Throughout both Sophocles' Antigone and Sigmund Freud's
Introductory Lectures On Psycho-Analysis, the various influences behind an individual's decisions are questioned. Freud’s theory of the unconscious and the influence behind an individual’s desire moved away from the outdated idea of those during his time who “thought if you just hit people with all this factual information, they would look at that and say, ‘oh, of course’ (Happiness Machine 9:57 – 10:04). An individual’s decisions are determined by irrational desires driven by the unconscious rather than the illusion given by the individual’s conscious. Freud’s theory surfaces in Antigone as Antigone expresses her determination in burying Polynices. “Go on, make excuses. I am on my way. I’ll heap the earth upon my dearest brother’s grave” (Sophocles 6). Despite her actions involving rebelling against male authority and her own sister’s advice, Antigone states that she has consciously chosen her fate; this goes against Freud’s theory. “Psycho-analysis declares that mental processes are in themselves unconscious” (Freud 25). Thus, Antigone’s “conscious” decision of rebelling against the king was not spawned from a matter of freewill but rather the illusion of it, as her actions were predetermined in her unconscious.
