Two things about the slave scene that really stuck out to me:

1. The slave's mother was the one who sold him
2. The quote where he says, "That's the price of your eating sugar in Europe." 

This might be a really farfetched idea but that's what Honors is all about, right?  I think that Voltaire wanted the slave to represent the New World and his mother, who sold him, to represent England the "mother"- country. The land in the New World was never owned until the Europeans  came because the Indians believed that land was too sacred to be bought and sold, just as human beings were not meant to be owned. However, the European settlers, especially the conquistadors, disregarded these beliefs and treated the land as property just as they had in Europe. While the majority of settlers came to America in search of  refuge and new opportunities, the slave that Candide meets was forced to leave his country and found bondage instead of freedom.

2.  "That's the price of your eating sugar in Europe." When I first read this quote, I couldn't help but think about the real price of our freedom. Living in such a safe country, we tend to forget how much was sacrificed so that our families could feel safe, for the most part, as they go about their daily lives. Freedom is our sugar. We could live without it, but who would want to?! However, the majority of nations in this world have never tasted complete freedom like we have. Here, whether Voltaire intended him to or not, the slave represents everything that America (especially our troops and Founding Fathers) has endured to ensure our safety and protect other nations as best we can so that they may "eat sugar".
