 According to Plato, the sensible world is an imperfect copy of perfect and immutable ideas. Plato’s general view of the arts, including music, is that they are an imitation (mimesis) of objects found in the sensible world. This leads to his famous condemnation of art in Book X of his Republic. For, if our world is already a copy, then the arts provide us with copies of a copy. Thus, Plato’s metaphysics motivates his dismissive view of art’s epistemic value.
