"Cathc-22 stated that concern for one's own safety in the face of dangers that are real and immediate is the process of a rational mind." Direct quote from Joseph Heller's book Catch-22, I have forgotten the page number. The following is a paraphrase of Yossarian's (the main character) observation of how Catch-22 worked in practice.
Catch-22: If you are insane you will be released from combat, all you have to do is ask. If you ask, however, it proves that you are sane and you have to fly more missions. If you fly more missions you are insane and do not have to, if you don't want to fly more missions you are sane and have to fly them.
Later in the book, Catch-22 becomes boiled down to "we have the right to do anything you cannot stop us from doing." (Another direct quote from Heller, again I have forgotten the page.) This last definition is kind of applicable in this election, don't you think?
