1. Da Leibniz a Kant.--2. L'algebra della logica.

The thirteenth-century logician Lambert of Auxerre was well known for his Summa Lamberti, or simply Logica, written in the mid-1250s, which became an authoritative textbook on logic in the Western tradition. Our knowledge of medieval logic comes in great part from Lambert's Logica and three other texts: William of Sherwood's Introductiones in logicam, Peter of Spain's Tractatus, and Roger Bacon's Summulae dialectics. Of the four, Lambert's work is the best example of question-summas that proceed principally by asking and answering questions (...) on the subject matter. Thomas S. Maloney's translation of Logica, the only complete translation of this work in any language, is a milestone in the study of medieval logic. More than simply a translation, Maloney's project is a critical, comprehensive study of Lambert's logic situated in the context of his contemporaries and predecessors. As such, it offers a wealth of annotation and commentary. The lengthy introduction and extensive notes to the text explain the origin, theoretical context, and intricacies of the text and its doctrines. Maloney also addresses the disputed issues of authorship, date, and place of publication of the Summa Lamberti and makes available to the English-only audience the French, German, and Italian secondary sources--all translated--that are needed to enter the discussion. "Thomas S. Maloney fully commands the primary and secondary sources necessary to elucidate Lambert's Logica. An expert on Roger Bacon's philosophy, he demonstrates a rare proficiency in medieval Latin and scholastic logic. His references to sources from the ancient (Aristotle and Boethius) and medieval worlds are apposite, perspicuous, and useful. The volume's presentation with an appropriate introduction and commentary in the endnotes will no doubt establish it as an indispensable resource for scholars in the twenty-first century." --Alan Perreiah, University of Kentucky.

This book marks the inauguration of the Historia Logicae book series, which seeks to publish high-quality monographs, dissertations, textbooks, proceedings, and anthologies on the history of logic in either German or English. Serving as the inaugural volume in this series, the book explores the contemporary interpretation of logic across many centuries and cultures. The first section of the volume comprises a compilation of papers dedicated to ancient and medieval logic, examining prominent thinkers such as Plato, Aristotle, Seneca, Porphyry, Proclus, Boethius, (...) Buridan, and Kilwardby. The second section shifts focus towards early-modern and contemporary logics, including the works of Caramuel, Kant, Drobisch, Husserl, and Jaskowski. Topics of discussion encompass the relationship between mathematics and logic, natural deduction, intuitionism, graph theory, categorical judgments, theories of truth, modal logic, opposition relations, logic diagrams, definitions of formal logic, many-sorted logic, model theory, and paraconsistent logic.

Else Margarete Barth (1928-2015) was een Noors-Nederlandse filosoof.0Else Barth vond dat filosofie in dienst zou moeten staan van de combinatie van medemenselijkheid en helder, geïnformeerd denken en discussiëren. Barth was ervan overtuigd dat zorgvuldig redeneren en debatteren noodzakelijk is voor het verbeteren van menselijke relaties. Met logica als wapen bestreed ze vaagheid en vooroordelen. Om logica van betekenis te maken voor het praktische leven, verbond ze het met analytisch onderzoek naar ideeën die rondwaren in wetenschap en politieke cultuur. Haar bijzondere (...) belangstelling ging daarbij uit naar anti-argumentatieve en anti-parlementaire houdingen en denksystemen die, vaak ten faveure van een hoger doel, minachting voor (groepen) individuen legitimeren of zelfs aanmoedigen. Met haar pleidooi voor een 'empirische logica' leverde Barth een originele bijdrage aan de Europese wijsbegeerte, die ook voor de huidige tijd relevant is.0'Empirische logica' is een selectie uit Barths werk. De bundel bevat voorbeelden van toegepast empirisch-logisch onderzoek, naar de logische grondslagen van het Duitse idealisme bijvoorbeeld, die volgens Barth dezelfde zijn als die van de klassieke homeopathie, naar het denken van de Noorse nazi Quisling, maar ook naar de onevenredige aandacht voor 'gemiddelden' in de sociale wetenschappen, die tot stigmatisering leidt. In beschouwende stukken reflecteert de auteur onder meer op het belang van cultuur-georiënteerd logica-onderwijs en zoekt ze een verklaring voor de kloof tussen logica en politiek. Ten slotte zijn essays0opgenomen die Barth schreef over filosofen die haar inspireerden: Bertrand Russell, Evert Willem Beth en Arne Naess. (shrink)

"La Lógica pura, la idea de la Gramática pura y el problema de una filosofí­a del lenguaje en las Investigaciones Lógicas" Una de las cuestiones centrales que hasta hoy en dí­a se siguen debatiendo en torno a la recepción de las Investigaciones Lógicas, se refiere a la relación entre pensamiento y lenguaje, entre significado y expresión lingí¼í­stica, entre percepción y juicio, entre Lógica y Gramática que estableció en el debate con G. Frege y A. Marty, entre otros. El (...) autor se ocupa de las influencias -en parte directas o indirectas- que ha dejado la obra de Husserl sobre la lingí¼í­stica moderna, la filosofí­a del lenguaje del siglo XX y la filosofí­a analí­tica del lenguaje. "The pure Logic, the pure Grammar's idea and the problem of a philosophy of the language in the Logical Investigations". One of the central questions that until today is continued debating around the reception of the Logical Investigations, it refers to the relationship between thought and language. between meaning and linguistic expression, between perception and judgement, between Logic and Grammar that Husserl settled down in the debate with G. Frege and A. Marty, among others. The author is in charge of the influences -direct or indirectly- that has left the work of Husserl on the modern linguistics, the philosophy of the language of the XX century and the analytic philosophy of the language.

La filosofia non è una scienza empirica e si regge in buona misura sull’argomenta- zione (→), cioè sulla capacità di giustificare certe affermazioni, o tesi, sulla base di altre ritenute vere. Sin dall’antichità la teoria dell’argomentazione ha pertanto occupato una posizione di rilievo nella ricerca filosofica, e già a partire da Aristotele ha contribuito a definire quel settore disciplinare che oggi chiamiamo logica (dalla parola greca logos, che significa tra l’altro ‘discorso’, ‘ragionamento’). Aristotele stesso codificò la materia in maniera sistematica, (...) secondo schemi e principi che rimasero insuperati per oltre due millenni (→ sillogistica). A partire dal XIX secolo la teoria logica subì però mutamenti profondi, grazie soprattutto all’opera del matematico inglese George Boole e del filosofo tedesco Gottlob Frege, e nel XX secolo si è assistito a sviluppi straordinari che hanno portato all’applicazione della logica non solo in filosofia ma anche in altri ambiti di ricerca (dalla linguistica al diritto sino all’informatica).

This volume of the Logica Yearbook series brings together articles presented at the annual international symposium Logica 2013, Hejnice, the Czech Republic. The articles range over mathematical and philosophical logic, history and philosophy of logic, and the analysis of natural language.

Logic was understood by the Stoics in a broad sense, as the doctrine that included analysis of the forms of argumentation, rhetoric, theory of concepts and propositions, epistemology, and philosophy of language. The distinguishing characteristic of Stoic logic is the fact that it is fundamentally a logic of propositions, unlike the logic of terms belonging to the Aristotelian tradition. This study offers a new treatment of Stoic logic, in which the various topics are retraced and critically assessed.

A partire dalle ricerche storico-filosofiche di Emanuela Scribano, studiose e studiosi di fama internazionale si confrontano con i grandi temi metafisici, teologici, epistemologici, etico-politici ed estetici delpensiero moderno e contemporaneo: la teoria del soggetto, il problema mente-corpo, il punto di vista delle neuroscienze, la follia, la memoria, l'amore, il desiderio, l'inquietudine, il controllo delle passioni, il fatalismo, l'inganno divino, la creazione delle verità eterne, la profezia, gli angeli, l'ateismo virtuoso, la tolleranza, la verità rivelata, la critica dell'irrazionalismo, la musica, l'impegno (...) civile e lumanesimo cosmopolitico.
