  Schiller’s “Kallias” letters, written to his friend Gottfried Körner in January and February of 1793, were not historically influential, since they were not published for another half-century, but are fascinating reading today. In them Schiller argues that Kant’s “subjectivist” conception of free play in aesthetic response has to be complemented with an “objectivist” conception of beauty as the appearance of freedom or self-determination in the object: a beautiful form is one that appears to us to be determined not by any forces outside of it but only by itself. For that reason “A form is beautiful, one might say, if it demands no explanation, or if it explains itself without a concept” (“Kallias” letter of 18 February 1793, p. 155).  Although Schiller does not mention his name, his theory could also be interpreted as an attempt to refine Moritz’s conception of beauty as that which is complete within itself. Had Kant known these letters, however, he could have replied that Schiller’s notions of appearing to be self- rather than other-determined and demanding no explanation are still subjective, that is, they characterize how we respond to beautiful objects rather than designating any properties that could be attributed to objects independently of our response to them.
