Στην περιγραφή του ιερού των Δελφών, ο Παυσανίας αποδίδει μια ξεχωριστή θέση στην ερμηνεία των αναθημάτων που είχαν στηθεί στο δελφικό ιερό. Μερικά παραδείγματα είναι αρκετά για να φανεί το ενδιαφέρον των σχολίων που μας άφησε ο Περιηγητής, αλλά και η δυσκολία που αντιμετωπίζουμε στο διαχωρισμό ανάμεσα στην πραγματικότητα και τη φαντασία που εμπεριέχονται στα σχόλια αυτά.

Humanitarian health care practitioners working outside familiar settings, and without familiar supports, encounter ethical challenges both familiar and distinct. The ethical guidance they rely upon ought to reflect this. Using data from empirical studies, we explore the strengths and weaknesses of two ethical models that could serve as resources for understanding ethical challenges in humanitarian health care: clinical ethics and public health ethics. The qualitative interviews demonstrate the degree to which traditional teaching and values of clinical health ethics seem insufficient (...) for addressing all the realities of health care practice during humanitarian missions. They equally suggest that greater good orientations of public health ethics can thwart the best intentions of health care professionals wanting to attend to the interests of individual patients. Even though neither is complete on its own for helping guide health professionals on field missions, taken together these models have much to offer. At the same time, the narratives of the humanitarian health care workers illustrate how some of the crucial differences between public health ethics and clinical ethics generate tensions in humanitarian health practice. We offer an analysis of some of the complexities this creates for humanitarian health care ethics, and consider ways of adjudicating between the two models. (shrink)

We investigate how to assign probabilities to sentences that contain a type-free truth predicate. These probability values track how often a sentence is satisfied in transfinite revision sequences, following Gupta and Belnap’s revision theory of truth. This answers an open problem by Leitgeb which asks how one might describe transfinite stages of the revision sequence using such probability functions. We offer a general construction, and explore additional constraints that lead to desirable properties of the resulting probability function. One such property (...) is Leitgeb’s Probabilistic Convention T, which says that the probability of φ equals the probability that φ is true. (shrink)

The interactivist approach to development generates a framework of types of constraints on what can be constructed. The four constraint types are based on: (1) what the constructed systems are about; (2) the representational relationship itself; (3) the nature of the systems being constructed; and (4) the process of construction itself. We give illustrations of each constraint type. Any developmental theory needs to acknowledge all four types of constraint; however, some current theories conflate different types of constraint, or rely on (...) a single constraint type to explicate development. Such theories will be inherently unable to explain important aspects of development. (shrink)

Taking Rom Harré's social constructionism as a focus we point to and discuss the issue of the a priori psychological subject in social constructionist theory. While Harré indicates that interacting, intending beings are necessary for conversation to occur, he assumes that the primary human reality is conversation and that psychological life emerges from this social domain. Nevertheless, we argue that a fundamental and agentive psychological subject is implicit to his constructionist works. Our critical analyses focus upon Harré's understandings of persons, (...) human development and human agency. Our intention is neither to suggest that this latent entity must be understood in a Cartesian sense nor is it to ask for an explicit accounting of an autonomous agent. Rather, our claim is simply that psychological subjectivity is reflexively entailed in Harré's human psychology. We suggest that this pertains more generally to social constructionist theory.

Marine ecosystems are under increasing pressure from human activity, yet successful management relies on knowledge. The evidence-based policy (EBP) approach has been promoted on the grounds that it provides greater transparency and consistency by relying on ‘high quality’ information. However, EBP also creates epistemic responsibilities. Decision-making where limited or no empirical evidence exists, such as is often the case in marine systems, creates epistemic obligations for new information acquisition. We argue that philosophical approaches can inform the science-policy interface. Using marine (...) biosecurity examples, we specifically examine the epistemic challenges in the acquisition and acceptance of evidence to inform policy, discussing epistemic due care and biases in consideration of evidence.

It is often argued that the indispensability of continuum models comes from their empirical adequacy despite their decoupling from the microscopic details of the modelled physical system. There is thus a commonly held misconception that temperature varying across a region of space or time can always be accurately represented as a continuous function. We discuss three inter-related cases of temperature modelling — in phase transitions, thermal boundary resistance and slip flows — and show that the continuum view is fallacious on (...) the ground that the microscopic details of a physical system are not necessarily decoupled from continuum models. We show how temperature discontinuities are present in both data (experiments and simulations) and phenomena (theory and models) and how discontinuum models of temperature variation may have greater empirical adequacy and explanatory power. The conclusions of our paper are: a) continuum idealisations are not indispensable to modelling physical phenomena and both continuous and discontinuous representations of phenomena work depending on the context; b) temperature is not necessarily a continuously defined function in our best scientific representations of the world; and c) that its continuity, where applicable, is a contingent matter. We also raise a question as to whether discontinuous representations should be considered truly de-idealised descriptions of physical phenomena. (shrink)

Every word signifies multiple senses. Many studies using comprehension-based measures suggest that polysemes’ senses share lexical representations, whereas homophones’ meanings correspond to distinct lexical representations. Less is known about the lexical representations of polysemes compared to homophones in language production. In this study, speakers named pictures after reading sentence fragments that primed polysemes and homophones either as direct competitors to pictures, or as indirect-competitors to pictures. Polysemes elicited equal numbers of intrusions to picture names compared to in control conditions whether (...) primed as direct competitors or as indirect-competitors. This contrasted with the finding that homophones elicited more intrusions to picture names compared to in control conditions when primed as direct competitors than when primed as indirect-competitors. These results suggest that polysemes, unlike homophones, are stored and retrieved as unified lexical representations. (shrink)

Background Informed consent is an integral component of good medical practice. Many researchers have investigated measures to improve the quality of informed consent, but it is not clear which techniques work best and why. To address this problem, we propose developing a core outcome set to evaluate interventions designed to improve the consent process for surgery in adult patients with capacity. Part of this process involves reviewing existing research that has reported what is important to patients and doctors in the (...) informed consent process. Methods This qualitative synthesis comprises four phases: identification of published papers and determining their relevance; appraisal of the quality of the papers; identification and summary of the key findings from each paper while determining the definitiveness of each finding against the primary data; comparison of key themes between papers such that findings are linked across studies. Results Searches of bibliographic databases returned 11,073 titles. Of these, 16 studies met the inclusion criteria. Studies were published between 1996 and 2016 and included a total of 367 patients and 74 health care providers. Thirteen studies collected data using in-depth interviews and constant comparison was the most common means of qualitative analysis. A total of 94 findings were extracted from the primary papers and divided into 17 categories and ultimately 6 synthesised findings related to: patient characteristics, knowledge, communication, the model patient, trust and decision making. Conclusions This qualitative meta-aggregation is the first to examine the issue of informed consent for surgery. It has revealed several outcomes deemed important to capture by patients and clinicians when evaluating the quality of a consent process. Some of these outcomes have not been examined previously in research comparing methods for informed consent. This review is an important step in the development of a COS to evaluate interventions designed to improve the consent process for surgery. Registration The study protocol was registered on the international prospective register for systematic reviews. (shrink)

There is a major debate as to whether there are non-causal mathematical explanations of physical facts that show how the facts under question arise from a degree of mathematical necessity considered stronger than that of contingent causal laws. We focus on Marc Lange’s account of distinctively mathematical explanations to argue that purported mathematical explanations are essentially causal explanations in disguise and are no different from ordinary applications of mathematics. This is because these explanations work not by appealing to what the (...) world must be like as a matter of mathematical necessity but by appealing to various contingent causal facts. (shrink)

So-called ‘distinctively mathematical explanations’ (DMEs) are said to explain physical phenomena, not in terms of contingent causal laws, but rather in terms of mathematical necessities that constrain the physical system in question. Lange argues that the existence of four or more equilibrium positions of any double pendulum has a DME. Here we refute both Lange’s claim itself and a strengthened and extended version of the claim that would pertain to any n-tuple pendulum system on the ground that such explanations are (...) actually causal explanations in disguise and their associated modal conditionals are not general enough to explain the said features of such dynamical systems. We argue and show that if circumscribing the antecedent for a necessarily true conditional in such explanations involves making a causal analysis of the problem, then the resulting explanation is not distinctively mathematical or non-causal. Our argument generalises to other dynamical systems that may have purported DMEs analogous to the one proposed by Lange, and even to some other counterfactual accounts of non-causal explanation given by Reutlinger and Rice.

How We Know is intended as a summary of Objectivist epistemology. Binswanger's treatment of a wide range of epistemological issues is examined. Because his theory of propositions is inadequate and his philosophy of mind is an extreme form of dualism, Binswanger has added little to previous efforts by “official” Objectivists. As a work of epistemology in the broad sense, Binswanger's effort is fatally impaired. It is undone by his bifurcation between consciousness and the physics of the brain, which, if accepted, (...) would largely deprive psychology and even computer science of their subject matter.

As infancy is characterized by rapid physical growth and critical periods of development, disruptions due to illness or disease reveal vulnerability associated with this period. Spinal cord injury has devastating consequences at any age, but its onset neonatally, at birth, or within the first year of life multiplies its impact. The immediate physical and physiological consequences are obvious and immense, but the effects on the typical trajectory of development are profound. Activity-based restorative therapies capitalize on activity-dependent plasticity of the neuromuscular (...) system below the lesion and when provided to children with SCI aim to improve the child’s neuromuscular capacity, health and quality of life. This is a report of an infant with a cervical SCI at birth resulting in paralysis of leg and trunk muscles and paresis of arm and hands who was enrolled in an ABRT program at 3 years of age. After 59 sessions of ABRT, the child demonstrated significant improvements in trunk control and arm function, as well as social and emotional development. Despite the chronicity of injury and low expectations for improvement with therapeutic interventions, ABRT had a positive impact on the child’s physical capacity and provided benefits across multiple developmental domains.

The prohibition against psychologizing has been a source of confusion to many Randians. Psychologizing is the practice of incorrectly or improperly inferring motives in other people instead of rendering moral judgment. Rand thought that it could manifest in two ways: inquisitorial and excuse-making. However, Rand's concrete examples are preponderantly of the excuse-making type; her bright line between psychology and philosophy is unsuccessfully drawn; and in offering extended, strongly condemnatory analyses of the supposed motives behind psychologizing, she yields to the very (...) temptation she claims to warn against. “Psychologizing” turns out to be an anticoncept.

This article explores the accounts of Canadian-trained health professionals working in humanitarian and development organizations who considered not treating a patient or group of patients because of resource limitations. In the narratives, not treating the patient(s) was sometimes understood as the right thing to do, and sometimes as wrong. In analyzing participants’ narratives we draw attention to how medications and equipment are represented. In one type of narrative, medications and equipment are represented primarily as scarce resources; in another, they are (...) represented as patient care. In the contexts respondents were working, medications and equipment were often both patient care interventions and scarce resources. The analytic point is that health professionals tend to emphasize one conceptualization over the other in coming to assert that not treating is right, or wrong. Rendering tacit ethical frameworks more explicit makes them available for reflection and debate. (shrink)

Two complementary biographies of Ayn Rand were published in 2009: Goddess of the Market, by Jennifer Burns, and Ayn Rand and the World She Made, by Anne Heller. Burns focuses on Rand's influence on American political thought, while Heller's concern is Rand the screenwriter, novelist, and author of her personal mythos. Both books are meticulously researched and well written; neither author espouses Rand's philosophy or agrees with her politics. Such books establish that Rand's ideas have become part of American culture (...) and are no longer set over and against it. (shrink)

Leonard Peikoff brought into Objectivist epistemology the doctrine that what is asserted arbitrarily cannot be true or false. In 2008 the author gave a detailed critique of the doctrine; it has not received a published response. But there have been restatements by Harry Binswanger, Ben Bayer, and Gregory Salmieri. Their re-presentations do not refute any old arguments; their new arguments make the doctrine worse. The doctrine is being used to justify ignoring known possibilities, and to “prove” that the current president (...) of the United States has a parrot's mind in a human body. Its public retraction is overdue. (shrink)

Think as If Your Life Depends on It puts Barbara Branden’s lectures on the Principles of Efficient Thinking in print at last, along with three later lectures. In Roger Bissell’s excellent transcription, the ten lectures introduce readers to psycho-epistemology, the difference between directed and undirected thinking, the role of the subconscious in problem-solving, common faults in thinking, and motivational issues that interfere with thinking. Her contributions were effectively erased from Objectivism after the Nathaniel Branden Institute closed; the original lectures were (...) the most significant part of the Objectivist corpus that remained to be recovered.
