 In 1952 Scholz published together with Hans Hermes the section “Mathematische Logik” in the Enzyklopädie der Mathematischen Wissenschaften (Hermes and Scholz 1952), a comprehensive survey of classical, bivalent and decidable logic. They focused on sentential logic based on the notion of universal validity (Allgemeingültigkeit). They argued for the priority of semantical over syntactical considerations.
