In many places of the world, philosophy and science would not be quite the same without the thoughts developed and discussed in the Vienna Circle during the 1920ies and 1930ies. Even in this time, however, the activity of the circle was not limited to Austria but was partof the wider intellectual ferment characteristic of Central Europe in the late 19^th and early 20^th century. One of the major stages of these happenings was the young Czechoslovak Republic. In Prague the manifesto of the circle, “The Scientific World Conception”, was presented to the public in 1929. At the same place, on the Preliminary Conference of the International Congresses for the Unity of Science and the 8^th International Congress of Philosophy in 1934 Logical Empiricism was intensively discussed by members, fellow-travelers as well as critics of the circle. Czechoslovakia was a visiting, working and living place for Bernard Bolzano, Ernst Mach, Albert Einstein, Rudolf Carnap, Philipp Frank, and others. The conference intends to map the remarkable interconnections of the Czechoslovak environment and the work of the Vienna Circle on the philosophical, scientific and artistic level. Possible topics include (but are not limited to):

• Precursors of the Vienna Circle (Bernard Bolzano, Ernst Mach, etc.) and the Czechoslovak region

• Members and friends of the Vienna Circle in Prague (Rudolf Carnap, Albert Einstein, Philipp Frank, W.V.O Quine, etc.)

• Tomáš G. Masaryk’s legacy and scientific philosophy

• Major events in Czechoslovakia linked to the development of logical empiricism (The First Conference for the Epistemology of the Exact Sciences – 1929, The Preliminary Conference of the International Congresses for the Unity of Science -1934, The Eighth International Congress of Philosophy – 1934, etc.)

• The European scientific rectangle Vienna-Berlin-Warsaw-Prague

• ISOTYPE and Czechoslovak art and education (Augustin Tschinkel, Ladislav Sutnar, Vladimír Konvička etc.)

• Parallels and controversies between the Prague Linguistic Circle and the Vienna Circle

• Czechoslovak appraisal and critique of Logical Empiricism before and during the Second World War

• Logical Empiricism in the communist period in Czechoslovakia

• Logical Empiricism in current Czech/Slovak analytical philosophy
