What is the theme of the play, The frogs?
The theme of the play "The Frogs" is the demonstration of how the influence of the old tendencies and schools of art and thought of Athens made its citizens much more chivarlous, productive, democratic, and sound than the newer schools of thought which led to the wars that are now draining Athens.
Aristophanes was trying to make a point: The newer schools of thought are too focused on form and not on essence, hence, they deviate the citizens from the common life, in order to have them consume themselves completely to art or philosophy.
Contrarily, the old schools would be a way of life that is combined with everyday life, and served more as a moral, mental and spiritual resource, rather than a way of life. Given that the situation after the Peloponesyan war left the city in such dire straights, Aristophanes proposed (in his comedic ways) that, instead of a politician, it would be a dramatist who would fix the place and turn it around. The situations that arise throughout the play give the story an exquisite flavor of comedy and sarcasm that makes it clear to the audience where Aristophanes was going.
