This article is detective work, not philosophy. J. S. Mill's Autobiography records that at the age of seven he read, in Greek, ‘the first six dialogues of Plato, from the Euthyphron to the Theaetetus inclusive’. Which were the other dialogues? On the arrangement common today, it would be Crito, Apology, Phaedo, Cratylus. On the arrangement common then, Theages and Erastai replace Cratylus, which makes seven dialogues. I show that this must be the answer by the evidence of James Mill's commonplace (...) books and his writings on Plato. These reveal which collected edition of Plato he owned and which he would want to own. Conditions for studying Plato in the original were much harder than we are used to. The inquiry highlights both the ideological purity of the education James Mill designed for his son, and the difficulties he faced in realizing his plan. (shrink)

In Intricate Ethics, Kamm questions the moral importance of some non-consequentialist distinctions and then introduces and argues for the moral importance of other distinctions. The first section discusses nonconsequentialist ethical theory and the trolley problem; the second deals with the notions of moral status and rights; the third takes up the issues of responsibility and complicity and the possible moral significance of distance; and the fourth section analyzes the views of others in the non-consequentialist and consequentialist camps.

Context: The dominant approach to the study of perception is representational/computational, with an emphasis on the achievements of the brain and the nervous system, which are taken to construct internal models of the world. Alternatives include ecological, embedded, embodied, and enactivist approaches, all of which emphasize the centrality of action in understanding perception. Problem: Despite sharing many theoretical commitments that lead to a rejection of the classical approach, the alternatives are characterized by important contrasts and points of divergence. Here we (...) focus on the enactive and ecological approaches, in particular, on how they construe the status of the environment and the content of perception. Method: We begin with a review of James Gibson’s ecological psychology, highlighting it as a psychology for all organisms not just humans. Against this backdrop, we consider enactivist arguments against direct perception - a central assertion of the ecological approach - and in favor of interpreting the activity of perceptual agents as a kind of construction of a perceptually meaningful world. Results: We assess the merits of this interpretation and we conclude that it cannot be grounded on fundamental principles such as thermodynamics and organism-environment mutuality. Implications: As a consequence, enactivism remains close to representationalism and entails a form of dualism. Constructivist content: We advance a criticism of the constructivist foundations of the enactive approach to perception. Perception-action mutuality at the heart of enactivism does not require mental construction; indeed, perception-action mutuality obviates construction. (shrink)

This essay argues that the Putnam-Nussbaum thesis that modern functionalism is Aristotelian is false. It fails as an interpretation of Aristotle since it fails to notice that Aristotle’s conception of the material or physical side of the soul-body relation is one which no modern functionalist could share. The Putnam-Nussbaum thesis is examined within the context of the theory of perception. This involves the need to understand one of the most mysterious Aristotelian doctrines – the doctrine that in perception, the sense-organ (...) assumes the sensible form of the object perceived without its matter.

In this paper two models for movement of respiratory gases in the insect trachea are presented. One model considers the tracheal system as a single flexible compartment while the other model considers the trachea as a single flexible compartment with gas exchange. This work represents an extension of Ben-Tal’s work on compartmental gas exchange in human lungs and is applied to the insect tracheal system. The purpose of the work is to study nonlinear phenomena seen in the insect respiratory system. (...) It is assumed that the flow inside the trachea is laminar, and that the air inside the chamber behaves as an ideal gas. Further, with the isothermal assumption, the expressions for the tracheal partial pressures of oxygen and carbon dioxide, rate of volume change, and the rates of change of oxygen concentration and carbon dioxide concentration are derived. The effects of some flow parameters such as diffusion capacities, reaction rates and air concentrations on net flow are studied. Numerical simulations of the tracheal flow characteristics are performed. The models developed provide a mathematical framework to further investigate gas exchange in insects. (shrink)

Feature selection is a widely studied technique whose goal is to reduce the dimensionality of the problem by removing irrelevant features. It has multiple benefits, such as improved efficacy, efficiency and interpretability of almost any type of machine learning model. Feature selection techniques may be divided into three main categories, depending on the process used to remove the features known as Filter, Wrapper and Embedded. Embedded methods are usually the preferred feature selection method that efficiently obtains a selection of the (...) most relevant features of the model. However, not all models support an embedded feature selection that forces the use of a different method, reducing the efficiency and reliability of the selection. Neural networks are an example of a model that does not support embedded feature selection. As neural networks have shown to provide remarkable results in multiple scenarios such as classification and regression, sometimes in an ensemble with a model that includes an embedded feature selection, we attempt to embed a feature selection process with a general-purpose methodology. In this work, we propose a novel general-purpose layer for neural networks that removes the influence of irrelevant features. The Feature-Aware Drop Layer is included at the top of the neural network and trained during the backpropagation process without any additional parameters. Our methodology is tested with 17 datasets for classification and regression tasks, including data from different fields such as Health, Economic and Environment, among others. The results show remarkable improvements compared to three different feature selection approaches, with reliable, efficient and effective results. (shrink)

It is a standing temptation for philosophers to find anticipations of their own views in the great thinkers of the past, but few have been so bold in the search for precursors, and so utterly mistaken, as Berkeley when he claimed Plato and Aristotle as allies to his immaterialist idealism. InSiris: A Chain of Philosophical Reflexions and Inquiries Concerning the Virtues of Tar-Water, which Berkeley published in his old age in 1744, he reviews the leading philosophies of antiquity and finds (...) them on the whole a good deal more sympathetic to his own ideas than the ‘modern atheism’, as he calls it, of Hobbes and Spinoza or the objectionable principles of ‘the mechanic and geometrical philosophers’ such as Newton. But his strongest and, I think, his most interesting claim is that neither Plato nor Aristotle admitted ‘an absolute actual existence of sensible or corporeal things’. (shrink)

Why is death bad for us, even on the assumption that it involves the absence of experience? Is it worse for us than prenatal nonexistence? In this first volume of the two-volume Morality, Mortality, Kamm begins by considering these questions, critically examining some answers other philosophers have given. The book examines specifically what differences between persons are relevant to the distribution of any scarce resource, discussing for example, the distribution of bodily organs for transplantation.

There is general acknowledgement that both the anterior cingulate and orbitofrontal cortex are implicated in reinforcement-guided decision making, and emotion and social behaviour. Despite the interest that these areas generate in both the cognitive neuroscience laboratory and the psychiatric clinic, ideas about the distinctive contributions made by each have only recently begun to emerge. This reflects an increasing understanding of the component processes that underlie reinforcement- guided decision making, such as the representation of reinforcement expectations, the exploration, updating and representation (...) of action values, and the appreciation that choices are guided not just by the prospect of reward but also by the costs that action entails. Evidence is emerging to suggest that the anterior cingulate and orbitofrontal cortex make distinct contributions to each of these aspects of decision making. (shrink)

Background: Informed consent is regarded as a contract between autonomous and equal parties and requires the elements of information disclosure, understanding, voluntariness and consent. The validity of informed consent for critically ill patients has been questioned. Little is known about how these patients experience the process of consent.Objective: The aim of this study was to explore critically ill patients’ experience with the principle of informed consent in a clinical trial and their ability to give valid informed consent.Design: 11 stroke patients (...) who had been informed about thrombolytic treatment and had been through the process of deciding whether or not to participate in a thrombolysis trial went through repeated qualitative semistructured interviews.Results: None of the patients had any clear understanding of the purpose of the trial. Neither did they understand the principles of randomisation and voluntariness. Reasons for giving or not giving consent were trust, conceptions of benefits and risks and altruism. Several patients found it immoral to involve patients in the consent procedure and argued that this was the doctors’ responsibility. Others argued that it is a duty to question patients and perceived it as a sign of being treated with respect and dignity. A majority of the patients found the consent process vague and ambiguous.Conclusions: The results indicate that the principle of informed consent from critically ill patients cannot be seen as a contract between equal and autonomous parties. Further studies are needed to explore critically ill patients’ experiences with the process of informed consent. (shrink)

M. F. Burnyeat taught for 14 years in the Philosophy Department of University College London, then for 18 years in the Classics Faculty at Cambridge, 12 of them as the Laurence Professor of Ancient Philosophy, before migrating to Oxford in 1996 to become a Senior Research Fellow in Philosophy at All Souls College. The studies, articles and reviews collected in these two volumes of Explorations in Ancient and Modern Philosophy were all written, and all but two published, before that decisive (...) change. Whether designed for a scholarly audience or for a wider public, they range from the Presocratics to Augustine, from Descartes and Bishop Berkeley to Wittgenstein and G. E. Moore. Their subject-matter falls under four main headings: 'Logic and Dialectic' and 'Scepticism Ancient and Modern', which are contained in this first volume; 'Knowledge' and 'Philosophy and the Good Life' make up the second volume. The title 'Explorations' well expresses Burnyeat's ability to discover new aspects of familiar texts, new ways of solving old problems. In his hands the history of philosophy becomes itself a philosophical activity. (shrink)

Background: The factors influencing parents’ willingness to enroll their children in biobanks are poorly understood. This study sought to assess parents’ willingness to enroll their children, and their perceived benefits, concerns, and information needs under different consent and data-sharing scenarios, and to identify factors associated with willingness. Methods: This large, experimental survey of patients at the 11 eMERGE Network sites used a disproportionate stratified sampling scheme to enrich the sample with historically underrepresented groups. Participants were randomized to receive one of (...) three consent and data-sharing scenarios. Results: In total, 90,000 surveys were mailed and 13,000 individuals responded (15.8% response rate). 5737 respondents were parents of minor children. Overall, 55% (95% confidence interval 50–59%) of parents were willing to enroll their youngest minor child in a hypothetical biobank; willingness did not differ between consent and data-sharing scenarios. Lower educational attainment, higher religiosity, lower trust, worries about privacy, and attitudes about benefits, concerns, and information needs were independently associated with less willingness to allow their child to participate. Of parents who were willing to participate themselves, 25% were not willing to allow their child to participate. Being willing to participate but not willing to allow one’s child to participate was independently associated with multiple factors, including race, lower educational attainment, lower annual household income, public health care insurance, and higher religiosity. Conclusions: Fifty-five percent of parents were willing to allow their youngest minor child to participate in a hypothetical biobank. Building trust, protecting privacy, and addressing attitudes may increase enrollment and diversity in pediatric biobanks. (shrink)

Theaetetus, asked what knowledge is, replies that geometry and the other mathematical disciplines are knowledge, and so are crafts like cobbling. Socrates points out that it does not help him to be told how many kinds of knowledge there are when his problem is to know what knowledge itself is, what it means to call geometry or a craft knowledge in the first place—he insists on the generality of his question in the way he often does when his interlocutor, asked (...) for a definition, cites instead cases of the concept to be defined.
