This paper offers a new approach to the philosophical foundations of information systems through feminist philosophy and, in particular, feminist epistemology. This can be used to expose the universalizing tendency of many information systems and to show the importance of using real-life complex examples rather than the simplified examples often favored by philosophers. Within traditional epistemology and its relation to IS, subjectivity, the propositional/skills distinction and epistemic hierarchies are subject to arguments from feminist epistemology. With respect to the emerging critical (...) school of IS, feminist epistemology, and within that, feminist standpoint theory, are used to examine the complexities of the positivist/anti-positivist position and the related concept of emancipation. In addition, it is argued that the liberal version of emancipation encapsulated in such systems may have an effect opposite to that of emancipation These issues are illustrated in an existing expert systems project.

We will show that there is a strong form of emergence in cell biology. Beginning with C.D. Broad's classic discussion of emergence, we distinguish two conditions sufficient for emergence. Emergence in biology must be compatible with the thought that all explanations of systemic properties are mechanistic explanations and with their sufficiency. Explanations of systemic properties are always in terms of the properties of the parts within the system. Nonetheless, systemic properties can still be emergent. If the properties of the components (...) within the system cannot be predicted, even in principle, from the behavior of the system's parts within simpler wholes then there also will be systemic properties which cannot be predicted, even in principle, on basis of the behavior of these parts. We show in an explicit case study drawn from molecular cell physiology that biochemical networks display this kind of emergence, even though they deploy only mechanistic explanations. This illustrates emergence and its place in nature. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Harris levels two main criticisms against our original defence of QALYs (Quality Adjusted Life Years). First, he rejects the assumption implicit in the QALY approach that not all lives are of equal value. Second, he rejects our appeal to Rawls's veil of ignorance test in support of the QALY method. In the present article we defend QALYs against Harris's criticisms. We argue that some of the conclusions Harris draws from our view that resources should be allocated on the basis of (...) potential improvements in quality of life and quantity of life are erroneous, and that others lack the moral implications Harris claims for them. On the other hand, we defend our claim that a rational egoist, behind a veil of ignorance, could consistently choose to allocate life-saving resources in accordance with the QALY method, despite Harris's claim that a rational egoist would allocate randomly if there is no better than a 50% chance of being the recipient.

Harris argues that if QALYs are used only 50% of the population will be eligible for survival, whereas if random methods of allocation are used 100% will be eligible. We argue that this involves an equivocation in the use of "eligible", and provides no support for the random method. There is no advantage in having a 100% chance of being "eligible" for survival behind a veil of ignorance if you still only have a 50% chance of survival once the veil (...) is lifted. A 100% chance of a 50% chance is still only a 50% chance. We also argue that Harris provides no plausible way of dealing with the criticism that his random method of allocation may result in the squandering of resources. (shrink)

Individuals make decisions under uncertainty every day. Decisions are based on in- complete information concerning the potential outcome or the predicted likelihood with which events occur. In addition, individuals’ choices often deviate from the rational or mathematically objective solution. Accordingly, the dynamics of human decision making are difficult to capture using conventional, linear mathematical models. Here, we present data from a 2-choice task with variable risk between sure loss and risky loss to illustrate how a simple nonlinear dynamical system can (...) be employed to capture the dynamics of human decision making under uncertainty (i.e., multistability, bifurcations). We test the feasibility of this model quantitatively and demonstrate how the model can account for up to 86% of the observed choice behavior. The implications of using dynamical models for explaining the nonlin- ear complexities of human decision making are discussed as well as the degree to which the theory of nonlinear dynamical systems might offer an alternative framework for understanding human decision making processes.

The use of the Quality Adjusted Life-Year (QALY) as a measure of the benefit obtained from health care expenditure has been attacked on the ground that it gives a lower value to preserving the lives of people with a permanent disability or illness than to preserving the lives of those who are healthy and not disabled. The reason for this is that the quality of life of those with illness or disability is ranked, on the QALY scale, below that of (...) someone without a disability or illness. Hence we can, other things being equal, gain more QALYs by saving the lives of those without a permanent disability or illness than by saving the lives of those who are disadvantaged in these ways. But to do so puts these disadvantaged people under a kind of double jeopardy. Not only do they suffer from the disability or illness, but because of it, a low priority is given to forms of health care that can preserve their lives. This, so the objection runs, is unjust or unfair. This article assesses this objection to the use of QALYs as a basis for allocating health care resources. It seeks to determine what is sound in the double jeopardy objection, and then to show that the defender of QALYs has an adequate response to it. (shrink)

In an article published in 1993, J. Vaahtera argued that voting at Rome may have originally entailed the clashing of arms. This paper returns to this idea, to explore some of its possible implications. The discussion is necessarily conjectural, simply because, for so many of the important issues, there is just no evidence. For the same reason, the chronology of the various possible developments is inevitably vague. Certainty is impossible, as is always the case with the study of archaic Rome. (...) But, for all that, Vaahtera’s idea does have the potential to shed some light on the origins of some of the distinctive features of Roman voting practices. (shrink)

In contrast to certain recent work, which supposes that the fetial priests were always responsible for the swearing of the oaths made upon the striking of a treaty and that the rituals they performed went unchanged for centuries, this paper argues that the treaty-making rituals of the Romans changed and developed, and that the ritual which the fetial priests performed may not have been devised until as late as the third century BC.

In 209b.c.P. Cornelius Scipio captured the city of New Carthage. The victory was crucial for the Roman war effort in Spain, and indeed in Italy too, but Scipio's campaign is especially memorable—and the subject of much debate—on account of the manner in which the city was taken. New Carthage had in effect been built on a peninsula, with the sea to the south and a lagoon to the north, and with a canal joining the two to the west. The city, (...) therefore, could only be approached by land from the east; but, according to Polybius, Scipio had learnt from some fishermen that the lagoon was shallow and could be forded in most places and, moreover, that the waters in it usually receded each evening (10.8.7). It was this knowledge that Scipio exploited to take the city. But this same knowledge he also kept from his men (10.9.1, 10.9.4–5). In his address to his soldiers prior to the attack, Polybius says, Scipio told them that Poseidon had visited him in his sleep and had promised to assist the Romans in their operations in a way that would be apparent to all (10.11.7).

J. H. van 't Hoff's 1874 Dutch pamphlet, in which he proposed the spatial arrangement of atoms in a molecule, is one of the most significant documents in the history of chemistry. This essay presents a new narrative of Van 't Hoff's early life and places the appearance of the pamphlet within the context of the 'second golden age' of Dutch science. We argue that the combination of the reformed educational system in The Netherlands, the emergence of graphical molecular modelling (...) within the theoretical and practical culture of chemistry during the 1860s and 1870s, as well as Van 't Hoff's own personal research trajectory, formed the background to his unprecedented attribution of spatial meaning to the traditional concept of atomic 'arrangement'. We also present a new English translation of the pamphlet, for we have found that the existing translation, published by G. M. Richardson in 1901, contains many errors, changes and omissions. The new version offers a more accurate rendition in English of Van 't Hoff's style and argument. (shrink)

This paper describes the application of eight statistical and machine-learning methods to derive computer models for predicting mortality of hospital patients with pneumonia from their findings at initial presentation. The eight models were each constructed based on 9847 patient cases and they were each evaluated on 4352 additional cases. The primary evaluation metric was the error in predicted survival as a function of the fraction of patients predicted to survive. This metric is useful in assessing a model’s potential to assist (...) a clinician in deciding whether to treat a given patient in the hospital or at home. We examined the error rates of the models when predicting that a given fraction of patients will survive. We examined survival fractions between 0.1 and 0.6. Over this range, each model’s predictive error rate was within 1% of the error rate of every other model. When predicting that approximately 30°K of the patients will survive, all the models have an error rate of less than 1.5%. The models are distinguished more by the number of variables and parameters that they contain than by their error rates; these differences suggest which models may be the most amenable to future implementation as paper-based guidelines.

The word τερθρεία, which L. and S.8 derived from τερατεία and translated ‘the use of claptraps’, is perhaps best known from its occurrence in Isocrates , but the new edition has spread the net more widely, citing Philo, Philodemus, Proclus, Galen, Dion. Hal., and giving its meaning as ‘the use of extreme subtlety, hair-splitting, formal pedantry’. This agrees better with the gloss / κενοσπονδία attributed to Orus of Miletus in Et. Mag. 753. 4. Aristotle, Demosthenes, and Plutarch each use τερθρεύομαι (...) once. In the Helen Isocrates, condemning the futile ingenuity of the Sophists in writing encomia on such unworthy objects as salt and humble-bees, holds that such tours de force are immoral, as tending to deceive, representing a literary form of the vice περιεργία. Τερθρεία, then, should take its place, as a recognized term for the idle over-elaboration of a banausic theme, in the vocabulary of Greek literary criticism. It does not, however, appear in Rhys Roberts's ‘Glossary of Greek Rhetoric’ appended to his edition of D.H.'s On Literary Composition. No doubt this is because τερθρεία does not occur in this or any other of D.H.'s Scripta Rhetorica. But D.H. himself uses the word in Antiq. Rom. . Similarly J. F. Lockwood does not discuss the term in his lists in C.Q. xxxi and xxxii, where he collects words which are used metaphorically by D.H. in literary criticism. The metaphor in τερθρεία is certainly not obvious; but the literary sense must have involved some transference of meaning, for it is not to be expected that the word τερθρεία sprang, in full panoply of critical significance, from the brain of the Muse of Rhetoric; and it is part of the purpose of this paper to point the way to an explanation, or at least to set forth some known facts about the word and its possible congeners.

From the late 1790s to the early 1890s, Scottish scholars contributed, as translators, commentators, or critics to the ‘reception’ of Kant's philosophy in Britain. The discussion here considers particularly the work of Richardson, Semple, Gillies, MacVicar, Ferrier, Meiklejohn, and Hastie, and attempts to assess the character, quality, and value of their contributions to Kantian scholarship. An important question throughout is whether – and if so, how far and why – the work of Scottish Kantians can be meaningfully discussed apart (...) from their English contemporaries – one relevant consideration being the distinctive rôle of philosophy in the Scottish M.A. curriculum.

This is an engaging book on a subject which most people in our culture assume went out of fashion long ago. The book had its genesis in one of a series of symposia convened by the Church Society for College Work of Cambridge to explore certain themes and ideas which have great import for our time. The various authors of the essays eschew the habit of viewing Transcendence as the traditional content of metaphysical arguments or revelatory statements about the nature (...) of God outside or independent of the world and seek for signs of the possibility of achieving a renewed sense of Transcendence in the domains of inner experience, history, culture, language, science, technology, and the arts. Huston Smith suggests two options of human fulfillment: psychological and ontological, both providing a kind of transcendence of self and society. He refuses to accept one and reject the other but instead to convince us that both are legitimate. M. Murphy claims that the experience of psychological and social transcendence can be fostered by educational projects such as encounter groups, gestalt therapy workshops and sensitivity training programs. In his "Manifesto for a Dionysian Theology," Sam Keen analyzes the Apollonian way of reasoning and planning which has come to dominate in Western culture and makes a plea for a reassertion of the Dionysian principle in religion which might be expressive of life as dance, centrality of feelings and sensations, a pantheistic conception of God and a theology of play. Harvey Cox asserts that our society has lost its capacity for utopian fantasy resulting in the inability to conceive of any world which is not a mere modification or extension of our own world. He suggests that we consciously become "fools for Christ" again and give full rein to our powers of creative fantasizing even at the risk of contracting "religious madness." Donald Schon urges post-modern man to give up hope for achieving a stable political order and to develop an "ethic for change" appropriate to the demands of our society where change is all-pervasive. Essays by R. Bellah and H. Richardson explore myths of transcendence as ordering structures in society and plead for increased attention to correspondences among the disciplines of theology, sociology, and psychology. E. Fackenheim and W. Kaufman seek to clarify the notion of transcendence in Judaism and Christianity respectively and to "clear the way for a positive revelation." In keeping with the shared notion that transcendent reality is present and active within the human process, two eminent process philosophers, Wieman and Hartshorne discuss the "implications for a concept of transcendence that follows from affirming the creative freedom of man." The essays singly and together reject the notion that the existence and nature of transcendent reality can be arrived at by pursuing a single line of argumentation to its bitter end and instead they work together from various points of view to reinforce our sense of man's renewed thirst for the Divine and the subsequent rediscovery of God's uninterrupted presence within the world of "Immanent Possibility."--J.
