Phase 1 healthy volunteer clinical trials—which financially compensate subjects in tests of drug toxicity levels and side effects—appear to place pressure on each joint of the moral framework justifying research. In this article, we review concerns about phase 1 trials as they have been framed in the bioethics literature, including undue inducement and coercion, unjust exploitation, and worries about compromised data validity. We then revisit these concerns in light of the lived experiences of serial participants who are income-dependent on (...) phase 1 trials. We show how participant experiences shift attention from discrete exchanges, behaviors, and events in the research enterprise to the ongoing and dynamic patterns of serial participation in which individual decision-making is embedded in collective social and economic conditions and shaped by institutional policies. We argue in particular for the ethical significance of structurally diminished voluntariness, routine powerlessness in setting the terms of exchange, and incentive structures that may promote pharmaceutical interests but encourage phase 1 healthy volunteers to skirt important rules.

All other things being equal the parser favors attaching an ambiguous modifier to the most recent possible site. A plausible explanation is that locality preferences such as this arise in the service of minimizing memory costs—more distant sentential material is more difficult to reactivate than more recent material. Note that processing any sentence requires linking each new lexical item with material in the current parse. This often involves the construction of long‐distance dependencies. Under a resource‐limited view of language processing, lengthy (...) integrations should induce difficulty even in unambiguous sentences. To date there has been little direct quantitative evidence in support of this perspective. This article presents 2 self‐paced reading studies, which explore the hypothesis that dependency distance is a fundamental determinant of reading complexity in unambiguous constructions in English. The evidence suggests that the difficulty associated with integrating a new input item is heavily determined by the amount of lexical material intervening between the input item and the site of its target dependents. The patterns observed here are not straightforwardly accounted for within purely experience‐based models of complexity. Instead, this work supports the role of a memory bottleneck in language comprehension. This constraint arises because hierarchical linguistic relations must be recovered from a linear input stream.

Studies of implicit learning have shown that individuals exposed to a rule-governed environment often learn to exploit 'rules' which describe the structural relationship between environmental events. While some authors have interpreted such demonstrations as evidence for functionally separate implicit learning systems, others have argued that the observed changes in performance result from explicit knowledge which has been inadequately assessed. In this paper we illustrate this issue by considering one commonly used implicit learning task, the Serial reaction time task, and (...) outline what we see as an important problem associated with each of the commonly used methods used to assess explicit knowledge. This is that each measure requires a form of response which is dependent on the subjects having some knowledge of the serial-order of the sequence. We argue that such methods, or more specifically their analyses, seriously underestimate other sources of knowledge, which may be available to subjects during their performance of the SRT task. In support of this argument we demonstrate that subjects' serial-order knowledge can, in principle, be independent of subjects' knowledge of the statistical structure of the sequence, and we propose an alternative method for analysing performance on the Generate task which avoids this problem.

Research on cognitive control has sparked increasing interest in recent years, as it is an important prerequisite for goal oriented human behavior. The paced auditory serial addition task has been used to test and train cognitive control functions. This adaptive, challenging task includes continuous performance feedback. Therefore, additional cognitive control capacities are required to process this information along with the already high task-load. The underlying neural mechanisms, however, are still unclear. To explore the neural signatures of the PASAT and (...) particularly the processing of distractive feedback information, feedback locked event-related potentials were derived from 24 healthy participants during an adaptive 2-back version of the PASAT. Larger neural activation after negative feedback was found for feedback related negativity, P300, and late positive potential. In early stages of feedback processing, a larger difference between positive and negative feedback responses was associated with poorer overall performance. This association was inverted in later stages. Together, our findings indicate stage-dependent associations between neural activation after negative information and cognitive functioning. Conceivably, increased early responses to negative feedback signify distraction, whereas higher activity at later stages reflects cognitive control processes to preserve ongoing performance.

Fractal structure is a ubiquitous property found in nature and biology, and has been observed in processes at different levels of organization, including rhythmic behavior and musical structure. A temporal process is characterized as fractal when serial long-term correlations and statistical self-similarity (scaling) are present. Previous studies of sensorimotor synchronization using isochronous (non-fractal) stimuli show that participants' errors exhibit persistent structure (positive long-term correlations), while their inter-tap intervals (ITIs) exhibit anti-persistent structure (negative long-term correlations). Auditory-motor synchronization has not been (...) investigated with anti-persistent stimuli. In the current study, we systematically investigated whether the fractal structure of auditory rhythms was reflected in the responses of participants who were asked to coordinate their taps with each event. We asked musicians and non-musicians to tap with 12 different rhythms that ranged from anti-persistent to persistent. The scaling exponents of the ITIs were strongly correlated with the scaling exponents of the stimuli, showing that the long-term structure of the participants' taps scaled with the long-term structure of the stimuli. Surprisingly, the performance of the musicians was not significantly better than that of the non-musicians. Our results imply that humans are able to readily adapt (rather than simply react) to the overall statistical structure of temporally fluctuating stimuli, regardless of musical skill. (shrink)

Limited distribution phenomena related to negation and negative polarity are usually thought of in terms of affectivity where affective is understood as negative or downward entailing. In this paper I propose an analysis of affective contexts as nonveridical and treat negative polarity as a manifestation of the more general phenomenon of sensitivity to (non)veridicality (which is, I argue, what affective dependencies boil down to). Empirical support for this analysis will be provided by a detailed examination of affective dependencies in Greek, (...) but the distribution of any will also be shown to follow from (non)veridicality.

This unique volume explores what ethics has to offer the practicing physician, nurse, and allied health care worker. The authors introduce the basic vocabulary of ethics and present and discuss the most commonly used ethical theories, using case studies to illustrate how ethics work within the context of health care. Newcomers to the field will learn what ethics is all about and how it relates to the pragmatic concerns of the health care professional. Those who already have a working knowledge (...) of the field will find a new approach to ethical theory--personalism--which the authors believe can make the practical use of ethics more effective and reliable.

If all dependent expressions were adjacent some variety of immediate constituent analysis would suffice for grammar, but syntactic and semantic mismatches are characteristic of natural language; indeed this is a, or the, central problem in grammar. Logical categorial grammar reduces grammar to logic: an expression is well-formed if and only if an associated sequent is a theorem of a categorial logic. The paradigmatic categorial logic is the Lambek calculus, but being a logic of concatenation the Lambek calculus can only capture (...) discontinuous dependencies when they are peripheral. In this paper we present the displacement calculus, which is a logic of intercalation as well as concatenation and which subsumes the Lambek calculus. On the empirical side, we apply the new calculus to discontinuous idioms, quantification, VP ellipsis, medial extraction, pied-piping, appositive relativisation, parentheticals, gapping, comparative subdeletion, cross-serial dependencies, reflexivization, anaphora, dative alternation, and particle shift. On the technical side, we prove that the calculus enjoys Cut-elimination. (shrink)

We are currently witnessing a fundamental structural transformation of the scientific public sphere, characterized by processes of specialization, metrification, internationalization, platformization and visibilization. In contrast to explanations of this structural transformation that invoke a technological determinism, we demonstrate its historical contingency by drawing on analytic concepts from organization theory and the case of the Open Access transformation in Germany. The digitization of academic journals has not broadened access to scientific output but narrowed it down even further in the course of (...) the ‘serials crisis’. For a long time, research institutions were not able to convince large academic publishers to adopt less restrictive forms of access to academic journals. It was only through the emergence of new and in part illegal actors (shadow libraries and preprint servers) that the existing path could be broken, and an Open Access path constituted. Following this analysis, we discuss consequences of the Open Access transformation for the public spheres of science and democracy. We conclude that Open Access publishing can only help to transform both communicative spaces towards the normative ideal of a public sphere when complemented by systematic support for non-profit publication infrastructures.

Inaccurate body size judgements are associated with body image disturbances, a clinical feature of many eating disorders. Accordingly, body related stimuli have become increasingly important in the study of estimation inaccuracies and body image disturbances. Technological advancements in the last decade have led to an increased use of computer generated (CG) body stimuli in body image research. However, recent face perception research has suggested that CG face stimuli are not recognised as readily and may not fully tap facial processing mechanisms. (...) The current study assessed the effectiveness of using CG stimuli in an established body size estimation task (the ‘bodyline’ task). Specifically, we examined whether employing CG body stimuli alters body size judgments and associated estimation biases. One hundred and six 17- to 25-year-old females completed the CG bodyline task, which involved estimating the size of full-length CG body stimuli along a visual analogue scale. Our results show that perception of body size for CG stimuli was non-linear. Participants struggled to discriminate between extreme bodies sizes and overestimated the size change between near to average bodies. Furthermore, one of our measured size estimation biases was larger for CG stimuli. Our collective findings suggest using caution when employing CG stimuli in experimental research on body perception.

A serial reaction time experiment tested the hypothesis that there are two independent forms of implicit learning: learning that is linked to making judgments about stimuli, and learning that is linked to motor processing. Participants performed 2, 6, or 12 blocks of single task SRT, dual task SRT, or observation with one of five sequences; each sequence had the same underlying structure. Participants then performed two implicit tests, SRT and pattern judgment, as well as a generation test and an (...) explicit knowledge test. There was a double dissociation of the effect of sequence surface structure on SRT and pattern judgment. SRT and pattern judgment competence developed independently of each other across length of acquisition task. Performance on both implicit tasks did not depend on explicit knowledge. These results indicate that the SRT and pattern judgment measures tap independent forms of implicit learning, which is consistent with the modular nature of memory and cognition. (shrink)

Prediction‐based processes appear to play an important role in language. Few studies, however, have sought to test the relationship within individuals between prediction learning and natural language processing. This paper builds upon existing statistical learning work using a novel paradigm for studying the on‐line learning of predictive dependencies. Within this paradigm, a new “prediction task” is introduced that provides a sensitive index of individual differences for developing probabilistic sequential expectations. Across three interrelated experiments, the prediction task and results thereof are (...) used to bridge knowledge of the empirical relation between statistical learning and language within the context of nonadjacency processing. We first chart the trajectory for learning nonadjacencies, documenting individual differences in prediction learning. Subsequent simple recurrent network simulations then closely capture human performance patterns in the new paradigm. Finally, individual differences in prediction performances are shown to strongly correlate with participants’ sentence processing of complex, long‐distance dependencies in natural language. (shrink)

Nissen and Bullemer's serial reaction time task has proven to be a useful model task for exploring implicit sequence learning. Neuropsychological research indicates that SRT learning may depend on the integrity of the basal ganglia, but not on medial temporal and diencephalic structures that are crucial for explicit learning. Recent neuroimaging research demonstrates that motor cortical areas , prefrontal, and parietal cortex also may be involved. This paper reviews this neuropsychological and neuroimaging research, but finds it lacking specific links (...) between structure and function. In order to promote better functional hypotheses, the second part of the paper examines the function of these brain areas from a broader perspective. Neuroimaging and neuropsychological research with human subjects, as well as neurophysiological and lesion research with animals, suggests a number component operations that these brain mechanisms may contribute to learning in the SRT task.

Many people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form. Others have argued that a biological specialization for grammar is incompatible with every tenet of Darwinian theory – that it shows no genetic variation, could not exist in any intermediate forms, confers (...) no selective advantage, and would require more evolutionary time and genomic space than is available. We examine these arguments and show that they depend on inaccurate assumptions about biology or language or both. Evolutionary theory offers clear criteria for when a trait should be attributed to natural selection: complex design for some function, and the absence of alternative processes capable of explaining such complexity. Human language meets these criteria: Grammar is a complex mechanism tailored to the transmission of propositional structures through a serial interface. Autonomous and arbitrary grammatical phenomena have been offered as counterexamples to the position that language is an adaptation, but this reasoning is unsound: Communication protocols depend on arbitrary conventions that are adaptive as long as they are shared. Consequently, language acquisition in the child should systematically differ from language evolution in the species, and attempts to analogize them are misleading. Reviewing other arguments and data, we conclude that there is every reason to believe that a specialization for grammar evolved by a conventional neo-Darwinian process. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 12.3 (2005) 257-259 [Access article in PDF] Atrocity, Banality, Self-Deception Adam Morton Keywords evil, self-deception, banality, atrocity, motivation When talking about evil we must make a fundamental choice about how we are to use the term. We may use it as half of the contrast "good versus evil," in which case it covers everything that is not good. That includes moral incompetence, lack of imagination, (...) willingness to follow orders, overreactions, and a host of other reasons why people who do not have personalities that we would call evil do things that are wrong, often very wrong. Call this the weak reading of evil: evil as wrongdoing. Or we may use it with the meaning suggested by "evil person," "really evil act," "the evil lurking in all of us," and other such idioms. If we do this, we focus on a particular class of actions, and the motives and people that produce them, that arouse a particular moral revulsion in us. Call this the strong reading of evil: evil as atrocity (for more on this contrast see Morton [2004] and Card [2002]).Kubarych, following Peck, thinks of evil in the strong way. Most of the time at any rate: Some of the philosophers, such as Kant, that he draws on are thinking of evil in the weak way, and some of his quotations are from the German, where good/bad/evil distinctions are not drawn in the same way as in English. He explores a general explanation of evil that seems to be targeted at the psychology of extremely abhorrent actions. But, I argue, his account is in danger of collapse in either of two directions. Depending on how we interpret Kubarych's account, it could turn out that it describes all wrongdoing as evil, or, making some different choices, it could turn out that there are no really evil people.The strong reading of evil is definitely the most interesting and potentially fruitful. After all, we have no shortage of satisfying explanations of why people lie to get out of unwelcome appointments, steal to support their children or their drug habits, or defraud investors to become rich. But we do feel deeply puzzled by those who commit torture, serial murder, or genocide. We ask of these people not so much "Why did he do it?" as "How could he do it?" We feel the need of a philosophical or psychological theory that can give us even a slight handle of these people and their deeds. There are two risks associated with the project of explaining atrocity, though. The first is the risk of accepting unsatisfactory accounts, just because they purport to explain what we desperately want to understand. The second is the risk of supposing that there is a single explanation when the causes of the phenomenon are in fact too varied. On other topics these two risks have often combined to make people believe what seem to us now to be evident falsehoods. Humans have often for example wanted to know the causes of disease, and as a result have accepted blanket explanations, in terms of [End Page 257] evil spirits or lack of faith, that seem ludicrous to us now that we have a better grasp of the variety of factors that can cause our bodies to misfunction. So before asking naively "Why and how can people do these awful things?" we should ask "Is there a deeper causal unity here, beyond the fact that we react to these acts with horror?"My suspicion is that there is not much unity, that it is asking too much to want a common profile to the psychology of serial killers, or of proponents of genocide, let alone a profile that applies across these and other categories. What we can do, I believe, is describe our concept of evil in such a way that we can leave some parameters to be filled in by a large variety of objective psychological factors. Even this runs the risk that the really relevant factors cannot be forced into the role that the philosophical account requires. In... (shrink)

This paper has aimed to remedy a neglect of multi-party disputes by addressing how those involved in a two-party argument may collaborate with others who are co-present. Collaboration is a complex phenomenon. In the first place, we have seen that disputes, although initially produced by two parties, do not consist simply of two sides. Rather, given one party's displayed position, stance, or claim, another party can produce opposition by simply aligning against that position or by aligning with a counterposition. This (...) means that parties can dispute a particular position for different reasons and by different means. It is therefore possible for several parties to serially oppose another's claim without achieving collaboration. A second complexity, then, is just that collaboration is a negotiated phenomenon. For example, while it is possible for an outside party to produce an uninvited alignment display that is sympathetic to an already-stated position in a two-party dispute, the party whose position it supports can agree or disagree with that display. Thus, outsiders' uninvited alignment displays that occur subsequent to those of the insiders or principals in a two-party dispute must be considered as collaboration offers, which can be accepted or rejected. But that is not the end of it, for an outside party can offer alignments that now align with a principal party's position and then, addressing a different aspect of the principal's talk, align against it. Finally, in addition to being offered, collaboration can also be solicited. A principal in a two-party dispute solicits collaboration by inviting an outsider to display an alignment favorable to inviter's own position or to participate in a joint activity that supports that stance. Such solicits can be accepted, rejected, or, again, handled in such a way as to exhibit neutrality. Argumentative collaboration, in short, is a specific, momentary, and delicate state of affairs that is also an organized, technical achievement.The fact that the subjects for this study were children has become submerged in the formal analysis of alignment structures and collaboration. Thus, following this research, two directions can be pursued. One would be to ask how children's arguments differ from those occurring among adults. A reasoned answer would be that matters of substance or content may distinguish disputes among youthful persons from those occurring among older ones, while the forms of disputing remain relatively invariant (Maynard, 1985a, 1985b). In other words, by studying multi-party disputes among first-grade children, we learn about the structure of collaboration as a generic phenomenon among at least practitioners of standard English no matter what their age. This claim can be sustained in part because the analysis presented here depends upon deriving a priori conventional relations between utterances, rather than statistical relations between variables (Coulter, 1983). We have not examined exogenous influences — which would include the age characteristics of participants — on disputes, but rather the endogenously-produced structure of argumentative discourse. Still, the claim that patterns of collaboration are generic to children and adults can be examined with further research on multi-party disputes among different age groups.Another, more radical, research orientation, would be to consider, in any social arena where the members are identified as children, how it is that such a ‘membership category’ (Sacks, 1972) is relevant. If that query is made, then research on ‘children's arguments’ would involve investigating formal practices for exhibiting the accountable category ‘children’ as much as it would mean describing the ways that disputing is done. Those who have studied children's arguments, in Pollner's (1979) terms, have treated ‘children’ as a social fact, a ‘thing,’ rather than as a socially organized meaning, or ‘ing.’To attend to the -ing of things involves a radical modification of the attitude of daily life, for it requires attending to the processes of constitution in lieu of the product thus constituted (Pollner, 1979: 253, fn. 11).In short, we have treated arguments as the important event without also seeing how it is that the category ‘children’ is constituted as a recognizable feature of and within the research setting.

Homology is a biological sameness relation that is purported to hold in the face of changes in form, composition, and function. In spite of the centrality and importance of homology, there is no consensus on how we should understand this concept. The two leading views of homology, the genealogical and developmental accounts, have significant shortcomings. We propose a new account, the hierarchical-dependency account of homology, which avoids these shortcomings. Furthermore, our account provides for continuity between special, general, and serial (...) homology. (shrink)

"The Emperor's New Mind" by Roger Penrose has received a great deal of both praise and criticism. This review discusses philosophical aspects of the book that form an attack on the "strong" AI thesis. Eight different versions of this thesis are distinguished, and sources of ambiguity diagnosed, including different requirements for relationships between program and behaviour. Excessively strong versions attacked by Penrose (and Searle) are not worth defending or attacking, whereas weaker versions remain problematic. Penrose (like Searle) regards the notion (...) of an algorithm as central to AI, whereas it is argued here that for the purpose of explaining mental capabilities the architecture of an intelligent system is more important than the concept of an algorithm, using the premise that what makes something intelligent is not what it does but how it does it. What needs to be explained is also unclear: Penrose thinks we all know what consciousness is and claims that the ability to judge Go "del's formula to be true depends on it. He also suggests that quantum phenomena underly consciousness. This is rebutted by arguing that our existing concept of "consciousness" is too vague and muddled to be of use in science. This and related concepts will gradually be replaced by a more powerful theory-based taxonomy of types of mental states and processes. The central argument offered by Penrose against the strong AI thesis depends on a tempting but unjustified interpretation of Goedel's incompleteness theorem. Some critics are shown to have missed the point of his argument. A stronger criticism is mounted, and the relevance of mathematical Platonism analysed. Architectural requirements for intelligence are discussed and differences between serial and parallel implementations analysed. (shrink)

The present study investigates procedural learning of motor sequences in children with developmental coordination disorder and/or developmental dyslexia, typically-developing children and healthy adults with a special emphasis on the role of the nature of stimuli and the neuropsychological functions associated to final performance of the sequence. Seventy children and ten adults participated in this study and were separated in five experimental groups: TD, DCD, DD, and DCD + DD children and adults. Procedural learning was assessed with a serial reaction (...) time task that required to tap on a specific key as accurately and quickly as possible when stimuli appeared on the screen. Three types of stimuli were proposed as cues: the classical version of the SRTT with 4 squares aligned horizontally on the screen, giving visuospatial cues, and two modified versions, with 4 letters aligned horizontally on the screen and letters at the center of the screen. Reaction times during the repeated and random blocks allowed assessing three phases of learning: global learning, specific learning and retention of the sequence. Learning was considered as completed when RT evolved significantly in the three phases. Neuropsychological assessment involved, among other functions, memory and attentional functions. Our main result was that learning and retention were not influenced by the available cues in adults whereas learning improved with specific cues in children with or without neurodevelopmental disorders. More precisely, learning was not completed with L cues in children with neurodevelopmental disorders. For children with DD, learning was completed with the VS and VS + L cues whereas for children with DCD, learning was completed with combined VS + L cues. Comorbidity between DD and DCD had no more impact on procedural learning than DCD alone. These results suggest that learning depends on the nature of cues available during practice and that cues allowing learning and retention depend on the type of disorder. Moreover, selective attention was correlated with RT during retention, suggesting that this neuropsychological function is important for procedural learning whatever the available cues. (shrink)

Mesoudi et al.'s new synthesis for cultural evolution closely parallels the evolutionary synthesis of Neo-Darwinism. It too draws inspiration from population genetics, recruits other fields, and, unfortunately, also ignores development. Enculturation involves many serially acquired skills and dependencies that allow us to build a rich cumulative culture. The newer synthesis, evolutionary developmental biology, provides a key tool, generative entrenchment, to analyze them. (Published Online November 9 2006).

The paradox of the Unexpected Hanging, related prediction paradoxes, and the Sorites paradoxes all involve reasoning about ordered collections of entities: days ordered by date in the case of the Unexpected Hanging; men ordered by the number of hairs on their heads the case of the bald man version of the Sorites. The reasoning then assigns each entity a value that depends on the previously assigned value of one of the neighboring entities. The final result is paradoxical because it conflicts (...) with the obviously correct, commonsensical value. The paradox is due to the serial procedure of assigning a value based on the newly assigned value of the neighbor. An alternative procedure is to assign each value based only on the original values of neighbors - a parallel procedure. That procedure does not give paradoxical answers. (shrink)

The present paper examines the relationship between explicit and implicit memory and ultimate attainment in the native language. Two groups of native speakers of English with different levels of academic attainment (i.e., high vs. low) took part in three language tasks which assessed grammar, vocabulary and collocational knowledge, as well as phonological short-term memory (assessed using a forward digit-span task), explicit associative memory (assessed using a paired-associates task) and implicit memory (assessed using a deterministic serial reaction time task). Results (...) revealed strong relationships between phonological short-term memory and explicit associative memory on the one hand and the three language tasks on the other hand, and no relation between linguistic performance and implicit memory. Taken together, these results cast doubts on the common assumption that L1 grammar learning depends almost entirely on implicit memory and align with the claims of usage-based models of language acquisition that grammatical and lexical knowledge depend on the same cognitive mechanisms.

The aim of this work is to elucidate the meaning of 'infinity' from a phenomenological perspective, especially within the framework of Husserl’s theory of knowledge and perception. In the first chapter I firstly sketch the basics of Husserl’s phenomenology of knowledge. Thereafter I delve into the questions concerning the reduction to the 'reellen Bestand', which is hold to be the ground of verification of purports in the "Logical Investigations". I then propose an interpretation of the categorial intuition as directed to (...) the laws an 'Auffassung' follows when it organizes the sensual contents related to an object. In the second chapter I briefly expound Husserl’s phenomenology of perception and I show how perception can be hold as an intentional experience. Afterwards I concentrate on the constitution of space and of thing (Ding). I show in which sense the structures of both constitutions are dependent on the sensations and kinesthesis (i.e. proprioceptions) experienced by the subject. In the third chapter I finally deal with the problem of infinity. I face some recent interpretations of Husserl’s theory of perception according to which infinity is somehow intertwined in and even intuited through thing-perception (Dingwahrnehmung). I claim that thing-perception can not be hold as an access to infinity, i.e. no thing-perception is a perception of something as infinite. Following I show how some other kinds of sensual experience can correspond to a perception of infinity. On the base of some Husserl’s manuscripts and through a brief confrontation with Kant’s Analytic of the Sublime I sustain that infinity can be sensually intuited in the senses of limitlessness and of formlessness. I then show that categorial intuition is necessary in order to constitute the meaning of mathematical infinity, i.e. an endless whole of discrete parts. In fact, the idea of such an “entity” is dependent on the capacity of grasping the law of a serial production. In the conclusion I establish that mathematical infinity is the only kind of infinity which can not find any sensual correlate. This is due to the fact that it is a meaning composed by two contradictory prescriptions: 'reach the limitless' and 'go on without an end'. I consequently argue that the idea of infinity is grounded on sensual experience and does not need any supernatural origin. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Hegel’s Ladder, Volume I: The Pilgrimage of Reason by Henry Silton HarrisLawrence S. StepelevichHenry Silton Harris. Hegel’s Ladder, Volume I: The Pilgrimage of Reason. Pp. xvi+ 658. Volume II: The Odyssey of Spirit. Pp. xiii + 909. Indianapolis: Hackett Publishing Company, 1997. Cloth, $150.00, the set.This commentary upon Hegel’s Phenomenology of Spirit is the concentrated result of over three decades of sustained study by one of the most (...) renowned of contemporary Hegelian scholars.The Phenomenology stands in the course of philosophic history as (depending upon one’s point of view) either an opportunity or an obstacle—an unavoidable Sphinx. Both admirers and detractors of this famous work will often assign themselves or, more readily, their students, the task of reading it as a introduction to Hegel’s philosophy. However, what occurs is not usually what is intended. After a short perusal, the reader finds that the Phenomenology itself needs an introduction. This need has not been lost on scholars, and their various introductory observations, when expanded and duly annotated, are entered into the ever-growing list of commentaries upon the Phenomenology. Needless to say, given the hundreds of studies which, either in whole or in part, are devoted to commenting upon this work, there are some grand failures, as Lowenberg’s elegantly vapid Dialogues on the Phenomenology, or Heidegger’s inconclusive “critical debate with Hegel.” There are also a few successes, such as Jean Hyppolite’s Genesis and Structure. Without doubt, Harris’s commentary is a success, and surely the most successful of all Anglophone commentaries upon the Phenomenology. [End Page 473]Hegel’s Ladder, which assumes a learned readership, embarks upon the same long and tortured path facing any reader of the Phenomenology. It is no small thing to follow where one thinks Hegel leads, as he had a somewhat perverse tendency to avoid both clarifying examples and a tendency to, as J. N. Findlay described it, “wanton obscurity.” To make matters worse, there is also the complex ordering of the text itself, a palimpsest character which has led more than a few commentators to take the work as a disorderly juvenalia, best left ignored in favor of the more lucid Encyclopaedia. And finally, there is also the extratextual matter of whether or not one “buys into” Hegel’s thought—which Harris does. In any case, a superficial reading will not do, and readers will be reminded of Hegel’s own “path of despair” when they follow the course of Harris’s 1,500-page commentary. It is not an “easy read,” nor could it be.Professor Harris is well aware of the problems confronting any commentator, but addresses them in an way which would assure the reader that the commentary is directly linked to the text, and does not simply follow “paths of one’s own, offering variations, elaborations, and applications instead of faithful analysis” (xii). To this end, a “logical commentary” is developed, one which follows a serial paragraph-by-paragraph analysis of the text. Each paragraph-analysis is referenced to the Phenomenology, which allows the reader a direct reference to Hegel’s own words. These “safe” and constrained analytic paragraphs are each followed by an extensive and free-ranging commentary. The intention of this procedure is not only to assure the reader that Harris’s commentary is textually grounded, but to convince the reader that Harris’s contention regarding the nature of the Phenomenology is correct—that it is a profoundly cohesive and extended logical argument. In short, for Harris, the Phenomenology is exactly what what Hegel claimed it to be: a science of experience. Most commentators have not accepted this claim of either the unity or the logical course of the text, but this “received view” is, for Harris, the “view that I want to challenge and, if possible, to overthrow. If I am right, an acceptably continuous chain of argument, paragraph by paragraph, ought to be discoverable in the text” (xii).In the total context of Hegel’s philosophy, Harris understands the Phenomenology to be the “necessary preamble to speculative logic.” Once this is accepted, then “we ought to know at once, by the simplest of...

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Hegel’s Ladder, Volume I: The Pilgrimage of Reason by Henry Silton HarrisLawrence S. StepelevichHenry Silton Harris. Hegel’s Ladder, Volume I: The Pilgrimage of Reason. Pp. xvi+ 658. Volume II: The Odyssey of Spirit. Pp. xiii + 909. Indianapolis: Hackett Publishing Company, 1997. Cloth, $150.00, the set.This commentary upon Hegel’s Phenomenology of Spirit is the concentrated result of over three decades of sustained study by one of the most (...) renowned of contemporary Hegelian scholars.The Phenomenology stands in the course of philosophic history as (depending upon one’s point of view) either an opportunity or an obstacle—an unavoidable Sphinx. Both admirers and detractors of this famous work will often assign themselves or, more readily, their students, the task of reading it as a introduction to Hegel’s philosophy. However, what occurs is not usually what is intended. After a short perusal, the reader finds that the Phenomenology itself needs an introduction. This need has not been lost on scholars, and their various introductory observations, when expanded and duly annotated, are entered into the ever-growing list of commentaries upon the Phenomenology. Needless to say, given the hundreds of studies which, either in whole or in part, are devoted to commenting upon this work, there are some grand failures, as Lowenberg’s elegantly vapid Dialogues on the Phenomenology, or Heidegger’s inconclusive “critical debate with Hegel.” There are also a few successes, such as Jean Hyppolite’s Genesis and Structure. Without doubt, Harris’s commentary is a success, and surely the most successful of all Anglophone commentaries upon the Phenomenology. [End Page 473]Hegel’s Ladder, which assumes a learned readership, embarks upon the same long and tortured path facing any reader of the Phenomenology. It is no small thing to follow where one thinks Hegel leads, as he had a somewhat perverse tendency to avoid both clarifying examples and a tendency to, as J. N. Findlay described it, “wanton obscurity.” To make matters worse, there is also the complex ordering of the text itself, a palimpsest character which has led more than a few commentators to take the work as a disorderly juvenalia, best left ignored in favor of the more lucid Encyclopaedia. And finally, there is also the extratextual matter of whether or not one “buys into” Hegel’s thought—which Harris does. In any case, a superficial reading will not do, and readers will be reminded of Hegel’s own “path of despair” when they follow the course of Harris’s 1,500-page commentary. It is not an “easy read,” nor could it be.Professor Harris is well aware of the problems confronting any commentator, but addresses them in an way which would assure the reader that the commentary is directly linked to the text, and does not simply follow “paths of one’s own, offering variations, elaborations, and applications instead of faithful analysis” (xii). To this end, a “logical commentary” is developed, one which follows a serial paragraph-by-paragraph analysis of the text. Each paragraph-analysis is referenced to the Phenomenology, which allows the reader a direct reference to Hegel’s own words. These “safe” and constrained analytic paragraphs are each followed by an extensive and free-ranging commentary. The intention of this procedure is not only to assure the reader that Harris’s commentary is textually grounded, but to convince the reader that Harris’s contention regarding the nature of the Phenomenology is correct—that it is a profoundly cohesive and extended logical argument. In short, for Harris, the Phenomenology is exactly what what Hegel claimed it to be: a science of experience. Most commentators have not accepted this claim of either the unity or the logical course of the text, but this “received view” is, for Harris, the “view that I want to challenge and, if possible, to overthrow. If I am right, an acceptably continuous chain of argument, paragraph by paragraph, ought to be discoverable in the text” (xii).In the total context of Hegel’s philosophy, Harris understands the Phenomenology to be the “necessary preamble to speculative logic.” Once this is accepted, then “we ought to know at once, by the simplest of...

An expanding media universe confronts readers, viewers, and users with an abundance of media content that, for the most part, will not be used by the audience, and will, in many cases, not even be considered for use. Selecting what to use and not to use is functional in avoiding information overload or ‘technostress’, but, at the same time, necessary to make use of the media environment. The selection of media initiates gratifications, serves particular functions, enables certain effects, all depending (...) on the perspective. Media use and selectivity constitute a field of remarkable tradition in communication research. The question how individuals deal with media and why they use certain media content has been in the focus of communication research from the very beginning of empirical media research; since Lazarsfeld and his colleagues conducted their radio research projects, which included Herzog's widely cited study on daytime serial listeners. Thinking about media use reached a first prime with the emergence of Uses and Gratifications approaches; an abundance of studies about ‘what people do with the media’ have been published during the golden years of Uses and Gratifications in the 1970s and 1980s. Bryant and Miron identified Uses and Gratifications – along with Agenda Setting – as the approach most frequently used in three communication journals from 1956 through 2000. (shrink)
