The term research subject has traditionally been the preferred term in professional guidelines and academic literature to describe a patient or an individual taking part in biomedical research. In recent years, however, there has been a steady shift away from the use of the term 'research subject' in favour of 'research participant' when referring to individuals who take part by providing data to various kinds of biomedical and epidemiological research. This article critically examines this shift, reflecting on the different meanings (...) evoked by the terms 'subject' and 'participant', as well as examining recent examples of patient activism in research. It concludes by suggesting that the wholesale unreflective adoption of the term 'participant' is inappropriate and provides instead a guide on how to determine the circumstances in which the terms subject, participant and activist should legitimately be used.

Este artículo trabaja la presencia plotiniana en la Edad Media y el Renacimiento. En primer término, se presenta el movimiento de transmisión indirecta de las Enéadas a lo largo de la Edad Media y las ediciones que resurgen en el Renacimiento. En esta línea, se discute precisamente la presencia e influencia de las ideas plotinianas en pensadores medievales. En segundo término, se despliegan ciertas notas nucleares del pensamiento de Plotino –las tres hipóstasis y un solo universo– para luego, en tercer (...) término, exponer las profundas coincidencias que pueden encontrarse en la estructura del pensamiento de Nicolás de Cusa –con el estudio del lenguaje de los binomios complicación-explicación, incontracto-contracto. Finalmente, se considera la posibilidad de incluir a ambos autores en una Gran Teoría Unificada que se despliega a lo largo de la Edad Media. (shrink)

A review of the literature indicates that linear models are frequently used in situations in which decisions are made on the basis of multiple codable inputs. These models are sometimes used normatively to aid the decision maker, as a contrast with the decision maker in the clinical vs statistical controversy, to represent the decision maker "paramorphically" and to "bootstrap" the decision maker by replacing him with his representation. Examination of the contexts in which linear models have been successfully employed indicates (...) that the contexts have the following structural characteristics in common: each input variable has a conditionally monotone relationship with the output; there is error of measurement; and deviations from optimal weighting do not make much practical difference. These characteristics ensure the success of linear models, which are so appropriate in such contexts that random linear models may perform quite well. 4 examples involving the prediction of such codable output variables as GPA and psychiatric diagnosis are analyzed in detail. In all 4 examples, random linear models yield predictions that are superior to those of human judges. (shrink)

This book tells a compelling story about love, friendship, and the Divine that took over a thousand years to unfold. It argues that mind and feeling are intrinsically connected in the thought of Plato, Aristotle, and Plotinus; that Aristotle developed his theology and physics primarily from Plato’s Symposium (from the “Greater” and “Lesser Mysteries” of Diotima-Socrates’ speech); and that the Beautiful and the Good are not coincident classes, but irreducible Forms, and the loving ascent of the Symposium must be interpreted (...) in the light of the Republic, as the later tradition up to Ficino saw. Against the view that Platonism is an escape from the ambiguities of ordinary experience or opposed to loving individuals for their own sakes, this book argues that Plato dramatizes the ambiguities of ordinary experience, confronts the possibility of failure, and bequeaths erotic models for the loving of individuals to later thought. Finally, it examines the Platonic-Aristotelian heritage on the Divine to discover whether God can love us back, and situates the dramatic development of this legacy in Plotinus, Iamblichus, Proclus, and Dionysius the Areopagite.

This article argues that Ralph Waldo Emerson employs metempsychosis (reincarnation or the transmigration of the soul into successive bodies) as a figurative template for human consciousness. Mapping various traditions from Hinduism, Pythagoreanism, Platonism, and Neoplatonism onto the vastness of the geological and biological records, Emerson translates metaphysics for modernity: he depicts the soul's journey through the chronological sequence of history as a poetic process that culminates in a tenuous form of self-knowledge.

In this paper I describe a novel application of contemplative techniques to software engineering with the goal of augmenting the intellectual capabilities of knowledge workers within the field in four areas: flexibility, attention, creativity, and trust. The augmentation of software engineers’ intellectual capabilities is proposed as a third complement to the traditional focus of methodologies on the process and environmental factors of the software development endeavor. I argue that these capabilities have been shown to be open to improvement through the (...) practices traditionally used in spiritual traditions, but now used increasingly in other fields of knowledge work, such as in the medical profession and the education field. Historically, the intellectual capabilities of software engineers have been treated as a given within any particular software development effort. This is argued to be an aspect ripe for inclusion within software development methodologies. (shrink)

This book explores the intimate connections, conflicts and discontinuities between religion and philosophy in the Platonic and Neoplatonic traditions from Antiquity to the early Medieval period. It presents a broader comparative view of Platonism by examining the strong Platonist resonances among different philosophical/religious traditions, primarily Jewish, Christian, Islamic and Hindu, and suggests many new ways of thinking about the relation between these two fields or disciplines that have in modern times become such distinct and, at times, entirely separate domains.

In lieu of an abstract, here is a brief excerpt of the content:LIGHT AND METAPHOR IN PLOTINUS AND ST. THOMAS AQUINAS KEVIN CORRIGAN St. Thomas More College University of Saskatchewan Saskatoon, Saskatchewan I HAVE TWO CONCERNS in this paper. The first is a broad concern, related to the nature of metaphor, which stems from the destructionist or deconstructionist tendencies in some contemporary phenomenology or phenomenological existentialism. According to these views, the logocentric emphasis of the Western tradition must be shown (...) for what it really is : an attempt to erect a cover upon a fundamental absence. In Nietzsche's well known view, "truths are illusions of which one has forgotten that they are illusions; worn-out metaphors which have become powerless to affect the senses, coins which have their obverse effaced and now are no longer of account as coins but merely as metal." 1 For Jacques Derrida all metaphoricity is caught up in an endless circle, which precludes any privileged vantage-point from which one might determine order, hierarchy and center-point. In particular, the unique heliotropic metaphor which, in Derrida's polemic, determines the whole course of Western philosophy " from the Platonic eidos to the Hegelian idea" 2 rests only upon the infinite absence of circularity, for the movement of transference " which turns the sun into metaphor " also inevitably "turns philosophical metaphor towards the sun." 3 1 Nietzsche, "On Truth and Falsity in their Ultramoral Sense (1873)," Works 2 (New York: Russell and Russell, 1964), p. 180. 2 J. Derrida, "White Mythology", trans. F. C. T. Moore, New Literary History 6 (1974), 1: 5-74 ["La mythologie blanche" in Rhetorique et philosophie, Poetique 5 (Paris: Editions du Seliu, 1971)], p. 55. a Ibid., p. 51. 187 188 KEVIN CORRIGAN In this paper I shall examine the thought of Plotinus and Aquinas, broadly described as idealist and realist respectively, with a view to determining whether or not this transference from the physical to the metaphysical is only an illicit, covert erasure of the material sense and a forgetting that all metaphor is self-implicating, that there is no non-metaphorical standpoint from which to grasp the order and structure of the metaphorical. My second concern is much more specific. It is, first, to compare Plotinus and Aquinas on light and metaphor-two thinkers who might be considered to be poles apart on these questions: on the one hand, Plotinus, the father of Neoplatonic emanationism with its insistence upon the primacy of divine light and the father, surely too, of the tradition of light-metaphysics in the later, mediaeval period; on the other hand, St. Thomas, staunchly realist in the Aristotelian tradition. Second, I will seek to show that this first impression of the gulf between the two thinkers is not borne out by a close textual analysis, and that their respective theories, despite the admitted significant difference in viewpoint, are in some respects very close indeed. Let us look briefly at the light-metaphysics tradition first. For Robert Grosseteste light is the source of all activity and its diffusion is not a material change or a change in place, but rather an instantaneous and substantial multiplication of itself in three dimensions.4 Thus, for the author of the De Intelligentiis light is the fundamental principle of motion and life: " Est autem prima lucis operatio in sensibilibus quad motum et vitam operatur in viventibus." 5 Since light is the noblest of corporeal things, it therefore has an intermediate place between pure form and matter, and for Grosseteste and also Bonaventure it is consequently named the forma corporeitatis, the fundamental form of body as 4 De philosophischen W erke des Robert Grosseteste, ed.

Light then is the substantial form of the physical universe.6 But how is physical light related to spiritual light?

The nature of experience cannot be truly understood unless the form of experience is first seen clearly. -/- “An Introduction to Awareness” is a philosophical journey that takes the reader into the heart of the presence of nondual reality – a reality in which the “spiritual” world and the “actual” world are not separate; in which the “physical” reality of science is a practical yet imaginative construction of causal mechanisms imposed by us upon the spontaneously creative, uncaused, manifestation of Nature (...) – a way of thinking about the world that is useful for manipulating it, yet which is not truly real. -/- This mechanistic way of seeing Reality comes at a great cost; one that we suffer from every day because we see ourselves as causal mechanisms too. We have accepted the mythology of science that asserts that we are separate from what we experience, that the forms of phenomenal existence are the serendipitous concretions of haphazard activity, and that the nature of a thing is nothing more than the mathematical expression of its statistical probabilities – that Nature has no soul. We have allowed this tool of practical reason – science – and this simplification of reality – mathematical modeling – to overwhelm the truth of our presence – this alive presence that we are. -/- This book shows another way to view the world, another way to construct your thoughts about it, in order to realize the wholeness of absolute reality, while still retaining the practical means of living that the modern world has given us. It explains how to use concepts in a way that does not endanger a truer understanding of reality and our participation in it. (shrink)

Tranquillity’s Secret Presents A New Understanding Of The World And Ourselves, And A Forgotten Meditation Technique That Protects You From Traumatic Harm. There Is A Way Of Seeing The World Different. -/- My goal in this book is two-fold: to introduce a revolutionary paradigm for understanding ourselves and the world; and to explain an ancient meditation technique that brought me to the insights upon which it is founded. This technique appears in different forms in the extant spiritual and religious traditions (...) over millennia which have used it — and in which it has been acknowledged as the most efficacious way to reach a direct experience of mind, or the most direct path to a union with God. Unfortunately, the proper way to use it has been largely lost over the last few centuries along with a clear understanding of why it was claimed to be so highly efficient. The primary reason for this loss is the mechanical materialism that frames all our scientific knowledge today. Lady Anne Conway, an English philosopher and a contemporary of René Déscartes, the French Metaphysician of the Seventeenth Century, was the first to characterize his philosophy as the “Mechanical philosophy.” It was Déscartes’ fascination with garden automata (moving statues) that he saw throughout Paris during his time, that led to his idea that the bodies of animals are nothing more than machines of varying complexity – which could be replaced by metal cogs, axles, and wheels. This very contemporary idea is in fact his legacy to humanity — along with the mind-body split that it entails — as mechanism became the standard to which Nature and all life was compared, and still is. This was the genesis of the modern reductive scientific understanding of life as discovered mechanisms made up of dead matter. -/- Although Déscartes’ philosophy was not materialism proper, as he held mind to not be material in nature, his was the most significant move to a cognitive framing of all phenomena as the result of mechanical interactions, and he went so far as placing all non-human animals into the machine-only category, because, he argued, they didn’t have minds. While a full account of Déscartes’ thought is not useful in this work, I want to use Lady Conway’s term to make a distinction between a mechanical materialism, which materialism has evolved into, and a less severe understanding that is not so destructive of the primacy of two aspects of being alive — mind and cognizance — which today are asserted to be by-products or epiphenomena of material processes in the brain by strict adherents to the mechanical philosophy. -/- This frame allows nothing but dead matter, and all that is comprised of dead matter, to be entertained as real. Anything beyond that is either ignored, or considered to be nothing more than figments of someone’s imagination — and this both limits and structures our thoughts about everything. Even those who believe they have moved on from this limiting understanding continue to be fenced in by language, which is structured by it — so that there is no escaping its limitations via a simple substitution or redefinition of concepts. Rather, it will take a truly revolutionary new paradigm and a concomitant reframing of our understanding of ourselves, this world, and reality, and how they come together in the new paradigm. I characterize the difficulty of this change as being like that of meeting an alien race and trying to work out how they see reality before communication can begin — which is very difficult to do when one’s own view is so limited. -/- I call this revolutionary paradigm Responsive Naturing. -/- Responsive Naturing replaces the current paradigm and its concomitant idea of deterministic causality which is foundational in scientific practice today. It can do this because, as you will see, it better accounts for all categories of phenomena, and thus includes all the most important human experiences, such as that of being alive, of beauty, of love, and the ultimate unity of all things. Responsive Naturing provides a sound foundation for the sciences, without the imposed limitation of mechanical materialist explanations, so that both science and spirituality can be founded upon this single common understanding of how things work. -/- This novel paradigmatic understanding of reality intrinsically applies to all dimensions of mental phenomena — be it of perceptions, sensations, or thoughts — and from the indeterminacy of quantum mechanics to the stochastic nature of most physical phenomena, to the often accidental, sometimes fortunate, but never sure, character of all human activities. This makes this new paradigm immediately productive in a practical way — it simply works, as I will show. It empowers us in ways that our disjointed and parochial schools of thought lock us out of completely, opening up new possible methods of looking at problems and finding solutions across disciplines. However, understanding the repercussions of the new paradigm upon one’s cognitive frame and the concomitant structure of language is difficult to comprehend simply because it is alien to the existing frame and paradigm. The impetus to make the effort is becoming quite clear: -/- Today, the sciences are ruled by the limiting cognitive framing of mechanical materialism, and over the last century, the limitations of that frame and its associated scientific paradigm of physical causality have become obvious: science has become schizophrenic. On one hand, some scientists say everything is strictly determined by the laws of nature, and neither free will nor conscious intent have any involvement in what happens; but others say that the state of the underlying quanta that make-up everything is indeterminate until consciously observed with the intent to measure it. Mechanical materialism is why scientists say you have no free will, while you obviously experience that you do — and you are held responsible for your actions by society because you do. It is also why scientists cannot find a non-speculative explanation of consciousness on an evolutionary or biological level, even though being conscious is the most obvious aspect of being alive. And these contradictions have infected every aspect of our lives, and our world, by limiting our ability to see the world any other way. Even the formulation of spiritual doctrines is constrained today by this cognitive frame’s presence in our language. This is not an academic matter, as we see clearly in our failure, so-far, to change the path that has brought us to a global environmental collapse and the ecocide of life on Earth. -/- What is unique about the book’s approach is that it does not speculate about what might be the case, like so much of philosophy does. Instead, it relies upon meditative and contemplative insights that were gleaned directly from a dedicated advanced meditation practice over 60+ years of the author’s life. These insights were then confirmed by subsequent research into similar forms of this advanced meditation technique found across the world and throughout human history. In conjunction with my meditation practice, I have doctoral-level education in Philosophy and a 30-year career in Software Engineering. The latter was in part focused on automated software development, during which I was confronted with the unsolvable enigma — within the mechanical materialist understanding that I was enculturated into, and inculcated with — of Human Creativity. An enigma that set me on my path of discovery. -/- I have discovered, and continue to discover, just how productive this novel paradigm is in understanding ourselves and our world, by its ability to explain — in detail — so many of our experiences that are today either inexplicable, paradoxical, or ignored “for the present” by scientists until some hoped for mechanical description can be found. For the most part, scientists constrain themselves to describing mechanisms, but describing how is not explaining why — and that is why so much of our modern knowledge has a best-used-by-date. On the other side, seemingly all spiritual traditions accept this modern characterization of the world, ourselves, and reality that is manifest in our language, so that even spiritual phenomena and ideas are necessarily structured by it. We accept the ideas of separate beings, intentional entities, levels of consciousness, and attainment of enlightenment or unification with God, all of which are necessary because dead matter, and unconsciousness, are considered to be the starting point. It isn’t. Rather than just present this novel paradigm as a fait accompli, the book’s five sections bring the reader through stages of reconfiguration of our understanding: -/- Volume 1. The Way of Unsaying — The need for the articles in the first volume is not to tell the reader how things are, but to unsay the things that they have heard throughout their lives and have taken to heart. This is accomplished by exposing the logical and explanatory limitations of those ideas that usually go unnoticed. This is necessary to do in order to open the reader’s mind to other ways of accounting for phenomena, and navigating life, so that the reader will understand: first, why the meditation technique I will present is so effective; and second, why the novel paradigm that I propose will truly advance human knowledge and enable us to change our way of being in the world. In order to liberate oneself from seeing the world in a particular way I use skillful means to unseat all the understandings that we have all been inculcated with. This can be destabilizing, and you might find yourself getting annoyed, or even frightened. To paraphrase a Buddhist proverb: Better not to start; but if started, better to finish: -/- Volume 2. The Way of Contemplation — In this volume, the paradigm of Responsive Naturing is developed, building upon the dialogs in volume 1. This volume challenges the reader, since breaking free of one’s existing cognitive frame and paradigmatic understanding is not a trivial exercise, and neither is restructuring one’s thoughts to fit into a new paradigm. This section explains what Responsive Naturing means, how it works in both spiritual and scientific senses, my specific arguments for why it is the answer to our need for a better way to account for phenomena and experience, and how our way of being in the world can change because of it. I attempt to show, via a myriad of independent fields of study, just how powerful this paradigm is in explaining the various phenomena that until now, either had no scientific explanation, or had an incoherent and never proven one. -/- Volume 3. The Way of Tradition — This volume provides the reader with traditional descriptions of similar types of meditation to that which I am presenting. These techniques are related by the unusual support for meditation that they use: that of Inner Spontaneous Sound. This information is provided for two reasons: 1) to validate the technique I present in volume 4, The Way of Meditation, by showing the high esteem that these techniques have been held in by all spiritual traditions, and 2) to present a rational explanation for the technique’s effectiveness, based upon responsive naturing. Volume 4. The Way of Meditation — This volume describes the practice that I call “Great Responsiveness Meditation” which will allow the reader to: 1) engage in a long-term meditative and contemplative practice in order to attain the insights that are the foundation for the novel paradigm that I am presenting; and 2) to benefit from two unique side-effects of using inner spontaneous sound: one which protects the meditator during traumatic and extreme emotional experiences, especially of the kind now expected because of the current global environmental and societal crises; and the other — which is widely attested to — is an alchemical-like change in the meditator, who quickly displays compassion without self-centered concern. In Buddhism, this is known by the Sanskrit word “Mahākaruṇā,” which is the type of responsive compassion displayed by all enlightened beings. It is a permanent change in how we live our life, and it enables each of us to overcome our worst inculcated selfish behaviors. (shrink)

Concern about the ethics of clinical drug trials research on patients and healthy volunteers has been the subject of significant ethical analysis and policy development—protocols are reviewed by Research Ethics Committees and subjects are protected by informed consent procedures. More recently attention has begun to be focused on DNA banking for clinical and pharmacogenetics research. It is, however, surprising how little attention has been paid to the commercial nature of such research, or the unique issues that present when subjects are (...) asked to consent to the storage of biological samples. Our contention is that in the context of pharmacogenetic add-on studies to clinical drug trials, the doctrine of informed consent fails to cover the broader range of social and ethical issues. Applying a sociological perspective, we foreground issues of patient/subject participation or ‘work’, the ambiguity of research subject altruism, and the divided loyalties facing many physicians conducting clinical research. By demonstrating the complexity of patient and physician involvement in clinical drug trials, we argue for more comprehensive ethical review and oversight that moves beyond reliance on informed consent to incorporate understandings of the social, political and cultural elements that underpin the diversity of ethical issues arising in the research context.

This paper investigates the effects of relative position and proxemics in the engagement process involved in Human-Robot collaboration. We evaluate the differences between two experimental placement conditions for an autonomous robot in a collaborative task with a user across two different types of robot behaviours. The study evaluated placement and behaviour types around a touch table with 80 participants by measuring gaze, smiling behaviour, distance from the task, and finally electrodermal activity. Results suggest an overall user preference and higher engagement (...) rates with the helpful robot in the frontal position. We discuss how behaviours and position of the robot relative to a user may affect user engagement and collaboration, in particular when the robot aims to provide help via socio-emotional bonding.

This volume collects essays under four categories: religious traditions, religious life, emotional states, and historical and theoretical perspectives. These essays describe the ways in which emotions have played a role in various world religions, and analyze the manner in which key components of religious life ritual, music, gender, sexuality and material culture represent and shape emotional performance.

Rights of nature is an idea that has come of age. In recent years, a diverse range of countries and jurisdictions have adopted these norms, which involve granting legal rights to nature or natural objects, such as rivers, forests, or ecosystems. This book critically examines the idea of natural objects as right-holders, and analyses legal cases, policies, and philosophical issues relating to this development. -/- Drawing on contributions from a range of experts in the field, Rights of Nature: A Re-examination (...) investigates the potential for this innovative idea to revolutionize the concepts of rights, standing, and recognition as traditionally understood in many legal systems. Taking as its starting point Stone’s influential 1972 article ‘Should Trees Have Standing?’, the book examines the progress rights of nature have made since that time, by identifying central themes, unifying principles, and key distinctions in how rights of nature discourse has been operationalized in the disciplines of law, philosophy, and the social sciences. These themes and principles are illustrated through a wide variety of examples, including ecosystem services, indigenous thinking, and ecological restoration, demonstrating how the relationship between humanity and the natural world may be transforming. -/- Taking a philosophical, political, and legal perspective, this book will be of great interest to students and scholars of environmental law and policy, environmental ethics, and philosophy.

Since its inception as an international requirement to protect patients and healthy volunteers taking part in medical research, informed consent has become the primary consideration in research ethics. Despite the ubiquity of consent, however, scholars have begun to question its adequacy for contemporary biomedical research. This book explores this issue, reviewing the application of consent to genetic research, clinical trials, and research involving vulnerable populations. For example, in genetic research, information obtained from an autonomous research participant may have significant bearing (...) on the interests of family members who have not consented to the study. This casts doubt on the adequacy of consent for such studies. This book also questions the assumptions that informed consent is essential and that it satisfactorily protects the principle of individual autonomy. It reviews recent empirical studies that challenge the possibility of truly informed consent and highlights the extent to which consent is governed by social norms and expectations. It also investigates how consent might be of secondary importance in some circumstances, for example when a research project appears to protect a public or community interest. (shrink)

Simmias' famous epiphenomenalist analogy of the soul-body relation to the harmony and strings of a lyre leads to Socrates' initial refutation and subsequent prolonged defense of soul's immortality in the Phaedo. It also yields in late antiquity significant treatments of the harmony relation by Plotinus and Porphyry that present a larger context for viewing the nature of harmony in the soul and the psycho-somatic compound. But perhaps the most detailed treatment of the musical analogy, and certainly the most radical, is (...) to be found in Gregory of Nyssa's De Hominis Opificio. Gregory's remarkable development of the musical instrument analogy provides a multi-layered analysis of interrelated causality on the mechanistic, physiological, psycho-somatic and intellectual/spiritual planes. Gregory not only sees mind/soul and body as radically equal and yet multilayered in their mutual development; he also refuses to restrict mind to the brain alone, for all physiological systems, in his view, are holistically and individually expressive of mind's activity. Gregory's theory is more innovative than Augustine's view of the mind/soul-body relation and, in my view, the most important account between Plotinus and Aquinas. (shrink)
