 [W]e have before us a purely methodological classification of the empirical sciences that is grounded upon sound logical concepts. The principle of classification is the formal property of the theoretical or cognitive objectives of the science in question. One kind of science is an inquiry into general laws. The other kind of science is an inquiry into specific historical facts. In the language of formal logic, the objective of the first kind of science is the general, apodictic judgment; the objective of the other kind of science is the singular, assertoric proposition. (Windelband 1894: 291)
