This compelling reevaluation of the relationship between logic and knowledge affirms the key role that the notion of judgement must play in such a review. The commentary repatriates the concept of judgement in the discussion, banished in recent times by the logical positivism of Wittgenstein, Hilbert and Schlick, and the Platonism of Bolzano. The volume commences with the insights of Swedish philosopher Per Martin-Löf, the father of constructive type theory, for whom logic is a demonstrative science in which judgement is (...) a settled feature of the landscape. His paper opens the first of four sections that examine, in turn, historical philosophical assessments of judgement and reason; their place in early modern philosophy; the notion of judgement and logical theory in Wolff, Kant and Neo-Kantians like Windelband; their development in the Husserlian phenomenological paradigm; and the work of Bolzano, Russell and Frege. The papers, whose authors include Per Martin-Löf, Göran Sundholm, Michael Della Rocca and Robin Rollinger, represent a finely judged editorial selection highlighting work on philosophers exercised by the question of whether or not an epistemic notion of judgement has a role to play in logic. The volume will be of profound interest to students and academicians for its application of historical developments in philosophy to the solution of vexatious contemporary issues in the foundation of logic. ​.

Dans l’essai Objets intentionnels de 1894, Husserl développe en réaction à Twardowski une théorie originale de l’assomption comme solution au problème des représentations sans objet. Après avoir examiné le détail de cette théorie et en avoir soulevé les difficultés, je montre dans cet article que la solution proposée par cette théorie doit être abordée de manière indépendante de celle qui sera développée plus tard dans les Recherches logiques et j’expose dans quelle mesure elle est ancrée dans la psychologie descriptive brentanienne (...) tout en mettant à profit certains outils de la logique de Bolzano. Enfin, j’indique que Husserl continuera à développer cette théorie après les Recherches logiques, confirmant ainsi qu’elle occupe une place de choix dans la théorie phénoménologique du jugement.In his essay Intentional Objects of 1894, Husserl develops in response to Twardowski an original theory of assumptions as a solution to the problem of objectless presentations. First, I analyze in this paper the main points of his theory and point out some of the difficulties it raises. I then suggest that the solution presented in this theory must be addressed independently of the one developed by Husserl later in the Logical Investigations and try to show in which extent his theory of assumptions is rooted in the brentanian descriptive psychology, although it makes good use of some logical tools from Bolzano’s Wissenschaftslehre. Since Husserl continues to work on this theory even after the Logical Investigations, it confirms the important place one should give to the theory of assumptions it the phenomenological theory of judgment.

The twelve original studies collected in this volume examine different aspects of Edmund Husserl's Logical Investigations. They are authored by scholars and specialists internationally recognized for their expertise in the fields of phenomenology, logic, history of philosophy and philosophy of mind. They approach Husserl's groundwork from different angles and perspectives and shed new light on a number of issues such as meaning, intentionality, ontology, logic, etc. They also explore questions such as the place of the Logical Investigations within the whole (...) of Husserl's work, its sources in 19th century philosophy and in particular in the philosophical work of Franz Brentano and Bernard Bolzano, its reception amongst the so-called members of the Munich Circle and its influence on contemporary philosophy. In short, this volume constitutes a "companion" to Husserl's Logical Investigations. (shrink)
