In the past few days, 1984 by George Orwell has re-emerged at the top of best-seller lists.
The dystopian novel chronicles the tale of a British man named Winston who works at the Ministry of Truth, which oversees all media and propaganda. In a move similar to the one made by Guy Montag in Fahrenheit 451, Winston turns against his job, employer, and country... He starts to journal his anti-Big-Brother thoughts. His following experiences with the secret underground society The Brotherhood, the Thought Police, and a woman named Julia.
This classic coined many terms we still use today, like "Big Brother," "thought-crime," and "Newspeak," and it popularized the use of the word "Orwellian" to describe totalitarian states' surveillance of their citizens and manipulation of historical record.
