Harry Potter Voldemort magic wizard Muggles Muggle Lord Voldemort
The social hierarchy of wizards in Rowling's world has drawn debate among critics. "Purebloods" have two wizard parents; "half-bloods" have one; and "Muggle-born" wizards have magical abilities although neither of their parents is a wizard. Lord Voldemort and his followers believe that blood purity is paramount and that Muggles are subhuman. According to the literary scholar Andrew Blake, Harry Potter rejects blood purity as a basis for social division; Suman Gupta agrees that Voldemort's philosophy represents "absolute evil"; and Nel and Eccleshare agree that advocates of racial or blood-based hierarchies are antagonists. Gupta, following Blake, suggests that the essential superiority of wizards over Muggles – wizards can use magic and Muggles cannot – means that the books cannot coherently reject anti-Muggle prejudice by appealing to equality between wizards and Muggles. Rather, according to Gupta, Harry Potter models a form of tolerance based on the "charity and altruism of those belonging to superior races" towards lesser races.
