Based on the notion of precocity and of the “prematurity of the ego” described by Michel Fain, the author discusses the vicissitudes and functional value of sublimation in relation to precocity/prematurity. Looking at the work of Michel Fain, Benno Rosenberg and André Green, she examines the quality of the latter and puts forward the hypothesis of a “negative of sublimation”. Resulting from an instinctual drive defusion that frees the death drive, this “negative of sublimation” could electively sustain the destructiveness engendered towards the human element. This would induce a perversion of certain artistic or ideological sublimations which would therefore run counter to the Freudian idea, defended in 1927, of a superego resulting from a dialectic between the cultural and the intrapsychic. In 1929, Freud described a “cultural process” involving the renunciation of instinctual satisfactions for the benefit of “a large human community”.
