Psychological theories can be represented all throughout Marjane Satrapi’s Persepolis. A common theme to be noticed is the effect the events happening around Margi had on her personality. In ‘the letter’ Marji speaks about being ashamed because while she sits in her father’s Cadillac, others are living different lifestyles and working at very young ages. This can be found in the quote ” He told sad but true stories; Reza becomes a porter at the age of ten. Leila wove carpets at age five. Hassan, three years old, cleaned car windows.” She comes to a realization that this is because of the difference between social classes. Marji sees that she was in a completely different social class than the other characters mentioned. This all relates back to the core of the Marxist theory. Another example of the theory can be found in ‘the letter’ when Marji struggles to accept that people are defined by their social class, and that where they are born is where they’ll stay. She argues with her father who says that ” their love was impossible because in this country you must stay within your own social class” in regards to their maid who fell in love with their neighbor. Margi fights back with “but is it her fault that she was born where she was born?” Famous psychological theories can be founded multiple times in Persepolis. In Freud’s theory of psychoanalysis, he says that personality is formed through conflicts among 3 fundamental structures of the human mind; the ID, ego, and superego. In the chapter ‘ the veil’ the parents of Marji question her as to what she wants to be when she’s older. Marji answers by lying by saying she wants to be a doctor when in fact she believes she will be a prophet. Later when God supposedly questions her on her answer she defends with ” I felt guilty towards god….. I will be a prophet but they mustn’t know.” It’s to be assumed that this is an example of Freud’s ‘ego’ where she lies to satisfy her parents but later feels guilty towards god. Erick Erickson also created the theory that stems from Freud’s. Erickson created the theory of psychosocial stages. Marji is in the fourth stage of Industry vs. Inferiority. In ‘The water cell’ she is very influenced by her school and peers. An example of this is when she explains ” he did so! Its written on the first page of our school books” in reply to her father’s statement that the king was not picked by God. Marji’s view on things is easily persuaded by her teacher Because it is written in the book, it must be true.
