Lacan sought to redefine psychoanalytic interpretation based on several ideas. He believed interpretations had become too abundant, losing their therapeutic impact. Rather than focus on meaning, Lacan advocated "interventions" to create "waves" across psychic layers. The goal was not for the patient to consciously understand, but for the interpretation to unleash unconscious truth. A true interpretation would extinguish, rather than explain, a symptom through poetic truth. Lacan emphasized that progress occurs through speech itself, not insight into unconscious contents. The analyst must speak oracularly to impact a psyche structured through language and overdetermination.
