1. Jacques Lacan developed psychoanalysis using concepts from linguistics, philosophy, and semiotics. He saw the unconscious as structured like a language.
2. Lacan believed human desire is shaped by our entry into language and separation from the "real" experience of the world. Through this process, we become subjects divided between the imaginary, symbolic, and real orders.
3. A key concept is the "mirror stage," where infants first recognize themselves through their mirror image, laying the groundwork for the imaginary order of identifications, ideals, and narcissism. This establishes the "I" but also begins the lifelong process of seeking recognition from the "Other."
