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.

This letter responds to the essay “Language Matters: The Semantics and Politics of ‘Assisted Dying,’” by Anna M. Elsner, Charlotte E. Frank, Marc Keller, Jordan O. McCullough, and Vanessa Rampton, in the September‐October 2024 issue of the Hastings Center Report.

Excerpt from The Psychological Aspects of Christian Experience Continued observation of the various methods of religious instruction has brought upon me a conviction that grows stronger as the years go by, that there must be, as Francis Peabody says, a new expansion of the range of studies appropri ate to the teachers of religion. There ought to be a far deeper study of the psychology of reli gion. The appeal to the impulses and emotions, so prevalent in the methods of (...) some teachers, is far behind twentieth century enlightenment. It was foreign to the methods of our Saviour. He taught men. He did not frighten them into ao tion, neither entice them. He instructed their minds in truth. Ye shall know the truth and the truth shall make you free.

We summarize several experiments indicating that the saccadic system is capable of simultaneously programming two movements toward different goals. This concurrent processing of saccades can lead to the execution of two saccades separated by an extremely short intersaccadic interval. This supports the idea of target competition proposed in Findlay & Walker's article, but suggests a greater degree of parallel processing. We provide evidence that concurrent processing of two saccades is not limited to higher-level planning subsystems; rather, it also involves both (...) regions close enough to the motor output that it can systematically affect saccade trajectory.

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)

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.

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)

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.

This book offers a powerful interpretation of the philosophy of William James. It focuses on the multiple directions in which James's philosophy moves and the inevitable contradictions that arise as a result. The first part of the book explores a range of James's doctrines in which he refuses to privilege any particular perspective: ethics, belief, free will, truth and meaning. The second part of the book turns to those doctrines where James privileges the perspective of mystical experience. Richard Gale (...) then shows how the relativistic tendencies can be reconciled with James's account of mystical experience. An appendix considers the distorted picture of James's philosophy that has been refracted down to us through the interpretations of his work by John Dewey. (shrink)

Philosophers of science turned to historical case studies in part in response to Thomas Kuhn's insistence that such studies can transform the philosophy of science. In this issue Joseph Pitt argues that the power of case studies to instruct us about scientific methodology and epistemology depends on prior philosophical commitments, without which case studies are not philosophically useful. Here I reply to Pitt, demonstrating that case studies, properly deployed, illustrate styles of scientific work and modes of argumentation that are not (...) well handled by currently standard philosophical analyses. I illustrate these claims with exemplary findings from case studies dealing with exploratory experimentation and with interdisciplinary cooperation across sciences to yield multiple independent means of access to theoretical entities. The latter cases provide examples of ways that scientists support claims about theoretical entities that are not available in work performed within a single discipline. They also illustrate means of correcting systematic biases that stem from the commitments of each discipline taken separately. These findings illustrate the transformative power of case study methods, allow us to escape from the horns of Pitt's "dilemma of case studies," and vindicate some of the post-Kuhn uses to which case studies have been put.

There has been in recent years a plethora of defences of theism from analytical philosophers: Richard Gale's important book is a critical response to these writings. New versions of cosmological, ontological, and religious experience arguments are critically evaluated, along with pragmatic arguments to justify faith on the grounds of its prudential or moral benefits. In considering arguments for and against the existence of God, Gale is able to clarify many important philosophical concepts including exploration, time, free will, personhood, actuality, (...) and the objectivity of experience.

We will give a new cosmological argument for the existence of a being who, although not proved to be the absolutely perfect God of the great Medieval theists, also is capable of playing the role in the lives of working theists of a being that is a suitable object of worship, adoration, love, respect, and obedience. Unlike the absolutely perfect God, the God whose necessary existence is established by our argument will not be shown to essentially have the divine perfections (...) of omnipotence, omniscience, omnibenevolence, and sovereignty. Furthermore, it is not even shown that he is contingently omnipotent and omniscient, just powerful and intelligent enough to be the supernatural designer-creator of the exceedingly complex and wondrous cosmos that in fact..

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)

This honest, forthright, and beautifully-written book introduces readers to the human variations on medical topics spoken of in abstract in the daily news--euthanasia, assisted suicide, abortion, "extreme procedures", genetic testing, experimental surgeries--and to the people who must agonize over those decisions regarding themselves and their loved ones.

History of science, it has been argued, has benefited philosophers of science primarily by forcing them into greater contact with "real science." In this paper I argue that additional major benefits arise from the importance of specifically historical considerations within philosophy of science. Loci for specifically historical investigations include: (1) making and evaluating rational reconstructions of particular theories and explanations, (2) estimating the degree of support earned by particular theories and theoretical claims, and (3) evaluating proposed philosophical norms for the (...) evaluation of the degree of support for theories and the worth of explanations. More generally, I argue that theories develop and change structure with time, that (like biological species) they are historical entities. Accordingly, both the identification and the evaluation of theories are essentially historical in character. (shrink)

This paper is devoted to an examination of the discovery, characterization, and analysis of the functions of microRNAs, which also serves as a vehicle for demonstrating the importance of exploratory experimentation in current (post-genomic) molecular biology. The material on microRNAs is important in its own right: it provides important insight into the extreme complexity of regulatory networks involving components made of DNA, RNA, and protein. These networks play a central role in regulating development of multicellular organisms and illustrate the importance (...) of epigenetic as well as genetic systems in evolution and development. The examination of these matters yields principled arguments for the historicity of the functions of key biological molecules and for the indispensability of exploratory experimentation in contemporary molecular biology as well as some insight into the complex interplay between exploratory experimentation and hypothesis-driven science. This latter result is not only important for philosophy of science, but also of practical importance for the evaluation of grant proposals, although the elaboration of this latter claim must be left for another occasion.

This article reviews current methods for evaluating models in the cognitive sciences, including theoretically based approaches, such as Bayes factors and minimum description length measures; simulation approaches, including model mimicry evaluations; and practical approaches, such as validation and generalization measures. This article argues that, although often useful in specific settings, most of these approaches are limited in their ability to give a general assessment of models. This article argues that hierarchical methods, generally, and hierarchical Bayesian methods, specifically, can provide a (...) more thorough evaluation of models in the cognitive sciences. This article presents two worked examples of hierarchical Bayesian analyses to demonstrate how the approach addresses key questions of descriptive adequacy, parameter interference, prediction, and generalization in principled and coherent ways.

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 essays in this collection examine developments in three fundamental biological disciplines--embryology, evolutionary biology, and genetics--in conflict with each other for much of the twentieth century. They consider key methodological problems and the difficulty of overcoming them. Richard Burian interweaves historical appreciation of the settings within which scientists work, substantial knowledge of the biological problems at stake and the methodological and philosophical issues faced in integrating biological knowledge drawn from disparate sources.

In what sense does time exist? Is it an objective feature of the external world? Or is its real nature dependent on the way man experiences it? Has modern science brought us closer to the answer to St. Augustine's exasperated outcry, 'What, then, is time?' ? Ever since Aristotle, thinkers have been struggling with this most confounding and elusive of philosophical questions. How long does the present moment last? Can we make statements about the future that are clearly true or (...) clearly false? And if so, must we be fatalists? This volume presents twenty-three discussions of the problem of time. A section on classical and modern attempts at definition is followed by four groups of essays drawn largely from contemporary philosophy, each preface with an introduction by the editor. First, in a chapter entitled 'The Static versus the Dynamic Temporal', four philosophers advance solutions to McTaggart's famous proof of time's unreality. In the next two sections, the discussion turns to the meaning of the 'open future' and to the much-debated nature of 'human time'. Finally, modern science and philosophy tackle Zeno's celebrated paradoxes. The essays by Adolf Grnbaum, Nicholas Rescher, and William Barrett are published for the first time in this volume.

Fiction has been of concern to both the aesthetician and the ontologist. The former is concerned with the criteria or standards by which we judge the aesthetic worth of a fictional work, the latter with whether our ontology must be enlarged to include possible or imaginary worlds in which are housed the characters and incidents referred to and depicted in such works. This is a paper on the ontology of fiction. It will attempt to answer these ontological questions concerning truth (...) and reference in fiction by clarifying the use of language. Our paradigm case of the fictive use of language will be one in which the story-teller orally relates the fictional story in the presence of his audience, rather than one in which he inscribes his story so that it may be read at a later date. The value of considering the use of language in a face-to-face situation is that it brings before us in their full explicitness all of the different facets of a speech act, many of which often lie dormant in non-face-to-face uses and therefore are hard to discover from a consideration of such uses.
