Individual life is theatrical through and through. You might think that your adherence to some ideal perfectly expresses your uniqueness, that it puts you in the first degree, until you see someone else with the same taste. It's not that the other takes something from you but that they confront you with your own gap in sincerity. Just as a Mexican stand-off type of situation leads to a spiral of "he thinks I think he thinks I think..." the same spiral arises internally the moment you try being totally honest with yourself. There is no perfect and self-sufficient intimacy which is later injured by the awareness that others can see you; the other is already there and is constitutive of what you most regard as your own. The gap, or narcissistic wound if you like, extends all the way down, without limit. You can only accept this by failing to accept it. It is another way of seeing that consciousness is impossible and does not exist.
