This essay examines the strategies that Berkeley and Dharmakīrti utilize to deny that idealism entails solipsism. Beginning from similar arguments for the non-existence of matter, the two philosophers employ markedly different strategies for establishing the existence of other minds. This difference stems from their responses to the problem of intersubjective agreement. While Berkeley’s reliance on his Cartesian inheritance does allow him to account for intersubjective agreement without descending into solipsism, it nevertheless prevents him from establishing the existence of other finite (...) minds. I argue that Dharmakīrti, in accounting for intersubjective agreement causally, is able to avoid Berkeley’s shortcoming. I conclude by considering a challenge to Dharmakīrti’s use of inference that Ratnakīrti, a Buddhist successor of Dharmakīrti, advances in his “Disproof of the Existence of Other Minds” and briefly exploring a possible response that someone who wants to advocate an idealist position could give.

The growing recognition by cognitive neuroscientists that areas of vertebrate brains may be reused for multiple purposes either functionally during development or during evolution echoes a similar realization made by neuroscientists working on invertebrates. Because of these animals' relatively more accessible nervous systems, neuronal reuse can be examined at the level of individual identified neurons and fully characterized neural circuits.

We compare several methods of implementing the display (sequent) calculus RA for relation algebra in the logical frameworks Isabelle and Twelf. We aim for an implementation enabling us to formalise within the logical framework proof-theoretic results such as the cut-elimination theorem for RA and any associated increase in proof length. We discuss issues arising from this requirement.

Although aesthetics began with an interest in a teleological order, the classical question was largely disparaged and rejected in mainstream academic circles by the twentieth century. The two dogmas of musical modernism were the presumption of formalism and the assertion of aestheticism. Historically, philosophers defending the objectivity of aesthetic value focused on the question of Beauty per se. But what if beauty is descriptive of something else? Our conviction of justice runs deeper than convictions of beauty. This essay explores the (...) significance of human anticipation concerning justice and how moral conviction relates to music as an encounter with teleological convictions. Music is fundamentally an individualized philosophical experience engaging the question of order, based upon a universal teleological presupposition. We do not find the arts to be meaningful because we believe them to be beautiful; we ascribe beauty to that which we find to be deeply meaningful--a way-it-should-be. (shrink)

We re-express our theorem on the strong-normalisation of display calculi as a theorem about the well-foundedness of a certain ordering on first-order terms, thereby allowing us to prove the termination of systems of rewrite rules. We first show how to use our theorem to prove the well-foundedness of the lexicographic ordering, the multiset ordering and the recursive path ordering. Next, we give examples of systems of rewrite rules which cannot be handled by these methods but which can be handled by (...) ours. Finally, we show that our method can also prove the termination of the Knuth-Bendix ordering and of dependency pairs. Keywords: rewriting, termination, well-founded ordering, recursive path ordering.. (shrink)

We use a deep embedding of the display calculus for relation algebras ÆRA in the logical framework Isabelle /HOL to formalise a machine-checked proof of cut-admissibility for ÆRA. Unlike other “implementations”, we explicitly formalise the structural induction in Isabelle /HOL and believe this to be the first full formalisation of cutadmissibility in the presence of explicit structural rules.

We describe how we used the interactive theorem prover Isabelle to formalise and check the laws of the Timed Interval Calculus (TIC). We also describe some important corrections to, clarifications of, and flaws in these laws, found as a result of our work.

Five experiments explored how source reliability influences people’s tendency to rate statements as more credible when they were encountered earlier . Undergraduates read statements from one reliable source and one unreliable source. Statements read multiple times were perceived as more valid and were more often correctly identified on a general knowledge test than statements read once or not at all. This occurred at varying retention intervals whether the statements originated from a reliable or unreliable source, when people had little memory (...) for the statements themselves or their source, and when the discrediting information about the sources came either before or after reading the facts. While repetition aided recognition and source accuracy, both were unaffected by the reliability of the source. Consistent with the source monitoring framework, familiarity may create an illusion of truth for statements when people lack source-specifying cues, especially cues regarding the reliability of the source.

Biomedical and behavioral research may affect strongly held social values and thereby create significant controversy over whether such research should be permitted in the first place. Institutional review boards responsible for protecting the rights and welfare of participants in research are sometimes faced with review of protocols that have significant implications for social policy and the potential for negative social consequences. Although IRB members often raise concerns about potential long-term social implications in protocol review, federal regulations strongly discourage IRBs from (...) considering them in their decisions. Yet IRBs often do consider the social implications of research protocols and sometimes create significant delays in initiating or even prevent such research. The social implications of research are important topics for public scrutiny and professional discussion. This article examines the reasons that the federal regulations preclude IRBs from assessing the social risks of research, and examines alternative approaches that have been used with varying success by national advisory groups to provide such guidance. The article concludes with recommendations for characteristics of a national advisory group that could successfully fulfill this need, including sustainability, independence, diverse and relevant expertise, and public transparency.

: In light of information uncovered about human radiation experiments conducted during the Cold War, an important charge for the Advisory Committee on Human Radiation Experiments was to assess the current state of protections for human research subjects. This assessment was designed to enhance the Committee's ability to make informed recommendations for the improvement of future policies and practices for the protection of research subjects. The Committee's examination of current protections revealed great improvement over those from the past, yet some (...) problems remain. Although the data collected by the Committee highlight specific areas in need of attention, the Committee's work should be viewed in part as the beginning of a series of ongoing assessments of the adequacy and effectiveness of the protections afforded to human subjects.

Pragmatic randomized controlled trials are designed to evaluate the effectiveness of interventions in real-world clinical conditions. However, these studies raise ethical issues for researchers and regulators. Our objective is to identify a list of key ethical issues in pragmatic RCTs and highlight gaps in the ethics literature. We conducted a scoping review of articles addressing ethical aspects of pragmatic RCTs. After applying the search strategy and eligibility criteria, 36 articles were included and reviewed using content analysis. Our review identified four (...) major themes: 1) the research-practice distinction; 2) the need for consent; 3) elements that must be disclosed in the consent process; and 4) appropriate oversight by research ethics committees. 1) Most authors reject the need for a research-practice distinction in pragmatic RCTs. They argue that the distinction rests on the presumptions that research participation offers patients less benefit and greater risk than clinical practice, but neither is true in the case of pragmatic RCTs. 2) Most authors further conclude that pragmatic RCTs may proceed without informed consent or with simplified consent procedures when risks are low and consent is infeasible. 3) Authors who endorse the need for consent assert that information need only be disclosed when research participation poses incremental risks compared to clinical practice. Authors disagree as to whether randomization must be disclosed. 4) Finally, all authors view regulatory oversight as burdensome and a practical impediment to the conduct of pragmatic RCTs, and argue that oversight procedures ought to be streamlined when risks to participants are low. The current ethical discussion is framed by the assumption that the function of research oversight is to protect participants from risk. As pragmatic RCTs commonly involve usual care interventions, the risks may be minimal. This leads many to reject the research-practice distinction and question the need for informed consent. But the function of oversight should be understood broadly as protecting the liberty and welfare interest of participants and promoting public trust in research. This understanding, we suggest, will focus discussion on questions about appropriate ethical review for pragmatic RCTs. (shrink)

Early life stress precedes alterations to neuro-immune activation, which may mediate an increased risk for stress-related psychiatric disorders, potentially through alterations of central kynurenine pathway metabolites, the latter being relatively unexplored. We hypothesized that ELS in a non-human primate model would lead to a reduction of neuroprotective and increases of neurotoxic KP metabolites. Twelve adult female bonnet macaques reared under conditions of maternal variable foraging demand were compared to 27 age- and weight-matched non-VFD-exposed female controls. Baseline behavioral observations of social (...) affiliation were taken over a 12-week period followed by the first cerebrospinal fluid sample. Subjects were then either exposed to a 12-week repeated separation paradigm or assigned to a “no-RSP” condition followed by a second CSF. We used high-performance liquid chromatography for kynurenine, tryptophan, 5-hydroxyindoleacetic acid, kynurenic acid, and anthranilic acid as a proxy for quinolinic acid determination. At baseline, social affiliation scores were reduced in VFD-reared versus control subjects. CSF log KYNA and log KYNA/KYN ratio were lower in VFD-reared versus control subjects. CSF log KYNA/KYN was positively correlated with CSF log ANTH in VFD only. Controlling for log KYNA/KYN, log ANTH was elevated in VFD-reared subjects versus controls. CSF log KYNA/KYN obtained post-RSP was positively correlated with mean social affiliation scores during RSP, specifically in VFD. ELS is associated with a reduced neuroprotective and increased neurotoxic pathway products. That the two contrasting processes are paradoxically correlated following ELS suggests a cross-talk between two opposing KP enzymatic systems. (shrink)

Recent legislation, such as the Patient Self-Determination Act, establishes advance directives as an acceptable procedural means of incorporating patients’ preferences for life-sustaining treatments into their medical care. Advance directives can enhance medical decision making since they provide patients with an opportunity to communicate their preferences before suffering from an acute illness that may preclude their ability to do so.Although patients expect discussions about life-sustaining therapies to be initiated by their physicians, very little is known about what prompts physicians to discuss (...) advance directives with their patients. As in other areas of clinical decision making, there is evidence that patients’ sociodemographic factors influence whether discussions about advance directives occur between patients and their physicians. In one study of persons with the acquired immunodeficiency syndrome, those who had not had discussions about advance directives with their physicians tended to be non-white, have no prior hospitalization, and were more likely to have been cared for in a health maintenance organization than in a teaching hospital.

A challenge of performing research in the paediatric emergency and acute care setting is obtaining valid prospective informed consent from parents. The ethical issues are complex, and it is important to consider the perspective of participants, health care workers and researchers on research without prospective informed consent while planning this type of research. We performed a systematic review according to PRISMA guidelines, of empirical evidence relating to the process, experiences and acceptability of alternatives to prospective informed consent, in the paediatric (...) emergency or acute care setting. Major medical databases and grey sources were searched and results were screened and assessed against eligibility criteria by 2 authors, and full text articles of relevant studies obtained. Data were extracted onto data collection forms and imported into data management software for analysis. Thirteen studies were included in the review consisting of nine full text articles and four abstracts. Given the heterogeneity of the methods, results could not be quantitatively combined for meta-analysis, and qualitative results are presented in narrative form, according to themes identified from the data. Major themes include capacity of parents to provide informed consent, feasibility of informed consent, support for alternatives to informed consent, process issues, modified consent process, child death, and community consultation. Our review demonstrated that children, their families, and health care staff recognise the requirement for research without prior consent, and are generally supportive of enrolling children in such research with the provisions of limiting risk, and informing parents as soon as possible. Australian data and perspectives of children are lacking and represent important knowledge gaps. (shrink)

Quality and service improvement (QSI) research employs a broad range of methods to enhance the efficiency of healthcare delivery. QSI research differs from traditional healthcare research and poses unique ethical questions. Since QSI research aims to generate knowledge to enhance quality improvement efforts, should it be considered research for regulatory purposes? Is review by a research ethics committee required? Should healthcare providers be considered research participants? If participation in QSI research entails no more than minimal risk, is consent required? The (...) lack of consensus on answers to these questions highlights the need for ethical guidance. Three distinct approaches to classifying QSI research in accordance with existing ethical principles and regulations can be found in the literature. In the first approach, QSI research is viewed as distinct from other types of healthcare research and does not require regulation. In the second approach, QSI research falls within regulatory guidelines but is exempt from research ethics committee review. In the third approach, QSI research is deemed to be part of the learning healthcare system and, as such, is subject to a different set of ethical principles entirely. In this paper, we critically assess each of these views. While none of these approaches is entirely satisfactory, we argue that use of the ethical principles governing research provides the best means of addressing the numerous questions posed by QSI research.

The early twentieth century was a lively time for the foundations of mathematics. This ensuing debates were, in large part, a reaction to the settheoretic and nonconstructive methods that had begun making their way into mathematical practice around the turn of the twentieth century. The controversy was exacerbated by the discovery that overly na¨ıve formulations of the fundamental principles governing the use of sets could result in contradictions. Many of the leading mathematicians of the day, including Hilbert, Henri Poincar´e, ´.

Jeremy Bentham was an ardent secularist convinced that society could be sustained without the support of religious institutions or beliefs. This is writ large in the commonly neglected books on religion he wrote and published during the last twenty-five years of his life. However his earliest writings on the subject date from the 1770s, when as a young man he first embarked on his calling as a legal theorist and social reformer. From that time on, religion was never far (...) from the centre of his thoughts. In Secular Utilitarianism, James Crimmins illustrates the nature, extent, and depth of Jeremy Bentham's concern with religion, from his Oxford days of first doubts to the middle years of quiet unbelief, and finally, the zealous atheism and secularism of his later life. Dr Crimmins provides an interpretation of Bentham's thought in which his religious views, hitherto of little interest to Bentham scholars, are shown to be integral: on the one hand intimately associated with the metaphysical, epistemological, and psychological principles which gave shape to his system as a whole, and on the other central to the development of his entirely secular view of society.

Over the past decade, there has been an extensive debate about whether researchers have an obligation to disclose genetic research findings, including primary and secondary findings. There appears to be an emerging (but disputed) view that researchers have some obligation to disclose some genetic findings to some research participants. The contours of this obligation, however, remain unclear. -/- As this paper will explore, much of this confusion is definitional or conceptual in nature. The extent of a researcher’s obligation to return (...) secondary and other research findings is often limited by reference to terms and concepts like “incidental,” “analytic validity,” “clinical validity,” “clinical relevance,” “clinical utility,” “clinical significance,” “actionability,” and “desirability.” These terms are used in different ways by different writers to describe obligations in different sorts of cases. -/- Underneath this definitional confusion is a general notion, supported by much of the literature, that findings only need to be disclosed when they surpass certain presumably objective or measureable thresholds, such as medical importance or scientific reproducibility. The problem is that there is significant variability in the way that these terms and concepts are used in the literature and, as such, in defining the scope of an obligation to return findings that surpasses the relevant thresholds. -/- The goal of this paper is to analyze the definitional muddle underlying the debate about returning genetic research findings, with the hope of answering a few questions. First, what is the range of definitions being used in this debate? Based on an extensive literature review, Part 1 will lay out a range of articulated definitions for each relevant term, with the goal of categorizing them into a handful of distinct types. Part 2 explains the definitional redundancy and confusion in the current literature, and, drawing from the terminological patterns identified in Part 1, outlines more cohesive building blocks to inform the development of future disclosure frameworks.Our minimum goal in articulating these conceptual building blocks is to promote clearer articulations of, and distinctions between, future disclosure frameworks. More ambitiously, we suggest which definitions and conceptualizations we consider most appropriate to use in future disclosure frameworks. Here, we seek to balance benefits to participants through the disclosure of important information with the minimization of undue burdens on individual researchers and the research enterprise more generally. -/- Our analysis builds upon the central philosophical distinction between concepts and conceptions. The basic idea is that the “concept” of X refers to the general (and relatively uncontroversial) structure/shape of X, while various “conceptions” of X are more particular, filled out, and controversial elaborations of the concept. In other words, “concepts” of X will be formal representations of X, while “conceptions” of X will be substantive interpretations of the key elements and relationships operating within that formal framework. (Implicit in this distinction is an important point about the nature of disagreement – namely, that in order for two or more parties to “disagree” about X as opposed to simply talk past one another, there must be at least enough shared agreement about X to know that the parties are referring to the same thing. A concept of X provides this point of common agreement, while competing conceptions of X mark the areas where disagreement arises.) In this paper, we will employ this distinction in a fundamental way to clarify exactly where the primary disagreements arise in the debate over disclosing genetic research findings. -/- We propose that, underlying all the seeming confusion and disagreement, there are three central and widely agreed upon concepts at work in this debate—validity, value, and volition. The first two concepts concern the nature of the information itself. An obligation to disclose only exists when findings are valid and have value but there are competing conceptions of how to determine or define validity and valuableness. The third concept—volition—pertains not to the information but rather to the person to whom it will be disclosed. Does that person want or not want the information, and what is the best way of determining this? Here, too, competing conceptions arise. Our key point, though, is that almost all of the ethical disagreement arises because of competing conceptions of these three concepts. Understanding and appreciating this key point can help to refocus the substantive debate by providing some common ground to start from in determining how best to interpret these shared concepts. This refocusing can, ideally, produce more productive debate and facilitate some progress in resolving it. (shrink)

Participants in clinical research sometimes view participation as therapy or exaggerate potential benefits, especially in phase I or phase II trials. We conducted this study to discover what methods might improve cancer patients’ understanding of early-phase clinical trials. We randomly assigned 130 cancer patients from three U.S. medical centers who were considering enrollment in a phase I or phase II cancer trial to receive either a multimedia intervention or a National Cancer Institute pamphlet explaining the trial and its purpose. Intervention (...) participants were 32 times more likely to believe that the trial’s purpose was to examine safety and 60 % less likely to believe they would experience long-term benefit or cure. There was no difference in enrollment decision. However, while patients’ understanding of the trial’s purpose improved and expectations of long-term benefit diminished, half the respondents still believed they would experience long-term benefit or cure from participation. Therefore, we conclude that multimedia interventions such as this one may help oncologists to explain the risks and benefits of early-phase cancer trials in a way that patients can more easily understand, helping them to make more informed decisions about participation. But further research into other factors that influence patients’ beliefs about the outcome of enrollment is needed, both to modify the interventions and to determine how malleable patient beliefs are.

The lives of few mathematicians offer the drama that is presented by the life of L. E. J. Brouwer, correctly identified on the cover of this book as a topologist, intuitionist, and philosopher, and before we go any further, it will be worth indicating why.It is not just that Brouwer would rank high among mathematicians for his work in topology alone: he set standards for rigour and created a theory of dimension for topological spaces, and his fixed-point theorem is of (...) great importance. Nor is it just that his philosophy of intuitionism created a new and vibrant branch of logic, that is, arguably, the only viable alternative to naïve, classical logic outside the enclave of professional logicians. Rather, it is that there is a tension, popularly taken to amount to a contradiction, in the fundamental ideas behind his topology and his intuitionism. Added to that, he took a highly principled stand on mathematical issues that led him into confrontations with major figures and a certain degre .. (shrink)
