Essays discuss cognition, perception, art, science, truth, metaphor, education, philosophy, and cognitive psychology.

How Classification Works attempts to bridge the gap between philosophy and the social sciences using as a focus some of the work of Nelson Goodman. Throughout his long career Goodman has addressed the question: are some ways of conceptualizing more natural than others? This book looks at the rightness of categories, assessing Goodman's role in modern philosophy and explaining some of his ideas on the relation between aesthetics and cognitive theory. Two papers by Nelson Goodman are included in (...) the collection and there are analyses of his work by seven leading academics in anthropology, philosophy, sociology and musicology. (shrink)

Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety of data on capacity limits suggesting that the smaller capacity limit is real. Capacity limits (...) will be useful in analyses of information processing only if the boundary conditions for observing them can be carefully described. Four basic conditions in which chunks can be identified and capacity limits can accordingly be observed are: (1) when information overload limits chunks to individual stimulus items, (2) when other steps are taken specifically to block the recoding of stimulus items into larger chunks, (3) in performance discontinuities caused by the capacity limit, and (4) in various indirect effects of the capacity limit. Under these conditions, rehearsal and long-term memory cannot be used to combine stimulus items into chunks of an unknown size; nor can storage mechanisms that are not capacity-limited, such as sensory memory, allow the capacity-limited storage mechanism to be refilled during recall. A single, central capacity limit averaging about four chunks is implicated along with other, noncapacity-limited sources. The pure STM capacity limit expressed in chunks is distinguished from compound STM limits obtained when the number of separately held chunks is unclear. Reasons why pure capacity estimates fall within a narrow range are discussed and a capacity limit for the focus of attention is proposed. Key Words: attention; enumeration; information chunks; memory capacity; processing capacity; processing channels; serial recall; short-term memory; storage capacity; verbal recall; working memory capacity.

In his new foreword to this edition, Hilary Putnam forcefully rejects these nativist claims.

. . . Unlike Dewey, he has provided detailed incisive argumentation, and has shown just where the dogmas and dualisms break down." -- Richard Rorty, The Yale Review.

Biobanks are currently archiving human materials for medical research at a hitherto unprecedented rate. These valuable resources will be essential for developing ‘personalized’ medicines and for a better understanding of disease susceptibilities. However, for such scientific advances to benefit everyone, it is crucial that biobanks recruit donations from all sections of the community. Unfortunately, other initiatives, such as transplant programmes, have clearly demonstrated that ethnic minorities are under-represented. Here we suggest that this issue deserves serious consideration to avoid biobanks evolving (...) into ethnically biased archives which unwittingly promote race-specific research. Specifically, this necessitates research ethics committees engaging in a re-assessment of the relative merits of individual personal sovereignty and the common good. (shrink)

With this third edition of Nelson Goodman's The Structure of Appear ance, we are pleased to make available once more one of the most in fluential and important works in the philosophy of our times. Professor Geoffrey Hellman's introduction gives a sustained analysis and appreciation of the major themes and the thrust of the book, as well as an account of the ways in which many of Goodman's problems and projects have been picked up and developed by others. Hellman (...) also suggests how The Structure of Appearance introduces issues which Goodman later continues in his essays and in the Languages of Art. There remains the task of understanding Good man's project as a whole; to see the deep continuities of his thought, as it ranges from logic to epistemology, to science and art; to see it therefore as a complex yet coherent theory of human cognition and practice. What we can only hope to suggest, in this note, is the b. road Significance of Goodman's apparently technical work for philosophers, scientists and humanists. One may say of Nelson Goodman that his bite is worse than his bark. Behind what appears as a cool and methodical analysis of the conditions of the construction of systems, there lurks a radical and disturbing thesis: that the world is, in itself, no more one way than another, nor are we. It depends on the ways in which we take it, and on what we do. (shrink)

This book is a philosophical exploration of the theoretical causes behind the collapse of classical cybernetics. Alcibiades Malapi-Nelson advances the idea that the cybernetic understanding of the nature of a machine entails ontological and epistemological consequences that create both material and theoretical conundrums. He proposes that, given our current state of materials, research, and practices, there might be a way for cybernetics to flourish. The book starts with a historical treatment of cybernetics, and proceeds with a philosophical explanation of (...) its collapse-emphasizing the work of Turing, Ashby and von Neumann-and connects it with the emerging technologies carrying its signature. The transhumanist metaphysics of both cybernetics and NBIC is then unveiled. Finally, avenues of research that may allow these technologies to circumvent the cybernetic fate are indicated. It is advanced that emerging technologies ultimately entail an affirmation of humanity. (shrink)

How much bacterial evolution occurs in our intestines and which factors control it are currently burning questions. The formation of new ecotypes, some of which capable of coexisting for long periods of time, is highly likely in our guts. Horizontal gene transfer driven by temperate phages that can perform lysogeny is also widespread in mammalian intestines. Yet, the roles of mutation and especially lysogeny as key drivers of gut bacterial adaptation remain poorly understood. The mammalian gut contains hundreds of bacterial (...) species, each with many strains and ecotypes, whose abundance varies along the lifetime of a host. A continuous high input of mutations and horizontal gene transfer events mediated by temperate phages drives that diversity. Future experiments to study the interaction between mutations that cause adaptation in microbiomes and lysogenic events with different costs and benefits will be key to understand the dynamic microbiomes of mammals.

BackgroundThe return of genetics and genomics research results has been a subject of ongoing global debate. Such feedback is ethically desirable to update participants on research findings particularly those deemed clinically significant. Although there is limited literature, debate continues in African on what constitutes appropriate practice regarding the return of results for genetics and genomics research. This study explored perspectives and ethical considerations of Ugandan genomics researchers regarding the return of genetics and genomics research results.MethodsThis was a qualitative study that (...) employed in-depth interviews. Thirty participants were purposively selected based on their expertise as genomics researchers in Uganda. Data were analysed through content analysis along the main themes of the study using a comprehensive thematic matrix, to identify common patterns arising from the narratives. NVivo software 12 was used to support data analysis.ResultsThe return of genetics and genomics research results was generally acceptable to researchers, and some indicated that they had previously returned individual or aggregate results to participants and communities. The main reasons cited for sharing research results with participants included their clinical utility, actionability and overall benefit to society. Ethical considerations for appropriate return of results included a need for effective community engagement, genetic counselling prior to disclosure of the results, adequate informed consent, and proper assessment of the implications of, or consequences of returning of results. However, the approaches to return of results were perceived as unstandardized due to the lack of appropriate regulatory frameworks.ConclusionsThe return of genetic and genomic research results is generally acceptable to researchers despite the lack of appropriate regulatory frameworks. Ethical considerations for return of genetics and genomics research results are highly divergent, hence the need for national ethical guidelines to appropriately regulate the practice. (shrink)

What if human joy went on endlessly? Suppose, for example, that each human generation were followed by another, or that the Western religions are right when they teach that each human being lives eternally after death. If any such possibility is true in the actual world, then an agent might sometimes be so situated that more than one course of action would produce an infinite amount of utility. Deciding whether to have a child born this year rather than next is (...) a situation wherein an agent may face several alternatives whose effects could well ramify endlessly on such suppositions, for the child born this year would be a different person—one who preferred different things, performed different actions, and had different descendants—from a child born next year. It has recently been suggested that traditional utilitarianism stumbles on such cases of infinite utility. Specifically, utilitarianism seems to require, for its application, that all experience of pleasure and pain cease at some time in the future or asymptotically approach zero.2 If neither of these conditions holds, then the utility produced by each of two alternative actions may turn out to be infinite, and utilitarianism thus loses its ability to discriminate morally between them.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Meaning in Spinoza’s MethodAlan Nelson and Noa SheinAaron V. Garrett. Meaning in Spinoza’s Method. New York: Cambridge University Press, 2003. Pp. xii + 240. Cloth, $60.00.This is a book about some fundamental aspects of Spinoza's mature metaphysics. The principal focus is on Part I of the Ethics concerning infinite substance, and on Part V concerning the intuitive knowledge that is the goal of philosophy. Within this focus, (...) Garrett concentrates on Spinoza's method. Garrett explains how he has been influenced by interpretations that stress the structural parallel between the synthetic, geometrical presentation of the Ethics and the relations among the ideas of the well-ordered mind. The Ethics proceeds by deriving propositions concerning substance's modes from definitions of substance and related notions while the mind, insofar as it is free from emotions, intuitively knows things as following from God. Garrett's distinctive thesis, however, is that Spinozistic enlightenment depends on the process of emending the intellect as described in one of Spinoza's earliest works, the Treatise on the Emendation of the Intellect. While this work strongly foreshadows many of Spinoza's mature doctrines, its exposition much more closely resembles the analytic, non-geometric approach of Descartes's Meditations. Spinoza's therapy for the emendation of our "inadequate" ideas closely parallels Descartes's analytic therapy for making what he calls confused ideas "clear and distinct."Garrett is on firm ground in arguing that the process of enlightenment cannot be an unbroken chain of intuitive deductions. For one thing, the definitions and axioms printed in a copy of the Ethics are first sensed by the reader and are not likely to produce immediately the requisite adequate ideas (172). An example of one of Garrett's interesting conclusions is that the definition of God as consisting of an infinity of attributes, the sixth of Part I of the Ethics (1D6), is preliminary and replaced in the process of therapeutic emendation by a definition of God as self caused. It is only after our ideas have become adequate at the end of the process that we are able to fully appreciate 1D6 (171).One might think that Garrett does not go far enough here because his point can be naturally extended. Definitions might assist us in the process of bringing our adequate ideas to light, but our cognitive goal is making these ideas themselves adequate. What then are the ideas we can make most adequate and exactly what distinguishes them from highly refined ideas that are nevertheless more inadequate than these? On one interpretation it is divine essence, that is, the attributes of thought and extension that are individually most adequately conceived after successful therapy. It is tempting to suppose that a single idea of God as both thinking and extended would be more adequate still, but Spinoza holds that our conceptions of these attributes are "really distinct" in a sense analogous to Descartes's(1P10). Spinoza's 1D6 definition of God as a substance consisting of both these attributes (and perhaps other inconceivable ones) thus seems to indicate a subsumption of the attributes we can conceive under the image of some printed or spoken words. Such an idea would be more inadequate than our adequate conceptions of the individual attributes. One is here strongly reminded of Descartes's characterization in Article 63 of the first Part of his Principles of Philosophy, "... we more readily understand extended substance or thinking substance than substance alone."In his seventh and concluding chapter, Garrett tackles the grand problems of intuitive knowledge or knowledge of "the third kind" and the sense in which Spinoza thought a part of the human mind is eternal. The discussion is necessarily complex, but one great advantage of Garrett's treatment is that he realizes intuitive knowledge cannot consist in the explicit deduction of particular things from God. The detailed determination of particular "everyday objects" requires sensory knowledge which is, of course, never perfectly determinate and therefore inherently inadequate. But we can acquire the "second kind" of adequate knowledge by understanding what our minds have in common with other determinate, finite things. This finally enables us to ascend to an appreciation of these... (shrink)
