"Zizek uses “parallax” to refer to situations in which the “same thing,” when viewed from two different perspectives, presents itself to the observer in two completely irreconcilable ways. A good example of this is light, which can be viewed as both a wave and a particle, with no way of mediating between the two positions. Rather than a conflict of two opposing principles, parallax names “the inherent ‘tension,’ gap, noncoincidence” of reality with itself."
