This article explores the emergence of hopefulness as a potentiality contained in the trust established at an early stage between the baby and its environment. Hopefulness emerges as a possible vicissitude and something beyond this trust, implying that the primary processes of symbolization can be mobilized, particularly in the transference. The experience of primary trust is characterized by the creation of present moments arising from a particular dynamic of being at once the same as and a double of the object. The temporal horizon represented by hopefulness will open out from this base. Traumatic revivals in analysis, examined here in the light of the clinical case of a female patient in exile, can lead to a re-experiencing of the betrayal of primary trust which makes it possible, within this process of disillusionment, for a psychic movement towards the otherness of hopefulness to emerge.
