Friedrich Schiller developed the concept of the play drive, a conjoining through contradiction of man's experience of the infinite and finite, freedom and time, sense and reason, life and form. The object of the play drive is the living form, and in contemplation of the beautiful it allows man to become most human. To understand how he comes to this conclusion, it is important to trace the origins of life and form, as a function of the two drives that the play drive mediates: the form drive and the sense drive. These two drives are themselves functions of man's person and condition, which Schiller initially describes in terms of the absolute and time.
