When the Air Force realizes that Yossarian cannot be dissuaded, the officers try to make a deal with Yossarian that will allow him to fly no further missions. The only catch is that the deal is ethically repulsive to him; they will send him home as long as he likes them. If he does not give in, he will be court-martialed for being involved in black market practices. Yossarian protests against such wrongful accusations, but the officers claim they are justified in jailing an innocent man to keep the war effort going. Left without any other choice, Yossarian runs away both to avoid a court-martial and to avoid Nately's whore, who is trying to kill him to avenge Nately's death. The confusion of wartime life is not resolved.
Barzun’s critique of the cult of evolutionary theory and the canonisation of Darwin himself is impressive but it is difficult to identify where Barzun stands on the scientific status of evolutionary theory and this is the least convincing part of his work. He appears to be dissatisfied with materialism and determinism without explaining whether he adhered to vitalism, or some form of mysticism or religion. This underlines the problem of pursuing such a wide-ranging research project without the assistance of co-workers, so his reach may have exceeded his grasp at some points. This is especially apparent when he attempted to locate his work in the context of twentieth century physics and biology, where he was operating too far from his base in history and cultural studies.
