Theme in 1984

The theme in my perspective of 1984 is that dictatorship has the power to rule societies minds. This theme exist because for instance, in the book they use double think and use slogans to manipulate minds. For double think in the novel 1984 its states that, "We control matter because we control the mind. Reality is inside the skull." Part 3, Chapter 3, pg. 268. This states that no matter what individuals think and have any sense of being agaisnt the party, The party will contradict them and punish them. Next is "WAR IS PEACE FREEDOM IS SLAVERY IGNORANCE IS STRENGTH." Part 1, Chapter 1, pg. 6. This states that since the supreme power calls the shots, no matter what others will follow because they are scared to be killed. This shows that dictatorship can rule societies minds and that what ever the dictators say they people will follow due to fear of being tortured.
