In lieu of an abstract, here is a brief excerpt of the content:The Truth Will Set You Free, or How a Troubled Philosophical Theory May Help to Understand How People Talk About Their AddictionPatricia A. Ross (bio)Keywordsveridicality of narrative, contingency of theories, belief-behavior, causal connectionConsider the following proposition: If one were to recognize the unsatisfactory implications of maintaining a certain theoretical position, one would thereby be motivated to accept a more adequate theory, which would alter one's beliefs and, in turn, (...) alter the behaviors that are based upon those beliefs. Faith in this proposition is what motivates many of us to teach. But, alas...Allison Mitchell's argument for rethinking addiction intervention—in particular, rethinking twelve-step programs—is premised on this proposition. According to her argument, addicts function with an impoverished sense of self that is reflective of a grossly simplified form of philosophical materialism. By recognizing the limitations of this philosophically unconvincing view, and by, in effect, accepting a better, more complete materialism, addicts can come to modify their self-conception. This modification is instrumental to recovery.A careful consideration of the chain of events being proposed, and the problems with it, is helpful for understanding the limitations of her argument. There are four points that I consider in turn: (1) considering narratives can tell us something about the self-conception of addicts, (2) philosophical materialism can help us to understand and explain something about an addict's self-conception and how it is inadequate, (3) this sense of self is distinct from nonusers and the way in which it is distinct helps to understand the problem of addiction, and (4) a change in self-conception with respect to materialism helps recovery and, thus, our best intervention is one based on having addicts accept a full materialist theory of the self and not a pretheoretic one. [End Page 227]With respect to the first point, it should be noted that Mitchell's overall argument does not depend on whether or not it is true that narratives of addiction tell us something veridical about the self-conception of addicts. Such narratives may simply provide us with a potential theory—a possible worlds scenario—of how addicts conceive of themselves. Mitchell points this out herself. The narratives and the interpretation that she provides of these narrative, "are meant only to highlight a certain pattern of self-expression and conception that may in fact be common in persons who use mind-altering substances; the readings do not establish any empirical matters of fact or philosophical truths, nor do they prove any conclusions about how such persons (must) express themselves or conceive their nature" (Mitchell 2006, 214).Thus, what the argument is actually concerned with are the theoretical claims about the self-conception of addicts that are garnered from these narratives. Nevertheless, because the narratives provide the starting point for Mitchell's argument, it is worth thinking carefully about the epistemic status of this body of literature. In particular, could a consideration of such literature lead us astray in our endeavors to understand how addicts might misconceive of themselves and, if so, in what way? What sort of epistemic status does this information hold?Mitchell is motivated by Wittgensteinian analyses of the relationship between thought and language. The particular idea that she employs from Wittgenstein is that every act of self-expression, whether it is verbal or written narrative, reveals something about the conceptual framework with which the author is working. Thus, one can learn about the author of a narrative—one can acquire a sense of how that individual conceives of him- or herself—by looking at the language that is employed to talk about and describe him- or herself.Mitchell enumerates some problems with this approach. She mentions that the author may fail to make his or her intended sense clear to readers; that the reader's narrative expectations determine the interpretation given to the narrative; that literary narrative may be less direct, less ordinary than everyday uses of language; and that interpreting such narrative via philosophical framework may ascribe to people positions that are more precise and sophisticated than they actually intend (p. 213).Aside from these quite serious problems, it is necessary to recognize...

Hegel’s detailed analysis of subjective religion and his forceful rejection of the movement in his own political environment to deny civil liberties to Jewish citizens give us the conceptual tools to respond to our contemporary cases of religious extremism without violating the value of the autonomy and inherent worth of the thinking person that fanaticism tramples. This paper first addresses Hegel’s analysis of fanaticism, demonstrating that its rejection of the order of existing structures in favor of an abstract ideal (...) entails the Hegelian concept of spirit. When spirit’s implications are explored, it is evident that immediate religious certainty has the potential to elevate its adherents to thinking consciousness and therefore have the potential to follow its internal dialectics to the point where its convictions correspond with the major ethical principles upheld by modern states. Given the political freedom to explore their own latent truths and inconsistencies, subjective, even fanatical, religious consciousness can strengthen the state by its independent verification of the ideals embodied in the political community. In the meantime, autonomous reflection should be encouraged through free religious expression, including of religious views that run counter to the objective order of the state. However, any destructive attacks on this order must be confronted and stopped. These principles allow us to respond to the current Syrian refugee crisis, the controversy regarding municipal bans on burkinis in France, and violent, religiously-inspired terrorist attacks with clarity and consistency.

This paper argues that Aristotelian practical wisdom (phronêsis) is a state of conviction (pistis) in the goodness of our goals based on proper grounds. This state of conviction can only be achieved if rational arguments and principles agree with how things appear to us. Since, for Aristotle, passions influence appearances, they can support or undermine our conviction in the goodness of ends that are worth pursuing. For this reason, we cannot be practically wise without virtuous dispositions to experience appropriate (...) passions. Along the way, I argue that this reading allows us to explain the shortcomings of self-controlled and akratic agents. -/- . (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge Companion to Early Greek PhilosophyPatricia CurdA. A. Long, editor. The Cambridge Companion to Early Greek Philosophy. Cambridge: Cambridge University Press, 1999. Pp. xxxii + 427. Cloth, $54.95. Paper, $19.95.The Cambridge Companions are designed both to introduce and to survey, aims that anyone who teaches introductory courses knows are not fully compatible. The Cambridge Companion to Early Greek Philosophy is successful because its contributors have kept to (...) a uniform tone of mostly introduction, with some reference to recent developments and controversies in the field. There are sixteen essays, with a judicious mix of chapters on particular figures and on general topics.A. A. Long provides a helpful introduction, discussing the problems of dealing with the fragmentary evidence for these philosophers, and giving an account of the nature and scope of early Greek thought. (He also argues—not entirely persuasively—that we should give up the nineteenth century name "Presocratics" for these thinkers.) Jaap Mansfeld explains the problems of sources and doxography (the chapter is quite compressed and could be rather overwhelming for the newcomer to the area), while Keimpe Algra surveys Ionian cosmology. Carl Huffman provides a masterful discussion of early Pythagoreanism, attempting to sort out what we can and cannot be justified in claiming about Pre-Platonic Pythagoreanism. The chapters on individual thinkers mostly provide systematic overviews. Edward Hussey contributes an exemplary chapter on Heraclitus, and David Sedley one on Parmenides and Melissus (it is good to see Melissus treated seriously), with Richard McKirahan weighing in on Zeno (mostly on the paradoxes of motion but with some attention to the arguments against plurality). The discussions of individual Presocratics are rounded out with Daniel Graham's treatment of Empedocles' and Anaxagoras' responses to Parmenides, and C. C. W. Taylor on the Atomists. Sarah Broadie considers rational theology and James Lesher early Greek epistemology, while André Laks surveys ancient theories of soul, sensation, and thought. Paul Woodruff and Fernanda Decleva Caizzi provide chapters on the Sophists, the former discussing Protagoras and Gorgias, the latter, Protagoras and Antiphon. Mario Vegetti undertakes an examination of the notion of causation in early Greek thought, and Diskin Clay explores the poetics of the Presocratic philosophers. The book opens with short discussions—three paragraphs devoted to life, sources, and works for each of the thinkers who figure in the period (in alphabetical rather than even roughly chronological order), a chronological chart, and a map. There is a large and useful—though necessarily selective— bibliography (supplemented in the notes to some chapters by references to articles that are not included in the main bibliography), an index locorum, and an index of names and subjects that [End Page 429] includes modern scholars "only if their views are cited in the main text or discussed in footnotes" (which makes it difficult to use in tracking down references). Unfortunately, as in all the Cambridge Companions, notes are at the end of articles rather than at the foot of the page, making necessary a fair bit of flipping while reading.How well do the contributors succeed in meeting the needs of the intended readers of the series? For the most part, very well; the novice reader will find this an accessible guide to Early Greek philosophy. The various discussions are solid and well-informed, and the authors have indicated issues and interpretations that are controversial (for example, Taylor takes time to consider objections to his earlier criticism of Vlastos on the connection between atomistic metaphysics and ethics, and Hussey is careful to note the traditional flashpoints of disagreement in Heraclitus interpretation). It is also good that some of the Sophists are included (it is worth considering how viable the traditional distinction between the Sophists and the Philosophers really is), and inclusion of both the medical tradition and the issue of poetics is very welcome. Further chapters considering in more detail the cosmologies of post-Milesians (including Parmenides) and on the philosophical uses made of the early Greek thinkers by Plato and Aristotle would have rounded things out, but these would have made an already big book bigger. As perhaps befits an introductory survey, most of the interpretations lean to the traditional - someone looking for... (shrink)

We can see from the analysis set out here that the two accounts that were the focus of consideration are complementary to one another. It has been my contention that a problem like specifying a concept such as ‘refrain’ is highly complex. One part of it is the problem of determining the relation between the action (or event) and the result. Another part of the problem is that of describing the event itself; what kind of an event is it? These (...) two projects are related and so it is clear that the results must be consistent. However, it is equally clear that the definition which is useful for one project is not the same as that which is helpful for another. The point is that it should not be assumed that an account that initially looks incompatible with one's own must be refuted. It is sometimes better to consider what is needed for a complete account, and whether many different approaches may contribute pieces to the puzzle.We have here one puzzle piece: an analysis of refraining. It should not be assumed that we have thereby completed the puzzle of omission, but omission can be approached the same way; that is, by coordinating parallel projects.Accordingly, the first benefit of the present analysis is that it sets up an approach which is modular in nature. It allows for parallel projects to be pursued separately and coordinated. This kind of approach is sorely needed in this area to counter unproductive dispute.To see how such an approach can be applied to further problems profitably consider the following persistent controversy. Many philosophers are at odds over the importance of the notion of duty, or more informally, reasonable expectation in the understanding of refraining. A number of them (e.g., Hart and Honore, John Casey, and Phillipa Foot) hold that the determining feature for the ascription of responsibility to an agent for not doing something to prevent a harm (say, a death) is the presence of a duty or reasonable expectation that the agent do something about the situation. For example, John Casey holds, “If a man does not do x, we cannot properly say that his not doing x is the cause of some result y, unless in the normal course of events he could have been expected to do x.” Casey, Actions and Consequences (1978).Other philosophers object that a person can cause a result by refraining from (causally) preventing it, and that such an event can be explained without any reference to duty. These two views appear to conflict, but in fact they are both right (but both incomplete). The reason that the above statements are generally thought to constitute a disagreement is that ‘refrain’ is generally taken as the fundamental term of analysis for omissions. Thus, if Casey says, “If a man does not do x...” he is taken to mean “...if a man refrains from doing x...” But he need not mean that. He may mean to say only that the man failed to do x. See my analysis in “Contemplating Failure,” supra note 10. Failing to do something can be, and ordinarily is, thought of as stronger than simple nonaction. But it is much weaker than refraining. For one thing, it has no awareness requirement. Thus, an account like Casey's can explain the ascription of responsibility and the presence of an omission where Green's account (or the account offered here) cannot, and vice versa. Casey's view can explain why we hold (or at least that we hold) responsible the night watchman who forgets to check one of the windows, the bookkeeper who (accidentally) omits an entry in the accounts, or the private duty nurse who fails to prevent a death by falling asleep on the job. No refraining is present in any of these cases. Consequently, any thesis based on refraining alone cannot explain them. But in many cases refraining is precisely what is important, and Green (and others of the same persuasion) are correct to point out that no reference to duty is necessarily required to account for these cases. Analysis based on refraining best explains intentional or conscious omission. Analysis based on duty or reasonable expectation is the only way to explain unconscious omission. More often than not, both elements are present. A complete account of omission needs both. So here again, the better way to view these putatively competing accounts is as parallel projects which work toward a common, but complex end. The approach taken here allows for this kind of much needed coordination. The second benefit of the present analysis is that it clarifies and focuses on the significance of the mental element of refraining. Refraining is conscious omission. Consciousness and omission are its distinguishing features. The effects of seeing the concept this way are pervasive. Here is one example. If I refrain from reporting my full income to the IRS, I have committed fraud, and punitive or even criminal sanctions may be reasonable. If I fail to report my full income through ignorance or mistake (say, I misunderstood the instructions) correcting the error and requiring payment is reasonable, but certainly criminal sanction is not. This oversimplifies the distinction, but it illustrates the focus of my pursuit.With regard to positive actions, law and philosophy have long recognized this important distinction as manifested in the difference between negligence and intentional tort, or manslaughter and murder. Due (I think) to the extraordinary flexibility of language and the weakness and variability of social conventions regarding omissions, this distinction has not been clearly articulated. I think such an analysis is worth pursuing. The present account is one step in that pursuit. (shrink)

An oracle was reported to have said, "No one is wiser than Socrates." And in fact it was Socrates’ life’s work to interpret these words, which demanded and defined the practice of philosophy. Each of these original essays attends carefully to the specifics of the _Apology_, looking to its dramatic details, its philosophic teaching, and its complexity as a work of writing to bring into focus the "Socrates" of the _Apology_. Overall, the contributors, distinguished scholars of ancient philosophy, share a (...) belief in the unity of the letter and the spirit of Platonic philosophy: the conviction that the Platonic text cannot be reached except through reading and cannot be read except through thinking. In this way, the readings in this volume mirror Socrates’ own hermeneutical practice of uniting the demands of the mind and the demands of the text—the Socratic "examination." The result, true to the Socratic injunction that the unexamined life is not worth living, continues that practice of examination, here offering a reexamination of Socrates in the _Apology_. (shrink)

ABSTRACT In the current debate between scientific realism and empiricism, both sides seem to embrace some sort of structuralism as an important component of their descriptions of science. The structural realism is generally presented in two versions: one ontic and the other epistemic. It has been argued that that epistemic structural realism is close, if not identical, to a Kantian approach. We aim to show that this is not the case, since ESR, being fundamentally a realist position, cannot be fully (...) consistent with a transcendental approach. Such a position is better called transcendental structuralism, an alternative that we believe is worth being investigated on its own. In this paper, we will take Henry Allison's interpretation of transcendental idealism as a starting point to establish the distinctions between ESR and TS.RESUMO No debate atual entre realismo científico e empirismo, ambos os lados parecem abraçar algum tipo de estruturalismo como um componente importante de suas descrições sobre a ciência. O realismo estrutural é geralmente apresentado em duas versões: uma ôntica e outra epistêmica. Tem-se argumentado que o realismo estrutural epistêmico, por sua vez, é próximo, se não idêntico, a uma abordagem kantiana. Nosso objetivo neste artigo é mostrar que esse não é o caso. Sendo o ESR fundamentalmente uma posição realista, queremos defender que ele não pode ser totalmente compatível com uma abordagem transcendental. Uma posição kantiana mais coerente é aqui defendida sob o nome de estruturalismo transcendental. Neste artigo, partiremos da interpretação de Henry Allison do idealismo transcendental para estabelecer as devidas distinções entre ESR e TS. (shrink)

Gottlob Frege famously rejects the methodology for consistency and independence proofs offered by David Hilbert in the latter's Foundations of Geometry. The present essay defends against recent criticism the view that this rejection turns on Frege's understanding of logical entailment, on which the entailment relation is sensitive to the contents of non-logical terminology. The goals are (a) to clarify further Frege's understanding of logic and of the role of conceptual analysis in logical investigation, and (b) to point out the extent (...) to which his understanding of logic differs importantly from that of the model-theoretic tradition that grows out of Hilbert's work.

This paper examines the connection between model-theoretic truth and necessary truth. It is argued that though the model-theoretic truths of some standard languages are demonstrably ''''necessary'''' (in a precise sense), the widespread view of model-theoretic truth as providing a general guarantee of necessity is mistaken. Several arguments to the contrary are criticized.

This paper defends the view that Frege’s reduction of arithmetic to logic would, if successful, have shown that arithmetical knowledge is analytic in essentially Kant’s sense. It is argued, as against Paul Benacerraf, that Frege’s apparent acceptance of multiple reductions is compatible with this epistemological thesis. The importance of this defense is that (a) it clarifies the role of proof, definition, and analysis in Frege’s logicist works; and (b) it demonstrates that the Fregean style of reduction is a valuable tool (...) for those who would investigate the nature of arithmetical knowledge.

The primary purpose behind effectiveness research is to determine whether a treatment with demonstrated efficacy has utility when administered to the general population. The main questions these studies are meant to answer are these: Can the typical patient respond to treatment? Is the treatment acceptable to the typical patient? Can the treatment be administered safely and in its entirety in the typical treatment setting? Is the treatment under study significantly better than the community standard of care both from a cost (...) and outcome perspective? Answering these questions is meant to provide sufficient information to providers and policymakers so that effective interventions can be adopted and become the new community standard. For this research to make a meaningful impact on a provider and policymaker's decision to change the status quo, study interventions should be compared to the existing community standard of treatment, often referred to as treatment as usual (TAU). From an ethical perspective, this decision may not always be the safest choice. In some populations, TAU may mean no treatment at all, and in others TAU may be worse than withholding treatment. The effectiveness researcher is then caught between the pull to do no harm and the need for research to have an impact on change. The purpose of this article is to highlight certain conditions when TAU is ethically acceptable and to discuss alternatives when TAU may be an unethical treatment condition. For purposes of precision, we focus exclusively on psychotherapy effectiveness research rather than system-intervention research or medication-intervention research. (shrink)

Because of historical mistreatment of ethnic minorities by research and medical institutions, it is particularly important for researchers to be mindful of ethical issues that arise when conducting research with ethnic minority populations.

We highlight 2 factors, skepticism and mistrust by ethnic minorities about research and current inequities in the mental health care system, that researchers should consider when (...) developing psychosocial interventions studies that include ethnic minorities.

This thesis is an examination of Frege's logicism, and of a number of objections which are widely viewed as refutations of the logicist thesis. In the view offered here, logicism is designed to provide answers to two questions: that of the nature of arithmetical truth, and that of the source of arithmetical knowledge. ;The first objection dealt with here is the view that logicism is not an epistemologically significant thesis, due to the fact that the epistemological status of logic itself (...) is not well understood. I argue to the contrary that on Frege's conception of logic, logicism is of clear epistemological importance. ;The second objection examined is the claim that Godel's first incompleteness theorem falsifies logicism. I argue that the incompleteness theorem has no impact on logicism unless the logicist is compelled to hold that logic is recursively enumerable. I argue, further, that there is no reason to impose this requirement on logicism. ;The third objection concerns Russell's paradox. I argue that the paradox is devastating to Frege's conception of numbers, but not to his logicist project. I suggest that the appropriate course for a post-Fregean logicist to follow is one which divorces itself from Frege's platonism. ;The conclusion of this thesis is that logicism has of late been too easily dismissed. Though several critical aspects of Frege's logicism must be altered in light of recent results, the central Fregean thesis is still an important and promising view about the nature of arithmetic and arithmetical knowledge.

A medical information commons is a networked data environment utilized for research and clinical applications. At three deliberations across the U.S., we engaged 75 adults in two-day facilitated discussions on the ethical and social issues inherent to sharing data with an MIC. Deliberants made recommendations regarding opt-in consent, transparent data policies, public representation on MIC governing boards, and strict data security and privacy protection. Community engagement is critical to earning the public's trust.

We describe and analyze 13 cases handled by our ethics consultation service (ECS) in which families requested continuation of physiological support for loved ones after death by neurological criteria (DNC) had been declared. These ethics consultations took place between 2005 and 2013. Patients’ ages ranged from 14 to 85. Continued mechanical ventilation was the focal intervention sought by all families. The ECS’s advice and recommendations generally promoted “reasonable accommodation” of the requests, balancing compassion for grieving families with other ethical and (...) moral concerns such as stewardship of resources, professional integrity, and moral distress. In cases we characterized as finitegoal accommodation, a “reasonable accommodation” strategy proved effective in balancing stakeholders’ interests and goals, enabling steady progress toward resolution. When a family objected outright to a declaration of DNC and asked for an indefinite accommodation, the “reasonable accommodation” approach offered clinicians little practical direction, and resolution required definitive action by either the family or the clinical team. Based on our analysis and reflections on these 13 cases, we propose ethically justified and practical guidelines to assist healthcare professionals, administrators, and ECSs faced with similar cases.

Whenever one asserts a claim of any kind, one engages in a commitment not just to that claim itself, but to a variety of other claims that follow in its wake, claims that, as we tend to say, follow logically from the original claim. To say that Smith and Jones are both great basketball players is to say something from which it follows that Smith is a great basketball player, that someone is a great basketball player, that there is something (...) at which Smith is great, and so on.

Designing for culture through intelligent tutoring systems is on the rise. The needs of military personnel to communicate and understand cultures other than their own in deployments, missions, and work-related assignments have strongly encouraged the creation of culturally aware tutoring systems (CATS) that teach about other cultures. This paper critically analyzes three systems (i.e., ELECT-BiLAT, Tactical Iraqi, and VECTOR) and the frameworks that guided the design and development process. The examination reveals that there is a need for comprehensive guidelines to (...) build CATS. Therefore, the Culture Based Model is offered as a framework to guide the design of culture-based information and communication technologies. (shrink)

Abstract:This essay suggests that the word decolonial offers analytic power for feminist historians of women. As a category, it creates interpretive space for female experience beyond the elite/subaltern binary, where arguably most women live and work in the modern period. As a reading practice, the decolonial fosters intellectual awareness of social and intellectual practices that neither address the state, as in “anti-imperialism,” nor proffer counter nationalism or counter racialization as responses to coloniality. Offering examples from the archive, the media, and (...) teaching, this essay describes the decolonial as a productive site of women's agency in domains all too easily overlooked when historians focus on the conventional categories of state and nation.

A comprehensive look at fictive letters in Greek literature from Homer to Philostratus, first published in 2001. It includes both embedded epistolary narratives in a variety of genres, and works consisting solely of letters, such as the pseudonymous letter collections and the invented letters of the Second Sophistic. The book challenges the notion that Ovid 'invented' the fictional letter form in his Heroides and considers a wealth of Greek antecedents for the later European epistolary novel tradition. Epistolary technique always problematizes (...) the boundaries between fictionality and reality. Based on a process of selection and self-censorship, the letter is a construction, not a reflection, of reality. The author bypasses the question of sincerity for a close look at epistolary self-representation, the function of the letter form and the nature of the relationship between writer and reader in a wide range of ancient Greek texts.
