Tracking theories of knowledge are widely known to have the consequence that knowledge is not closed. Recent arguments by Vogel and Hawthorne claim both that there are no legitimate examples of knowledge without closure and that the costs of theories that deny closure are too great. This paper considers the tracking theories of Dretske and Nozick and the arguments by Vogel and Hawthorne. We reject the arguments of Vogel and Hawthorne and evaluate the costs of closure denial for tracking theories (...) of knowledge. (shrink)

Most whistleblowers talk as if they never had a choice about whether to blow the whistle. This doesn't mean they acted suddenly, or impulsively, only that they believe they could not have done otherwise. Trying to make sense of this near universal answer to the question "Why did you do it?" the essay draws on narrative theory. Narrative theory distinguishes between actant and sender—that is, between actor and his or her values. This distinction helps to explain what it means to (...) face a difficult choice over something about which one feels one never had a choice. (shrink)

It remains a standing problem how and why the first nervous systems evolved. Molecular and genomic information is now rapidly accumulating but the macroscopic organization and functioning of early nervous systems remains unclear. To explore potential evolutionary options, a coordination centered view is discussed that diverges from a standard input–output view on early nervous systems. The scenario involved, the skin brain thesis, stresses the need to coordinate muscle-based motility at a very early stage. This paper addresses how this scenario with (...) its focus on coordination also deals with sensory aspects. It will be argued that the neural structure required to coordinate extensive sheets of contractile tissue for motility provides the starting point for a new multicellular organized form of sensing. Moving a body by muscle contraction provides the basis for a multicellular organization that is sensitive to external surface structure at the scale of the animal body. Instead of thinking about early nervous systems as being connected to the environment merely through input and output, the implication developed here is that early nervous systems provide the foundation for a highly specific animal sensorimotor organization in which neural activity directly reflects bodily and environmental spatiotemporal structure. While the SBT diverges from the input–output view, it is closely linked to and supported by ongoing work on embodied approaches to intelligence to which it adds a new interpretation of animal embodiment and sensorimotor organization.

This volume covers a wide range of conceptual, epistemological and methodological issues in the philosophy of science raised by reflection upon medical science and practice.

The central dilemma concerning randomized clinical trials (RCTs) arises out of some simple facts about causal methodology (RCTs are the best way to generate the reliable causal knowledge necessary for optimally-informed action) and a prima facie plausible principle concerning how physicians should treat their patients (always do what it is most reasonable to believe will be best for the patient). A number of arguments related to this in the literature are considered. Attempts to avoid the dilemma fail. Appeals to informed (...) consent and mechanisms for minimizing the resulting harm are important for policy, but informed consent is problematic and mechanisms for minimization of harm do not address the dilemma. Appeals to some sort of contract model of justification are promising and illuminating. Keywords: randomized clinical trials, ethics CiteULike Connotea Del.icio.us What's this? (shrink)

It is often claimed that a clinical investigator may ethically participate (e.g., enroll patients) in a trial only if she is in equipoise (if she has no way to ground a preference for one arm of the study). But this is a serious problem, for as data accumulate, it can be expected that there will be a discernible trend favoring one of the treatments prior to the point where we achieve the trial's objective. In this paper, I critically evaluate Benjamin (...) Freedman's 'clinical equipoise' solution to this dilemma. I argue that Freedman actually puts forth at least two distinct contrasts - one in terms of community vs. individual equipoise, and another concerning clinical vs. theoretical equipoise - and that neither of them resolves the dilemma. I then make a proposal for a more adequate account of how to think about the circumstances under which entering subjects in trials would be justified - a 'sliding-scale equipoise' that arises out of a discussion of patients' values.

An Invitation to Formal Reasoning introduces the discipline of formal logic by means of a powerful new system formulated by Fred Sommers. This system, term logic, is different in a number of ways from the standard system employed in modern logic; most striking is its greater simplicity and naturalness. Based on a radically different theory of logical syntax than the one Frege used when initiating modern mathematical logic in the 19th Century, term logic borrows insights from Aristotle's syllogistic, Scholastic (...) logicians, Leibniz, and the 19th century British algebraists. Term logic takes its syntax directly from natural language, construing statements as combinations of pairs of terms, where complex terms are taken to have the same syntax as statements. Whereas standard logic requires extensive 'translation' from natural language to symbolic language, term logic requires only 'transcription' into the symbolic language. Its naturalness is the result of its ability to stay close to the forms of sentences usually found in every day discourse. Written by the founders of the term logic approach, An Invitation to Formal Reasoning is a unique introduction and exploration of this new system, offering numerous exercises and examples throughout the text. Summarising the standard system of mathematical logic to set term logic in context, and showing how the two systems compare, this book presents an alternative approach to standard modern logic for those studying formal logic, philosophy of language or computer theory. Fred Sommers is Professor Emeritus, Brandeis University, USA; George Englebretsen is Professor of Philosophy, Bishop's University, Canada. (shrink)

A discussion is going on in cognitive science about the use of representations to explain how intelligent behavior is generated. In the traditional view, an organism is thought to incorporate representations. These provide an internal model that is used by the organism to instruct the motor apparatus so that the adaptive and anticipatory characteristics of behavior come about. So-called interactionists claim that this representational specification of behavior raises more problems than it solves. In their view, the notion of internal representational (...) models is to be dispensed with. Instead, behavior is to be explained as the intricate interaction between an embodied organism and the specific make up of an environment. The problem with a non-representational interactive account is that it has severe difficulties with anticipatory, future oriented behavior. The present paper extends the interactionist conceptual framework by drawing on ideas derived from the study of morphogenesis. This extended interactionist framework is based on an analysis of anticipatory behavior as a process which involves multiple spatio-temporal scales of neural, bodily and environmental dynamics. This extended conceptual framework provides the outlines for an explanation of anticipatory behavior without involving a representational specification of future goal states. (shrink)

A central idea in moral and political philosophy, 'autonomy' is generally understood as some form of self-governance or self-direction. Certain Stoics, modern philosophers such as Spinoza, and most importantly, Immanuel Kant, are among the great philosophers who have offered important insights on the concept. Some theorists analyze autonomy in terms of the self being moved by its higher-order desires. Others argue that autonomy must be understood in terms of acting from reason or from a sense of moral duty independent of (...) the passions. Autonomy seems closely related to the notion of freedom, but in what sense: freedom from coercion, freedom from psychological constraints, or freedom from material necessity? Various approaches to these and similar questions yield different implications for public policy. Is capitalism, social democracy or socialism more favorable to autonomy? The essays in this volume address these important questions. (shrink)

John Stuart Mill underwent a mental crisis in the 1820s. He emerged from it, argues Fred Wilson, with a new understanding of the notion of introspective analysis more dequare as an empirical method than the sort of analysis that had been used by earlier utilitarian thinkiers such as Bentham and James Mill. Wilson's study places Mill's innovations in the context of earlier work in ethics and perception and of subsequent developments in the history of psychology. He shows the significance (...) of these topics with which Mill was concerned. The more adequate notion of introspective analysis enabled the younger Mill to reply to criticisms of various empiricist and utilitarian positions cencering the analysis of relations, the nature of our percievings of physical objects, the status of science of economics, and the nature of the utilitarian principle itself. Mill was thus able to reject the quantitative hedonism of his predecessors and to introduce qualitative hedonism in its place. Wilson suggest that the long tradition that views Mill's qualitative hedonism as inconsistent is mistaken, as area a variety of criticisms of his work in the psychology of perception and the philosophy of economics. A better grasp of the background of Mill's views of psychology and the philosophy of psychology easily shows the critics to be mistaken. (shrink)

Ethnic cleansing and other methods of political and social exclusion continue to thrive in our globalized world, complicating the idea that unity and diversity can exist in the same society. When we emphasize unity, we sacrifice heterogeneity, yet when we stress diversity, we create a plurality of individuals connected only by tenuous circumstance. As long as we remain tethered to these binaries, as long as we are unable to imagine the sort of society we want in an age of diversity, (...) we cannot achieve an enduring solution to conflicts that continue unabated despite our increasing proximity to one another. By envisioning the public as a multivoiced body, Fred Evans offers a solution to the dilemma of diversity. The multivoiced body is both one and many: heterogeneous voices that at once separate and bind themselves together through their continuous and creative interplay. By focusing on this traditionally undervalued or overlooked notion of voice, Evans shows how we can valorize simultaneously the solidarity, diversity, and richness of society. Moreover, recognition of society as a multivoiced body helps resists the pervasive countertendency to raise a chosen discourse to the level of "one true God," "pure race," or some other "oracle" that eliminates the dynamism of contesting voices. To support these views, Evans taps the major figures and themes of analytic and continental philosophy as well as modernist, postmodernist, postcolonial, and feminist thought. He also turns to sources outside of philosophy to address the implications of his views for justice, citizenship, democracy, and collective as well as individual rights. Through the seemingly simple conceit of a multivoiced body, Evans straddles both philosophy and political practice, confronting issues of subjectivity, language, communication, and identity. For anyone interested in moving toward a just society and politics, _The Multivoiced Body_ offers an innovative approach to the problems of human diversity and ethical plurality. (shrink)

The modern theory of computability is based on the works of Church, Markov and Turing who, starting from quite different models of computation, arrived at the same class of computable functions. The purpose of this paper is the show how the main results of the Church-Markov-Turing theory of computable functions may quickly be derived and understood without recourse to the largely irrelevant theories of recursive functions, Markov algorithms, or Turing machines. We do this by ignoring the problem of what constitutes (...) a computable function and concentrating on the central feature of the Church-Markov-Turing theory: that the set of computable partial functions can be effectively enumerated. In this manner we are led directly to the heart of the theory of computability without having to fuss about what a computable function is.The spirit of this approach is similar to that of [RGRS]. A major difference is that we operate in the context of constructive mathematics in the sense of Bishop [BSH1], so all functions are computable by definition, and the phrase “you can find” implies “by a finite calculation.” In particular ifPis some property, then the statement “for eachmthere isnsuch thatP” means that we can construct a functionθsuch thatP)for allm. Church's thesis has a different flavor in an environment like this where the notion of a computable function is primitive.One point of such a treatment of Church's thesis is to make available to Bishopstyle constructivists the Markovian counterexamples of Russian constructivism and recursive function theory. The lack of serious candidates for computable functions other than recursive functions makes it quite implausible that a Bishopstyle constructivist could refute Church's thesis, or any consequence of Church's thesis. Hence counterexamples such as Specker's bounded increasing sequence of rational numbers that is eventually bounded away from any given real number [SPEC] may be used, as Brouwerian counterexamples are, as evidence of the unprovability of certain assertions.

We consider notions of boundedness of subsets of the natural numbers ℕ that occur when doing mathematics in the context of intuitionistic logic. We obtain a new characterization of the notion of a pseudobounded subset and we formulate the closely related notion of a detachably finite subset. We establish metric equivalents for a subset of ℕ to be detachably finite and to satisfy the ascending chain condition. Following Ishihara, we spell out the relationship between detachable finiteness and sequential continuity. Most (...) of the results do not require countable choice. (shrink)

The mortality and morbidity resulting from noncommunicable diseases including cancer in sub- Saharan Africa are predicted to overtake that of infectious diseases by the year 2030. Esophageal cancer is on the increase in Tanzania. This study estimates risk factors for esophageal cancer, ethical issues and the level of awareness of cancer related services among adults in rural Kilimanjaro. A cross sectional descriptive study was conducted of adults aged 18 years and above in three wards, namely, Kahe, mabogini and Arusha Chini, (...) Moshi Rural District, Kilimanjaro region. Face-to-face interviews were conducted with a total of 419 individuals. The mean age was 36.47 =13.49) years. Of those who participated, 211 were male and 60% reported to have completed primary education. A majority of participants were knowledgeable about esophageal cancer risk factors. Overall, 15% and 23% of the participants reported to have been smoking and drinking alcohol, respectively. Male respondents were almost three times more likely to be smokers as compared to female respondents. Moreover, people who were self-employed were about five times more likely to be smokers as compared to those who were unemployed.. Male respondents were almost two times more likely to be drinkers as compared to female respondents. Overall, the level of awareness of cancer related health services was about 70%. The study findings confirm that despite a good level of knowledge about risk factors for esophageal cancer, the practice of exposure to risk factors is alarmingly high. Awareness of where to seek cancer related health services was high with hospitals been mentioned by the majority though there was low understanding on modalities of treatment among adults in Rural Kilimanjaro. Intervention measures should aim at further increasing knowledge of cancer risk factors and reduce the practice of such risks. Ethical matters including truth telling, ageism and autonomy need to be addressed to improve the perception of cancer related health issues and health seeking behaviour. (shrink)

A very weak omniscience principle is formulated, related omniscience principlesare considered, and the theorem that a function of bounded variation is the difference of two increasing functions is shown to be equivalent to the omniscience principle WLPO. It is a so shown that an arbitrary function with located variation on an interval is the difference of two increasing functions.

Cognitive science's basic premises are under attack. In particular, its focus on internal cognitive processes is a target. Intelligence is increasingly interpreted, not as a matter of reclusive thought, but as successful agent-environment interaction. The critics claim that a major reorientation of the field is necessary. However, this will only occur when there is a distinct alternative conceptual framework to replace the old one. Whether or not a serious alternative is provided is not clear. Among the critics there is some (...) consensus, however, that this role could be fulfilled by the concept of a 'behavioral system'. This integrates agent and environment into one encompassing general system. We will discuss two contexts in which the behavioral systems idea is being developed. Autonomous Agents Research is the enterprise of building behavior-based robots. Dynamical Systems Theory provides a mathematical framework well suited for describing the interactions between complex systems. We will conclude that both enterprises provide important contributions to the behavioral systems idea. But neither turns it into a full conceptual alternative which will initiate a major paradigm switch in cognitive science. The concept will need a lot of fleshing out before it can assume that role.

In lieu of an abstract, here is a brief excerpt of the content:The Logic of Probabilities in Hume's Argument against Miracles Fred Wilson The position is often stated that Hume's discussion of miracles is inconsistent with his views on the logical or ontological status oflaws ofnature and with his more general scepticism. Broad, for one, has so argued.1 Hume's views on induction are assumed to go somethinglike this. Any attempt to demonstrate knowledge ofmatters offact presupposes causal reasoning, but the (...) latter is based not on any perception of necessary connections, but on an unreasoned expectation that because events have been constantly conjoined in the past they will be constantly conjoined in the future. The fact that our past experience gives rise to certain expectations provides absolutely no reason to think that these expectations will be fulfilled. But this is forgotten as soon as he turns to the topic of miracles where the argument requires certain assumptions about laws of nature. Here he claims that the laws of nature arebased upon afirm andunalterable experience and dismisses what he apparently admits to be strong evidence for miracles on the basis of the claim that such events are absolutely impossible. The inconsistency between the discussion of miracles and the earlier discussions of induction and causality is clear. Nonetheless, there is a certain implausibility to this claim that makes it a difficult one to entertain seriously, since it is unlikely that a philosopher as careful as Hume would have failed to recognize the inconsistency if it existed. What I propose here to argue is that there is in fact no inconsistency, and that this becomes clear once one places the discussion ofmiracles in the broader context ofthe overall argument ofthe first Enquiry. In particular, the charge ofinconsistency disappears once one eliminates the caricature ofHume's views on causal reasoning upon which it rests. To come to grips with the discussion of miracles in Hume it is necessary to place that discussion in its historical context. In the generally empiricist atmosphere that developed in Britain following the mid-seventeenth century civil wars, the general defence of the reasonableness of Christianity consisted of two parts. First, it washeldthatrational argument, whether causal or teleological orboth, could yield a reasonable belief that a deity ofa more or less traditional sort existed. Then, second, in order to establish further that Jesus was the Son ofGod it was held that one could rely upon a chain oftestimony Volume XV Number 2 255 FRED WILSON leading back from the present to the past to infer the existence of miracles testifying to the divinity ofJesus. Hume attacks this second inference in the essay on miracles andthe first in the essay that follows in the Enquiries on God's particular providence (the themes of which are developed more fully in the Dialogues on Natural Religion). Given the central place that the appeal to miracles held in Christian apologetics in the 17th and 18th centuries, Hume's systematic attack on the argument from miracles constituted a clear attack on Christianity. To be sure, Hume's argument would never have persuaded JohnWesley, but that would hardly have surprised Hume himself, nor should it surprise us: those in the grips of religious enthusiasm, whether it be John Wesley or Jimmy Swaggart, will hardly be persuaded by rational argument, however much it is still true that they ought to be persuaded by it. The appeal to miracles tojustify specifically Christian beliefs had a long history. One can find it already in the late Roman period in Eusebius. Muslim thinkers were to challenge this traditional defence by arguing that chains oftestimony become more unreliable the longer they become. As for their own Islamic beliefs, these they admitted had also to be justified by an appeal to miracles, but there was, it was claimed, a unique self-justifying miracle in the Koran, the specially revealed Word of God. The critical theme of the Muslim apologists, that the longer a chain of testimony the less assurance it gives of the fact that a miracle had occurred, was developed in Britain in the 17th and 18th centuries.6 It seems to have been introduced by the Oxford orientalist Edward Pocock who had discovered this line of Muslim apologetics while...

There have been significant changes in what economists include in the category of investment over the last six decades. The US government agency that compiles national income date, the Bureau of Economic Analysis, has tried to keep up with these changes, but it has not succeeded. The resulting tension between economic theory and official data can be overcome by adopting a different theoretical lens. Work on social reproduction and social investment suggests a more coherent definition of investment than that offered (...) by mainstream economists. The paper then contrasts the measurement of investment in the government data with a calculation of investment derived from this new approach. The results show that business investment is dwarfed by the combined investment made by government and households. This finding suggests that business investment is not the key engine that powers the economy. This has significant implications for economic and social policies. (shrink)

In this article, we argue that shaming interventions and messages during Covid-19 have drawn the relationship between public health and shame into a heightened state of contention, offering us a valuable opportunity to reconsider shame as a desired outcome of public health work, and to push back against the logics of individual responsibility and blame for illness and disease on which it sits. We begin by defining shame and demonstrating how it is conceptually and practically distinct from stigma. We then (...) set out evidence on the consequences of shame for social and relational health outcomes and assess the past and present dimensions of shame in the context of the Covid-19 pandemic, primarily through a corpus of international news stories on the shaming of people perceived to have transgressed public health directions or advice. Following a brief note on shame (and policymaking) in a cultural context, we turn to the concept and practice of ‘shame-sensitivity’ in order to theorise a set of practical and adaptable principles that could be used to assist policymakers in short- and medium-term decision-making on urgent, tenacious, and emerging issues within public health. Finally, we consider the longer consequences of pandemic shame, making a wider case for the acknowledgement of the emotion as a key determinant of health. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume on the Abstract Idea of Existence: Comments on Cummins' "Hume on the Idea of Existence"1 Fred Wilson Hume'sviews on theconceptofexistence: thisisone ofthemore obscure parts of Hume's philosophy. Professor Cummins has done a valuable service simply by trying to unravel some ofthe puzzles; it is still more valuable for shedding as much light as it does on the issues. There are nonetheless problems with the interpretation that he (...) develops, and I would like to bring out some ofthese. I will address three questions: (a)What, more precisely, is the (abstract) idea ofexistence? (b)What is the notion of"necessity" as Hume would use it in connection with the notion that something exists "necessarily," or, contrarily, "contingently"? (c)Does it follow from the fact that whatever thing we conceive we conceive as existent that every thing necessarily exists? In order toanswerthese questions somethingwillhave tobe said about Hume's doctrine ofabstractideas. Butonall theseissues, Humeis often not so much inadequate as incomplete; and I shall suggest that a numberofpoints canbeilluminatedbylookingatthe historical context that Hume himselfcould take for granted. The upshot will not be that Hume's views are unproblematic, but only that they are perhaps less problematic than Professor Cummins makes out. I. Abstract Ideas In many respects, Hume's doctrine of ideas is fairly traditional. We think in terms ofideas. In particular, our capacity to think generally, and to use general terms, is a matter ofhaving abstract ideas. In this, Hume follows the views ofhis predecessors such as Locke, Descartes and the Port Royal logicians. Hume also adopts the principle that what is conceivable is possible. Again, he follows the same tradition ofLocke, Volume XVII Number 2 167 FRED WILSON Descartes and the Port Royal logicians. Where Hume differs from his predecessors is in his account of what precisely an abstract is. For Hume's predecessors, one forms an abstract idea by separation. Thus, for Locke, forming ideas by abstraction consists in "separating them from all other Ideas that accompany them in their real existence."2 This sortofseparation is the mechanism bywhich "the Mind makes the particular Ideas, received from particular Objects, to become general" (Essay, 2.11.9). The Port Royal logicians make the same point: abstraction occurs with respect to "choses... composées" when one "les considérant par parties, et comme par les diverses faces qu'elles peuvent recevoir." In abstraction what is thus known is considered separately from the whole; either one considers "les parties séparément" in the case of"parties intégrantes," or one "peut séparer les choses en divers modes," or, finally, "quand une même chose ayant divers attributs, on pense à l'un sans penser à l'autre."3 The former occurs when, for example, we separate in thought the parts ofthe body. Thisis the simplestform ofabstraction. Berkeleyhas noproblems with this notion: "Iwill notdenyI can abstract, ifthatmay properlybe called abstraction, which extends only to the conceiving separately such objects, as is possible may really exist or be actually perceived asunder."4 Neither does Hume have problems with this notion; it is the basis of his—and Berkeley's—view that ideas are either simple or complex and that some of the complex ideas are a result of our combining simple parts in ways that are not found in reality, as, for example, in our idea ofthe New Jerusalem.5 It is the other two sorts ofabstraction that are more problematic. Consider the first of these two forms of abstraction. We begin with simple ideas ofsensation, for example, white (Essay, 2.3.1). One forms the abstract idea of white by separating the property white from the other qualities with which it is conjoined in the white particulars, for example, snow or milk (Essay, 2.21.73), that are given in sense experience. The resultingideais distinct from other ideas, for example, blue or heat (Essay, 2.12.1). The example given by Nicole and Arnauld is thatofthe geometers who explore the idea ofthree-dimensional space by considering first length alone, then area, and finally volumes or solids (which is the same, for these Cartesians as "corps," body) (Logique, 1.5). This is one form ofseparation. By this means one forms abstract... (shrink)
