A character's culture generally determines his place in this novel's hierarchy. White Europeans, such as Crusoe, are most definitely at the top while natives to the island, such as Friday, are relegated to servant status.
Religion is yet another tool used to enforce the novel's hierarchies. Christians, such as Crusoe, have the moral authority to govern others. Christians are juxtaposed with the paganism of the cannibals and Catholicism of the Spanish.
