Bøker av Ludwig Wittgenstein

This analyzes in depth such topics logical compulsion and mathematical conviction; calculation as experiment; mathematical surprise, discovery, and invention; Russell's logic, Godel's theorem, cantor's diagonal procedure, Dedekind's cuts; the nature of proof and contradiction; and the role of mathematical propositions in the forming of concepts.

This is a facsimile reproduction of an early version of Wittgenstein's Tractatus Logico-Philosophicus, discovered in 1965. The text is edited to indicate all relevant deviations from the final version.

This bilingual volume - English and German on facing pages - brings together the writings Wittgenstein composed during his stay in Dublin between October 1948 and March 1949, one of his most fruitful periods. These writings helped form Part 2 of his "Philosophical Investigations".

Peter Winch's translation of Wittgenstein's remarks on culture and value presents all entries chronologically, with the German text alongside the English and a subject index for reference. "It was Wittgenstein's habit to record his thoughts in sequences of more or less closely related 'remarks' which he kept in notebooks throughout his life. The editor of this collection has gone through these notebooks in order to select those 'remarks' which deal with Wittgenstein's views abou the less technical issues in his philosophy. So here we have Wittgenstein's thoughts about religion, music, architecture, the nature of philosophy, the spirit of our times, genius, being Jewish, and so on. The work is a masterpiece by a mastermind."-Leonard Linsky

Zettel is a collection of fragments which Wittgenstein cut from various of his typescripts and preserved for future use. More than half of the fragments were written in the years 1946–1948, after the completion of Part I and before the composition of Part II of the Philosophical Investigations. This collection may therefore be regarded as a companion volume to the Investigations, adding to both the scope and the Unity of Wittgenstein′s chef d′oeuvre. The fragments were kept in a box and were not strictly ordered. Many have marks showing changes and improvements made after they were cut from the typescripts; some have remarks added in handwriting. Editing the collection for publication was thus a task of considerable difficulty. Since Zettel was first published, further research has been carried out on the fragments and minute comparisons have been made with their typescript and manuscript sources, revealing certain inaccuracies and misinterpretations in the first editing of the work. The second edition corrects these shortcomings and includes new explanatory footnotes; a detailed index, compiled by Stephen Amdur, has also been added.
