The class of defeasible logics is only vaguely defined – it is defined by a few exemplars and the general idea of efficient reasoning with defeasible rules. The recent definition of the defeasible logic DL(∂||) introduced new features to such logics, which have repercussions that we explore. In particular, we define a class of logics that accommodates the new logic while retaining the traditional properties of defeasible logics.

Controlled human infection challenge studies (CHIs) involve intentionally exposing research participants to, and/or thereby infecting them with, micro‐organisms. There have been increased calls for more CHIs to be conducted in low‐ and middle‐income countries (LMICs) where many relevant diseases are endemic. This article is based on a research project that identified and analyzed ethical and regulatory issues related to endemic LMIC CHIs via (a) a review of relevant literature and (b) qualitative interviews involving 45 scientists and ethicists with relevant expertise. (...) In this article we argue that though there is an especially strong case for conducting CHIs in endemic (LMIC) settings, certain ethical issues related to the design and conduct of such studies (in such settings) nonetheless warrant particularly careful attention. We focus on ethical implications of endemic LMIC CHIs regarding (a) potential direct benefits for participants, (b) risks to participants, (c) third‐party risks, (d) informed consent, (e) payment of participants, and (f) community engagement. We conclude that there is a strong ethical rationale to conduct (well‐designed) CHIs in endemic LMICs, that certain ethical issues warrant particularly careful consideration, and that ethical analyses of endemic LMIC CHIs can inform current debates in research ethics more broadly.

This book is a sustained defense of the compatibility of the presence of idealizations in the sciences and scientific realism. So, the book is essentially a detailed response to the infamous arguments raised by Nancy Cartwright to the effect that idealization and scientific realism are incompatible.

Research on meditation and mindfulness practice has flourished in recent years. While much of this research has focused on well-being outcomes associated with mindfulness practice, less research has focused on how perception of self may change as a result of mindfulness practice, or whether these changes in self-perception may be mechanisms of mindfulness in action. This is somewhat surprising given that mindfulness derives from traditions often described as guiding people to realise and experience the non-separation of self from the world (...) or its ‘oneness’ with the whole of reality. The current study used a collective intelligence methodology, Interactive Management (IM), to explore the nature of oneness experiences. Five IM sessions were conducted with five separate groups of experienced meditators. Participants generated, clarified, and selected oneness self-perceptions they believed most characterised their experience both during meditation and in their everyday experience in the world. Each group also developed structural models describing how highly ranked aspects of oneness self-perceptions are interrelated in a system. Consistent themes and categories of oneness experience appeared across the five IM sessions, with changes in the sense of space (unboundedness), time, identity, wholeness and flow highlighted as most influential. Results are discussed in light of emerging theory and research on oneness self-perception and non-dual awareness. (shrink)

David hume is sometimes viewed as a skeptic who argues that none of our beliefs about the world are justified. this paper challenges that view by developing and explicating an account of justified belief that is compatible with hume's theories about belief formation, inference, and principles governing the association of ideas. it is noted that the resultant account bears some resemblance to contemporary causal/reliability views of justification.

The concept of intrinsic value has enjoyed a long, rich history. From the time of the ancient Greeks to the present day, philosophers have placed it at the foundation of much of their theorizing. This is especially true of G.E. Moore, who made it the cornerstone of his Principia Ethica. Yet this venerable concept has recently come under serious, sustained attack. My aim in this paper is to show that this attack has been unsuccessful.When Principia Ethica appeared, its impact on (...) the philosophical community was immediate and profound. Of course, much of what Moore had to say was, and continues to be, strongly disputed. The view that goodness is a simple nonnatural property has been criticized by many people and in many ways. Some have argued that goodness is an analyzable property. Others have argued that it is a natural property. Still others have argued, more radically, that goodness is not a property at all. But none of these critics has rejected the very idea of goodness. None of them, that is, has contended that to say of something that it is good is to speak nonsense. (shrink)

This paper identifies ‘savage numbers’ – number-like or number-replacing concepts and practices attributed to peoples viewed as civilizationally inferior – as a crucial and hitherto unrecognized body of evidence in the first two decades of the Victorian science of prehistory. It traces the changing and often ambivalent status of savage numbers in the period after the 1858–1859 ‘time revolution’ in the human sciences by following successive reappropriations of an iconic 1853 story from Francis Galton's African travels. In response to a (...) fundamental lack of physical evidence concerning prehistoric men, savage numbers offered a readily available body of data that helped scholars envisage great extremes of civilizational lowliness in a way that was at once analysable and comparable, and anecdotes like Galton's made those data vivid and compelling. Moreover, they provided a simple and direct means of conceiving of the progressive scale of civilizational development, uniting societies and races past and present, at the heart of Victorian scientific racism.

Pseudonymous mathematician Nicolas Bourbaki and his lesser-known counterpart E.S. Pondiczery, devised respectively in France and in Princeton in the mid-1930s, together index a pivotal moment in the history of modern mathematics, marked by international infrastructures and institutions that depended on mathematicians’ willingness to play along with mediated personifications. By pushing these norms and practices of personification to their farcical limits, Bourbaki’s and Pondiczery’s impersonators underscored the consensual social foundations of legitimate participation in a scientific community and the symmetric fictional character (...) of both fraud and integrity in scientific authorship. To understand authorial identity and legitimacy, individual authors’ conduct and practices matter less than the collective interpersonal relations of authorial assertion and authentication that take place within disciplinary institutions.

In this essay I argue that Albert would reject the need for a separate fourth mode of common personal supposition, and that his view of merely confused supposition has not been fully explicated by modern scholars. I first examine the various examples of conjunct descent given by modern scholars from his Perutilis logica , and show that Albert clearly adopts it in resolving the sophistic examples involved. Second, I explicate the view of merely confused supposition that Albert defends in his (...) Sophismata , and then attempt to answer the question: which view of merely confused supposition was his final view, the view articulated in the Perutilis logica or the view in the Sophismata ? I conclude that based upon his Sophismata view of merely confused supposition, Albert came to realize the logical strength his revised theory of personal supposition afforded, and consequently, that he is one of the earliest 14th-century logicians to adopt conjunct terminal descent to resolve various sophisms, a move which gave his theory of personal supposition a logical symmetry having two sorts of propositional descents to singulars, and two sorts of terminal descents to singulars.

In lieu of an abstract, here is a brief excerpt of the content:141 HUME AND CAUSAL INFERENCE Hume held that any time we reach by inference a belief about the existence or qualities of some object or event that we have not actually perceived, the inference is grounded in beliefs about causal relations holding between the object of belief and some other object or objects that have actually been experienced. I will examine here Hume's account of such causal inferences. There (...) are many places in the Treatise of Human Nature at which Hume seems to claim that causal inferences take place when and only when the percipient has had an extensive previous experience of objects of the respective types as regularly conjoined in relations of contiguity and temporal priority. It seems to me that reliance on these passages alone gives a distorted view of Hume's theory of causal inference. Contrary to appearances, Hume did not hold that extensive previous experiences of objects of the same types as properly conjoined is either necessary or sufficient for causal inference. Hume's view is more subtle and complicated, and there are important considerations of coherence and holism present in it. Getting Hume's view on this matter clear is important because it shows how he can escape some of the objections that have been laid against his theory, and it makes possible a reading of Hume as a causal realist. Hume's theory of inference provides the resources for drawing a distinction between accidental and genuine causal regularities and it is compatible with the view that causal relations (and not mere de facto regularities) hold among events in the world independently of their being perceived. The examination begins by looking at a different, but related, issue. Why does Hume think 142 that of the three types of association, only cause and effect association is capable of producing belief? Hume puts the question in the form of a possible objection to his account. For it may be said, that if all the parts of that hypothesis be true, viz. that these three species of relation are deriv'd from the same principles; that their effects in inforcing and inlivening our ideas are the same; and that belief is nothing but a more forcible and vivid conception of an idea; it shou'd follow, that that action of the mind may not only be deriv'd from the relation of cause and effect, but also from those of contiguity and resemblance. But as we find by experience, that belief arises only from causation, and that we can draw no inference from one object to another, except they be connected by this relation, we may conclude, that there is some error in that reasoning, which leads us into such difficulties. (T 107) It is important to note that Hume is talking here only about beliefs about the existence or situations of objects that have not been intuited or experienced. Beliefs about relations of ideas (e.g., that 2 + 2 = 4) are intuitions (or perhaps memories 2 of intuitions). Beliefs in the existence of things as experienced or in the previous existence of things as previously experienced automatically have the 3 vivacity of impressions or memory ideas. What Hume takes himself to need to explain is why cause and effect association allows for a transfer of this vivacity to an idea of an object or situation that has not itself been intuited or experienced and why 4 resemblance and contiguity association do not. If I see a green ball next to a red sweater, then I will normally subsequently believe that the green ball existed next to the red sweater at that time (at 143 least until my memories begin to lose vivacity). This is purely a matter of sense experience and memory. Now if I subsequently see a different red sweater (or the same sweater in a different location), I may be led to think of a green ball existing next to it purely through contiguity and resemblance association. But presumably I would not believe that a green ball existed next to the currently perceived red sweater unless I currently perceived a green ball or my belief was based on some 5 form of causal inference...

Baker and Detiénne argue that the results reported in Stone and Wang and Alea et al. should be contextualized within a broader historical and societal perspective that takes into account the co‐evolution of social interaction practices and technology‐mediated collaborative activities.

The development of possible worlds semantics for modal claims has led to a more general application of that theory as a complete semantics for various formal and natural languages, and this view is widely held to be an adequate (philosophical) interpretation of the model theory for such languages. We argue here that this view generates a self-referential inconsistency that indicates either the falsity or the incompleteness of PWS.

In this paper it is argued that the conjunction of linguistic ersatzism, the ontologically deflationary view that possible worlds are maximal and consistent sets of sentences, and possible world semantics, the view that the meaning of a sentence is the set of possible worlds at which it is true, implies that no actual speaker can effectively use virtually any language to successfully communicate information. This result is based on complexity issues that relate to our finite computational ability to deal with (...) large bodies of information and a strong, but well motivated, assumption about the cognitive accessibility of meanings of sentences ersatzers seem to be implicitly committed to. It follows that linguistic ersatzism, possible world semantics, or both must be rejected. (shrink)

Creolizing Hegel brings together transdisciplinary scholars presenting various approaches to creolizing the work of Hegel. The essays in this volume take Hegelian texts and themes across borders of method, discipline, and tradition.

Kant's response to ‘Hume's problem’ in his analysis of the a priori structure of causality as law-governed succession in the Second Analogy of Experience has unquestionably overshadowed the account of simultaneity (Zugleichsein), which follows in the Third Analogy. The analysis of simultaneity in the first Critique relies entirely upon that of succession and is ultimately no more than a more complicated variant of the causal dependence of substances: two objects are experienced as simultaneous only when each of those objects grounds (...) some determination of the other, that is when they are reciprocally determined in dynamic community. By investigating Kant's remark in the third Critique that the experience of the sublime “makes simultaneity intuitable” this paper develops a Kantian analysis of simultaneity that is irreducible to the more prominent analysis of causal succession. This more robust account of simultaneity is then seen to play an essential role in the constitution of the objects of perception (and not only the regulation of their relations) as thematized in the Axioms of Intuition in the Critique of Pure Reason.

Over the last decade, the news media have reported on corporate scandals involving high-profile organizations such as Arthur Anderson, AOL Time Warner,Enron, Halliburton, Kmart, and Xerox. In 2001, the Conference Board of Canada noted that supplier relationships represent some of the most common ethical problems in the private sector, and estimated that 95% of corporations in the United States and 86% of corporations in Canada have implemented ethical codes of conduct and are espousing their commitment to building relationship with ethical (...) suppliers. While a significant amount of research on corporate ethics has been published (for examples see Akaah and Riordan 1989; Cullen et al. 2003; Román and Ruiz 2005; Schminke et al. 2005; and Weaver et al. 1999a, 1999b), what still remains unknown is how and when a supplier’s ethical code of conduct matters to the buyer making decisions regarding their choice of suppliers.

DESPITE THE WELL-KNOWN historical significance of Aristotle’s doctrine of the productive or active intellect it is not unusual to find contemporary discussions treating the doctrine as an excrescence on the text of the De anima, a work, it is frequently nowadays supposed, in which an otherwise securely naturalistic epistemology and rational psychology are developed. Although the doctrine of the intellectus agens is found only in one place in Aristotle’s extant texts, the third book of the De anima, I shall nonetheless (...) maintain that an argument can be ferreted out of Aristotle’s discussion that establishes that the doctrine can be seen to follow from principles that are fundamental to Aristotle’s thought. I shall call this an “Aristotelian” argument for nous poiêtikos because of the fact that the argument obviously is not found, as I state it, on the surface of Aristotle’s text. I claim that there is a significant sense in which it is there, but that one must dig for it or, as I just put it, ferret it out. In a schematic form, the Aristotelian argument goes as follows.

My aim is to rekindle interest in David Lewis's (1983) infamous but neglected Mixed Theory of mental states. The Mixed Theory is a mix of physicalism and functionalism designed to capture the intuitions that both Martians and abnormal human Madmen can be in pain. The Mixed Theory is widely derided. But I offer a new development of the Mixed Theory immune to its most prominent objections. In doing so, I uncover a new motivation for the Mixed Theory: its unique ability (...) to explain cases in which it is plausibly indeterminate whether something is in pain. The Mixed Theory, whether or not it is ultimately correct, at least deserves renewed attention. (shrink)

Examining how, and to what effect, the phrase “truly international” became central to the rhetoric and organization of the American-hosted 1950 International Congress of Mathematicians, this essay traces the negotiation of a “truly international” discipline from mathematicians’ first international congresses around the turn of the century across two world wars and their divisive interlude. Two failed attempts to host international congresses of mathematicians in the United States, for 1924 and 1940, defined the stakes for those who became the principal organizers (...) for 1950. Combining American organizational records with contexts and sources that extend across and beyond traditional mathematical centers in Europe and North America, the essay shows how a small cohort of American mathematicians marshaled an emphatic but ambiguous “international” rhetoric to guide policies and command cooperation and support while responding to persistent challenges. Their adaptations and compromises left a lasting mark on the terms and achievements of international inclusion, cooperation, and hegemony in mathematics. (shrink)

Astronomer Charles Piazzi Smyth’s 1864–65 expedition to measure the Great Pyramid of Giza was planned around a system of linear measures designed to guarantee the validity of his measurements and settle ongoing uncertainties as to the Pyramid’s true size. When the intended system failed to come together, Piazzi Smyth was forced to improvise a replacement that presented a fundamental challenge to the metrological enterprise upon which his system had been based. The astronomer’s new system centered around a small lump of (...) basalt, now held at Cambridge’s Whipple Museum of the History of Science, which nucleated a wide array of material and scientific considerations. Through a bipartite analysis of the physical and narrative dimensions of Piazzi Smyth’s basalt Standard, I develop the implications of its use and construction for understanding the material constitution of scientific instruments. In particular, I illustrate how instruments are locally constituted through co-accountable systems and how their material features become integrally implicated in both their uses and meanings.
