A new ego cannot be formed directly from the previous ego, but from fragments, more or less elementary products of its disintegration. The relative strength of the ‘unbearable’ excitation determines the degree and depth of the ego’s disintegration.
Ferenczi argues that traumatic disintegration of the ego is the necessary precondition for psychic reformation, with the severity of the stimulus determining the depth of dissolution across a spectrum from altered consciousness to death.
