The problem with all bivalent notions is that they collapse without their polar opposite. When we define our 'self' against the 'other', we come to need the other. And, when, in the absence of a true opposite, one is contrived, our conception of ourselves becomes as distorted as our concept of the other. Ultimately this process of defining ourselves against the 'other' only serves to strengthen the other's position.
