All contents of consciousness are ineffable. Even the simplest sensation is, in its totality, indescribable. Every work of art, therefore, needs to be understood not only as something rendered, but also as a certain handling of the ineffable. In the greatest art, one is always aware of things that cannot be said, of the contradiction between expression and the presence of the inexpressible. Stylistic devices are also techniques of avoidance. The most potent elements in a work of art are, often, its silences.
Susan Sontag, ‘On Style’, in Against Interpretation and Other Essays (1966)
