Werturteilsstreit

The value judgment controversy (German:"Werturteilsstreit") is a "Methodenstreit", a quarrel in German sociology and economics, around the question whether the social sciences are a normative obligatory statement in politics and its measures applied in political actions, and whether their measures can be justified scientifically.
The quarrel took place in the years before World War I, between the members of the "Verein für Socialpolitik". Main opponents were Max Weber, Werner Sombart and Gustav Schmoller.
The "Zweite Werturteilsstreit" is the debate between the supporter of the "Kritische Theorie" and the "Kritischer Rationalismus" during the 1960s — better known as "Positivismusstreit".
