms for and by their students, and in the philosophy they teach.

Respondeat superior is a legal doctrine conferring liability from one party onto another because the latter stands in some relationship of authority over the former. Though originally a doctrine of tort law, for the past century it has been used within the criminal law, especially to the end of securing criminal liability for corporations. Here, I argue that on at least one prominent conception of criminal responsibility, we are not justified in using this doctrine in this way. Firms are not (...) answerable for the crimes committed by their employees, because firms cannot answer as to why the crime was committed; they lack the authority to offer the employee’s reasons for action. Though this rules out respondeat superior as a general principle, I show contexts in which vicarious liability is still appropriate in the criminal law, and I respond to a number of other concerns raised by this picture.

Complex systems are pervasive in the world around us. Making sense of a complex system should require that a person construct a network of concepts and principles about some domain that represents key (often dynamic) phenomena and their interrelationships. This raises the question of how expert understanding of complex systems differs from novice understanding. In this study we examined individuals' representations of an aquatic system from the perspective of structural (elements of a system), behavioral (mechanisms), and functional aspects of a (...) system. Structure–Behavior–Function (SBF) theory was used as a framework for analysis. The study included participants from middle school children to preservice teachers to aquarium experts. Individual interviews were conducted to elicit participants' mental models of aquaria. Their verbal responses and pictorial representations were analyzed using an SBF‐based coding scheme. The results indicated that representations ranged from focusing on structures with minimal understanding of behaviors and functions to representations that included behaviors and functions. Novices' representations focused on perceptually available, static components of the system, whereas experts integrated structural, functional, and behavioral elements. This study suggests that the SBF framework can be one useful formalism for understanding complex systems. (shrink)

Although Maimonides is now known as one of the greatest Jewish theologians and philosophers of the middle ages, his writings were denounced from the outset - first in the East then in the West. In fact, by the mid-1230's the so-called Maimonidean Controversy that had begun within the Jewish community had spread to encompass much of the Christian scholarly world as well. Daniel Silver's Maimonidean Criticism constitutes a landmark in the historiography of Maimonideanism in general and of the controversy (...) of the 1230s in particular. Brill has thus brought this important book back into print for students wishing an introduction to this debate. (shrink)

It is almost universally accepted that the Frege–Geach Point is necessary for explaining the inferential relations and compositional structure of truth-functionally complex propositions. I argue that this claim rests on a disputable view of propositional structure, which models truth-functionally complex propositions on atomic propositions. I propose an alternative view of propositional structure, based on a certain notion of simulation, which accounts for the relevant phenomena without accepting the Frege–Geach Point. The main contention is that truth-functionally complex propositions do not include (...) as their parts truth-evaluable propositions, but their simulations, which are neither forceful nor truth-evaluable. The view makes room for the idea that there is no such thing as the forceless expression of propositional contents and is attractive because it provides the resources for avoiding a fundamental problem generated by the Frege–Geach Point concerning the relation between forceless and forceful expressions of propositional contents. I further argue that the acceptance of the Frege–Geach Point mars Peter Hanks’ and François Recanati’s recent attempts to resist the widespread idea that assertoric force is extrinsic to the expression of propositional contents. Rejecting this idea, I maintain, requires a deeper break with the tradition than Hanks and Recanati have allowed for. (shrink)

Frege appears to hold both that thoughts are internally articulated, in a way that mirrors the semantic articulation of the sentences that express them, and that the same thought can be analyzed in different ways, none of which has to be more fundamental than the others. Commentators have often taken these theses to be mutually incompatible and have tended to polarize into two camps, each of which attributes to Frege one of the theses, but maintains that he is only apparently (...) committed to the other. This paper argues that there are good exegetical and philosophical reasons for reconciling the two theses; that this reconciliation can be achieved by rejecting an assumption shared by the two opposite camps of the exegetical debate, i.e., the assumption that essential articulatedness implies unique articulation; and finally, that this crucial assumption can be resisted by appreciating Frege’s anti-atomistic and ‘organic’ conception of the internal complexity of thoughts.

The standard case of weakness of will involves a strong temptation leading us to reconsider or act against our judgments. Here, however, I consider cases of what I call ‘habitual weakness', where we resolve to do one thing yet do another not to satisfy any grand desire, but out of habit. After giving several examples, I suggest that habitual weakness has been under-discussed in the literature and explore why. These cases are worth highlighting for their ubiquity, and I show three (...) further advantages of appreciating habitual weakness as a kind of weakness: It challenges purportedly necessary conditions on akrasia, it side-steps outstanding skeptical concerns, and it provides a new model for considering the weak-willed behavior of group agents. I conclude by arguing that cases of habitual weakness are genuine cases of akrasia and weakness of will. Rather than lacking strength of will, habitual weakness involves lacking diligence, vigilance, or fortitude. (shrink)

Emergence is typically discussed in the context of mental properties or the properties of the natural sciences, and accounts of emergence within these contexts tend to look a certain way. The emergent property is taken to emerge instantaneously out of, or to be proximately caused by, complex interaction of colocated entities. Here, however, I focus on the properties instantiated by the elements of certain systems discussed in social ontology, such as being a five-dollar bill or a pawn-movement, and I suggest (...) that these properties emerge in a distinctive way. They emerge in part because of a system that is far beyond and typically before the object that instantiates them. I characterize how emergence occurs in these cases, juxtaposing it with how emergence is typically discussed. I then consider whether their emergence is best framed as weak or strong as these notions are characterized in the literature, and I reveal what debates are central to answering this question. Though I will not resolve these debates, I do show a collection of views that would vindicate these properties as strongly emergent and downwardly causing. (shrink)

The ‘limits of markets’ debate broadly concerns the question of when it is (im)permissible to have a market in some good. Markets can be of tremendous benefit to society, but many have felt that certain goods should not be for sale (e.g., sex, kidneys, bombs). Their sale is argued to be corrupting, exploitative, or to express a form of disrespect. InMarkets without Limits, Jason Brennan and Peter Jaworski have recently argued to the contrary: For any good, as long as it (...) is permissible to give it for free, then it is permissible to give it for money. Their thesis has led to a number of engaging objections, and I leverage recent work on the nature of feasibility within political philosophy to offer a new challenge.I argue that feasibility offers a constraint on which markets can be permissibly implemented. Though it may be possible to create a morally acceptable version of an otherwise repugnant market, some of these markets may be infeasible, and so we are not permitted to implement them. After laying out this challenge, I consider several replies. They concern the relevance of feasibility, and whether any markets really are infeasible. This provides an opportunity to explore the dangers of pursuing the infeasible and with markets generally. I conclude by considering what might lead us to pursue these markets despite their infeasibility, or how knowledge of infeasibility may prove useful regardless. (shrink)

A pesar de toda la plausibilidad del externalismo en relación al significado lingüístico, la cuestión crucial es la de cómo el externalismo se enfrenes a nuestras intuiciones cartesianas mas profundas sobre el contenido de la experiencia consciente. La tradición cartesiana respecto a la experiencia consciente parece invulnerable al análisis externalista porque las propiedades fenomenológicas de los estados conscientes sitúan el lugar de la experiencia enteramente dentro del sujeto de la misma, y la bacen exclusivamente dependiente de él. Un externalismo consecuente (...) y consistente acerca de la mente requiere un argumento sobre la experiencia consciente paralelo al desarrollado sobre el significado. En este trabajo, se examina críticamente un argumento elaborado por Martin Davies a favor de la compatibilidad del externalismo con la idea de la existencia de un contenido no-conceptual en la experiencia perceptiva consciente, el contenido perceptual de los estados mentales en cuanto son experimentados por criaturas conscientes.

We concur that basic research on the use of CNS grafts is needed. Two important model systems for functional studies of grafts are ignored by Stein & Glasier. In the first, reproductive function is restored in hypogonadal mice by transplantation of GnRH-synthesizing neurons. In the second, circadian rhythmicity is restored by transplantation of the suprachiasmatic nucleus.

In Philosophy as Frustration: Happiness Found and Feigned from Greek Antiquity to Present Bruce Silver argues that traditional philosophical views of happiness, as well as recent psychological theories of happiness, are at odds with themselves and with important accounts of a truly happy life.

Much has been written about what corporations owe society and whether it is appropriate to hold them responsible. In contrast, little has been written about whether anything is owed to corporations apart from what is owed to their members. And when this question has been addressed, the answer has always been that corporations are not worthy of any distinct moral consideration. This is even claimed by proponents of corporate agency. In this paper, I argue that proponents of corporate agency should (...) recognize corporations as worthy of moral consideration. Though particular views of moral status are often taken for granted in the literature, corporations can satisfy many views of moral status given the capacities often ascribed to them. They can even meet the conditions of the views assumed. I conclude by suggesting that recognizing the moral status of corporations may not be as drastic or harmful as we might imagine. (shrink)

Proponents of corporate moral responsibility take certain corporations to be capable of being responsible in ways that do not reduce to the responsibility of their members. If correct, one follow-up question concerns what leads corporations to fail to meet their obligations. We often fail morally when we know what we should do and yet fail to do it, perhaps out of incontinence, akrasia, or weakness of will. However, this kind of failure is much less discussed in the corporate case. And, (...) where it is discussed, the view is that corporations are less prone to weakness. Here, I argue that proponents of corporate responsibility should say that corporations can and often do instantiate weakness of the will, and that this is important to recognize. Weakness of the will requires certain capacities that these proponents typically take corporations to have. And once this is appreciated, we can assess how corporate weakness might proceed differently than how it does for individuals. We can also begin a conversation about how best to meet the distinctive challenges for recognizing and correcting corporate weakness, using a number of resources from management scholarship.

The discovery, more than 60 years ago, of a mutant mouse with a short tail led to the birth of the new field of developmental genetics. Over the years since, numerous investigators have probed the biology of the original short‐tail mutation at the T locus, as well the naturally‐occurring t haplotypes that were uncovered as a result of their interaction with this mutation. Although the T locus ranks among the best characterized developmental loci in the mouse, it was not among (...) the first to be cloned. This situation has now been rectified with two recent reports from Herrmann, Lehrach and their colleagues. While the T locus is expressed uniquely in the embryonic tissues predicted from the mutant phenotype, the gene itself, as well as the predicted amino acid sequence of the T product, show no strong homology to any known sequence. For the moment, at least, the mystery behind the function of the T locus still awaits definitive resolution. (shrink)
