Jacques Lacan's paper 'Le Stade du Miroir' (1949) has certainly influenced me. He refers to the use of the mirror in each individual's ego development. However, Lacan does not think of the mirror in terms of the mother's face in the way that I wish to do here.
Winnicott explicitly invokes and revises Lacan's Mirror Stage, arguing that the true developmental mirror is the mother's responsive face rather than an optical surface, thereby repositioning the concept within an object-relational and intersubjective frame.
