Dieser Band enthält die vier Arbeiten Freges: Begriffsschrift, eine der arithmetischen nachgebildeten Formelsprache, 1879; Anwendungen der Begriffsschrift, 1879; Über den Briefwechsel Leibnizens und Huggens mit Papin, 1881; Über den Zweck der Begriffsschrift, 1883; Über die wissenschaftliche Berechtigung einer Begriffsschrift, 1882. Frege's research work in the field of mathematical logic is of great importance for the present-day analytic philosophy. We actually owe to Frege a great amount of basical insight and exemplary research, which set up a new standard also in other (...) fields of knowledge. As the founder of mathematical logic he severely examindes the syllogisms on which arithmetic is built up. In doing so, Frege recognized that our colloquial language is inadequate to define logic structures. His notional language corresponded to the artaivicial logical language demandes by Leibniz. Frege's achievement in the field of logic were so important, that they radiated into the domain of philosophy and influenced the development of mathematical logic decisively. (shrink)

I wish to express, first of all, my profound gratitude to Professor J. M. Bochenski, without whose assistance the present work would have not been possible. To be concise, I would like to state that his contribution to this book may be viewed at three levels: (1) that of the general spirit, (2) that of the specific ideas, theses or approaches which are expressed in its pages, (3) that of this work qua doctoral dissertation. The general spirit which has guided (...) my research coincides with that underlying Professor :Oochenski's own works, in particular his Formale Logik (Munchen 1956). Moreover, the particular occasion which suggested my investigation was a statement included in that book according to which the literature in the field still lacked a detailed work on Frege (p. 317). I wish, likewise, to express my gratitude to other professors of the University of Fribourg for their generous help. I mention especially Professors P. Wyser, M. D. Philippe, N. Luyten, and V. Kuiper. I have also benefited from Professor E. Specker's lectures at the Eidge nossische Technische Hochschule (ZUrich) and from Professor Olof Gigon's lectures at the University of Bern. From an earlier period I wish to express my gratitude to the professors of the philosophy department of the Universidad Nacional de Buenos Aires, especially the late Professor Francisco Romero. The Swiss National Library (Bern) has greatly facilitated access to bibliographical sources, and the library of the University of Munster (Westphalien) has kindly provided microfilms of Frege's Nachlap.

After presenting the ordinary and the Fregean formulations of the ancestral, I raise the question of what is their relationship, the natural candidate being that the Fregean version is an analysans intended to improve upon, and replace, the common notion of ancestral (the analysandum). Next, two types of circles that arise in connection with the Fregean ancestral are presented, and it is claimed that one of the circles makes it impossible to maintain the just described (“replacement”) interpretation. A reference is (...) made to Kerry, who was the first to point out a circularity in Frege’s ancestral. Some of Frege’s remarks are examined in order to tentatively sketch, an answer to the issue of the relationship between ordinary and Fregean ancestral; the latter, if not as an analysans replacing the common notion, can still be seen as a profound enrichment of the former.

No detailed description available for "Studies on the History of Logic".

En 1967, Ignacio Angelelli publie un ouvrage pionnier: la bibliographie fregeenne est encore assez mince quand l'etudiant du Professeur Bochenski soutient, a Fribourg en Suisse, sa dissertation doctorale. L'essentiel des ouvrages, articles et recensions du grand logicien est encore disperse et non reedite. Mais le principal interet de l'ouvrage dont nous donnons ici une premiere traduction francaise ne tient pas seulement au fait qu'il marque une date importante dans le champ des etudes fregeennes et qu'il peut constituer a sa maniere (...) un classique; son importance est directement liee a son objet et a sa methode. L'objet est clairement assigne des la premiere phrase de l'introduction. Si l'Ideographie est bien le document fondateur de la logique contemporaine, digne de prendre rang aux cotes des Analytiques d'Aristote, comment determiner plus precisement la signification et la portee de cette rupture fregeenne par rapport a la tradition philosophique? Autrement dit, il ne s'agit pour l'auteur ni de presenter un expose general de la pensee de Frege, ni de discuter de questions techniques que son oeuvre aura laisse ouvertes dans une riche posterite (Russell, Wittgenstein, Carnap, Quine...), mais bien de situer cette percee en vue de mieux la comprendre, quitte a critiquer certains de ses aspects ou de ses attendus.
