which organizes the change and variety into a unity. "The reality which the supreme intelligence creates out of itself, man has first to receive, and he does in fact receive it, by way of perception, as something existing outside of him in space, and as something changing within him in time". The perfect human being, according to Schiller, would be a constant unity amongst constant change. These seemingly contradictory forces of freedom through person and time through condition, manifest themselves in humans as the form and the sense drive. These drives, and consequently humanity's experience of freedom and time, are mediated by the play drive. Sense and Form Drives Sense Drive The sense drive, in Schiller's thought, is a function of man's condition. It comes from the human being's physical existence, and the whole of their phenomenal existence stems from it. In their sensuous existence, human beings are set within the limits of time, within his condition, and becomes matter. "By matter in this context we understand nothing more than change, or reality that occupies time. Consequently this drive demands that there shall be change, that time shall have content". Therefore, sensation of the sensuous drive is time occupied by content. Form Drive The form drive, in Schiller's view, is a function of the person grounded in itself. This drive is humanity's rational nature, their "absolute existence", and its goal is to give them freedom, so they can bring harmony to the variety of things in the world. Because the form drive insists on the absolute, "It wants the real to be necessary and eternal, and the eternal and necessary to be real. In other words, it insist on truth and on the right". The sense drive and the form drive are in competition, and overpower one another in the person. In competition If the sense drive overcomes the form drive, according to Schiller, it reduces human beings to matter, but leaves them without the ability to bring this matter into unity. "As long as he merely feels, merely desires and acts upon desire, he is as yet nothing but world, if by this term we understand nothing but the formless content of time" (117). In order to not be just "world", people must exercise their form drive upon matter, and "give reality the predisposition he carries within him". When the form drive overpowers, Schiller says we experience "the greatest
