Moritz Schlick (1882–1936)—the integrating figure of the Vienna Circle—is an inspiring thinker who philosophizes in the immediate vicinity of contemporary physics in particular and other empirical sciences including psychology as well as ethics. In the context of interpreting Einstein’s (general) theory of relativity he wrote his „Space and time in contemporary physics, an introduction to the theory of relativity and gravitation“ [“Raum und Zeit in der gegenwärtigen Physik: zur Einführung in das Verständnis der Relativitäts- und Gravitationstheorie”]—first published in 1917. Schlick developed his conception of space-time coincidences of events. For the second edition he added the new chapter “X. Relations to Philosophy” using coincidences methodologically to connect terms which belong to different spaces of meaning. Starting in 1934—in the context of the debate on protocol sentences mainly with Otto Neurath and Rudolf Carnap—he offered his approach of Konstatierungen[1] to answer the question: “What is to be regarded as our fundament of knowledge?” I will shortly discuss Schlick’s term coincidence, move on to Konstatierungen and show some interrelations between them. I will argue for the methodological creativity in Schlick’s science-oriented philosophizing by explicating the inner structure of Konstatierungen within my 2-dimensional language of analysis. Finally, I will compare Schlick’s Konstatierungen with Kant’s synthetic a priori judgments and Frege’s thoughts as interrelated cases of two-dimensionally structured intermediate cases.
