Explain the saying “History is bunk.” Consider the list of things that the Controller dismisses and suggest a reason for his inclusion of these particular examples of “bunk.” Are there any common themes among them?

Mustapha Mond instructs his citizens to disregard the lessons that history has taught. Mond wants people to believe in science and "progress" rather than old ideas and mistakes. The word "bunk" refers to the frailties and primal loyalties of man that he had no control over. Mond looks to the new model of people who have no individual loyalties to enact the violence and vengeance that was common in the past.
