Physical exercise is seen as the main ally for health promotion, preventing and protecting the organism from several diseases. According to WHO, there is a tendency of constant growth in the elderly population in the coming years. The regular practice of exercises by the elderly becomes relevant to minimize the deleterious effects of the aging process and to increase the fitness index. Recently, the world population started a confrontation against Corona Virus Disease (COVID-19), which is the most significant public health (...) challenge globally. Although social isolation is a reasonable measure in an attempt to stop contamination by COVID-19, this measure has limited the ability of individuals to exercise outdoors or in gyms and health clubs, which increased the risk of developing chronic illnesses related to a sedentary lifestyle. The critical point is that the recent recommendations on exercise prescription to combat the potentially harmful effects of COVID-19 failure to adequately address resistance exercise interventions as home-based exercise strategy. Thus, in this paper, we discussed the physical exercise as medicine if the training status is enough to protect the elderly against COVID-19 infection, about the role of physical activity on immunosuppression. Possible risks for COVID-19 infection, and the old training methods, such as no-load resistance training as possible resistance exercise strategies and high-intensity interval training, as new proposals of home-based exercise interventions, could perform during the current COVID-19 pandemic.

Physicians place significant weight on the distinction between acts and omissions. Most believe that autonomous refusals for procedures, such as blood transfusions and resuscitation, ought to be respected, but they feel no similar obligation to accede to requests for treatment that will, in the physician’s opinion, harm the patient (e.g., assisted death). Thus, there is an asymmetry. In this paper, we challenge the strength of this distinction by arguing that the ordering of values should be the same in both cases. (...) The reason for respecting refusals is that, in such cases, autonomy outweighs well-being. We argue that the same should be true in request cases, which means that requests should not be denied only due to the treatment being too harmful in the physician’s opinion. Our strategy is to consider and reject a number of arguments for the asymmetrical view, including an appeal to the doing–allowing distinction and positive and negative rights. The duty to respect refusals is still greater than the duty to grant requests on our view, but, by arguing that the ordering of values is the same in both cases, we show that there is less of a distinction in healthcare between requests and refusals than many currently believe.

Central aspects of Hume’s proposed “system of the sciences” as described in the Treatise are modeled on Newton’s Principia. But, as recent scholarship has suggested, Hume’s Treatise also bears a deeply subversive message with respect to Newtonian science. This chapter offers a revised overview of what Hume takes from Newton and what he rejects: The first part of the chapter argues that in the Treatise Hume adopts a version of Newton’s “analytic and synthetic method” for philosophy, thereby placing a distinctively (...) Newtonian form of explanatory reduction at the center of his own philosophical method. The second part of the chapter, on the other hand, shows that many of the most important aspects of Hume’s argument in Book 1 of the Treatise can be understood as critical of core conceptual and ontological commitments of Newton’s mechanics as developed in the Principia.

There is much to admire in this book. It is written in a pleasingly straightforward style, and offers insight on a wide range of important issues.

Climate change and justice are so closely associated that many people take it for granted that a global climate treaty should--indeed, must--directly address both issues together. But, in fact, this would be a serious mistake, one that, by dooming effective international limits on greenhouse gases, would actually make the world's poor and developing nations far worse off. This is the provocative and original argument of Climate Change Justice. Eric Posner and David Weisbach strongly favor both a climate change agreement (...) and efforts to improve economic justice. But they make a powerful case that the best--and possibly only--way to get an effective climate treaty is to exclude measures designed to redistribute wealth or address historical wrongs against underdeveloped countries. In clear language, Climate Change Justice proposes four basic principles for designing the only kind of climate treaty that will work--a forward-looking agreement that requires every country to make greenhouse--gas reductions but still makes every country better off in its own view. This kind of treaty has the best chance of actually controlling climate change and improving the welfare of people around the world. (shrink)

Foundational theories of mental content seek to identify the conditions under which a mental representation expresses, in the mind of a particular thinker, a particular content. Normativists endorse the following general sort of foundational theory of mental content: A mental representation r expresses concept C for agent S just in case S ought to use r in conformity with some particular pattern of use associated with C. In response to Normativist theories of content, Kathrin Glüer-Pagin and Åsa Wikforss propose a (...) dilemma, alleging that Normativism either entails a vicious regress or falls prey to a charge of idleness. In this paper, I respond to this argument. I argue that Normativism can avoid the commitments that generate the regress and does not propose the sort of explanation required to charge that its explanation has been shown to be problematically idle. The regress-generating commitment to be avoided is, roughly, that tokened, contentful mental states are the product of rule-following. The explanatory task Normativists should disavow is that of explaining how it is that beliefs and other contentful mental states are produced. I argue that Normativism, properly understood as a theory of content, does not provide this kind of psychological explanation, and therefore does not entail that such explanations are to be given in terms of rule-following. If this is correct, Normativism is not the proper target of the dilemma offered by Glüer-Pagin and Wikforss. Understanding why one might construe Normativism in the way Glüer-Pagin and Wikforss must, and how, properly understood, it avoids their dilemma, can help us to appreciate the attractiveness of a genuinely normative theory of content and the importance of paying careful attention to the sort of normativity involved in norm-based theories of content.

Over the last several years, there has been an explosion of interest and attention devoted to the problem of Uncertainty Quantification (UQ) in climate science—that is, to giving quantitative estimates of the degree of uncertainty associated with the predictions of global and regional climate models. The technical challenges associated with this project are formidable, and so the statistical community has understandably devoted itself primarily to overcoming them. But even as these technical challenges are being met, a number of persistent conceptual (...) difficulties remain. So why is UQ so important in climate science? UQ, I would like to argue, is first and foremost a tool for communicating knowledge from experts to policy makers in a way that is meant to be free from the influence of social and ethical values. But the standard ways of using probabilities to separate ethical and social values from scientific practice cannot be applied in a great deal of climate modeling, because the roles of values in creating the models cannot be discerned after the fact—the models are too complex and the result of too much distributed epistemic labor. I argue, therefore, that typical approaches for handling ethical/social values in science do not work well here. (shrink)

The ArgumentIn its reconstruction of scientific practice, philosophy of science has traditionally placed scientific theories in a central role, and has reduced the problem of mediating between theories and the world to formal considerations. Many applications of scientific theories, however, involve complex mathematical models whose constitutive equations are analytically unsolvable. The study of these applications often consists in developing representations of the underlying physics on a computer, and using the techniques of computer simulation in order to learn about the behavior (...) of these systems. In many instances, these computer simulations are not simple number-crunching techniques. They involve a complex chain of inferences that serve to transform theoretical structures into specific concrete knowledge of physical systems. In this paper I argue that this process of transformation has its own epistemology. I also argue that this kind of epistemology is unfamiliar to most philosophy of science, which has traditionally concerned itself with the justification of theories, not with their application. Finally, I urge that the nature of this epistemology suggests that the end results of some simulations do not bear a simple, straightforward relation to the theories from which they stem. (shrink)

Individuals who become ill as a result of personal lifestyle choices often shift the monetary costs of their healthcare needs to the taxpaying public or to fellow members of a private insurance pool. Some argue that policies permitting such cost shifting are unfair. Arguments for this view may seem to draw support from luck egalitarian accounts of distributive justice. This essay argues that the luck egalitarian framework provides no such support. To allocate healthcare costs on the basis of personal responsibility (...) would arbitrarily and publicly burden socially detectable risk-takers while undetectable risk-takers continue to get a free ride. That problem is unavoidable even on the assumption that distributive institutions outside the healthcare sector are fully just. In actual, farfrom-just societies, imposing personal liability for the costs of voluntary risk taking would be wrong for an additional reason. Doing so would tend to magnify existing distributive injustices. These conclusions draw attention to two common ‘moral fallacies of the second best’ that can arise when applying ideal normative theory to matters of institutional design and in real-world policy contexts.

International borders concentrate opportunities in some societies while limiting them in others. Borders also prevent those in the less favored societies from gaining access to opportunities available in the more favored ones. Both distributive effects of borders are treated here within a comprehensive framework. I argue that each state should have broad discretion under international law to grant or deny entry to immigration seekers; but more favored countries that find themselves under immigration pressure should be legally obligated to fund development (...) assistance for countries that generate immigration pressure. Funding should be subject to conditions of fair and effective use in recipient countries, and should aim at a near-term target of immigration-pressure equilibrium. Equilibrium obtains between two countries when, given appropriate background circumstances, the same proportion of individuals in each manifests a preference to migrate to the other. If meeting the equilibrium target in the short term would be to the long-term disadvantage of the worst-off countries, then a Pareto-superior alternative target supersedes. It mandates development assistance at the level that yields the most favorable human development projections for the worstoff countries. An implementable set of institutions is described that can achieve the equilibrium goal in the long term without unduly sacrificing other important ends, including economic growth, political stability, cultural integrity, the political autonomy of distinct societies, and their proper accountability for policy choices. Key Words: global justice • immigration • borders • development • distributive justice • development assistance • equality • international law • cosmopolitanism. (shrink)

I argue for two major claims in this paper. First, I argue that the linguistic evidence best supports a certain form of contextualism about predicates of personal taste (PPTs) like ?fun? and ?tasty?. In particular, I argue that these adjectives are both individual-level predicates (ILPs) and anaphoric implicit argument taking predicates (IATPs). As ILPs, these naturally form generics. As anaphoric IATPs, PPTs show the same dependencies on context and distributional behavior as more familiar anaphoric IATPs, for example, ?local? and ?apply?. (...) Moreover, they are subject to important binding-related phenomena, for example, various kinds of anaphora, binding arguments, and strict-sloppy ambiguities. The latter are particularly problematic for relativism, contextualism's major competitor. I argue that relativism cannot account for these binding facts in a non-ad hoc manner. Second, I argue that disagreement is a predictable feature of dialogues involving PPTs in conjunction with the contextualist semantics defended. Appealing to ?off the shelf? analyses of genericity, I show how disagreement arises in just the cases we would expect, licensing just the kinds of responses we would expect. They also suggest promising explanations, unavailable to relativists, of various otherwise puzzling features of disagreements involving PPTs. (shrink)

Augustine—for all of his influence on Western culture and politics—was hardly a liberal. Drawing from theology, feminist theory, and political philosophy, Eric Gregory offers here a liberal ethics of citizenship, one less susceptible to anti-liberal critics because it is informed by the Augustinian tradition. The result is a book that expands Augustinian imaginations for liberalism and liberal imaginations for Augustinianism. Gregory examines a broad range of Augustine’s texts and their reception in different disciplines and identifies two classical themes which (...) have analogues in secular political theory: love—and related notions of care, solidarity, and sympathy—and sin—as well as related notions of cruelty, evil, and narrow self-interest. From an Augustinian point of view, Gregory argues, love and sin constrain each other in ways that yield a distinctive vision of the limits and possibilities of politics. In providing a constructive argument for Christian participation in liberal democratic societies, Gregory advances efforts to revive a political theology in which love’s relation to justice is prominent. _Politics and the Order of Love _will provoke new conversations for those interested in Christian ethics, moral psychology, and the role of religion in a liberal society.

In this paper we discuss the two-system framework, examine its strengths, point out a fundamental weakness concerning the unity of conscious experience, and then propose a new hypothesis that avoids that weakness and other related concerns. According to our strong emergence hypothesis, what emerges are not merely mental properties in specialized, distributed neural areas, but also a new, irreducibly singular entity that functions in a recurrent manner to integrate its mental properties and to rewire its brain. We argue that the (...) former function is suggested, in part, by the effects of anesthetics on sensory integration, and that the latter function is suggested by evidence garnered from the neuroscience of mindfulness, constraint-induced movement therapy for stroke, and neuroimaging data surrounding mental illness. We then discuss how our strong emergence hypothesis relates to the description and treatment of neuropsychiatric disorders. Finally, potential objections are addressed. (shrink)

Anecdotal evidence from many hunter-gatherer societies suggests that successful hunters experience higher prestige and greater reproductive success. Detailed quantitative data on these patterns are now available for five widely dispersed cases (Ache, Hadza, !Kung, Lamalera, and Meriam) and indicate that better hunters exhibit higher age-corrected reproductive success than other men in their social group. Leading explanations to account for this pattern are: (1) direct provisioning of hunters’ wives and offspring, (2) dyadic reciprocity, (3) indirect reciprocity, (4) costly signaling, and (5) (...) phenotypic correlation. I examine the qualitative and quantitative evidence bearing on these explanations and conclude that although none can be definitively rejected, extensive and apparently unconditional sharing of large game somewhat weakens the first three explanations. The costly signaling explanation has support in some cases, although the exact nature of the benefits gained from mating or allying with or deferring to better hunters needs further study. (shrink)

An integrated representation of large‐scale space, or cognitive map, colled PLAN, is presented that attempts to address a broader spectrum of issues than has been previously attempted in a single model. Rather than examining way‐finding as a process separate from the rest of cognition, one or the fundamental goals of this work is to examine how the wayfinding process is integrated into general cognition. One result of this approach is that the model is “heads‐up,” or scene‐based, because it takes advantage (...) of the properties of the human visual system and, particularly, the visual system's split into two pathways. The emphasis on the human location or “where” system is new to cognitive mapping and is port of an attempt to synthesize prototype theory, associative networks and location together in a connectionist system. Not all of PLAN is new, however. Many of its parts have analogues in one or another preexisting theory. What makes PLAN unique is integrating the various components into a coherent whole, and the capacity of this resulting system to speak to a wide range of constraints. Our approach emphasizes adaptiveness; thus, our focus on such issues as ease of use and efficiency of learning. The result is a model that has a stronger relationship both to the environment, and to the ways that humans interact with it, compared with previous models. The resulting model is examined in some detail and compared to other systems. (shrink)

The 1964 theorem of John Bell shows that no model that reproduces the predictions of quantum mechanics can simultaneously satisfy the assumptions of locality and determinism. On the other hand, the assumptions of signal locality plus predictability are also sufficient to derive Bell inequalities. This simple theorem, previously noted but published only relatively recently by Masanes, Acin and Gisin, has fundamental implications not entirely appreciated. Firstly, nothing can be concluded about the ontological assumptions of locality or determinism independently of each (...) other—it is possible to reproduce quantum mechanics with deterministic models that violate locality as well as indeterministic models that satisfy locality. On the other hand, the operational assumption of signal locality is an empirically testable (and well-tested) consequence of relativity. Thus Bell inequality violations imply that we can trust that some events are fundamentally unpredictable, even if we cannot trust that they are indeterministic. This result grounds the quantum-mechanical prohibition of arbitrarily accurate predictions on the assumption of no superluminal signalling, regardless of any postulates of quantum mechanics. It also sheds a new light on an early stage of the historical debate between Einstein and Bohr. (shrink)

To date, emotion research has primarily focused on the experience and display of the emoter. However, of equal, if not more, importance is how such displays impact and guide the behavior of an observer. We incorporate a functionalist framework of emotion to examine the development of differential responding to discrete emotion, theorize on what may facilitate its development, and hypothesize the functions that may underlie such behavioral responses. Although our review is focused primarily on development, the theoretical and methodological ideas (...) laid out are relevant for researchers of emotion at all ages. (shrink)

I apply some of the lessons from quantum theory, in particular from Bell’s theorem, to a debate on the foundations of decision theory and causation. By tracing a formal analogy between the basic assumptions of causal decision theory (CDT)—which was developed partly in response to Newcomb’s problem— and those of a local hidden variable theory in the context of quantum mechanics, I show that an agent who acts according to CDT and gives any nonzero credence to some possible causal interpretations (...) underlying quantum phenomena should bet against quantum mechanics in some feasible game scenarios involving entangled systems, no matter what evidence they acquire. As a consequence, either the most accepted version of decision theory is wrong, or it provides a practical distinction, in terms of the prescribed behaviour of rational agents, between some metaphysical hypotheses regarding the causal structure underlying quantum mechanics.

In “Generalizing Generalizability in Information Systems Research,” Lee and Baskerville try to clarify generalization and classify it into four types. Unfortunately, their account is problematic. We propose repairs. Central among these is our balance-of-evidence argument that we should adopt the view that Hume’s problem of induction has a solution, even if we do not know what it is. We build upon this by proposing an alternative classification of induction. There are five types of generalization: theoretical, within-population, cross-population, contextual, and temporal, (...) with theoretical generalization being across the empirical and theoretical levels and the rest within the empirical level. Our classification also includes two kinds of inductive reasoning that do not belong to the domain of generalization. We then discuss the implications of our classification for information systems research. (shrink)

At the dawn of the new century, Robert Plomin was gloomy. As he recounts in Blueprint: How DNA Makes Us Who We Are, attempts to find the DNA responsible for the heritability of behavior failed. Month after month, journals would report new findings of specific genes for behavioral phenotypes, but they never replicated. One amazing genomic methodology after another was developed in biological genetics and applied to medicine, where it succeeded, and then to human behavior, where it failed. This was (...) the moment of Plomin's despair. He had, with great intellectual courage, staked his reputation on the existence of actionable scientific knowledge of the DNA‐based genesis of twin‐based heritability. But Blueprint is hardly the product of a gloomy author. Quite the opposite: it is a declaration of victory of nature over nurture, a celebration of the vindication of Plomin as a scientist and of behavior genetics as a field of study. What happened between 2000 and 2019 to brighten Plomin's outlook so radically? Were the genes for schizophrenia and intelligence finally discovered? Are we at last on our way to understanding why, at a biological level, all differences in human behavior are substantially heritable? Alas, no. What happened is that Robert Plomin gave up on the search for individual genes that explain heritability and decided to be satisfied with much less. (shrink)

The Prudence of Love focuses upon the intersection of philosophical, theological, and psychological issues related to love. Eric Silverman defends an account of love derived from the views of Thomas Aquinas and argues that love provides numerous psychological and relational benefits that increase the lover's happiness. Furthermore, he argues that love is beneficial according to all major contemporary accounts of happiness.

Essays by some of the world's leading educators provide a revolutionary portrait of new ideas and developments in education that can influence the possibility of social and political change. The authors take into account such diverse terrain as feminism, ecology, media, and individual liberty in their pursuit of new ideas that can inform the fundamental practice of education and promote a more humane civil society. The book consolidates recent thinking just as it reflects on emerging new lines of critical theory.

The relationship between game play and naturalistic cooperation, generosity, or market involvement is ambiguous at best, making it difficult to link game results to preferences and beliefs guiding decision-making in daily life. Discounting reputation-based explanations because the games are anonymous, while arguing that game play is guided by motivational structures or framing effects reflecting daily life, is inconsistent.

Eric Osborn's book presents a major study of Irenaeus, bishop of Lyons, who attacked Gnostic theosophy with positive ideas as well as negative critiques. Irenaeus's combination of argument and imagery, logic and aesthetic, was directed to the bible. Dominated by a Socratic love of truth and a classical love of beauty, he was a founder of Western humanism. Erasmus, who edited the first printed edition of Irenaeus, praised him for his freshness and vigour. He is today valued for his (...) splendid aphorisms, his optimism, love of the created world, evolutionary view of history, theology of beauty and humour. Why have two millennia of European culture been so creative? Irenaeus points to Greek ways of thinking and the Christian Bible. Irenaeus's thought is complex, yet rewarding to the critical reader, and this full study of it will be of interest to theologians, historians of ideas, classicists, scientists and students. (shrink)

This paper addresses methodological and metatheoretical aspects of the ongoing debate over the adaptive significance of Tibetan polyandry. Methodological contributions include a means of estimating relatedness of fraternal co-husbands given multigenerational polyandry, and use of Hamilton’s rule and a member-joiner model to specify how inclusive fitness gains of co-husbands may vary according to seniority, opportunity costs, and group size. These methods are applied to various data sets, particularly that of Crook and Crook (1988). The metatheoretical discussion pivots on the critique (...) by evolutionary psychologists of adaptationist accounts of polyandry. Contrary to this critique, I argue that valid adaptationist explanations of such practices do not necessitate cognitive mechanisms evolved specifically to produce polyandry, nor that there must have been exact equivalents of Tibetan agricultural estates and social institutions in human evolutionary history. Specific issues raised when one posits either kin selection or cultural evolution to explain the adaptive features of Tibetan polyandry are also discussed. (shrink)

Charles S. Peirce’s theory of proper names bears helpful insights for how we might think about his understanding of persons. Persons, on his view, are continuities, not static objects. I argue that Peirce’s notion of the legisign, particularly proper names, sheds light on the habitual and conventional elements of what it means to be a person. In this paper, I begin with an account of what philosophers of language have said about proper names in order to distinguish Peirce’s theory of (...) proper names from them. Then, I present Peirce’s semiotic theory of proper names, followed by some ways in which his theory can be applied to practical concerns, such as first impressions, name changing, identity, and temporary insanity.

Children and individuals with developmental disabilities compared to typical participants are disadvantaged not only by virtue of being vulnerable to risks inherent in research participation but also by the higher likelihood of exclusion from research altogether. Current regulatory and ethical guidelines although necessary for their protection do not sufficiently ensure fair distributive justice. Yet, in view of disproportionately higher burdens of co-occurring physical and mental disorders in individuals with DD, they are better positioned to benefit from research by equitable participation. (...) Greater elucidation of this ethical dilemma is called for by researchers, institutional review boards, and funding agencies to urgently redress the imbalance. This article discusses many of the regulatory principles to ensure better research participation of children and individuals with DD: human rights, validity, distributive justice, beneficence/nonmaleficence, and autonomy.

While theorizing in distinctly different times, distinctly different cultures, and under distinctly different circumstances, notable philosophical similarities can be drawn between John Dewey and Paulo Freire. This article focuses on two major themes evident in a sample of each philosopher's major works, democracy and experience, and draws theoretical comparisons between the way each philosopher approaches these concepts in terms of definition and application to educational and social practice. The author suggests that, despite some paradigmatic differences, the fundamental definitions and uses (...) of these concepts expressed by both philosophers are largely comparable and complementary.

Recent experimental evidence indicates that intuitions about inherence and system justification are distinct psychological processes, and that the inherence heuristic supplies important explanatory frameworks that are accepted or rejected based on their consistency with one's motivation to justify the system.

Abstract: In this essay a set of principles is defended that yields a determinate allocation of sovereign competences across a global system of territorially nested jurisdictions. All local sovereign competences are constrained by a universal, justiciable human rights regime that also incorporates a conception of cross-border distributive justice and regulates the competence to control immigration for a given territory. Subject to human rights constraints, sovereign competences are allocated according to a conception of global democracy. The proposed allocation scheme can accommodate (...) substantial local autonomy while at the same time ensuring that everyone has a voice in the political decisions that affect his or her interests. The relevant class of affected interests is fully specified. Relevant affects are of two kinds: those that impose norms of governance on individuals, and those that impose external costs on them. The favored sense of "an external cost" is developed and defended. (shrink)

We pose a foundational problem for those who claim that subjects are ontologically irreducible, but causally reducible (weak emergence). This problem is neuroscience’s notorious binding problem, which concerns how distributed neural areas produce unified mental objects (such as perceptions) and the unified subject that experiences them. Synchrony, synapses and other mechanisms cannot explain this. We argue that this problem seriously threatens popular claims that mental causality is reducible to neural causality. Weak emergence additionally raises evolutionary worries about how we’ve survived (...) the perils of nature. Our emergent subject hypothesis (ESH) avoids these shortcomings. Here, a singular, unified subject acts back on the neurons it emerges from and binds sensory features into unified mental objects. Serving as the mind’s controlling center, this subject is ontologically and causally irreducible (strong emergence). ESH draws on recent experimental evidence, including the motivation of a possible correlate (or “seat”) of the subject, which enhances its testability. (shrink)

Kai Wehmeier’s Wittgensteinian Predicate Logic is a formulation of first-order logic under the exclusive interpretation of the quantifiers. W-logic has a distinguished relation constant for co-reference but no sign for objectual identity. Wehmeier denies that objectual identity exists on the grounds that it cannot be a genuine binary relation. Fortunately W-logic is equi-expressive with standard first-order logic with identity and it appears that objectual identity is dispensable across the broader logical enterprise. This paper challenges the latter claim as objectual identity (...) seems to be needed in the exclusive interpretation of quantified modal logic, specifically, for implementing certain kinds of de re quantification.

Novels in general use three different modes of reporting: narration, dialogue and description. Understanding that even with a given mode, such as the description of a stone, the relation between the diachronic flow of language and the synchronic focus of attention can be manipulated, we can still note that in general narration reports occurrences in a reading time considerably less than actual time. , dialogue reports occurrence in a reading time roughly congruent with actual time , and description reports occurrences (...) in a reading time considerably greater than actual time . Thus, in the interweaving of narration, dialogue and description a narrative not only defamiliarizes what it reports but guides the reader's consciousness through rhythms of correspondence between reading time and actual time. As long as we do not stay entirely in one mode—and we never do—these rhythms adjust the movement of our consciousness so that unconsciously at least we more or less approach synchronicity, depending on the particular techniques—but we never achieve it. Spatial form may be thought of as a tendency, but in ordinary language it is never achieved. Eric S. Rabkin is professor of English at the University of Michigan at Ann Arbor. The author of Narrative Suspense, The Fantastic in Literature, and many articles on science fiction, he is also the coauthor of Form in Fiction and Science Fiction: History, Science, Vision.
