Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

Our intention here is to present the essential character of classical, sunnī kalām within a strictly formal perspective and to set out its basic aspects. It was conceived by the mutakallimīn as a rational, conceptual, and critical science and, although kalām differed in a number of basic concepts and constructs and in its analytic system, the topical organisation of the major compendia parallels that of metaphysics as understood in the contemporary Aristotelian tradition. The debates between kalām and falsafa need to (...) be examined within this context. Kalām, however, is theological in the strict sense of the term and it is as such that its problematic and its procedures are primarily to be understood. Thus seen, the object of kalām is to rationalise the cognitive content presented to Believers in the symbolic language of the koranic revelation. It has, then, four principal tasks, sc, to conceptualise, to order, to explain, and where possible to justify the primary doctrines of the community whose belief is held to be normative. Within this framework the differences that characterise the major schools as such and the various tendencies of individual masters within each school may readily be brought to light. On se propose ici de présenter, d'un point de vue strictement formel, la nature du kālam classique sunnite et d'identifier ses caractéristiques principales. II avait été conçu par les mutakallimin comme une science rationelle, conceptuelle et critique. L'organisation des matières dans ses traités reprend celle de la métaphysique dans la tradition aristotélicienne de l'époque, bien que le kalām s'en distingue par plusieurs de ses structures et concepts fondamentaux, ainsi que par son système analytique. C'est dans ce contexte qu'il faut considérer les debats qui s'instaurèrent entre kalām et falsafa. Le kalām, cependant, est d'ordre strictement théologique et c'est principalement dans ce cadre qu'il faut comprendre sa problématique et ses procédures. Le kalām a pour fonction de rationaliser le contenu cognitif offert aux croyants dans le langage symbolique de la révélation coranique. Il en résulte quatre tâches principales; il s'agit de conceptualiser, ordonner, expliquer et, dans le mesure du possible, justifier les doctrines principales reconnues par la communauté faisant référence en matière de croyance. Dans ce cadre, il sera possible de mettre en lumière les différences entre les principales écoles, ainsi que les tendances qui distinguent certains de leurs grands maîtres respectifs. (shrink)

Richard M Weaver, a thinker and writer celebrated for his unsparing diagnoses and realistic remedies for the ills of our age, is known largely through a few of his works that remain in print. This new collection of Weaver's shorter writings, assembled by Ted J Smith III, Weaver's leading biographer, presents many long-out-of-print and never-before-published works that give new range and depth to Weaver's sweeping thought. Included are eleven previously unpublished essays and speeches that were left in near-final form (...) at the time of Weaver's death in 1963. In all, there are some one hundred and twenty-six essays, speeches, book reviews, and editorials. (shrink)

Many of the errors that occur in children' subtraction are due to the use of incorrect strategies rather than to the incorrect recall of number facts. A production system is presented for performing written subtraction which is consistent with an earlier analysis of the nature of such a cognitive skill. Most of the incorrect strategies used by schoolchildren can be accounted for in a principled way by simple changes in the production system, such as the omission of individual rules or (...) the inclusion of rules appropriate to other arithmetical tasks. The production system model is evaluated against a corpus of over 1500 subtraction problems done by 10‐year olds and is shown to account for about two‐thirds of the (nonnumber fact) errors. It also provides an alternative, simpler interpretation of the subtraction errors analysed by Brown and Burton (1978). Some implications for teaching are discussed. (shrink)

The present study seeks to lay out the most basic elements of the ontology of classical Aš‘arite theology. In several cases this requires a careful examination of the traditional and the formal lexicography of certain key expressions. The topics primarily treated are: how they understood “Being/ existence” and “being/existent” and essential natures; the systematic exploitation of the equivocities of certain expressions within a general context in which other than words there are no universals proves to be elegant as well as (...) insightful; the basic categories of primary entities: independant beings and nonindependant beings, created and uncreated, the equivocity of “being/existent” as predicated of contingent entities on the one hand and of God and His attributes on the other, and certain problems that arise because of the rigid application of the system's underlying analytic principles. Nous essayons ici de presenter les éléments fondamentaux de l'ontologie de l'aš‘arisme classique. Pour quelques expressions, il a fallu examiner la lexicographie et ordinaire et technique pour bien comprendre leur emploi et leur signification. Les sujets examinés sont: le sens de “Etre/existence” et de “être/existant” et le concept de réalité essentielle; l'emploi nuancé des équivocités de quelques expressions dans un contexte où les seuls universaux sont des mots, emploi qui se révèle philosophiquement élégant; les catégories fondamentales des êtres: êtres indépendants et êtres non-indépendants, soit créés soit incréés, l'équivocité de “être/existant” dit des êtres contingents d'une part, de Dieu et ses attributs d'autre part, et enfin quelques difficultiés qui résultent de l'application rigide des principes analytiques du système.

After a brief, personal reflection on Aron Gurwitsch's life and his many influences on my career, I devote this lecture to some of the central themes of a phenomenology of medicine. Its core is the clinical encounter, which displays a certain structure I term the asymmetry of power and vulnerability —a complex contextual imbalance characterized by multiple points of view, hence points for reflective entrance. These are then interpreted phenomenologically in terms of epoché and reduction, evidence, reflection, and other related (...) themes. I conclude with a suggestion about "the fundamental method" of phenomenology, free fantasy variation. (shrink)

Ethics and the Clinical Encounter explores the moral dimensions of clinical medicine and the phenomenon of illness, to determine what ethics must be in order to be fully responsive to clinical encounters. Written in a lively and conversational style with minimal technical terminology, and enhanced by actual experience or real clinical situations, this volume lays out a clinical ethics methodology both in practical and theoretical terms. Here's what the experts had to say: Professor Zaner has provided us with a remarkably (...) lucid and trenchant discussion of the interface of philosophy and the field of medicine. He brings into play an extraordinary range of historial knowledge, extensive observations based on firsthand experience with medical practices, and an acute sense of philosophical argumentation. This is a work that will be an exemplary and indispensable text in the philosophy of medicine for years to come. -- Calvin Schrag... it is a highly original contribution usable in a number of fields.... It really has no competition.... The genius of Zaner's approach is to ground ethics from the 'bottom up' and to direct us to the concrete particulars of therapeutic encounters wherein lie moral and ethical matters... meaty, challenging, and ultimately rewarding.... -- Paul R. Dokecki Richard M. Zaner founded the Center for Clinical and Research Ethics at Vanderbilt University Medical Center. Having established Vanderbilt's first Hospital Ethics Committee (1985), he served as co-chair of VUMC's Ethics Committee since its inception in 1990. Zaner has published five original books, edited ten, and translated four more, and has published more than 100 sections of books and professional journals. (shrink)

After expressing gratitude to each contributor, and briefly commenting on each, I probe several main themes of my work, addressing the question of the apparent difference between my earlier philosophical and later clinical writings. Central to both is the reflexivity of the human agent, and that each exhibits a form of practice regardless of the specific aims embedded in each. I then address the theme of narrative writing as my work has developed over the past several decades – at the (...) heart of which are questions of self and integrity. (shrink)

Tested the 2-process theory of detection, search, and attention presented by the current authors in a series of experiments. The studies demonstrate the qualitative difference between 2 modes of information processing: automatic detection and controlled search; trace the course of the learning of automatic detection, of categories, and of automatic-attention responses; and show the dependence of automatic detection on attending responses and demonstrate how such responses interrupt controlled processing and interfere with the focusing of attention. The learning of categories is (...) shown to improve controlled search performance. A general framework for human information processing is proposed. The framework emphasizes the roles of automatic and controlled processing. The theory is compared to and contrasted with extant models of search and attention. (shrink)

In what has become a classic work, Richard M. Weaver unsparingly diagnoses the ills of our age and offers a realistic remedy. He asserts that the world is intelligible, and that man is free. The catastrophes of our age are the product not of necessity but of unintelligent choice. A cure, he submits, is possible. It lies in the right use of man's reason, in the renewed acceptance of an absolute reality, and in the recognition that ideas—like actions—have consequences.

The measurement of sensory intensity has had a long history, attracting the attention of investigators from many disciplines including physiology, psychology, physics, mathematics, philosophy, and even chemistry. While there has been a continuing doubt by some that sensation has the properties necessary for measurement, experiments designed to obtain estimates of sensory intensity have found that a general rule applies: Equal stimulus ratios produce equal sensory ratios. Theories concerning the basis for this simple psychophysical rule are discussed, with emphasis given to (...) the physical correlate theory, which considers judgments of subjective magnitudes to be based upon estimates of physical dimensions that vary regularly with changes in degree of stimulation. For the most thoroughly investigated sensory scales, brightness and loudness, the physical correlate is considered to be distance. Our “tacit knowledge” of the sensory effects of changing distance plays an essential role in matching motor activities to environmental conditions and in ensuring accurate perceptual evaluations through brightness and loudness constancies. In psychophysical experiments, subjects apparently use this same tacit knowledge when required to estimate relative subjective magnitudes. The evidence related to the physical correlate theory is summarized, and it is concluded that, while under appropriate conditions we demonstrate considerable skill in evaluating environmental relationships, we are quite unable to estimate the neurophysiological nature or quantity of sensory response. A psychophysics devoted to studying conditions required for accuracy and conditions producing errors in the perception of environmental relationships would seem to be more valuable than one devoted to subjective magnitudes.

Objectivity in the sciences is a much-touted yet problematic concept. It is sometimes held up as characterising scientific knowledge, yet operational definitions are diverse and call for such paradoxical genius as the ability to see without a perspective, to predict repeatability, to elicit nature’s own self-revelation, or to discern the structure of reality with inerrancy. Here we propose a positive and general definition of objectivity based on work in the Reformational philosophy tradition. We recognise a suite of relation-frames–ways in which (...) things function and relate to each other, which can be analytically distinguished in the process of conceptual abstraction. These relation-frames also ground the diverse aspects of scientific analysis within which relationships and properties may be abstracted from entities and systems. We argue that objectivity can be understood as characteristic of representations that attempt to portray a subject in an earlier relation-frame than that in which it characteristically functions. In short, objectivity is projection. This proposal is exemplified from mathematics and the natural sciences and some possible objections to it are considered, as well as its extension to the social sciences. (shrink)

Early in the first volume of his Ideen zu einer reinen Phiinomeno logie und phiinomenologischen Philosophie, Edmund Husserl stated concisely the significance and scope of the problem with which this present study is concerned. When we reflect on how it is that consciousness, which is itself absolute in relation to the world, can yet take on the character of transcendence, how it can become mundanized, We see straightaway that it can do that only by means of a certain participation in (...) transcendence in the first, originary sense, which is manifestly the transcendence of material Nature. Only by means of the experiential relation to the animate organism does consciousness become really human and animal (tierischen), and only thereby does it achieve a place in the space and in the time of Nature. l Consciousness can become "worldly" only by being embodied within the world as part of it. In so far as the world is material Nature, consciousness must partake of the transcendence of material Nature. That is to say, its transcendence is manifestly an embodiment in a material, corporeal body. Consciousness, thus, takes on the characteristic of being "here and now" (ecceity) by means of experiential (or, more accurately, its intentive) relation to that corporeal being which embodies it. Accordingly, that there is a world for consciousness is a conse quence in the first instance of its embodiment by 2 that corporeal body which is for it its own animate organism. (shrink)
