I am doing a philosophy essay on the novels of Kurt Vonnegut.
The topic is: criticise modern civilization through the novels of Kurt Vonnegut, refrences are Slaughterhouse-five and Breakfast of Champions.

I was wondering if there were common themes running through both book pertaining to the essay topic.

Such as Kurt Vonneguts beleifs in humanism, free will, determisism.

Specific examples from both novels would be helpful.
