H.-J. Glock has made important contributions to discussions of rationality, reasons, and rules. This chapter addresses four conceptions of rationality that Glock identifies. One of these conceptions of rationality is that rationality consists in responsiveness to reasons. This chapter goes on to consider the idea that reasons became prominent in normative ethics because of their usefulness in articulating moral pluralism. The final section of the chapter connects reasons and rules and contends that both are ineliminable.

In his paper on ‘Frege's Theory of Sense and Reference’ Saul Kripke remarks: “Like the present account, Künne stresses that for Frege times, persons, etc. can be part of the expression of the thought. However, his reading is certainly not mine in significant respects . . .”. On both counts, he is right. As regards the differences between our readings, in some respects I shall confess to having made a mistake, in several others I shall remain stubbornly unmoved. Thus I (...) shall insist on the need for distinguishing Fregean sense from linguistic (lexico-grammatical) meaning, I shall resist Kripke's function-theoretic account of ‘hybrid’ thought-expressions, and I shall deplore his transformation of Gottlob Frege into Gottrand Fressell. As regards this transformation, I shall argue that some of the main points Kripke wants to drive home do not depend on it. (shrink)

This article presents an historical and conceptual overview on different approaches to logical abstraction. Two main trends concerning abstraction in the history of logic are highlighted, starting from the logical notions of concept and function. This analysis strictly relates to the philosophical discussion on the nature of abstract objects. I develop this issue further with respect to the procedure of abstraction involved by (typed) λ-systems, focusing on the crucial change about meaning and predicability. In particular, the analysis of the nature (...) of logical types in the context of Constructive Type Theory allows elucidation of the role of the previously introduced notions. Finally, the connection to the analysis of abstraction in computer science is drawn, and the methodological contribution provided by the notion of information is considered, showing its conceptual and technical relevance. Future research shall focus on the notion of information in distributed systems, analysing the paradigm of information hiding in dependent type theories. (shrink)

Ce numéro thématique de la revue Philosophiques est consacré aux Conférences Hugues Leblanc qui ont eu lieu du 1er au 3 avril 2010 au Département de philosophie de l'Université du Québec à Montréal. À cette occasion, le conférencier invité était Kevin Mulligan, titulaire de la chaire de philosophie analytique au Département de philosophie de l'Université de Genève, qui a prononcé trois conférences sous le titre " Wittgenstein vs ses prédécesseurs austro-allemands ", publiées dans ce numéro. Mulligan y développe un de (...) ses thèmes historiques de prédilection, à savoir la dette de Wittgenstein, dans ses travaux sur l'esprit et le langage, à l'endroit de ses prédécesseurs austro-allemands. Comme le veut la formule des conférences Hugues Leblanc, nous avons réuni quelques collègues afin de discuter de quelques-uns des aspects des travaux du conférencier invité et nous avons ajouté, pour compléter ce numéro de Philosophiques, quelques articles originaux portant également sur d'autres aspects des travaux de Mulligan. On peut regrouper l'ensemble de ces contributions sous quatre des grands thèmes exploités par Mulligan en philosophie : le domaine de l'ontologie (incluant les relations, les tropes, les états de choses et les vérifacteurs), le domaine de la philosophie de l'esprit, celui des émotions et des valeurs, et enfin le thème historique de la philosophie austro-allemande, de Bolzano à Wittgenstein en passant par M. Scheler et la phénoménologie de Munich. Faute de pouvoir rendre compte dans cette préface de l'ensemble de ces riches contributions à ce numéro de Philosophiques, je me contenterai de renvoyer le lecteur aux résumés, préparés par les auteurs de ces contributions, qui précèdent chacun des articles.

The paper offers an account of the structure of information provided by models that relevantly deviate from reality. It is argued that accounts of scientific modeling according to which a model’s epistemic and pragmatic relevance stems from the alleged fact that models give access to possibilities fail. First, it seems that there are models that do not give access to possibilities, for what they describe is impossible. Secondly, it appears that having access to a possibility is epistemically and pragmatically idle. (...) Based on these observations, an alternative is developed. (shrink)

According to Frege, expressions shift their reference when they occur in indirect contexts: in “Anna believes that Plato is wise” the expression “Plato” no longer refers to Plato but to what is ordinarily its sense. Many philosophers, including Carnap, Davidson, Burge, Parsons, Kripke and Künne, believe that on Frege's view the iteration of indirect context creating operators gives rise to an infinite hierarchy of senses. While the former two take this to be problematic, the latter four welcome the hierarchy with (...) open arms. In this paper I argue that the hierarchy should be avoided and that it can be avoided.

Among philosophers of mind, it is common to assume that at least some mental properties are functional in nature, and that functional properties are second-order properties. In the functionalist literature, the notion of being a second-order property is cashed out in three different ways: (i) in terms of semantic features of characterizations or definitions of properties, (ii) in terms of syntactic features of second-order quantification, and (iii) in terms of a metaphysical criterion, according to which properties are second order if (...) they are properties of first-order properties. It is shown that in the context of functionalism reference to these interpretations is misguided, and it is suggested that the notion of an ordering of properties in this context is best understood as being tied to dependence-relations.

The role of possible worlds in philosophy is hard to overestimate. Nevertheless, their nature and existence is very controversial. This is particularly serious, since their standard applications depend on there being sufficiently many of them. The paper develops an account of possible worlds on which it is particularly easy to believe in their existence: an account of possible worlds as pleonastic entities. Pleonastic entities are entities whose existence can be validly inferred from statements that neither refer to nor quantify over (...) them as a matter of conceptual necessity. Definitions are proposed that ensure that this is the case for possible worlds. (shrink)

This explorative article is organized around a set of questions concerning the concept of a function. First, a summary of certain general facts about functions that are a common coin in contemporary logic is given. Then Frege's attempt at clarifying the nature of functions in his famous paper Function and Concept and in his Grundgesetze is discussed along with some questions which Freges' approach gave rise to in the literature. Finally, some characteristic uses of functional notions to be found in (...) the work of Bernard Bolzano and in Edmund Husserl's early work are presented and elucidated. (shrink)

Des philosophes de la logique comme Prior et Mulligan considèrent le connecteur de vérité ‘Il est vrai que ’ comme étant plus fondamental que le prédicat de vérité ‘ est vrai’. Des philosophes comme Bolzano et Horwich ont adopté l’ordre inverse de priorités et je me suis rallié à eux dans Conceptions of Truth. Je continue à penser que le prédicat « porte la culotte » et vais tenter de désamorcer les arguments contre cette conception, mais je vais aussi rejeter (...) un de mes arguments antérieurs en faveur de celle-ci.Logical Philosophers like Prior and Mulligan regard the truth connective ‘It is true that ’ as more basic than the truth predicate ‘ is true’. Philosophers like Bolzano and Horwich have adopted the opposite priority setting, and in Conceptions of Truth I joined them. I still think that the predicate ‘wears the trousers’, and I shall try to defuse the arguments against this view, but I shall also reject one of my earlier arguments for it. (shrink)

Nelson Goodman's proposal for a reconception of meaning consists in replacing the absolute notion ofsameness of meaning by that oflikeness of meaning (with respect to pertinent contexts). According to this view, synonymy is a matter of degree (of interreplaceability) with identity of expression as a limiting case. Goodman's demonstration that no two expressions are exactly alike in meaning is shown to be unsuccessful. Although it does not make use of quotational contexts for the test of interreplaceability, it is tantamount to (...) their acceptance. Goodman rejects quotational contexts; I argue that they should be accepted. This move offers two advantages.Firstly, and mainly, it allows interlinguistic comparison of meaning, something that has not been deemed possible in the received version of Goodman's account.Secondly, it restores the full scale of likeness of meaning damaged by the renunciation of those contexts that guarantee difference in meaning for diverse expressions.

Magda B. Arnold's theory of emotion is examined from three historical viewpoints. First, I look backward from Arnold to precursors of her theory of emotion in 19th century introspectionist psychology and in classical evolutionary psychology. I try to show that Arnold can be regarded as belonging intellectually to the cognitive tradition of emotion theorising that originated in Brentano and his students, and that she was also significantly influenced by McDougall's evolutionary view of emotion. Second, I look forward from Arnold to (...) the influence she had on Richard S. Lazarus, the theorist who deserves the most credit for popularising the appraisal approach to emotion. Here, I try to document that Lazarus’ theory of the stress emotions preserved most assumptions of Arnold's theory. Finally, I look back at Arnold from today's perspective and address points of success of the appraisal paradigm in emotion psychology, as well as some remaining problems. (shrink)
