Yes. This book certainly concerns society at that time.

I need some help on figuring out the main idea of "The Adventures of Huckleberry Finn." I know that for most of the part, Huck and Jim float on a raft down the Mississippi River and on the way, they encounter many people and obstacles. At the end of the novel, Finn is also more mature in his words and thoughts.
But, I am having trouble deciding on what the main idea really is and what Twain wants to show. Does it concern the society at that time?

So, it seems like there are various ideas concerned with this book; slavery and how African-Americans were treated, how Huck eventually learns to think for himself, and how torture and abuse did not lead Huck on a "sivilized" path.
Right!
