"It's not about doing something shameful. It's about doing something private. It's about your life belonging to you" (Doctorow 57).
The idea in Little Brother that made me think the most was the idea of personal privacy and why that is so important. On page 57, Marcus compares a betrayal of personal privacy to a situation where you had to use the bathroom in a glass box in the middle of New York City every time you had to go. Everyone uses the bathroom, but it is a private and personal part of our lives, not something we want to share with everyone. So while Marcus didn't have anything really illegal, and definitely not at all related to the terrorist attack, on his phone, he didn't want to give "severe haircut lady" his password because his phone had private information that was his personal space. Throughout the novel, Doctorow explores the balance of protecting privacy and stopping terrorism. Homeland Security's efforts to find terrorists causes divorces and fights, things brought to light when their privacy was compromised. Xnet begins in the first place so kids can play video games and email away from the snooping DHS. This widespread desire for a private corner of our lives is why cryptography is so prevalent in our lives. As Vanderbilt students, our emails, web browsing, and phone calls are likely (and hopefully) nothing illegal: emailing professors about homework, calling home to parents, and ordering a pizza. But that doesn't mean that we want everyone to be able to see that. Cryptography allows everyone a sense of privacy and a way to create that privacy. However in this novel, Doctorow asks an important question: how much of this personal privacy are we willing to give up in the face of terrorism? Whether you agree more with Marcus or his dad, I think everyone would agree that the government in Little Brother gave far too little respect to personal privacy.
