Žižek on the Process of Symbolic Identification

From Žižek's The Fragile Absolute (London: Verso, 2000), pp. 49-50:

"And it is crucial to note how this passage from symbolic identification to identification with the excremental leftover turns around--accomplishes in the opposite direction--the process of symbolic identification. That is to say, the ultimate paradox of the strict psychoanalytic notion of symbolic identification is that it is by definition a misidentification, the identification with the way the Other(s) misperceive(s) me. Let us take the most elementary example: as a father, I know I am an unprincipled weakling; but, at the same time, I do not want to disappoint my son, who sees in me what I am not: a person of dignity and strong principles, ready to take risks for a just cause--so I identify with this misperception of me, and truly 'become myself' when I, in effect, start to act according to this misperception (ashamed to appear to my son as I really am, I actually accomplish heroic acts). In other words, if we are to account for symbolic identification, it is not enough to refer to the opposition between the way I appear to others and the way I really am: symbolic identification occurs when the way I appear to others becomes more important to me than the psychological reality 'beneath my social mask', forcing me to do things I would never be able to accomplish 'from within myself'."
