This dissertation analyses literature written by the psychoanalyst and artist Marion Milner, in relation to creativity. The focus of this research is Milner’s personal, creative process in order to bring further understanding as to how a psychotherapist can facilitate creativity for optimal practice. An interpretative methodology informed this study, which utilised a method of thematic analysis. The themes identified in this study have been conceptualised as a psychological model (Ego, Duality and Oneness) which addresses the way we can process lived experience to elicit psychic growth through an act of creative surrender – in order to develop the capacity to think unknown thoughts and to further awareness and freedom. The significance of creativity for clinical practice and a critical reflection of this research are discussed.
