Addressing groups of industrial or academic experts goes with my job as editor in chief of Scientific American, and I enjoy it, but I confess that it inevitably feels peculiar. The audience consists of people who, almost by definition, have expertise or experience in the subjects of discussion. Why should anyone listen to me? I am a journalist—what do I know? a.

An accessible and groundbreaking text that takes a fresh view of contemporary geographical issues by looking at the geographies we have lost. Geography means writing about the world. Alternative ways of writing about the world are introduced and critically evaluated. The book discusses medieval cosmologies, Renaissance magic, feng shui, and the knowledge systems of indigenous people. Alternative Geographies provides an alternative way of looking, describing and understanding the world.

BackgroundIndividuals with early phase cognitive impairment are frequently affected by existential distress, social avoidance and associated health issues. The demand for efficient psychological support is crucial from both an individual and a societal perspective. We have developed a novel psychological intervention manual for providing a non-medical path to enhanced psychological health in the cognitively impaired population. The current article provides specific information on the randomized controlled trial -design and methods. The main hypothesis is that participants receiving PIPCI will increase their (...) psychological flexibility compared to participants in the active control group and the waiting list control group. The secondary hypotheses are that participants receiving PIPCI will improve psychological health compared to participants in the active control group and the waiting list control group.Materials and MethodsThis three-arm RCT will recruit participants from the cognitive centers at Karolinska University Hospital in Stockholm and randomize approximately 120 individuals in the early phase of cognitive impairment to either an experimental group, an active control group or a waiting list control group. Intervention outcome will be evaluated with self-report questionnaires on physical and psychological aspects of health, cognitive assessment, biological markers and health care costs. Assessments will be performed at pre- and post-intervention, as well as at a 6-month follow-up.DiscussionThe development of a potentially feasible and effective psychological intervention tailored for early phase cognitive impairment has the potential to advance the non-pharmacological intervention field. This is especially important given the extensive burden for many affected individuals and their families and the current lack of effective treatments. If the psychological intervention discussed here shows feasibility and efficacy, there is potential for far-reaching healthcare implications for patients with early cognitive impairment at risk of developing dementia.Clinical Trial RegistrationClinicalTrials.gov: NCT04356924.

This book continues and revises the ideas of justice as fairness that John Rawls presented in _A Theory of Justice_ but changes its philosophical interpretation in a fundamental way. That previous work assumed what Rawls calls a "well-ordered society," one that is stable and relatively homogenous in its basic moral beliefs and in which there is broad agreement about what constitutes the good life. Yet in modern democratic society a plurality of incompatible and irreconcilable doctrines--religious, philosophical, and moral--coexist within (...) the framework of democratic institutions. Recognizing this as a permanent condition of democracy, Rawls asks how a stable and just society of free and equal citizens can live in concord when divided by reasonable but incompatible doctrines? This edition includes the essay "The Idea of Public Reason Revisited," which outlines Rawls ' plans to revise _Political Liberalism,_ which were cut short by his death.

Over the past few years, a growing number of people have called for reconceptualizing participation in health research as a moral obligation. John Harris argues that seriously debilitating diseases give rise to important needs, and since medical research is necessary to relieve those needs in many circumstances, people are morally obligated to act as research subjects.1 Rosamond Rhodes claims that research participation is a moral obligation for reasons of justice, beneficence, and self-development: because we all benefit significantly from modern (...) medicine, we are all required to do our part in advancing the state of medical knowledge.2 Individuals who reap the benefits of medical knowledge without contributing ..

Abstract Drawing upon evolutionary theory and the work of Daniel Dennett and Nicholas Agar, I offer an argument for broadening discussion of the ethics of disenhancement beyond animal welfare concerns to a consideration of animal “biopreferences”. Short of rendering animals completely unconscious or decerebrate, it is reasonable to suggest that disenhanced animals will continue to have some preferences. To the extent that these preferences can be understood as what Agar refers to as “plausible naturalizations” for familiar moral concepts like (...) beliefs and desires, then they can make moral claims on us and provide support for intuitive opposition to disenhancement.

This volume has grown out of the international East Meets West Conferences established by Dr. Murthy, also the founder of Long Beach Publications. The stated object is “to stimulate a new debate between differing cultures and modes of thinking... [and] cross-cultural thinking which the global civilization now emerging needs”. Ninian Smart contributes the Preface and a short article, “The Comparative View of the Person: East and West,” which serves to set the tone of the volume. Although the article does (...) not attempt any final conclusion regarding the person, it brings to our notice the fact that “there are wildly diverse inner psychological vocabularies” and that the “Hindu views of the person... draw the line in a different place than do Western systems”. These divergences are “challenging and thought provoking,” and failure to consider them is “because of lingering tribalism, pervasively evident in our whole educational system,” says Smart. (shrink)

This chapter starts from the claim that the state is plagued with problems of political short-termism: excessive priority given to near-term benefits at the expense of benefits further in thefuture. One possible mechanism to reduce short-termism involves apportioning greater relative political influence to the young, since younger citizens generally have greater additional life expectancy than older citizens and thus it looks reasonable to expect that they have preferences that are extended further into the future. But the chapter shows (...) that this is unlikely to make states significantly less short-termist: no empirical relationship has been found between age and willingness to support long-termist policies. Instead, the chapter proposes a more promising age-based mechanism. States should develop youth citizens’ assemblies that ensure accountability to future generations through a scheme of retrospective accountability. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge History of Philosophy in Late AntiquityJohn RistLloyd P. Gerson, editor. The Cambridge History of Philosophy in Late Antiquity. 2 vols. Cambridge-New York: Cambridge University Press, 2010. Pp. 1313. Cloth, $240.00.1313 pages, including 915 pages of text and 200 of bibliography; 51 authors—in about 800 words! The editor of the present Cambridge History makes plain that his new two-volume monument is the successor to Armstrong’s Cambridge History (...) of Late Greek and Early Medieval Philosophy—8 contributors—and is intended to build on its strengths and correct its deficiencies in the light of some 40 years of highly successful investigation of the thought of late antiquity. The result is a professional structure in which the “giants” (Plotinus and Augustine) are awarded comparatively modest coverage, while figures often neglected, such as Damascius, of whom our understanding has greatly increased of late, are given much more space. Damascius secures 30 pages: the only individual to get more is Porphyry (33), while Augustine has 29 and Plotinus 24 (four more than Hierocles). There are those (as Tacitus might have put it) who will fear that the wood has been lost for the trees, and at least it must be said that one overall impression of these volumes is that some of their authors are recounting what will be of interest to a worldwide group of aficionados whose number can be counted on the fingers of a mutilated hand—and the importance of which lies less in philosophical achievement than in the handing on of a great tradition.Gilbert Ryle is supposed to have asserted that in France everyone can talk about philosophy but that there are no philosophers; some of Gerson’s more philosophically minded readers may find their prejudices confirmed that in late antiquity there were many who talked about Plato and Aristotle but few who understood what they were trying to do. For it is clear that a general theme of the present volumes is that in late antiquity philosophers were largely concerned to “interpret” Plato and (especially after Porphyry) Aristotle while occasionally seizing the opportunity not merely to rubbish their similarly-engaged predecessors but to add (if shamefacedly) something of their own. Except, that is, for the Christians, whose enterprise was very different and who, quite properly, are more visible in Gerson’s account of late antique thought than in that of Armstrong (though there remain strange omissions in a work on this scale: Methodius, Ambrose, Evagrius).Gerson has tried to contextualize his story by including short (and helpful) historical introductions by Elizabeth DePalma Digeser to the various epochs with which his volumes are concerned, and which can perhaps be divided into four sections: pre-Plotinian Platonism [End Page 136] (plus extras) from Cicero to Numenius; later pagan Platonism, including extensive treatment of the Neoplatonic commentators on Aristotle; Christian thought before Constantine; and later Christian philosophy-cum-theology. Rounding off the volume are introductions to the transition from “ancient” to “medieval” thought in the Latin West (Gersh), in Byzantium—a remarkably honest presentation of a largely stagnant philosophical world by Ierodiakonou and Zografidis—and (in a magisterial improvement on what is to be found in Armstrong) in Islam (Cristina d’Ancona) where (inter multa alia) the roots of the virtually inevitable later destruction of a flourishing philosophical tradition founded by al-Kindi and al-Farabi are identified in the more “orthodox” and theocratic approach—here there are Byzantine parallels—of the followers of al-Ash’ari (885).Gerson’s readers can inspect philosophical wisdom and conceptual muddle among late antique intellectuals—Christians, a few Muslims, pagans—down to Scotus Eriugena and al-Farabi. But some of them may suspect that an opportunity has been lost to reflect on the origins and nature of early Christian thought, and to ask why Christians soon jumped for Platonism rather than Stoicism (Aristotle, let alone Epicurus, was not—yet—considered a serious option)—and that is not intended as criticism of the excellent, if brief, treatment of important Christian thinkers such as Origen. But it was an adventure for Christians to begin to philosophize, and when they embarked on this adventure—here the significance... (shrink)

Dewey presents persuasive arguments against (...) traditional philosophical constructs, suggesting their basis in self-justification. He proposes, instead, an examination of core values in terms of their ultimate effects on the self and others. This experimental philosophy was received with both outrage and acclaim for daring to mingle ethics and science.

[Edited from Conclusion section:] We have looked at various challenging issues to do with getting connectionism to cope with high-level cognitive activities such a reasoning and natural language understanding. The issues are to do with various facets of generalization that are not commonly noted. We have been concerned in particular with the special forms these issues take in the arena of propositional attitude processing. The main problems we have looked at are: (1) The need to construct explicit representations of generalizations, (...) not just generalize correctly to individual cases; (2) The need to be able to match two or more complex short-term information structures, to enable rapid generalization from recent examples rather than from long-term memories; (3) The need to represent and reason with anomalous combinations of concepts; (4) The need to perform embedded reasoning. This presents special problems for systems using non-concatenative representations (as in mainstream connectionist approaches). We also touched on vague quantification in attitude report complements. Neither this topic nor that of analogies between short-term structures (point 2) has been adequately addressed in the symbolic framework, let alone in connectionism. -/- The opportunities and problems covered are put forward as things worth being optimistic about or pessimistic about, respectively. They are not put forward as decisive arguments for or against connectionism. The hope is that this chapter contributes to a greater understanding of the connectionist/symbolist gap by presenting some unusual issues and by throwing new light on some well known ones. (shrink)

Matthew Kramer has recently defended a novel justification for the death penalty, something he calls the purgative rationale. According to this rationale, the death penalty can be justifiably implemented if it is necessary in order to purge defilingly evil offenders from a moral community. Kramer claims that this rationale overcomes the problems associated with traditional rationales for the death penalty. Although Kramer is to be commended for carving out a novel niche in a well-worn dialectical space, I argue that his (...) rationale falls somewhat short of the mark. By his own lights, a successful justification of the death penalty must show that death is the minimally invasive, most humane means to some legitimate moral end. But even if we grant that his rationale picks out a legitimate moral end, there are at least three alternatives to death, either ignored or not fully considered by Kramer, which would seem to satisfy that end in a less invasive, more humane manner.

Kittler’s biographical and intellectual formation, this interview introduces the reader to Kittler’s theoretical efforts to develop our understanding of contemporary culture and society. However, the focus of the interview is on the core concepts of ‘discourse networks’, ‘the military-industrial complex’, and ‘technology’, arguably the three central themes of Kittler’s work to date.

There has recently been a good deal of controversy about Landauer's Principle, which is often stated as follows: The erasure of one bit of information in a computational device is necessarily accompanied by a generation of kT ln 2 heat. This is often generalised to the claim that any logically irreversible operation cannot be implemented in a thermodynamically reversible way. John Norton (2005) and Owen Maroney (2005) both argue that Landauer's Principle has not been shown to hold in general, (...) and Maroney offers a method that he claims instantiates the operation reset in a thermodynamically reversible way. In this paper we defend the qualitative form of Landauer's Principle, and clarify its quantitative consequences (assuming the second law of thermodynamics). We analyse in detail what it means for a physical system to implement a logical transformation L, and we make this precise by defining the notion of an L-machine. Then we show that logical irreversibility of L implies thermodynamic irreversibility of every corresponding L-machine. We do this in two ways. First, by assuming the phenomenological validity of the Kelvin statement of the second law, and second, by using information-theoretic reasoning. We illustrate our results with the example of the logical transformation 'reset', and thereby recover the quantitative form of Landauer's Principle. (shrink)

This book treats ancient logic: the logic that originated in Greece by Aristotle and the Stoics, mainly in the hundred year period beginning about 350 BCE. Ancient logic was never completely ignored by modern logic from its Boolean origin in the middle 1800s: it was prominent in Boole’s writings and it was mentioned by Frege and by Hilbert. Nevertheless, the first century of mathematical logic did not take it seriously enough to study the ancient logic texts. A renaissance in ancient (...) logic studies occurred in the early 1950s with the publication of the landmark Aristotle’s Syllogistic by Jan Łukasiewicz, Oxford UP 1951, 2nd ed. 1957. Despite its title, it treats the logic of the Stoics as well as that of Aristotle. Łukasiewicz was a distinguished mathematical logician. He had created many-valued logic and the parenthesis-free prefix notation known as Polish notation. He co-authored with Alfred Tarski’s an important paper on metatheory of propositional logic and he was one of Tarski’s the three main teachers at the University of Warsaw. Łukasiewicz’s stature was just short of that of the giants: Aristotle, Boole, Frege, Tarski and Gödel. No mathematical logician of his caliber had ever before quoted the actual teachings of ancient logicians. -/- Not only did Łukasiewicz inject fresh hypotheses, new concepts, and imaginative modern perspectives into the field, his enormous prestige and that of the Warsaw School of Logic reflected on the whole field of ancient logic studies. Suddenly, this previously somewhat dormant and obscure field became active and gained in respectability and importance in the eyes of logicians, mathematicians, linguists, analytic philosophers, and historians. Next to Aristotle himself and perhaps the Stoic logician Chrysippus, Łukasiewicz is the most prominent figure in ancient logic studies. A huge literature traces its origins to Łukasiewicz. -/- This Ancient Logic and Its Modern Interpretations, is based on the 1973 Buffalo Symposium on Modernist Interpretations of Ancient Logic, the first conference devoted entirely to critical assessment of the state of ancient logic studies.

Peirce earned his keep making measurements, mainly of gravity but also astronomical, and he made several contributions to the science of measurement. It has been said that his experience measuring had philosophical consequences: his adoption of fallibilism, his argument against necessitarianism, and his conception of inquiry as converging on the truth have all been mentioned. But not much attention has been paid to the curious episode of his making “the study of great men” part of a course in logic: students (...) were asked to rank a long list of men by order of greatness. That was at Johns Hopkins in 1883. I shall argue that that study, together with his reflections on pre-instrumental estimates of stars’ brightness, bears directly on the method of phaneroscopy formulated nearly two decades later. In each case, the problem is to show how objectivity is possible under conditions in which it must seem that objectivity is impossible. (shrink)

This article introduces a new model of the relationship between growth and learning and tests a set of hypotheses related to the development of adult competency using time allocation, anthropometric, and experimental task performance data collected between 1992 and 1997 in a multiethnic community in the Okavango Delta, Botswana. Building on seminal work in life history theory by Hawkes, Blurton Jones and associates, and Kaplan and associates, the punctuated development model presented here incorporates the effects of both growth and learning (...) constraints on age-specific task performance. In addition, the payoff to investment in two forms of embodied capital, growth-based and learning-based, are examined in relation to features of the socioecology, including subsistence economy and family composition.The three main findings are:The development of adult competency in specific tasks entails a steplike relationship between growth- and experience-based forms of embodied capital in the ontogeny of ability acquisition.There is a trade-off between the acquisition of experience-based embodied capital in the form of skills and knowledge and immediate productivity among children. Time allocation to these alternatives is primarily determined by the short- and long-term costs and benefits to parents of investment in children’s embodied capital.The availability of laborers and the overall labor requirements of the household are major determinants of investment in alternate forms of embodied capital and resulting variation in children’s time allocation. The value of children’s labor to their parents is dependent upon the opportunity costs to engaging in other activities not only for the child in question but also for potential substitute laborers.These results have important implications for our understanding of the role of growth and learning in the evolution of the human juvenile period, as well as for our understanding of cross-cultural variation in child growth and development and patterns of work and play.

Higher-order representation (HOR) theories posit that the contents of lower-order brain states enter consciousness when tracked by a higher-order brain state. The nature of higher-order monitoring was examined in light of current scientific knowledge, primarily in experimental perceptual psychology. The most plausible candidate for higher-order state was found to be conceptual short-term memory (CSTM), a buffer memory intimately connected with a semantic engine operating in the medium of the language of thought (LOT). This combination meets many of the requirements (...) of HOR theories, although falling short in some significant respects, most notably the inability of higher- order states to represent more than a small fraction of the information contained in primary states, especially in vision. A possible way round this obstacle is suggested, involving the representation of visual detail by means of ensemble concepts. (shrink)

Who or what is God? How do different religions interpret God's existence? How can we know God? Many people believe in God; not just throughout history but also in the present day.

This Very Short Introduction explores some of the answers provided by philosophers, poets, and theologians, and considers why some people believe in God and others do not. (...)
