The collection of pieces put together represents the theme of desire that can be seen in both Sophocles' Antigone and Freud's Introductory Lectures. Freud introduces the Id, Ego and Superego which all explain how people handle their conscious desires and unconscious desires (Freud 103). In Antigone it can be seen through many examples of how Freud’s idea of repressed desires comes into play. It becomes harder and harder to keep unconscious desires repressed as we can see though the King’s son Heamon in Antigone. It is difficult to behave the way that society wants when there are repressed desires in ones’ unconscious.
