Jusqu'à maintenant, il semble qu'on n'ait pas établi de lien entre le rejet par Bolzano de la notation quantificationnelle des propositions universelles de la logique traditionnelle et l'articulation inédite de sa notion de validité universelle. C'est ce que je veux faire ici. En particulier, dans la mesure où l'analyticité est un cas spécial de la validité universelle, j'ai l'intention de défendre l'idée qui veut que la notion bolzanienne d'analyticité cherche à résoudre des problèmes qui sont intrinsèquement liés à la théorie traditionnelle de la quantification universelle tels qu'ils surviennent, notamment avec le traitement kantien de l'analyticité. It seems that the connection between Bolzano's rejection of the traditional quantificational notation for universal propositions and the articulation of his notion of universal validity has remained, until today, perfectly unnoticed. In this paper, I will show that there is such a connection. Particularly, since analyticity is a special case of universal validity, my intention is to show that the problems to which Bolzano's perfectly original account of analyticity seeks to find an answer are intrinsically related to the traditional conception of universal quantification as it arises in the context of Kant's treatment of analyticity

In the wake of Kant, logicians seemed to have adhered to the idea that what is distinctive of logic is its “formality”. In the paper, I discuss the distinction Kant draws between formality and generality of logic and argue that he ultimately conflates the two notions. I argue further that Kant's views on the formality of logic rest on a series of non trivial assumptions concerning the nature of cognition. I document the way in which these assumptions were received in his successors. In the second part of the paper I focus on Bolzano's criticism of the Kantian position and his redefinition of the notion of form. I argue that while what contemporary, post-Tarskian philosophers generally understand as the formality of logic ought to be traced back to Bolzano there are also important differences between the two positions.

Bolzano fut le premier philosophe à établir une distinction explicite entre les procédés déductifs qui nous permettent de parvenir à la certitude d’une vérité et ceux qui fournissent son fondement objectif. La conception que Bolzano se fait du rapport entre ce que nous appelons ici, d’une part, « conséquence subjective », à savoir la relation de raison à conséquence épistémique et, d’autre part, la « conséquence objective », c’est-à-dire la fondation, suggère toutefois que Bolzano défendait une conception « explicativiste » de la preuve : les preuves par excellence sont celles qui reflètent l’ordre de la fondation objective. Dans cet article nous faisons état des problèmes liés à une telle conception et argumentons en faveur d’une démarcation plus stricte entre la préoccupation ontologique et la préoccupation épistémologique dans l’élaboration d’une théorie de la preuve.Bolzano was the first to establish an explicit distinction between the deductive methods that allow us to recognise the certainty of a given truth and those that provide its objective ground. His conception of the relation between what we, in this paper, call “subjective consequence”, i.e. the relation from epistemic reason to consequence and “objective consequence”, i.e. grounding however suggests that Bolzano advocated an “explicativist” conception of proof : proofs par excellence are those that reflect the objective order of grounding. In this paper, we expose the problems involved by such a conception and argue in favour of a more rigorous demarcation between the ontological and the epistemological concern in the elaboration of a theory of proof.

Dans La crise des sciences européennes Husserl entreprenait de démontrer les causes de l’échec de ce qu’il appelle d’une manière générale «l’objectivisme physicaliste» de manière à établir les avantages de la méthode phénoménologique. L’expédient qu’il choisissait à cet effet consistait en une «méditation historique et critique». Pour le profane, le produit est plus ou moins convaincant: les réflexions de Husserl demeurent pour la plupart superficielles et n’ont d’historiques à vrai dire que le fait que les philosophes dont il est question appartiennent au passé. Avec Husserl et la philosophie analytique, Richard Cobb-Stevens reprend tacitement le programme de la Krisis, mais cette fois selon la perspective d’un interprète ayant une solide connaissance tant de l’œuvre de Husserl que des problématiques et des textes appartenant à la plus récente incarnation du «positivisme»: la tradition logico-analytique. Il s’agit de la traduction de Husserl and Analytical Philosophy publié chez Kluwer en 1990.

L'une des doctrines traditionnelles qui a le plus stimulé les deux premières générations de philosophes analytiques est l'idée kantienne d'une distinction entre jugements analytiques et synthétiques. À cet égard, l'ardeur philosophique fut d'ailleurs si grande que dès le début des années cinquante on était parvenu au constat qu'elle ne survivrait pas au XXe siècle. Ce fut d'abord la notion de jugement synthétique a priori qui tomba sous la critique que lui adressaient les membres du Cercle de Vienne. Quelques années plus tard, Quine s'attaquait à la dichotomie entre jugements analytiques et synthétiques avec le résultat que la distinction elle-même se vit chassée du champ de la sémantique et de l'épistémologie. Or, contre toute apparence, la question ne semble pas être définitivement réglée. L'objectif premier de Jocelyn Benoist dans son livre L'a priori conceptuel consiste à explorer la possibilité de réhabiliter une certaine notion de synthèse a priori. Cette notion proviendrait d'une lecture bolzanienne de la conception husserlienne de l'a priori matériel, c'est-à-dire d'une lecture faite à la lumière de la théorie des «propositions conceptuelles pures» que présente Bernard Bolzano dans sa Théorie de la science.

This paper is aimed at understanding one central aspect of Bolzano's views on deductive knowledge: what it means for a proposition and for a term to be known a priori. I argue that, for Bolzano, a priori knowledge is knowledge by virtue of meaning and that Bolzano has substantial views about meaning and what it is to know the latter. In particular, Bolzano believes that meaning is determined by implicit definition, i.e. the fundamental propositions in a deductive system. I go into some detail in presenting and discussing Bolzano's views on grounding, a priori knowledge and implicit definition. I explain why other aspects of Bolzano's theory and, in particular, his peculiar understanding of analyticity and the related notion of Ableitbarkeit might, as it has invariably in the past, mislead one to believe that Bolzano lacks a significant account oï a priori knowledge. Throughout the paper, I point out to the ways in which, in this respect, Bolzano's antagonistic relationship to Kant directly shaped his own views

This book offers new perspectives on the history of analytical philosophy, surveying recent scholarship on the philosophical study of mind, language, logic and reality over the course of the last 200 years. Each chapter contributes to a broader engagement with a wider range of figures, topics and disciplines outside of philosophy than has been traditionally associated with the history of analytical philosophy. The book acquaints readers with new aspects of analytical philosophy’s revolutionary past while engaging in a much needed methodological reflection. It questions the meaning associated with talk of 'analytic' philosophy and offers new perspective on its development. It offers original studies on a range of topics – including in the philosophy of language and mind, logic, metaphysics and the philosophy of mathematics – and figures whose relevance, when they is not already established as in the case of Russell, Moore and Wittgenstein, are just now beginning to become the topic of mainstream literature: Franz Brentano, William James, Susan Langer as well as the German and British logicians of the nineteenth century.

Les études colligées dans le présent ouvrage ont pour objet les Recherches logiques de Edmund Husserl. La plupart de ces études sont issues du colloque "Les Recherches logiques d'Edmund Husserl, origines et postérité de la phénoménologie (1900/1)" qui a eu lieu à Montréal au mois de mai 2001. Le prétexte à cet événement était de marquer le centenaire de la publication de l'ouvrage séminal de la phénoménologie par une réflexion sur sa signification actuelle, ses origines et sa postérité. L'ouvrage contient douze études qui examinent divers aspects des Recherches logiques de Husserl.

In the course of the last few decades, Bolzano has emerged as an important player in accounts of the history of philosophy. This should be no surprise. Few authors stand at a more central junction in the development of modern thought. Bolzano's contributions to logic and the theory of knowledge alone straddle three of the most important philosophical traditions of the 19th and 20th centuries: the Kantian school, the early phenomenological movement and what has come to be known as analytical philosophy. This paper identifies three Bolzanian theoretical innovations that warrant his inclusion in the analytical tradition: the commitment to ‘logical realism’, the adoption of a substitutional procedure for the purpose of defining logical properties and a new theory of a priori cognition that presents itself as an alternative to Kant's. All three innovations concur to deliver what counts as the most important development of logic and its philosophy between Aristotle and Frege. In the final part of the paper, I defend Bolzano against a common objection and explain that these theoretical innovations are also supported by views on syntax, which though marginal are both workable and philosophically interesting.

Bolzano was the first to establish an explicit distinction between the deductive methods that allow us to recognise the certainty of a given truth and those that provide its objective ground. His conception of the relation between what we, in this paper, call "subjective consequence", i.e., the relation from epistemic reason to consequence and "objective consequence", i.e., grounding however allows for an interpretation according to which Bolzano advocates an "explicativist" conception of proof: proofs par excellence are those that reflect the objective order of grounding. In this paper, we expose the problems involved by such a conception and argue in favour of a more rigorous demarcation between the ontological and the epistemological concern in the elaboration of a theory of demonstration.
