Deconstruction began in the 1960s with Jacques Derrida and other theorists who took structuralism to its logical extreme. They argued that language is unstable and meanings are uncertain. Deconstruction involves carefully analyzing texts to uncover inconsistencies and contradictions. This reveals the complex foundations that are difficult to interpret definitively. The process involves two phases - first reversing hierarchies, then neutralizing binary oppositions to arrive at undecidable meanings. Deconstruction has been applied to analyze various literary works.
