Abstract

This essay argues that Plato’s Republic includes a widely overlooked meditation on the affective dimension of political judgment. This meditation occurs in the passages on music. In music, Plato identifies the possibility of an extra-rational aesthetic activity that prepares the soul for reasoned judgment: he makes musical mimesis the precondition to logos because of its ability to actualize in the soul the very ethos required of sound judgment. Music is able to do this because it is not imagistic; music does not produce mediated representations but rather produces alterations in the condition of the soul itself. These alterations are made possible because the soul itself is structured musically. If music actualizes the conditions of the soul, so too does the soul instantiate the conditions of music. In his treatment of musical mimesis, Plato thereby makes disposition, or affect, the defining feature of sound judgment.
