If the decades of the forties through the sixties were dominated by discussion of Hempel's “covering law“ explication of explanation, that of the seventies was preoccupied with Salmon's “statistical relevance” conception, which emerged as the principal alternative to Hempel's enormously influential account. Readers of Wesley C. Salmon's Scientific Explanation and the Causal Structure of the World, therefore, ought to find it refreshing to discover that its author has not remained content with a facile defense of his previous investigations; on the (...) contrary, Salmon offers an original account of different kinds of explications, advances additional criticisms of various alternative theories, and elaborates a novel “two-tiered“ analysis of explanation that tacitly depends upon a “two-tiered” account of homogeneity. Indeed, if the considerations that follow are correct, Salmon has not merely refined his statistical relevance account but has actually abandoned it in favor of a “causal/mechanistic“ construction. This striking development suggests that the theory of explanation is likely to remain as lively an arena of debate in the eighties as it has been in the past. (shrink)

In traditional linguistic accounts of context, one thinks of the immediate features of a speech situation, that is, a situation in which an expression is uttered. Thus, features such as time, location, speaker, hearer and preceding discourse are all parts of context. But context is a wider and more transcendental notion than what these accounts imply. For one thing, context is a relational concept relating social actions and their surroundings, relating social actions, relating individual actors and their surroundings, and relating (...) the set of individual actors and their social actions to their surroundings. (shrink)

This book departs from the premise that context represents a complex relational configuration which can no longer be conceived as an analytic prime but rather requires a parts-whole perspective to capture its inherent dynamism. The edited volume presents a collection of papers which examine the connectedness between context, contextualization and entextualization. They address the questions how meaning and speech acts are situated in context, how both are influenced by context, how context influences speech acts and meaning, how context is imported (...) into the discourse, and how context is entextualized in discourse. The papers cover institutional and non-institutional contexts, the language of Greek laws, political discourse, confrontational media discourse and task-oriented face-to-face and back-to-back interactions. They reflect current moves in pragmatics and discourse analysis to cross disciplinary and methodological boundaries by integrating relevant premises and insights, in particular cognition, adaptive action, negotiation of meaning, sequentiality, recipient design and genre.

The social exchange theory of reasoning, which is championed by Leda Cosmides and John Tooby, falls under the general rubric “evolutionary psychology” and asserts that human reasoning is governed by content-dependent, domain-specific, evolutionarily-derived algorithms. According to Cosmides and Tooby, the presumptive existence of what they call “cheater-detection” algorithms disconfirms the claim that we reason via general-purpose mechanisms or via inductively acquired principles. We contend that the Cosmides/Tooby arguments in favor of domain-specific algorithms or evolutionarily-derived mechanisms fail and that the notion (...) of a social exchange rule, which is central to their theory, is not correctly characterized. As a consequence, whether or not their conclusion is true cannot be established on the basis of the arguments they have presented. (shrink)

Science aims at the discovery of general principles of special kinds that are applicable for the explanation and prediction of the phenomena of the world in the form of theories and laws. When the phenomena themselves happen to be general, the principlesinvolved assume the form of theories; and when they are p- ticular, they assume the form of general laws. Theories themselves are sets of laws and de nitions that apply to a common domain, which makes laws indispensable to science. (...) Understanding science thus depends upon understanding the nature of theories and laws, the logical structure of explanations and predictions based upon them, and the principles of inference and decision that apply to theories and laws. Laws and theories can differ in their form as well as in their content. The laws of quantum mechanics are indeterministic, for example, while those of classical mechanics are deterministic instead. The history of science re ects an increasing role for probabilities as properties of the world but also as measures of evidential support and as degrees of subjective belief. Our purpose is to clarify and illuminate the place of probability in science. (shrink)

The development of science has been a distinctive feature of human history in recent times, especially in the seventeenth and eighteenth centuries. In light of the problems that define the philosophy of science today, James Fetzer provides a foundation for inquiry into the nature of science, the history of science, and the relationship between the two. In Philosophy of Science, Fetzer investigates the aim and methods of empirical science and examines the importance of methodological commitments to the study (...) of science and the significance of interpretations of probability for understanding laws of nature and scientific explanations. This book offers a welcome framework for investigating the most recent work and the most promising solutions to the central problems that arise within this discipline. The result is a timely introduction to an increasingly important field. -- Publisher description. (shrink)

The purpose of this paper is to explore three alternative frameworks for understanding the nature of language and mentality, which accent syntactical, semantical, and pragmatical aspects of the phenomena with which they are concerned, respectively. Although the computational conception currently exerts considerable appeal, its defensibility appears to hinge upon an extremely implausible theory of the relation of form to content. Similarly, while the representational approach has much to recommend it, its range is essentially restricted to those units of language that (...) can be understood in terms of undefined units. Thus, the only alternative among these three that can account for the meaning of primitive units of language is one emphasizing the basic role of skills, habits, and tendencies in relating signs and dispositions.

In lieu of an abstract, here is a brief excerpt of the content:Republicanism, Religion, and Machiavelli’s Savonarolan MomentMarcia L. ColishMachiavelli’s readers often take at face value his claim that Christianity has weakened Italy’s civic spirit and martial valor, leaving it open to priestcraft and foreign invasion. Some scholars see this critique of Christianity as an expression of the irreligious, immoral, neopagan, or scientific Machiavelli, making it the chief index of his modernity. 1 One subset within this group treats Machiavelli’s [End (...) Page 597] anthropology as a secularized version of Augustine on original sin, absent an Eden behind it and a redemption before it. 2 Another view of Machiavelli on religion sees him as treating religion, whatever its teachings, functionally, as an instrument promoting desirable political behavior. 3 This is why they regard [End Page 598] Machiavelli as original and modern; although Maury D. Feld notes rightly that Machiavelli is here simply imitating the ancient Roman historians, who all treat religion in just this way. 4 For some proponents of the functionalist interpretation, it does not preclude Christian belief on Machiavelli’s part. For them his brief is not against Christianity itself but against clericalism, the papacy, and Christianity as it is currently interpreted. 5 Still others recognize Machiavelli’s acceptance of signs and portents, saintly behavior and miracles, and other indices of God’s existence and action in human history. They also note Machiavelli’s praise of biblical leaders seen as divinely inspired and his inclusion of them among the founders of religions and states who head his list of heroes. 6 Going farther, some scholars argue that Machiavelli was a conventional, if not an ardent or impeccable, Christian, who joined a religious confraternity before which he preached his Exhortation to Penitence, and the apparent recipient of the last rites of his church after a deathbed confession. 7 [End Page 599]Can these conflicting assessments of Machiavelli and religion be integrated? To some extent, yes. Once, that is, we consider a number of issues not always brought to bear on this question. Machiavelli recognizes that the foreigners who have overrun Italy and deprived Florence of the republic he had served are as Christian as the Italians. At home and abroad, their Christianity has not undermined their military strength or the civic virtue Machiavelli associates with republics. Within contemporary Florence there were three kinds of republicanism on offer, for those unhappy with the Medici restoration of 1512. One group sought to restore the pre-Medici governo stretto constitution dominated by the ottimati. Their opponents defended governo largo republicanism. Machiavelli advocated this type of polity, informed by his reading of ancient history and his assessment of human nature. But another, competing version of governo largo was put forth by Girolamo Savonarola during the Dominican friar’s stormy career as de facto head of the Florentine state from 1494 to 1498. Savonarola’s republican theory combined a number of ideas that Machiavelli loathed: the appeal to the Venetian Great Council as a model, the wish to purge Florence of her sins so that she could serve as the New Jerusalem in the coming apocalypse, and the notion that governo largo was a means to these religious ends, since the more broad-based the government, the more readily could it legislate and enforce moral reform. And, far from self-destructing after the friar’s ashes had been strewn on the Arno, Savonarolan republicanism continued to draw support from a diverse and substantial group of Florentines. Equally alarming, the agents [End Page 600] of this protracted Savonarolan moment seemed to have preempted Machiavelli’s own anticlerical, antipapal, antioligarchic, and antiMedicean positions, as well as a theory of governo largo. If we foreground Machiavelli’s desire to defend his own version of republicanism by undermining the Savonarolan alternative and if we recall that he treats Christianity positively in other contexts, it becomes possible to read those passages where he criticizes Christianity as practiced in Italy as texts with an antiSavonarolan subtext. Read this way, they are not incompatible with his acceptance of Christianity as true or as politically constructive elsewhere. In approaching this topic, we should also remember the longstanding associations that bound Christianity to politics and warfare.Addressing this last point... (shrink)

The idea that human thought requires the execution of mental algorithms provides a foundation for research programs in cognitive science, which are largely based upon the computational conception of language and mentality. Consideration is given to recent work by Penrose, Searle, and Cleland, who supply various grounds for disputing computationalism. These grounds in turn qualify as reasons for preferring a non-computational, semiotic approach, which can account for them as predictable manifestations of a more adquate conception. Thinking does not ordinarily require (...) the execution of mental algorithms, which appears to be at best no more than one rather special kind of thinking. (shrink)

The notion of program verification appears to trade upon an equivocation. Algorithms, as logical structures, are appropriate subjects for deductive verification. Programs, as causal models of those structures, are not. The success of program verification as a generally applicable and completely reliable method for guaranteeing program performance is not even a theoretical possibility.

Luciano Floridi (2003) offers a theory of information as a “strongly semantic” notion, according to which information encapsulates truth, thereby making truth a necessary condition for a sentence to qualify as “information”. While Floridi provides an impressive development of this position, the aspects of his approach of greatest philosophical significance are its foundations rather than its formalization. He rejects the conception of information as meaningful data, which entails at least three theses – that information can be false; that tautologies are (...) information; and, that “It is true that...” is non-redundant – appear to be defensible. This inquiry offers various logical, epistemic, and ordinary-language grounds to demonstrate that an account of his kind is too narrow to be true and that its adoption would hopelessly obscure crucial differences between information, misinformation, and disinformation.

This series will include monographs and collections of studies devoted to the investigation and exploration of knowledge, information and data-processing systems of all kinds, no matter whether human, (other) animal or machine. Its scope is intended to span the full range of interests from classical problems in the philosophy of mind and phi losophical psychology through issues in cognitive psychology and socio biology (concerning the mental capabilities of other species) to ideas related to artificial intelligence and computer science. While primary (...) emphasis will be placed upon theoretical, conceptual and epistemologi cal aspects of these problems and domains, empirical, experimental and methodological studies will also appear from time to time. Among the most challenging and difficult projects within the scope of artificial intelligence is the development and implementation of com puter programs suitable for processing natural language. Our purpose in compiling the present volume has been to contribute to the foundations of this enterprise by bringing together classic papers devoted to crucial problems involved in understanding natural language, which range from issues of formal syntax and logical form to those of possible-worlds and situation semantics. The book begins with a comprehensive introduc tion composed by Jack Kulas, the senior editor of this work, which pro vides a systematic orientation to this complex field, and ends with a selected bibliography intended to promote further research. If our efforts assist others in dealing with these problems, they will have been worthwhile. J. H. F. (shrink)

The contributions to this special collection concern issues and problems discussed in or related to the work of Wesley C. Salmon. Salmon has long been noted for his important work in the philosophy of science, which has included research on the interpretation of probability, the nature of explanation, the character of reasoning, the justification of induction, the structure of space/time and the paradoxes of Zeno, to mention only some of the most prominent. During a time of increasing preoccupation with historical (...) and sociological approaches to under standing science (which characterize scientific developments as though they could be adequately analysed from the perspective of political movements, even mistaking the phenomena of conversion for the rational appraisal of scientific theories), Salmon has remained stead fastly devoted to isolating and justifying those normative standards distinguishing science from non-science - especially through the vindi cation of general principles of scientific procedure and the validation of specific examples of scientific theories - without which science itself cannot be (even remotely) adequately understood. In this respect, Salmon exemplifies and strengthens a splendid tradi tion whose most remarkable representatives include Hans Reichenbach, Rudolf Carnap and Carl G. Hempel, all of whom exerted a profound influence upon his own development. (shrink)

Alcohol use has long been assumed to alter cognition via attentional processes. To better understand the cognitive consequences of intoxication, the present study tested the effects of moderate intoxication on attentional processing using complex working memory capacity span tasks and a change blindness task. Intoxicated and sober participants were matched on baseline WMC performance, and intoxication significantly decreased performance on the complex span tasks. Surprisingly, intoxication improved performance on the change blindness task. The results are interpreted as evidence that intoxication (...) decreases attentional control, causing either a shift towards more passive processing and/or a more diffuse attentional state. This may result in decreased performance on tasks where attentional control or focus are required, but may actually facilitate performance in some contexts. (shrink)
