In the eyes of Kleinian theory, envy is seen in its innate, constitutional aspect and as a primary expression of the death drive. However, other theorizations open the envy to a different conception, which make it composite and introduce into its understanding a global sexual dimension of which the mere orality only partially accounts. François Mauriac illustrates in his novel Genitrix several types of envy. The author of this article is based on what the English psychoanalyst Walter G. Joffe developed in his 1969 article and underlines how envy can, clinically, be apprehended in crises, during which the overwhelmed oedipal attractor doesn’t more organize the classic path of the drive. The notion of territoriality in its deeply narcissistic aspect contributes to the analysis of envy, in particular when the figuration of incest takes center stage.
