New success criteria of inductive inference in computational learning theory are introduced which model learning total (not necessarily recursive) functions with (possibly everywhere) imprecise theories from (possibly always) inaccurate data. It is proved that for any level of error allowable by the new success criteria, there exists a class of recursive functions such that not all f are identifiable via the criterion at that level of error. Also, necessary and sufficient conditions on the error level are given for when more (...) classes of functions may be identified. (shrink)

The hypothesis that there has been selection pressure for mechanisms which enable us to perceive the present tends to be conflated with the hypothesis that there has been selection pressure for mechanisms that compensate for inevitable neural delay. The relationship between the two is more subtle, because increases in neural delay can be advantageous for building more useful perceptions.

Evidence for instances of astrophysical 'fine tuning' (or 'coincidences') is thought by some to lend support to the design argument (i.e. the argument that our universe has been designed by some deity). We assess some of the relevant empirical and conceptual issues. We argue that astrophysical fine tuning calls for some explanation, but this explanation need not appeal to the design argument. A clear and strict separation of the issue of anthropic fine tuning on one hand and any form of (...) Eddingtonian numerology and teleology on the other, may help clarify arguably the most significant issue in the philosophy of cosmology. (shrink)

Weak emergence has been offered as an explication of the ubiquitous notion of emergence used in complexity science (Bedau 1997). After outlining the problem of emergence and comparing weak emergence with the two other main objectivist approaches to emergence, this paper explains a version of weak emergence and illustrates it with cellular automata. Then it explains the sort of downward causation and explanatory autonomy involved in weak emergence.

Hoerl & McCormack's theory defines temporal behavior from an awareness of time, but lacks one critical element: the impact of “psychological presence” in the “moment now.” Central to experience of temporal non-stationarity: “Nowness” links future with past in the context of time flow. Does this differ between species? Evidence suggests not: Different temporal experiences between species requires greater critical evaluation.

Child soldiers are generally perceived as faultless, passive victims. This ignores that the roles of child soldiers vary, from innocent abductee to wilful perpetrator. This book argues that child soldiers should be judged on their actions and that treating them like a homogenous group prevents them from taking responsibility for their acts.

An innocent form of emergence—what I call "weak emergence"—is now a commonplace in a thriving interdisciplinary nexus of scientific activity—sometimes called the "sciences of complexity"—that include connectionist modelling, non-linear dynamics (popularly known as "chaos" theory), and artificial life.1 After defining it, illustrating it in two contexts, and reviewing the available evidence, I conclude that the scientific and philosophical prospects for weak emergence are bright.

Teaching graduate students how to do research can be a challenge for many instructors because "research education" is not an established field of research like other areas of teaching such as mathematics education, nursing education, science education, and statistics education. There are no scholarly journals devoted solely to teaching research methods; these sources are instead scattered across disciplines and journals (e.g., Nurse Researcher, Volume 13, Number 2, 2005; Sociology, Volume 15, Issue 4, 1981; and Scandinavian Journal of Educational Research, Volume (...) 49, Issue 1, 2005). Furthermore, even though research methods courses are a staple in most graduate training programs, instructors were rarely taught how to teach research methods as part of their own graduate programs. Left to their own devices, instructors of research courses must rely on a network of peers, scattered research literature, and much trial-and-error as they develop and improve upon their own research methods courses.

Artificial life uses computer models to study the essential nature of the characteristic processes of complex adaptive systems proceses such as self-organization, adaptation, and evolution. Work in the field is guided by the working hypothesis that simple computer models can capture the essential nature of these processes. This hypothesis is illustrated by recent results with a simple population of computational agents whose sensorimotor functionality undergo open-ended adaptive evolution. These might illuminate three aspects of complex adaptive systems in general: punctuated equilibrium (...) dynamics of diversity, a transition separating genetic order and disorder, and a law of adaptive evolutionary activity.

This book explores the making of health care rationing decisions through the analysis of three alternative decision makers: patients paying out of pocket; officials setting limits on treatments and coverage; and physicians at the bedside. Hall develops this analysis along three dimensions: political economics, ethics, and law. The economic dimension addresses the practical feasibility of each method. The ethical dimension discusses the moral aspects of these methods, while the legal dimension traces the most recent developments in jurisprudence and health law.

The importance of preserving trust in physicians and in medical institutions has received widespread attention in recent years. Primarily, this is due to the threats to trust posed by managed care, but there is a general and growing recognition that trust deserves more attention than it traditionally has received in all aspects of medical ethics, law, and public policy. Trust has both intrinsic and instrumental value. Trust is intrinsically important because it is a core characteristic that affects the emotional and (...) interpersonal aspects of the physician/patient relationship. As an instrumental value, trust is widely believed to be essential for effective therapeutic encounters. It has been hypothesized or shown to affect a host of important behaviors and attitudes relating to care, including seeking care, disclosing private information, complying with treatment, and being satisfied with care. Moreover, trust may be a mediator of measurable clinical outcomes and a key factor in the mind–body interactions that underlie placebo/nocebo effects and the effectiveness of alternative medicine. It is no surprise, then, that preserving, justifying, and enhancing trust is the fundamental goal of much of medical ethics, and is a prominent objective in healthcare law and public policy. Discussions of trust and related concepts were commonplace in professionally based medical ethics prior to the 1970s. a 1 2. (shrink)

Dieser Aufsatz analysiert Leibniz' Begriff der Expression. Er ist eine Vorstudie zu einer umfassenden Untersuchung der Lehre, daß jede einfache Substanz das ganze Weltall ausdrückt.

The dynamical patterns in mental phenomena have a characteristic suppleness&emdash;a looseness or softness that persistently resists precise formulation&emdash;which apparently underlies the frame problem of artificial intelligence. This suppleness also undermines contemporary philosophical functionalist attempts to define mental capacities. Living systems display an analogous form of supple dynamics. However, the supple dynamics of living systems have been captured in recent artificial life models, due to the emergent architecture of those models. This suggests that analogous emergent models might be able to explain (...) supple dynamics of mental phenomena. These emergent models of the supple mind, if successful, would refashion the nature of contemporary functionalism in the philosophy of mind. (shrink)

In this paper, I offer a new solution to the old problem of how best to understand the meaning of the word ‘logos’ in the extant writings of Heraclitus, especially in fragments DK B1, B2 and B50. On the view I defend, Heraclitus was neither using the word in a perfectly ordinary way in these fragments, as some have maintained, nor denoting by it some kind of general principle or law governing change in the cosmos, as many have claimed. Rather, (...) I argue, Heraclitus deliberately traded on the ordinary use of the word in his time (to refer to a written or spoken presentation of things as ‘thus and so’) to denote the world’s constant presentation of itself as ‘thus and so’ to all of us in our experience – a kind of cosmic self-revelation. I show how this captures the sense in which ‘the logos’ is said to be ‘common’ (xunos) and to be the kind of thing most people fail to comprehend even before hearing Heraclitus’ own account, all without detaching Heraclitus’ use of the word from its ordinary contemporary meaning. This interpretation suggests Heraclitus was a thinker more centrally concerned with human (mis)understanding than with speculative cosmology. (shrink)

Weak emergence is the view that a system’s macro properties can be explained by its micro properties but only in an especially complicated way. This paper explains a version of weak emergence based on the notion of explanatory incompressibility and “crawling the causal web.” Then it examines three reasons why weak emergence might be thought to be just in the mind. The first reason is based on contrasting mere epistemological emergence with a form of ontological emergence that involves irreducible downward (...) causation. The second reason is based on the idea that attributions of emergence are always a reflection of our ignorance of non-emergent explanations. The third reason is based on the charge that complex explanations are anthropocentric. Rather than being just in the mind, weak emergence is seen to involve a distinctive kind of complex, macro-pattern in the mind-independent objective micro-causal structure that exists in nature. The paper ends by addressing two further questions. One concerns whether weak emergence applies only or mainly to computer simulations and computational systems. The other concerns the respect in which weak emergence is dynamic rather than static. (shrink)

The target article covers a large amount of ground and offers a provocative perspective. This commentary focuses on (a) assumptions, namely that there are discrete stages in the creative process and that novelty and usefulness are inextricable, (b) hidden variables in the creativity–curiosity relationship, and (c) the difference between an explanation of creativity versus a description of influence on it.

The sense of smell occupies a peculiar intermediate position within Aristotle's theory of sense perception: odours, like colours and sounds, are perceived at a distance through an external medium of air or water; yet in their nature they are intimately related to flavours, the proper objects of taste, which for Aristotle is a form of touch. In this paper, I examine Aristotle's claims about odour and smell, especially in De Anima II.9 and De Sensu 5, to see what light they (...) shed on his theory of sense perception more generally. In the first half, I argue that neither of the two most influential recent ways of understanding Aristotle's theory of perception can adequately account for what he says about the sense of smell. In the second half, I offer my own positive account, considering and resolving various puzzles raised by Aristotle's claims about the nature of odour and its relation to flavour. Finally, I conclude that Aristotle's discussions of odour and smell suggest a plausible and interesting way of understanding the relationship, on his view, between ordinary, material changes in the sense organs and the activation of the capacity to perceive, considered merely as such.

In De Anima II.6, Aristotle divides the objects of perception into three kinds: “special perceptibles" (idia aisthêta) such as colours, sounds and flavours, which can be perceived in their own right by only one sense; “common perceptibles" (koina aisthêta) such as shapes, sizes and movements, which can be perceived in their own right by multiple senses; and “incidental perceptibles,” such as the son of Diares, which can be perceived only “incidentally” (kata sumbebêkos). In this paper, I examine this division of (...) perceptibles and consider what it amounts to. First, I argue that Aristotle’s distinction between perceiving something in its own right (kath' hauto) and perceiving it incidentally marks a causal distinction: what is perceived in its own right causes perception as such, whereas what is perceived incidentally coincides with what is perceived in its own right. Second, I argue that for Aristotle special perceptibles, unlike common perceptibles, belong to homogeneous bodies on account of their chemical composition. Finally, I explain the primacy Aristotle assigns to special perceptibles and his claim that perception of them alone is free from error. I conclude with some brief remarks on Aristotle and the primary/secondary quality distinction. (shrink)

Wie geartet ist das Verhältnis zwischen den zentralen Begriffen „Bewußtsein“ und „Reflexion“ in Lockes Essay? Sind diese Begriffe für Locke identisch oder voneinander verschieden? Falls sie verschieden sind, wie ist der Unterschied genau zu bestimmen? Diese Arbeit untersucht die Fragen, unter Berücksichtigung der unterschiedlichen Deutungen in der Sekundärliteratur; sie sichtet und prüft den Text des Essays sorgfältig und breitet ein breites Spektrum philosophischer Implikationen von Lockes Ausführungen über das „Bewußtsein“ und „Reflexion“ aus. Der abschließende Teil legt dar, daß Locke niemals (...) eine feste Position gegenüber dem Verhältnis zwischen den beiden Begriffen eingenommen hat, sondern daß er zwischen verschiedenen Positionen schwankte -als Resultat der starken philosophischen Kräfte, die ihn bald in die eine, bald in die andere Richtung zogen.

Ligation is a form of chemical self-assembly that involves dynamic formation of strong covalent bonds in the presence of weak associative forces. We study an extremely simple form of ligation by means of a dissipative particle dynamics (DPD) model extended to include the dynamic making and breaking of strong bonds, which we term dynamically bonding dissipative particle dynamics (DDPD). Then we use a chemical genetic algorithm (CGA) to optimize the model’s parameters to achieve a limited form of ligation of trimers—a (...) proof of principle for the evolutionary design of self-assembling chemical systems.

Abstract:Moral imagination is a reasoning process thought to counter the organizational factors that corrupt ethical judgment. We describe the psychology of moral imagination as composed of the four decision processes identified by Rest (1986), i.e., moral sensitivity, moral judgment, moral intention, and moral behavior. We examine each process in depth, distilling extant psychological research and indicating organizational implications. The conclusion offers suggestions for future research.The majority of men are subjective toward themselves and objective toward all others—terribly objective sometimes—but the real (...) task is in fact to be objective toward one’s self and subjective toward all others.

Aristotle sometimes claims that the perception of special perceptibles by their proper sense is unerring. This claim is striking, since it might seem that we quite often misperceive things like colours, sounds and smells. Aristotle also claims that the perception of common perceptibles is more prone to error than the perception of special perceptibles. This is puzzling in its own right, and also places constraints on the interpretation of. I argue that reading Alexander of Aphrodisias on perceptual error can help (...) to make good sense of both of Aristotle’s claims. (shrink)

In this paper, I consider how each of the four main kinds of corrupt person described in Plato's Republic, Books 8-9, first comes to be. Certain passages in these books can give the impression that each person is able to determine, by a kind of rational choice, the overall government of his/her soul. However, I argue, this impression is mistaken. Upon careful examination, the text of books 8 and 9 overwhelmingly supports an alternative interpretation. According to this view, the eventual (...) government of each person’s soul is decided by a struggle for power occurring within the person, among the soul’s parts, the outcome of which is determined by the relative strength and alignment of the competing parties. If this interpretation is correct, Plato adheres more closely to the city-soul analogy in these passages than has sometimes been thought. The ultimate origins of vice in the soul are also seen to lie squarely in upbringing and education, not in a mistaken choice of life. (shrink)

Mobile devices with health apps, direct-to-consumer genetic testing, crowd-sourced information, and other data sources have enabled research by new classes of researchers. Independent researchers, citizen scientists, patient-directed researchers, self-experimenters, and others are not covered by federal research regulations because they are not recipients of federal financial assistance or conducting research in anticipation of a submission to the FDA for approval of a new drug or medical device. This article addresses the difficult policy challenge of promoting the welfare and interests of (...) research participants, as well as the public, in the absence of regulatory requirements and without discouraging independent, innovative scientific inquiry. The article recommends a series of measures, including education, consultation, transparency, self-governance, and regulation to strike the appropriate balance. (shrink)
