The Voice Dialogue method, also known as the Psychology of Selves, was developed in the 1970s by Californian psychologists Hal and Sidra Stone. Voice Dialogue is a precisely refined methodology that involves the facilitator (therapist) engaging in a real dialogue with the client's subpersonalities. The creators of the method believe that perceiving oneself as a single, unified "I" is fundamentally incorrect. They propose that the "I" consists of multiple subpersonalities, each with its own voice, history, feelings, goals, and even claims. These inner voices, belonging to different parts of our personality, create our character and define our life roles. These voices maintain a constant internal dialogue in the form of justifications, criticisms, explanations, etc.
The method is based on the ideas of C.G. Jung and intersects with various theories and schools, from ancient Greek theater to psychodrama and Hermann Hesse's "Steppenwolf," from Gurdjieff to family constellations by Hellinger, from Aurobindo's integral yoga to gestalt therapy and process-oriented therapy. However, Voice Dialogue stands out from other psychological approaches due to its simplicity and elegance, which often surprises with its effectiveness in solving problems and facilitating inner transformation for both the client and the facilitator.
