…because I've fallen into some kind of Lacanian wormhole with no sign of emerging anytime soon*, here's the Aragon poem he quotes on the first page of The Four Fundamental Concepts of Psychoanalysis (Seminar XI):
Contre-chant
Vainement ton image arrive à ma rencontre
Et ne m'entre où je suis qui seulement la montre
Toi te tournant vers moi tu ne saurais trouver
Au mur de mon regard que ton ombre rêvée
Je suis ce malheureux comparable aux miroirs
Qui peuvent réfléchir mais ne peuvent pas voir
Comme eux mon æil est vide et comme eux habité
De l'absence de toi qui fait sa cécité
In vain your image comes to meet me
And does not enter me where I am who only show it
Turning towards me you can find
On the wall of my gaze only your dreamt-of shadow.
I am that wretch comparable with mirrors
That can reflect but cannot see
Like them my eye is empty and like them inhabited
By your absence which makes them blind.
