The Parallax View is Slavoj Žižek's most substantial theoretical work to appear in many years; Žižek himself describes it as his magnum opus. Parallax can be defined as the apparent displacement of an object, caused by a change in observational position. Žižek is interested in the "parallax gap" separating two points between which no synthesis or mediation is possible, linked by an "impossible short circuit" of levels that can never meet. From this consideration of parallax, Žižek begins a rehabilitation of dialectical materialism.
