First explanation by Doc Daneeka

The Catch Defined
The Rule
Doc Daneeka explains Catch-22 to Yossarian: a concern for one's own safety in the face of real danger is the process of a rational mind. Orr is crazy and can be grounded if he asks, but asking proves he is sane, so he must fly.
The Simplicity
Yossarian is impressed by the elegant trap. It is a perfect circular logic. There is no way out. The catch is that there is no catch—it is a self-sealing loop.
The Implication
This conversation establishes the novel's central theme: the absurdity of systems that trap individuals. Yossarian realizes that the only way to beat the catch is to refuse to play.
Catch-22 and the mission count

The Catch Applied
The Higher Authority
Yossarian learns that Twenty-seventh Air Force requires only forty missions, but Colonel Cathcart demands fifty-five. He asks ex-P.F.C. Wintergreen what would happen if he refused. Wintergreen says they would shoot him.
The Logic
Catch-22 says he must obey any order from his commanding officer, even if it contradicts higher orders. The catch is that he has no recourse. The system is designed to keep him flying.
The Trap Tightens
Yossarian sees that the catch is not a single rule but a principle that can be invoked arbitrarily. It is the ultimate bureaucratic weapon.
Catch-22 and the hospital

The Catch in Medicine
The Liver Condition
Yossarian feigns a liver condition to stay in the hospital. The doctors cannot treat it because it is not jaundice. They cannot discharge him because it might become jaundice. He is stuck in a medical catch.
The Soldier in White
The soldier in white is a perfect example: he is kept alive by a system that drips fluid into him and drains it out. No one knows if he is conscious. He is a human machine, trapped in a medical catch.
The C.I.D. Man
The C.I.D. man investigating Washington Irving is also caught: he cannot report his findings because his reports are censored. The catch protects the forger.
Catch-22 and the brothel raid

The Catch in Society
The Old Woman's Explanation
Yossarian returns to Rome to find the brothel empty. The old woman tells him the M.P.s chased the girls out, citing Catch-22. When asked what Catch-22 is, she says it means they have a right to do anything they can stop you from doing.
The Absence of a Written Rule
Yossarian realizes Catch-22 does not exist as a written law. It is a justification for power. The M.P.s do not need to show it; they simply invoke it.
The Universal Trap
This episode shows that Catch-22 is not just a military rule but a principle of arbitrary authority. It can be used anywhere to silence opposition.
Catch-22 and the deal

The Catch in the Deal
The Offer
Colonel Korn tells Yossarian they will send him home a hero if he agrees to like them and keep quiet. Yossarian accepts, but then realizes the catch: he must betray his principles and the other men.
The Moral Trap
If he takes the deal, he becomes a hypocrite. If he refuses, he faces court-martial. The catch is that there is no honorable way out. He must choose between his life and his integrity.
The Escape
Yossarian ultimately rejects the deal and runs away. He breaks the catch by refusing to play the game. Orr's example shows that escape is possible through cunning and perseverance.
