Summary
Analysis
At sunrise, Frank drives John to “Papa” so that John can get his blessing. On the way, John admires Mount McCabe, comparing it to the hump of a whale. Frank says that, as far as he knows, nobody has climbed to the mount. They talk about Bokononism; Frank says that the only thing sacred to the religion is “man.”
The “whale” comparison is one of a few allusions to Moby Dick in the novel (e.g. John’s suggestion that he be called Jonah in the opening chapter). Moby Dick, interestingly, was called a genuine absurdist novel by Albert Camus. It seems less that “man” is “sacred” in Bokononism, and more that man is its only real ingredient.
