Lacan developed his graph of desire in four stages – you find them below. The graphs and the theory behind it can be found in the 1960 essay “The Subversion of the Subject and the Dialectic of Desire in the Freudian Unconscious.”
In: Jacques Lacan, Ecrits, trans. Bruce Fink (New York: W.W.Norton &Company, 2006), p. 435.
The concept of desire is at the center of Lacanian psychoanalysis as a theoretical, ethical and clinical point of reference.
