There is one place in which one's privacy, intimacy, integrity and inviolability are guaranteed - one's body, a unique temple and a familiar territory of sensa and personal history.

Hence the all-pervasive, long-lasting, and, frequently, irreversible effects and outcomes of torture.

The CIA, in its "Human Resource Exploitation Training Manual - 1983" (reprinted in the April 1997 issue of Harper's Magazine), summed up the theory of coercion thus:

"The purpose of all coercive techniques is to induce psychological regression in the subject by bringing a superior outside force to bear on his will to resist. Regression is basically a loss of autonomy, a reversion to an earlier behavioral level. As the subject regresses, his learned personality traits fall away in reverse chronological order. He begins to lose the capacity to carry out the highest creative activities, to deal with complex situations, or to cope with stressful interpersonal relationships or repeated frustrations."

Inevitably, in the aftermath of torture, its victims feel helpless and powerless. This loss of control over one's life and body is manifested physically in impotence, attention deficits, and insomnia. This is often exacerbated by the disbelief many torture victims encounter, especially if they are unable to produce scars, or other "objective" proof of their ordeal. Language cannot communicate such an intensely private experience as pain
