Philosophical Papers

The Voices of Wittgenstein brings for the first time, in both the original German and in English translation, over one hundred short essays in philosophical logic and the philosophy of mind. This text is of key historical importance to understanding Wittgenstein's philosophical thought and development in the 1930's. Transcribed from the papers of Friedrich Waismann and dating from 1932 to 1935, the majority are highly important dictations by Wittgenstein to Waismann. It also includes texts of redrafted material by Waismann, closely based on these dictations.

The Voices of Wittgenstein

Ludwig Wittgenstein

Gordon P. Baker

This work brings in both the original German and English translation of over one hundred short essays in philosophical logic and the philosophy of mind of historical importance to understanding Wittgenstein's philosophical thought and development in the 1930's. Transcribed from the papers of Friedrich Waismann and dating from 1932-35, the majority are highly important dictations by Wittgenstein to Waismann, but also includes texts of redrafted material by Waismann closely based on the dictations. Many of these texts become the ultimate sources of material on philosophy of language that constitutes the bulk of Waismann's book Logic, Sprache, Philosophy (The Principles of Linguistic Philosophy). The transcriptions throw light on the development of Wittgenstein's thought in this period and some of the topics are not covered in any of the existing publications of his writings, in particular his detailed attention to causal theories of meaning. They also contain texts covering psychological concepts such as expecting, intending and experience; these have no counterparts in Waismann's publications.
