Joseph Heller’s World War II novel Catch-22 is a great example of satire. Joseph Heller had flown bomber missions in WWII, just like his main character Captain John Yossarian, and was tortured by the experience. He found the wartime bureaucracy and logic to be incredibly hypocritical. The most famous example of satire in the book comes from the title, the concept of the Catch 22. This is one of those bureaucratic nightmares in which something can only be done when the thing that precludes it from happening happens. Yossarian eventually discovers that the catch doesn’t even exist, but because everything thinks it does it still has the same effect. And, unfortunately, because it doesn’t exist it can’t be repealed. This is a good metaphor for the entire lack of logic in bureaucracy.
Depending upon their types, different genres have different roles. For example, fiction and dramatic genres help students and writers learn and improve their communication skills. A poetic genre, on the other hand, enhances imaginative and emotional power of the readers. Non-fictional texts and essays help readers develop analytical and persuasive capabilities. However, the major function of genre is to establish a code of behavior between the writers and audience, and keep the readers informed about the topics discussed or the themes presented.
