In the preface to this book Stephen Toulmin recalls how Wittgenstein's later work appeared to his English students "as unique and extraordinary as the Tractatus had appeared to Moore." "Meanwhile," he recalls, "for our own part, we struck Wittgenstein as intolerably stupid, and he was sometimes in despair about getting us to grasp what he was talking about." Toulmin suggests that this "mutual incomprehension" was due to a "culture clash: the clash between a Viennese thinker whose whole mind had been (...) formed in a post-Kantian environment, and an audience of students who came to him with attitudes and preoccupations shaped by the neo-Humean empiricism of Moore, Russell and their associates." Engel's book is meant primarily to show that Wittgenstein's thought grows out of the Kantian philosophy, but not that it is simply derived from Kant. Rather, according to Engel, Wittgenstein was the first to see the full value of the insights of Kant and Schopenhauer. Engel bases his argument on the Blue Book. According to Engel the argument of the Blue Book comprehends two divergent theories of the origin of metaphysics. These two theories are represented in Engel's book by Ayer and Lazerowitz. For Ayer metaphysics is grounded in the inherently deceptive character of language; and the way to overcome metaphysics is but to be attentive to language. Lazerowitz, on the other hand, attempts to explain why it is that language is deceptive. Lazerowitz's argument as presented by Engel requires as a premise the proposition that the deceptions of language are not that intrinsically difficult to see through, or that metaphysical arguments are obviously "innovations." And therefore the origin of metaphysics must be sought outside of the structure of language. Lazerowitz locates the root of metaphysics in the passions, specifically, in fear--in the fear of change which is ultimately the fear of death. Engel sees each of these positions as in its way legitimate but essentially partial. Wittgenstein's thought is thus more profound than that which is derived from it. It is precisely this awareness of the necessity for both kinds of explanation that Wittgenstein, according to Engel, inherited from the tradition of Kantian metaphysics: in the first Critique's seeking both to account for the impossibility of metaphysics while, at the same time, arguing for the necessity of metaphysics as a natural disposition or arguing for the necessity of a "will to metaphysics." While Engel's argument is not as clear or thorough as it ought to be, his thesis, that Wittgenstein's work is not simply a "repudiation of our philosophical tradition, but rather is its proper twentieth-century continuation," is--in the main--convincing. The book is worth reading.--J. W. S. (shrink)

The "purpose of this book is to examine those conceptions of metaphysics prevalent in seventeenth- and eighteenth-century British philosophic thought." The book traces empiricist conceptions of metaphysics from Bacon onward to Reid and Stewart. Armstrong's treatment of Bacon is the most controversial chapter in his book. Armstrong opposes the widely held view that Bacon was essentially a mechanist. Armstrong argues that the texts usually cited to show that Bacon held the mechanical philosophy are at best ambiguous; while, on the other (...) hand, there are Bacon's clear statements on metaphysics as a science of formal causes. It is on the basis of these latter statements that Armstrong argues that Bacon's metaphysics is essentially Aristotelian. In the language of the tradition, Armstrong's interpretation of Bacon might be summed up as follows: Bacon understood metaphysics to be the science of formal causality; that is, he understood metaphysics as the science of Being as Being. Consequently, according to Armstrong, a characteristic empiricist metaphysics first appears in the thought of Hobbes. In Hobbes the mechanical philosophy is established as the science of nature, as the science of Being as Being. Metaphysics becomes defined once and for all within British Empiricism in opposition to physics or the materialist ontology. Beginning with Hobbes metaphysics is understood within British Empiricism as either epistemology or theology. This historical study should prove of interest to those who, brought up in the tradition of British Empiricism, are rediscovering the traditional questions of metaphysics.--J. W. S. (shrink)

This work is intended to be a "philosophical analysis" of certain problems encountered by the social sciences. The aim of the book is to "help redirect modern social science from some important theoretical mistakes." According to Kaplan most of our knowledge rests on common sense. It is the mark of common sense knowledge that it is not self-conscious, that it does not engage in a critique of its own possibility. The realm of the philosophy of history, of social science, and (...) of science is opened up through the attempt at "self-consciousness concerning the limits of the various processes by which knowledge is obtained." Kaplan accepts the proposition that the "framework within which knowledge occurs can never be included in knowledge itself," that the framework within which knowledge is acquired cannot be transcended. It might appear from his acceptance of this proposition that Kaplan would accept radical historicism. This is not the case. It is a primary intention of Kaplan to suggest that we can state the standpoint from which perspectival knowing exists, what it depends upon, and what it leaves out of account. Kaplan sees a measure of transcendence being achieved through the comprehension of different perspectives. However, he explicitly rejects the possibility of a true consciousness which would be the result of a single correct perspective on the world. The book has several major flaws. The greatest is the absence of sustained argument. The author fails to give evidence for the major propositions of the book. Usually a footnote to previous writings of his is offered as substitute for argument. Another major flaw of the book stems from Kaplan's understanding of what is characteristically human in the terms of systems analysis. To one not convinced in advance of the adequacy of this language to the task of understanding man, Kaplan's work will appear to suffer from an ill-conceived use of technical jargon.--J. W. S.

This collection of essays in moral philosophy has as its intended mark of distinction the fact that moral problems of the moment are the themes of the essays. The chapter headings indicate this contemporary concern: Abortion, Sex, Human Rights and Civil Disobedience, Criminal Punishment, Violence and Pacifism, War and Suicide and Death. There are essays by: Paul Ramsey, Philippa Foot, Jonathan Bennett, Thomas Nagel, Sara Ruddick, Richard Wassenstrom, [[sic]] John Rawls, R. M. Dworkin, William Kneale, H. L. A. Hart, J. (...) R. Lucas, Newton Carver, Jan Narveson, G. E. M. Anscombe, R. M. Hare, R. F. Holland, Mary Mothersill. One might well be inclined to agree with the editor's opposition to such philosophizing about morality which abstracts from the moral problems of one's own life. A purely theoretical approach to the study of morality would almost appear contradictory. However, it is necessary to express grave reservations about such a collection of essays as this. While the arguments of the essays are thoughtful and somewhat uncommon, the conclusions of the essays, as a rule, do not differ from "advanced" liberal opinions. In other words, the essays do not challenge students' opinions. The reading of these essays will but confirm the young in their prejudices. The problems the essays are concerned with are real problems; and it is a defect of the book that with the single exception of the chapter on Abortion no real opposing arguments are presented.--J. W.

Three experiments explore the role of working memory in motor skill acquisition and performance. Traditional theories postulate that skill acquisition proceeds through stages of knowing, which are initially declarative but later procedural. The reported experiments challenge that view and support an independent, parallel processing model, which predicts that procedural and declarative knowledge can be acquired separately and that the former does not depend on the availability of working memory, whereas, the latter does. The behaviour of these two processes was manipulated (...) by providing or withholding visual (and auditory) appraisal of outcome feedback. Withholding feedback was predicted to inhibit the use of working memory to appraise success and, thus, prevent the formation of declarative knowledge without affecting the accumulation of procedural knowledge. While the first experiment failed to support these predictions, the second and third experiments demonstrated that procedural and declarative knowledge can be acquired independently. It is suggested that the availability of working memory is crucial to motor performance only when the learner has come to rely on its use. (shrink)

The authors' novel approach to some interesting mathematical concepts - not normally taught in other courses - places them in a historical and philosophical setting. Although primarily intended for mathematics undergraduates, the book will also appeal to students in the sciences, humanities and education with a strong interest in this subject. The first part proceeds from about 1800 BC to 1800 AD, discussing, for example, the Renaissance method for solving cubic and quartic equations and providing rigorous elementary proof that certain (...) geometrical problems posed by the ancient Greeks cannot be solved by ruler and compass alone. The second part presents some fundamental topics of interest from the past two centuries, including proof of G del's incompleteness theorem, together with a discussion of its implications. (shrink)

Governments and other food system actors from the private sector, civil society, research and education institutions are being called upon to work together to enhance the sustainability, resilience and inclusiveness of food systems. The analysis presented in this study provides an insight into the process and direction of food system transformation, and the key capabilities required. It portrays the interplay of different internal and external dynamics combined with the capacity of food system actors to connect, forge alliances and commit to (...) specific actions that has enabled countries to move towards a more sustainable food system.

Aims and hypothesesIn an environment of absolute silence, researchers have found many of their participants to perceive phantom sounds. With this between-subject experiment, we aimed to elaborate on these research findings, and specifically investigated whether–in line with the fear-avoidance model of tinnitus perception and reactivity–fear or level of perceived threat influences the incidence and perceptual qualities of phantom sound percepts in an anechoic room. We investigated the potential role of individual differences in anxiety, negative affect, noise sensitivity and subclinical hearing (...) loss. We hypothesized that participants who experience a higher level of threat would direct their attention more to the auditory system, leading to the perception of tinnitus-like sounds, which would otherwise be subaudible, and that under conditions of increased threat, narrowing of attention would lead to perceptual distortions.MethodsIn total, N = 78 normal-hearing volunteers participated in this study. In general, the study sample consisted of young, mostly female, university students. Their hearing was evaluated using gold-standard pure tone audiometry and a speech-in-noise self-test, which is a sensitive screening test to identify subclinical hearing loss. Prior to a four-minute stay in an anechoic room, we randomized participants block design-wise in a threat and no-threat condition. Participants in the threat condition were deceived about their hearing and were led to believe that staying in the room would potentially harm their hearing temporarily. Participants were asked whether they perceived sounds during their stay in the room and rated the perceptual qualities of sound percepts. They were also asked to fill-out standardized questionnaires measuring anxiety, affect and noise sensitivity. The internal consistency of the questionnaires used was verified in our study sample and ranged between α = 0.61 and α = 0.90.ResultsIn line with incidence rates reported in the literature, 74% of our participants reported having heard tinnitus-like sounds in the anechoic room. Speech-in-noise identification ability was comparable for both groups of participants. The experimental manipulation of threat was proven to be effective, as indicated by significantly higher scores on a Threat Manipulation Checklist among participants in the threat condition as compared to those in the no-threat condition. Nevertheless, participants in the threat condition were as likely to report tinnitus percepts as participants in the no-threat condition, and tinnitus percepts were not rated as being louder or more unpleasant as a function of level of threat. For participants who did experience tinnitus percepts, a higher level of threat was associated with a higher degree of experienced unpleasantness. These associations were absent in those who did not experience tinnitus. Higher negative affect was only slightly associated with higher ratings of tinnitus unpleasantness.ConclusionWhereas our threat manipulation was successful in elevating the level of fear, it did not contribute to a higher percentage of participants perceiving tinnitus-like sounds in the threat condition. However, higher levels of perceived threat were related to a higher degree of perceived tinnitus unpleasantness. The findings of our study are drawn from a rather homogenous participant pool in terms of age, gender, and educational background, challenging conclusions that are applicable for the general population. Participants generally obtained normophoric scores on independent variables of interest: they were low anxious, low noise-sensitive, and there was little evidence for the presence of subclinical hearing loss. Possibly, there was insufficient variation in scores to find effects. (shrink)
