 The “Memorandum about the New Mathematical Logic and Foundational Research” written for the Reichs- und Preußischen Minister für Wissenschaft, Erziehung und Volksbildung (Imperial and Prussian Secretary for Science, Education and National Instruction) on January 15, 1938 (Scholz 1938) shows that for Scholz this new subject went beyond symbolic or mathematical logic, but further included applications of logical analysis to foundational problems in general. According to Scholz, the new subject was prepared by Gottfried Wilhelm Leibniz (1646–1716), created by Gottlob Frege (1848–1925), and taken up by David Hilbert (1862–1943) who, adopting Bertrand Russell’s (1872–1970) elaboration of Frege’s creation, made it the subject of deep investigations aiming, e.g., “at a consistency proof for classical logic”, and with this, of classical mathematics (presupposing the logicist reduction of mathematics to logic). This new approach was, according to Scholz, directed against Kant’s opinion that “foundational questions of any kind in principle cannot be treated with mathematical methods and with mathematical means of construction and research questions”. Its task was a deepening and clarifying of foundations by combining structural investigations and the analysis of the context of application.
