Candide: chapters 19 to 24 - A Change in Personality

I believe this series of chapters is also very important for the novel. Candide meets a new passing character which acts kind of as a second Cacambo, and changes his personality and way of thinking a lot. This new character is Martin, and I say he is similar to Cacambo because he also gives me the impression of being a bodyguard to Candide. I say Candide changes his personality because he accepts the new world is no better than the old. This change in personality had started occurring from before when Cacambo insisted they should go back to Europe, before they found Eldorado. However, in chapter XIX Candide definitely accepts the evil in the world. 

" 'Oh Pangloss! cried Candide. 'A scandal like this never occurred to you! But it's 

the truth, and I shall have to renounce that optimism of yours in the end.' " (Pg. 86)

Here we can see Candide is almost completely opposing Pangloss' theory and nature of philosophy. He said that everything was for the best no matter what happened, and now Candide is starting to doubt this, which is what he was taught his whole childhood. Here is when we start seeing the very nature of the satire in this book. The name Candide means optimism, and at this point that is what Candide less is, an optimist. This is both ironic and absurd because his name id optimism but he regrets and complains about everything that happens to him.

I still believe that Martin's appearance will be of more importance further on. What is this character's purpose in the novel? Why is he always cursing life? Is he the cause of Candide's negativism?
