In George Orwell's novel 1984, the concept of Big Brother symbolizes the omnipresent government surveillance and control over citizens. The story is set in a dystopian future where the Party, led by Big Brother, exercises complete authority over thoughts and actions. The narrative introduces Winston Smith, a man who secretly questions the Party's rules but is constantly monitored. The phrase 'Big Brother is Watching You' appears throughout the society, emphasizing constant surveillance. Orwell uses this imagery to depict a government that suppresses individuality and freedom. The novel explores themes of power, manipulation, and the loss of privacy, illustrating a society where every word and action is scrutinized. The phrase 'Thoughtcrime' refers to thoughts opposing the Party, which are outlawed. Orwell's use of language and symbolism paints a picture of a world where freedom is an illusion, and conformity is enforced at all costs.
