SHIFTING DEFINITIONS

The person who controls the definitions of words, controls the thoughts of the people. Orwell knew this well as he crafted his dystopian novel, “1984”. In that story, the ruling “Party” used “Newspeak” to control language and definitions to limit the subjects’ ability to think and communicate about ideas that went against the Party.
In the allegory, “Animal Farm”, also by Orwell, citizens endured a set of definitions that constantly shifted to suit the leader’s lust for power. For example, the phrase, “all animals are equal” shifted into “some animals are more equal than others.”
