To this day, the judgment on Schiller's aesthetics remains controversial. Opponents and admirers agree, however, that anyone interested in questions of art should be familiar with these writings. This volume includes all of Schiller's theoretical writings, edited according to the first editions or manuscripts, and explains them in their interrelation as well as in relation to their historical-philosophical foundations and social-critical motives. The commentary clarifies the internal connections of the work, its historical-philosophical foundations, and social-critical motives.
