Read the literary analysis written by Emery about part 3 of The Call of the Wild.One of the major themes of The Call of the Wild is that both civilization and the wilderness have social structures. Buck is faced with—and must learn about—social structures from the very outset of the novel. In the beginning, Buck lives at Judge Miller’s place, where he is clearly "ruled." As the novel progresses, Buck learns to fear the "club" when it is yielded by certain masters. Later in the novel, Buck is forced to fight for a position of leadership among his sledmates or among those who threaten their existence and safety. Throughout the story, Buck learns that social structures exist everywhere.
