 Because romantic art’s content is inward freedom, sculpture is no longer adequate, as it is bound to the representation of three-dimensional figures. Painting, however, abandons the third dimension, and is further able to express interiority through the use of color. But in subjective inwardness the spatial dimension is altogether absent. Its only appreciable dimension is that of the temporal unfolding of our mental life, characterized by the rapid succession of states that replace one another in our consciousness. Music is the art that is best suited to the expression of this inward dimension, as it abandons spatial extension entirely, and develops solely through time. Music is thus the art form that is best suited to romantic art.
