Many commentators on Lévinas, as well as Lévinas himself, have tried to ground the subject in an address from the Other. This makes the subject fundamentally ethical, fundamentally indebted to the Other …
… what is called the subject in Lacan’s threory begins when the Other no longer addresses you. According to Lévinas, what is traumatic is the encroachment of the Other on my own psychic space. According to Lacan, what is traumatic is finding out that the Other’s desire concerns something that leaves you out of the picture. Being “touched” by the other is traumatic too, but not being touched at all is at least as bad, and in this absence of a touch can be found the core of Lacan’s theory of the subject (73).
This encounter with the Other’s desire motivates a quest for a signified and an eventual identification with that signified. The Other’s desire plays a role diferent from that played by the image in the mirror stage.
In the imaginary and symbolic identifications, a meaning or an identity is produced, and an individual is presented with a place that is already his or hers. In the encounter with the Other’s desire, I am not given any place at all, and my very being is put into question. The Other’s desire is a mirror that does not return my reflection. (74).
Because of this, the subject in Lacan’s work is not just something determined. It is also a position with respect to a determination, an affirmation or a rejection of it. The subject is some kind of negation of determination. But this negation actually originates from the resistance to signification that is found in the Other’s desire. The Other’s desire is opaque and abyssal. For this reason, it makes any determination appealing, because it is something I can always fall back on (74).
