The body image - here specifically proprioception - emerges as the lifeline of identity, and Sacks invokes a metaphor of property and possession to conceptualize it: \r\n\r\n>One may be said to 'own' or 'possess' one's body - at least its limbs and movable parts - by virtue of a constant flow of incoming information, arising ceaselessly, throughout life, from the muscles, joints and tendons. One has oneself, one is oneself, because the body knows itself, confirms itself, at all times, by this sixth sense [proprioception].1 \r\n\r\nAre bodies and selves something we 'have' or something we 'are'? Interestingly, Sacks use the two formulations interchangeably to express his sense that bodies and selves are intertwined and inseparable. Identity turns on the question of the organism acknowledging or 'owning' what is proper to it; it is this sense of ownership that Sacks invokes when he speaks of the body 'knowing' itself. This bodily knowledge is the basis of selfhood in organisms endowed with consciousness.\r\n\r\n\r\n1 /publication/64
