How we cite our quotes: (Chapter.Paragraph)
Quote #1
In addition, no one today remembered why the war had come about or who, if anyone, had won. The dust which had contaminated most of the planet's surface had originated in no country, and no one, even the wartime enemy, had planned on it. (2.3)
At first, you might read this quote and think, "Isn't who won a world war kind of an important detail to remember?" But here, memory isn't so much faulty as it is chosen. Who won isn't as important a detail for these future citizens as the condition of the world.
Quote #2
The TV set shouted, "—duplicates the halcyon days of the pre-Civil War Southern states! Either as body servants or tireless field hands, the custom-tailored humanoid robot—designed specifically for YOUR UNIQUE NEEDS, FOR YOU AND YOU ALONE—given to you on your arrival absolutely free […]." (2.8)
Have you've heard of selective memory, the ability to basically select what you do or do not remember? Here's a whole bunch of social-selective memory on display. Sure, the pre-Civil War South could be described as "halcyon" for some people—hoop-skirt-wearing, plantation-owning people. But this future society seems to have selectively forgotten the many people who didn't find slavery such a great thing. Like the slaves.
Quote #3
To Eldon Rosen, who slumped morosely by the door of the room, he said, "Does she know?" Sometimes they didn't; false memories had been tried various times, generally in the mistaken idea that through them, reactions to testing would be altered. (5.89)
Most faulty memory in Do Androids Dream? comes from people being perfectly human, by which we mean imperfect. Here, faulty memory comes directly from people trying to alter memory to their advantage. Look out for men wearing dark sunglasses and holding shiny objects, is all we're saying.
