This paper explores the ontological and developmental foundations of creative thinking in psychoanalysis, distinguishing it from defensive intellectual thinking. Drawing on Segal’s view of truth and Bion’s conception of O, it proposes that genuine creativity arises not from defensive intellect but from attunement to O/Dao—the living source of truth.

Such attunement unfolds in the state of contained undifferentiated oneness (CUO)—a contained, undivided mode of being that remains receptive and holds infinite potential for differentiation. Developmentally, the fetal experience within the maternal womb represents the prototype of CUO, whose experiential continuity rests on containment. When the primal skin sufficiently carries this containing function, the experience of oneness endures and creative differentiation can unfold; when containment falters, this oneness becomes obscured or fragmented, and second-skin mechanisms and adhesive identifications arise, offering illusory safety through omnipotent control and giving rise to defensive intellectual thinking.

Two clinical illustrations show how defensive you wei (有为) obstructs contact with truth, whereas a shift toward wu wei(无为) within analysis allows creative thought to arise as the quiet, natural unfolding of being itself.
