A set X of nonnegative integers is computably enumerable (c.e.), also called recursively enumerable (r.e.), if there is a computable method to list its elements. Let ε denote the structure of the computably enumerable sets under inclusion, $\varepsilon = (\{W_e\}_{e\in \omega}, \subseteq)$ . We previously exhibited a first order ε-definable property Q(X) such that Q(X) guarantees that X is not Turing complete (i.e., does not code complete information about c.e. sets). Here we show first that Q(X) implies that X has (...) a certain "slowness" property whereby the elements must enter X slowly (under a certain precise complexity measure of speed of computation) even though X may have high information content. Second we prove that every X with this slowness property is computable in some member of any nontrivial orbit, namely for any noncomputable A ∈ ε there exists B in the orbit of A such that X ≤ T B under relative Turing computability (≤ T ). We produce B using the Δ 0 3 -automorphism method we introduced earlier. (shrink)

“Tell me," Wittgenstein once asked a friend, "why do people always say, it was natural for man to assume that the sun went round the earth rather than that the earth was rotating?" His friend replied, "Well, obviously because it just looks as though the Sun is going round the Earth." Wittgenstein replied, "Well, what would it have looked like if it had looked as though the Earth was rotating?” What would it have looked like if we looked at all (...) sciences from the viewpoint of Wittgenstein’s philosophy? Wittgenstein is undoubtedly one of the most influential philosophers of the twentieth century. His complex body of work has been analysed by numerous scholars, from mathematicians and physicists, to philosophers, linguists, and beyond. This volume brings together some of his central perspectives as applied to the modern sciences and studies the influence they may have on the thought processes underlying science and on the world view it engenders. The contributions stem from leading scholars in philosophy, mathematics, physics, economics, psychology and human sciences; all of them have written in an accessible style that demands little specialist knowledge, whilst clearly portraying and discussing the deep issues at hand.

The problem that confronts us when we try to compare the structure of discourse and explanation in different domains of knowledge is that no one is an insider in more than one field, and insider information is essential. An observer who is not immersed in the practice of a particular scholarship and who wants to understand it is at the mercy of the practitioners. Yet those practitioners are themselves mystified by a largely unexamined communal myth of how scholarship is carried (...) on. R. G. Collingwood, although primarily a philosopher, was immersed in the community of historians and understood how history is done, so that he has had an immense influence on our ideas about historiography. Every historian knows The Idea of History.1 He was also a metaphysician, yet his influence on scientists’ understanding of nature, and of science, has been nil, and it is a rare scientist indeed who has ever heard of Collingwood or read The Idea of Nature.2 Collingwood’s views of the structure of science had to be constructed in large part from the elaborate fictions created by scientists and by an earlier generation of philosophers and historians of science who participated in the Baconian myth of the hypothetical-deductive scheme. 1.

He is an experimental and theoretical evolutionary geneticist who has also worked extensively on epistemological issues in biology.

Objective—To report the ethical development of medical students across four years of education at one medical school.Design and setting—A questionnaire was distributed to all four classes at the Wake Forest University School of Medicine during the Spring of 1996. Participants—Three hundred and three students provided demographic information as well as information concerning their ethical development both as current medical students and future interns. Main measurements—Results were analyzed using cross-tabulations, correlations, and analysis of variance.Results—Results suggested that the observation of and participation (...) in unethical conduct1 may have disparaging effects on medical students' codes of ethics with 35% of the total sample (24% of first years rising to 55% of fourth years) stating that derogatory comments made by residents/attendings, either in the patient's presence or absence, were “sometimes” or “often” appropriate. However, approximately 70% of the sample contended that their personal code of ethics had not changed since beginning medical school and would not change as a resident. Conclusions—Results may represent an internal struggle that detracts from the medical school experience, both as a person and as a doctor. Our goal as educators is to alter the educational environment so that acceptance of such behaviour is not considered part of becoming a physician. (shrink)

This article explores the emergence of standards and regulation associated with the provision of Closed Circuit Television (CCTV) surveillance systems in the United Kingdom. It argues that despite the intrusive and controlling nature of CCTV technology there is limited formal intervention in the form of legislation, governing its introduction and use. Instead government has sought to influence the regulation of the technology indirectly through its ability to shape and govern policy networks in the policy arena. In doing so, it is (...) argued here, that government remains the dominant actor in the policy process. (shrink)

Chalmers (2018) maintains that even if we understood every physical process in the brain we could still wonder why these processes give rise to conscious experience. The meta-problem is the challenge of explaining why we think this 'hard problem' exists. This response to the target paper endorses illusionist accounts of three 'problem intuitions' about consciousness: duality, presentation, and revelation. Subject–object duality is explained in terms of a clash between two compelling but contradictory convictions about consciousness. Phenomenal presence is understood in (...) relation to the configurational features of sensory experiences. And intuitions of revelation are explained as due to an unfounded belief in introspective ontological access. These illusionist analyses are used to bolster the case for physicalist realism rather than to support 'strong' illusionism. In addition to addressing the meta-problem they suggest a promising approach to the hard problem as wel. (shrink)

Hawthorne and Magidor's criticisms of the model of presupposition and assertion that I have used and defended are all based on a rejection of some transparency or introspection of assumptions about speaker presupposition. This response to those criticisms aims first to clarify, and then to defend, the required transparency assumptions. It is argued, first, that if the assumptions are properly understood, some prima facie problems for them do not apply, second, that rejecting the assumptions has intuitively implausible consequences, and third, (...) that the 'margin of error' argument against the principle of positive introspection has a false premiss. The paper concludes with a response to a criticism of what Hawthorne and Magidor call 'the uniformity principle' that is used in the model to explain some pragmatic phenomena. (shrink)

Biologically motivated computing seeks to transfer ideas from the biosciences to computer science. In seeking to make transfers it is helpful to be able to appreciate the metaphors which people use. This is because metaphors provide the context through which analogies and similes are made and by which many scientific models are constructed. As such, it is important for any rapidly evolving domain of knowledge to have developments accounted for in these terms. This paper seeks to provide one overview of (...) the process of modelling and shows how it can be used to account for a variety of biologically motivated computational models. Certain key ideas are identified in the subsequent analysis of biological sources, notably, systemic metaphors. Three important aspects of biological thinking are then considered in the light of computer science applications: biological organization, the cell, and models of evolution. The analysis throughout the paper is descriptive rather than formalized so that a large variety of potential applications may be considered. (shrink)

In numerous texts Leibniz claimed that while metaphysical necessity is inconsistent with free choice, moral necessity is not. A question naturally arises concerning what Leibniz took moral necessity to be. In a series of recent articles Michael Murray has argued that the concept of moral necessity Leibniz utilized is one developed and deployed by a group of 17th century Spanish Jesuits. This chapter argues that Leibniz's commitment to certain deep metaphysical principles suggests otherwise.
