D.W. Winnicott on "Potential Space"

Potential space is infused with primitive creativity, which later extends to all cultural phenomena, such as the areas of play and artistic creativity and appreciation, and of religious feeling, and of dreaming and also of fetishism, lying and stealing, the origin and loss of affectionate feeling, drug addiction, the talisman of obsessional rituals.
