Kurt Gödel

    28 april 1906 – 14 januari 1978

    Kurt Gödel was een Oostenrijks-Amerikaanse logicus, wiskundige en filosoof die een immense impact had op het wetenschappelijke en filosofische denken in de 20e eeuw. Hij is het best bekend om zijn twee onvolledigheidsstellingen, die aantoonden dat er binnen elk voldoende krachtig formeel systeem ware uitspraken bestaan die niet uit de axioma's bewezen kunnen worden. Om deze stellingen te bewijzen, ontwikkelde Gödel een techniek die nu bekend staat als Gödelnummering, waarbij formele uitdrukkingen worden gecodeerd als natuurlijke getallen. Zijn werk aan de bewijstheorie verhelderde ook de verbanden tussen verschillende logische systemen en hij toonde aan dat de continuümhypothese niet weerlegbaar is uit de geaccepteerde axioma's van de verzamelingenleer.

      Kurt Gödel was the greatest logician of this century. This third volume of his collected works consists of previously unpublished material, both essays and lectures.

      Collected works
    • Kurt Gödel (1906 - 1978) was a preeminent logician of the twentieth century, renowned for his pivotal contributions to the completeness of logic, the incompleteness of number theory, and the consistency of the axiom of choice and the continuum hypothesis. His work also encompassed constructivity, the decision problem, and the foundations of computability theory, alongside a distinctive philosophical perspective on mathematics. Less recognized is his exploration of unique cosmological models that suggest the theoretical possibility of time travel into the past. The Collected Works serves as a significant compilation of Gödel's intellectual legacy. The first two volumes present his published works in full, both in original form and translation, while the third volume includes a selection of unpublished articles and lecture texts from Gödel's Nachlass. The final two volumes feature Gödel's correspondence on logical, philosophical, and scientific topics, with Volume IV covering A to G and Volume V covering H to Z, along with a complete inventory of his Nachlass. Each volume includes introductory notes with extensive commentary, English translations of German texts, and a comprehensive bibliography. This edition aims to be accessible to a broad audience, making it an essential resource for professionals and students in various fields, as well as anyone interested in the insights of one of the twentieth century's great minds.

      Collected works 1
    • In 1931, a young Austrian mathematician published an epoch-making paper containing one of the most revolutionary ideas in logic since Aristotle. Kurt Giidel maintained, and offered detailed proof, that in any arithmetic system, even in elementary parts of arithmetic, there are propositions which cannot be proved or disproved within the system. It is thus uncertain that the basic axioms of arithmetic will not give rise to contradictions. The repercussions of this discovery are still being felt and debated in 20th-century mathematics. The present volume reprints the first English translation of Giidel's far-reaching work. Not only does it make the argument more intelligible, but the introduction contributed by Professor R. B. Braithwaite (Cambridge University}, an excellent work of scholarship in its own right, illuminates it by paraphrasing the major part of the argument. This Dover edition thus makes widely available a superb edition of a classic work of original thought, one that will be of profound interest to mathematicians, logicians and anyone interested in the history of attempts to establish axioms that would provide a rigorous basis for all mathematics. Translated by B. Meltzer, University of Edinburgh. Preface. Introduction by R. B. Braithwaite.

      On formally undecidable propositions of Principia mathematica and related systems
    • Kurt Gödel (1906-1978) was the most outstanding logician of the twentieth century. This second volume of a comprehensive edition of Gödel's works collects the remainder of his published work, covering the period 1938-1974. (Volume I included all of his publications from 1929-1936). Each article or closely related group of articles is preceded by an introductory note that elucidates it and places it in historical context. The aim is to make the full body of Gödel's work as accessible and useful to as wide an audience as possible, without in any way sacrificing the requirements of historical and scientific accuracy.

      Collected works 2
    • Der Mathematiker Kurt Gödel hat über einen Zeitraum von 22 Jahren (1934-1955) philosophische Bemerkungen, die so genannten Maximen Philosophie (Max Phil), niedergeschrieben. Sie sind in 15 Notizbüchern in der Kurzschrift Gabelsberger überliefert. Das erste Notizheft enthält allgemeine philosophische Überlegungen, die Hefte zwei und drei bestehen aus Gödels Individualethik. Die dann folgenden Notizbücher machen deutlich, dass Gödel eine Wissenschaftsphilosophie entworfen hat, in der er seine Erörterungen zu Physik, Psychologie, Biologie, Mathematik, Sprache, Theologie und Geschichte in den Kontext einer Metaphysik stellt. Erstmals wird nun an der Kurt-Gödel-Forschungsstelle der Berlin-Brandenburgischen Akademie der Wissenschaften eine vollständige, historisch-kritische Edition von Gödels philosophischen Notizbüchern vorbereitet. Im Rahmen dieser Edition erscheint jährlich ein Band. Band 1, von Gödel mit ›Philosophie I Max 0‹ betitelt, umfasst philosophische Überlegungen Gödels sowie anderer für ihn bedeutender Autoren, die er an den Anfang seines philosophischen Gesamtprojektes gestellt hat. Die Einleitung der Herausgeberin Eva-Maria Engelen bietet einen Überblick über das Korpus.

      La casi mítica fama de Kurt Gödel entre lógicos, matemáticos y filósofos descansa en tres logros de importancia excepcional: en 1930 probó la suficiencia del cálculo lógico de primer orden; en 1931 probó que todo sistema formal que contenga un poco de aritmética es necesariamente incompleto y que es imposible probar su consistencia con sus propios medios; y en 1938-1939 probó la consistencia relativa del axioma de elección y la hipótesis del continuo respecto de los demás axiomas de la teoría de conjuntos. Pero sus artículos y trabajos, de una concisión legendaria y de una incomparable densidad intelectual, no siempre resultan fáciles de consultar, pues se encuentran desperdigados en publicaciones, actas y revistas de varios países. Estas Obras completas reúnen la totalidad de los escritos de Gödel hasta ahora publicados. Ordenados cronológicamente, cada uno de ellos va precedido de una breve introducción de Jesús Mosterín, que los sitúa en su contexto más general y a veces los resume someramente.

      Další kniha z řady základních textů evropské vzdělanosti iniciovaná Petrem Vopěnkou. A po desetiletích teprve druhá přeložená kniha zásadních textů jednoho z největších matematiků, logiků a myslitelů dvacátého století. Gödelovy věty (z roku 1931) o neúplnosti jsou i přes svojí stručnost stále vlivným textem nejen exaktních věd (zejm. matematické logiky). Přesahují do filosofie (a nejen matematiky), neboť svou podstatou stanovují omezenost i tak exaktní vědy, kterou matematika je (a ve svém důsledku třeba i nemožnost dokázat úplnou bezespornou teorii, což má důsledky i pro aritmetiku přirozených čísel). Kniha vedle těchto stěžejních textů obsahuje úvodní poznámku a bohatou předmluvu Vítězslava Švejdara, na závěr je doplněna autorovou bibliografií.
