Post-structuralism emerged as a critical response to structuralism in 20th century French philosophy. It rejects the idea that meaning is fixed or that a text has a single, definable purpose. Post-structuralism emphasizes that meaning is dependent on the reader's own context and experiences. It views identity as complex and shifting rather than singular, and seeks to deconstruct assumptions and power structures through analyzing how meaning changes based on perspectives. The goal is a multifaceted interpretation of texts through considering many variables like culture, identity and knowledge systems.
