Lacanian Theory is a psychoanalytic framework developed by French psychiatrist Jacques Lacan. It emphasizes the importance of language and the unconscious in shaping human behavior and identity. Lacan proposed that the unconscious is structured like a language, meaning that our desires and motivations are influenced by linguistic and symbolic systems. A key concept in Lacanian Theory is the mirror stage, where infants recognize their reflection, leading to the formation of the self. This stage highlights the tension between the ideal self and the actual self, influencing how individuals perceive themselves and relate to others throughout their lives.
