"The most important book edition of the century" is how Sir Karl Popper praised the publication of the writings of Ludwig Wittgenstein in the Wiener Ausgabe. With all its original interconnections, criss-crossing and variants, Wittgensteins meandering flow of thought is revealed here in full for the first time: a network-like tapestry of thought in which readers can explore their own paths of discovery. These softcover Study Texts are published in a handy format of 165 x 242 mm, yet correspond page for page to the complete edition. They are thus fully compatible with the Wiener Ausgabe and its Apparatus, as well as the forthcoming Commentary volumes, and will be developed in line with the expansion of the Wiener Ausgabe. In short, a complete and faithful edition of the writings of Wittgenstein at a reasonable price.
