The essay focuses on political language, which, according to Orwell, "is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind." Orwell believed that the language used was necessarily vague or meaningless because it was intended to hide the truth rather than express it. This unclear prose was a "contagion" which had spread to those who did not intend to hide the truth, and it concealed a writer's thoughts from himself and others. Orwell encourages concreteness and clarity instead of vagueness, and individuality over political conformity.
