Statement 8

“Psyche is the only one who knows nothing (nothing of herself, of her extension, of her recumbent being-extended); but further, by being alone in knowing nothing of this, she is alone for not knowing anything of this. She finds herself alone without knowing it; her solitude is radical because she knows nothing of herself, of her extension, of that which others know; she doesn't know what they know and that they know, that is, the content and the fact of their knowledge. On the subject of herself. Indeed, she is the submissive subject (extended object), the support or subjectile of their knowledge but not of hers because on her own she knows nothing of herself - on the subject of herself.” 

(Jacques Derrida: On Touching, 15)
