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.

Hand function improvement in stroke survivors in the chronic stage usually plateaus by 6 months. Brain-computer interface (BCI)-guided robot-assisted training has been shown to be effective for facilitating upper-limb motor function recovery in chronic stroke. However, the underlying neuroplasticity change is not well understood. This study aimed to investigate the whole-brain neuroplasticity changes after 20-session BCI-guided robot hand training, and whether the changes could be maintained at the 6-month follow-up. Therefore, the clinical improvement and the neurological changes before, immediately after, (...) and 6 months after training were explored in 14 chronic stroke subjects. The upper-limb motor function was assessed by Action Research Arm Test (ARAT) and Fugl-Meyer Assessment for Upper-Limb (FMA), and the neurological changes were assessed using resting-state functional magnetic resonance imaging. Repeated-measure ANOVAs indicated that long-term motor improvement was found by both FMA (F[2,26]= 6.367,p= 0.006) and ARAT (F[2,26]= 7.230,p= 0.003). Seed-based functional connectivity analysis exhibited that significantly modulated FC was observed between ipsilesional motor regions (primary motor cortex and supplementary motor area) and contralesional areas (supplementary motor area, premotor cortex, and superior parietal lobule), and the effects were sustained after 6 months. The fALFF analysis showed that local neuronal activities significantly increased in central, frontal and parietal regions, and the effects were also sustained after 6 months. Consistent results in FC and fALFF analyses demonstrated the increase of neural activities in sensorimotor and fronto-parietal regions, which were highly involved in the BCI-guided training.Clinical Trial Registration:This study has been registered atClinicalTrials.govwith clinical trial registration number NCT02323061.

Bioethical Prescriptions collects F.M. Kamm's articles on bioethics -- revised for publication in book form -- which have appeared over the last 25 years and which have made her among the most widely-respected philosophers working in this field.

In this volume, F.M. Kamm explores how theories as well as hypothetical and practical cases help us understand rights and their limits. The book begins by considering moral status and its relation to having rights (including whether non-human animals have rights and what rights future persons have). The author then considers whether rights are grounded in duties to oneself, which duties are correlative to rights, and whether neuroscientific and psychological studies can help determine what rights we have. Kamm next investigates (...) the contours of the right not to be harmed by considering critiques of deontological distinctions, the costs that must be undertaken to avoid harming, and a proposal for permissibly harming someone (that allows for resisting the harm) in the Trolley Problem. Additional chapters cover possible implications of the Trolley Problem for such practical issues as correctly programming self-driving cars, providing medical treatments, and enacting redistributive economic policy. Kamm concludes the book by comparing the use of case-based judgments about extreme cases in moral versus aesthetic theory, and by exploring the significance of the right not to be harmed for morally correct policies in the extreme cases of torture and a pandemic. Where pertinent, Kamm considers the views of Derek Parfit, Tom Regan, Christine Korsgaard, Shelly Kagan, Ronald Dworkin, Amartya Sen, Allan Gibbard, Joshua Greene, Arthur Danto, and Judith Thomson, among others."--Provided by publisher.

A detailed attempt to ground the topological properties of time in the laws of micro- and macro-physical processes. The reversible processes of mechanics are used to define an order among temporally separated events, which is invariant under reversals of time direction. So long as consideration is limited to a single isolated system, a time ensemble, the transfer of the reversibility of the constituent processes of such a system to the system as a whole makes it impossible to define time direction (...) by means of the entropy curve. The directionality of time, accordingly, can only be defined as the direction of the entropy increase of multiple systems, of a space ensemble. A macrostatistical definition of time direction is then based upon the causal relation. The author's view of causation is non-deterministic: the conjunction of two events is caused if they occur together more frequently than can be expected from their chance coincidence. Reichenbach's analyses and arguments are careful and thorough; the book as a whole is a solid achievement. -- M. F. (shrink)

This essay argues that the Putnam-Nussbaum thesis that modern functionalism is Aristotelian is false. It fails as an interpretation of Aristotle since it fails to notice that Aristotle’s conception of the material or physical side of the soul-body relation is one which no modern functionalist could share. The Putnam-Nussbaum thesis is examined within the context of the theory of perception. This involves the need to understand one of the most mysterious Aristotelian doctrines – the doctrine that in perception, the sense-organ (...) assumes the sensible form of the object perceived without its matter.

This book traces the history of philosophy in Great Britain from the time when it began to be written until the end of the Victorian era. A valuable feature is the extensive bibliography, which was revised especially for the first printing of this 1965 back edition.

This book has been considered by academicians and scholars of great significance and value to literature. This forms a part of the knowledge base for future generations. So that the book is never forgotten we have represented this book in a print format as the same form as it was originally first published. Hence any marks or annotations seen are left intentionally to preserve its true nature.

This book is a collection of 18 essays portraying a "humanistic" outlook on several contemporary moral problems, and includes such essayists as Kurt Baier, Carl Rogers, B. F. Skinner, Sidney Hook, Abraham Edel, John Somerville, and Corliss Lamont. Although each was requested first to give his own definition of humanism and then to work out one application of it from his particular field or interest, these directions are not always strictly adhered to. Half of the essays had in fact, already (...) been published in some form in The Humanist. The 5 topical headings of the book show the diversity of fields and interests portrayed: Ethics, Religion and the Meaning of Life; The Good Life; The Individual: Law, Morality and Social Organization; Justice and Society; and Death. Although the essays are of unequal philosophical depth and acumen, this variety may be appealing for some uses of this as a text. However, two of the essays in particular stand out for this reviewer: "Ethics Without Religion" by Kai Nielsen, which perceptively outlines the problematic for as well as against an ethics not rooted in religion, and "The Enforcement of Morals" by Ernest Nagel which aptly analyzes the problem of the relation between the spheres of morality and law taking as a focus the noted Hart-Devlin debate of this issue. The thread which Kurtz believes unites all of these essays is their portrayal of a humanistic viewpoint, a viewpoint which he attempts to summarize in his own 14-page introduction, "What is Humanism?" But defining humanism is not an easy task. One must steer between a strictly negative view which defines it only in relation to what it opposes, and a broader but rather indefinite view of it as some form of man-centered philosophy. Although Kurtz wants to be positive in his own definition, he seems unable to move away from a negative and rhetorical presentation in which theism is simply stated to be incompatible with humanism. Moreover, his outline of a humanistic ethics is somewhat superficial. For example, he seems unaware of the problems involved in holding that ethical values are man’s own "creation" and at the same time are normative and objective. Nevertheless, the book may be of some help as a supplementary text to stimulate undergraduate students in discussion and study of the topics treated therein.—B.A.M. (shrink)

The Moral Target: Aiming at Right Conduct in War and Other Conflicts comprises essays that discuss aspects of war and other conflicts in the light of nonconsequentialist ethical theory. Topics include the relation between conditions that justify starting war and those that justify stopping it, the treatment of combatants and noncombatants in war, collaboration, justice after war and other conflicts, terrorism, resistance to communal injustice, and nuclear deterrence.

L'A. intende negare che l'opera conosciuta nella tradizione islamica, nel medioevo e nel Rinascimento come De intellectu sia attribuibile, come comunemente viene ritenuto, ad Alessandro di Afrodisia. Attraverso l'esame di un passaggio sull'analogia fra la luce e l'Uno, l'A. dimostra l'influenza plotiniana e alessandrina del testo, che risalirebbe alla tarda tradizione neoplatonica dei commentari ad Aristotele.
