This paper develops a theory of belief and belief ascription which retains the core of the received Propositionalist theory but which, unlike the Propositionalist theory, is compatible with both Direct Reference and Individualism about belief. The focus is on developing an alternative analysis of belief ascriptions, drawing out its implications, and applying it to some standard problems. On that analysis, ascriptions involving directly referential embedded terms are seen as roughly characterizing, but not specifying, the contents of beliefs. This feature is (...) what makes it possible to maintain both Direct Reference and Individualism. (shrink)

In this paper, I develop two criticisms of L. Jonathan Cohen's influential a priori argument that human irrationality cannot be experimentally demonstrated. The first is that the argument depends crucially on the concept of a normal human but that no such concept suitable for Cohen's purposes is available. The second is that even if his argument were granted, his thesis of an unimpeachable human capacity for reasoning is not a defense of human reasoning, but rather amounts to the claim that (...) we cannot make any meaningful evaluative claims about human reasoning whatsoever.

We introduce a new operator, called rational evaluation, in belief change. The operator evaluates new information according to the agent’s core beliefs, and then exports the plausible part of the new information. It belongs to the decision module in belief change. We characterize rational evaluation by axiomatic postulates and propose two functional constructions for it, based on the well-known constructions of kernel sets and remainder sets, respectively. The main results of the paper are two representation theorems with respect to the (...) two functional constructions. We also compare and connect the evaluation operator with some related operators in belief revision, including contraction, set contraction, and prioritized multiple revision. (shrink)

First we show that the classical two-player semantic game actually corresponds to a three-valued logic. Then we generalize this result and give an n-player semantic game for an n + 1-valued logic with n binary connectives, each associated with a player. We prove that player i has a winning strategy in game G if and only if the truth value of φ is $t_i $ in the model M, for 1 ≤ i ≤ n; and none of the players has (...) a winning strategy in G if and only if the truth value of φ is $t_o $ in M.

This contributed volume includes both theoretical research on philosophical logic and its applications in artificial intelligence, mostly employing the concepts and techniques of modal logic. It collects selected papers presented at the Second Asia Workshop on Philosophical Logic, held in Guangzhou, China in 2014, as well as a number of invited papers by specialists in related fields. The contributions represent pioneering philosophical logic research in Asia.

This edited book focuses on non-classical logics and their applications, highlighting the rapid advances and the new perspectives that are emerging in this area. Non-classical logics are logical formalisms that violate or go beyond classical logic laws, and their specific features make them particularly suited to describing and reason about aspects of social interaction. The richness and diversity of non-classical logics mean that this area is a natural catalyst for ideas and insights from many different fields, from information theory to (...) game theory and business science. This volume is the post-proceedings of the 8th International Conference on Logic and Cognition, held at Sun Yat-Sen University Institute of Logic and Cognition in Guangzhou, China in December 2016. The conference series started in 2001, and is organized by the ILC, often in collaboration with various international research groups. This eighth installment was jointly organized by ILC and Alessandra Palmigiano's Applied Logic research group. The conference series aims to foster the development of effective logical tools to study social behavior from a philosophical, cognitive and formal perspective in order to challenge the field of logic in ways that open up new and exciting research directions.

Wittgenstein’s Picture Theory of language holds that one fact can represent another, and that propositions are pictures of states of affairs. What makes a fact into a picture of a given s tate of affairs are the correlations between picture elements and objects and the correlations between relations among picture elements and relations among objects. But a problem sometimes raised is that propositions can’t be pictures, as pictures—unlike propositions—do not say anything. An interpretation (e.g. Anscombe’s) holds that the above‐mentioned correlations (...) do make the picture into a proposition. But this neither handles the objection, nor is it Wittgenstein’s view. Further, Wittgenstein’s own account faces serious difficulties in addressing these issues, and the Anscombe‐type interpretation obscures this fact. (shrink)

The Direct Reference account of the semantics of singular terms is widely assumed to be inconsistent with the traditional Individualist account of psychological states. Because of this assumption, and because of the weight of the evidence for Direct Reference, Anti-Individualism has found supporters despite its counterintuitiveness. In this dissertation, it is argued that Direct Reference and Individualism are not genuinely inconsistent, but that the inconsistency emerges only with the additional assumption of Propositionalism--the orthodox, proposition-based framework for understanding thought and language. (...) Consequently, it is not necessary to endorse Anti-Individualism in order to accept Direct Reference, so long as Propositionalism is accepted only in an attenuated form, if at all. ;It is argued that the best strategy for resolving the inconsistency is to retain all of Propositionalism apart from the Relational Analysis of belief ascriptions. An alternative analysis--the Quantified Relational Analysis --is developed and motivated. According to QRA, an ascription of the form X believes that S attributes the property of believing some member of the class of propositions containing the proposition that S and finer-grained versions of it. QRA is extended also to de re belief locutions. The conjunction of Direct Reference, Individualism, and the remnants of Propositionalism plus QRA is termed Russellian Non-Parallelism. ;Like all Direct Reference theories, Russellian Non-Parallelism has the consequence that co-referring names and other genuine terms are freely substitutable for each other, despite the datum that ordinary speakers intuitively regard such substitutions in belief contexts as suspect. These intuitions are accounted for both pragmatically and semantically. The pragmatic explanation specifies a mechanism whereby the audience sometimes infers from the choice of genuine terms the subject's way of thinking of the objects involved. The semantic explanation motivates an idiomatic reading of ascriptions, on which, under certain circumstances, the choice of co-referring terms in ascriptions literally indicates different belief contents. Russellian Non-Parallelism is then applied to enhanced substitution puzzles and to some other traditional problems, such as the contingent a priori. Finally there is a discussion of pertinent contemporary literature. (shrink)

We associate the semantic game with chance moves conceived by Blinov with Blamey’s partial logic. We give some equivalent alternatives to the semantic game, some of which are with a third player, borrowing the idea of introducing the pseudo-player called Nature in game theory. We observe that IF propositional logic proposed by Sandu and Pietarinen can be equivalently translated to partial logic, which implies that imperfect information may not be necessary for IF propositional logic. We also indicate that some independent (...) quantifiers can be regarded as dependent quantifiers of indeterminate sequence, using the interjunction connective in partial logic. We conclude our paper by indicating some further research in a more general setting. (shrink)

In this important study D. M. Armstrong offers a comprehensive system of analytical metaphysics that synthesises but also develops his thinking over the last twenty years. Armstrong's analysis, which acknowledges the 'logical atomism' of Russell and Wittgenstein, makes facts the fundamental constituents of the world, examining properties, relations, numbers, classes, possibility and necessity, dispositions, causes and laws. All these, it is argued, find their place and can be understood inside a scheme of states of affairs. This is a comprehensive and (...) rigorously this-worldly account of the most general features of reality, argued from a distinctive philosophical perspective, and it will appeal to a wide readership in analytical philosophy.

Awareness logic is a type of belief logic in which an agent's beliefs are restricted to those sentences that the agent is aware of. Awareness logic is a successful way to circumvent the problem of omniscience so that actual belief is modelled in a reasonable way. In this paper, we suggest a new method modelling awareness and actual belief by using two-dimensional logics. We show that the two-dimensional logics are flexible tools. Different types of concepts of awareness can be easily (...) modelled by this method. (shrink)

Celebrated for disproving the traditional view that lack of oxygen at birth (perinatal asphyxia) contributes significantly to cerebral palsy, a 1986 New England Journal of Medicine article by Karin Nelson and Jonas Ellenberg engineered a new consensus in the medical community: that lack of oxygen at birth rarely causes cerebral palsy. We demonstrate that the article's central argument relies on straightforwardly fallacious statistical reasoning, and we discuss significant implications -- e.g. how carefully fetuses are monitored during labor and delivery, expert (...) testimony in malpractice cases, and public policy decisions.

Medical argumentation in non-Western societies has attracted little attention. In line with the pragma-dialectical approach to the study of argumentation, this article identifies a prototypical argumentative pattern in Chinese medical consultations. In addition to institutional preconditions, whose relevance to the argumentative pattern has been well cited, a factor that may be equally important has remained unnoticed: the preference for certain drugs, treatments or therapeutic measurements on the basis of folk interpretations of medical phenomena in individual ethnic groups. These preferences may (...) be seen as cultural preferences in the medical domain. In this paper, a prototypical argumentative pattern of Chinese medical consultations is provided. Two levels of the pattern are distinguished and discussed: a basic argumentative pattern as presented in the pragmatic-dialectical approach and its extensions due to cultural preferences as well as institutional constraints. Illustrated by an exemplary analysis on the basis of empirical data collected from Chinese consulting rooms, the impact of cultural preferences on physicians’ strategic maneuvering in argumentation is identified and recognized. It is argued that the existence and impact of cultural preferences require attention in medical argumentation. (shrink)

A comprehensive introduction to the ways in which meaning is conveyed in language. Alan Cruse covers semantic matters, but also deals with topics that are usually considered to fall under pragmatics. A major aim is to highlight the richness and subtlety of meaning phenomena, rather than to expound any particular theory. Rich in examples and exercises, Meaning in Language provides an invaluable descriptive approach to this area of linguistics for undergraduates and postgraduates alike.

A record of the words and teachings of Confucius, _The Analects_ is considered the most reliable expression of Confucian thought. However, the original meaning of Confucius's teachings have been filtered and interpreted by the commentaries of Confucianists of later ages, particularly the Neo-Confucianists of the Song dynasty, not altogether without distortion.In this monumental translation by Professor D. C. Lau, an attempt has been made to interpret the sayings as they stand. The corpus of the sayings is taken as an organic (...) whole and the final test of the interpretation rests on the internal consistency it exhibits. In other words, _The Analects_ is read in the light of _The Analects._This results in a truer understanding of Confucius' thought than the traditional interpretation and paves the way for a re-assessment of its importance in the history of Chinese thought and its relevance to the present day world.This volume also contains an introduction to the life and teachings of Confucius, and three appendices on the events in the life of Confucius, on his disciples, and on the composition of _The Analects._.

The Greeks have long been regarded as innovators across a wide range of fields in literature, culture, philosophy, politics and science. However, little attention has been paid to how they thought and felt about novelty and innovation itself, and to relating this to the forces of traditionalism and conservatism which were also present across all the various societies within ancient Greece. What inspired the Greeks to embark on their unique and enduring innovations? How did they think and feel about the (...) new? This book represents the first serious attempt to address these issues, and deals with the phenomenon across all periods and areas of classical Greek history and thought. Each chapter concentrates on a different area of culture or thought, while the book as a whole argues that much of the impulse towards innovation came from the life of the polis which provided its setting.

Abstract:Contemporary common sense holds that authenticity is an ethical ideal: that there is something bad about inauthenticity, and something good about authenticity. Here we criticize the view that authenticity is bad because it detracts from the wellbeing of the inauthentic person, and propose an alternative moral account of the badness of inauthenticity, based on the idea that inauthentic behaviour is potentially misleading.

The verb 'imagine' admits of perspectival modification: we can imagine things from above, from a distant point of view, or from the point of view of a Russian. But in such cases, there need be no person, either real or imagined, who is above or distant from what is imagined, or who has the point of view of a Russian. We call this the puzzle of perspectival displacement. This paper sets out the puzzle, shows how it does not just concern (...) language, but also states of imagining themselves, and then presents a solution. The solution draws on the idea that many reports of imagining conceal a distinctive kind of question, and such concealed questions have an extra argument place for (what we will call) an experiencer from whose perspective things are imagined. This solution has a range of advantages over other proposals in the literature, and helps to advance two debates concerning perspectival engagement with fiction. (shrink)

In Rationalities in history, the distinguished historian David d'Avray writes a new comparative history in the spirit of Max Weber. In a strikingly original reassessment of seminal Weberian ideas, d'Avray applies value rationality to the comparative history of religion and the philosophy of law. Integrating theories of rational choice, anthropological reflections on relativism, and the recent philosophy of rationality with Weber's conceptual framework, d'Avray seeks to disengage 'rationalisation' from its enduring association with Western 'modernity.' This mode of analysis is contextualised (...) through the examples of Buddhism, Imperial China, and sixteenth-century Catholicism--in the latter case building upon unpublished archival research. This ambitious synthesis of social theory and comparative history will engage social scientists and historians from advanced undergraduate level upwards, stimulating interdisciplinary discourse, and making a significant contribution to the methodology of history. D'Avray explores the potential of this new Weberian analysis further in his companion volume, Medieval religious rationalities"--Provided by publisher. (shrink)

The theme of the relationship between art and society is certainly not a central topic in the aesthetic reflection of Italian neo-idealism. Neither in Croce nor in Gentile it is ever discussed at length, and the few writings in which it is addressed are brief and polemically oriented. This essay, however, proposes to discuss the few hints present in Croce and Gentile on this subject. First, the debate on the materialistic interpretation of history will be examined, to which both Croce (...) and Gentile made important contributions at the end of the 19th century. Secondly, Croce’s own way of doing the history of literature will be discussed, showing the differences that distance him from the Desanctisian model and also from the model derived from the Hegelian Aesthetics. Croce’s way of making history of literature, indeed, aroused harsh criticism after World War II and provoked a request for a “return to De Sanctis”.Finally, but the theme will be only hinted at in the essay, a brief reference will be proposed to the opinions of Antonio Gramsci and his reading of Croce.

This is the classic study of the history and continuing philosophical values of the law of nature. D'Entrèves discerned three distinct sources that have contributed to the development of natural law: Roman law teachings, Christian beliefs regarding law, and egalitarian and revolutionary theories of the Enlightenment. Now regarded as a classic work, Natural Law has exercised considerable influence over the course of Anglo-American legal theory in the past forty years. The statements of Clarence Thomas during his 1991 Senate confirmation hearings (...) show that the law of nature still holds powerful appeal in defining judicial rules. In the new introduction, Cary J. Nederman points out both the contemporary value and the historical significance of Natural Law. He also provides the biographical as well as intellectual context for d'Entrèves immense accomplishments. This volume is essential reading for students of legal history, political theory, and philosophy. It will also be of interest to historians. "Few texts provide as concise or as cogent an introduction to natural theory as Alexander Passerin d'Entrèves' Natural Law: An Introduction to Legal Philosophy.... Transaction Publishers has performed a genuine service by bringing out a new edition of Natural Law. D'Entrèves' analysis is clear and penetrating, and will guide the student of natural law to further, fruitful study."--Mitchell Muncy, The University Bookman. (shrink)
