Catch-22 is a satirical, historical novel by the author
Joseph Heller, first published in 1961. The novel, set during the later stages of word war II, is frequently cited as one of the great literary works of the twentieth century.
The prototypical Catch-22, as formulated by Heller, involves the case of John Yossarian, who wishes to be excused from combat flight duty. In order to be excused, he must submit an official medical diagnosis from his squadron's flight surgeon, demonstrating that he is unfit to fly because he isinsane. In order to get the diagnosis, he must approach the surgeon to ask for one.
A logical formulation of this situation is:
1. (Premise: If a person is excused from flying (E), that must be because they are both insane (I), and request an evaluation (R));
2. (Premise: If a person is insane (I), they should not realise that they are, and would thus have no reason to request an evaluation)
3. (2, Definition of implication: since an insane person would not request an evaluation, it follows that all persons must either not be insane, or not request an evaluation)
4. (3, De Morgan: since all persons must either not be insane, or not request an evaluation, it follows that no person can be both insane and request an evaluation)
5. (4, 1, Modus Tollen: since a person may be excused from flying only if they are both insane and request an evaluation, but no person can be both insane and request an evaluation, it follows that no person can be excused from flying)
The above describes the concept commonly referred to by the phrase “Catch 22”. The book adds an element of complete absurdity to the situation, adding that the same regulations also stipulate that (because flying combat missions is so dangerous) any sane person would not willingly fly combat missions. Thus, any person who flies missions must be insane and thus should only need to be evaluated in order to be excused from flying. However, because requesting an evaluation is a sign of sanity, no pilots are grounded for insanity. The “catch 22” statement is the only reason anyone is in the air at all.
