Review Essay: Carnap and the Twentieth Century: Volume 1 and 2

This edition of the early diaries of Rudolf Carnap (1891–1970), which are housed in the Carnap estate at the University of Pittsburgh, was published in two volumes by Felix Meiner Verlag Hamburg in 2021 and 2022. These are also the first two volumes of the Meiner Edition Schriften aus dem Nachlass von Rudolf Carnap. The title of these two volumes is succinctly Rudolf Carnap. Tagebücher (Rudolf Carnap. Diaries), supplemented by the respective indication of the volume. Volume 1 (approx. 600 pages) comprises the diaries from 1908 to 1919, Volume 2 (approx. 900 pages) those from 1920 to 1935. With these volumes, the diaries of one of the central thinkers of the Vienna Circle and Logical Empiricism become accessible to a wider circle of researchers and interested parties. While the diaries were previously only partially accessible, they have now for the first time been released in their entirety in the form of a proper text-critical edition. The editor is Christian Damböck with the collaboration of Brigitte Arden, Roman Jordan, Brigitte Parakenings and Lois M. Rendl. Text transcriptions of the originals, which Carnap had written in shorthand, served as the basis for the edition. The transcription was done by Brigitte Parakenings and Brigitte Arden, further editing by Lois M. Rendl and Roman Jordan.
