The idea that only “borderlines” are split, broken and divided is according to, Lacan’s way of thinking, predicated on the ego-psychological (and common) illusion that there is a normal state of “wholeness” and “unity.” The belief in an integrated self, according to Lacan, is a function of our taking our “specular image” for the real subject. Another of the effects of the mirror stage is the illusion of autonomy. Any adult who is questioned about himself will insist that he knows that he is free, knows what he wants and he has to do, etc. because he is his own person..
