Psychoanalytic criticism is a form of literary criticism, which uses some of the techniques of psychoanalysis in the interpretation of literature. One of the most widespread psychoanalytic theorists after Freud was Jacques Lacan. In his text "The Meaning of the Phallus", he asserts that the idea of ​​the two sexes is based on masculine "being" and feminine "having", and that these two differences determine the relations between the sexes while at the same time getting closer. together. For Lacan, the phallus for men represents power, authority and desire while for women, the phallus signifies the lack of power and action (182). Another important text by Lacan is “The agency of the letter in the unconscious or reason since Freud”. This text explains that language does not shape our identities and desires so much as our identities and desires are acquired from language (Richter 1046). Lacan explains that the symbolic stage is made up of the Other and that the Other is not complete because there is a lack. This concept suggests that a signifier is always missing in the set of signifiers composed by the Other. Lacan then affirms that the subject is now governed by language and that this symbolic discourse forms the structures of cultural and social identities (Richter 1046). Lacan also describes the use of metonymy and it is a mode of symbolization in which one thing is signified by another which is associated with it, but which is not of the same class. Additionally, metonymy is characterized by lack, oppression, and servitude (Berry 107). Lacan's psychoanalytic theories can be easily applied to the character of Lady Macbeth in William Shakespeare's play Macbeth. When Macbeth was written in the early 17th century, the masculine was in the middle of the paper......his and the husbands. Although Lady Macbeth thinks she has convinced Macbeth to kill Duncan, she decides to carry out the deed herself. When Lady Macbeth arrives at the king's chambers, she cannot execute the king. Lady Macbeth expressly rejects the masculine power that would allow her to wield a dagger. As she argues in favor of killing Duncan, even stating that "if he hadn't looked / like my father in his sleep, I wouldn't have done it" (2.2.12-13). According to Chamberlain, “Lady Macbeth ultimately rejects male authority. What she longs for instead is an alternative gender identity, one that will allow her to free herself from the emotional and cultural constraints that govern women” (79). Additionally, Lady Macbeth's submissive role plays a significant role in her failure to kill Duncan, as she views the king as the ultimate symbol of male authority..
