A pair of excellent books about the Vienna Circle of philosophers have recently appeared: Exact Thinking in Demented Times: The Vienna Circle and the Epic Quest for the Foundations of Science by Karl Sigmund (2017) and The Murder of Professor Schlick: The Rise and Fall of the Vienna Circle by David Edmonds (2020).
As an undergraduate, I took several philosophy courses and was especially taken with Wittgenstein. In the spring of 1972, a multi-talented astronomy graduate student, Joseph Timko, also keenly interested in philosophy, and I wrote and performed a short play about the murder of Moritz Schlick, The Best Picture. Performing the role of Schlick, I was murdered each evening. The play was performed again in 1975 in New York and on a few other occasions.
Working in Vienna during 1979-1982 at the International Institute for Applied Systems Analysis, I was eager to learn more about the Vienna Circle. Much curiosity then pertained to Vienna 1900 but little to Vienna between the wars. I attended the Kirchberg Wittgenstein symposium in 1981, where one felt stirrings of the revival now mature in the Sigmund and Edmonds books. In honor of the Schlick revival, find posted a slightly revised 1980 version of The Best Picture, a melodrama in which Ludwig Wittgenstein, Private Investigator, made his stage debut in solving the Case of the Posthmous Positivist.
