Philosophical Occasions, 1912-1951
[The editors] have usefully and skillfully assembled various  writings by Wittgenstein. . . . to permit a synoptic view of his several  concernsfrom comments on Frazer'sThe Golden Bough, to pieces on ethics,  sensedata, cause and effect, free will, the nature of philosophy.  There  are also some revealing letters and an informative essay by Henrik von  Wright on the writings that Wittgenstein left behind.  The book is an  excellent source and it provides a nourishing supplement to the  Investigations. --Colin McGinn inThe New Republic--This text refers to an out of print or unavailable edition of this title.
