The decision-making environment in intensive care units (ICUs) is influenced by the transformation of intensive care medicine, the staffing situation and the increasing importance of patient autonomy. Normative implications of time in intensive care, which affect all three areas, have so far barely been considered. The study explores patterns of decision making concerning the continuation, withdrawal and withholding of therapies in intensive care. A triangulation of qualitative data collection methods was chosen. Data were collected through non-participant observation on a (...) surgical ICU at an academic medical centre followed by semi-structured interviews with nurses and physicians. The transcribed interviews and observation notes were coded and analysed using qualitative content analysis according to Mayring. Three themes related to time emerged regarding the escalation or de-escalation of therapies: influence of time on prognosis, time as a scarce resource and timing in regards to decision making. The study also reveals the ambivalence of time as a norm for decision making. The challenge of dealing with time-related efforts in ICU care results from the tension between the need to wait to optimise patient care, which must be balanced against the significant time pressure which is characteristic of the ICU setting.

This dissertation explores the influence of time constraints on different research practices. The first two parts present case studies, which serve as a basis for discussing the epistemological and ethical implications of temporal limitations in scientific research. Part I is a case study on gravitational wave research, conducted by the LIGO Scientific Collaboration. This exemplifies fundamental research – without immediate societal applications, open-ended in terms of timeline and in terms of research goals. It is based, in part, on qualitative (...) interviews conducted with gravitational wave physicists. I show that considerations about time and speed play a role in every stage of research: goal setting, method design, and the evaluation and communication of results. Part II provides a case study on translational medicine, an approach explicitly dedicated to accelerating research in order to develop and implement new therapies. This epitomizes applied research with high social stakes, motivated by non-epistemic goals. Here, epistemic trade-offs between speed and reliability intersect with ethical trade-offs between different types of harms. In Part III, the insights from both of these case studies are used as the basis for a more general discussion concerning the pragmatic aspects of epistemic practices, especially in relation to current debates centered on the role of values in science. A particular focus is on the value of speed and the ability to generate reliable results, either via choice of methods, or via decisions about which goals to set, as well as decisions about when to stop further testing. The primary thesis of the dissertation is that pragmatic considerations stemming from limitations of resources are a necessary feature of the pursuit of epistemic aims, and that the epistemic is thus inherently pragmatic.

At last his students and colleagues, his friends and his friendly critics, his fellow-scientist and fellow-philosophers, have the works of Milic Capek before them in one volume, aside from his books of course. Now the development of his interests and his thoughts, always led centrally by his concern to understand 'the philosophical impact of contemporary physics', becomes clear. In the nearly 90 essays and papers, and in his book on the philosophical impact as well as his classical restatement of process (...) philosophy in his Bergson and Modern Physics, Professor Capek establishes one of the fundamental alternatives to the comprehension of human experience, and thereby of the world. Capek is certainly to be seen with respect and admiration, for he has dealt with the deepest and toughest of scientific as well as metaphysical problems: his major efforts in the philosophy of mind focussed upon the time of experience, and in the philosophy of physics focussed upon continuity, causality and again the temporal, now in the world-picture.

The contemporary view of the fundamental role of time in physics generally ignores its most obvious characteric, namely its flow. Studies in the foundations of relativistic mechanics during the past decade have shown that the dynamical evolution of a system can be treated in a manifestly covariant way, in terms of the solution of a system of canonical Hamilton type equations, by considering the space-time coordinates and momenta ofevents as its fundamental description. The evolution of the events, as (...) functions of a universal invariant world, or historical, time, traces out the world lines that represent the phenomena (e.g., particles) which are observed in the laboratory. The positions in time of each of the events, i.e., the time of their potential detection, are, in this framework, controlled by this universal parameter τ, the time at which they are generated (and may proceed in the positive or negative sense). We find that the notion of thestate of a system requires generalization; at any given τ, it involves information about the system at timest(τ) ≠ τ. The correlation of what may be measured att(τ) with what is generated at τ is necessarily quite rigid, and is related covariantly to the spacelike correlations found in interference experiments. We find, furthermore, that interaction with Maxwell electromagnetism leads back to a static picture of the world, with no real evolution. As a consequence of this result, and the requirement of gauge invariance for the quantum mechanical evolution equation, we conclude that electromagnetism is described by a pre-Maxwell field, whose τ-integral (or asymptotic behavior as τ → ∞) may be identified with the Maxwell field. We therefore consider the world of events in space time, interacting through τ-dependent pre-Maxwell fields, as far as electrodynamics is concerned, as the objective dynamical reality. Our perception of the world, through laboratory detectors and our eyes, are based onintegration over τ over intervals sufficiently large to obtain an aposteriori description of the phenomena which coincides with the Maxwell theory. Fundamental notions, such as the conservation of charge, rest on this construction. The decomposition of the common notion of time into two essentially different aspects, one associated with an unvarying flow, and the second with direct observation subject to dynamical modification, has profound philosophical consequences, of which we are able to explore here only a few.

In his vigorous defense of the reality of time, Capek champions a tradition of process philosophy that includes such figures as Bergson, James, and Whitehead, against both philosophers and physicists that subordinate time to some lower status in reality or regard it as a peculiar dimension of space. This is, in fact, the point of his last essay in this volume, "Time-Space Rather than Space-Time," where he argues, contrary to standard interpretations, that relativity physics does not (...) necessitate a frozen "block universe" that includes preexisting future events.

I would like to present a partial account of an investigation into scientifically and philosophically significant changes which quantum physics has made necessary in our views of time. In some cases, these changes resulted from discoveries of new aspects of time, as illustrated by the so-called “T.C.P. Theorem” due to Schwinger, Pauli and Lüders. Their finding determines the transformation of the quantum state of any physical system resulting from a reversal of the direction of time, followed (...) by a reorientiation of the dimensions of space and the replacement of each particle in the system with its antiparticle. A relativistic interpretation of the T.C.P. Theorem in Section III will show that it amounts to the universal interrelatedness of time, space and matter. In other cases, the changes in the scientific concept of time follow from the availability of new methods provided by quantum physics rather than from discoveries of unknown aspects of time. These methods may be applied to issues which bothered philosophers and physicists obsessed with the enigma of time long before Planck’s quantum of action started our century. The quantum approach of von Neumann, Pauli, Fierz and Lüdwig to the second law of thermodynamics and the associated irreversibility or asymmetry of time illustrate the use of the new methods for the solution of old problems of time. The relevance of quantum physical methods to the problem of reality of time will be shown in the last section of this paper. (shrink)

The aim of this paper is to present a new perspective under which branching-time semantics can be viewed. The set of histories (maximal linearly ordered sets) in a tree structure can be endowed in a natural way with a topological structure. Properties of trees and of bundled trees can be expressed in topological terms. In particular, we can consider the new notion of topological validity for Ockhamist temporal formulae. It will be proved that this notion of validity is equivalent (...) to validity with respect to bundled trees. (shrink)

We consider three possible reasons why humans might accord a privileged status to emotional information when mentally traveling backward or forward in time. First, mental simulation of emotional situations helps one to make adaptive decisions. Second, it can serve an emotion regulation function. Third, it helps people to construct and maintain a positive view of the self.

Heidegger's phenomenological approach, as exhibited in Being and Time, provides a conceptual background to discussions in role?theory. His work was not meant as an empirical contribution to sociology, nor does he assimilate sociology to conceptual inquiry. Heidegger's contention is, rather, that if we understand the way in which human beings exist (the nature of Dasein) we shall understand why empirical role?theoretical inquiries are possible. Without experience, without paying attention to the facts of human life, there could be no phenomenological (...) enterprise. But by eliciting the fundamental structure of Dasein Heidegger has pointed to what makes the empirical data ultimately intelligible. The enterprise is a transcendental one, in the Kantian sense.

Attributed to Alexander of Aphrodisias -the leading ancient commentator on Aristotle -the Quaestiones exemplify the process through which Aristotle's thought was organized and came to be interpreted as "Aristotelianism." This volume of R.W. Sharples's translation, together with his earlier translation of Quaestiones 1.1-2.15, makes the Quaestiones available in its entirety for the first time in a modern language. The Quaestiones are concerned with problems of physics and metaphysics, psychology and divine providence. Readers interested in Aristotle's psychological views will find (...) the second half of the Quaestiones particularly valuable. Ten of the problems discussed involve issues raised in Aristotle's On the Soul, including the unity of apperception and the transition from first to second actuality in the act of contemplation. An additional twelve problems relate to aspects of physical theory such as infinity, necessity, and potentiality. Quaestio 2.21 concerns divine providence and helps supplement our knowledge of Alexander's position. A study of the Quaestiones also suggests how interpretations of Aristotle were influenced by doctrines of Hellenistic philosophy. Translated first into Arabic and then into Latin, excerpts from the Quaestiones played a significant role in the transmission of ancient Greek philosophy to the medieval world. (shrink)

Two recent events have caused renewed anxiety concerning the ethics of donor transplantation. The first is the report of the British Transplantation Society and the second is the Bill introduced by Mr Tam Dalyell MP (see page 61 of this issue) in which he seeks to establish by law that unless an individual in his life time has expressly contracted out his organs may after death be used for transplantation. Dr Mahoney in this paper therefore examines from the point (...) of view of ethics some of the personal and social aspects of both proposals. (shrink)

Throughout the ages, the mystery of what happens when we die and the nature of the human mind has fascinated humankind. In this collection of essays, leading scientists and authors contemplate the nature of consciousness, quantum mechanics, string theory, dimensions, space and time, non-local space, the hologram, and the effect of death on the consciousness"--Provided by publisher.

As a continuation of this author’s previous cosmological neuroscience papers on the hypothesized Soul of Multiverse and its possible laws, the present work examined the social aspects of four of these laws. The following key aspects were recognized: (1) Knowing about the cosmic Law of Coexistence in Diversity can let our mind respect not only the endless diversity of human beings but also the cohesive force of space-time in which all are connected. This may help realizing the (...) superiority of cooperation for shared goals over competition for gaining by harming others. (2) Knowing about the cosmic Law of Truth in Complexity can ready our mind to confront the problems of societies with the understanding that these problems are much more complex than generally thought. This may help initiating the needed intellectual renaissance of the 21st century. (3) Knowing about the cosmic Law of Divine - Evil Asymmetry can make our mind appreciate the slight yet sufficient supremacy of divine over evil. This may help restoring faith in the eventual creation of a just society, where social justice is defined as an administrative mechanism providing the right conditions for every human being to accomplish his or her Conscience-led Mission throughout life, while allowing each of these accomplishments to be reciprocated with the gratitude it induced in the involved social systems, small or large, to let equal opportunities in life coexist with due diversity in welcomed, not abused, social recognitions. And (4) knowing about the cosmic Law of Lives to Transcend can empower our mind to build on these advances. This may help moving evolution towards the human species worthy of its origin and destination. (shrink)

It is widely assumed that time appears to be tensed, i.e. divided into a future, present and past, and transitory, i.e. involving some kind of ‘flow’ or ‘passage’ of times or events from the future into the present and away into the distant past. In this paper I provide some reasons to doubt that time appears to be tensed and transitory, or at least that philosophers who have suggested that time appears to be that way have included (...) in ‘appearance’ everything that falls under the broad term ‘cognition’, i.e. mental processes of all kinds, including perceiving, remembering, imagining, and thinking. I argue that the tensed and transitory aspect of our experience of temporal reality is, firstly, subordinate to our experience of a world of persistent objects, secondly, in conflict with a popular conception of the nature of persistent material objects, and finally, that it is an aspect of how we think about temporal reality rather than how we actually experience it. I support the last contention by a comparison with our experience of spatiality, which arguably has three distinguishable components: (i) ‘pure input perception’, (ii) ‘perceptual experience modulated by top down cognitive processes’, and (iii) a ‘pure representation of space’. For space, the modulation of our perception of space at any given moment is highly influenced by our pure representation of space, but it is not clear to me that our modulated experience of space is influenced by a pure representation of time. Rather, the modulated experience of temporality, to my mind, is much more clearly an experience of continuous existence of the persisting objects that make up the world. (shrink)

The most obvious cases of ego-involvement in conscious life are those which Husserl calls conscious acts or cogitationes.[2] They are the most obvious cases because they are the ones in which the ego explicitly involves himself in some way ; they exhibit the character of being engaged in by the ego or having been engaged in by him. This ego-quality or character belongs demonstrably to every conscious process in which the ego engages or lives. In the ego's conscious life, the (...) life to which his, her, or its acts belong, there also occur mental or intentive processes in which the ego does not or did not engage, and these Husserl calls passive or non-actional processes as contrasted with the active or actional processes characterized by egoengagement.

Originally published in 1940, this book contains a succinct introduction to Boethius, the influential medieval philosopher who was writing during the final days of the Western Roman Empire. Barrett keeps the general reader in mind as she explains Boethius' philosophy and his role in keeping Greek thinking available to his fellow Romans even as they were being conquered by the Ostrogoths. This book will be of value to anyone with an interest in ancient thought and in Late Antique philosophy.

In her book Specifications Grading, Linda B. Nilson advocates for a grading regimen she claims will save faculty time, increase student motivation, and improve the quality and rigor of student work. If she is right, there is a strong case for many faculty to adopt some version of the system she recommends. In this paper, we argue that she is mostly right and recommend that faculty move away from traditional grading. We begin by rehearsing the central features of specifications (...) grading and providing two examples of how to implement it in philosophy classes. In light of the examples, we argue that specifications grading fulfills two of Nilson’s central desiderata but not the third. Since specifications grading generates two benefits that when combined increase student learning, without adding or increasing burdens, we conclude that student learning increases when courses are revised to include aspects of specifications grading.

In lieu of an abstract, here is a brief excerpt of the content:Walking the Bodhisattva Path/Walking the Christ PathU.S. Conference of Catholic BishopsCatholics and Buddhists brought together by Dharma Realm Buddhist Association, the San Francisco Zen Center, and the United States Conference of Catholic Bishops (USCCB) met 20-23 March 2003 in the first of an anticipated series of four annual dialogues. Abbot Heng Lyu, the monks and nuns, and members of the Dharma Realm Buddhist Association hosted the dialogue at the (...) City of Ten Thousand Buddhas in Talmage, California. The community had transformed their Confucius Hall into a chapel, with a large, newly constructed wooden cross on a wall above an altar facing out from a raised platform, so the Catholic delegation would have a space for worship. A special poster announcing the theme of the conference, "Walking the Bodhisattva Path/Walking the Christ Path," showing a Buddhist dharma wheel at one foot of a bridge and a Celtic cross at the other foot, had been created by the hosting community.The daily schedule for the dialogue did not interfere with the monastic routine at the City of Ten Thousand Buddhas, which included early morning chanting (4:00-5:00 am), daily rituals in the Buddha Hall, and the single large meal for monastics before noon to which all participants were invited. Catholics and Buddhists meeting in the dialogue began each day with an optional forty-five minutes of quiet sitting together in the monastery meditation hall, each following their own form of meditation and prayer. There was a Eucharist on Friday and Saturday evenings for the Catholics and to which the Buddhists were invited, and additional meals of breakfast and supper throughout the meeting at the City's Jyun Kang Restaurant.Fourteen Buddhists and fourteen Catholics participated in the formal discussions. Each participant spoke on what it means to them to follow Christ or the way of the Bodhisattvas or enlightened beings. In addition to speaking, each participant distributed a short passage, usually from a traditional text, on this topic. Several passages from Master Dogen's Shobogenzo and the Gospel of John were among those shared by the group. Other passages shared were taken from the Avatamsaka Sutra and the Shurangama Sutra and from the other gospels and the writings of Zen master HakuinZenji, the Dalai Lama, Korean Zen Master I-sahn Hye-yeon, the teachings of Master [End Page 247] Hsuan Hua, Shantideva, Origen, St. Ignatius, St. Benedict, the author of The Cloud of Unknowing, St. John of the Cross, and Chiara Lubich. A minute of silence separated the fifteen-minute segments for each presentation. With so large a group, most of the time in the formal sessions involved listening to series of presentations; however, during discussion periods the participants asked several challenging questions of one another.Some participants noted the tension they felt between belonging to a particular religious group and the need to let go of any consequential narrowness. The goal of the discussion was to promote understanding of the differences and similarities between Christianity and Buddhism. At one point, the participants noted several concerns about mutual enrichment: whether Buddhist methods can be separated from Buddhism and Christian methods from Christianity, and what specific aspects of Christian practice truly enrich Buddhists and which Buddhist practices likewise enrich Christians. Several times participants discussed their understanding of terms such as transformation, grace, the incarnation and the passion of Jesus, discernment of spirits, prayer, Buddha-nature, and related terms. There was consensus that Buddhists and Catholics can practically help one another regarding mental cultivation and religious precepts. They expressed this consensus in their choice of the topic forthe next dialogue, "Transformation of Hearts and Minds: Chan/Zen-Catholic Approaches to Precepts."The group agreed to reconvene in 2004 to respond to six presentations, three from each side, on different aspects of this topic.Chairing the sessions were Rev. Heng Sure for the Dharma Realm Buddhist Association, Rev. Taigen Dan Leighton for the San Francisco Zen Center, and Bishop John Webster for the United States Conference of Catholic Bishops. Their three organizations are the sponsors of the Northern California Chan/Zen-Catholic Dialogue. Chan and Zen are respectively the Chinese and Japanese terms for the meditation school... (shrink)

Although most aspects of world and self-consciousness are inherently subjective, neuroscience studies in humans and non-human animals provide correlational and causative indices of specific links between brain activity and representation of the self and the world. In this article we review neuroanatomic, neurophysiological and neuropsychological data supporting the hypothesis that different levels of self and world representation in vertebrates rely upon i) a 'basal' subcortical system that includes brainstem, hypothalamus and central thalamic nuclei and that may underpin the primary (...) (or anoetic) consciousness likely present in all vertebrates; and ii) a forebrain system that include the medial and lateral structures of the cerebral hemispheres and may sustain the most sophisticated forms of consciousness (e.g. noetic (knowledge based) and autonoetic, reflective knowledge). We posit a mutual, bidirectional functional influence between these two major brain circuits. We conclude that basic aspects of consciousness like primary self and core self (based on anoetic and noetic consciousness) are present in many species of vertebrates and that, even self-consciousness (autonoetic consciousness) does not seem to be a prerogative of humans and of some non-human primates but may, to a certain extent, be present in some other mammals and birds.

An important aspect of the debate between the A-theory and the B-theory of time relates to the supposed implications of each for some of the most basic human attitudes and stances. The asymmetry in our attitudes towards past and future events in our life (pleasant and unpleasant), and towards the temporal limits of our existence, that is, toward birth and death, is supposedly considered differently by the two theories. I argue that our attitudes are neither justified nor discredited by (...) anything which is in debate between the A-Theory and the B-theory, and therefore that neither theory of time is supported by the asymmetry in our attitudes.
