The first explanation

The Trap Defined
The Rule
Doc Daneeka explains Catch-22: a concern for safety is rational, so anyone who wants to be grounded is sane and must fly.
The Implication
The catch is that there is no way out. It is a self-sealing loop. It represents the absurdity of bureaucracy.
The Symbol
Catch-22 becomes a metaphor for any system that traps individuals in contradictory rules.
The catch in action

The Applications
The Mission Count
Cathcart raises missions arbitrarily. The men must obey because Catch-22 says they must obey orders.
The Hospital
Yossarian cannot be discharged because his liver condition is not jaundice. He cannot be treated because it is not jaundice. He is stuck.
The Brothel
The M.P.s invoke Catch-22 to evict the girls. There is no written rule, but the catch justifies any action.
The catch as a weapon

The Final Trap
The Deal
Cathcart and Korn offer Yossarian a way out, but the catch is that he must betray his principles.
The Choice
He can either accept the deal and become a hypocrite, or refuse and face court-martial. There is no honorable option.
The Escape
Yossarian breaks the catch by refusing to play. He runs away. The catch only works if you accept its premises.
