Sappho 31

“Sappho perceives desire by identifying it as a three-part structure. We may, in the traditional terminology of erotic theorizing, refer to this structure as a love triangle and we may be tempted, with post-Romantic asperity, to dismiss it as a ruse. But the ruse of the triangle is not a trivial mental maneuver. We see in it the radical constitution of desire. For, where eros is lack, its activation calls for three structural components—lover, beloved and that which comes between them. They are three points of transformation on a circuit of possible relationship, electrified by desire so that they touch not touching. Conjoined they are held apart. The third component plays a paradoxical role for it both connects and separates, marking that two are not one, irradiating the absence whose presence is demanded by eros. When the circuit-points connect, perception leaps. And something becomes visible, on the triangular path where volts are moving, that would not be visible without the three-part structure. The difference between what is and what could be is visible. The ideal is projected on a screen of the actual, in a kind of stereoscopy. The man sits like a god, the poet almost dies: two poles of response within the same desiring mind. Triangulation makes both present at once by a shift of distance, replacing erotic action with a ruse of heart and language. For in this dance the people do not move. Desire moves. Eros is a verb.” — Anne Carson, Eros the Bittersweet
