I feel that the character, Dances with Wolves, represents the ability of a human to learn and accept changes within the world and our culture. At first, Dances with Wolves was defensive and hesitant, but as he got to know the people of the Sioux tribe he slowly became a part of their tribe. He realized after spending time with the tribe that they are not the stereotypical Indians that he was taught. He ends up learning their customs, befriending many of the people, and eventually marrying one of them.
In a way, this film is what Roger Ebert describes a "sentimental fantasy, a "what if" film that imagines a world in which whites were genuinely interested in learning about a Native American culture." This film depicts what it would've been like if a white American came across a Native American tribe and how they would've interacted. It makes us think of how the American soldiers back then should have been treated the tribes and provides us with a lesson for how we treat people in the future.
