Strepsiades attempts to enroll in Socrates's special school for sophists in order to learn the slippery, dishonest Unjust Argument that will help him get the better of his creditors in court. He learns many strange and wonderful things about atheism, natural sciences, and proper nouns. However, he proves an impossible pupil and thus decides to enroll his spend-thrift son Pheidippides instead. Pheidippides masters the slippery rhetoric of the Unjust Argument.
