Task: Text Categorization
Input (English): This work claims that all sciences start from two types of data, one of which is identified as "ground of being" in "organon", the other of which is its "problem". The idea that both passion and intensity of emotion are unknowable to "the brute" appears in the section "Objective View of the Intellect" of this work, which also mentions the "medium of motives"; while this work's second volume consists of supplements to each of the first volume's four books. Defining one of the title concepts as a "striving, yearning, force", this work claims that daily life "is suffering" and combines consideration of the Kantian "ding an sich" with the Upanishads. For 10 points, name this magnum opus of Arthur Schopenhauer.
Output (English): Social Science
