Abstract

Research and publications on Wittgenstein and on the Vienna Circle of Logical Empiricism have been steadily increasing in recent decades. Nevertheless, detailed comparisons between the single famous philosopher and the influential circle around Moritz Schlick are less often undertaken. To be sure, the reception and impact of Wittgenstein’s Tractatus (TLP) on the Vienna Circle is a familiar topic as are the conversations Wittgenstein had with Schlick and Waismann. This introductory essay suggests that a broader focus be adopted. The first part provides an overview of the multi-faceted Vienna Circle based on recent historiography and primary sources; the second part offers a new perspective on the complex relations between Wittgenstein and the Vienna Circle. To this end, a case study of a central relevant document is provided, namely of Rose Rand’s “Development of the Theses of the ‘Vienna Circle’” (1932/33). A close reading of this unique source sheds new light on the central philosophical triangle of Wittgenstein-Schlick-Waismann and opens up new avenues for future analyses. These considerations are offered to provide a thematic frame for the papers contained in this volume documenting the international conference on “Wittgenstein and the Vienna Circle”, held in Vienna, June 2021 to mark the centenary of the publication of Wittgenstein’s Logisch-philosophische Abhandlung (1921) / Tractatus Logico-Philosophicus (1922).
