If the body is no longer a site of otherness but of identification, then we have urgently to become reconciled with it, repair it, perfect it, turn it into an ideal object. Everyone treats their bodies the way men treat women in projective identification: they invest them as a fetish, making an autistic cult of them, subjecting them to a quasi-incestuous manipulation. And it is the body's resemblance to its model which becomes a source of eroticism and 'white' seduction -- in the sense that it effects a kind of white magic of identity, as opposed to the black magic of otherness.
This is how it is with body-building: you get into your body as you would into a suit of nerve and muscle. The body is not muscular, but muscled. It is the same with the brain and with social relations or exchanges: body-building, brainstorming, word-processing. Madonna is the ideal specimen of this, our muscled Immaculate Conception, our muscular angel who delivers us from the weaknesses of the body (pity the poor shade of Marilyn!).
The sheath of muscles is the equivalent of character armour. In the past, women merely wrapped themselves in their image and their finery -- Freud speaks of those people who live with a kind of inner mirror, in a fleshly, happy self-reference. That narcissistic ideal is past and gone; body-building has wiped it out and replaced it with a gymnastic Ego-Ideal -- cold, hard, stressed, artificial self-reference. The construction of a double, of a physical and mental identity shell. Thus, in `body simulation', where you can animate your body remotely at any moment, the phantasy of being present in more than one body becomes an operational reality. An extension of the human being. And not a metaphorical or poetic extension, as in Pessoa's heteronyms, but quite simply a technical one.
