This work represents Wittgenstein's distillation of two decades of intense work on the philosophies of mind, language and meaning. This edition is published on the 50th anniversary of Wittgenstein's death, and incorporates final revisions by Anscombe to her original English translation.
It is a book that can be read in three ways. Sometimes I will read it from cover to cover. Other times one can read just a group of sections on a specific topic, say the rules for use being the meaning of a word. Lastly I can light my pipe, sit by the fire and read a few sections at random - it always generates new ideas. In this it has an unexpected affinity with a volume of poems.
Wittgenstein is not everybody's cup of tea, but he is mine, and if one is open-minded, this work, along with the Tractatus and the Remarks on Mathematics, has something to offer to all.
By the way, although LibraryThing classifies this work as German philodophy, Wittgenstein, like several Logical Positivists, was an Austrian.
