What are mental images? Traditionally, philosophers have taken them to be representations of a certain kind. In common with all representations, they are seen as the kinds of thing that can be coloured, noisy, odorous, palpable or tasty, depending upon what they are representations of. But, in The Concept of Mind, Professor Ryle argues that this view of mental imagery is incoherent. Anything, he says, that really is coloured or noisy and so on, must, in principle, be locatable, which mental (...) images are not. He concludes that they cannot be the kinds of thing that the traditional view asserts them to be. Indeed, he goes further: he maintains that everything that exists has at least one of the properties mentioned in the above list and that, since mental images fail in this regard, they do not exist.Unfortunately, Professor Ryle's arguments in support of his contention that mental images are unlocatable are not conclusive. He assumes that if one can show that mental images are not locatable in ordinary space, they are not locatable in principle. (shrink)

Among the objections to the implementation of what I will call "genome editing in human reproduction" is that it does not address any unmet medical need, and therefore fails to meet an important criterion for introducing an unproven procedure with potentially adverse consequences. To be clear: what I mean by GEHR is the use of any one of a number of related biological techniques, such as the CRISPR-Cas9 system, deliberately to modify a functional sequence of DNA in a cell of (...) a human embryo, so that the modified sequence is replicated in the cells of a resulting child and may, without further intervention, be passed on to that child's biological descendants. It is... (shrink)

It is immensely difficult to give a philosophically adequate account of mental imagery. Peter F.R. Haynes, pp. 709–19) objects to the standard accounts, and offers one of his own which avoids the standard difficulties. Unfortunately it in turn seems to lapse into incoherence.Haynes rejects Cartesian accounts which would make images private objects in non-physical space. He also rejects current alternative views: both Rylean or behaviourist ones; and also intentionally complex ones, which assert that the relevant terms change (...) their meaning. He thinks that J. J. C. Smart's “topic neutral” approach may supply “the basis for a correct, intentionally simple, intuitively satisfying account of mental imagery”. But an adequate account must also be neutral, as Smart's is not, between different theories of mind. In addition to avoiding these difficulties an adequate theory has certain other desiderata; in particular Haynes places valuable emphasis on the need to explain the fact that we can sometimes mistake images for real perceptions or, more real perceptions for images.

The current implementation of the Neo-Darwinian model of evolution typically assumes that the set of possible phenotypes is organized into a highly symmetric and regular space. Most conveniently, a Euclidean vector space is used, representing phenotypic properties by real-valued variables. Computational work on the biophysical genotype-phenotype model of RNA folding, however, suggests a rather different picture. If phenotypes are organized according to genetic accessibility, the resulting space lacks a metric and can be formalized only in terms of a relatively unfamiliar (...) structure. Patterns of phenotypic evolution—such as punctuation, irreversibility, and modularity—result naturally from the properties of the genotype-phenotype map, which, given the genetic accessibility structure, define accessibility in the phenotype space. The classical framework, however, addresses these patterns exclusively in terms of natural selection on suitably constructed fitness landscapes. Recent work has extended the explanatory level for phenotypic evolution from fitness considerations alone to include the topological structure of phenotype space as induced by the genotype-phenotype map. Lewontin’s notion of “quasi-independence” of characters can also be formalized in topological terms: it corresponds to the assumption that a region of the phenotype space is represented by a product space of orthogonal factors. In this picture, each character corresponds to a factor of a region of the phenotype space. We consider any region of the phenotype space that has a given factorization as a “type”, i.e., as a set of phenotypes that share the same set of phenotypic characters. Thus, a theory of character identity can be developed that is based on the correspondence of local factors in different regions of the phenotype space. (shrink)

John Stuart Mill's Utilitarianism continues to serve as a rich source of moral and theoretical insight. This collection of articles by top scholars offers fresh interpretations of Mill's ideas about happiness, moral obligation, justice, and rights. Applying contemporary philosophical insights, the articles challenge the conventional readings of Mill, and, in the process, contribute to a deeper understanding of utilitarian theory as well as the complexity of moral life.

This volume critically and constructively discusses philosophical questions which have particular bearing on the formulation of educational aims. The book is divided into three major parts: the first deals with the nature of education, and discusses the various general aims, such as 'mental health', 'socialization' and 'creativity' which have been thought to characterize it; the second section is concerned with the nature of reason and its relationship to feeling, will and action; finally the development of different aspects of reason in (...) an educational context is considered.

While several tests and strategies are recommended for colorectal cancer (CRC) screening, studies suggest that primary care providers often recommend colonoscopy without providing information about its risks or alternatives. These observations raise concerns about the quality of informed consent for screening colonoscopy.

This study is concerned with processes for discovering new theories in science. It considers a computational approach to scientific discovery, as applied to the discovery of theories in cognitive science. The approach combines two ideas. First, a process-based scientific theory can be represented as a computer program. Second, an evolutionary computational method, genetic programming, allows computer programs to be improved through a process of computational trialand-error. Putting these two ideas together leads to a system that can automatically generate and improve (...) scientific theories. The application of this method to the discovery of theories in cognitive science is examined. Theories are built up from primitive operators. These are contained in a theory language that defines the space of possible theories. An example of a theory generated by this method is described. These results support the idea that scientific discovery can be achieved through a heuristic search process, even for theories involving a sequence of steps. However, this computational approach to scientific discovery does not eliminate the need for human input. Human judgment is needed to make reasonable prior assumptions about the characteristics of operators used in the theory generation process, and to interpret and provide context for the computationally generated theories.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

This article will begin by examining the extent to which R. S. Peters merited the charge of analytic philosopher. His background in social psychology allowed him to become more pragmatic and grounded in social conventions and ordinary language than the analytic philosophers associated with empiricism, and his gradual shift from requiring internal consistency to developing a notion of ?reasonableness?, in which reason could be tied to passion, grounded him in an idiosyncratic notion of ethics which included compassion and virtue as (...) well as reason. I describe his position on ethics as a systemic one of principled pragmatism. (shrink)

Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

It has come to be expected that collections issued by the Royal Institute of Philosophy will contain work that has quality or is otherwise interesting. This volume runs true to form and presents plenty of both. It gives the proceedings of the conference arranged by the Institute at Exeter in 1973, consisting of five symposia together with Chairman's remarks of about eight pages or so for each symposium, and in three cases postscripts by the first speaker. The contributors and topics (...) are: R. F. Dearden and Elizabeth Telfer on ‘Autonomy as an Educational Ideal’ with R. M. Hare as Chairman; R. K. Elliott and Glenn Langford on ‘Education and the Development of the Understanding’ with Paul Hirst as Chairman; David Cooper and Timothy O'Hagan on ‘Quality and Equality in Education’ with R. F. Atkinson as Chairman; Mary Warnock and Richard Norman on ‘The Neutral Teacher’ with Alan Montefiore as Chairman; Stuart Brown and A. Phillips Griffiths on ‘Academic Freedom’ with R. S. Peters as Chairman. (shrink)

Presents a plethora of approaches to developing human potential in areas not conventionally addressed. Organized in two parts, this international collection of essays provides viable educational alternatives to those currently holding sway in an era of high-stakes accountability.

For forty years, Harvey Mansfield has been worth reading. Whether plumbing the depths of MachiavelliOs Discourses or explaining what was at stake in Bill ClintonOs impeachment, MansfieldOs work in political philosophy and political science has set the standard. In Educating the Prince, twenty-one of his students, themselves distinguished scholars, try to live up to that standard. Their essays offer penetrating analyses of Machiavellianism, liberalism, and America., all of them informed by MansfieldOs own work. The volume also includes a bibliography of (...) MansfieldOs writings. (shrink)

This rich and varied collection of essays addresses some of the most fundamental human questions through the lenses of philosophy, literature, religion, politics, and theology. Peter Augustine Lawler and Dale McConkey have fashioned an interdisciplinary consideration of such perennial and enduring issues as the relationship between nature and history, nature and grace, reason and revelation, classical philosophy and Christianity, modernity and postmodernity, repentance and self-limitation, and philosophy and politics.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories (...) and On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)
