Need help to write about The Greek Imperative (Antigone)

Theory: the beliefs of a culture can be seen through art it produces. 

Rationalism: beliefs that a person should be driven by wisdom instead of emotions. 

Humanism: beliefs that humans are the center of all things. 

Idealism: belief that a person should strive for perfection even though it is not attainable. 

Explain how the concepts of rationalism idealism and humanism are shown though the words or actions of 3 characters in Antigone. You can read the script or watch it on youtube.
