This work is a second thought of Bion’s concept of intuition in order to resolve some misunderstandings. The author argues that intuition has two aspects: one facing the past, the other facing the future. The first is a kind of intuitive reading of the unconscious to discover the invariant; the second is directed to growth, to become the true Self, through the process of at-one-ment and dreaming the session. This double movement of intuition is precisely what current neuroscience highlights. The author emphasizes that Bion introduces the concept of intuition from the beginning, not so much as an expression of a tension towards mysticism but as an expression of his rejection of the positivist paradigm and of the use of a new epistemology linked to Bergson, Poincaré, Husserl, and Whitehead.
