This is a great question. There are so many quotes or places in the book that can be great for analysis. One of the most interesting quotes of the book comes from chapter 22. It has the merit of showing the writer's style and it is also central to the theme of the book. I will quote a part of it, and you can fill in the rest as you reread the context.
"I can well imagine an atheist’s last words: 'White, white! L-L-Love! My God!'—and the deathbed leap of faith. Whereas the agnostic, if he stays true to his reasonable self, if he stays beholden to dry, yeastless factuality, might try to explain the warm light bathing him by saying, 'Possibly a f-f-failing oxygenation of the b-b-brain,' and, to the very end, lack imagination and miss the better story."
In view of this quote, you can see several things about the style of the author, Yann Martel. First, there is repetition for emphasis. We see this is the doubling of the word, "white." Also we see the "L" in love and "f" in falling being emphasized as well.
We also can see that Martel has a great ability to use dialogue in direct voice to make this points. Also through these points, he is able to get across a sense of anger and contempt.
